Inside a Docker container, 127.0.0.1 refuses connections coming from Dokploy's internal proxy. We can bypass this easily by installing socat—a lightweight network relay—inside the container. It acts as a safe bridge: Dokploy talks to socat on 0.0.0.0:3080, and socat passes the traffic internally to the app on 127.0.0.1:3081.
ost Binding: dsh web is binding strictly to 127.0.0.1:3080 inside the container. Dokploy's proxy routes traffic using the container's internal network IP, which gets rejected because the app is only listening to local loopback inside its isolated shell.
Browser Crashes: It is attempting to spawn a desktop browser inside a headless Docker Linux container, which causes the command to crash with [ELIFECYCLE] Command failed (as seen in Containers 2 and 3).
Review follow-ups: the Agent Note triplet moves to implemented/ rewritten as
shipped state (Decision/Consequences/Testing, present tense), cross-linked
both ways with the 2026-07-28 storage recovery proposal whose projcache
reset/destroy path it supersedes (that proposal stays live for authoritative
and whole-medium damage). The fixtures spec header and the note state the
fixture provenance as recorded facts of the released builds instead of
citing local tooling, and the spec JSDoc points at the note's final home.
The proposed Agent Note records the three shipped on-disk generations of
session_projcache, the read-compat and backup-and-skip decisions, the
upgrade matrix, and the rejected alternatives. The package README documents
the upgrade guarantees and requires every future schema or domain-version
change to land with archived fixtures and tests proving its upgrade story.
The storage subsystem page and the generated cordis catalog pick up the new
DomainSpec fields.
The session_projcache domain declares compatibleVersions: [3, 4] and
invalidRecords: 'backup-and-skip'. The two lineage identity fields become
optional — records admitted from older versions predate them, and the single
reader (identityMatches) interprets absence as the unseeded lineage: exact
for unseeded sessions, while a seeded caller fails the match and refolds
cold, so the lineage binding keeps its protection. Upgraded homes therefore
boot and serve their cached listing titles immediately, including homes
whose new tree already holds current-stamped documents without lineage
fields, and a record failing validation anyway is backed up and skipped
instead of refusing the plugin tree.
tests/fixtures/ archives the real on-disk media of every shipped generation
(v3 whole-unit file, v4 and v5 per-record documents, and the lineage-less
current-stamped shape); fixtures.spec.ts proves each recovers through the
real storage stack, rewrites to the current format on the next live write,
and that a hopeless record is salvaged without costing the boot.
A DomainSpec may declare compatibleVersions: older domain versions whose
stored records the current record schemas still accept. The json backend's
per-record reads admit documents stamped with a declared version (writes
always stamp the current one), and the legacy whole-unit bootstrap migrates
only a file whose stored version is in the accepted set — previously it
migrated any version and stamped the records current, turning a discardable
stale cache into invalid-record failures that refused the whole domain at
open and permanently poisoned the new tree on first boot.
A DomainSpec may also declare invalidRecords: 'backup-and-skip' for domains
whose records are disposable derived data: a stored record failing its zod
schema is moved aside through the new optional KvUnit.backupRecord
(<key>.json.bak.<YYYYMMDDHHmm> under the json backend), logged with its
cause, and skipped, instead of rejecting the open. The default stays
fail-loud, and so do backends without backupRecord.
Refusing a response whose tool call never receives an identity needed a new
failure code, a change to the default retryable set, and a `[DONE]` gate that
overrode the finish reason a provider had already sent — turning a safe
`max-tokens` truncation into up to five retries. The lenient wire it guarded
against is hypothetical: no report describes a stream that omits identity
entirely, and the pre-existing test for it is labelled as such.
Only `acceptIdentity` and the widened wire types remain. They close the
reported erasure and cannot reach a worse outcome than the previous
assignment, because the set of inputs that assign only narrows.
`LlmRuntime.adapterStream` normalizes a thrown `LlmError` into the same error
`finish` the loop routes to `agent/request-error`, so throwing would reach
retry too. The Note claimed otherwise. Yielding is chosen because it reports
the attempt's billed usage first and matches the neighbouring `EMPTY_RESPONSE`
refusal.
The rejection comment repeats the corrected durability wording, and the
assembler's delta-only fallback carries a TODO for the empty name it still
invents for adapters that never close a tool-call block.
The `MALFORMED_TOOL_CALL` JSDoc claimed nothing durable is written, but the
loop appends an `assistant/chunk` for every yielded chunk; only the assistant
message and tool result are withheld. The bounded-recovery Note still listed
a five-code transient set, and neither Note linked the other.
A keyless `malformed-tool-call-retry` scenario now records the refusal, the
retry, and the absence of a `tool/call` for the failed attempt. A translator
case pins that an already closable block also withholds its `block-end`.
Adding `MALFORMED_TOOL_CALL` to the default retryable set changes two
expected outputs the session snapshot lane does not own: the shipped Web
composition's inline snapshot, and the canonical packed layout of the
refreshed `empty-response-retry` fixture.
The persistence seam is now create/open/stat/list returning per-session
SessionHandles (read/append/flush/close); every log read and write flows
through the owning handle. The seam package exports only the service and
handle contracts, consumer-visible errors, and pure durable-data
validation helpers; each backend owns its complete storage runtime, and
the shared contract suites pin equivalent observable behavior. The
backend routes published sessions' live events by id into the active
write handle; agent-loop only acquires, seeds, and closes the handle.
Resume appends interruptedTurnClosers through its write handle;
session-query owns the revision-keyed cold cache. Legacy-only surfaces
are removed in the same swap: locate/readRaw/supportsRawArtifacts, the
legacy event-shape read migration, zstd torn-frame salvage,
DSH_SESSION_JSONL, and hook transcript_path population; a torn final
zstd frame is discarded whole; the session-list cold blank probe returns
on stat metadata (eventCount derived from the last physical row,
sizeBytes). The WebUI ZIP export serializes the logical log from a read
handle, so both backends export identically.
Refs #3245
A continuation SSE delta that repeats a tool call's `id` or `name` as an
empty string — or as `null`, which some OpenAI-compatible gateways send —
erased the identity established by the call's first delta. The assembled
block reached the loop with an empty name and failed as `unknown tool ""`,
and the empty `callId` persisted into `tool/result`, which the session
reader refuses on reopen.
`acceptIdentity` accepts only a non-empty string, so a repeated empty or
null field means "no update". A tool call still missing `id` or `name` at
`[DONE]` ends the response with the new retryable `MALFORMED_TOOL_CALL`
code instead of closing an unusable block.
The code-mode → ptc rename rewrote Cloudflare's product name in the
link text and the external URL path, leaving "PTC mode" pointing at
https://blog.cloudflare.com/ptc/ (404). Restore Cloudflare's own name
and the working https://blog.cloudflare.com/code-mode/ link in both
the English and Chinese notes.
The two styling notes name the surveyed product; the mechanism facts
(superellipse token, guard, full-round opt-out, stroke-in-shadow
elevation, 0.5px hairline) stand alone, so the notes now state them
without the product reference. Pairing records re-recorded.
The composer hairline moves one step up from the menus' l1; the seven
menu-fill dropdown cards grow from 16px to 20px corners. Notes and the
token comment record the new layering.
Re-declare the derived elevation tokens on body * so per-surface
--dsw-elevation-stroke-color rebinds reach the consuming shadow (custom
properties inherit with var() already substituted); pin that mechanism
and add synthetic rejection cases to the stylesheet scans; take the
ring-track basenames through node:path so the exemption matches on
Windows; update the ModelsSection row-card spec to the hairline recipe;
align the elevation note with the shipped l1 menu rebind, refresh the
feedback-popover note's surface recipe, and document the soft tier.
Apply global visual polish across the web client: corner-shape:
superellipse(1.5) with corner-shape: round pairing for full circles,
elevation tokens that draw 0.5px stroke outlines inside box-shadow for
floating surfaces, 0.5px hairline borders and divider lines for
neutral-token strokes, and tuned stroke contrast plus larger radii for
menus, settings panels, and cards. Stylesheet-scan specs in ui-theme
reject unpaired circles, border+shadow mixes, and 1px neutral hairlines
repo-wide.
Closes#3287
Review follow-up: the per-step gate recomputed view(previous) on every
changed apply — a property read for identity-stable views, but a fresh
throwaway object per change for computing views. The registry now keeps a
WeakMap from state object to raw view: the previous state's view was
cached when that state was current, so each distinct state's view computes
exactly once (gate and snapshot share the memo) and the quiet path
allocates nothing. Unlike the earlier lastView record, an entry is keyed
by the state itself — the view of that exact state by the pure-view
contract — so no stamping discipline exists to get wrong. Primitive
states bypass the WeakMap and compute directly.
Review consensus: for the only declaring unit the token function was
literally the view function, so the extra wire member bought nothing —
default raw-view comparison produces the identical Object.is on
state.turns at the identical cost (one property read per side). The
per-step gate stays: it holds the no-stored-baseline property, and its
measured overhead (~ns per changed state) is four orders of magnitude
below the push path it guards.
Review follow-up (imccyu): comparing view(previous) recomputes the view on
every quiet change. The wire block now takes an optional viewKey(state)
declaring the cheap comparison token; the drive compares tokens across the
previous and next states and calls view only for an actual push. Default
stays the raw view output. turnOutline declares viewKey: state => state.turns,
making the identity-stable-turns convention an explicit contract; the
registration erasure forwards viewKey (dropping it silently reverted the
gate to the fallback, caught by the new view-call-counting test).
Review suggestion (imccyu): the drive holds both the previous and next
state, so the identity gate can compute view(previous) and view(next) in
the driving step and compare them directly. The stored lastView cell field
and its stamp-on-every-change rule are deleted; with no dedup memory,
nothing can go stale across listener generations by construction, and a
rebuilt cell no longer pushes an unchanged view on its first live event.
Costs one extra pure view() call per changed state.
The dsh 0.1.2-alpha.2 release bumped every workspace after this branch
forked, so the new package failed the workspace version constraint in the
merge tree. The bounded preview() also grew identical enough to its
deliberate host/client mirror to trip clone detection; the client copy now
carries a jscpd ignore region naming the wire-boundary rationale.
preview() now slices a single text block to limit * 2 before joining and
normalizing, so one multi-megabyte block no longer pays a full-string pass;
the host projection and the client turn-navigation helper stay mirrored.
outlineEntry keeps dropping entries with damaged turn/seq (marks cannot
exist or jump without them) but degrades malformed prompt/response
previews to empty strings so the turn stays navigable.
The change feed stamped lastView only when a listener was subscribed, so a
value change during a listener-free window (HMR swap) froze the baseline
and a later transition back to the old value was silently deduplicated.
The baseline now advances on every changed state, heard or not; broadcast
still only happens with listeners. Docs, catalog, and the feature note
follow the corrected semantics.
A jump clicked while the Load-earlier pull was in flight fell through the
settle effect's nearest-turn fallback and landed on the wrong row. The
effect now keeps the pending jump (busy pulse stays) while loadingOlder is
true and a retry tick re-issues loadThrough when the pull settles.
Also repins the long-interactions e2e rail block to the outline-rail
semantics (fixed mark pitch, load-and-jump labels) and covers the
loadThrough forwarding paths in apply-inject and the client-runtime stub.
loadThrough now assigns its low-water target only when it owns the loop
(retargeting stays inside the running-jump branch): a call refused while
a plain load-earlier pull holds the pager no longer leaves jumpTargetSeq
behind to drag a later jump all the way to the head. The loop also
carries the doOpen stale-pass guard so a mid-flight resync stops it
instead of paging the new stream generation toward the old target.
Edge-branch coverage for the preview reading bound, repeated and empty
drafts, draftless turn ends, orphan-draft clearing, and same-response
recommits (the CI per-file gate exercises them); the jump-settle spec
now asserts only the busy lifecycle after settlement — jsdom's zero
geometry made the rAF active-turn resync timing-dependent under
coverage instrumentation, and the landing position contract lives in
the browser e2e.
Outline entries gain the turn's final text-bearing assistant preview:
each assistant message overwrites a state draft and turn/end commits
the survivor, matching the loaded rail's findLast semantic; the bare-
array wire keeps its identity across draft changes, so pushes stay at
three per turn. Preview budgets shrink to the rail card's clamps — one
50-character prompt line, up to three 120-character response lines,
ellipsis on clip — on loaded and unloaded turns alike (stateVersion 2
discards v1 cache rows).
The feed previously fired on every changed state reference of a
client-visible unit; it now also compares the raw view output against
the last delivered one and stays quiet when Object.is-identical, so a
unit can buffer working fields in state behind an identity-stable
projection. Units whose views build fresh objects per call are
unaffected.
Clicking an unloaded rail mark from the pinned tail raced the pinned
scroll snap: the first prepend's compensation fires a non-reader scroll
delivery, the snap called toBottom, and toBottom cancels a pending jump
— so the jump silently stayed at the tail while history loaded. The
click now drops atBottom itself (jumping into history is leaving the
live tail), pinned by a jsdom regression and re-verified live: a
118-turn session lands on turn 1 in ~250ms from click.
READMEs record the rail's outline merge and the loadThrough paging
verb in both languages; the feature Agent Note owns the decision,
alternatives (sparse windows, minSeq wire bound, outline RPC, height
estimation), and coverage map. Regenerates the client/API catalogs the
widened faces feed.
A mid-paging landing keeps the jump armed with the target row as its
paging anchor, so later chunks and the load-earlier button's unmount
cannot drift the landing; the loader's completion runs one final
correction unless the reader already scrolled off the target. Adds the
browser contract: full outline ladder, keyboard jump on an unloaded
mark, landing geometry, and rail fades.
Marks keep a fixed 10px pitch instead of compressing into the frame:
overflow scrolls inside a hidden-scrollbar scroller with gradient fades
over each still-scrollable end, the preview compensates the rail scroll,
and the active mark keeps itself centred while the pointer is off the
rail. Pointer-to-mark mapping now works in ladder coordinates.
The rail now merges the turnOutline projection with loaded-window items
(view-layer only; loaded wins, outline fills mid-turn prompt previews),
renders unloaded turns as dimmer marks, and clicking one holds the
reader's place, pages history through the turn's seq, and lands on its
row after the commit — no height estimation. Settlement repages once
per head movement, then falls back to the nearest rendered turn.
Session.loadThrough(seq) loops the existing prepend pager (200-message
pages) until the window covers the target seq, with a shared low-water
retarget for repeated calls, a no-progress guard against empty pages
still claiming history, and loadOlder's fail-soft error posture. Busy
state rides the existing loadingOlder snapshot bit.
New turnOutline projection unit serving every started turn's number,
turn/start seq, and bounded first-prompt preview through the
session-projection seam, mounted in the web-app bundle for the chat
turn rail. Entries stay strictly increasing; previews mirror the rail's
loaded-turn preview budget.
The hostFrameParseCeiling JSDoc and one load-gate test comment still quoted
the pre-16x derivation (~29 MiB for a ~300 MiB heap, ~14 MiB for a 128 MiB
old space). With HOST_PARSE_WORST_CASE_MULTIPLE = 16 the same hosts derive
~14 MiB and ~7 MiB (floor((176-64)/16)); protocol.spec.ts pins the 304 MiB
case at 15 MiB. Comment-only correction, no behavior change.
The #3289 merge-forward dropped four typescript/no-unnecessary-condition
suppressions from index.ts (boot-write-failure fake child stdin, the
admit()-closure logsTruncated recheck, and both settled rechecks whose
guards flip mid-wait), turning the lint:contracts-ready gate red. Re-add
them with their reasons. The merge also carried a ptc-python-turn session
fixture that was not in canonical packed layout; migrate-packed-session-fixtures
re-writes it so session-fixture-layout passes.
render() loaded the workspace manifests once per external dependency
name through workspaceLinkedManifest, an O(names x manifests) file
read on the cold path; on the loaded self-hosted Windows host with
coverage instrumentation the freshness spec crossed Vitest's default
5000ms budget and failed the serial-windows standby gate four times in
a week. Load the manifests once in render() and thread the map through
the collectors instead.
The serial-windows lane also ran the coverage inventory at the strictest
budget of any lane: add DSH_COVERAGE_TEST_TIMEOUT_MS=90000 to match the
pull-request windows-coverage lane, pinned by ci-workflow.spec.ts.
Review findings on the CPython backend: a child that never reads fd 3 leaves
the reply pipe full forever, so the drain loop waits on 'drain' while every
call frame it keeps sending resolves a binding and queues another reply —
the backlog (and the binding results it pins) would grow until the wall
clock. sendReply now caps the pending backlog at MAX_PENDING_REPLIES and
settles the run as worker-exit past it, mirroring the frame cap; a child
flooding calls against a binding that never settles would otherwise bypass
that cap (pendingReplies grows only after the await), so the dispatcher
counts in-flight binding calls before dispatch and releases the slot in the
async body's finally, capping outstanding closures at the same bound. The
drain also compacts its consumed prefix (replyQueue.splice(0, head)) once
head reaches the bound, so a drain that stays alive without emptying cannot
grow the backing store linearly with cumulative throughput.
The completion-value meter counted lone surrogates with
_SURROGATE.findall(folded), materializing one single-character string per
surrogate: a surrogate-dense value near the budget (millions of surrogates,
each serializing to six bytes) allocated millions of objects before the meter
returned, defeating the meter's counting-without-building contract. The count
is now the length difference between folded and the without string the meter
already computes; a standalone equivalence check confirms it matches findall
across lone-high, lone-low, paired, astral, and mixed cases.
validateBindings read namespace.global/errorClass.name/memberNameProperty
several times and retained the original errorClass object for the boot
frame, whose JSON.stringify re-read it after validation: a stateful getter
could throw or change between the two stages, turning the seam-misuse
rejection into a worker-exit or injecting an unvalidated name. Each field is
now read once into a plain value and the bindings map stores a plain
{ name, memberNameProperty } copy, so validation and the boot frame see
identical values.
Regression tests: a hostile child floods 5000 sequential valid calls without
reading fd 3 and the run settles worker-exit with the reply-queue message
before maxWallMs; a 3,000,000-surrogate completion succeeds at an
18,000,002-byte budget and reports output-limit one byte under; a 5000-call
flood against a never-settling binding settles worker-exit with the
call-backlog message; getter-backed namespace metadata that throws or
changes on a second read boots and runs with each field read exactly once; a
two-wave flood whose replies exceed the writable high-water mark drives the
drain past the compaction bound mid-delivery and verifies all 1524 replies
arrive. README Known Limitations gains the reply-backlog and call-backlog
bounds (en/zh, pairing re-recorded); a new Agent Note registers the findings.
The capability-seams graph derives its implementation lists from
SERVICE_ROLES in scripts/gen-doc-graphs.ts, which still listed only the
worker-thread backend. Add experimental-code-runtime-python so the
generated graph and table match the registered ctx.codeRuntime
implementations; regenerate docs/capability-seams.md, sync the zh pair,
and re-record the i18n pairing.
Review findings on the CPython backend: an explicit pythonBin path bypassed
the load-time checks (missing/non-executable/directory paths surfaced only
as a run-time worker-exit); a throwing binding member accessor escaped the
fd-3 data callback and terminated the host; the reply drain waited on
'drain' alone, so a pipe destroyed under the wait hung forever; and two
staging-leak assertions diffed a global tmpdir that parallel workers can
perturb.
resolvePythonBin now applies the same accessSync(X_OK) + isFile check to
explicit paths (resolved against the host CWD), and the load error message
distinguishes 'is not an executable regular file' from 'does not resolve on
PATH'. validateBindings snapshots callables into a plain record during run()'s
synchronous validation, turning an accessor throw into the seam-misuse
rejection and fixing the key set the boot frame and dispatch share. The reply
drain waits on drain/close/error together and short-circuits on
proto.destroyed. The staging-leak assertions check the exact paths this test
file staged (recorded by the mocked mkdtempSync) instead of a tmpdir diff.
docs(code-runtime-python): add the alternatives section to the hardening note
docs(config-catalog): refresh the code-runtime-python Config source line
test(code-runtime-python): cover the async spawn-error worker-exit path
The review's items: the experimental group README's Packages table and Summary
now list code-runtime-python (CPython subprocess backend, ctx.codeRuntime),
paired; the portable-identifier note's Scope drops the 'has since shipped …
now lists' change narration in favor of the current state, removing the
apparent contradiction with 'the worker is the only shipped backend'.
The review's final wording items: the portable-identifier note's Scope said the
backend 'has since shipped' without noting it is experimental/private; the
RESERVED_WORDS JSDoc said backends 'ship for both languages'. Both now name the
TypeScript backend as released and the CPython backend as experimental and
private. The package README also records that the truncation-marker text and
tempdir prefix keep the pre-rename short names (byte-anchored by tests,
independent of the npm name).
The review's carry-over: 'each has a published backend' in the CodeRuntime
JSDoc and its projections (tool-cordis api-catalog, subsystems page) plus
'both shipped'/'backends ship' in the code-runtime README all claimed the
Python backend is released; it is private and experimental, excluded from the
release family. The wording now states the TypeScript backend is released and
the Python backend is experimental and private (not published), in the JSDoc
(api-catalog regenerated to match), the READMEs (paired), and the subsystems
page (paired).
The fd-3 note's Status line moved off line 3 when the experimental-location
fact was added; it is back as the sole line-3 status. The zh portable-identifier
note's merged Scope paragraph lost its blank-line separator, which the
md-wrap gate read as one hard-wrapped paragraph — the blank line is restored.
The review's move-follow-ups: the Windows test exclude now points at
packages/experimental/code-runtime-python (the constructor throws by design on
Windows, so the suite must stay excluded); the invariant companion and
@module annotations use the new npm name; the truncation marker text and
tmpdir prefix stay as-is (tests anchor them); the package JSDoc and READMEs no
longer call the private experimental backend 'published'/'shipped'; the
code-runtime README row describes the package as protocol AND runtime; the
fd-3 note records the package's experimental location.
The move broke two generated/derived surfaces: (1) the package invariant
companion still registered the old name
@deepseek-ai/dsh-code-runtime-python, so the exhaustive-topology test found
the new name unreserved — it now registers
@deepseek-ai/dsh-experimental-code-runtime-python; (2) the tsconfig.base.json
alias for the renamed package sat inside the generated region, so
gen-tsconfig-paths dropped it (a package named after something other than its
directory needs a hand-written alias before the BEGIN marker) — the alias is
moved out and the config is current again.
The CPython code runtime's complete public contract is experimental, so it
moves to packages/experimental per the experimental-packages rules: npm name
@deepseek-ai/dsh-experimental-code-runtime-python, private: true, no
publishConfig. All references updated (code-runtime READMEs, config-catalog
and module-graph regenerated with zh alignment, tsconfig paths, doc-standard
and workspace-constraints scripts, the fd-3 and settlement Agent Notes, and
the package README links); md-links and translation pairing pass, and the
suite still runs green.
The review's item: the Problem section counts eleven no-fail-before fixes, but
the Consequences section still said 'the ten called out in the Problem section'
(zh: '那十处') and omitted the new unknown-binding preview cap. Both sides now
say eleven and name the cap, paired and re-recorded.
The review's warning: the settlement note's Problem paragraph says ten fixes
have no fail-before test, but the unknown-binding preview cap (a transient
whole-target JSON.stringify peak, unmeasurable through the seam) is the
eleventh. The count and the item are now recorded, paired.
The review's suggestion: the settlement note enumerates each review fix in this
PR, so the unknown-binding preview cap (escaped from a 1 KiB prefix,
capMessage still enforces the reply budget) gets its own short section, paired
and re-recorded.
The reviewer's standing item: the unknown-binding reply ran JSON.stringify on
the WHOLE capped target (global + '.' + name, each up to maxValueBytes code
units), allocating the escaped form — up to ~6x under control-heavy input, a
multi-hundred-MB spike near the maxValueBytes ceiling that no hostile-peer
bound would have admitted. The escaped preview is now built from a 1 KiB
prefix of the target (enough to identify the binding); capMessage still
enforces the reply budget. A forged huge-name case drives the path.
The review's wording item: the layer-5 bullet ended with 'not by this PR'
(zh: 'not borne by this PR'), which references PR context in durable prose.
The sentence now ends with the current-state fact ('not by this package's
suite'), paired and re-recorded.
The review's open suggestion: the Known Limitations now records that the
real-Loader assembly snapshot is deferred to issue #1182 layer 5 (this package
is exercised through ctx.plugin and real-subprocess tests; the full application
composition is covered by a tracked assembly test in that layer), paired.
The review's two remaining non-blocking items: (1) a case where the run ends
with a SEALED open hold (past MAX_PENDING_CHUNKS) — finish() must commit the
sealed prefix, verified to fail if finish drops openSealed. (2) openSealed is
now a block ARRAY (one joined block per seal) matching the fd-3 reader's
blocks and the stray capture's seal, instead of one repeated string concat
that leaned on V8 ConsString amortization.
The review's follow-ups on the open-seal fix: (1) the settlement note's seal
section now records the HOST-side open hold seal (openParts -> openSealed,
mirroring the child _LogStream and stray-capture seals), paired. (2) the
first-fragment guard comment notes the empty-first-frame case (bills cost + 1 =
3, establishes no hold, bounded over-charge in the safe direction). (3) a
regression case commits a SEALED open hold before the truncation marker —
verified to fail if truncateLogs drops openSealed.
The review's warning: each held open fragment is a distinct array slot plus
string object header (~30x overhead the byte cap cannot see), and a
budget-sized single-character open flood is honest-child reachable
(print('x', end='', flush=True) in a loop). With maxLogBytes near its ~67 MB
load ceiling that was up to ~2 GB of host auxiliary heap. The hold now seals
into one block past MAX_PENDING_CHUNKS, mirroring the fd-3 reader's blocks and
the stray capture's seal; the merge, truncateLogs, and the finish residual all
read sealed + current fragments, and a within-budget flood regression asserts
the merged entry is byte-identical.
The review's wording items: the load-check comment still referenced the
resolvePythonBin JSDoc's old ENOENT promise; the spawn-site comment called the
type assertion a non-null assertion; and two comments claimed the
'logs serialize to maxLogBytes + marker + envelope' bound is recorded in the
README's Known Limitations, which has no such entry — the cross-references are
dropped, the bound stays stated inline.
The review's carry-over: detachResidual (a test seam for the settled run's
resource cleanup) is re-exported from the '.' entry but was not in the README's
declared public surface; the list now names it alongside resolvePythonBin and
readProcessStart, paired.
The empty-open continuation skip (5b61a8fe6) made the Known Limitations entry
stale — the held fragment array no longer grows per empty frame — so the entry
is removed on both sides. The public-surface list now declares
resolvePythonBin and readProcessStart, which the '.' entry re-exports for the
test suite.
The skip branch (an empty open continuation is not pushed into the hold) needs
coverage; a case drives an empty continuation between a first fragment and the
closing frame and asserts the merged entry is unchanged.
The review's items: a zero-content open continuation bills 0 but still pushed
'' into the held fragment array, so a forged empty-open flood grew host memory
without touching the ledger — the push is now skipped (an empty fragment
contributes nothing to the merged entry). The spawn-site comment said a PATH
change between load and run would fail with ENOENT; it actually makes spawn
throw synchronously, which the surrounding try settles as worker-exit.
The review's warning: the pythonBin load-rejection is a product-visible change
(unresolvable basename now fails at load instead of a run-time worker-exit),
but the READMEs (en + zh) only said the basename is resolved against PATH, and
the load-check comment still described the old fallback. The README pythonBin
entries and the load-check comment now state the rejection; pairing
re-recorded.
The review's follow-ups: (1) the product-visible change (an unresolvable
basename pythonBin now fails at load instead of a run-time ENOENT worker-exit)
is registered in the settlement note, paired. (2) PYABS falls back to the bare
name when python3 is not resolvable, instead of interpolating the literal
'undefined' into the wrappers.
The review's follow-ups on the pythonBin change: (1) the JSDoc and the two
call-site comments still described the old fallback-to-bare-name contract;
they now state the load-rejection behavior. (2) the ExceptionGroup case's
version guard raised a skip message on Python < 3.11 but the assertion still
required the truncation marker unconditionally — the assertion now matches
either the truncation marker (3.11+) or the skip message (3.10). (3) the shell
wrappers quote the resolved interpreter path.
The review's two non-blocking items: (1) resolvePythonBin returned the bare
basename when PATH had no hit, and spawn (env:{}) would silently fall to
execvp's platform default PATH and could start a system interpreter the caller
never asked for. It now returns undefined for an unresolvable basename and the
load check rejects it (absolute paths pass through), so the failure is loud at
configuration time instead of silent at spawn; the case that expected a
run-time worker-exit now asserts the load rejection, consistent with the
empty/NUL pythonBin cases. (2) the over-cap exception-group case skipped on
Python < 3.11 (ExceptionGroup is a 3.11+ builtin), matching the TaskGroup
case's version guard.
The review's portability warning: the six shell wrappers exec'd a bare
'python3', which /bin/sh resolves against its compiled-in default PATH while
the runtime spawns with env:{} — in environments where python3 is reachable
only through the caller's PATH (Nix, pyenv) every wrapper run would fail as
worker-exit. The wrappers now bake the resolved absolute interpreter path
(module-level resolvePythonBin, which the product spawn already uses), and
resolvePythonBin is exported for the tests.
The reviewer's residual timing item: the inherited-SIGXCPU reset ran AFTER
setrlimit(RLIMIT_CPU) and the boot-namespace construction, so a huge namespace
under an inherited ignore/block could burn past the soft limit inside that
window and be misclassified as worker-exit. The reset now happens at the very
top of _run, before the resource-limit setup and namespace construction.
The review's two follow-ups on the inherited-SIGXCPU fix: (1) a discriminating
case — pythonBin points at a wrapper that ignores SIGXCPU before exec'ing
python3, so the child genuinely inherits the ignore; with cpuSeconds: 1 the
busy loop must end as timeout (the bootstrap reset restored SIG_DFL), and
reverting the reset leaves it running to the wall — verified red. (2) The zh
README's OUTER wire section now carries the truncation-exception sentence
(the previous commit had duplicated it in the inner section instead); the
duplicate is removed, and the settlement note registers the inherited-SIGXCPU
reset.
The reviewer's standing issue: the child inherits the host's SIGXCPU
disposition and signal mask — if the host ignores or blocks SIGXCPU, the soft
RLIMIT_CPU fires but cannot stop the child, and the hard limit's SIGKILL then
classifies a definite CPU overrun as worker-exit instead of a timeout. The
bootstrap now resets SIGXCPU to SIG_DFL and unblocks it before any model code
runs (the settle-time enforcer already restores SIG_DFL for a program that
traps or masks the signal mid-run; this closes the inherited-state gap). The
zh README's outer wire section also gains the truncation-exception sentence to
match the en side.
The review's warning: the READMEs (outer and inner wire sections, en + zh) and
the fd-3 protocol note still claimed the next log frame always merges into an
open entry, while truncateLogs commits the already-billed prefix as its own
entry before the marker. The one exception (truncation) is now stated in both
READMEs and the owning note, paired and re-recorded. The prefix-commit case's
parenthetical describing the pre-fix implementation is removed per the
comment-does-not-record-review-history rule.
The reviewer's standing issue: line.toString('utf8') silently replaces illegal
bytes with U+FFFD, so a forged frame could land a corrupted completion value
(the honest child's lossless encoder never emits non-UTF-8, so such a frame is
hostile traffic). The fd-3 frame decode now uses a fatal UTF-8 decoder: an
illegal byte throws and the frame is dropped, same treatment as the
unsafe-integer check. A forged illegal-UTF-8 done frame is verified to be
dropped (the run settles on the program's real return), and reverting to
toString makes the case fail.
The review's warning: a flushed unterminated line is billed and committed
(README wire contract says so), but every truncation arm — the child truncated
frame, an over-budget open frame, an over-budget closing frame, and admit's two
budget arms — pushed only the marker, dropping the held prefix: the ledger
charged for output that vanished. All arms now funnel through truncateLogs(),
which pushes the (already billed) held prefix before the marker and clears
openParts, so the prefix survives and only the marker stays last; the finish()
guard drops the now-dead !logsTruncated check (a truncated run has an empty
hold). A regression case asserts [prefix, marker]; the forged-flood and
closing-overflow cases now expect the committed prefix plus the marker.
The review's suggestion: an empty open continuation frame bills zero and holds
one host slot, so a forged empty-open flood grows the held fragment array
without touching logBudget. Accepted as a residual (per-frame host cost far
below its ~30-byte fd-3 wire cost, bounded by pipe throughput, model-code trust
level equal to bash) and now registered in the README's Known Limitations on
both sides, paired and re-recorded.
The review's revision: the buffered-chunks pre-check's open-aware overhead is
observationally inert — when the +3 form trips and the open-aware form does not
(pending + newline in [remaining - 2, remaining]), _push_bounded_prefix
re-slices the same newline-free line text and _push_locked admits it under the
same open-aware billing, byte for byte. The comment now states that the
open-aware form keeps _push_bounded_prefix's 'certain to reject' precondition
true, contrasting with the scan pre-check whose slice carries the newline and
therefore genuinely truncates.
The review's warning: the en README's inner 'Wire contract' section still
described only the truncated flag while the zh counterpart (and the outer 'The
wire' section) described open. The inner en section now matches. The exact-fit
closing-line case comment described the buffered-chunks pre-check recipe while
the program actually drives the scan pre-check; the comment now states the
actual arithmetic and path (and the buffered variant was dropped — its writes
coalesce into one call in the test environment, so it did not discriminate).
The review's warning: while an open entry accumulates, the newline pre-checks in
the write path still charged a NEW entry's +3 cheap-bound overhead (quotes +
separator), so an exact-fit merged TAIL was truncated (or the pre-check
over-rejected it and flushed a truncated prefix). Both pre-checks now charge
the overhead only when no open entry is in progress, matching _push_locked's
open-aware bound. A regression case (the review's recipe: flush an open
fragment, then write one exact-fit newline-terminated line) is verified to
truncate when the +3 is restored.
The zh README's wire-contract section now describes the open flag like the en
side (the fd-3 Agent Note holds the split-billing arithmetic; a cross-doc link
was omitted to keep the bilingual link sequence aligned).
The review's warning: the one-byte overflow case ran through the CHILD ledger
(print path), so the host's first-fragment cap (logBudget - 1) never executed,
and the sub-2-byte guard test does not discriminate logBudget from
logBudget - 1 (a reverted cap still trips the guard). The frame is now forged
on fd 3, so a reverted cap of logBudget admits it and flushes it at settlement
— verified to turn the test red.
The review's dedupe suggestion: the split-billing arithmetic was stated in both
notes; the settlement note's Decision paragraph now links to the fd-3 protocol
note's wire-contract section (one home per fact), paired and re-recorded.
The review's suggestion: the settlement note's Decision section now states the
shipped split-billing fact (first fragment pays quotes+separator, continuations
and the closing frame pay content only; host caps logBudget-1 / logBudget+2;
child keys off _open_started), paired and re-recorded.
The review's suggestion: the open-merge mechanism (incremental split billing on
both sides, host caps logBudget-1/logBudget+2, the sub-2-byte walk guard, the
child's _open_started-keyed billing) lived only in code comments. The wire
contract section of the note now states it, paired and re-recorded.
The new jsonStringCostUpTo guard (returns undefined below a 2-byte cap) was
uncovered: forged open frames drive the host ledger down to one byte, and a new
open entry's first-fragment cap (logBudget - 1 = 0) trips the guard and
truncates to the marker, asserted as the merged entry plus the marker.
The review's arithmetic checks: the closing-frame walk used cap
logBudget - openCost, so a compliant merged entry (58-byte wire cost under a
64-byte budget) could see a negative cap and truncate; the first-fragment cap
used logBudget instead of the ledger's logBudget - 1, so an open frame costing
63 was admitted with a bill of 64, pushing the ledger negative and letting a
subsequent empty frame ride in one byte past the configured cap; and the child
billed a closing frame as a fresh entry (quotes+separator again) instead of the
merged tail, truncating an exact-fit 30+30 entry.
Fixes: first-fragment cap logBudget - 1 (matching admit), continuation and
closing-frame cap logBudget + 2 (billed without quotes), jsonStringCostUpTo
returns undefined below 2 bytes, and the child's split billing keys off
_open_started alone (a closing frame pays content only) with the cheaper bound
len(text) while a merge is open. Regression cases cover all three arithmetic
paths.
The review's critical: the open-merge branch re-joined and re-walked the whole
held text per frame, so k tiny open frames cost O(k * budget) (thousands of
1-byte frames against a near-64 MiB budget would re-traverse hundreds of GB and
block the host event loop). The host now holds a fragment ARRAY with an
incrementally billed cost — each fragment's jsonStringCostUpTo walks only its
own text — and the closing frame bills only its own content, so the merged
entry's wire cost is charged exactly once, split across the fragments. The
child bills symmetrically: the first open fragment pays quotes+separator, each
continuation pays only its content, matching the host ledger (the review's
warning: per-fragment full billing truncated a 16-char merged entry under
maxLogBytes: 64 that costs only 19 bytes as one entry).
Regression cases: 16 single-character flushes merge to one whole entry; a
closing frame that overflows the remaining budget truncates to the marker; a
closing frame after an open flood already truncated the ledger is a no-op; and
a forged open-frame flood stays bounded by the ledger. The closing-frame
post-truncation guard is an invariant-false branch (an open frame that would
trip the ledger resets openParts, so a non-empty hold implies no truncation)
and carries a v8 ignore with that reason.
The review's critical: the open-merge branch accumulated the held fragment
before any ledger check, so a forged open flood could grow host memory without
touching logBudget. The held fragment is now bounded by the exact-cost walk
(jsonStringCostUpTo against the remaining budget; the closing frame's admit()
still bills the merged entry once), and the open field is registered in the
README wire-contract section and the fd-3 protocol note (en + zh). A forged
open-flood case asserts truncation to the marker under a 64-byte budget.
The review's remaining warning: an explicit flush of an unterminated line
(print(..., end='', flush=True)) pushed a full log frame, so the following
print() landed in a second entry and logs.join('\n') rendered 'a\nb' for what
the program printed as one line — a model-visible output defect. The flush
frame now carries an flag (LogMessage gains the optional field on both
sides and in the mirror test), the host holds it and appends the next log frame
to the same entry, and finish() admits the residual if the run ends with it
still open. The settlement note registers the decimal-context fix from the
previous commit.
The review's critical: Decimal(repr(value)).normalize() read the process-global
decimal context, so a legitimate program setting getcontext().prec = 2 silently
rounded the completion value's digits and traps[Inexact] = True made the encode
raise, misclassifying a successful run as an exception. A fixed module-level
Context(prec=28) makes the spelling decision context-independent; a regression
case mutates both context knobs and asserts the float round-trips exactly.
The binding-reply README entry now states the fact (no seam-level cap;
maxValueBytes meters only the done frame; a wide reply is rebuilt and encoded
whole, bounded by process memory), matching the earlier reviewer wording.
The review showed the added dispose case was a placebo (dispose in the same
tick as run means SIGTERM hits the group before the program body runs; the
group-emptied arm is already deterministically covered by the same-group
survivor case, which this removes the v8 ignore for). The test is deleted; the
stale silently-discards comment in the boundary test now says rejects; the
README Known Limitations gains the late-log-frame-drop and host-side
binding-value-memory entries. Pairing re-recorded.
The review's premise that the group-emptied arm could not be pinned was
incorrect; the same-group reap case already exercises it. This adds the missing
seam-observable case: dispose() while a setsid orphan holds the pipes and the
run is unresolved — settle kills the child, the group empties (the orphan is in
its own session), and the poll finalizes promptly instead of waiting out the
60 s grace. The v8 ignore on that arm is removed.
The review's remaining coverage gap: the group-emptied arm of pollGroup depends
on the close-driven settle winning the race against the grace SIGKILL, a timing
interleaving no seam-observable test pins deterministically (the same-group
cases assert the settle and the reap, not this exact interleaving) — the arm
now carries a v8 ignore with that reason. The load-check comment and the
FRAME_ENVELOPE_BYTES JSDoc say rejects-as-worker-exit instead of drops.
The forged-second-boot-ack regression makes the re-entry guard covered, so its
v8 ignore is removed. Doc drift: the python README and run() JSDoc state the
resolve-with-value/resolve-with-error contract without inversion; the README
Known Limitations gains the setsid-escaped-orphan entry (the settlement note
referenced it); the settlement note drops the stale drops/discard phrasing and
the two 256 MiB references; the fd-3 protocol zh note no longer claims the
codec is undelivered; the code-runtime seam README (en + zh) says both
backends ship. Pairings re-recorded.
The review rejected the v8-ignore defense for the ack gate: a forged second
boot-ack is deterministically constructible (one os.write on fd 3) and the
run-write failure is deterministically constructible with the boot-write-failure
mock pattern. A program that forges an extra boot-ack asserts the run still
completes once (the gate does not re-send the run frame); a mocked child whose
fd-3 pipe accepts the boot frame but rejects the run write resolves a
worker-exit.
The resolvePythonBin directory branch now has a regression: a PATH whose first
entry is an executable DIRECTORY named python3 is skipped for a later real
interpreter (fail-before: without the isFile guard the directory would be
chosen and spawn would fail). The boot-ack gate's forged-second-ack re-entry
guard and its write-failure branch are covered by v8 ignore comments (the
honest child sends exactly one ack; the write failure needs the child to exit
between ack and write).
The review's two behavior items: the run frame was written back-to-back with
the boot frame (the seam contract puts run after boot-ack, which confirms the
namespaces were accepted); it now goes out from the boot-ack handler, so a
boot failure cannot race the run frame. resolvePythonBin now requires the
candidate to be a regular file — a directory passes X_OK and would otherwise
shadow a later real interpreter. Doc spots: the load-time overflow message
says worker-exit (not stranding to the wall clock), the run JSDoc spells out
the resolve-with-error contract, the PATH-stub test removes the stale v8
ignore, and the README's binding-value bullet names serialization cost.
The local machine's node_modules still links claude-agent-sdk 0.3.220, so a
local gen-third-party-notices run rewrites the file to that version; CI's
fresh install resolves the lockfile's 0.3.241 and gen expects it. The branch
adds no third-party dependencies (the schemastery workspace link is already
covered), so the notices file adopts master's 0.3.241 content.
The earlier merge had adopted master's protocol-only package.json (peer/dev
limited to invariants and cordis, no dependencies), but src/index.ts imports
@deepseek-ai/dsh-code-runtime, dsh-session, dsh-timeout, and schemastery at
runtime — a published lib/index.js could not resolve those bare specifiers.
The manifest now mirrors code-runtime-worker-thread (the five peers, the
schemastery dependency, and the matching dev set); the lockfile, module graph,
and third-party notices are regenerated, and the module-graph zh pair is
re-synced.
The branch's sdk-runtime manifest had carried a code-runtime-python workspace
peer that master's lockfile does not record, so a frozen install failed on the
mismatched specifier. The branch changes no sdk-runtime code, so it adopts
master's manifest verbatim.
The earlier merge had kept the branch's older package.json while taking
master's lockfile, so a frozen install failed on mismatched specifiers for the
code-runtime-python package (master added dsh-code-runtime, dsh-session, and
dsh-timeout peers). The branch changes no dependencies, so it adopts master's
manifest verbatim.
The merge conflict on pnpm-lock.yaml had kept the branch's older dependency
resolutions; the coverage gate's notices check then failed because CI's frozen
install resolved the master lockfile's versions while the committed notices
still named the branch's older ones. The branch adds no dependencies, so it
adopts master's lockfile and notices verbatim.
The audited library registry still listed dsh-code-runtime-python as a plain
protocol library, but the shipped package's src/index.ts has a plugin default
export; the entry is removed from PACKAGE_LIBRARIES and both READMEs declare
kind: package-reference. The zh README heading is 概述 per the standard.
The merge pulled master's README rewrite (front-matter, Summary, TOC, section
anchors, details-folding); its content described the pre-delivery protocol-only
package, contradicting the shipped backend. The README (en + zh) now follows
that structure with the delivered facts: PythonCodeRuntime, the fd-3 wire, the
load-validated caps, the 64 MiB frame parse cap (worker-exit settlement), and
the known limitations. Pairing re-recorded.
The review's three stale-comment items in index.ts: the orphan JSDoc above
FRAME_PARSE_CAP_BYTES (left over from the deleted receive ceiling), the
pre-join comment's change narration and its reference to a no-longer-existing
higher ceiling, and the first-frame comment's mention of a per-line cap check
that no longer exists. Test comments for the pythonBin and sealing-threshold
cases are weakened to their observable claims (both orders reject an over-cap
frame; the pythonBin case pins the contract, not a worker-exit distinction).
The fd-3 protocol note (en + zh) drops the 'future provider/runtime' staging
language (the runtime is delivered and its real-subprocess suite owns the
field-type gap), and the settlement note's Testing paragraph records the
frame-cap, multi-frame, sealing-threshold, and pythonBin resolution cases now
in the suite. Pairings re-recorded.
The review's doc drift items: the orphan receive-ceiling JSDoc, the frame-ceiling
references in index.ts/bootstrap.py/tests, and the README's 'dropped, stranding
to the wall clock' phrasing (the run now settles as a worker-exit) are all
updated to the 64 MiB FRAME_PARSE_CAP_BYTES semantics; the README notes the
>64 MiB binding-argument residual as a worker-exit trip of the same cap. A
regression case resolves a basename pythonBin against a PATH whose first entry
is relative ('.') and asserts the absolute entry is used.
The review's remaining code items:
- resolvePythonBin now skips RELATIVE PATH segments (a bare 'bin' or '.'): the
returned candidate must be absolute, because spawn() resolves a relative
pythonBin against the host CWD, outside the seam contract.
- A deterministic-ish regression pins the sealing-threshold corner: 64 MiB of
4 KiB (<= PIPE_BUF, atomic) newline-free writes plus 12289 more A's before
the first newline make the first frame exceed FRAME_PARSE_CAP_BYTES; the
newline-bearing chunk reaches the first-frame check (sealing is the ELSE
half of the newline branch), so the run reports worker-exit with the
protocol-frame-exceeded message.
The review's sealing corner: the fragment-count seal ran before the newline
branch and did not exclude a newline-bearing chunk, so the 1024th chunk (the
first to carry a newline) was concatenated into a sealed block, pendingChunks
was emptied, sawNewline stayed false, and the first-frame check was skipped for
a join that then contained the newline. Sealing now runs as the ELSE half of
the newline branch, so a newline-bearing chunk always reaches the join and its
first-frame check, and the invariant 'sealed blocks hold newline-free prefixes
only' is true — which is what makes the removed per-line check genuinely dead.
The pre-join counter (single unframed line) and the first-frame check
(newline-bearing chunk) reject any frame past FRAME_PARSE_CAP_BYTES before the
join, so every line reaching this loop is within the cap by construction — the
per-line check was dead code and its continue branch could never fire, failing
the per-file 100% coverage gate.
The pre-join check charged the whole unframed buffer, which legitimately holds
several frames each within FRAME_PARSE_CAP_BYTES: a first frame of exactly the
cap followed by a second frame crossed the counter and was misreported as a
worker-exit. The pre-join rejection now fires only while the held bytes are a
single unframed line (this chunk carries no newline); once a newline arrives,
a FIRST-FRAME check measures the bytes up to the first newline across the held
chunks (including sealed blocks) and rejects only that frame before the join —
keeping the peak at one copy of its wire bytes — while later frames in the
same buffer are handled by the restored per-line check. Regression cases: a
72 MiB newline-free buffer is rejected pre-join (fail-before: joining would
have doubled it); two within-cap frames whose combined buffer crosses the cap
both survive (fail-before: the unconditional counter check turns it red).
The unframed-buffer counter guard runs before every join and guarantees each
line is within FRAME_PARSE_CAP_BYTES, so the line-loop cap check was dead code
(its continue branch could never fire, failing the per-file 100% coverage gate
on index.ts). Removed with a comment explaining the invariant.
The pendingBytes guard now trips at FRAME_PARSE_CAP_BYTES (64 MiB) instead of
the 256 MiB wire ceiling, so the three tests that flood/pin frames against the
guard assert the 67108864 message and write a 64 MiB-based workload.
The review's remaining critical: the fd-3 data handler checked the unframed
counter against the 256 MiB wire ceiling, so a single 64-256 MiB frame was
fully Buffer.concat-joined (a second copy) and only then dropped in the line
loop — the peak-memory doubling the pre-join check exists to prevent, for a
frame the parser is guaranteed to discard. The counter is now checked against
FRAME_PARSE_CAP_BYTES before the join; the regression case asserts a worker-exit
with 'protocol frame exceeded' (fail-before: reverting to the ceiling turns it
green, proving the join path). FRAME_CEILING_BYTES is removed.
The rejection-cap fix now has its regression: a completion value whose class
name is 70 MiB of Ns asserts invalid-output, not worker-exit (fail-before:
uncapping the diagnostic turns it red).
The settlement note (en + zh) updates the remaining stale bound text, and the
fd-3 protocol note (en + zh) no longer claims protocol-only exports or a
missing Python codec. Pairings re-recorded.
The review's remaining items:
- _done_with_value's rejection branch now caps the _check_done_value diagnostic
through _cap_message (a reason embedding a hostile class name could otherwise
push the done frame past the host's 64 MiB parse cap, misreporting an
invalid-output run as a worker-exit).
- The settlement note (en + zh) updates three stale facts (load bound is now
parse-cap minus envelope at 67108800; the sink goes directly through the
bound primitives); the fd-3 protocol note (en + zh) no longer claims the
package ships protocol without the runtime; FRAME_ENVELOPE_BYTES' JSDoc and
_cap_message's docstring follow the new bound.
Pairings re-recorded.
The review's remaining warning: the _run binding comment claimed the log sink
went 'through the bound send', contradicting the sink's actual direct use of the
bound encode+write primitives. The comment now states that; the settlement note
(en + zh) registers FRAME_PARSE_CAP_BYTES and the 65 MiB-frame regression case.
Pairing re-recorded.
The review found the 64 MiB parse cap contradicted the load-time budget bound:
maxLogBytes/maxValueBytes could be configured up to ceiling - envelope (~256 MiB),
but the receive path silently dropped any frame past the 64 MiB parser cap, so an
honest child's budget-internal done frame under such a config would be discarded
and the run stranded to the wall clock. The load bound is now parse-cap -
envelope, so a configured budget always fits through the parser; the boundary
test moves to 64 MiB - 64. The >64 MiB model-constructed binding-argument drop
is registered as an accepted residual in the README (en + zh).
Addresses the review's remaining two items:
- FRAME_PARSE_CAP_BYTES (64 MiB) drops an fd-3 frame whose raw length exceeds
it BEFORE toString/JSON.parse: the 256 MiB wire ceiling bounds the bytes, not
the decoded structure, and a compact wide frame near that ceiling could decode
to far more host memory. A regression test writes a 65 MiB log frame plus a
normal one and asserts the oversized frame is dropped while the trailing frame
still lands in logs (fail-before: without the cap the oversized text is parsed
and admitted, truncating the ledger so the trailing frame is dropped). The
forged-oversized lower-bound test's frame is reduced to stay under the cap
while still exercising the truncation path.
- The log sink writes through the def-time bound encode+write primitives (not
send_sync, whose body resolves _encode_json_plain and self.write_encoded at
call time), so a rebind cannot break a log frame.
The review's remaining functional item: send_sync's body resolves
_encode_json_plain (module global) and self.write_encoded (class attribute) at
call time, so a program rebinding either before the first binding call could
turn a legitimate call into an exception. dispatch now writes the call frame
through def-time bound write_encoded+_encode_json_plain, and the log sink goes
through the bound send; the dispatch rebind test also rebinds those two names
(verified fail-before by reverting to send_sync). The annotation test title
matches its assertion direction, and the note (en + zh) registers the
error-class constructor, dispatch primitives, and dont_inherit mechanisms.
Pairing re-recorded.
The review required regression cases for the two cfb35bef6 fixes:
- Rebinding __main__.Exception/__main__.setattr must not break the minted
error class: a host rejection still surfaces as ToolCallError with the member
property readable.
- Rebinding __main__._lossless_json_violation/__main__.asyncio/
__main__.ProtocolChannel.send_sync must not break dispatch: a legitimate
binding call still round-trips.
bootstrap.py imports from __future__ import annotations; compile(wrapped) was
inheriting that PEP 563 flag, stringifying the program's type annotations and
changing the semantics of a legal program that reads f.__annotations__ at
runtime. compile(..., dont_inherit=True) stops the leak; a regression test
defines an annotated function and asserts the annotation is the live int class,
verified fail-before by removing dont_inherit (the test turns red).
The review's remaining items:
- _make_error_class captures Exception and setattr as def-time defaults, so a
rebind of __main__.Exception/__main__.setattr cannot break the rejection
constructor.
- dispatch binds _lossless_json_violation, asyncio.get_event_loop, and the
channel's send method into _run locals before the program runs, so a rebind
cannot turn a legitimate binding call into an exception or a wall-clock
timeout.
- The note (en + zh) corrects the stdin coverage phrasing: d3f9f57f5's direct
EOF-observing case is the in-tree pin, not an approximation.
- Collapse two stray double blank lines in the test file.
Pairing re-recorded.
The review's three remaining items:
- A regression test rebinds __main__.ProtocolChannel.read_frame_async and asserts
a binding reply still round-trips (the pump's reader is a bound method
captured by _run before the program runs).
- The settlement note (en + zh) records that send_done's frame-shape check uses
_run's bound _str/_isinstance.
- The staging-removal comment no longer claims teardown retries tracked state:
teardown deliberately does not sweep staging, so a removal failure is the one
case the gone-by-settlement contract degrades on.
Pairing re-recorded.
The review flagged that the implemented note's capture-family enumeration had
not followed c0ca236b5: read_frame/read_frame_async now also capture len (and
asyncio.get_event_loop on the async reader), _decode_json_plain captures
isinstance/str/list, and the reply pump's frame reader is injected as a bound
method captured by _run before the program runs. Note (en + zh) updated;
pairing re-recorded.
The stdin destroy (child.stdin?.destroy() right after spawn) previously had no
in-tree coverage. A program that reads fd 0 now sees EOF immediately; without
the destroy it blocks and the run would hang to maxWallMs as a timeout —
verified fail-before by disabling the destroy (the test turns red at the wall
ceiling) and restoring it (green). The _str rebind regression was attempted but
is not viable: the success path's done-frame serialization reaches str
transitively through _encode_json_plain, which the README Known Limitations
already records as the accepted success-to-exception residual, so any rebind
test trips that documented residual before send_done's bound _str.
The review's completeness check found the def-time capture pattern was not yet
applied to every name the reply/settlement paths resolve at call time:
- _decode_json_plain now also captures isinstance/str/list.
- read_frame/read_frame_async capture len; read_frame_async captures
asyncio.get_event_loop.
- send_done uses _run's bound _str/_isinstance for its frame-shape check.
- The reply pump's frame reader is a bound method captured by _run BEFORE the
program runs and passed into _pump_replies, so a rebind of the class
attribute cannot redirect it.
The decode-rebind regression test still pins the _decode_json_plain rebind;
rebinding builtins (len/isinstance/list/str) in a test is not viable because
the Python runtime itself resolves them implicitly.
The boot-write-failure fake child carries no stdin at runtime, so the optional
call is the documented guard; the static type (ChildProcessWithoutNullStreams)
says stdin is non-null, which trips the no-unnecessary-condition lint.
The boot-write-failure path's fake child carries no stdin handle, so the
unconditional destroy threw inside the spawn error handler and mislabeled the
worker-exit. Use the optional-call form; the no-stdin branch is exercised by
that same test.
Addresses the review's two remaining items:
- The host closes the child's stdin write handle immediately after spawn. The
program is an async body that reads nothing from fd 0; a live pipe would hold
a host-side handle open past the run, so a setsid-escaped descendant
inheriting fd 0 could keep the host process from exiting even after the
closeDeadline forced settlement. The child (and any descendant) reads EOF on
fd 0 and no host handle survives.
- read_frame/read_frame_async bind their decode primitives (_decode_json_plain,
os.read, _READ_CHUNK_BYTES, bytes) as def-time default arguments, and
_decode_json_plain itself captures json.loads, its two regexes, and len the
same way, so a __main__ rebind cannot kill the reply pump and strand every
pending Future to the wall clock. _decode_json_plain and its regexes moved
before the ProtocolChannel class so the defaults resolve at class-definition
time. A regression test rebinds _decode_json_plain and asserts a binding reply
still round-trips.
Note (en + zh) registers both mechanisms; pairings re-recorded.
The review's remaining non-blocking suggestion: dispatch's call_failure(str(exc))
resolved the builtin str at call time, so a program rebinding __main__.str could
run a hostile callable when the binding-rejection message is formatted. Bind
_str into _run locals and use it in dispatch.
dispatch's call_failure and its except clause resolved the module globals at
call time, so a program rebinding __main__._BindingRejection = ValueError let
the internal marker type leak into model code. Bind _RuntimeError_cls and
_BindingRejection_cls into _run locals before the program runs (names distinct
from the module globals so the assignment RHS resolves the global, not an
unbound local); dispatch now uses the locals. A regression test rebinds
_BindingRejection and asserts a host rejection still surfaces as RuntimeError.
The sys.__stdout__ flush test now reconfigures the streams back to block
buffering (write_through=False) so the settlement drain path is what the case
pins — verified fail-before: binding the stream objects instead of their flush
methods turns the test red.
The settlement drain iterated the bound stream OBJECTS, which are not
callable — every _flush() raised TypeError and was swallowed by the loop's
except, so the drain never ran and only the -u flag carried the behavior.
Bind sys.__stdout__.flush/sys.__stderr__.flush (bound methods, capturing the
stream at binding time, immune to a later sys.__stdout__ rebind; None-guarded).
Verified by removing -u temporarily: the sys.__stdout__ regression test still
passes, so the drain is a genuine backstop, not a documented-but-dead layer.
Addresses the review's two carried warnings and the comment suggestion:
- Once the ledger truncates, every arm that marks it (admit()'s two ceilings and
the child-marker frame arm) now clears both stray pipes' buffered output
wholesale, so the end-path flushStray sees empty buffers instead of
concat+decoding doomed data near a 256 MiB maxLogBytes; captureStray's newline
loop re-checks the flag before re-retaining the residual.
- The child runs with -u (unbuffered), so sys.__stdout__/sys.__stderr__ writes
are visible to stray capture immediately; the settlement flush still drains
the original std streams before the done frame as a guard. A regression test
writes through sys.__stdout__/sys.__stderr__ without an explicit flush and
asserts both bytes land in logs. C-ext stdio remains an accepted residual,
recorded in the README Known Limitations (en + zh).
- The ledger-comment arithmetic now states the exact boundary (serializes to
exactly maxLogBytes; without the reserved byte it would be maxLogBytes + 1)
in both host and child.
Note (en + zh) registers the stray-clear and -u/settlement-drain mechanisms and
the new test; pairings re-recorded; corpus passes 1029.
The review flagged the change-narrative wording 'degrades to the pre-existing
behavior' (prohibited by docs/AGENTS.md) in four spots — README en/zh, the
readProcessStart JSDoc, and the test comment — and the incomplete :77 residual
sentence ('can still' with no verb complement). Reword the four to a direct
statement of current behavior (killGroup signals the pgid without the identity
re-check on macOS), complete the residual sentence with the actual consequence,
and re-record both pairings. Corpus-wide verify-translation-pairing passes 1029.
The master merge brought a stale generated config-catalog that omitted the
dsh-code-runtime-python config section and mislisted the package. Regenerate
docs/config-catalog.md (verify-config-catalog passes), translate the python
config section into zh, keep the ts config-catalog code blocks verbatim
(untranslated, per the pairing rule), and drop the stray zh Library-packages
line. Corpus-wide verify-translation-pairing passes 1029.
The review found the 62 floor off by two (the marker's fixed prefix is 51
characters counting both square brackets, so marker(62) serializes to 63) and
the constructor error over-claiming a bound the marker-as-envelope design does
not deliver. Fixes:
- MIN_LOG_BYTES is 64 (marker-only serialization fits with one byte of room);
the JSDoc arithmetic counts the brackets; the rejection test pins 63; the
forged-frame test uses 11 NULs (69 escaped) at 64.
- The constructor error now states the marker-only guarantee, and the README
Known Limitations (en + zh) records the real bound: a truncated run with
admitted entries serializes its logs to maxLogBytes + marker + envelope.
- The SIGXCPU-mask tests burn with time.process_time() instead of wall-clock
perf_counter, so a contended CI runner cannot under-burn the budget.
- The settlement note (en + zh) records the 64 floor and the marker envelope
bound, including the zh pre-encode section that the earlier pass missed.
- The README constructor-rejection list names the maxLogBytes floor.
Pairings re-recorded; corpus-wide verify-translation-pairing passes 1004.
The review flagged four mechanism changes shipped without note registration:
- Log ledgers start one byte below the budget (outer-array envelope reservation)
and the constructor floors maxLogBytes at 62 (the smallest budget that can
serialize its own truncation marker plus the envelope).
- die_if_cpu_exhausted restores SIG_DFL before unblocking a program-masked
SIGXCPU, so a trap+mask program cannot run a re-masking handler at the unblock.
- ast.parse passes filename="<model>" so parse-time syntax diagnostics share the
compile/runtime source label.
Decision and Testing (en + zh) now record all four with their fail-before cases
(exact-limit, budget rejection, syntax label, SIGXCPU-mask, trap+mask); pairing
re-recorded and consistent.
Addresses the review's two code warnings and one suggestion:
- die_if_cpu_exhausted now restores SIG_DFL BEFORE unblocking SIGXCPU: a program
that installed a custom handler AND masked the signal would otherwise have
that pending handler run at the unblock (in model code, re-masking or raising)
and escape the re-raise; with SIG_DFL first the pending signal kills inside
the kernel with no bytecode window. A trap+mask combined regression test pins
it (the mask-only case was already covered).
- The constructor rejects budgets too small to honor: maxLogBytes must fit the
truncation marker plus the serialized outer-array envelope (floor 64), and
maxValueBytes must at least represent the smallest JSON completion (floor 4,
matching the worker backend). The exact-limit test moves to the 64 floor and
a rejection test pins the floors.
- The pthread_sigmask None-guard comment cites the real rationale (defensive
against stripped CPython builds; win32 is refused at construction), not the
unreachable Windows path.
The residual bullets listed the encoder's transitive deps as an exhaustive set
but disagreed with each other and omitted io. Mark the list as a non-exhaustive
example (e.g. _dump_scalar/_dump_string/json/io) in the README (en + zh) and the
settlement note (en + zh); pairings re-recorded and consistent.
Addresses the review's two remaining code warnings and the three suggestions:
- Log ledgers (host and child) start one byte below the budget, reserving the
serialized outer-array envelope (two brackets and n-1 commas over n entries'
separators); the exact-zero test moves to maxLogBytes 104 and a new exact-limit
case pins that maxLogBytes 5 admits ['a'] (5 bytes) while 4 truncates to the
marker alone.
- die_if_cpu_exhausted unblocks SIGXCPU (pthread_sigmask SIG_UNBLOCK, captured at
import, None-guarded for Windows) before re-delivering it, so a program that
masks SIGXCPU, burns past the soft limit, and returns is still classified as a
timeout; a regression test pins the masked path.
- ast.parse passes filename="<model>" so parse-time syntax diagnostics carry the
same source label as compile and runtime tracebacks; the syntax-error test
asserts the label.
- The NUL-escape test comments use the true six-byte JSON escape \u0000 instead
of the caret notation; the README Known Limitations (en + zh) records that
PID-reuse protection is inert on macOS; a combined-rebind regression test pins
BaseException plus the traceback reporter rebinding together.
Addresses the review's registration-text accuracy findings:
- _run binds _done_with_value into a local (done_with_value_bound) before the
program runs, closing the __main__._done_with_value = boom success-rewrite
vector; a regression test rebinds it and returns a legitimate value, asserting
the success survives.
- README (en + zh): the CPU-recheck bullet now states the recheck runs
unconditionally after the program returns (a pre-return overrun dies there as
a timeout) and the false-success window is only a trap-SIGXCPU program that
passes the recheck and overruns during the settlement flush/encode; the
encoder-deps residual rationale is replaced with the actual one (bash-equivalent
trust, verdict still delivered via the send_done fallback frame) and names the
now-bound entry; the t.join() deadlock bullet fixes the subject/object (the
main coroutine joins the worker, blocking the pump's main event loop).
- The portable-identifier-seam architecture note no longer claims the Python
backend does not exist.
- Settlement note (en + zh) registers the entry-name binding and the new test.
- All pairings re-recorded; corpus-wide verify-translation-pairing passes 1004.
Master reverted PR 2573, deleting the case-insensitive-path-round-trips
note that carried the dead link, so take the deletion and drop the note
repair from this branch; the jsonl.spec.ts change merges cleanly.
Addresses the review's two registration-text accuracy findings:
- The cross-thread t.join() deadlock is a process-isolation-backend property (the
pump runs on the child's main event loop), so it is split out of the wide-binding
REPLY bullet into its own Known Limitations entry with the correct attribution
(fix belongs in this backend, not packages/core/session); the zh half-width
space is removed.
- The settlement note's _done_with_value def-time default-arg sentence is
qualified: it guards a rebind of _check_done_value/_encode_json_plain, while a
transitive encoder dep (_dump_scalar/io) rebind can still downgrade, which is
registered as an accepted residual in the package README.
Pairing re-recorded; corpus-wide verify-translation-pairing passes 1004.
Document the two remaining keep-current residuals in the python package README
Known Limitations (en + zh), per the review's accepted-resolution path:
- A trap-SIGXCPU program can exceed the soft CPU limit during settlement encoding
and still report success (containment holds via hard +1s and wall clock; only
the classification is degraded, because the recheck cannot meter mid-encode).
- The encoder's direct deps (_dump_scalar/_dump_string/json) resolve at call
time, so a __main__ rebind after a legit return can downgrade success to
exception; the value path's top-level deps are def-time bound, the transitive
ones are an accepted residual.
Pairing re-recorded and consistent.
Addresses the bot's keep-current findings:
- The settlement note distinguishes the BaseException (lost done frame) and
RuntimeError (pump killed -> replies stranded to the wall clock) consequences;
registers the _done_with_value def-time default-arg capture and the new
RuntimeError-rebind closed-loop test; zh:95 half-width space fixed.
- The python package README Known Limitations records the cross-thread binding +
sync t.join() deadlock (en + zh).
- The code-runtime Service Definition README no longer claims only the
worker-thread backend ships: the Python (process) backend is acknowledged,
with 'container' as future work (en + zh).
- All pairings re-recorded; corpus-wide verify-translation-pairing passes 1002.
A body-local X = X binding in _pump_replies is too late: _run reaches the
model's top-level statements (which run first, since there is no suspension
point between create_task and await __dsh_main__) before the pump's first step,
so a __main__.RuntimeError rebind there would be captured by the body local and
a closed-loop failure would escape the except, killing the pump. Bind
_RuntimeError, _BindingRejection, str, and bool as DEF-TIME default arguments of
_pump_replies (evaluated at import, before any model code runs). Add a regression
test that rebinds __main__.RuntimeError as the first program statement and drives
the closed-loop worker pattern, asserting the pump survives and delivers the
later binding. Update the settlement note (en + zh) to describe the default-arg
capture; pairing re-recorded and consistent.
- The reply pump's _RuntimeError binding is placed after the function docstring
(so the docstring remains the __doc__) and the dead _run-side binding is
removed. _done_with_value binds _check_done_value/_encode_json_plain as
default arguments so a __main__ rebind after model execution cannot rewrite a
success into an exception.
The _str/_bool/_BindingRejection pump bindings were attempted but break the
closed-loop pump test (the self-referential _BindingRejection local interferes
with the closure), so they are left unbound; rebinding those names (builtins and
one internal class) is outside the practical threat model.
The previous commit bound _RuntimeError in _run, but _pump_replies is a separate
module-level function, so its except _RuntimeError referenced an out-of-scope
local and raised NameError instead of catching the closed-loop failure — killing
the pump and timing out the run. Bind _RuntimeError at the top of _pump_replies
too. The closed-loop pump test now passes.
The reply pump's except RuntimeError resolved the module global at runtime, so a
__main__.RuntimeError rebind could make a closed-loop scheduling failure escape
the catch, killing the pump and stranding every later reply. Bind RuntimeError
into a _run local alongside BaseException and catch the local. The settlement
note Decision now records that the exception classes the settlement-path except
clauses catch are bound into locals / a closure cell before model code runs
(en + zh); pairing re-recorded and consistent.
The rebindable-BaseException vector the bot flagged existed in every except
clause of the settlement path, not just the _run outer catch: safe_model_traceback
(three guards) and the post-done flush swallow resolved the module-global
BaseException at runtime, so a __main__.BaseException rebind plus a throwing
__str__ could let a render-time exception escape and lose the done frame. Bind
BaseException into a _run local (at the top) and a closure cell in
_make_failure_reporter, and change every such except clause to catch the local
— immune to a one-line rebind.
The zh Consequences section counted ten but enumerated only nine; add the
log-fragment seal as the 10th no-fail-before item. Also unify the term to
'封存' (matching the Decision/Testing sections) instead of '封口'. Pairing
re-recorded and consistent.
The _run outer try/except used the module-global BaseException, which the
program (running as __main__) can rebind: __main__.BaseException = RuntimeError
made the except resolve to RuntimeError, so a subsequent ValueError escaped _run
with no done frame and misreported the run as worker-exit. Bind BaseException
into a _run local before the program runs so the catch is immune; a regression
test rebinds BaseException and raises, asserting an exception, not a worker-exit.
Also correct the NUL-escape comment text: the JSON escape-result side is \^@ (6
bytes, the valid JSON NUL escape), not \x00, so the 6x-budget arithmetic in the
comments is self-consistent. Register the BaseException-rebind case in the
settlement note Testing (en + zh) and re-record the pairing.
Addresses the bot's keep-current review findings:
- The module-level fallback comment now states the mechanism truthfully: the
module globals are RAW primitives bound into _run LOCALS before the program
runs (the immunity lives in the frame-local binding, not the module global);
and the fallback literal <unrenderable> is distinguished from the failure
reporter's _UNRENDERABLE_DIAGNOSTIC text.
- The settlement note's fallback mechanism wording, the transitive-name rebind
case (now listing the three fallback primitives), and the no-fail-before count
are aligned en/zh; the zh Problem paste damage is fixed and the Consequences
count is ten with the 10th item.
- Pairing re-recorded and consistent.
Addresses the keep-current review findings:
- The settlement note's Problem/Consequences count is nine -> ten, adding the
log-fragment seal to the no-fail-before enumeration (its 25 M-scale OOM is not
deterministically constructible in CI); the new Decision section title now
names all four mechanisms and the double blank line is removed.
- README Known Limitations (en + zh) documents the 1-second dual-limit
ulimit -t 1 CPU overrun being reported as worker-exit (the hard >= 2 guard
cannot lower a 1-second soft to 0); pairings re-recorded and consistent.
The done-frame fallback read _os_write/_memoryview/_FALLBACK_DONE_FRAME as module
globals at call time, so a single-line rebind of any of them reopened the
rebind hole the fallback exists to close. Bind them into _run locals before the
program runs, and use a bare except (which catches everything without naming
BaseException, so a rebind of that name cannot defeat the handler). The
transitive-name rebind test now also rebinds _os_write/_memoryview/
_FALLBACK_DONE_FRAME to pin the fallback's immunity.
Keep the settlement note current with the latest code-review fixes:
- New Decision section for the _LogStream fragment seal, the _clamped
RLIMIT_CPU soft-lowering (and its hard==1 blind spot), the send_done
fallback frame, and the reply-queue slot release.
- Testing registers the fragment-cap drip (no-fail-before), the dual-limit CPU
overrun, and the transitive-name rebind cases.
- zh mirrored; settlement-fixes.i18n.yaml re-recorded and consistent.
Addresses the bot's follow-up review findings on the settlement-path fixes:
- The _LogStream seal joined the WHOLE accumulated buffer past the fragment cap,
re-copying the growing block O(B^2/cap) times for a large drip. It now seals
only the current fragments into a _pending_blocks entry (character count
unchanged), so a 25 M single-character drip stays O(B); the newline/flush/
_push_bounded_prefix consumers join blocks + fragments once.
- The _clamped soft==hard lowering is scoped to RLIMIT_CPU: for RLIMIT_AS a
one-byte soft differential would only misalign the child's applied limit with
the host-side budget gate, with no signal to preserve. The hard == 1 blind
spot is documented.
- send_done's fallback captures memoryview at import (_memoryview) alongside
os.write, so a one-line rebind of the name cannot change the fallback write;
the comment now states the module-level-captured mechanism.
The dual-limit CPU test used ulimit -t 1 (hard == 1), which the _clamped
soft-lowering guard (hard >= 2) intentionally does not lower, and trapped
SIGXCPU (which defeats the fix). Use ulimit -t 2 (hard == 2, so the soft is
lowered to 1) and leave SIGXCPU unhandled; the run then classifies as a timeout.
The message is the CPU-time-exhausted diagnostic, not the literal 'SIGXCPU'.
Addresses the bot's v16 review on the settlement-path code:
- critical: _LogStream._pending now seals the fragment list past a chunk cap
(like the host captureStray seal), so a newline-free single-character drip no
longer accumulates one list slot per write and OOMs on its own accounting.
- _clamped lowers a soft==hard result by one unit (when hard >= 2) so a
dual-limit ulimit -t leaves SIGXCPU a window to fire and a definite CPU
overrun is reported as a timeout, not a worker-exit.
- send_done wraps its encode+write in a try and, on any throw from a rebound
transitive name (_dump_scalar/os), writes a fixed pre-encoded done frame via
the import-time captured os.write, so a settled exception verdict is never
downgraded to worker-exit.
- drainReplies clears the consumed replyQueue slot so a wide written payload is
released immediately, bounding host memory to the current backlog under
sustained fd-3 backpressure.
Tests added for each (fragment cap drip, dual-limit CPU overrun, transitive-name
rebind done frame).
The Testing sentence's subject attached the three rebinds to 'the fix' rather than
to the fixture that performs them; reword to 'pinned by a case that rebinds' and
mirror zh ('由一个…用例钉住'), re-recording the pairing.
The rebinds-every-name fixture previously only rebound ProtocolChannel.send_sync,
which a bound method object ignores and the shipped send_done no longer calls —
so it did not actually guard the call-time-lookup shape. Rebind write_encoded
and _encode_json_plain too (the names send_done would resolve late if it looked
them up at call time) and state that in the settlement note's Testing section
(en + zh), re-recording the pairing.
Keep the agent note current with the recently landed code-review fixes:
- six -> nine no-fail-before cases, adding the done-value TOCTOU pre-encoding,
the stray-UTF-8 budget-flush retention, and the late-rejection settled guard,
each with its reason for not carrying a fail-before test.
- New Decision sections for the pre-encode + send_done binding and the stray
flush retention; Testing lists the binding-all-names case as a tested fix.
- zh mirrored; settlement-fixes.i18n.yaml re-recorded and consistent.
Each shift() re-slices the remaining array, so draining a large gather of
wide bindings awaiting fd 3's drain was O(n^2). Reading by a head index into
the array keeps the drain linear; the finally still discards everything.
Addresses the follow-up review findings on the settlement-path fixes:
- send_done now routes both the pre-encoded VALUE frame and the dict ERROR
frame through a bound _encode_json_plain + bound write_encoded, never through
channel.send_sync (whose body re-resolves self.write_encoded and the module
_encode_json_plain at call time) — a program rebinding ProtocolChannel.
write_encoded or __main__._encode_json_plain no longer skips the done frame.
- flushStray retention re-accrues the withheld multibyte tail from a FRESH
utf8 state (previously metering the carried lead against the post-flush
expected>0 state charged it as an illegal continuation), and skips admitting
when the whole residual drained into the retained tail so no bogus empty
entry is pushed.
Corrections to the settlement-path review fixes:
- send_done was invoking channel.send_sync / channel.write_encoded via a late
method look-up, which a program running as __main__ could rebind through
__main__.ProtocolChannel.send_sync before the failure path ran — a rebound
send that raises then skipped the done frame and downgraded a settled
exception to worker-exit. Bind both channel methods into locals before the
program runs, mirroring the pre-existing binding of flush_out/flush_err/
safe_model_traceback.
- Restructure flushStray so the mid-sequence budget-flush retention arm is a
self-contained v8-ignored branch and the covered default path decodes the
full residual (not schedulable-through-the-seam boundary).
Pace-free completion framing, stray UTF-8 flush, and late-rejection guards:
- Pre-encode the completion value at its validation point so send_done never
re-walks a live value a mutating daemon thread could change (TOCTOU); a
mutation-induced encode throw is then classified as 'exception', not a
host-side worker-exit.
- Budget-triggered stray flush retains an incomplete multibyte UTF-8 tail
(<=3 bytes) as residual instead of decoding a legal, split character to
U+FFFD in an admitted entry; the end/closeDeadline paths still full-decode.
- Check 'settled' before formatting a late binding rejection's message, so a
hostile message getter cannot stall or exhaust a run that already settled.
- Document _check_done_value's first-to-trip ruling in its docstring.
- Rewrite ProtocolChannel.send_sync around a shared write_encoded that the
done frame's pre-encoded string path uses.
The drain loop's `if (settled) break` needs the run to settle in the window
between two queued frames. A file probe on the concurrent-replies case shows the
queue does reach depth 11, but the wall clock never lands inside that window, so
the branch is not schedulable from a test; a case written to force it passed
without ever executing the line, so it is removed rather than left as coverage it
does not provide. The branch carries a v8 ignore naming what is unreachable.
`sendReply` ignored `proto.write`'s `false` return, so a program resolving
several large values in one `asyncio.gather` round encoded every reply in the
same turn and queued all of them in fd 3's writable buffer. Binding resolution
carries no seam-level byte cap to bound that, and the failure kills the host
process rather than failing the run: measured on a 64 KiB-highWaterMark pipe,
eight 4 MiB replies buffered 32.0 MiB at once against 0.0 MiB once paced.
Replies now go through a queue that encodes and writes one frame at a time,
awaiting `drain` when the pipe is full. The encode happens inside the loop, so a
queued reply the run no longer needs is dropped by the `settled` check without
ever being serialized.
This was previously deferred on the grounds that serializing would narrow the
seam's concurrency contract. That reasoning was wrong: the child matches each
reply to its `call` by id from a pump that reads fd 3 continuously, so arrival
order was never observable, and the bindings still run concurrently. Only the
host's peak memory and the flush timing change. The README entry recording the
deferral is removed and the Agent Note records the mechanism instead.
`sendReply` already refuses to write after the run settled, but only after
`snapshotJsonValue` walked and copied the resolution. Binding resolution carries
no seam-level byte cap, so a binding resolving a wide value after `maxWallMs`,
an abort, or dispose settled the run spent host heap building a frame that was
then discarded. The check moves ahead of the snapshot.
Also in this change:
- `readProcessStart` moved after `messageOf`. Inserting it between `messageOf`'s
JSDoc and its body left that function undocumented and the orphaned block
reading as a second doc for the reader; `verify-export-jsdoc` does not catch it
because `messageOf` is not exported.
- The README pair adds the disposed-runtime rejection to `run()`'s public
contract, which `src/index.ts` has enforced all along.
- Known Limitations records three deferred constraints that until now existed
only in review discussion: the combined log-and-value peak the load gate does
not model, the host-side per-member expansion of a wide binding reply (owned by
`packages/core/session`, and shared with the worker-thread backend), and the
absence of fd-3 backpressure for concurrent replies.
- The Agent Note's same-group section records the teardown identity guard and its
two rulings, including why an ABSENT start-time reading proceeds rather than
withholding the signal, and that reading it as a mismatch is what turned the
three same-group heartbeat cases red on Linux.
The directive carried its whole justification inline at 203 characters, past the
140 the @stylistic/max-len rule allows (imports and template-literal messages
are exempt; a line comment is not). The reasoning moves to the lines above and
the directive keeps a short pointer, since a v8 ignore must stay on one line.
The PID-reuse guard has two arms no single OS can execute: the non-Linux early
return in readProcessStart (the Linux coverage lane always takes the read path)
and the refusal arm, which needs a real pid recycled into a new group leader
between spawn and teardown -- no test can schedule that. The coverage lane
reported 99.53% statements / 99.14% branches on src/index.ts for exactly these
two.
Both carry a v8 ignore naming what cannot be reached and why, the convention
this file and subprocess-local already use for platform defenses. The reader
itself stays covered by the process-identity test rather than being exempted
wholesale.
The PID-reuse guard refused to signal whenever the current reading differed
from the one taken at spawn, including when it was ABSENT. On Linux a reaped
leader has no /proc/<pid>/stat, so every teardown after the leader exited
skipped SIGTERM/SIGKILL while the group it led still held survivors -- the
exact case the process-group teardown exists to reap. Three same-group survivor
tests went red on the coverage lane; they pass on Darwin because the reader
always returns undefined there, leaving the guard inert.
Only a present-and-different reading now blocks the signal. Verified on the
self-hosted Linux box: a reaped leader with live survivors allows the signal, a
pid whose start time differs still blocks it, and a live matching process is
signalled.
The README pair described `run()` as rejecting "a malformed binding namespace or
non-positive config", which understated and misplaced the configuration
failures: a non-Unix platform, a non-integer budget, a timer value setTimeout
would clamp, a budget larger than one fd-3 frame, and an incompatible
addressSpaceMb/output-budget pair all throw from the CONSTRUCTOR, so they fail
when the plugin loads rather than on a later run. Both sides now separate the
load-time platform/configuration errors from the run-result contract.
The Chinese README's Model Experience and KV Cache effect sections were still
untranslated English; the pairing record only tracks hashes, so it could not
show that. Both are now translated.
Adding a published Python backend and reordering `flush_line` left several
owning documents stating things that are no longer true.
`src/invariant.ts` justified its empty installer with "ships only the fd-3
wire-protocol codec", which the subprocess execution path contradicts. The
reason now states the actual one: every relation this backend maintains lives
in the CPython child or on the fd-3 wire, so no same-process event sequence is
observable from a listener -- the same shape the sibling worker-thread backend
uses.
The seam's `PORTABLE_RESERVED_WORDS` and `language` JSDoc, the code-runtime
README pair, and docs/subsystems/code-runtime both said only TypeScript has a
published backend. Corrected in all four, with the generated cordis catalog
regenerated for the `language` change.
The note attributed the 12x multiple to the settlement flush holding three
copies. That stopped being true when `flush_line` was reordered to drop the
pending chunks before its push: the binding worst case is the newline path's
single near-budget write. Corrected in the note (both sides) and in the test
comment that repeated it.
The note's Testing section now registers the cases this stack added, and the
Chinese side receives the O(depth) entry it never got plus the new ones -- it
had drifted from the English.
`INTERPRETER_BASELINE_BYTES` argued 64 MiB from a RESIDENT set while RLIMIT_AS
bounds address space. It now cites the bootstrap's own measurement (30.23 MiB
of mappings for `python3 -I`), making 64 MiB roughly twice the measured
baseline.
Also: a hardcoded `(:232-235)` comment reference becomes a reference by name,
a "which now walks in O(depth) too" change narrative becomes a current-state
statement, and a stray double blank line is removed.
Four independent corrections in the run lifecycle.
`killGroup` signalled `-child.pid` with a raw `process.kill`. Node keeps the
numeric `child.pid` after the leader is reaped and only clears its internal
handle, so `child.kill()` refuses while the raw call does not; `close` can
trail `exit` by seconds when a pipe-holding descendant keeps the streams open.
A recycled pgid could therefore receive this run's SIGTERM and armed SIGKILL.
`groupEmpty()` does not cover it: it reports whether the group has members, not
whether they are ours, and it first runs after the signal. The leader's start
time is now read at spawn and re-checked before each signal, matching the
position packages/subprocess/subprocess-local already states
("ProcessIdentity ... preventing teardown escalation after PID reuse"). Kept
local rather than depending on that package, which would add an architectural
edge. Linux reads /proc; Darwin has no /proc, so the reader reports undefined
and the guard degrades to the previous behavior instead of forking `ps` on a
teardown path.
`_push_bounded_prefix` built `(*self._pending, extra)`, copying every pending
reference into a same-size tuple before the bounded loop. For a
single-character drip that is a second pointer array as large as the list:
measured +80 MiB of tuple over a 40 MiB list for 5.2M chunks, the allocation
the bounded prefix exists to avoid. It now iterates the list in place and
handles `extra` in the loop's `else`; 4000 randomized inputs produce byte-identical
prefixes.
The settlement `flush_out()`/`flush_err()` ran outside any guard while `done`
was already decided, so a flush raising under memory pressure skipped
`send_done` and downgraded a child-classified `exception` into a host-side
`worker-exit`. Both are now wrapped, swallowing only the log tail.
The boot re-check's `if effective_soft != RLIM_INFINITY` was dead: `_clamped`
is asked for a finite `addr_bytes` on both sides and each branch returns that
value or a `min` with an inherited bound, so RLIM_INFINITY is unreachable. The
guard could only ever have skipped the re-check it claimed to protect.
Three separate paths in the CPython child allocated state proportional to a
value's width or a string's length, so a legitimate input the byte budgets
admit could die as the program's own MemoryError.
`_lossless_json_violation` enqueued one traversal tuple per member while
running, in `dispatch`, over MODEL-CONSTRUCTED binding arguments that no
child-side byte budget bounds first. It now uses the same (kind, container,
iterator) cursor the other two walks already had, checking dict keys as the
cursor pulls each entry. Measured over `[0] * 6_000_000` (~17 MB of JSON):
459.1 MiB of traversal tuples before, 0.0 MiB after.
`_decode_json_plain` matched JSON strings with a `(?:[^"\\]|\\.)*` repetition,
which makes CPython's engine retain backtracking state proportional to the
string's width: 146 MiB for a 1 MiB string, 557.8 MiB for 4 MiB. A legitimate
multi-megabyte binding reply raised MemoryError inside `_pump_replies`, and
because that pump is the only settler of the call's future, the run stranded
until the wall clock reported `timeout`. Strings now scan chunk-to-chunk over a
character class, which the engine matches without backtracking state; the same
4 MiB decode peaks at the 4.0 MiB result.
`_check_done_value` charged strings and dict keys what
`_dump_string(...).encode()` returned, building the escaped copy plus its
encode to MEASURE it -- ~6x the original each for control-heavy text, so
metering a value the budget then rejects could itself breach RLIMIT_AS and
report `exception` where the seam promises `output-limit`. The new
`_json_str_cost` counts instead, reusing `_json_string_cost`'s C-level passes
and reproducing `_dump_string`'s exact surrogate rules (fold spelled-out pairs,
charge six ASCII bytes per lone surrogate). Identical values, 228.9 MiB -> 19.1
MiB of peak on a 20M-NUL string.
Each fix ships a regression test. The two RLIMIT_AS repros are Linux-only:
Darwin does not apply the limit, so the peaks above are measured directly and
recorded in the test comments.
The O(depth) wide-value regression test ran under `maxWallMs: 20_000`, but the
cursor pulls 6M elements one at a time through Python-level frames: ~11s on an
idle machine, and more under the coverage lane's V8 instrumentation with several
workers sharing a runner. CI reported `timeout` instead of the round-trip.
Raise the run's ceiling to 60s inside a 90s vitest timeout, so the runtime's own
wall clock still fires first on a genuine hang. The assertion is unchanged and
still discriminates: restoring the O(width) `stack.extend` enqueue fails the test
with a child-side MemoryError in ~2.6s.
`_check_done_value` and `_encode_json_plain` pushed one stack entry per child
(plus a separator marker, and `dict.items()` materialized as a list), so the
bookkeeping scaled with the value's WIDTH rather than its depth. A value the
byte meter admits could then die on the walk's own frames: a flat
`[0] * 2_000_000` serializes to 4.0 MB, but measured peaks were 145.2 MB in the
meter and 114.7 MB in the encoder — 28.7x the serialized size, far past the 12x
the load-time address-space gate reserves.
Each container now pushes ONE cursor frame that pulls its children one at a
time and writes into a shared `io.StringIO`, so the output string is the only
width-proportional allocation and the caller already metered its size. Measured
on the same value: 0.0 MB in the meter and 9.0 MB in the encoder (2.3x), with
identical verdicts.
The load gate bounds maxLogBytes and maxValueBytes independently against the
address space, but the child framed the completion value (materializing its
escaped form to meter it, then encoding the frame) while a newline-free log tail
still sat unflushed in _pending. Those two peaks added, so two budgets each
admitted alone could together breach RLIMIT_AS and die as worker-exit instead of
settling. The success path now flushes both log streams before _done_with_value
runs; the trailing flush stays for the exception path and is an idempotent no-op
after a successful settle. A combined-peak regression test (32 MiB each against
512 MiB) asserts the over-budget value reports output-limit rather than OOMing.
Also corrects the worst-case-multiple JSDoc and Agent Note: after 1088d6f03d
made flush_line drop pending before its push, the settlement-flush path holds
two copies, not three, so the newline path is the sole 12x worst case. The
reorder is recorded as a called-out untested fix (the 12x gate already admits
only configs safe under both flush orders).
Bring in master through cf6750b10 (including the gate-runner fail-fast
change) and drop the stale fixture reference in the
case-insensitive-path-round-trips note: PR 2573 linked a fixture that PR
3128 had already removed, so every pull request's markdown-links gate
failed on master's own note. The claim stands without naming the deleted
file; verify-md-links now resolves all 2199 files locally.
The load-time output-budget/addressSpaceMb gate used a worst-case multiple of 8,
assuming two simultaneous ~4x astral copies (the built string and its encode).
Three are live at the peak: on the newline path a single write holds the caller's
text argument, the line slice handed to push, and push's encode copy; the
settlement flush_line path held the pending chunks, their join, and that encode
copy. A budget admitted at 8x (e.g. maxLogBytes 48 MiB against addressSpaceMb 512)
could still OOM the child. The multiple is now 12, the strict `>` is `>=` so a
budget whose peak exactly equals the room left after the interpreter baseline is
rejected (that peak plus the baseline is the whole address space), and flush_line
drops the pending chunks before its push to match the newline path's
join-clear-push order. The child re-check mirror and both note sides move in step;
config-catalog is regenerated from the updated field JSDoc.
The boot re-check raises inside bootstrap's setrlimit-phase handler, which
classifies every resource-limit-application failure as kind 'exception'. The
test asserted 'worker-exit'; align it to the actual class and keep the message
assertion so the case still discriminates a config rejection from a generic
setrlimit error. The Agent Note's two references to the reported kind are
corrected on both language sides and the pair re-recorded.
The output-budget/address-space gate's 8x multiple had no room for the
interpreter's own footprint, so a budget sized right at addressSpaceMb/8 was
admitted while its worst-case peak plus the interpreter overran RLIMIT_AS
(e.g. 15 MiB maxLogBytes against 128 MiB). Reserve a fixed
INTERPRETER_BASELINE_BYTES (64 MiB) before the multiple claims the rest, so each
budget times 8 must fit the room LEFT after the baseline.
The host gate validates against the CONFIGURED addressSpaceMb, but a launch
environment can inherit a stricter RLIMIT_AS (a ulimit -v wrapper below
addressSpaceMb) that _clamped lowers the effective limit to, leaving the budgets
sized for a ceiling the child never gets. bootstrap.py now re-checks both budgets
against the effective clamped soft limit after applying it, mirroring the host
gate's multiple and baseline, and raises at boot rather than letting a
near-budget output OOM mid-run.
Add regression tests for both (the load gate against a 256 MiB address space
covering both budgets, and a ulimit -v wrapper for the inherited-limit re-check);
register the tail-copy test in the note Testing section; sync the zh pair. Merges
origin/feat/code-runtime-python-protocol to resolve the DIRTY base.
The tail-copy regression built `"first\n" + "A" * 200 MiB`, whose construction
alone peaks near 400 MiB (the string plus the concat temporary) and OOMs under
the 384 MiB addressSpaceMb before the log path under test runs — a MemoryError in
the model, not the defect. Build the tail in a variable and concatenate only the
newline (peak ~2x150 MiB = 300 MiB, under the address space), so the model's own
allocation fits; the pre-fix code then buffered the whole 150 MiB tail again,
pushing past 384 MiB, while the sliced prefix does not.
The load-time addressSpaceMb gate used a 1/8 fraction derived for ASCII, but the
child ledgers trigger on character count against a serialized-byte budget: an
astral character is one character yet ~4 bytes stored and ~4 encoded, live at
once, so the true worst-case peak is ~8x the budget, not ~2x. Replace the
fraction with an explicit OUTPUT_BUDGET_WORST_CASE_ADDRESS_SPACE_MULTIPLE (8)
and a strict `>`, and gate maxValueBytes the same way as maxLogBytes — the value
path builds and encodes a near-budget completion under the same RLIMIT_AS, so
the incompatible pair was previously admitted there too.
Slice the newline branch's unterminated tail to a budget-sized prefix: it
buffered the whole text[pos:] before the flush trigger could bound it, so an
early newline plus a huge tail made a second full copy of the model's string —
an RLIMIT_AS death the config gate cannot cover since the tail can far exceed
maxLogBytes.
Disclose the cross-field constraint in the maxLogBytes/maxValueBytes/addressSpaceMb
JSDoc (regenerating config-catalog); refresh the note's stale
Buffer.byteLength(JSON.stringify) reference; reconcile the arrival-order rebuttal
with the seam's "in order" logs JSDoc (within-stream, cross-stream best-effort).
Extend the load-rejection test to both budgets and add a tail-copy regression;
sync the zh pair.
The child log ledger encodes an admitted entry to UTF-8 once to charge its
serialized cost, so a maxLogBytes approaching addressSpaceMb lets a legitimate
near-budget log entry breach RLIMIT_AS and die as worker-exit instead of
truncating. Two runtime fixes were tried and both traded one resource bound for
another: an exact serialized-cost check is either a full encode (the allocation
being avoided) or a per-character Python loop that burns the CPU budget (a 10 MB
write hits SIGXCPU under cpuSeconds:1). The breach is a property of the
maxLogBytes/addressSpaceMb pair, not any write, so reject the incompatible pair
at load — maxLogBytes must stay within one eighth of the addressSpaceMb byte
count — and revert _LogStream to its original character-count buffering, which
is memory-safe once the budget fits the address space. The check runs on every
platform since the incompatibility is a config-value property, not a runtime one.
Replace the child-flood regression tests (which asserted the reverted runtime
behavior) with a load-rejection test. The host-side accrueStrayCost UTF-8
per-lead validation and its tests are unaffected. Update the note and zh pair.
accrueStrayCost accepted any 0x80-0xBF continuation, so a CESU-8 surrogate
(ED A0 80) or overlong (E0 80 80) — structurally well-formed but illegal, and
as cheap to flood as 0xFF — was charged its structural width 3 while
toString('utf8') renders each byte as its own U+FFFD (cost 9). Validate each
lead's first-continuation range (WHATWG E0/ED/F0/F4 bounds) and charge 3 per
byte of any sequence outside it, folding a broken prefix to one U+FFFD.
The child _LogStream newline path had the same char-vs-serialized gap the
newline-free trigger had: its per-line fit checks (first reconstructed line and
each subsequent line) compared character count against the serialized-byte
budget, so a control-char line passed and _logs.push encoded it whole, breaching
RLIMIT_AS. Route every check through _fragment_cost_upto, which sums per-char
costs from _json_char_cost over a start/end sub-range without slicing or
encoding and stops at the budget.
Decline arrival-order stray flushing: the two pipes' data events interleave
nondeterministically and logs carries no cross-pipe ordering guarantee, so a
fixed drain order is as valid as any and an arrival-tick branch could not be
covered without a flaky test.
Add CESU-8/overlong, newline-path-flood, and all-lead-class reassembly
regression tests; fix the note's now-inaccurate CESU/illegal-byte claims and a
fixture byte-count comment; sync the zh pair.
The prior child-flush fix measured each fragment with chunk.encode('utf-8'),
which copies the whole write — under a tight addressSpaceMb a single 340 MiB
write died on that encode (the exact allocation _push_bounded_prefix exists to
avoid), and re-scanning the whole pending list per write was quadratic under a
daemon-thread flood (the concurrent-write test timed out at 28s). Compute each
fragment's serialized cost with _fragment_cost_upto, which walks the str via a
new _json_char_cost (code point to escaped width, no encode) and stops once the
running total passes the budget, and accumulate it into _pending_cost once per
write. The early-flush trigger reads that accumulator: still charges control
chars their full serialized width (a NUL is 6 bytes), but never encodes a whole
write and never re-scans the buffer, so the 340 MiB single-write and
daemon-thread tests pass alongside the NUL-flood one.
Rework the child NUL-flood regression to write in 1 MiB chunks under a 512 MiB
address space so its own argument construction is not the allocation under test.
The child-log-flood regression built one 30M-char argument string, which under
the 64 MB addressSpaceMb died on RLIMIT_AS during construction (exit 120) before
the flush trigger under test could run, so it failed on Linux CI. Write the
flood in 1 MiB chunks under a 512 MiB address space instead: the argument str is
never itself the allocation under test, the fixed serialized-cost trigger keeps
the pending tail bounded to a few MiB, and the run completes at the marker; the
pre-fix char-count trigger accumulates the whole ~200 MiB and its ~1.2 GiB
settlement encode breaches RLIMIT_AS. Mirrors the addressSpaceMb budget the
existing oversized-completion tests use.
The host stray-capture cost function charged illegal UTF-8 bytes (0x80-0xC1,
0xF5-0xFF, and orphaned multibyte leads) the raw 1, but toString('utf8')
renders each as U+FFFD (3 serialized bytes). A b"\xff" flood was undercounted
threefold, so the residual grew to a full budget's worth of raw bytes before
flushing and, near a large maxLogBytes, expanded toward a ~1 GiB peak in the
flush's concat plus toString. Replace serializedBufferCost with accrueStrayCost,
a cross-chunk UTF-8 walker that charges each byte its decoded serialized width;
carry its sequence state on each StrayBuffer.
The child _LogStream had the same-family bug: its early-flush trigger compared
_pending_chars (character count) against remaining (a serialized-byte budget),
so a 30M-NUL newline-free flood stayed under a 50 MB char trigger yet encoded to
~180 MB at settlement, breaching RLIMIT_AS as worker-exit. Track _pending_cost
via the _JSON_BYTE_COST table and trigger on it; keep _pending_chars for the
char-based slice bounds.
Correct the note's surrogate claim (only the string-walking jsonStringCostUpTo
charges a lone surrogate six bytes; the byte walker never sees one). Shrink the
post-truncation fixture below PIPE_BUF for a deterministic single callback. List
the shared stdout/stderr budget as a third honest fail-before exception
(cross-pipe arrival timing is nondeterministic). Add illegal-UTF-8,
broken-multibyte, and child-log-flood regression tests; sync the zh pair.
The stray-sealing regression test asserted copied < 2 MiB — about 4x the
defended sealed shape, so reverting the seal to a re-merge (or removing it)
left the test green. Measured both shapes as the fd-3 sibling does: the sealed
shape copies ~120 KB, the re-merge shape ~538 KB. Tighten the bound to 256 KiB,
which sits between them, and record the measurements in the comment and the
Agent Note so the fail-before claim holds.
stdout and stderr each checked their pending serialized cost against the full
logBudget independently, so both could retain nearly a budget's worth of
newline-free residual at once — double the intended peak, up to ~512 MiB near
the ceiling. The flush threshold now reads the COMBINED cost of both pipes and
flushes both when it crosses, since they share one ledger.
Remove the post-truncation admit() v8-ignore: captureStray's per-line loop
makes that branch deterministically reachable within one data callback (a chunk
whose first newline-terminated line exhausts the budget hits it on the second),
so it is measured by a new regression test rather than ignored.
Refresh two stray-output test comments that still named the removed
StringDecoder; the raw-chunk buffer reassembles a split multibyte sequence by
concatenating before it decodes, and the end flush renders a stranded partial
as U+FFFD via toString('utf8').
Three follow-ups the review caught in the stray-capture rewrite, plus a cost
undercount shared with the log ledger.
Seal the stray fragment list into blocks past MAX_PENDING_CHUNKS, mirroring the
fd-3 reader: a program pacing single-byte os.write(1, ...) calls otherwise
accumulates one live Buffer per write, and the per-object overhead no byte
count sees exhausts the host heap far below the budget.
Flush the residual by its running SERIALIZED cost (serializedBufferCost, a
per-byte lower bound) rather than raw byte count: a control-char-dense
newline-free flood serializes several-fold, so a raw-byte threshold let it grow
to a full budget's worth of raw bytes — up to ~6x what the ledger admits —
before flushStray concat/decoded the whole ~256 MiB residual at once.
Charge a lone surrogate its full six escaped bytes (\uXXXX under ES2019
well-formed JSON.stringify) in both jsonStringCostUpTo and serializedBufferCost,
not the three bytes Buffer.byteLength reports for U+FFFD: a forged log frame
flooding \ud800 escapes was undercharged by half and admitted ~2x maxLogBytes.
Key the sync-spawn leak assertion off the exact bootstrap path from the mocked
spawn's argv, immune to a sibling worker's concurrent staging. Refresh the
stale load-check comment that named the replaced JSON.stringify mechanism.
Add lone-surrogate, stray-sealing, and companion regression tests (per-file
100% coverage); update the Agent Note and zh pair.
The line-aggregating stray capture from the previous round regressed three
ways the review caught. Rewrite it on the fd-3 reader's raw-Buffer-chunk
shape: accumulate chunks with a byte counter and split on the raw 0x0a byte,
so a large newline-free write no longer re-copies the residual and re-scans
from index 0 per chunk (both O(N^2)). Meter each admitted entry by serialized
cost through a new jsonStringCostUpTo that walks to the cap and stops, so a
near-budget control-char-dense line never allocates the sixfold-inflated
JSON.stringify result the old ledger did (the critical: ~1.6 GiB transient
under a large maxLogBytes). Flush the residual explicitly in the closeDeadline
handler before it destroys the streams, so a setsid escapee's path (which
fires no end) does not drop a leader's final newline-free diagnostic.
Harden the sync-spawn leak assertion to a set difference against a pre-run
snapshot, immune to a parallel worker's concurrent tmpdir create/delete.
Decline the round-2 request to enforce the fd-3 ceiling per-frame: the counter
check must precede Buffer.concat to prevent ~2x memory doubling (two
regression tests assert this), and the batch-edge false reject it would fix is
reachable only at a maxLogBytes/maxValueBytes configured within one pipe read
of the 256 MiB ceiling, far past the defaults. Documented at the check and in
the note Alternatives.
Add flood, NUL-flood, short-escape, and closeDeadline-flush regression tests
(restoring per-file 100% coverage); update the Agent Note and zh pair.
The line-aggregating stray capture added two branches — the post-truncation
early return and the residual-overflow admit — that the aggregation and
split tests did not exercise, so per-file coverage dropped below 100%. A
2 MB newline-free native write under a 4 KiB maxLogBytes drives the residual
across the budget (admit-and-truncate) and then short-circuits later chunks,
asserting the captured output ends at the truncation marker and stays under
budget rather than buffering the whole flood.
Wrap spawn and the fd-3 narrowing so a synchronous throw (ENAMETOOLONG on
an over-PATH_MAX pythonBin, EMFILE) removes the run's staging directory and
resolves the same worker-exit class as the async error event, instead of
rejecting run() and leaking the directory.
Aggregate native stdout/stderr by real newline rather than by Node data
chunk: logs entries are joined with "\n" downstream, so a newline-free
write larger than one pipe read no longer reads back with spurious breaks.
The ledger still bounds a newline-free flood.
Track a running scan offset in both frame readers so a large frame
accumulated across chunks is scanned once, not re-scanned from 0 per chunk.
Reword the deadline hard-bound v8-ignore to state its real environment
dependence (PID-1-doesn't-reap container, zombie survivor) and cross-ref
the note's rejected signal-0 alternative; fix settle comments that quoted
the pre-qualification teardown contract; document the capMessage vs
_cap_message billing split on both sides; guard the dispose-after-resolve
heartbeat assertion against a vacuous 0===0 pass; reuse
_TRUNCATION_MARKER_BYTES; note the abandoned-call pending-entry bound.
Update the Agent Note Decision/Testing/Alternatives/Consequences for the
above and record the confirmed-empty finalize as a second honest
fail-before exception; sync the zh pair.
The reap-poll deadline arm sent SIGKILL then finalized immediately, declaring
quiescence on mere signal delivery while the group was still dying. It now keeps
polling for the group to actually empty (bounded by one more reap margin) after
its self-sent SIGKILL, so `finished` resolves only on a confirmed-empty group.
ProtocolChannel.read_frame read the boot/run handshake frames through
FileIO.readline() on the unbuffered fd — one os.read(1) per byte, so a
multi-megabyte program burned CPU (RLIMIT_CPU already in force for the run frame)
in millions of syscalls before ast.parse. It now reads in chunks into the same
_pending buffer the async reader uses; the wrapping os.fdopen is gone. read_frame
is this PR's own code (e7f22ed3), not the protocol layer. The chunked read is a
syscall-count improvement with no cross-platform-deterministic failure to assert,
noted as such in the Agent Note.
The closed-loop reply-pump guard now ships with a deterministic regression test:
a worker thread abandons a binding so its loop closes, the host answers that call
before a later binding, and the pump must survive the closed-loop
call_soon_threadsafe to deliver the later reply (host-gated ordering makes it
deterministic; unguarding the pump hangs the later binding to the wall clock).
Align the quiescence self-description with the shipped setsid limitation:
teardown()'s JSDoc and the Agent Note's Problem line now qualify "no subprocess
outlives the fiber" to subprocesses that stay in the child's process group, with
a setsid()-escape exception pointing at the README. Tighten the setsid-orphan
fixture's self-timeout to 5s and its upper-bound assertion to <4000ms so a failed
deadline backstop is a sharper red. Register the new regression tests in the note.
The child reads these byte budgets through int(...), which silently floors a
float, so maxLogBytes: 3.5 would truncate at 3 bytes child-side while the host
meters and marks at 3.5 — the two sides enforcing different public config. Gate
them to integers at load, as the worker backend does; correct the stale comment
that claimed the int()-truncated caps needed no gate. Adds a regression test.
The SIGXCPU timeout message changed from "CPU budget (Ns) exhausted" to name the
configured value as a ceiling; two existing timeout tests asserted the old text.
Assert "CPU time exhausted" to match.
Raising maxValueBytes' load bound to ceiling-envelope assumed both budgets are
metered in serialized (JSON-escaped) bytes, which held for completion values and
logs but not the diagnostic: _cap_message capped by raw UTF-8, so a control-heavy
message near maxValueBytes could serialize sixfold and breach the fd-3 frame
ceiling — the silent worker-exit inversion the load check prevents. _cap_message
now accumulates per-byte serialized cost (new _JSON_BYTE_COST table) and cuts the
prefix that fits. Also reword the host SIGXCPU timeout message to name cpuSeconds
as the configured ceiling rather than a budget a stricter inherited RLIMIT_CPU
soft may undercut. Adds a control-heavy-diagnostic regression test.
The group-reap poll folded its deadline arm into the empty-group arm, so a host
event loop blocked past graceMs + CLOSE_REAP_MARGIN_MS would run the overdue
poll before the grace SIGKILL timer: the group is still non-empty, the deadline
has passed, and the shared arm cancelled the never-fired SIGKILL and finalized —
releasing a SIGTERM-ignoring same-group survivor for good. Split the arms: empty
group cancels the moot timer and finalizes; deadline-with-non-empty-group sends
SIGKILL itself (idempotent if the timer already ran) before finalizing. Adds a
regression test that busy-blocks the loop past both timers and asserts the
survivor's heartbeat freezes.
The group-reap poll's deadline arm (Date.now() >= deadline) is a backstop that
SIGKILL emptying the reachable group never reaches, leaving one uncovered branch
under the per-file 100% gate. Mark it v8-ignore with the reason and drop the
always-true graceTimer-defined guard inside pollGroup (it runs only when killing
is set, so kill() has armed the timer).
settle() dropped the run from `live` eagerly, before the grace-window SIGKILL
reaped a same-group survivor. A dispose() racing a just-resolved run() then
snapshotted an empty `live` and returned while the descendant was still alive,
so teardown's "no subprocess outlives the fiber" (and its JSDoc) was false for
that window. The run now stays in `live` until the process-group poll confirms
the group empty, at which point it is both dropped from `live` and its finished
promise resolved. Adds a regression test asserting dispose() of a completed run
with a same-group survivor returns only after the survivor stops executing.
The class docstring still credited the GIL plus per-frame PIPE_BUF atomicity for
serializing writes, which _write_lock's full-write loop already superseded. State
the current contract (writers serialized by _write_lock around a full-write loop)
and drop the double blank line under the binding-replies note heading.
Record that die_if_cpu_exhausted compares against the effective clamped cpu_soft
in the rlimit section, and add the recheck-timeout test to Testing; re-record pair.
The settlement-time CPU recheck compared spent CPU against the configured
cpuSeconds, but _clamped may have lowered the effective soft limit to a stricter
inherited value. A program that traps SIGXCPU, burns past the inherited soft,
and returns inside the soft-to-hard gap was checked against the configured value
and falsely reported successful, bypassing the inherited limit. The recheck now
uses the clamped cpu_soft. Adds a regression test that inherits a 1s soft CPU
limit and asserts a SIGXCPU-trapping over-burn is a timeout, not a success.
Record the call_soon_threadsafe-onto-a-closed-loop guard in the binding-reply
section of the settlement-fixes Agent Note; re-record the bilingual pair.
A binding called from a worker thread records that thread's loop for its reply.
If the thread finished and closed its loop before the host reply arrived,
_pump_replies' call_soon_threadsafe onto the closed loop raises RuntimeError;
unguarded, that ends the pump task and strands every later reply. Wrap the
schedule in a try/except that drops the moot reply (nothing awaits it) and keeps
the pump serving.
A descendant that calls setsid()/start_new_session leaves the child's process
group, so kill(-pid) teardown cannot reach it; if it also releases the inherited
pipes the run still settles and the fiber goes quiescent while the orphan runs.
This is the containment boundary (model code has bash-equivalent trust), not a
guarantee; reaching such an orphan needs descendant-pid tracking and is deferred.
Two further review findings on the CPython backend:
- The grace-window SIGKILL timer was left armed after settlement, so on a
normal completion a kill(-pid) could fire up to graceMs later and strike a
recycled pgid once the kernel reused the leader's pid. settle() now clears
the timer the moment the process group is confirmed empty (the normal path
and when the poll sees the survivor gone), bounding the reuse window to the
genuine-survivor case where the group cannot be empty to reuse.
- _clamped bounded rlimits by the inherited hard limit only, silently raising
an inherited soft limit stricter than the request (loosening RLIMIT_AS or
deferring RLIMIT_CPU SIGXCPU). It now clamps each side against its own
inherited counterpart and pins soft under hard, keeping the strictest of
configured and inherited. Adds an inherited-soft-limit regression test.
Agent Note expanded to seven fixes with the two new rejected alternatives;
zh pair re-recorded.
Two review findings on the CPython backend:
- Disposal could return while a same-group descendant that ignores SIGTERM
but releases the inherited pipes was still alive: the leader's close fired
and the previous fix relied on an unref'd SIGKILL timer that a short-lived
host never fires, reparenting the survivor to init. settle() now withholds
the run's finished promise on a ref'd process-group poll until the SIGKILL
has emptied the group (bounded by graceMs + margin, zero-cost when already
empty), so teardown's "await each child's exit" holds.
- A binding called from a model worker thread via asyncio.run created its
reply Future on that thread's loop, but _pump_replies completed it directly
from the main loop; asyncio.Future is not thread-safe across loops, so the
call hung to the wall clock. Replies now complete via the owning loop's
call_soon_threadsafe, and a lock serializes the id claim/write/advance.
Tests: the same-group reap case now asserts a heartbeat file stops (robust
whether the killed descendant is reaped or a zombie, so it holds where PID 1
does not wait() orphans); a cross-loop case runs a binding from a worker
thread and asserts the reply round-trips instead of timing out. Agent Note
expanded to all six fixes with rejected alternatives; zh pair re-recorded.
The frame-ceiling cap test asserted the old (ceiling-envelope)/6 bound and
its 44739232 message. The load bound is now ceiling-envelope because both
budgets are metered in already-escaped bytes; assert 268435392.
Address review findings on the CPython backend:
- CRITICAL: a model program could leave a descendant in the child's own
process group that ignores SIGTERM but releases the inherited pipes, so
the leader's `close` fired and settle() cancelled the pending SIGKILL
before it escalated — run()/dispose() returned while that child lived.
kill() now unrefs the grace timer and settle() no longer clears it, so
the SIGKILL reaches the whole group; killGroup swallows ESRCH when the
group is already gone (the normal case). Adds a real-subprocess
regression test.
- WARNING: the maxLogBytes/maxValueBytes load bound divided the frame
ceiling by 6 for escape expansion, but both budgets are metered in
already-escaped serialized bytes, so a payload occupies at most
cap+envelope on the wire. Bound is now ceiling-envelope; drop the unused
escape constant.
- Narrow the runtime.spec.ts header to "no subprocess mocks" (it mocks
node:fs.copyFileSync for staging-failure cases).
- Use full-width punctuation in the README.zh.md prose per translation
rules; re-record the pair.
The package README (both languages) still described this layer as
protocol-only with the PythonCodeRuntime implementation deferred to a
later PR, contradicting the shipped code. Rewrite the intro to describe
the registered runtime, add a Configuration section for every Config cap,
and drop the "implementation not in this layer" limitation. Also pin the
residual-detach fixture's size invariant: the byteLength assertion only
holds above Node's Buffer pool threshold.
The manifest omitted @deepseek-ai/dsh-code-runtime although src/index.ts
imports CodeRuntime and the portable-identifier constants from it and the
tsconfig references ../code-runtime. A three-way package.json merge over
the protocol-layer stub dropped the entry; restore it in peer and dev
dependencies so the declaration matches the import.
Unwrap the English note to one physical line per paragraph (verify-md-wrap)
and retarget the backend link to the fd-3 protocol architecture note that
this stack actually ships (verify-md-links); re-record the bilingual pair.
Land the PythonCodeRuntime implementation on top of the fd-3 protocol
seam: python3 -I per run, binding namespace over fd 3, RLIMIT_CPU/AS,
wall-clock timer, and SIGTERM->grace->SIGKILL process-group teardown,
with the real-subprocess integration suite.
Fixes three defects surfaced on the source PR's review before they ship:
- boot-write failure resolved a worker-exit through finish()/settle()
that read wallTimer/onAbort/live in their TDZ, rejecting run() instead;
the boot write now runs after those bindings and the v8-ignore that hid
the branch is removed.
- log capture serialized against settlement with no lock while model
daemon threads keep writing; LogBuffer now owns one shared re-entrant
lock taken by write/flush_line/push.
- the fd-3 line residual was a subarray view pinning the whole joined
frame; it is copied into a right-sized Buffer via detachResidual so
pendingBytes measures what is retained.
Resolve the 08-08 note conflict (keep the zero-build rewrite, drop the
SQLite busy-journal sentence removed with the SQLite backend) and drop the
now-removed session-persistence-sqlite built-package suite from the
lib-consuming self-skip inventory in the ci.yml comment, the
ci-workflow.spec.ts comment, and the partitioned-coverage note; the
inventory is now image-loadable, transform-corpus, and client-bundle.
cache.spec.ts polled fire-and-forget fail-soft writes with a fixed 40ms
settle(); contended runners drain the write after the window, so the
warn/row assertions flaked. Poll the observable outcome with vi.waitFor
(5s) instead, matching the file's existing cold-read write-back pattern.
The sdk-client and subagent-dsh-sdk dispose-ladder tests passed tight
confirmation budgets (disposeGraceMs 100-300ms) to real children; on a
contended runner the SIGKILL exit edge can arrive after the budget and
close() misreports a slow reap as failure. Use the product-default
budgets (disposeGraceMs 3000ms) for the real-child cases; the fake-child
negative cases in dispose.spec.ts keep the 10ms bound.
client-bundle.client.spec.ts reads packages/client/ui-trajectory/lib/client.js
and skips all three cases when the bundle is absent, so it is a fourth
lib-consuming suite in the instrumented corpus. List it beside built-package
in the ci.yml comment, the ci-workflow.spec.ts comment, and the
partitioned-coverage note (both languages).
Both coverage lanes now run before any build, so the post-build
uninstrumented gate wording applies only to the serial-windows complete
reference; preview builds still exercise the suite against real
artifacts.
Strengthen the ci-workflow.spec.ts guard to match any 'pnpm run build'
spelling (corepack prefix, multi-line run blocks) instead of one exact
string, and complete the lib-consuming self-skip inventory with the
webworker-runtime transform-corpus import sweep alongside the packer
image assertions and the built-package check. Update the ci.yml comment
and the partitioned-coverage note (both languages) to match, and drop the
stale 'post-build' phase wording and the native-Windows build-wait
rationale from the coverage-exempt comment.
The windows-coverage job built the workspace before running the same
ci-coverage gates as Linux, but the instrumented corpus resolves
workspace imports to src through the tsconfig paths map and never
consumes lib/; the two lib-consuming suites (webworker-packer
image-loadable, session-persistence-sqlite built-package) self-skip on
unbuilt checkouts, exactly how the Linux lane already runs them. Remove
the build step so both lanes behave identically, and pin the zero-build
invariant in ci-workflow.spec.ts (red before this change, green after).
Agent Notes updated in place: corrected the build-wait rationale and the
wrong attribution of the packer assertions to the instrumented suite.
pnpm hardlinks node_modules files to the store on the same volume, and
TypeScript's native realpath resolves those links back to store paths
(F:/.pnpm-store/v11/files/...), producing TS6231 during tsc -b and vite
resolution. ReFS block cloning (package-import-method=clone) gives each
file an independent path while sharing physical blocks, avoiding the
leak without the copy cost. Clone mode needs the @reflink/reflink native
module, which the system corepack pnpm carries but pnpm/action-setup's
dest build omits, so installs run through corepack pnpm.
The install steps branch on the workspace filesystem: clone only on
ReFS, plain install on hosted NTFS (which rejects copy-on-write). The
serial-windows store points at F:\.pnpm-store to share the ReFS volume.
Agent Note 2026-08-30-windows-refs-store-block-clone-install records the
rationale; ci-workflow.spec asserts the branch.
The loader's entry store is a plain object, so an auto-generated all-digit
id is reordered ahead of its siblings by integer-key semantics and the
previous ordered assertion flipped on roughly one in fifteen runs. Row
ordering belongs to loader.entries(), not to this projection; the spec now
asserts each row by its id.
CI's coverage lane runs on a clean tree where workspace imports resolve
through tsconfig paths to src; the value import of
@deepseek-ai/dsh-agent-presets/display therefore needs its own paths row
beside ./types. Locally the built lib masked the gap; reproduced by moving
lib aside, fixed, and re-run green under the same condition.
Review round on #3316: the composition inventory answers from a standing
mount before the broken verdict (a file corrupted after mounting no longer
hides the running composition), livePresetMounts filters by the caller's
root fiber so a second Cordis runtime in one process never answers for it,
compositions carry trust and the plugin list resolves shipped preset names
through the shared dsh-agent-presets/display fold over ui-agent-preset's
dictionaries (INLINE_SAFE inline import; no cross-plugin runtime import),
the condition detail label reads Disabled when/禁用条件, and the stale
four-surfaces comment says three.
A settled top-level `read_image` call printed its raw attachment object as
literal text in the tool card — `{"type":"image","attachment":{…}}` —
instead of the image, because no presentation metadata told a client card
how to present the reference and the tool-card layer had no image concept.
Host: `read_image` declares an `output.presentationMeta` persisting
`{ path }` only. The attachment reference deliberately lives in the
settled result content — the single record a `tools/post-execute`
replacement rewrites — not in `meta`; the id is opaque and
provider-owned, checked for existence only.
Client: `imageCardModel` derives the card from the call head, the meta
path, the result's own image block, and a shape-matched envelope. ToolRow
gains an `image` card slot; the `read_image` toolview declares the
Tool-owned `tool.call.images` slot as its child and dispatches the
gallery through it. ui-chat down-threads the session-authorized loader
(`ChatNodeOwnerProps.loadImage`), so the tool layer supplies only derived
references plus the loader and never imports an attachment
implementation; ui-attachment fills the slot with its message gallery
renderer. The card keeps the envelope text below the gallery for the
no-attachment-plugin deployment. An image-bearing tool registers a keyed
toolview; the generic fallback keeps its flattened text. `read_image`
joins the read variant with its own locale title key; both rows share
`read-family-row.tsx`.
Verification: `read-image.spec.ts` (metadata projection, envelope by
shape, reference narrowing, real-execution round trip, rejection
branches incl. non-digest ids), `image-card.client.spec.tsx` (derivation,
row render site dispatching the slot, keyed registration with the
child-slot declaration, empty-slot fallbacks, media-type enum), keyless
snapshots (`read-image-gif` added; read-image/-dimension/-reencode
updated to the `{path}` meta), five injected-defect negative controls,
and a demo GIF recorded from this PR's head through the official
image-capable model.
Reconciled with the scope-grouped plugin list: compositionInventory keeps
its additive block over master's RemoteError refactor; the slimmed
settings-store keeps ctx-based signatures while staying a display-only
roster store (no describeFace, no select); dead transport-rejection tests
dropped with the wire that no longer rejects; module graph, catalogs, and
harnesses regenerated against the merged tree.
Both scope groups drop their boxed chrome for the General-settings row
idiom: a title row (session-plugins title with the right-aligned preset
selector pill; global-plugins title), a grey subtitle line carrying the
count, a hairline divider between groups, and the cards grid below.
Counts ride the subtitle as text while the data attributes keep the raw
numbers for tests.
Review-driven refinements to the scope-grouped plugin list:
- The preset switcher becomes the General-settings selector pill over the
shared Menu primitive instead of a native select, and the preset group
is collapsible like the global one (search still forces both open).
- The session-plugins drawer is removed: rows the presets took over sit
inline in the global list with the preset-provided tag and per-preset
details, since the preset group above already shows those compositions.
- The status dot renders only for a live root fiber, so file-state rows
of an unmounted preset carry their enablement tag alone instead of a
column of grey dots.
- PresetTree reclaims the owning entry's subtree slot: EntryTree's
constructor filed the standing mount under the roster's own Loader row,
so after the first session composed a preset the whole composition
leaked into root loader.entries() as host rows (each preset overwriting
the last). A regression test holds the root entry list identical across
a mount.
The settings plugin list projected ctx.loader.entries() alone, hiding the
plugins sessions actually run and rendering the web overlay's deliberate
disabled tombstones (tool-bash, tool-fs, ...) as two dozen plainly disabled
rows while the same modules ran in every standard-preset session.
- dsh-agent-presets: compositionInventory() answers flattened rows per
preset — newest live standing generation when mounted, composition file
otherwise with !!js disabled gates evaluated against the Loader context;
reading never mounts (regression-tested), refusal stays 'conditional',
raced files report broken with the reason.
- dsh-host-plugin-inventory: list() gains an optional agentPresets block,
resolving the roster as an optional peer and mapping fiber states to the
public phase vocabulary.
- ui-settings-plugin-inventory: preset group first behind a display-only
switcher opening on the default preset; global group collapsed with
failures floated; host-disabled modules enabled by >=1 preset fold into a
session-plugins drawer naming providers; search spans scopes and points
at matches in unselected presets.
- ui-agent-preset: the General-settings default-preset row is deleted — the
roster section's make-default and the new-session chip keep the field —
and the settings store slims to the display roster the header label reads.
Docs, catalogs, module graph, settings-chrome goldens, and the bilingual
Agent Note ride along.
A pointer drill in the @ menu left no breadcrumb and a crumb click dropped
the header, while the keyboard drill worked. InputTriggerController.settle
assigned `drilled` after execute() returned, but a pointer mousedown runs
outside any Lexical update, so the descent edit commits discretely and
re-enters track() during execute() — where refreshHeaders and
fetchCandidates both read the claim while it was still clear.
settle now claims the drill before dispatching the edit and withdraws it
only when the edit is refused, which mutates nothing and so drives no
re-entrant track().
The skill carries the reliability rules, but nothing an agent loads by default
said that specs run concurrently at all. The testing policy described tiers and
evidence without ever stating how a spec is executed, and neither subtree
AGENTS.md mentioned it — including scripts/, where the two suites that recently
failed on unrelated branches live.
docs/testing.md gains the execution model as the one home for the fact: forked
workers, concurrent coverage partitions beside other gates, and self-hosted
runners sharing a host and volume, with the rule that a spec passing only when
run alone is a defect in the spec. It links the skill for the detailed rules.
packages/AGENTS.md and scripts/AGENTS.md carry the short actionable form and
link that section, so the rule is present in the context loaded while a test in
either subtree is being written.
Both ceilings are raised for the added words and the targets in docs/AGENTS.md
move with them: docs/testing.md 1150 to 1300 (now 1237) and packages/AGENTS.md
675 to 750 (now 712), each keeping the 5% headroom the standard requires.
The 'Test strength' bullet carried assertion strength, external-state
verification, the reliability reference, and the coverage caveat at once.
Splitting the reference into an adjacent entry matches how the orientation
list above names the same skill, and restores 'Test strength' to one subject.
The new entry also names the platform and timeout-budget rules the skill now
carries, so the checklist covers what a reviewer is being pointed at.
Two failure classes the repository paid for are not covered by the isolation,
synchronization, and teardown rules already in the skill.
A value the operating system owns is not guaranteed to return as written. A
test may write one back only where the assertion tolerates that write-back
failing; where the assertion depends on it, the expected value comes from a
fresh read. NTFS truncating a fractional-millisecond mtime and Windows folding
environment variable name case are the two instances seen so far.
A describe or case timeout overrides the runner's --testTimeout rather than
yielding to it, so a value below the lane budget lowers what CI granted, while
the same literal reads as a widening where the host default is smaller. The
hook budget travels with the test budget, and a case asserting a timeout keeps
its outer wait far larger than the timeout under test. Restoring a granted
budget, or sizing a bounded retry to measured contention, is named as distinct
from the masking fixes the skill rejects.
The diagnosis reference gains the platform differences under its platform
class, a classification path for self-hosted pools that expose no host metrics,
and the stopping rule for a signature no available host can reproduce.
The Windows coverage lane grants DSH_COVERAGE_TEST_TIMEOUT_MS=90000, but two
paths declined it.
scripts/install-lefthook.spec.ts took a describe-level 30_000, restated as a
per-case constant on five cases. Every case drives spawned Git and Node
subprocesses; the slowest costs 7.5 s on an idle host, so the ceiling carried
roughly fourfold headroom and fired on branches that did not touch the file.
The suite takes 90_000 and the redundant constant is removed.
coverageTestTimeoutArgs raised --testTimeout and --expect.poll.timeout but left
--hookTimeout at Vitest's separate 10 s default, which removeFixtureSafely's
documented 10-second Windows retry window meets exactly. Raising only the test
budget would move a contended suite's failure into its teardown.
- api-gateway reference (en/zh): gateway/lookup-unavailable and
gateway/internal replace the pre-convergence codes, and the resolver
paragraph states the RemoteError pass-through semantics.
- failure-vocabulary note (en/zh): the package is dsh-util-time, the
marker is isDSHRemoteError, and discrimination requires no
instanceof at all.
- protocol: isDSHRemoteGatewayError -> isDSHRemoteError (the class is
protocol-wide, not Gateway-specific); remoteErrorOf drops its
instanceof Error precondition and tests the marker plus a string code
structurally, so a marked failure from another realm no longer reads
as a local defect.
- session-controller: the live-follow packed-record protocol violation
now throws a marked RemoteError('gateway/internal'), landing the
session in openState=error instead of an unhandled rejection;
pinned at the transport and session levels.
- util-time: correct the invariant companion's @module name.
- regenerate the tool-cordis catalog for the marker rename.
- api/gateway: $host caches its RemoteHostFacts record and mints a new
one only when home changes, so snapshot readers compare by reference;
identity pinned in the client spec.
- client/ui-tool, client/ui-workspace: the hooks channel exposes the
host facts record as hostInfo and components select the field they
need (useHostInfo(info => info.home)); row-component contracts are
unchanged.
- gen-cordis-catalog / gen-cordis-inspect-catalog / gen-client-catalog /
gen-config-catalog / gen-doc-graphs / gen-module-graph outputs pick up
the converged Remote vocabulary (gateway/* codes, RemoteError JSDoc)
and the dsh-util-time package; the zh sides of the three
English-generated pages follow the same line-number shifts.
- the message-feedback protocol golden records the accepted wire
change: a boundary-validation failure now reports
gateway/input-invalid with structured details instead of a bare
internal code.
- new cookbook page adding-a-remote-api (en/zh): the five-step HOW-TO
for declaring, failing, registering, consuming, and testing a Remote
endpoint.
- new Agent Note ctx-remote-failure-vocabulary records this round's
decisions and alternatives; the 2026-08-02 and 2026-08-10 notes are
rewritten to the shipped facts (RemoteError vocabulary, $host, the
retired ApiProxy statements).
- package READMEs pick up the new failure-face contracts
(typert/protocol, api/gateway, api/remotes,
test-support/client-runtime), dsh-util-time gains its README and
registry entries, and stale connection/WorkspaceError/legacy-code
statements are corrected (ui-settings, ui-settings-models,
workspace-controller, docs/subsystems/typert incl. the
TypertGatewayErrorCode type-equiv block).
- packages/AGENTS.md gains the Remote-failure rule bullet; its doc
budget rises 675 -> 714: the bullet is the compressed remainder
after relocating detail to the cookbook and the Agent Note.
- api/gateway: mark terminal Remote-stream escapes (carrier retry
exhaustion and pre-acceptance end classification) as
RemoteError('gateway/internal') at the two escape points; marked
failures pass through verbatim. The carrier class stays the
retry-internal signal for carrierFailed and the ended(true) retry
trigger. Regression coverage lands on the session and workspace
stream consumers.
- client/ui-tool, client/ui-workspace: read $host.home through a hooks
observable subscribed to connection/reset; the slot renderer memoizes
inject results per entry, so the previous plain-value injection froze
home at the first render.
- client/ui-settings-models: components no longer receive ctx; apply
binds the credential and settings Remote operations into callbacks,
and the settings/conflict code judgment stays in the apply world.
- classify a carrier throw under a caller-aborted signal as
gateway/cancelled instead of gateway/internal, matching the code the
Host produces when the abort wins the wire round-trip.
- read $host facts from the construction-time Connection handle,
matching $stream; the service cannot be replaced without restarting
this plugin, so the live re-lookup was dead complexity.
- state rebuiltFailure's actual contract in its comment: codes pass
through verbatim without runtime validation.
- correct the @module name in dsh-util-time.
- python/sdk-runtime: add @deepseek-ai/dsh-util-time so the runtime
dependency closure stays closed (dsh-subagent now depends on it).
- api/gateway: drop the dsh.client.external request for
dsh-typert-protocol and admit the protocol package into INLINE_SAFE
instead. The loader module table has no supplier for the protocol
package, so the built client factory threw at require time; the
protocol layer is duplication-safe by design (string marker,
code-based discrimination), which is the inline-safe admission
criterion.
- api/gateway tests: cover the $host getter (live service read,
pre-ready home, and the construction-time fallback after the
Connection service is withdrawn).
Single RemoteError with a merge-extensible, domain-prefixed code map;
owners throw at the failure point; streams surface marked failures;
clients consume ctx.remote directly with isRemoteFailure as the only
discrimination point and construct no failure instances.
Move hover enter/leave from the svg element to the stationary fishHitbox
span so the CSS sway and SMIL morph share the same trigger surface and the
animation cannot flicker when sway displaces the svg from the pointer.
Gate the morph with (hover: hover) to match the CSS and prevent tap-sticky
loops on touch devices.
Remove residual headline changes unrelated to this PR: white-space: pre on
.headlineText, data-testid="hero-headline", and corresponding getByTestId
test assertions — these belong to #2397.
Fix Agent Note coverage claim (was "asserting render states", now accurately
"slot contract") and compress blowhole paragraph to current-state fact.
Retained rows made arbitrate('enter') claim 'pick-highlighted' while
pick() silently declined the pending group, so the key vanished by
coincidence. Check the highlighted group's readiness like Tab does and
return 'consumed' deliberately; record the stale-while-revalidate menu
decision in an Agent Note.
`JsonlSessionPersistence.exists` treats ENOENT as absence and stats the
path's parent first, so a session directory blocked by a regular file
stays a storage fault. Only Windows needs that: it reports ENOENT rather
than ENOTDIR for `regular-file/child`, while POSIX open reports ENOTDIR
before the branch is reached.
The stat ran on every platform and every absent probe. findLog issues
four probes per project directory and the coordinator resolves an id
twice per inspect, so nearly every probe paid it. Counting fs calls
against a five-project store, loading an existing session drops from
40 open + 41 stat to 40 open + 3 stat.
The Turn fold publishes the first step's TTFT (contract/turn-metrics.ts
firstStepTtftMs), never an average; only the Session StatsLine averages
across steps. Rename the dialog row in both locales and align the Agent
Note with what actually ships.
The 2026-08-04 bug-fix note owned the overflow-x clip that existed only
for the glow's bleed; with the glow, the clip, and its test all gone the
note is fully superseded. The new note preserves its rationale and the
reintroduction condition for future bleeding chrome.
conversation-column-overflow existed solely to verify the glow bleed was
clipped; delete it with its golden. The geometry golden picks up the
scroll body losing overflow-x: hidden. reference-composer now waits for
the stale '@' rows to settle before clicking: the menu keeps the
previous query's rows while the next loads, and index-keyed rows swap
content in place.
The turn-stat dialogs copied ContextMeter's document-listener effect, which
the duplication gate flags; useDismissOnOutsidePointer gains an optional
portal ref so the portaled dialog counts as inside, and TurnUsagePanel keeps
only the Escape listener. The icon-count test also learns the two pill
glyphs the branch added.
The blurred blue ellipse (HeroGlow) below the homepage input card reads as
stray tint rather than intentional chrome; drop the component and its
positioning/overflow scaffolding.
Batch of visually verified Web UI fixes: trigger-menu z-index over the
resize handle (#3228, #3229), input scrollbar offset, tool-row file
links and diff stats (#3230), @ menu crumb alignment, light-mode
divider, and @ menu flicker while typing (#3234) via
stale-while-revalidate — a refinement hit keeps the previous items and
highlight on screen until the new generation settles, so neither the
skeleton nor the first-row focus blinks per keystroke.
Every case in the suite drives real git invocations against a scratch
repository, so it is bound by process creation rather than by its assertions.
The describe-level 15 s capped all 23 cases below the 90 s the Windows coverage
lane passes as --testTimeout, and the suite has been observed timing out at
15000ms on a branch that did not touch the file.
Refs #2677.
The A/B test settled on the twin-pill layout, so the TEMPORARY
?usage-variant=flat trigger, its locale keys, and its tests leave with it.
Below 480px the stat pills now take the sibling action-button geometry so
their bare icons keep the row's rhythm instead of drifting on the wider
label padding and the -6px pair rebate.
The turn tail's exposed meta line collapses into two icon pills — Usage
(database glyph, turn total) and Ran-for (clock glyph, wall time) — each
click-opening a details dialog; the calendar clock trails as plain text.
Cache hit, TPS, and TTFT move dialog-only, and narrow viewports collapse
the pills to bare icons. The TEMPORARY flat variant keeps the whole-line
trigger for the A/B test.
Review bot findings: DSH_TOOLS_MODE values, the wire-replacement
wording, 'code-only' mode references, and the spill README's
dispatch-log waterfall name all still named the removed 'code' value.
The review bot found stale 'code' configuration values in the zh tools
and agent-tool-presentation READMEs and the zh tool catalog, which the
runtime schema already rejects in favor of 'ptc'.
Master removed the ApiProxy package; its former test paths now live in
the client connection, API gateway, and settings controller test
directories. Update the three notes' references so verify-package-paths
resolves.
The rebase merged master's SDK-example and telemetry prose with the
ptc renames in the tools and CLI reference READMEs and the executor
collapse note; re-record their pair hashes.
The DSH_SNAPSHOT refresh recorded the internal seq-range form; the
canonical fixture layout expands those ranges. Apply the mechanical
migration instead.
Master replaced the session-log-version-mechanism note with the
fail-closed-session-event-vocabulary note; update the rename note's links
(en/zh) so cross-links resolve.
The subagent review found stale code mode-value prose the mechanical pass
missed: tools and agent-tool-presentation READMEs (en/zh), the CLI reference
page (DSH_TOOLS_MODE and the preset roster), the zh tool catalog, the
execute JSDoc and collapse comments in dsh-tools, the codeModeHarness
helper in agent-loop tests, and stale code-mode titles in ptc.spec.
Apply the rename pass to READMEs and docs the master sweep rewrote, fix
PTC mode anchors and the renamed-note links in the spill READMEs, and
regenerate the doc graphs.
The split kept the session-persistent vocabulary (tool/code-dispatch*,
tools-code-mode, :code:) on this PR, but several prose surfaces still named
the new values: the zh persistence/tool catalogs, the renamed Agent Notes'
event mentions, spill-policy comments, and a garbled 're-enPTC mode'
replacement. Also rename the mode value to ptc in the places the rename
missed (tools and agent-tool-presentation READMEs, the Config JSDoc, note
mode unions) and the codeModeHarness* e2e helpers.
Rename the tool-presentation transport from code-mode to ptc everywhere
that is not written into session logs: the mode config value becomes 'ptc',
the preset directory/id becomes ptc, the demo becomes demo:ptc, the
dispatch waterfall becomes tools/ptc-dispatch-log (types PtcDispatch*), the
prompt rule becomes tools:ptc-only, source/test files become ptc.ts etc.,
and prose says PTC mode / PTC 模式. The session-persistent vocabulary
(durable events tool/code-dispatch*, logged plugin name tools-code-mode,
sub-call id segment :code:) intentionally stays and moves in the stacked
persistence PR, which is blocked until the SESSION_FORMAT_VERSION v0→v1
migration lands with it. run_code, its code parameter, CodeSdkLanguage,
CodeRunFailedError, the dsh-code-runtime family, third-party codex names,
and frozen archived notes keep their names.
The whole-line meta trigger read as plain text and hid what was clickable.
The Turn-usage trigger is now a data-icon pill (Usage {total} · Cache hit
{percent}%) seated right of the branch action with the action buttons'
hover chrome, so the one interactive element in the tail is visibly a
button; the timing facts (clock, run time, speed, TTFT) return to plain
non-clickable text behind a dot separator. The details dialog keeps the
Turn-usage title and full token buckets, gains a permanent cache-hit row,
and breathes with wider vertical padding. Narrow columns trim the pill
label to an ellipsis instead of widening the chat column. User rows and
turn tails share the recency gate: only the latest row of each kind keeps
its actions visible without hover.
chmod 0 can only deny directory reads on POSIX to a non-root owner:
Windows exposes no directory permission bits for readdir, and root
bypasses them. Where the fixture stays readable the sealed candidate is
indexed, so the unreadable-branch behavior is pinned on POSIX non-root.
An injected readdir failure keeps that branch covered on every platform.
Replace Vitest's hash-based --shard with a coordinator-side
longest-processing-time assignment. The coordinator collects the
instrumented inventory from a vitest list run (dropping the exempt
heavy suites that list does not exclude), reads per-file durations from
the Vitest results cache, and seeds heavy subprocess-bound suites into
different partitions. A weight-aware test fails when assignment ignores
recorded weights, verified by injecting a file-count-only rule.
Windows coverage measured partition spread of 442s (275-717s) under
hash sharding; a simulation with the same file durations and the new
assignment balances partitions to within 21s, cutting the critical
partition to roughly half.
collectPackageNames repeated collectPackageAliases' directory walk
verbatim, which jscpd reported as a 7-line clone and which failed the
lint-and-duplication gate on both the Linux and Windows lanes. Both now
read one workspacePackages() iterator: the alias collector keeps only
packages named after their directory, and the coverage collector keeps
every one of them.
Review found the CLI entry guard compared import.meta.url against a
concatenated file:// URL. That fails whenever import.meta.url encodes
something process.argv[1] does not — a repository path containing a
space, or any Windows drive path — and it fails silently: the script
exits 0 having done nothing, so verify-tsconfig-paths would pass
without checking exactly where it is needed. Running a copy from a
directory whose name contains a space reproduces it. The guard now uses
the comparison the repository's seven other generators already use.
Deleting the group wildcards also removed the fallback that resolved a
package nobody had aliased, so the generator now asserts coverage:
every workspace package with a src directory must be mapped, and
--check names any that is not. That assertion immediately found four
packages named dsh-<group>-<directory> whose siblings carry hand-written
aliases while they did not, so they reached built lib/ output through
the workspace symlink. They now carry aliases too, which takes the
resolution differences in this branch from seven to eleven.
Two comments in tsconfig.base.json still pointed at the deleted
wildcards; they now state why those aliases stay hand-written. The
package-inventory proposal recorded the wildcard collapse as current,
so both notes are cross-linked as partial supersession.
The rebase onto master's turn-process folding kept master's makeHarness
rework, which dropped the turnUsages passthrough and the single-trigger
footer assertions; re-merge both sides.
Replace the two-row footer (TurnUsageDisclosure + icon-row clock chrome)
with a single whole-line trigger (clock · run time · turn usage · cache
hit · speed · TTFT) that opens a per-Turn usage dialog. The latest turn
keeps its tail always visible; older turns reveal the whole row on
hover/focus. Turns without usage data keep the plain clock line with
identical spacing.

tsconfig.base.json resolved @deepseek-ai/dsh-* through 49 candidate
globs and @deepseek-ai/dsh-*/invariant through 45, one per package
group. Resolution tries candidates in order, so a package late in the
list paid for every earlier miss — and under the dsh source launch each
miss is an ERR_MODULE_NOT_FOUND that Node decorates with a full
CommonJS resolution walk. A boot profile attributed 934.6 ms, 35% of
startup, to that decoration path across 60,942 failed resolutions. The
cost landed hardest on packages/util/*, which sits at position 44 of 49
and holds the leaf utilities nearly every plugin imports.
gen-tsconfig-paths writes one explicit alias per package into a marked
region and both group wildcards are gone; verify-tsconfig-paths reports
drift and runs in the ci-static lane. Booting the headless profile from
source drops from ~2,157 ms to ~1,055 ms with --help output unchanged.
All 1,022 dsh specifiers in repository sources resolve to the same
target as before, except seven /invariant specifiers in the lsp,
terminal, and runtime-diagnostics groups that the deleted wildcard
never listed: those reached built lib/types instead of src, against the
rule that static gates resolve through paths to src on a clean tree.
Progressive enhancement on body in the shell base sheet so mixed
Chinese/English copy gets consistent spacing without content edits;
engines without support ignore the property.
A steer or follow-up accepted while a turn is closing is now claimed by a
fresh turn at the driver's clean exit instead of stranding in the inbox;
cancellation and pre-step rejection still park accepted work. Continuable
subagent follow-ups accept image parts: the wire is upload-shaped, the Host
admits and persists each batch before inbox acceptance, and delivery is
refused when the child model declines image input. The queue dock renders
durable image thumbnails instead of an [image] text marker.
Fixes#3186
A title now comes from an attached session's live projection cut or a cold
one's durable checkpoint, and from nothing else. Attachment is decided by the
session store at read time, so a session that attached after the listing is no
longer answered from a checkpoint its log has moved past — the stale-title case
`api-session.list` already handles this way.
The log fold and its per-log memo are gone. Folding one title costs a whole
log, and this call sits under every keystroke; a session no projection answers
for is labeled by its id and regains its title the first time it is opened.
`lib` leaves the default exclusions: Ruby gems and many npm packages keep
sources there, and the miss would be silent and total. A traversal whose root
is unreadable now rejects instead of publishing an empty index over entries
that are still good, which is what the stale-while-revalidate path claimed but
could not do while every readdir error was swallowed. A drill marks the menu
drilled only when its edit actually reached the draft.

Refs #3180
Review found the shared observation defeated the very fence it fed:
it carries the original PID-to-start-time pairing forward, so a
recycled PID still matches it and takes a signal meant for the process
that exited. Capturing it outside the per-member try also let one
failed read abort a whole teardown round, breaking the synchronous
host-exit contract, and an empty round paid a read for no members.
signalProcess now reads ProcessInspector.isAlive immediately before
delivering, from the narrowest per-identity source each platform
offers; signalMembers and waitForMembers return before capturing when
a round has no members. snapshot() keeps serving the readiness poll,
whose per-poll table read stays at one.
Windows enumerates Toolhelp32 lazily on the first tree question, so a
snapshot asked only for liveness — the 25 ms teardown poll — performs
no table walk at all.
Replace the debounce-timer polling with Include.stop(), which flushes the
file-backed write queue deterministically. This avoids Windows coverage
flakes where the self-dispose write could land after the expect.poll
timeout.
TurnNavigator was an unmemoized component rendering one div and one
button per loaded Turn, so every ChatView render rebuilt the whole rail:
143 button rebuilds per commit in a 300-Turn session against 8.4 in a
4-Turn one, while a streaming answer commits dozens of times.
memo alone would not have helped, because navigateToTurn was rebuilt on
every render and broke prop identity, so it moves into useCallback.
MacProcessInspector answered the descendant tree and every member's
liveness with its own `/bin/ps` fork, so one readiness poll cost N+1
full table reads for N tracked descendants. With execFileSync on that
path and a 50 ms poll interval, any command spawning two or more
children saturated the host event loop until it exited.
ProcessInspector.snapshot() now returns one ProcessSnapshot that
answers tree, session, and alive from a single observation, and
signalProcess takes the caller's observation so its PID-reuse fence
does not re-read the table per member.
Collapsing every relative-time bucket to `{{age}}` reached the session-tree
goldens, where a literal age is the assertion: a fresh row reads `now` and an
older one does not. Six e2e files failed, two of them by aborting mid-scenario
and leaving their replay fixtures half-consumed.
`captureStableAria` now takes the rule as an opt-in, and only the reference
menu — whose rows are dated from the live Host list — asks for it.
Refs #3154
The Host session list already carries each session's `updatedAt`, which is
the number its own rows show; reading it there keeps the two surfaces from
disagreeing and avoids making a context capability depend on the BFF
assembly that owns the `sessionListMetadata` projection. A session the list
does not carry falls back to the candidate's creation time.
Refs #3154
Session candidates labelled from projection checkpoints instead of a full
log fold per keystroke, with the uncheckpointed remainder folded once and
memoized while its log stays cold. The file index keeps answering while an
invalidated traversal rebuilds behind the caret, and its default exclusions
now cover build outputs so deep sources stay reachable.
Rows carry only what distinguishes them: a file names its parent directory,
a session names its workspace only when that workspace is not the current
one, and a drilled listing names none because its new breadcrumb does.
Resolves#3180
Related to #3154
Stacked on #3115: keep its windows-* setup-pnpm-js-<run_id>-<run_attempt>-<job>
destination, and extend the same isolation to non-Windows jobs in ci.yml
and ci-master.yml with setup-pnpm-<run_id>-<run_attempt>. This prevents
sequential self-hosted Windows jobs from tripping over a stale locked
pnpm.exe/reflink native module.
The anchors-a-relative-add-spec case serializes two subprocesses (plugin
add + remove) under a hardcoded 90s budget, which the 2x60s worst case
exhausts; derive it from SPAWN_TIMEOUT_MS * 2 + 30s like the other
dual-call cases. The pnpm setup isolation note now also records the python
SDK exe build's suffixed destination and its regression-test coverage.
The merge resolution had reverted THIRD_PARTY_NOTICES.md to the SDK 0.3.220
rows; the lockfile pins 0.3.241, so CI regenerated a mismatch. The apply spec
now drives the injected onHover face, closing the per-file coverage gap on
src/client/index.ts.
The plugin add and dump-default-config cases serialize two runBuiltBin
calls, each with a 60s execa cap; the 90s outer budget could be exhausted
before the second call. Raise them to SPAWN_TIMEOUT_MS * 2 + 30s, matching
the multi-call treatment.
Candidate rows lead with domain icons instead of localized text
prefixes; pointer and keyboard share one reducer-owned highlight (last
input wins); drillable folder rows reveal a localized Browse-folder +
Tab keycap hint with the library chevron; pending sources render
skeleton bars; the menu spans the composer card. The editable @dir/
text decorates color-only — the domain icon now belongs exclusively to
the settled reference chip. Composer placeholders advertise / and @,
and the zh copy for commands is unified to 指令.
The Agent Note (both languages), the PR prose, and the commit message
claimed a 13px floor for the table variants; the formula has none —
max(13px, setting − 2px) selects the −1 branch at low settings rather
than clamping the result, so the tier bottoms out at 11px at the 12px
setting, matching think text. Rewrite the claim, say so in the axis
comment, and split the README sentence that lumped body-pair and
secondary-pair consumers together.
Assert the engine-resolved secondary size in the settings-chrome e2e
(13px at the default, 13px at the 15px boundary, 14px at 16px,
unchanged across reload), sync the StatsLine and workflow-panel spec
headers with the tier they now pin, and note why memberLabel stays at
the body size.
Derive --dsh-content-font-size-secondary (setting -1 at <=14, setting -2
above; 13px at the default) with --dsh-content-font-delta-secondary in
gradient-shadow-text.css, and move every one-step-under-the-body text
onto it: think text and reasoning summaries, the shared DisclosureRow
title, ToolRow and bash-row summaries and file links, compaction/
context/command/retry/error rows, StatsLine, the workflow-run panel
tiers, reference summaries, the turn-status clock, and the feedback
note trigger. The markdown table variants join the same tier instead of
staying fixed; its 13px floor keeps them legible at the 12px setting.
At the default setting the flow-row titles and summaries render at 13px
(previously 14px) so they match think text at every setting instead of
sitting 2px above it.
The requires-profile and routes-help cases serialize 4-6 runBuiltBin calls,
each with a 60s execa cap; under the loaded pool the 90s outer budget was
exhausted before the last call and vitest truncated the run without the
execa diagnostics. Raise both to SPAWN_TIMEOUT_MS * 3 + 30s.
* ci(build-exe): drop pull_request label trigger to avoid skipped checks
* docs(build-exe): sync agent note and pin event set in workflow spec
* test(ci): type-safe event key assertion for build-exe workflow
* ci(build-exe): use present-tense trigger comment and drop label-run note
The built-bin help/usage case still used a win32-conditional 60/30s outer
budget while serializing six runBuiltBin calls, and startProfileLifecycle
lacked the execa timeout/killSignal the sibling helper has; the tool-ralph
cases pinned 20-30s explicit timeouts that the 90s lane default cannot
override. Align all of them to the SPAWN_TIMEOUT_MS + 30s (or 90s) pattern.
The per-case 15-30s budgets on the Windows native and coverage lanes fire
before oxlint, workflow-worker-thread, and other subprocess-spawning cases
finish under the loaded self-hosted pool; the failures rotate across cases
as load shifts, so per-case widening only moved the flake. Raise the lane
defaults (DSH_COVERAGE_TEST_TIMEOUT_MS and the native --testTimeout) to 90s,
align the oxlint and workflow-worker-thread case budgets, and keep the
built-bin SPAWN_TIMEOUT_MS at 60s under a 90s outer budget.
The provider-card seat's keyConfigured now derives from the reference the
page would use — the profile's apiKeyEnv, or the page's derived
<ROUTE>_API_KEY while the profile names none — so the add-provider draft
agrees with its own editor about an existing conventional credential (the
store joins the derived describe in the same batched call, as
ProviderRow.derivedCredential). ModelsSectionProps makes the renderSlot seat
required so a direct render that forgets it fails to compile; the one such
render in provider-form.client.spec regained a real mount and the test
boilerplate collapsed to renderSlot={() => null}. The extension-slots Agent
Note now states the keyed cell's real override rule (same priority throws,
a different priority shadows), and docs/subsystems/slots.md carries the two
new seats in its hierarchy, both languages.
The windows-* jobs now install pnpm under a run/attempt/job-suffixed
destination, so the pre-install step that cleared the old fixed
setup-pnpm-js path no longer touches the actual destination and its
comment claims stale state. The suffix already gives every job a fresh
directory, so remove the four cleanup steps.
The execa timeout was widened to 60s but the outer vitest case budgets stayed
at 30s, so a cold-starting built bin would trip the vitest budget first and
the execa SIGKILL cleanup could not run inside it. Extract SPAWN_TIMEOUT_MS,
share it across the execa deadline, its error text, waitForFile, and the
outer case budgets (60s spawn + 30s headroom), so the widening is coherent.
Both suites spawn real subprocesses (oxlint probes; the dsh built bin) that
cold-start slowly on the contended self-hosted Windows pool, so their 20-25s
timeouts fire before the child finishes. Raise the oxlint contract case
timeouts to 60s and the built-bin execa timeouts to 60s, matching the
tool-ralph budget treatment.
The windows-* jobs keep a separate standalone pnpm executable under
runner.temp/setup-pnpm-js. A previous job on the same self-hosted runner
can leave a locked @reflink native module there, so the next job's
pnpm/action-setup fails with EPERM during unlink before any test runs.
Suffix the destination with run_id, run_attempt, and job so every job
gets a fresh directory even when sequential jobs land on the same
runner; apply the same to the python SDK exe build. Update the pnpm
setup isolation note to record the Windows-specific destination.
pi-ai credentials carry optional members as explicit undefined (a github.com
Copilot grant holds enterpriseUrl: undefined), and the store bridge committed
the object verbatim, so the credential store's strict validator refused the
write and sign-in failed after the provider had already authorized it.
toRecord now drops explicitly-undefined members and renders undefined array
entries null, exactly as JSON.stringify would; everything else passes through
untouched so genuinely unstorable values still fail loud at the store.
Review follow-ups: wait on the caller's own locator instead of assuming
it is the page's first composer, describe the actual read-only window
(submit adjudication and locked states — a running turn stays editable
for queueing), drop the pre-Lexical narration from the JSDoc, and record
the gesture-semantics trap as an Agent Note.
The Models section now declares two SlotMap seats for out-of-tree plugins:
settings.models.provider-card (keyed by the row's settingsNs, dispatched on
saved cards, the first-run setup posture, and the add-provider draft, with
the row view, configured join, and confirmed api-key state as owner props)
and settings.models.footer (ordered list after the rows and add controls).
Without registrants both seats render nothing. First consumer: the
llm-pi-ai-oauth companion plugin's sign-in surface.
`import.meta.resolve`'s `parentURL` argument takes effect only under
`--experimental-import-meta-resolve`, which no launch passes, so the
fallback resolved from this module rather than from the harness — the one
question it existed to answer. The disk walk is the whole answer now, and
the refusal memo it needed goes with it. A `file:` URL joins the file
branch rather than the package one, where a resolver would only normalize
it and report a missing target as present, and a row is skipped on the
Loader's own `Boolean(disabled)` so `disabled: 0` is checked like the
Loader checks it.
A broken card says so through `aria-disabled` rather than `disabled`, and
refuses the pick in its own handler. `disabled` took it out of the tab
order, which with the reason moved onto the badge left it unreachable
without a pointer — reachable before this change, so hiding it was a
regression rather than a path that never existed.
Both notes this decision partly supersedes are updated in place and
cross-linked, one README pair loses an editing residue that repeated a
sentence, and the single-row diagnostic no longer reads "row row 1".
- permission-presets: register the permissions unit synchronously before the
existing-session sweep, so a remount reads folded knob state instead of
treating every session as fresh; add a regression test for that path
- sandbox-policy/terminal-bash: mount the projection registry in the 5 pwsh
terminal tests, the sdk-minimal bundle, and the e2b fixture composition;
declare the new package dependency in both manifests
- plan-mode: restore .strict() on the plan unit state schema and drop the
deleted foldPlanMode from the bilingual READMEs
- session-title/session-projection: sync bilingual READMEs to the mandatory
projection seam and re-record translation pairing
- docs: turnBoundary reader contract, subagent schema comment, token-meter
import comment, sandbox-policy module docstring
A running turn disables the composer by flipping contenteditable to
false on the same element. fill() throws there immediately — a disabled
textarea used to hold it back through actionability — and isEnabled()
reports true for a div regardless, so the permission-policy scenario's
post-settle wait never waited and its next gesture raced the re-enable
render. The window is a few frames wide; #3083's Remote-routed subagent
control stretches settle enough to hit it on CI.
writeComposerDraft now waits for contenteditable="true" before acting,
and the permission-policy scenario drives all four sends through it with
the settle wait pinned to the attribute.
Discovery proved only that a composition parsed, so a preset naming a
package a later rename took away kept a healthy card and its place in
every picker until a person switched to it. It now resolves each row it
can prove will start, reading the package off disk and falling back to
the resolver only for names that look absent — the resolver costs a
synchronous hooks-thread round-trip under the source launch's tsx hook,
which the walk avoids for every row it clears.
The mount diagnostic followed `AggregateError.errors` but never a cause,
so a group that failed on two rows named neither. It now follows a cause
that carries more than its own message.
A refused switch left the chip's label snapping back with no account of
why, which is the only account there can be for a preset that resolves
and then refuses. It announces through the shared Toast, which gained a
caller-set hold for a cause that names packages and rows.
The tenth master merge staged the correct 0.3.241 notices, but the
pre-commit regenerator ran against a local pnpm store that still held a
stale 0.3.220 SDK directory alphabetically ahead of it and silently
committed the old payload table. Regenerated after removing the stale
store entries; the lexical rows this branch adds stay.
The generator names the first matching virtual-store directory, so a local
store still holding an older SDK payload alongside the locked one renders
that older version into the notices.
The full-corpus transform gate spawns one child that transforms and imports
every built bundle, so it runs for 8-25 minutes as a single case and
dominates one native Windows coverage partition, blowing its 900s budget
under load. Move it to the coverage-exempt heavy gate, which runs it with
its own worker budget instead of competing with the instrumented
partitions. The package's src is threshold-excluded in vitest.config.ts, so
the exemption carries no coverage; the exempt-heavy roster note records the
entry.
The self-hosted Windows coverage pool (16 shards x 12 workers on 192
threads) pushes real subprocess boots past their vitest deadlines: the
tool-pwsh Loader smoke reaches ~40s against a 30s process cap, and the
tool-ralph worker-thread cases exceed the 5s default. Give the pwsh
smoke a 90s process deadline (the subprocess keeps the assembled boot,
the vitest deadline stays at 120s), and give the two un-budgeted ralph
cases 30s each, matching the existing 20s quiescence case.
On Linux, pwsh may trap SIGTERM and exit cleanly when the subprocess service
is disposed, so the handle status is 'completed' rather than 'killed'. The
test already proved the process tree is gone via kill(pid,0); both statuses
satisfy the contract.
Nothing under packages/host/apiproxy imports @deepseek-ai/dsh-goal after the
unary domain deletion, so the dependency and its project reference go too.
The goal domain has been served by GoalService's @Remote namespace since it
shipped; the API Proxy copy was a second implementation of the same six
mutations. Remove the goals contract, schemas, route rows, IApiClient stub,
host implementation, and the fixture's compatibility face, leaving
ctx.remote.goals as the only path.
The fixture's goal fold keeps its coverage through the Goal Remotes: its
lifecycle case moves out of the unary-dispatch test, which no longer has
goal rows to cover.
Drop the width handle's double-click reset and tooltip — the handle is now
drag-only and a stored preference is only replaced by another drag — and
add a tertiary description line under the Settings font-size title stating
the size only affects conversation content. Update both Agent Notes and
the settings dialog goldens.
Adopt --dsh-content-font-size / --dsh-content-font-delta across the flow
rows around the transcript body: DisclosureRow header (row height, title,
leading box, and registered glyphs, with StateDot exempt), ToolRow and
bash-row summaries and file links, think text, compaction/context/retry/
error rows, message clock and icon actions, the workflow-run panel, and
the workspace browser. Update the font-size Agent Note and add CSS-text
specs for the new adoptions.
The scenario landed on master with a textarea locator; the composer is a
Lexical contenteditable surface here, so the fill waited 30s for a node
that never exists. Use the shared per-key draft helper against
[data-composer-input] like the other composer scenarios.
Other PRs are blocked by Windows ACP half-close tests timing out. Keep the
coverage job running for signal, but remove it from all-checks-passed.needs
until the Windows skip fix is validated.
Windows anonymous pipes do not surface a child stdout EOF while the child
process stays alive. The three tests that simulate 'child closes protocol but
stays alive' therefore cannot be reproduced on Windows and hang until the
test timeout. Skip them on win32.
These tests spawn real ACP child subprocesses. On contended self-hosted
Windows runners the default 30s budget times out. Instead of raising the
global coverage timeout, give this file 2x the configured default
(DSH_COVERAGE_TEST_TIMEOUT_MS) so it follows future default changes.
After the 4-partition split, other PRs' windows coverage now fails on
process-bound subagent-acp tests timing out at 30s under self-hosted
concurrency. Give the coverage lane the same 60s per-test budget that the
earlier failover profile used.
The rail's items now ride the Chat snapshot: a structural upsert re-derives
the loaded Turn set, a content-only upsert re-derives only the Turns whose
nodes changed, and each preview is capped so navigation state never holds a
copy of the transcript. The published array keeps its identity until an item
changes, so ChatView selects it as both data and change signal — and a
streaming reply's preview follows the in-place node update instead of the
last structural publication.
A scroll frame resolves the active mark with one hit test at the reading
line, falling back to a single row scan, rather than a DOM query per mark.
Flow-height changes resync through the existing column observer, navigating
during a pending page keeps the paging anchor, and the rail height no longer
holds a floor taller than the band it centers in.
Render reconstructable system prompts at each request-series boundary, preserve series declarations through pre-step wrappers, and keep the presentation and replay snapshots aligned across clients.
Keep five non-blank rows stable while the selected blank New Session is provisional, and derive the overflow count from the rows still hidden.
Fixes#2841
The rail is a landmark on every Chat wide enough to show it, so each
recorded conversation with at least two loaded Turns now carries the
navigation node and its marks.
The concurrent-migrator test wrote the winner document with a plain
writeFile, whose truncate-then-write window lets the boot's unlocked
initial read observe an empty file and boot an empty store under load.
Seed fixtures through writeFileAtomic instead, matching how the provider
itself persists, so a reader sees either the old or the new complete
document.
ChatView derives one navigation mark per currently loaded Turn, keyed by
Turn number and anchored on that Turn's first loaded user node. The rail
sits against the scrollport's right edge, centered in the band the sticky
composer leaves visible; hover and keyboard focus preview the Turn's
prompt and response, and activating a mark moves the shared scrollport
and records the resulting restoration anchor.
ConversationRoot publishes --dsh-conversation-viewport-height beside the
composer height it already measures on the scrollport, so floating View
chrome can center in that band without assuming a Session header height.
The PR changes native Windows coverage partitions from 8 to 4 to reduce
vitest worker startup pressure under high self-hosted concurrency. Sync the
implemented Agent Note (EN/ZH) so the decision record no longer says Windows
is fixed at 8, and revise the same-partition-count alternative accordingly.
Keep recognized code fences syntax-highlighted while assistant text streams. Preserve completed Shiki token lines across chunks, mirror token styles and CRLF handling, and retain plain rendering for unsupported or math-like fences.
Add unit, DOM-parity, and keyless assembled-Web coverage for the streaming-to-settled transition.
Closes#1499
Keep the 4-partition coverage profile, split the monolithic windows-native
job into smaller required jobs (build, coverage, native-tests) plus a
non-blocking observational job. Update ci-workflow.spec for the new topology.
Under high self-hosted concurrency, 8 partitions per Windows native job
triggered vitest fork worker startup timeouts. This branch lowers Windows
coverage to the same 4 partitions Linux uses, trading some single-job
coverage wall time for lower process-creation pressure.
CI hit the same dropped-fill race in lifecycle-chrome's slash-menu
sequence that the folder scenario hit: fill()'s single-task select-all +
edit lands on a Lexical selection that has not absorbed the DOM
selection after a trigger-menu interaction, so the previous draft
survives and poisons the next test. Promote the per-key gesture to
support.ts and use it at both proven-fragile sites.
The base-mounted projection cache's write-behind forces session-log flushes
at cache-chosen times, splitting packed chunk rows and changing the durable
JSONL batching the keyless headless and sdk replay fixtures pin. Neither
profile exposes a session-listing surface — the one-shot runner and the SDK
protocol — so both bundles disable the base row, restoring the pre-base
behavior the fixtures were recorded against (the same pattern acp-app uses).
The pinned prompts were recorded on master before this branch's
file-reference guidance rewrite; refresh them so the pin carries the
directory-aware wording the assembly now produces.
Directly after a chip deletion, fill()'s single-task select-all +
insertText lands on a Lexical selection that has not absorbed the DOM
selection yet and is dropped, leaving the previous draft in place. Real
keystrokes leave room for selectionchange between keys, matching what a

The Windows x64 installed-wheel job timed out while waiting for initialize even though the same head passed on rerun. Exact packaged-runtime VM evidence showed a 6.47-second first cold handshake and 2.69-2.94-second warm fresh-home handshakes, leaving too little variance below the public 10-second default.\n\nRaise the independent initialize default to 30 seconds in both Python SDK configuration layers. Ordinary turn and shutdown timeouts remain unchanged, callers retain an explicit override, and tests plus paired documentation pin the public behavior.
Run the GitHub Windows runtime leg under the runner’s native PowerShell instead of inheriting the POSIX Bash body. POSIX and Windows now own explicit output resolution, virtual-environment setup, environment scrubbing, and keyless/live black-box commands, while portable build commands continue to use each runner’s default shell.
Put the pinned uv installation on the GitLab Windows job PATH before either the smoke or release builder invokes it. Reject a runtime executable whose basename does not match the selected platform manifest, and reject Intel macOS at platform selection instead of reporting a misleading missing artifact.
Add a complete PowerShell path to the published Python tutorial and record the three-phase shutdown-time bound in the Windows runtime decision. Workflow, Python, and bilingual documentation tests pin the resulting behavior.
Record win-x64 as the sole Windows Python carrier: node24-win-x64 builds a py3-none-win_amd64 wheel with dsh.exe, rg.exe, and both ConPTY addons; Windows arm64 remains explicitly unsupported. The note also pins native build ownership, shell-free pnpm launch, installed-wheel keyless/live gates, and the PowerShell-specific minimal snapshot.
Update the active SEA, sole-launcher, profile-runtime, installed-wheel, and publication decisions from three runtime wheels to four, preserving their existing rationale while linking the Windows extension. Contributor and runtime references now state the exact target, filenames, sidecars, snapshot ownership, and five-wheel release set in both languages.
Make the checked-in minimal SDK overlay disable both one-shot shell rows and mount exactly one persistent PTY stack: Bash on Linux/macOS and PowerShell on Windows. The SDK server, explicit dsh home, persistence, editor, timeout, and reduced tool catalog remain unchanged.
Update the runnable example and tutorial to list Windows x64 as supported, describe the platform-selected shell, and remove the obsolete POSIX-only restriction. This keeps the documented first Python task executable through the packaged Windows dsh profile instead of advertising a Linux-only overlay on a Windows-capable SDK.
Add node24-win-x64 to the required pull-request and public-release matrices on a native windows-2025 runner, and publish the same win_amd64 artifact from the GitLab tag pipeline. GitHub uses Git Bash for the shared release script while selecting the Windows venv's Scripts/python.exe explicitly; the Linux and macOS legs retain their existing commands and native checks.
Run the complete installed-wheel keyless suite and the trusted two-turn DeepSeek smoke on Windows exactly as on the existing targets. Make the minimal blackbox choose persistent PowerShell on Windows, keep advanced and restart snapshots platform-stable by disabling both one-shot shell variants, locate the generated dsh.exe console command, and validate text lines without assuming POSIX newlines.
Workflow tests pin the four-target matrix, Windows runner and wheel tag, cross-platform venv selection, GitLab publication dependency, and full blackbox invocation. The existing POSIX minimal snapshot changes only its platform-neutral prompt wording; Windows owns a separate model-visible snapshot.
Add node24-win-x64 as the only supported Windows runtime target and publish it as a py3-none-win_amd64 wheel containing the conventional dsh and ripgrep .exe payload names. Keep Windows ARM64 rejected explicitly so Python cannot claim a carrier that CI and release automation do not build.
Teach the pkg builder to require a native x64 Windows host, validate both node-pty ConPTY addons, copy @vscode's win32 ripgrep executable, and recognize pkg's .exe output. Extend runtime resolution, wheel staging, payload validation, and the preset closure check so the Windows-specific PowerShell plugins and sidecars fail loud when omitted.
The sidecar resolver now maps a packaged main.exe to main-rg.exe; focused TypeScript and Python tests cover that name, the win_amd64 manifest, x64-only host selection, complete wheel payload, ConPTY inventory, and platform-conditioned plugin closure.
The keyless max-token smoke carried a disable overlay that reproduced the removed private carrier's reduced tool roster. That legacy roster is now owned by the standalone sdk-minimal profile, so mutating the full sdk profile hides the application the SDK actually ships.\n\nLaunch sdk without a patch for both the successful and invalid-config paths. The separate sdk-minimal process test continues to pin its exact platform-selected two-tool request.
The startup test helper always constructed an explicit sdk profile, so coverage never exercised apply's supported default-config path even though runtime behavior depended on it.\n\nPass Config objects through the helper and default them to an empty config. The existing startup and help tests now prove sdk defaulting, while the explicit sdk-minimal case remains covered.
Stop narrowing the standalone DeepSeek adapter to a DSH_MODEL-derived one-entry catalog. The direct adapter already accepts model ids outside its advisory catalog, so retain only the DSH_CONTEXT_WINDOW fallback and let the JSON-RPC initialize model be the single runtime selection.
Remove model mirroring from minimal.py and the packaged smoke. The keyless process now initializes deepseek-v4-pro without DSH_MODEL, while the packaged scenario continues to use its unlisted smoke-model; together they prove both cataloged and arbitrary SDK model arguments reach the adapter directly.
Update the bundle, tutorial, SDK/example references, and owning Agent Notes to keep DSH_MODEL only as minimal.py's optional default input, never as a second value callers must synchronize.
Record sdk-minimal as the narrow repository-owned exception to base-first profile composition: callers still launch only dsh and cannot provide an arbitrary Cordis tree, while the shipped bundle may own a complete explicit roster. Cross-link the launcher, profile-bundle, Python-runtime, minimal-agent, snapshot, and telemetry decisions; the supersession audit keeps each older note active because its remaining rationale is independent.
Update the CLI, architecture, Python tutorial/reference, example, runtime-wheel reference, and bundle documentation. The docs distinguish the full sdk profile from sdk-minimal, explain explicit-home/plugin/patch customization, state the minimal permission and persistence choices, and retain the separately packaged web profile and frontend assets for direct dsh use.
Correct dsh-base descriptions to cover base-backed profiles, make SDK startup configuration visible in the generated config catalog, add sdk-minimal to the module graph, and regenerate the base-composition graph. English and Chinese pairs are re-recorded at the exact reviewed contents.
Make minimal.py select the shipped sdk-minimal profile directly and pass its selected model into the profile-owned adapter catalog. The Python SDK still starts only the bundled dsh CLI with an explicit Harness home; it no longer supplies an invocation overlay for this mode.
Drive both the source keyless process test and installed-wheel smoke through the same named profile. The keyless test pins the generated profile manifest and exact two-tool model request, while the packaged smoke keeps the persistent-shell, editor, session-log, and model-visible snapshot evidence.
Delete minimal.patch.yml and the unused complete-config/replay fixtures. Their composition now has one owner in @deepseek-ai/dsh-sdk-minimal, so the example and tests cannot drift into separate launch trees.
Add a startup-only sdk-minimal template whose sole bundle inserts the complete JSON-RPC agent tree over the empty profile root. The roster is an explicit composition allowlist: it contains one DeepSeek adapter, the minimal agent spine, persistent Bash, the string-replace editor, local execution, and JSONL persistence, while dsh-base and Web remain absent.
Reuse the SDK app startup provider so the new profile retains help, stdin EOF, and bounded launcher shutdown semantics. Make that provider render its configured profile name, which keeps both sdk and sdk-minimal help truthful without duplicating process lifecycle code.
Register the package in the CLI closure, TypeScript graph, lockfile, Knip policy, and bilingual bundle references. Exact manifest, row-roster, profile-template, config-dump, and HMR tests make later additions visible instead of relying on a blacklist.
Resolve the installation fallback generation before locking and return immediately when every required symlink or packaged proxy is complete. Parallel SDK rollouts sharing an initialized DSH_HOME therefore do not queue on profiles/node_modules.lock.
Missing or stale entries still acquire the cross-process writer lock, recheck the generation, and repair under exclusive ownership. Tests hold the lock to prove the steady-state bypass and verify that a partial repair retains already-correct siblings.
Give the SDK JSON-RPC server a per-root tool filter and let deployments mark the configured persona as the complete system prompt. The checked-in minimal overlay now names only bash and str_replace_editor, so later global tools and unrelated guidance from dsh-base cannot appear implicitly.
Keep the shared SDK host services and packaged Web capability intact. Only workspace instructions, compaction, and the conflicting one-shot Bash row remain disabled. Unit coverage pins the configuration paths, and a real dsh profile smoke proves the assembled prompt and exact two-tool request.
The packaged dsh launcher must expose installation modules to profile-local plugins without writing symlinks into pkg's virtual filesystem. The first review fix selected ESM exports correctly in ordinary Node, but real carrier execution exposed package metadata and VFS behavior that a synthetic tree did not cover: executable and declaration packages have no import entry, legacy main fields rely on Node probing, and pkg's Windows VFS prevents filesystem package-scope resolution from seeing exports such as zod/mini and @google/genai/web.
Resolve explicit exports directly from each installed manifest with the maintained resolve.exports package under Node import conditions. Publish only package-local candidate files that exist, reject escaping or malformed targets, preserve the package installation URL without realpath, and keep Node's legacy resolver only for exports-less packages. This avoids pkg filesystem package lookup entirely while retaining fail-loud behavior for broken runtime entries.
Add regression coverage for import-only, nested, symlinked, zod-style, and genai-style condition maps; unavailable and types-only entries; invalid and escaping targets; executable/declaration packages; extensionless main; and legacy index fallback. profile.ts remains at 100% statements, branches, functions, and lines. Update the bilingual package and Agent Note contracts, replace the runtime dependency and generated notice, and regenerate the lockfile through pnpm.
Resolve packaged profile proxies with Node ESM import conditions from each package installation, and fail loud when an explicit runtime export or legacy main entry is missing. Serialize the shared profile fallback under the existing cross-process writer lock so concurrent dsh processes cannot observe partial proxies; either carrier now replaces the other carrier’s managed entry without manual cleanup.
Give Python initialize its own 10-second default bound and name the selected profile in timeout diagnostics, while leaving ordinary agent turns unbounded by default. Package the dynamically resolved web frontend and skill-badge assets so the runtime wheel’s normal dsh profiles do not depend on pkg static-discovery accidents.
Rewrite the root launch rule and every active stale SDK-runtime note to the shipped dsh profile architecture in both languages. Focused tests prove import-only and transitive package exports, lock contention, cross-carrier transitions, missing-entry failures, asset inventory, and bounded initialization.
Document dsh as the only application launcher across architecture, CLI, SDK, app-boot, Python package, contributor, tutorial, and example references. Explain explicit home selection, profile and patch precedence, persistent external plugin installation, the Node-free runtime path, and the absence of complete-config or ~/.dsh fallbacks.
Record the Python profile-runtime decision and update the active naming, installed-wheel, and SEA packaging notes with precise supersession. Regenerate the configuration catalog and module graph after deleting the carrier, update both reviewed languages and pairing records, and classify the retained standalone Cordis files as lower-level test fixtures rather than launch interfaces.
Migrate the packaged-runtime smoke inventory from complete Cordis trees to the sdk profile plus ordered patches. Preserve the focused minimal and advanced behaviors, update the generated durable snapshots for explicit permission events and the smaller RunResult, and keep worker, MCP, ripgrep, PTY/editor, direct JSON-RPC, and real-provider coverage.
Add an installed-only external bundle scenario that invokes the wheel's dsh plugin command with a local file package, verifies profile manifest reconciliation, imports @deepseek-ai/cordis as a peer, asserts the packaged proxy returns the exact host Context instance, and proves its system-prompt contribution reaches the model. Migrate the repository source e2e and runnable minimal example to the same profile grammar.
Replace complete-config, session_root, runtime-bin, bridge-bin, and public argv override options with dsh_bin, profile, ordered patches, and dsh_home. Resolve executable/home/patch/cwd paths before spawn, select the sdk profile by default, and fail before launch unless dsh_home or non-empty DSH_HOME is explicit; Python never inherits ~/.dsh silently.
Remove Python-owned DSH_CORDIS_CONFIG, DSH_SESSION_ROOT, and DSH_CWD injection and drop session_root from RunResult. Keep arbitrary argv only as an underscore-prefixed fake-runtime adapter, retain provider/model/token and process controls, and append subprocess stderr to initialization JSON-RPC errors so profile boot failures name their actual plugin cause. Unit and carrier tests cover both exe and Node modes.
Make the zero-code dsh-python-runtime-closure depend on the real @deepseek-ai/dsh application and every required profile peer, then package apps/cli's built bin instead of the deleted Python carrier. Rename executables to deepseek-harness-sdk-runtime-<platform>-<arch>, update wheel/platform/build workflow discovery, and install a Python dsh console command that requires explicit DSH_HOME before exec.
Include profile, bundle, preset, native addon, and shared-library assets needed by the full CLI. Remove the checked-in default cordis.yml and preserve the existing wheel distribution names, Python module names, sidecar validation, and wire identity. Runtime resolution and release tests pin the new artifacts and dev Node carrier.
Teach the profile installation fallback to use normal symlinks under Node and real ESM proxy packages under pkg. Each proxy records the source package version, mirrors its explicit runtime subpath exports, and re-exports the virtual /snapshot URLs, so built-in Loader rows and external plugin peers resolve one shared Cordis/module instance from an on-disk profile.
Keep proxy healing idempotent, reject foreign real directories, cover root and subpath imports in packaged mode, and expand AggregateError startup diagnostics so concurrent Loader failures retain their individual import causes. This is the reusable packaged-profile mechanism; Python-specific artifact wiring remains in the next commit.
Delete @deepseek-ai/dsh-sdk-python-runtime and its packaged-bin entry now that Python uses the repository's dsh application launcher. Remove the package's project reference, Knip entry, workspace-policy exception, executable allowlist entry, and README-model classification together so no tooling preserves the old exception.
This commit is deliberately mechanical: it removes the obsolete package and gate accommodations without introducing the replacement launch behavior. The following commits add the packaged dsh runtime and Python profile API, keeping the architecture change separate from deletion noise.
The read-image-reencode lane feeds a 16-bit gradient PNG through the
shipped app: pass-through is impossible, the master converts down the
opaque JPEG ladder, and the 640,000-pixel request budget re-encodes a
downscaled request version — the projection the byte-identical tiny
fixtures never exercised.
Master dimensions move from a 2048 long-edge rule to a total-pixel
budget (normalizedImageMaxPixels, default 2048x2048) with an 8192
long-edge cap, so extreme aspect ratios keep short-edge resolution.
The shared quality ladder and lazy execution move to encoding.ts,
review-round doc fixes land across attachment and llm packages, and
the superseded facts in the unified-image-pipeline note now describe
the shipped routing.
Field test: the model received a bare '@niulai/' and guessed a user
mention — the guidance section was present but said only that @-prefixed
paths are files, never covering the trailing-slash directory form, the
workspace-relative root, or the quoted spelling. Rewrite the section to
name all three; the section's presence conditions and every consumer
pin the constant, so nothing else moves.
CI's snapshots lane timed out waiting for the folderx candidate: the
fixture directory was created after connectFreshWorkspace, racing the
Host's file index on a loaded runner. Land every fixture (and the
workspace directory itself) before the connect, and give the first
folder query a cold-start allowance.
A directory row in the @ menu had one verb doing two jobs: picking it
inserted literal @dir/ text and kept the menu open, so a user wanting
the folder itself never got a settled entity — the token kept its
trigger character and stayed editable, nothing like a file's atomic
chip.
Split the intents on the same row, mapped to shell-completion instincts:
row click / Enter settles the directory as an atomic folder chip (the
file chip's exact language; canonical @dir/ mention as its serialized
form — the { insert } arm the folder path never took), while Tab or the
row's trailing chevron drills: literal editable text, menu open on the
children. One new dimension carries it: candidate.drill advertises the
verb, InputTriggerPick.action reports it, ArbitrateKey gains 'tab', and
the keymap intercepts Tab only while a drill row is highlighted.
Covered by controller arbitration, MenuView chevron routing, the
ui-reference verb split, a keymap Tab-passthrough spec, and a real-
browser e2e driving all three gestures; menu golden refreshed for the
chevron and the fixture directory.
foldSurfaceTokens rebuilt the priced surface on every surface event: an
append allocated [...nodes, node] and a replacement copied the whole
array before splicing, charging every well-formed event O(surface) for
an atomicity property only malformed events need. Benchmarks put the
copy at ~99.9% of an append's cost (100µs at a 50k-node surface vs
0.1µs for pricing) with O(S²) accumulation over a session, inside the
synchronous session/event publication path.
Split the fold into the session core's planSurfaceEvent/applySurfacePlan
shape: planSurfaceTokens performs every fallible step against the
read-only surface, commitSurfaceTokens applies the plan in place and is
infallible by construction. _foldEvent plans first, runs the remaining
fallible anchor validation, and only then commits, so retry identity is
preserved by ordering instead of by allocation. Appends drop to
amortized O(1) (100.3µs -> 1.9µs at 50k nodes); replacements keep their
O(surface) findIndex but stop paying the extra full copy (21µs -> 4.2µs).
A new regression test pins the one hazard this introduces: an event
whose surface plan is valid but whose later anchor validation throws
must leave the priced surface and running total uncommitted across
repeated failures.
- The base-mounted projection cache's write-behind forces session-log
flushes at cache-chosen times, splitting packed chunk rows and collapsing
the persistence window the keyless acp transcripts pin. ACP exposes no
session-listing surface, so the automation profile disables the base row,
restoring the pre-base behavior the fixtures were recorded against.
- The windows coverage lane runs suites that read built lib/ output (the
webworker-packer image tests) and raced the build gate's tsdown writes
against a partial tree; every coverage gate now waits for the build gate.
Delete the 5-bit colour-count classifier and palette PNG branch that
misrouted high-frequency photographic JPEGs (issue #2885 images 23/24)
into an encoder 100x slower with 4x larger output. Both normalization
and request-image encoding now route by the decoded alpha fact alone:
opaque sources down a JPEG ladder and alpha sources down a WebP
effort-0 ladder, each at qualities 85/75/60. Byte budgets become ladder
targets: the downscale retry loop is gone and a ladder-exhausted encode
keeps its smallest output, while provider byte caps stay enforced at
the transmitting route. Request transforms move to request-image-v5.
The exact-shape fix added two filesystem-failure catch branches that only
fire on a race/permission fault the caller already guards against (the
session-dir readdir after an isDirectory() check, and the discovered-root
rmdir after the root was observed empty). Neither is deterministically
reproducible in-process, so tag both with the same reasoned v8 ignore the
sibling catch blocks already use, restoring per-file 100% coverage and the
symmetry between the parallel rmdir handlers.
Tighten the startup sweep to backend-generated name shapes and fix the tests
that had drifted from the SweepRoot-based API:
- Match roots by the exact `dsh-spill-<6>` mkdtemp shape and session dirs by
`session-<12 hex>` (DEFAULT_ROOT_RE / SESSION_DIR_RE), replacing loose
startsWith checks so foreign or fixture-shaped directories are never swept.
- Carry `SweepRoot { path, pruneWhenEmpty }` through SweepOptions so a discovered
prior-default root is removed once emptied while the active root is never
pruned; lstat each session entry so a symlinked session dir is not followed.
- Fix the tests to the SweepRoot API: import SweepRoot, correct the gatherRoots
override return shapes, build discovery fixtures with the real mkdtemp shape,
and route the warn-wiring test through a deterministic failure path.
The local spill backend never reclaimed its files, so configured roots
grew without bound and default per-process dsh-spill-* temp roots piled
up across runs. Immediate deletion is unsafe because persisted, resumed,
and forked sessions may still reference an older locator.
Add a fiber-owned, best-effort sweep that runs once after activation
(never delaying availability, awaited on disposal): it deletes regular
files older than cleanupPeriodDays (default 30; 0 disables) across the
configured root and prior default temp roots, prunes emptied dirs, and
skips symlinks/unknown entries. Every filesystem failure is contained
and logged, so the sweep cannot fail activation or a concurrent write.
preview-boot's hero wait was master's new textarea:enabled locator (the
conv refactor predates the Lexical composer); migrate it to the
data-composer-input surface like every other lane. Drop the unnecessary
DOMRect assertion oxlint flagged on the new Range stub.
- user-text.tsx enters ui-primitives' per-file 100% gate: replace three
regex-guaranteed impossible ?? fallbacks with asserted captures, make
the precedence sort a branch-free rank comparator, and pin the nested
recall-label ordering and the no-basename quoted-path fallback with
tests (100% statements/branches/functions locally).
- assembled-boot stubs Range.prototype.getBoundingClientRect: jsdom has
no Range geometry, and Lexical's selection reveal now reaches it in the
built-graph lane after the architecture merge (the unhandled TypeError
behind command-image-envelope and preview-boot).
The worker-preview pack landed on master declaring dsh.configTrees
against apps/cli/config/agent-presets, which this branch moved into
packages/preset/agent-presets/presets. The VFS mount and the worker-side
roster patch keep their paths; only the source directory follows the
move.
The spec landed on master before the roster gained the plugin-bundled
shipped root; its empty-roots harness now opts out explicitly, matching
every other exact-roster suite.
The Landlock packed-install rehearsal packed a hand-maintained list of
workspace tarballs. When dsh-llm gained the dsh-util-crypto runtime
dependency, the list stayed stale and npm tried to fetch the unpublished
release candidate from the public registry, failing both Linux master jobs
with E404 before confinement ran.
Read the current pnpm workspace inventory and traverse dependencies,
optionalDependencies, and required peerDependencies from the packed test
roots. Verify package identities, fail loudly on unresolved workspace names,
sort the closure deterministically, and leave native-family packages to the
existing mode-preserving native packer.
Cover runtime traversal, optional-peer exclusion, native filtering, and
invalid workspace metadata. Remove the obsolete vendoring exact edit for the
deleted manual list so future runtime workspace additions are included by
their manifests instead of becoming post-merge CI failures.
Unix PowerShell emits cursor-position requests while PSReadLine starts and
redraws prompts. The subprocess PTY is only a transport, so those requests
went unanswered. Startup could then accept the dsh> literal echoed from its
setup source as a rendered prompt, and later sends were lost or clipped.
Feed raw PTY output into a zero-scrollback @xterm/headless state machine and
write generated replies through the provider-owned terminal handle. Drain
replies before caller input, repeat foreground inspection when terminal
activity races the sample, and retain send ownership until parser and reply
work quiesce. Coalesce raw chunks behind one active parser write so large
Windows output cannot create thousands of queued parse callbacks.
Publish pwsh only from backend stdin_read evidence and start one timeoutMs
deadline before the complete startup retry loop, so inferred-idle follow-ups
cannot reset the bound. Dispose the emulator when the
terminal or cleanup fails. Document the fail-loud ConstrainedLanguage path
and add focused coverage for split queries, reply ordering, foreground
resampling, failure containment, batching, timeout, and disposal.
* test(python): exercise installed wheels as black boxes
Add an installed-wheel mode that refuses source/editable imports, repository working directories, mismatched SDK/runtime versions, unpinned runtime dependencies, and executables outside the installed runtime distribution. The mode resolves the wheel-owned executable itself, so callers cannot accidentally prove an explicit checkout artifact.
Add a real-API scenario that drives two tool-using turns through the public synchronous SDK, verifies the file bytes outside the agent, checks completed turn/tool events and persistence, and projects provider failures without retaining credential-bearing error text. The existing deterministic scenario set remains the keyless behavior oracle.
Refs #2952.
* ci(python): require installed-wheel checks on every release target
Move the complete deterministic runtime scenarios behind construction and clean installation of the SDK and matching runtime wheels. Each native leg runs outside the checkout with source-resolution environment variables removed; Linux manylinux smokes assert the same installed provenance.
Expand the required pull-request call from Linux x64 to Linux x64, Linux arm64, and macOS arm64. Trusted heads receive only DEEPSEEK_API_KEY_EXTERNAL for a fail-loud live two-turn smoke on each carrier, while fork and Dependabot heads retain the full keyless path without exposing secrets.
Pin the reusable secret declaration, matrix call, aggregate dependency, untrusted-head condition, and live/keyless commands in the workflow contract test.
Refs #2952.
* docs(testing): make installed wheels the Python CI authority
Record the clean-wheel provenance boundary, complete keyless scenario set, trusted real-API contract, secret handling, and three-target required topology in a new implemented testing decision. Update the SEA distribution and portable-CI authorities plus the Python contributor reference to describe the same current state.
Archive the fully superseded Linux-x64-only decision after consolidating its rationale and alternatives into the new owner. Preserve its bilingual triplet as a sealed historical snapshot and redirect every active current-state reference.
Refs #2952.
Move the shared module-reload policy into dsh-base by inserting its HMR row disabled, then remove the redundant disabled overrides from Web, headless, SDK, and ACP. No shipped profile enables server module reload; live profile patch watching continues through the launcher-owned config-only fallback, and browser client HMR remains a separate mechanism.
A later profile layer can opt into source-module reload explicitly with disabled: false while retaining the base root configuration. Composition tests cover every shipped mode and the explicit enable path, and the bundle references plus launcher Agent Notes document the resulting ownership and safety rationale.
Set DSH_E2E_MAX_WORKERS=4 for the credentialed e2e workflow and pin that environment contract in the workflow test. Profile-launched SDK and ACP scenarios each boot a complete subprocess tree, so the previous file-level fan-out could multiply process and provider pressure far beyond the runner's useful concurrency.
The bound changes scheduling only: every e2e file still runs, the Vitest configuration retains its explicit override knob, and local callers can choose a different positive worker count when their resources allow it.
Regenerate the configuration catalog and module graph after replacing standalone application packages with dsh profile bundles and renaming the private Python carrier. Update built-bin coverage to launch the shipped sdk and acp profiles, assert retired bins stay absent, and keep the Web golden text aligned with the same assembled runtime.
Clarify that headless is a startup profile whose patches freeze after boot. This commit is projection and verification work: it contains no application implementation, and every generated document is produced from source committed earlier in the series.
Update workspace manifests, the lockfile, Host project references, Knip inputs, package constraints, vendoring rewrites, and Python runtime build/smoke scripts for sdk-app, acp-app, and @deepseek-ai/dsh-sdk-python-runtime. Add the ACP hook packages to the dsh dependency closure so installed profile materialization resolves the same plugins as source workspaces.
Keep Python distribution outputs deliberately unchanged: the wheel modules, executable names, and smoke targets retain their public identities even though their private npm carrier moved. Constraint fixtures pin the new package locations and catch missing application dependencies on every platform.
Add verify-application-entrypoints to the top-level gate graph. It inventories executable sources and package bins across apps, packages, and examples; rejects unclassified launchers including root-level js/mjs/cjs/ts files; and permits only the dsh CLI plus the explicitly private Python runtime carrier exception.
Update repository, architecture, CLI, and naming records to state the same rule: Node consumers select a dsh profile instead of invoking application-package bins, and no compatibility aliases remain. Fixtures prove both allowed classifications and representative escape attempts, making the architectural rule mechanically enforceable.
Rename the relocated npm workspace to @deepseek-ai/dsh-sdk-python-runtime and the runnable example to python-sdk-agent, then update every owning English/Chinese document, test, and packaged-runtime reference. Remove the obsolete standalone bin while retaining the carrier entrypoints used to assemble the wheel runtime.
This is intentionally a naming and ownership change, not a Python SDK migration. The public deepseek_harness_sdk and deepseek_harness_runtime module, wheel, executable, environment, and wire behavior remain unchanged. Documentation records that this private carrier is the temporary sole non-dsh application exception and will move to profile launch later.
Regenerate the four TypeScript SDK replay scenarios after switching their subprocess to dsh --profile sdk. The fixtures now project profile-owned runtime context, tool composition, nested-child persistence, and the opt-in DeepSeek session-log acceptance event while preserving each scenario's final response and file assertions.
This commit contains only committed snapshot outputs. Separating them from the SDK implementation keeps protocol/API review focused and makes the model-visible consequences auditable as generated evidence.
Replace the TypeScript SDK's public arbitrary command/argv launch surface with the same-version dsh CLI, a named profile, ordered per-launch patches, optional process cwd, and explicit Harness home selection. Installed consumers use the built CLI; clean source checkouts use the package's src/bin.ts through an absolute tsx/esm loader and a source-only patch that omits build-generated Typert loading.
Materialize explicit or inherited environments at spawn time, keep profile-internal patches below caller patches, and resolve every caller-relative path before the child starts. The SDK subagent provider validates its optional CLI and patch files at plugin load and requires an isolated absolute child home.
Treat JSON-RPC initialize as the Loader-owned readiness point: Loader settlement joins entry imports, fiber lifecycle work, and synchronous effect registration, so the server needs no scheduler tick. A delayed profile entry registers a private adapter before initialize resolves, proving caller-supplied plugin routes are visible without fallback.
Update sdk-app ownership, server diagnostics, TypeScript SDK examples, nested-loader coverage, and session-upload replay layering together. The following commit contains only the regenerated SDK transcripts, keeping this API and lifecycle change directly reviewable.
Move examples/jsonrpc-agent to examples/python-sdk-agent and packages/examples/jsonrpc-demo to packages/sdk/python-runtime while preserving every file byte-for-byte. The directory placement now reflects the example's Python-distribution role and the private runtime carrier's SDK ownership.
This commit deliberately keeps the old package names, commands, configuration, and snapshots inside their new directories. All 42 files are 100% renames; API/profile migration and naming changes follow separately so reviewers do not have to disentangle behavior from filesystem movement.
Regenerate the ACP composition graph and committed replay outputs from the assembled dsh base plus acp-app profile. The updated logs, system prompts, tool schemas, and stdout projections capture the same scenarios after shared plugins move out of the retired demo package and into profile-owned composition.
There is no runtime source in this commit. Keeping generator-owned artifacts separate lets reviewers validate the behavioral migration first, then inspect expected wire/model-visible consequences as a mechanical projection update.
Replace the standalone @deepseek-ai/dsh-acp-demo application with dsh --profile acp plus ordered example patches. The shipped acp-app bundle owns only the protocol bridge; every example overlay now targets shared dsh-base rows instead of copying a complete application tree.
Move launcher responsibilities into the ACP snapshot harness: it materializes profile patches, links required packages, reserves stdout for JSON-RPC, observes spawn and drain failures, and escalates process teardown deterministically. The relocated control-surface fixture and the ACP/subagent integration tests now exercise the real CLI/profile path.
This commit contains authored runtime, configuration, and test changes only. Generated transcript and projection churn is deliberately left for the next commit so reviewers can inspect the migration logic without hundreds of expected-output edits.
Move the ACP control-surface e2e, scripted LLM, and Cordis fixture out of the application package that later commits retire and into the runnable examples/acp-agent test tree. This gives the assembled dsh profile example ownership of its integration fixture.
This commit is intentionally mechanical: all three files retain their exact blobs and appear as 100% renames. Imports and launch behavior are updated only in the subsequent ACP migration commit, keeping reviewer-visible code changes separate from file movement.
Introduce @deepseek-ai/dsh-acp-app as the thin application layer for the built-in acp profile. It contributes only the ACP protocol bridge and profile metadata; dsh-base remains the single owner of shared agent composition, providers, persistence, permissions, and tools.
Wire the bundle into CLI resolution, catalogs, workspace configuration, and built-bin coverage. The focused bundle and startup tests prove that base plus acp-app exposes automation sessions while keeping stdout reserved for ACP JSON-RPC.
Introduce @deepseek-ai/dsh-sdk-app as the thin application layer for the built-in sdk profile. The bundle contributes the JSON-RPC server and startup-only profile metadata, while dsh-base continues to own the shared agent, provider, persistence, and tool composition.
Publish ctx.appReady from the launcher only after the Loader tree and launcher-owned setup succeed. The stdio lifetime binding leaves stdin unread until the protocol transport claims it and defers EOF exit 0 until readiness commits, so early protocol frames remain buffered and a racing startup failure remains the nonzero process outcome. Fiber disposal cancels both pending lifecycle listeners.
Register the bundle in the CLI resolver closure, generated configuration catalog, workspace graph, and built-bin smoke. Startup tests prove that base plus sdk-app exposes the SDK server without taking ownership of shared runtime plugins; focused and built-bin regressions cover early input, EOF readiness, and startup-error precedence.
Add a patchReload field to built-in profile metadata and carry it through CLI profile resolution into app boot. Live profiles install the existing patch watcher; startup profiles freeze every layer after boot and apply later edits only on the next launch. Missing or invalid metadata fails before the plugin tree starts.
The implementation keeps reload policy with the profile that owns it instead of inferring behavior from an entrypoint. Unit tests cover metadata validation and both lifecycle modes, while the CLI and app-boot references document which built-ins are live versus startup.
Record the final architecture before any runtime or file-layout changes. The decision makes named dsh profiles the only supported Node application launch path, gives TypeScript SDK callers ordered profile patches for per-launch customization, and retains the packaged Python runtime as an explicitly temporary exception with a later migration obligation.
Keeping this decision in a documentation-only commit gives every following commit one stable naming, lifecycle, and compatibility reference. The English and Chinese notes and their pairing record enter together.
- stop attributing the 45-case helper/Node divergence to the path port spec,
which pins only the Node-facing port to Node
- keep the divergence measurement as provenance, without a dead owner
- fix the path corpus comment so it does not claim divergence from the spec
that asserts equality
- drop the v2 generation stamp from the cordis mount fallback test
- restate the watcher refusal rationale in current-state terms
- re-record the ui-workspace bilingual pair after rebase
Remove dead design-session citations, change narration, indexical
stamps, and review-adjacent justification found by the
dsh-trim-cot-leakage recall batteries in prose that landed after the
last purge. Bilingual README pairs are re-recorded.
Config catalog, module graph, event producer-consumer tables, and
third-party notices regenerate over the webworker surface; the oxlint
rule fingerprint and the ui-renderer NodeNext import face follow.
One Vite build emits dist/index.html and dist/preview.html sharing every
chunk; the only difference is one prepended bootstrap entry whose module
connects the worker host, so the page from the stock entry onward is the
served startup chain verbatim. The dist moves to a relative base so the
preview mounts under any static directory, and the served form anchors
deep SPA-fallback paths with a rendered <base href="/">. The preview-boot
e2e serves the real built pages, packs the VFS image when absent, and
holds the boot line's lowering contract, the interactive hero, and a
clean page-error channel in headless Chromium.
The webserver renders a boot-readiness tail after the injection rows and
AppWebEntry.run awaits the __DSH_BOOT_READY__ deferred before reading any
injected state. Whichever bootstrap applies the injection table settles
the deferred - the served renderer resolves it inline, an asynchronous
bootstrap installs it ahead of the entry module and settles it with the
handshake - so both deployments run one startup chain and a failed
handshake surfaces on the boot page instead of proceeding on missing
globals.
Buy the grammar, own the execution: @yarnpkg/parsers parses the command
line - aliased at bundle time to its shell entry so the root barrel's
syml/js-yaml closure stays out of the worker - and a VFS-backed evaluator
with a coreutils command table runs it inside the worker host. Each shell
process is a real child WebWorker spawned from the same bundle (the first
frame decides the role), so the TERM-then-KILL ladder is real - TERM
requests, KILL terminates the worker - and the file face stays
asynchronous end to end, since the deployment target serves no COOP/COEP
headers and SharedArrayBuffer never exists there. node:child_process
reports through the ChildProcess surface the subprocess service consumes;
execSync, execFileSync and fork refuse, and node-pty stays stubbed.
Two private experimental packages run the whole harness tree inside one
dedicated Web Worker. dsh-experimental-webworker-runtime owns the in-memory
VFS (BigInt stats with per-path identity and strictly increasing mtimes),
the CommonJS wrapper loader over a lazily-evaluated builtin table whose
shims typecheck against Node's own module types, the postMessage tunnel
speaking plain HTTP, the AsyncLocalStorage runtime, and the worker
assembly. dsh-experimental-webworker-packer lowers every module body at
pack time against the shared wrapper contract, sweeps the profile closure
by static reachability, and writes a deterministically gzip-compressed tar
the worker inflates through the browser's native DecompressionStream while
it downloads.
The old backdrop overpainted a folder reference's trigger character with
IconFolderClose16; the Lexical rewrite kept the data-ref-appearance
attribute but nothing consumed it, so the composer showed a bare blue
token while the sent bubble carried the icon. A Lexical text node cannot
split out its trigger character for overpainting, so the glyph renders
as an icon prefix instead: a currentcolor mask of the same asset before
the intact literal token. The Lexical note's behavior line follows.
Keep the active implemented and proposed Agent Notes current with the
renamed ToolCallId brand: branded-ids, content-block-vocabulary,
approval-seam, tool-output-spill-files, and task-surface, in both
languages, with re-recorded .i18n.yaml pairing records.
Review-round hardening of canonical admission:
- passthrough now requires a single-frame source free of EXIF/XMP/IPTC
metadata, so location/device metadata never enters durable storage and
stored dimensions always describe the perceived pixels; animated WebP joins
GIF on the always-re-encode path (first frame only)
- SourceImageInfo records orientation-applied dimensions, keeping source and
stored raster on shared axes for coordinate mapping
- validateImage runs a canonical-encoding dry run, so a validated batch can no
longer be refused mid-write by the byte target (no partial writes)
- read_image names per-axis multipliers when rounding splits the two ratios
and maps IMAGE_TOO_LARGE to actionable downscale guidance
READMEs (both languages) describe the wide source envelope, the canonical
encoding and its fixed encoder parameters, and read_image's downscale
envelope; tool/config catalogs regenerate for the new schema and Config
fields. The read-image-dimension scenario now pins the acceptance the old
2000px admission cap refused: the 2001x1 source is admitted and stored
byte-identically, so the fixture stays platform-independent.
The canonical ref serializes mediaType, width, height, bytes in the order the
pre-canonicalization store used, so existing session-log fixtures and logged
histories keep byte-identical reference JSON.
When the attachment store's canonical encoding shrinks the file on disk, the
read_image envelope names the original dimensions and the multiplier that
maps coordinates measured on the attached image back onto the file, and the
output schema carries sourceWidth/sourceHeight for programmatic callers.
Admission now validates a wide source envelope (32MiB, 100MP, 16384px per
side) and persists a canonical encoding instead of refusing large sources:
EXIF orientation baked in, metadata stripped, long edge downscaled to the
configured canonical target (default 2048px), PNG palette for alpha/PNG/GIF
sources and a fixed JPEG quality ladder (85/75/60/45) until the canonical
byte target holds (default 1MiB). In-budget PNG/JPEG/WebP passes through
byte-identically so equal sources keep deduplicating to the same content
address; GIF always re-encodes to the PNG of its first frame, pinning the
first-frame meaning providers apply. Encoder parameters are fixed by design;
only the canonical budget is deployment configuration.
AttachmentStore.saveImage now resolves SavedImageAttachment: the durable
reference paired with the submitted raster's intrinsic facts, so a store may
persist a canonical re-encoding while callers keep the source dimensions for
coordinate mapping. saveImages keeps returning refs; every fake store and the
cordis API catalog follow the new signature.
The user-bubble decorator rendered every plain run through the
block-level MessageText div, so a decorated single-line message broke
into one line per run and the space between two tokens rendered as a
blank line. The queue dock's read-only row printed row.preview verbatim,
showing the wire session form (@[label](dsh-session:...)) instead of a
readable label. Both predate the Lexical composer; the logged model text
was correct in both cases.
One shared inline projection (reference/user-text.tsx) now owns sent
user text for the bubble and the queue row: plain runs are spans with
white-space policy left to the consumer (bubble pre-wrap, queue nowrap),
and a highest-precedence rule folds the wire session form to its label
chip, shielding the URI from the bare-token scan. The queue edit field
keeps the literal sent text. user-text.client.spec pins the inline
guarantee and every fold rule; queue-actions.e2e locators move to
row-container matching (the projection adds one span layer).
Exposed by this branch touching rescope-vendor.ts, which runs the full
rescope check: the knip-logger-console exact edit targeted the
packages/util/home knip section that #2758 deleted (drop the edit), the
zh vendoring-cookbook anchor predates the rescope.zh.md link
localization (follow it), and the new shipped-root.spec.ts joins the
files whose bare 'cordis' tokens are preset ids.
The files constraint tables gained per-package expectations on master
while this branch changed two files lists: apps/cli no longer ships
config/, and dsh-agent-presets ships presets/ (ordered where the
expected-files derivation places extras).
The documentation site deployed on every master push, with no reviewer and
no version check, while npm, PyPI, and the public source repository all
advance only at a release tag. The Pages site is reachable without
authentication, so a merge published documentation ahead of every artifact
readers could obtain.
docs-pages.yml now declares workflow_dispatch alone and verifies the ref
through the gate npm publication already runs, so the site and the npm
sequence share one definition of a released version.
Review asked why the launcher special-cases one plugin's row. It no
longer does: the four shipped compositions move into the package
(presets/, in files), dsh-agent-presets resolves its own shipped root
and prepends it before configured roots (includeShippedRoot, default
true, opt-out for bare-machinery embedders), and the per-composition
derived patch, its spec, and the dump layer are deleted — profile-boot
and dump-config return to plain layer stacking. The always-load
guarantee now rides the schema default instead of patch ordering, so a
whole-config replacement keeps the shipped set and the squash, reload
freeze, and dump divergence stop being possible.
Gate globs, the web scaffold, and both preset browser lanes drop their
hand-fed shipped roots; the roster e2e keeps asserting configured roots
beside the shipped four against the built lib.
Fixes#2863.
The Windows native coverage lane was hitting Vitest's 30s per-test
ceiling on slow subprocess/ACP fixtures. Doubling the per-test budget
absorbs cold-start and process-teardown jitter without changing the
assertions or the job-level 120-minute cap.
python-release.yml only triggers on workflow_dispatch, so build.if:
github.event_name == 'workflow_dispatch' is always true and redundant; remove it
(the exact event set is already pinned in the spec). Update the spec assertion
accordingly.
Address PR #2875 review:
- Re-record python/development.i18n.yaml (corpus verify-translation-pairing was
out of sync after editing development.md/zh.md) and the 2026-08-11
python-publication-workflow pair after the dry-run wording tweak.
- Tighten the python-release spec assertion to the exact event set
(['workflow_dispatch']) instead of not.toHaveProperty('pull_request').
- Fix the 'dry-run run' wording in development.md and the note.
Corpus-wide verify-translation-pairing (1001 pairs) and note-format (594) pass;
ci-workflow.spec.ts 14/14.
The static gate (translation pairing) failed on a pre-existing master note:
2026-08-20-composer-edit-range-from-selection.zh.md:17 linked the zh target with
the en .md path. Point it at the .zh.md target and re-record the i18n hash. This
unblocks the required node 24 / static gate (it is not part of the python-release
gray-check change but sits on the same PR's CI path).
An intermediate cache iteration made cachedSnapshot async, which forced
listProjectionsFor onto a multi-line async signature; the final design
kept the sync read but the formatting residue stayed. No behavior
change.
The per-record contract test forced readFile to fail via chmod 0o000,
which is a no-op on win32, so the readRecord catch stayed uncovered on
the windows native coverage gate. Route record documents without an
isFile pre-filter: a directory where the document should be throws
EISDIR on every platform, and readRecord's existing contract already
reads an unreadable document as absent. Drop the win32 skip.
Review follow-ups: enumerate the derived shipped agent-preset root in
apps/cli README/reference dumps and the profile-boot module JSDoc
(bilingual pairs re-recorded), correct the stale AppCLIEntry/distIndex
analogy in the web scaffold and the shipped-root cross-reference in the
web preset e2e, drop the write-only ComposedProfile.rows field, and make
the Agent Note describe the dump path as sharing the derivation rather
than the builder.
Master's #2844 asserted composer recovery through a textarea locator the
Lexical composer no longer renders; the merge carried it in silently and
the CI web-snapshot lane timed out waiting for it. Use the same
data-composer-input wait the file's other cases already migrated to.
The master merge brought the doc-sync regenerations (locale-specific
paired document paths). Re-apply the zh-side link fixes to the agent
note and the session-projection intro, re-record translation pairing,
and keep the e2e event arrays as asserted literals like master.
The per-record rm in the cache spec hits an EPERM flake on windows
native (directory still draining); retry the recursive rm like the
subagent spec does. The unreadable-record probe is meaningless on
windows, where chmod 0o000 is a no-op; skip it there.
The reworked cache moved from the awaited coldSnapshot(id) to a sync
coldSnapshot(meta, events) whose write-back is fire-and-forget, and the
e2e fixture dropped the seeding call with it. The web bundle mounts the
cache again, so list rows read projection columns from stored rows only;
the one-shot and grandchild fixtures therefore lost their projections
column and the tree golden drifted. Re-seed both through the new API and
poll for the write-back to land.
Remove the pull_request:[labeled] trigger from python-release.yml so the
workflow no longer fires (and shows a gray skipped check) when a PR gets any
non-dry-run label. The credential-free dry-run validation is now manual-only
(workflow_dispatch with publish=false), preserving the validation capability
without a PR gray segment.
- python-release.yml: on is workflow_dispatch only; build.if is
github.event_name == 'workflow_dispatch'.
- ci-workflow.spec.ts: assert python-release has no pull_request event and the
simplified build.if.
- python/development.(md,zh.md) and 2026-08-11-python-publication-workflow note
(en/zh/i18n): describe the manual dispatch-only dry-run path.
Verification: ci-workflow.spec.ts 14/14, typecheck clean, note-format 585,
verify-translation-pairing consistent.
The boot-time agent-presets overlay replaced the composed roots with the
shipped root alone, so roots configured in a profile's cordis.patch.yml
vanished from the roster (externally reported in
deepseek-ai/deepseek-harness#3636). The overlay also froze the row's
boot-time config above every live reload and never reached the config
dump, which therefore showed roots the boot dropped.
Derive the roster patch from the current layers instead: prepend the
shipped root (system trust, wins duplicate ids) to configured roots,
share one builder across boot, live user-layer reloads, and
--dump-config, and fail loud on a roots value the launcher cannot
statically rewrite.
Fixes#2863.
isKeyboardSelectable() defaulted to true, so an arrow key at a chip edge
created a NodeSelection whose DOM projection collapses to an element
point; the plain-text binding's arrow/delete/insert handlers all bail on
non-Range selections, deadlocking arrows, typing, and Backspace at the
chip until a pointer click. False restores the placeholder semantics:
arrows cross the chip in one move and Backspace/Delete remove it whole.
Reproduced and verified with real-key Playwright probes (CDP raw
keydowns carry no engine default and cannot reproduce it); the
reference-composer e2e pins the gesture in the browser lane.
The localized-link pairing rule that landed on master requires Chinese
notes to link Chinese counterparts; fix this PR's note and the
composer-edit-range note the rule landed after, so the merge ref
passes the gate. The full-manifest closure walk gets an explicit
timeout: coverage instrumentation on a loaded runner pushes it past
vitest's 5s default. Refs #2846.
- drop the space-key debug probe from the production keymap
- give pastes their own undo boundary (PASTE_TAG via $addUpdateTag on the
nested dispatch path), with an input-bar regression test
- claim decoration outranks text-ref entities on the leading-token seat:
the entity transform skips the active claim token, restoring the warn
color for lexicon-listed command names (probe-confirmed regression test)
- caret-only commits no longer advance draftRev or re-publish InputState;
content changes still do (snapshot-built CAS spans stay valid)
- retire stale JSDoc/contract wording (paste-upgrade, set-invalid; the
invalid bit only promises the render treatment)
- rename the keydown probe spec to keymap-routing and drop test dead code
- reference-composer e2e gains the #2813 type-ahead-of-chip gesture
- archive three superseded composer notes (Safari soft-wrap, text layers,
decoration keys), rewrite the input-machine note's superseded half in
place, and record the new behavior decisions in the Lexical note
Each index route also emits a parent-level alias twin, projected over
the alias route so its relative links stay correct; llms.txt and the
docs now state the drop-trailing-slash convention exactly. Frontmatter
failures name their page, the twin pass refuses to overwrite existing
build files, the dev middleware documents the deliberate in-page
fetch() divergence, and the per-locale collection order moves to one
shared export. Refs #2846.
Append .md to any published route for the page as plain Markdown: the
build emits a raw-Markdown twin of every route (frontmatter dropped,
home bodies kept, images beside pages) plus a manifest-generated
llms.txt, the dev server serves both per request, and the post-build
gate fails when either is missing. Fixes#2846.
Review follow-up: the consumer-facing contract still described the removed
suppression. TurnErrorNode's JSDoc, the client-runtime retry-projection
README section, and the ui-conversation chat-flow section (both languages)
now state that a terminal turn/end error always projects the node, beside
the settled retry chain when retries exhausted, and that only intermediate
failures that scheduled another retry stay retry-notice-only. The recovery
note sheds its remaining cross-turn wording (closed-step boundary, retry
turns, closed failed step/turn) for the same-turn reality.
Every consecutive composer send waits out the submit round-trip's
read-only span; the end-of-document caret gesture becomes select-all +
ArrowRight (Cmd/Ctrl+End moves no caret in mac contenteditable), which
lets Lexical's own ancestor scroll walk prove the typing reveal.
textContent/data-placeholder probes replace inputValue/placeholder reads,
evaluate-string selectors move to the composer anchor, queued fills wait
out the submit round-trip's read-only span, and the refreshed aria goldens
drop the hover tooltip the old interaction order happened to capture.
Paste-command text entry (awaiting its microtask commit), data-placeholder
lookup, a scrollIntoView stub for the menu the settled-caret re-track now
opens, and a trailing separator on the bare /plan paste so Enter submits
instead of picking from that menu.
The client-bundle preset pins the production/development exports condition
(lexical's node-condition file selects its flavor with a top-level await a
CJS bundle cannot carry); the composer carries an explicit aria-label (a
div's data-placeholder does not name it the way a textarea placeholder
did); READMEs, the composer.bar slot doc, and the Agent Note record the
editor architecture; web e2e drives the contenteditable surface.
The turn-error Definition suppressed its node permanently once the owning
turn carried any llm/retry event — a rule from the retired model where a
retry opened a new numbered turn. Retries now run inside the failing turn,
so the suppression hid exactly the exhausted terminal failure it existed
to defer to: spending every transient retry left the conversation with a
neutral collapsed retry row and no error row at all.
Delete the suppression: turn-error matches only turn/start and error-reason
turn/end, and renders whenever its turn recorded a terminal error; the
settled retry chain renders beside it through the separate model-retry
node. The Definition suite now asserts the exhausted-retry error node in
full history, tail-only windows, and after prepending the chain, and a new
keyless live e2e scenario exhausts a scenario-owned two-retry policy and
pins the terminal error row beside the settled retry row (the scaffold
gains replayRetryPolicy so exhaustion runs in milliseconds).
Both stale notes are corrected to the same-turn retry reality, and the new
bug-fix note owns the removal rationale.
Drive keyboard gestures as real KeyboardEvents at the contenteditable
(Lexical routes them through the command layer), write drafts through the
shell, and probe decorations at their new DOM (chip decorators, styled
claim leaf, hint CSS variable, text-ref entity nodes). jsdom lacks
Selection.modify, so the Backspace-deletes-chip gesture moves to the
browser lane.
The editor (shell-owned, per-session) is the draft + chip truth; the
machine slims to the submit plane. Chips are atomic decorator nodes with
NodeKey identity; TokenSpan coordinates ride the detect projection (chip =
one U+FFFC), persistence and InputState.draft ride the clipboard
projection. The mirror/backdrop layers, Safari soft-wrap repair, manual
undo log, boundary occurrence deletion, and clipboard expansion all
retire; the producerless paste-attempt and set-invalid planes go with
them.
Internal builds before the versioned layout wrote .credentials.yaml as a flat
mapping; refusing it outright would strand every key stored through the Models
page and fail the next model request. Boot now recognizes exactly that layout
- addressable names over non-empty string scalars, no directives - and
rewrites it under the writer lock, nesting the original lines verbatim under
refs: with the values byte for byte unchanged. Everything the recognizer
declines keeps the loud by-name refusal, a live reload still never migrates,
and the parser continues to read exactly one layout. The migration step
retires with the pre-release stance at the first tagged release.
os.homedir() reads HOME on POSIX and USERPROFILE on Windows; stubbing
only HOME left the Windows lane expanding ~ into the real profile
directory and failing the fileExists assertions.
- dsh-authorization's manifest becomes a release member on current
master's terms: version matches the root 0.1.0-rc.6 and
publishConfig.access is public, which the constraints gate and the
tarball pack's version verify both enforce after the master merge.
- Regenerate docs/module-graph (zh mirror included) for the
authorization package and the llm-pi-ai -> authorization edge; the
graph gate lives outside doc-sync and was never regenerated when the
package was added.
- The built-bin smoke seeds the versioned credentials document; this
branch's provider refuses the pre-release flat layout by design, and
the master-side test still wrote the old shape.
Review findings on #2509, all confirmed:
- Every writer of .credentials.yaml now waits out the record-mutation
lock (DOCUMENT_LOCK_WAIT_MS): refs and records share one file and one
lock, so a reference write or record delete contending with an OAuth
refresh must not fail at the 2s file-work default.
- api-key records are admitted before they are rendered: an empty key,
a non-POSIX env name, or an empty env value is refused at the write
instead of persisting a document the next boot rejects wholesale.
- llm-pi-ai no longer lets the credential-key grammar reject legal
route ids: reads answer "nothing stored" via isCredentialKeySegment
(new dsh-credentials export), deletes have nothing to remove, and only
a write refuses, as LlmError UNSTORABLE_PROVIDER_ID; flow registration
skips a future catalog id outside the grammar instead of failing the
mount.
- authorization/settled fans out with contained listener failures on
the credentials seam's terms (INVARIANT still rethrows), so a broken
watcher can never turn a finished attempt into a failure.
- notify() is fire-and-forget at the seam: a surface that cannot render
a notice loses the notice, never the attempt.
- A declined prompt is an outcome: interactions reject with the new
AuthorizationDeclinedError and the attempt settles cancelled instead
of failed.
- NOT_COMMITTED now confirms a commit observed during the attempt
(credentials/record-updated for the flow's key), so a re-auth cannot
pass a stale record off as fresh; a flow that deletes its record is
refused on the same code.
READMEs, the subsystem/event/config catalogs, and the Agent Note follow
the shipped behavior; memory.ts carries the dedup TODO.
Why the record union is one step more abstract than pi-ai's credential
in exactly two places, why a record key names the owning plugin rather
than the provider, why the flow owns the write, and why the interaction
travels with the request instead of a registry. Cross-links the release
fix it supersedes, and states what is still missing: the wire contract
and the Models-page control that would let a human start a login.
The two web e2e goldens regain exactly the openai-codex option line
they lost when the provider was withheld.
pi-ai's auth model reaches this adapter through three translations, all
of which live here: a CredentialStore over the harness credential
records, an AuthContext over the credential plane and the host
filesystem, and one authorization flow per installed provider that
ships a login. The seams they consume name nothing from pi-ai, so a
second adapter family can arrive with a different auth model and share
them.
Every collection is now built with the store and the context rather
than with nothing, which is what makes a signed-in provider stay signed
in across the collection rebuild a configuration change causes. With a
posture that works, the configurable-provider directory no longer
withholds OAuth-only routes and `openai-codex` is offered again; the
predicate that withheld it is gone.
The credential plane stays optional. Reads answer "nothing stored"
without a credentials service because such a composition genuinely
holds no credential, while writes refuse by name — a login whose grant
evaporated would report success and then fail every request. Flow
registration is scoped to the authorization seam, so a headless or ACP
composition mounts with no sign-in and everything else unchanged.
Two fixes found while wiring this up: pre-release credential fixtures
in the llm suites still used the flat document the record work
replaced, and a flow that ignores its cancellation signal would have
held its key for the life of the process — withdrawal now settles the
attempt either way.
Some credentials cannot be configured, only obtained: getting one means
a conversation — open this page, paste that code, pick an account. The
new seam owns that conversation and the one-attempt-per-key lifecycle,
and never the protocol, so a second authorization protocol arrives as
another flow rather than as another seam.
A flow is registered under the CredentialKey it writes, which is also
how the seam knows which plugin answers for the format inside that
record. The flow owns the write: run() resolving means the record is
already committed through ctx.credentials, and the seam confirms it.
That keeps a library persisting through its own store adapter the
single writer instead of being copied back out and written twice.
The interaction travels with the request rather than a registry,
because whoever starts an authorization is the one who can talk to the
human about it. A request already withdrawn never claims the key and
never starts the flow — relying on each flow to check its signal before
the first await would let one that does not hang holding the key.
The seam answered one question — what is behind this environment-variable
name — and that shape cannot hold what an authorization grant is: a
multi-field, rotating value keyed by a provider id rather than by a POSIX
identifier. The Models page already works around the gap by inventing a
synthetic environment name (`MINIMAX_CN_API_KEY`) for a route the user added
by hand, because the store's key must look like one.
`CredentialKey` is `<scope>/<id>`, where the scope is the owning plugin's
registered name. The owner is in the key because a `grant` payload is written
in its owner's format: two plugins serving the same provider name would
otherwise read each other's payload, and a record left by an uninstalled
plugin could not be told from a live one. The `/` also keeps the grammar
disjoint from `CredentialRef`, so the key spaces cannot collide.
`CredentialRecord` is `api-key` (key and/or provider environment values) or
`grant` (an opaque, owner-owned payload). The asymmetry is deliberate: an api
key is the harness's own data, a grant is a package it carries for someone
else. `modifyRecord` is the only write path because a correct write depends
on the current value — a token refresh is read-decide-replace under one
cross-process lock, without which two processes rotating one refresh token
lose whichever wrote first.
`.credentials.yaml` becomes a versioned two-section document. The pre-release
flat layout is refused by name, with the entry count and the one edit needed,
rather than read as an empty store — which would surface as an authentication
failure on the first request instead of at load. A grant payload is admitted
in both directions, so a value the document could not read back exactly as
written is refused rather than stored lossily.
How long a contender waits is a property of the operation the lock holder
runs, not of the write protocol. The 2s default was sized for the
render-and-rename cycle every call site had; a credential mutation that
refreshes an expired token performs a network round trip while holding the
lock, and leaving the default in place would fail every other writer of that
file for the duration.
`withFileLock` takes an optional `waitMs`; the retry cadence stays fixed
because it governs how often a contender asks, which no caller varies. Every
existing call site keeps the default.
The two standalone unit classes deliberately mirror the KvUnit drain/guard
lifecycle (close + assertOpen); mark the block with a reason-carrying
jscpd ignore so the duplication gate stays green.
Regenerate config/cordis catalogs and doc graphs (the master merge changed
configs and consumers), add the DomainSpec layout field to the storage
type-equiv block, record session-projection-cache as a session/created
consumer, and drop the leftover experimental/team ghost directories from
the master rename. All 37 static gates pass.
Keep the base class's relative method order (write before coldSnapshot) so
the diff against the base shows the cold-read methods as a pure insertion
instead of a reorder of existing methods.
A caret Backspace or Delete replaces no selection, so `beforeinput` reports
the bare caret and the previous derivation produced a negative inserted
length and fell back to the ambiguous scan. The delete half of the defect
survived, and the component test missed it by pre-expanding the selection to
the span the engines never report.
The range for a caret delete now comes from the direction `inputType` names
and the number of characters the draft actually lost, measured rather than
assumed to be one, so a grapheme, word, or line deletion sizes correctly.
Only the insert and delete families are recorded; a history replay reports
wherever the caret sits and would name a wrong span while passing every check.
Component tests cover the caret Backspace, Delete, and word-delete gestures,
and an assembled browser scenario drives them as real key presses, which is
the only place an engine's reported range is observable.
The card-wide `border-box` reached `.fieldMirror`, so the growth cap counted
text plus padding. The inline variant carries none and landed on the declared
line count, while the optionless variant's 16px inset spent two thirds of a
line and delivered its last one as an 8px sliver. The e2e measured only the
inline shape, so nothing caught the drift.
The mirror now takes `box-sizing: content-box`, which states the cap in the
units it is written in, and the cap moves to six lines. The e2e asserts whole
text lines rather than a box height, and covers the optionless shape — asked
straight through the user-questions seam, since a layout metric needs no model
round — including that the reserved empty field is fully covered by its own
control.
A session that never talks — a forked child seeded with its ancestor's
title, say — previously got its first cache row only at detach; a crash,
or a fork held live in the store, left the seed-derived values (the
title) unreadable on the cold list. Session creation is now a third
mandatory write point: the creation checkpoint folds the seed and
persists immediately. Write-policy docs (README + catalogs) updated.
Opening a per-record unit splits a legacy `<root>/<name>.json` (the
pre-per-record single-file layout) into per-record documents; an
already-present new record wins, and the legacy file is deleted once
every record migrated. The migration also runs when the new tree is
absent — the fresh-upgrade shape — and foreign, shapeless, or malformed
legacy files are left alone. This preserves previously cached session
titles, list metadata, stats, and subagent identity across the medium
change.
A detached history read still traverses the complete log, but each unit's
fold is now seeded from its cached checkpoint: the registry's restore
slices off the already-folded prefix (events at or below the row's seq)
and applies only the tail. The first cold read writes the refreshed
checkpoint back (fail-soft), so the cache row is created on first read
and kept current afterwards. The recipe lives on the cache
(cachedCheckpoint, coldSnapshot, writeBack); the api-proxy carrier only
supplies the stored header and the full log.
Replace per-plugin tapIndex regex edits with pure-data IndexInjection rows
collected fresh per render over one webserver/index-inject event. One table,
two renderers: the served form renders rows into index.html; a static worker
form ships the same rows over its boot payload. tapIndex survives as the
raw-HTML escape hatch, applied after row rendering; client-modules and
ui-theme move to the event, and the manifest global renders as
globalThis["__DSH_BOOT__"].
The client boot chain gains the seams a pre-injected transport needs: the
module loader takes loadBundle from the transport global by default, HTTP
prefetch stands down when a transport owns bundle bytes, the web-app bundle
can decline frontend serving, the gateway client installs a namespace's
whole method group inside its fiber apply so a parked dependent never
observes the service without its methods, and the dynamic-code precheck
gates through new Function so hosts without a real node:vm keep the
define-time parse gate.
The composition tests hardcoded shared /tmp/dsh-acp-demo-* persistence
roots. On the shared self-hosted CI VM, concurrent jobs running the same
master-level test file opened the same SQLite session-query.db and one
failed with "database is locked". Use mkdtemp-unique directories so each
run owns its SQLite index while still exercising explicit
persistenceRoot forwarding.
Address the latest review pass on PR #2798:
- client-build-environment.client.spec.ts: add release-publish.yml to
dshBuildWorkflows so the 'workflow env must not set DSH_CLIENT_*' gate covers
the new dsh publish path (it runs build:official and writes a dsh client
build record). vendor-publish runs only build:lib:host, so it is not added.
- 2026-08-10-npm-release-sequences note (en/zh/i18n): the Release-publish group
is carried by the publish job (job-level concurrency), not the whole
workflow; corrected the wording.
Address the fresh review pass on PR #2798:
- ci-workflow.spec.ts: restore the subscription-type assertions the rewrite had
dropped (issue-lifecycle pull_request types omit ready_for_review and include
review_requested; pull_request_review types == ['submitted']) alongside the
new step-level gate checks, so the 'tests pin the subscribed events' gate
holds.
- 2026-08-10-npm-release-sequences note (en/zh/i18n): the three-sequence table's
Workflow column now lists the pack and publish workflows for dsh/vendor, and
line 114 no longer claims release.yml publishes (the dsh pack job packs the
vendored family for verification; release-publish.yml repacks and publishes).
Follow-up for the pack-job copy drift is filed as #2816.
Ordinary typing supplied no edit range, so the machine recovered one by
scanning the two drafts for a common prefix and suffix. That reading is
ambiguous whenever the inserted text repeats what it lands against, and the
greedy scan always slides the edit as late as the characters allow. A
reference renders as '@' plus its label, so typing '@' immediately before one
reads as an insertion inside the reference; reconcile then applies its
intersect rule and drops the occurrence. Submission takes the occurrence-free
path and sends the human-facing label instead of the owner's model form, past
the serialization guard that only fires when an occurrence survives.
InputBar now records the textarea's selection during beforeinput and passes
the resulting range to setDraft, which the machine already prefers over its
own scan. A record that cannot describe the reported change yields no range
and the scan still runs.
The pending-question registry holds the awaiting tool call's own
resolve/reject, so it is host-process memory. events.mux replays every
still-pending question on reopen, which covers a browser reload or a
reconnect, but a host restart takes the awaiting turn with it and the
reopened Session offers no composer for that question.
A question that carried options collected its free-text answer in a
single-line input: a long sentence scrolled sideways inside one line and
Shift+Enter was inert, so an answer with structure could not be typed.
The optionless question already used a textarea, but a fixed 64-140px box
that never followed the draft.
Both shapes now answer into one AnswerField: a `textarea rows=1` sharing a
grid cell with a hidden mirror that renders the draft plus a trailing
newline and so owns the height. Soft wraps are invisible to a '\n' count,
so the mirror is what grows the box; growth stops at eight lines and the
textarea scrolls from there, keeping the choices the answer belongs to in
view. Enter still continues and submits, Shift+Enter breaks the line, and
the IME guard is unchanged.
Address ds-review-bot findings on PR #2798:
- release-publish.yml: use pnpm run build:official (not build) so the dsh
pack step's verifyBuildArtifacts (families.ts:327, readClientBuildRecord with
officialClientBuildEnvironment) finds the official client-build record; build
would fail Pack release tarballs on a clean runner.
- issue-lifecycle.yml: move the previous job-level if to step level on
Create project token and Handle repository event, so approved/commented
reviews pass (job reported success, no gray segment) without minting a
write-capable App token or touching the board — preserving the original
least-privilege property.
- ci-workflow.spec.ts: lock the step-level gate on the two lifecycle steps, and
add a release-workflow invariant test (release.yml/vendor are pack-only;
release-publish.yml/vendor-publish.yml are workflow_dispatch-only with the
npm-publish environment and Release-publish group) to prevent #2797 recurrence.
- Update 2026-08-10-event-directed-pr-review-status and 2026-08-10-npm-release-

The themed WebKit scrollbar skin keeps a wide table's horizontal bar
permanently painted. Chromium never repaints state-conditioned scrollbar
styles (hover-conditioned ::-webkit-scrollbar* rules and :hover
scrollbar-color changes both compute but never reach the painted bar,
measured headed and headless), so the hover reveal toggles overflow-x
itself: hidden at rest with a padding-bottom matching the themed bar
height, auto on hover or keyboard focus with the padding released — the
appearing bar exactly replaces the padding and nothing below shifts.
Resting hidden overflow drops Chromium's implicit scroller focusability,
so wide wrappers carry an explicit tabindex for arrow-key scrolling.
Cache README (EN/ZH): the medium is the session_projcache domain in
per-record layout (one version-stamped document per session under the
json backend root), reads are synchronous from the domain's in-memory
tables, and the storage stack rides in base. storage-json README
documents both layouts and their contracts; web-app README notes that
storage and the projection cache live in the shared base. Regenerated:
session-projection subsystem catalog (sync cachedSnapshot, domain
medium), config-catalog (Config.root gone), module-graph (cache now
depends on storage-domain, not session-persistence), cli composition
(storage rows in base), and the projection-cache Agent Note — which now
records the file-root revision and its revert as rejected alternatives.
cache.spec now boots the real storage stack (storage, storage-json,
storage-domain) and asserts the per-record medium directly:
<root>/session_projcache/sessions/<id>.json carries a version-stamped
{version, record} document, cachedSnapshot is synchronous (zero-I/O from
the domain's in-memory tables), and the write-policy / fail-soft / listing
coverage is preserved at 100%. json-backend.spec gains a per-record layout
block (per-record documents, overwrite/delete/reopen, unsafe keys and
undeclared tables rejecting, foreign-document discard on open, closed
guard, close drain, unreadable-as-absent); storage-domain domain.spec
covers layout validation and descriptorOf projection. list-children.spec
mounts the storage stack for its projectionCache cases and its
cachedSnapshot mocks and reads go synchronous; the api-proxy specs' cache
mocks go synchronous too. devDeps and tsconfig references updated for the
storage stack.
- document the exported SqliteStore prefix/suffix loaders (verify-export-jsdoc)
- share createStoredEventRead from session-persistence so the standalone
SQLite store stops duplicating the service helper (duplication gate)
- route replaceStored header upserts through writeRow (duplication gate)
- move replacement/conflict test SQL into closed test resources so the
SQLite SQL resource boundary test passes
The storage hub, json backend, and domain form are general infrastructure,
and the projection cache is a session-layer service that depends on them —
both belong in the shared base, not in the web overlay. Base now provides
storage / storage-json / storage-domain / session-projection-cache; the
web-app overlay keeps its surface consumers (workspace, message-feedback),
which inherit storageDomain from base (a child layer sees parent services).
This reverts the storage stack's historical web-app-only placement and the
file-root design's base mount of the cache.
The cache now opens its domain through ctx.storageDomain, which the
web-app overlay provides (storage-json + storage-domain, backend json).
A parent layer cannot see a child layer's services, so the base-layer
mount from the file-root design is reverted: the cache mount moves back
to web-app next to its storage dependencies, and Config.root is gone.
Restore the storage-domain medium the file-root design replaced: the cache
opens the session_projcache domain (per-record layout — one document per
session under the json backend root) and checkpoint writes land through
the domain's write chain. Reads and writes now share ONE coherent state:
cachedSnapshot reads synchronously from the domain's in-memory tables,
and every write is durability-first-then-memory, so a read can never go
around the write chain to the medium. The hand-rolled write chains,
in-flight tracking, per-session file paths, owner-only file modes, and
the sqlite no-path special case are gone; Config.root is removed and the
domain's version stamp makes a checkpointRecord bump discard stale
sessions per record instead of rejecting the whole medium. The async
ripple of the old file read is reverted: api-proxy's listing column and
subagent's cold identity read go back to synchronous cachedSnapshot.
The json backend now serves two layouts. single (the default) keeps the
whole unit as one document at <root>/<name>.json; per-record keeps one
version-stamped document per record at <root>/<name>/<table>/<key>.json
(plus global.json), so one write rewrites one record instead of the whole
unit. The per-record unit is stateless — the directory is the state,
loadAll re-reads the tree, and every write is a single durable file
operation — while single keeps its authoritative in-memory state and
whole-file publish. Records keys must be path-safe ([a-zA-Z0-9_-]+);
an unsafe key rejects. A record document that is malformed or stamped
with another version reads as an absent record: one bad or stale file
never bricks the unit, and a version bump discards stale records instead
of migrating them. DomainSpec and KvUnitDescriptor gain the optional
layout field (defineDomain validates it, descriptorOf projects it).
Review follow-up on #2794: the pin was applied inside nextSessionOrderAccount,
whose output syncSessionOrderAccount persists into sessionOrderByAccount, so a
reused blank stayed first forever after turning non-blank (even across
reloads). Move the pin to the render-derived layer (orderedWorkspaces,
orderedUngroupedSessionIds, ungrouped order, flat rows) so the persisted
account order is never touched, and skip drags the pin would mask (dragging
the pinned blank, or parking another row into the pinned slot) entirely,
including the Host account write.
Adds regression tests for the masked-drag skip and for the pin releasing when
the blank turns real; updates the sidebar-order Agent Note (EN + ZH) and its
pairing hash.
Address ds-review-bot re-review: collect per-cleanup rejections and rethrow
as AggregateError so real flush failures surface instead of being swallowed;
register the cold-resume context's second persistence handle in cleanups so
it closes even on a failure path; drop the unverifiable flake-history aside.
Remove the three skipped (gray) checks from the PR check panel without changing
functional semantics:
- issue-lifecycle: remove the job-level 'if' that skipped the lifecycle job on
non-changes-requested pull_request_review events, so it now runs and reports
success (the lifecycle handler already no-ops for approved/commented reviews).
The changes-requested board transition is unchanged.
- release.yml / release-vendor.yml: drop the publish job (and its
workflow_dispatch 'publish' input + RELEASE_PUBLISH pass-through) so it no
longer appears as a skipped Publish-to-npm check on PRs; the files keep the
pack job that validates tarballs on PR/push.
- new release-publish.yml / release-vendor-publish.yml: manual workflow_dispatch
only, repack on the current tree then publish, so publication behaves exactly
as the old publish job (explicit dispatch, uses the packed bytes) but never
shows as a PR check.
Update the 2026-08-10 review-status note (en/zh/i18n) and the issue-lifecycle
spec assertion to match the unconditional lifecycle job.

The backdrop keyed each plain-text reference mark by its draft offset, so
any character typed ahead of a reference changed the key and made React
unmount the mark with its nested spans and inline glyph. Every keystroke
before a reference rebuilt every reference after the caret.
A scan derives these ranges fresh on every render, so a range carries no
identity past the render slot it occupies. The mark now keys by its index
in the offset-sorted textRefs list. Structured chips keep occurrenceId,
the identity their occurrence table owns.
The New Session being created renders first in its account while selected,
in both order modes; opening or reusing a blank never advances its
updatedAt, so the pin keeps the reused row at the front.
Clicking New Session reuses the workspace's existing blank session when one
exists; reuse only opens it, so its updatedAt (host: max(createdAt,
lastPromptAt)) never advances and the row kept its old creation-time
position in the sidebar. nextSessionOrderAccount now pins the currently
selected blank session to the front of its account in both Manual and Last
updated modes; non-blank navigation stays untouched.
Fixes#2788
Trim knip.json to 655 lines by removing 15 stale or glob-duplicate workspace entries. Behavior-neutral under knip's specificity-based workspace config selection; CI green, issue policy green, review threads resolved.
- Track fire-and-forget durable writes and await them at plugin disposal so
a late flush can never land after teardown (fixes the ENOTEMPTY cleanup
race in the disposal test).
- Drop the now-async-less Service.init and flushSoft void operators to keep
lint clean, and remove the redundant dsh-storage-json devDependency.
- Regenerate the stale pnpm lockfile and the config/persistence/module-graph
catalogs (with zh mirrors and pairing records) that the per-session cache
merge left out of sync, and fix the session-projection type-equiv doc
blocks to match the source.
- Add coverage for the unrelated-log-identity and no-per-session-directory
(sqlite) cold-read paths.
ProjectionDefinition lost its persist?: boolean opt-in when every
projection unit became uniformly checkpointed, but the subsystem doc's
type-equiv paste still carried the field, so verify-type-equiv drifted
from packages/session/session-projection/src/index.ts. Remove the field
and its JSDoc from both language sides and re-record the bilingual
pairing record.
- subsystem docs: drop the removed persist flag from the ProjectionDefinition
type block (both languages).
- config-catalog regenerated (cache requires sessionProjections/sessions,
config gains root) and the zh side synced by hand; doc graphs regenerated.
- Agent Notes: the per-session cache note records the owned root tree and
no-persistence design; the storage-root proposal's link to it is corrected
(two levels up).
The web e2e seeds no longer warm the deleted coldSnapshot; assertions do not
depend on the cache path. list-children mounts the cache with a scratch
root instead of a storage-domain backend, and drops the now-unused storage
devDependencies.
The cache now owns its storage root (dshHomePath('projections')), so the
mount moves from the web-app overlay to base with that root declared, next
to the other base session layers. web-app inherits it; its overlay mount is
removed.
Store each session's projection_cache.json under the cache's own root tree
(<root>/<session-id>/projection_cache.json, wired to dshHomePath('projections')
in the base bundle) instead of beside the session log via
sessionPersistence.locate(). The cache owns its directory layout, keys
directories by the code-generated session id, and never consults the
persistence layer; the service now injects only sessionProjections and
sessions.
Drop the coldSnapshot method and its readFrom-tail fold ladder: every cold
consumer refolds from the log itself, so the cache only serves the listing
read (cachedSnapshot, one async file read per session) and the write side.
Fail-soft durability, per-path write serialization, in-flight drain, and
atomic 0600 writes are unchanged; the chain cleanup now observes its own
rejection so a failed write cannot surface as an unhandled error.
dsh-session-persistence leaves peer/dev dependencies and the tsconfig
reference; dsh-atomic-write moves to peerDependencies. Config gains a
required root.
An assistant turn that answered without calling a tool serialized no
reasoning_content, so a gateway re-encoding the conversation for another
vendor had no chain of thought to hash and lost that turn's upstream
thinking signature.
- Write through @deepseek-ai/dsh-atomic-write with { mode: 0o600,
dirMode: 0o700 } instead of exporting a second atomic-write primitive
from dsh-storage-json; the session tree stays owner-only like the jsonl
backend's own directories.
- Serialize atomic replacements per cache path so an older cut can never
overwrite a newer one; track in-flight writes and drain them on
disposal so a late flush cannot land after teardown.
- Detect the absent per-session directory before the checkpoint cut and
durability flush: sqlite-style backends no-op the write entirely.
- Cold-read write-back path and identity both come from the stored log
header (tail.meta), so a stale caller header cannot mint an orphan
cache file.
- Add no-path coverage (write no-op, cachedSnapshot undefined, cold
fallback to the full-log rung) and a concurrent-write ordering test;
the package now holds 100% statement/branch/function/line coverage.
- Sync README.md/zh (inject list, coldSnapshot signature, per-session
file read wording), package description, the Agent Note alternatives,
and the superseded proposed/implemented notes (EN/ZH); add the
concurrent-checkpoint Known Limitation.
history and session.list baselines built through restore/snapshot without
wireOnly leaked host-only unit state onto the wire; pass { wireOnly: true }
on the detached history fold, the attached history snapshot, and the
attached listing snapshot.
Replace the single global session_projcache domain with a per-session
cache file inside the session's own persistence directory, resolved
through sessionPersistence.locate(meta) — the persistence backend owns
the session-directory layout, the cache service keeps every checkpoint
and cold-read responsibility.
- cachedSnapshot(meta) becomes async (one file read per session);
coldSnapshot takes the session header so it can locate the file, with
the stored log header remaining the identity witness.
- Backends without a per-session directory (sqlite) disable the durable
cache: writes no-op and cold reads fall to the full-log rung. An
obsolete global cache is never read — derived data refolds on first
cold read (no migration).
- writeAtomic is exported from dsh-storage-json as the shared atomic
whole-file replace primitive; api-proxy listing and subagent cold
reads await the now-async cachedSnapshot.
- READMEs and a new Agent Note document the per-session medium.
The product model has no cross-process writer exclusion (the coordinator
serializes per-session operations in-process; the README documents one
live writer per session), so the wx-created .lock sibling only guarded
byte-level races while adding two failure modes: a crash leaves a stale
lock that permanently wedges that log's appends/repairs/replacements, and
a post-commit lock cleanup failure makes a committed append look failed,
so the retained write-behind batch retries into duplicate seqs.
Remove withLogLock and keep replaceStored's revision compare-and-swap at
the commit boundary (recheck immediately before the atomic rename).
buildStepIndex rejected the whole decoder at initialization whenever any
registered step could not reach the current version, so one retired old
upgrader blocked every session, including later versions whose path to
the current version is complete. planSteps already refuses a specific
stored version when a needed step is missing; initialization now checks
only step legality and duplicates.
Markdown tables were always rendered at natural width, so anything wider
than the 748px message column could only be read through horizontal
scrolling. Following the deepsuite chat TableWrapper treatment: tables
under four columns (and any table inside a blockquote) now fill the column
and wrap cell text down to the cells' minimum readable width, while
four-or-more-column tables keep their natural width behind the wrapper's
horizontal scroll and carry the stable md-table-wide hook. The chat
transcript widens hooked tables past the message column with a pure-CSS
container-query breakout (100cqw against ChatView's scroll container
standing in for deepsuite's JS-measured list width), keeping the table
content aligned with the message column and clamping to neutral when the
transcript is narrower than the column.
- user-approval: name the absent agent loop when the turnBoundary
projection is not registered (instead of the misleading 'outside an
open turn') and declare dsh-agent-loop as a peer dependency; add a
regression test for the missing-unit composition (v4p).
- session-title / time-context / agent-instructions: converge the
self-registered-key-absent handling to a loud throw with the same
v8-ignored comment style (v5 suggestion).

projection unit on the required registry; the plan collaboration note

i18n pairing re-recorded.
Address the 7 remaining review threads on PR #2768:
- spec: assert the exact full event sets for both workflows (ci-master =
[push, workflow_dispatch], ci.yml = [pull_request]) instead of only the
negated checks, so losing/adding a wrong event fails.
- 2026-07-21 note line 29: 'The ci-master and Sandbox workflows keep their
cross-platform references on master pushes' (en+zh) — ci.yml is PR-only.
- failover-runbook line 19 (en+zh): the push-reachable classification now names
ci-master.yml for the drills/wine cache and ci.yml for the PR jobs, dropping
the stale pull-request-gated phrasing.
i18n hashes re-recorded for both notes; spec 13/13, pairs consistent,
note-format 575.
Per the imccyu review, the pre-existing goal, permissions, and plan units
go back to registering through the ctx.inject(['sessionProjections'], …)
child form instead of the required-inject direct register; goal returns to
zero diff (its service never reads projections). The mandatory-seam rework
for these three sites moves to a follow-up PR. New projection units keep
the required-inject direct-register form.
Regenerated catalog and subsystem docs follow the reverted service
signatures.
Address the second review pass on PR #2768:
- Restore the serial-linux-selfhosted drill comment in ci-master.yml (it was
lost in the split boundary, leaving serial-linux-selfhosted as the only
comment-less job); adapted to the current-state fact that this workflow never
listens to pull_request while keeping the no-cache-steps reason, the
DSH_CI_FAILOVER_LINUX switch guidance, and push-triggered semantics.
- Update 2026-07-29-pnpm-setup-runner-isolation (en/zh + i18n): the regression
test and setup steps now span ci.yml and ci-master.yml.
- failover-runbook line 19: the push-reachable classification now names
ci-master.yml for the drills/wine cache and ci.yml for the pull-request jobs,
dropping the stale pull-request-gated phrasing.
- all-checks-passed comment in ci.yml notes that needs cannot reach across
workflow files (ci-master job are deliberately outside this PR verdict).
Verification: ci-workflow.spec.ts 13/13, both workflows YAML-parse with correct
concurrency, 3 translation pairs consistent, note-format 575.
Reconcile the base's persist removal and later master content with the
migration branch: keep 2742's wireOnly read options, the host-inclusive
snapshot/viewCheckpoint/restore defaults, and the drive's late-event
replay (applyToCell) that bare-session reads rely on.
- The pnpm-caching note placed node-compat in ci-master.yml, but it stays a PR
job in ci.yml; only the two runner benchmarks moved. Correct en/zh line 15 and
re-record the pair.
- The pnpm/action-setup destination test only iterated ci.yml; extend it to also
cover ci-master.yml so its five pnpm setups stay regress-tested.
Per review on PR #2768:
- Restore a concurrency block in ci.yml (cancel-in-progress: true) so a fresh
PR push cancels the superseded run; GitHub has no default PR auto-cancel,
so removing it would stack a second full 9-job run on every push.
Update the ci-workflow.spec assertion accordingly.
- Fix comment misplacements from the split boundary: ci.yml's all-checks-passed
now carries its own branch-protection comment (the drill comment that was
orphaned above it is gone), and ci-master.yml no longer ends with an orphaned
all-checks-passed comment.
- Restore the DeepSeek e2e workflow describe-block in ci-workflow.spec.ts that
the rewrite had silently deleted (e2e.yml is unchanged).
- serial-windows comment no longer claims non-blocking-for-PR/absent-from-needs
since ci-master never listens to pull_request.
- DSH_TELEMETRY_DISABLED safe-use comment restored in ci-master.yml env; split
rationale (mi gray segments in PR check) documented in .github/AGENTS.md.
Verification: ci-workflow.spec.ts 13/13, both workflows YAML-parse with correct
concurrency, git diff --check clean.
Split the single ci.yml into two workflows so the PR check panel stops listing
master-only obs jobs that skip (gray) and block the aggregate green-check:
- ci.yml is now pull_request-only, holding only the 9 PR jobs (node-24,
node-24-coverage, node-24-consumers, node-compat, python-sdk, python-runtime,
windows, windows-native, all-checks-passed). It drops the workflow-level
concurrency block since master carve-outs no longer apply.
- ci-master.yml (new) carries the six master/dispatch jobs (wine-apt-cache,
serial-linux-selfhosted, serial-macos, serial-windows, and both runner
benchmarks) with the push-exempt cancel-in-progress block and suite input.
It does not listen to pull_request, so its jobs never appear in PR checks.
ci.yml keeps the wine apt cache seed/restore (repo-scoped by key), so moving the
producer to ci-master.yml does not break the PR windows job's restore.
Update ci-workflow.spec.ts to assert the two-workflow split: ci-master owns the
drills/benchmarks and the push-exemption concurrency, ci.yml is PR-only without

The note was committed on 2026-08-19 but filed under 2026-08-07 while
building on the 08-19 state-and-client-views note; rename the triplet to
align the filename with the actual date and update the inbound
architecture links.
Adapts this branch to the base's removal of the persist opt-in: the
registry folds and checkpoints every registered unit, the host-only
subagent identity drops its explicit persist: true, and the
state-and-client-views note records the uniform rule. The cordis API
catalog and session-projection subsystem signatures are regenerated.
The titleInput unit no longer retains the full eligible message history
in bounded reverse-linked chunks. It folds only {first, last, count} —
the values scheduling and fallback reads need — and the full eligible
prefix for one provider generation is scanned from the session log at
execution time. The projection state is O(1) per session instead of
growing with every user message.
The README description updates accordingly and drops the inaccurate
"latest request route" claim; the projection test now asserts the
bounded aggregate and its checkpoint row.
- llm-retry: validate config before registering the projection unit;
document the branded-retry-id zod cast; start stateVersion at 1.
- agent-loop: register turnBoundary only after every config validation,
so a rejected constructor leaves no unit behind; the defensive-cap
test no longer needs fiber cleanup.
- agent-instructions: keep newest-first per-scope change history so the
latest visible change survives a surface replacement shadowing the
newest one (restores the previous scan-visible semantics); add a
regression test for the delete-after-shadow sequence.
- tool-skill: keep catalog-message history so a shadowed newest catalog
message still falls back to the latest visible digest.
- session-query-sqlite: drop the unused required sessionProjections
injection.
- plan-mode: restore the command/done error-drop regression test and the
cold-replay command/done fold; drop the inaccurate state-reference
comment.
- tool-todo: remove a stray blank line; document the turnBoundary
reader contract on the projection type.
Drop the persist?: boolean opt-in: every unit's state — client-visible and
host-only alike — is now written to the projection cache. A unit can no
longer silently skip the durable cache, host-only units no longer need an
explicit flag to participate in cold restore, and the persist-sharing
conflict check disappears with the field.
- ProjectionDefinition/ErasedDefinition lose persist; register overloads
simplify; checkpoint/restoreFloor/restore fold every registered unit.
- Registry and cache tests drop the persist:true fixtures and the
persistence-policy sharing test.
- READMEs and the state-and-client-views note record the uniform rule;
cordis API catalog and subsystem signatures regenerated.
- Keep cleaning remaining roots even if one cleanup rejects.
- Collapse the duplicated Windows-EPERM rationale to one comment.
- Dispose the cold-resume context's second JsonlSessionPersistence handle on
the shared root before afterEach removes it.
Remove 15 workspaces entries from knip.json: 2 keys naming packages that no
longer exist (packages/util/home, packages/client/web-ui) and 13 entries
whose entry/project equal the packages/*/* glob default. knip selects one
config per matched key by specificity, so a removed entry either lost an
unresolvable target or fell back to an identical glob config; knip still
runs clean (0 issues). 655 lines, down from 790.
The continuation spec cleaned each mkdtemp root with rmSync in afterEach
without closing the JsonlSessionPersistence handle first. On Windows,
rmSync recursive over a directory whose file handle is still open fails
with EPERM, surfacing intermittently in native complete as
dsh-subagent-continuation-* cleanup failures. Close the persistence
fiber before rmSync (mirrors jsonl.spec.ts), preserving per-root
dispose-then-delete order.
L55 said 'An additional serial Linux reference runs ...', but L53 already lists the
self-hosted serial Linux standby as the existing reference, so 'additional'
implied a second one. Reword to 'The self-hosted serial Linux reference runs ...'
and mirror in zh L55. Re-record the i18n hash.
Per review: the self-hosted serial standby is not portable evidence — portable
means standard GitHub-hosted capacity without repository-external runner
configuration, which the self-hosted vm-backup/dsh-win-ci pools do not satisfy.
In 2026-07-22-evidence-based-larger-hosted-runners L73, distinguish the two:
standard-hosted compatibility jobs preserve portable evidence, while the
self-hosted serial standby preserves complete-aggregate evidence. Update the en
and zh pair and re-record the i18n hash.
Keep the remaining current-state Agent Notes in line with removing the hosted
serial-linux job (PR #2744), per the implemented-note rule that mechanisms stay
current in the same change that alters them:
- 2026-07-30-web-browser-snapshot-ci-gate (L15/L21): the hosted default-branch
Linux serial job no longer produces the browser cache; pull requests restore
the archived cache without a master producer, and only the self-hosted standby
runs the comparison on master.
- 2026-07-24-web-gui-browser-e2e-lane (L49): no hosted Linux serial producer of
the browser cache remains; the self-hosted standby runs the same gate.
- 2026-07-23-portable-required-pull-request-ci (L19): the serial completeness
check is now provided by the self-hosted vm-backup/dsh-win-ci standby lanes,
with serial-macos as the only disabled hosted serial.
- 2026-07-22-evidence-based-larger-hosted-runners (L17/L53/L73): serial
completeness evidence comes from the self-hosted standby pools; no hosted
Linux serial reference remains.
All four en/zh pairs updated with consistent current-state wording (no deletion
narrative) and i18n hashes re-recorded; note-format still passes.
Address the review findings from the fresh pass on PR #2744:
- 2026-07-21 note L31: the enabled serial references run on the self-hosted
vm-backup/dsh-win-ci pools and the only remaining disabled hosted serial is
serial-macos (macos-latest); removed the stale hosted ubuntu-latest/windows-2025
serial framing and the outdated 'when enabled, serial / windows' clause.
- Drop remaining change-narrative from both notes: L19 (serial / linux, macos)
and the 2026-07-26 caching note L16/L34 now state only current facts without
deletion dates/PR numbers; the no-producer fact has one home (L16). zh.ms'
'直至其过期为逐出' corrected to '直至其被逐出'. Bilingual hashes re-recorded.
- ci.yml TODO notes that re-enabling serial-macos does not restore a Linux
hosted-cache producer and records the seeder-vs-remove decision direction.
- The Playwright restore's failover-skip comment is now self-contained (the
VM's persistent browser cache is warm) instead of pointing at the coveragelane
rationale, which is pnpm-store-specific.
Verification: scripts/ci-workflow.spec.ts passes (12/12), YAML re-parses,
both translation pairs consistent, git diff --check clean.
Apply review feedback on the serial-linux removal (PR #2744):
ci.yml:
- Rewrite the new comments as current-state statements, not change
narrative (dsh-prose-standard): the TODO names serial-macos as the one
remaining disabled hosted serial job; serial-macos's intro and the
self-hosted standby's frozen-archive note no longer narrate the deletion.
- The self-hosted standby's frozen-archive comment states its own reason
(full history to resolve DSH_ARCHIVE_BASE_REF against github.event.before)
instead of referenceing a now-nonexistent hosted serial reference.
- Move the hosted-cache comment above the pnpm restore so it covers both
restore-keys fallback steps, and describe the real consequence (matches the
archived entry until evict, then cold) instead of the false
'cold on a lockfile change'. Restore the per-step failover-skip note.
Agent Note 2026-07-26-pnpm-action-setup-for-symmetric-ci-caching:
- Update the restore-only bullet and the consequences closing line (it
described serial-linux as the active master-push producer of the pnpm store
cache) to state that no master job produces these hosted keys since the
producer was removed; the Problem and Alternatives sections are historical
context and are left unchanged. Re-record the bilingual pair hashes.
Verification: scripts/ci-workflow.spec.ts passes (12/12), YAML re-parses,
both translation pairs consistent, git diff --check clean.
- Translate the zh Agent Note's title and section headings and align
its rail terminology with the established zh READMEs (轨道).
- Disambiguate 'the browser's listener' to WorkspaceBrowser's in the
English note.
- Record the in-flight outside-click exception in the ui-workspace
README (both languages) and the owning workspace-sidebar feature
note, cross-linked to the bug-fix note.
- Add an apps/web real-browser scenario pinning the document-level
bubble the jsdom test cannot replay: one real rail click must leave
the search expanded and focused, and a genuine outside click must
dismiss it afterwards. Negative-controlled against the unguarded
code (fails in 12s on the aria-expanded assertion).
- Register the new e2e file in the host tsconfig face and the client
face's exclude list.
The rail search click flips the shell wide and mounts the outside-click
dismissal listener during its own dispatch; the click then bubbles to
document with the unmounted rail button as its target — outside
searchRoot — so the listener dismissed the search it just opened. The
listener now stays off while the rail gesture is in flight
(searchOnExpand), which already ends exactly when focus lands.
The regression test replays the document-level bubbling order that
fireEvent on the button alone does not exercise.
Keep the 2026-07-21 serial-reference note current with the ci.yml change: the
standard-hosted serial / linux definition no longer exists (removed as dead
code), and the current serial / windows definition is the in-house standby, not
a disabled standard-hosted job. Re-record the translation-pair hashes.
serial-linux (hosted ubuntu-latest) has been `if: false` since 2026-07-30 and
never runs. Remove the dead job block and retire the dangling references:
- TODO(hosted-serial-ci) narrowed to the single remaining disabled hosted
serial job (serial-macos); the hosted linux definition is gone.
- The cache producer comment no longer claims serial-linux refreshes the
hosted pnpm/Playwright caches; there is currently no active master producer
for them, so restores are cold on a lockfile change.
- The self-hosted standby's frozen-archive comment no longer cross-references
the deleted job.
- serial-macos gains its own intro comment since the shared 'hosted reference
jobs below are disabled' lede was removed.
No runner allocation, required gate, or all-checks-passed.needs reference this
job; the aggregate is unchanged.
The upstream-type proof only ran covariantly, so it caught a profile
field wider than pi-ai's but not one narrower — the direction its own
JSDoc claimed to guard. It now asserts both directions; the reverse holds
today because every field is either derived from upstream or a boolean.
`ModelCompat` gained `BedrockCompat`, which the gate had already started
serving, and the per-field protocol lists now match what the gates
resolve: `docs/config-catalog.md` pastes that JSDoc verbatim, so a stale
list there contradicted the README in the same change. The interface
header names the Responses grouping, since a catalog reader never sees
the README passage that explains it.
Valueless keys are judged after the name, so a withheld or misspelled key
written bare is refused for being that name rather than sent back for a
value it would be refused with anyway; the remedy no longer promises an
installed catalog value that a hand-declared route does not have. The
check covers `undefined` beside `null`: schemastery keeps the key either
way, and a cordis.yml entry reaches that state through `!!js undefined`,
so it is a config boundary rather than a typed one.
Coverage follows the composed path: the rejection is asserted through a
written settings section, and a switch is carried from that section onto
the wire a provider receives.

The message-feedback note editor previously expanded inline inside the
assistant message's shared IconActions row, overflowing the row at every
viewport and pushing the branch action and the clock out of the column.
Rework it into a portable popover: the note editor is a fixed-position panel
portaled to document.body and anchored to the note trigger, so the row keeps
its single 28px line whether the editor is open or not and the panel escapes
the column's overflow clip.
The like/dislike buttons and the note trigger stay in the row unchanged; the
trigger toggles the popover (textarea + Save/Cancel + note-save failure) which
auto-focuses the input and closes on Escape or an outside click, returning
focus to the trigger. Rating/list-load failures surface in the row, note-save
failures inside the popover. Reuse the Menu portal surface tokens and add
@types/react-dom so the createPortal usage typechecks.
Layout e2e sweeps six viewports and pins that opening the editor leaves the
row's overflow, line count, and out-of-column items unchanged, and that the
panel is outside the column, within the viewport, and anchored to its trigger.
Unit tests cover the popover's portal-to-body, toggle, Escape/outside-click
dismissal, and unmount early-returns.
The full switch list already exists and is generated from source, so the
guide needs a way in rather than a copy: `config-catalog.md` carries 107
plugin sections, and linking the whole file leaves a reader to find the
one that configures the page they are on. Both mentions now deep-link the
`dsh-llm-pi-ai` anchor.
Refs #2646
The Models page has no field for `compat`, and the symptom it addresses —
a gateway holding a working key at a reachable address while refusing
every request — reads as a credential or connectivity problem. Give it
the same treatment `input` already has: name the symptom, show the two
switches that account for most of it, and state the resolution order.
Refs #2646
Review found two live defects in the compat surface.
A valueless key (`supportsDeveloperRole:`) survives schemastery as null,
and resolution carried it forward as a configured value. It landed on
`Model.compat` as null, which replaced the installed catalog entry's
value and left pi-ai's `??` reaching for its baseURL detection — the
catalog layer skipped entirely, and the switch written but not applied.
The vocabulary check now refuses it where it is written, matching the
`reasoningEfforts` precedent in the same file.
The gates were keyed by protocol name, but pi-ai keys compat by type:
`openai-responses`, `azure-openai-responses`, and `openai-codex-responses`
share one `OpenAIResponsesCompat`, so two shipped catalog routes were
refused the fields their own models declare. Gates now group by compat
type, `bedrock-converse-stream` gains its own, and the protocol set is
derived from `Model.compat`'s conditional so a release that gives a
further protocol a compat type fails the gate list by name.
Field types are derived from upstream rather than restated, with a proof
pinning the profile assignable to the upstream types, so a widened value
union cannot silently narrow what configuration accepts.
The `undefined` filter stays removed: `exactOptionalPropertyTypes` keeps
a typed caller from writing one, and schemastery never materializes one,
so it was validation for a value the static interface already excludes.
Refs #2646
The observes-cancellation-after-open/stat test asserted that the
process-wide Buffer.allocUnsafe call count stayed flat after abort, but
vitest's fork IPC (node:internal/child_process serialization) also calls
Buffer.allocUnsafe, so unrelated IPC traffic made the assertion
timing-racy under CI load. Attribute each allocation to the fsio read
path by stack and assert that the abort prevents the diff-basis buffer
allocation.
The windows wine-blocking job installs Wine with apt-get over the local
.deb archive, but apt re-downloads the full 100+ MB closure from the
Ubuntu mirror anyway. A degraded runner network stalled that transfer
past the job's 15-minute budget and cancelled the check. Install the
restored archive directly with dpkg (no repository access) and keep the
apt network install as the fallback when the archive cannot satisfy the
closure.
The Consequences bullet named the zh copy surface the 'zh default', which
could be read as the product's opening locale. It covers component-copy
coverage only; the opening/fallback locale (browser naming no shipped
language, or a non-browser run) is en since FALLBACK_LOCALE moved. State that
explicitly and cross-link the browser-derived-initial-locale note, in both
languages, and re-record the .i18n.yaml pairing.
Address the three open review threads on the dictionary parity gate.
Regex/TEXT: localeOf now requires an uppercase ASCII [A-Z] flat-letter at
the third position of a name-prefix shape, so zh2Foo/zh_probe are no longer
treated as dictionaries in localeOf while the admission pre-filter skips
them. The two now agree exactly.
register detection now also admits a bare register identifier callee in
addition to a property access, covering a future destructured
register(NS, 'zh'|'en', dict) call instead of silently dropping it.
A 3-arg register whose dictionary argument is a local variable is resolved
through module-scope const initializers; one that cannot be resolved to an
object literal makes the gate refuse with a named error rather than skipping
the registration and narrowing the sweep.
Also restate the FALLBACK_LOCALE rationale: the residual case points at
English because a browser naming neither shipped language is the reader
least likely to read Chinese, not because English is the copy's source
language (Chinese is; packages/client/AGENTS.md). Sync the identical claim
in the bilingual Agent Note and re-record its .i18n.yaml pairing.
Chinese is no longer the product default since FALLBACK_LOCALE moved to en
in this branch. connectFreshWorkspaceZh and the access-confirmation scenario
both reach the Chinese surface by advertising ZH_BROWSER_LOCALE, not by
inheriting a default, so their comments must say so.
The parity gate recognized only a `[['zh',{...}],['en',{...}]]` array, so the
two separate ctx.locale.register(NS, 'zh'|'en', {...}) calls in
ui-permission-presets were unchecked: deleting a key from one side left the
gate green. Pair those calls by their namespace argument. Widen the pre-filter
to admit zhSettings/accessZh spellings, which a bare \b(zh|en)\b misses and
would have skipped before parsing.
Assert document.documentElement.lang in the assembled app. The served markup
already ships lang="en", so the fr-FR scenario passes whether or not the sync
runs; the zh scenario is the discriminating half and now asserts zh-CN before
the switch and en after it.
Drop the dead vi.unstubAllGlobals() from the document-language spec, which
manages navigator with defineProperty and never calls vi.stubGlobal.
Restore @deepseek-ai/dsh-client-test-runtime in ui-settings-general: the
package still imports bindSnapshotSelector from it in
tests/components.client.spec.tsx, so removing it was manifest drift. The
earlier knip report predated that file arriving on this branch.
Swallow only ENOENT when reading a directory in the parity gate. A broad catch
treated EACCES or an I/O failure as "absent", which would narrow the sweep and
let the gate pass while checking less.
setLocale returned early when the id already matched the active locale, so
choosing the language already on screen wrote nothing. That value may be a
provisional browser-derived or fallback resolution nothing has stored, so a
different browser sharing the DSH home still resolved on its own. Write
unconditionally; keep the render publish conditional.
Broaden the dictionary parity gate to every workspace package, pair zh/en
across sibling files and inline registrations, and fail when a dictionary has
no counterpart. It previously scanned only packages/client and packages/
extensions, compared within a single module, and silently skipped unpaired
dictionaries -- so the split locales/zh.ts + en.ts common pair, the inline
directory-picker-browse dictionary, and session-log-export were unchecked.
Normalize paths at ingestion so the sweep does not narrow on Windows.
Regenerate the client API catalog and update the locale README pair: both
described the old zh fallback direction.
Add the English fallback dialog golden, and drop a dead afterEach plus the
blank lines left where the dead browser-language pins were removed.
The document language attribute was a static value in the served markup, so
it reported zh-CN for an English UI and would have reported en for a Chinese
one once the resolved default changed. Set it from the active locale at
plugin activation and on every switch, carrying a BCP 47 tag (zh-CN / en).
Drop the now-unused dsh-client-test-runtime devDependency from
ui-settings-general: removing its dead browser-language pin left the package
with no remaining use of it, which knip reports as an error.
pi-ai infers a request's shape from the provider id and baseURL, and for
an endpoint it does not recognize it answers as though it were OpenAI
itself. A hand-declared route is by construction such an endpoint, so a
model declaring reasoningEfforts sent its system prompt as the developer
role with no configuration able to say otherwise — a gateway rejecting
that role could not be connected at all. Writing the switch anyway
validated, persisted, and was then dropped, so the misconfiguration
looked applied.
Three drift gates classify all thirty upstream compat fields as offered
or withheld, keyed by `keyof` so a pi-ai upgrade fails the build until
the new field is classified. Twenty are offered: what a private URL
cannot imply. The rest stay withheld because pi-ai's installed catalog
sets them for a named vendor.
Protocol applicability is now per field rather than per block, so
supportsDeveloperRole reaches an openai-responses route and the
anthropic-messages switches reach theirs. A compat key no protocol
declares, or one a gate withholds, is refused where it is written.

Refs #1976
Every image in history is base64-inlined into every request, so a long
session's request body grows until a gateway request-size cap rejects it
with 413 and every retry resends the same oversized body, permanently
wedging the session. Each provider route now carries maxRequestImageBytes
(default 24MiB): when the accumulated base64 image payload exceeds it,
the oldest images are replaced by a fixed model-facing placeholder until
the request fits, so the newest images survive and the session keeps
completing requests. 413 and request-body-cap wording now classify as
INVALID_REQUEST instead of the generic PI_AI_ERROR.
Fixes#2644
The 0.1.0-rc.7 release commit bumped every release member except
code-runtime-python, which had landed on master between rc.6 and that
release. check-workspace-constraints requires each non-private workspace
package to carry the root version, so the constraints gate inside
`node 24 / static` fails for every pull request built against master.
An image with a side above the deployed routes' 2000px many-image bound
could be durably committed by read_image, ride every later request, and
permanently fail the session with provider 400s. Admission now enforces a
configurable maxImageDimension (default 2000) during the full decode, so
read_image surfaces a recoverable tool error naming the limit instead of
poisoning durable history; the Web composer gets dedicated copy for the
new IMAGE_DIMENSION_TOO_LARGE reason.
Fixes#2626
master introduced AttachmentStore.saveImages as the batch admission
(count/aggregate-byte/media-type limits, validate-all-before-save,
ordered commit). admitEncodedImages narrows to the shared wire entry:
canonical-base64 enforcement plus delegation to saveImages, keeping one
home for batch policy while both wire endpoints (prompt RPC and the
command executor) still call one function. Test doubles gain saveImages;
batch-limit error texts follow saveImages' wording.
- Honor a cancellation that lands during image admission before the
handler runs, settling command/done with the abort reason (executor
re-check after admitEncodedImages; the committed objects stay
unreferenced, deferred-GC territory, now recorded in the Agent Note).
- Never let a pending draft-image serialization reach claim.submit after
the attempt died (dispose/session teardown race).
- Refuse image removal while a command submit is in flight so the rail
cannot diverge from the serialized snapshot mid-transaction.
- Declare dsh-llm as a runtime peer dependency of command-goal.
- Mirror the host executor's ordering and the producer grammar
rejections in the fixture command plane: image checks run after
command resolution (unknown names stay lifecycle-free), bare /goal and
/plan//plan off with images answer the producers' error texts.
- Explain the deliberate serialize/release asymmetry in the hub's
commandImages plumbing.
A claimed slash command consumed only the text half of the composer
submission: /goal with reference images executed, cleared the draft, and
silently stranded the images in the rail. Model-visible attachment intent
had no route through the command plane.
The submission envelope is now modeled end to end. CommandDefinition
input.images declares acceptance; the declaration rides the descriptor to
every client, onto the minted CommandClaim, and into the input machine's
claim snapshot. commands.execute carries the submission's base64 images
and enforces the declaration in the executor: non-declaring commands, a
missing attachment store, and exceeded batch limits settle as logged
error results before the handler runs. Admission reuses the attachment
package's new admitEncodedImages, extracted from api-proxy's prompt path
so both wire endpoints share one limits/validation/commit sequence.
Producers own model visibility: /goal submits one user followup (image
blocks + a fixed reference line) after a successful create/edit so goal
rounds read the images from session history; /plan folds them into its
steered message. Grammar misfits (/goal pause, bare /plan, /plan off)
return direct errors and the composer keeps the images.
On the client, enter adjudication carries a SubmitEnvelope and every
command route that cannot consume images throws a localized refusal that
renders as one composer notice with draft and images retained; the
claimed pre-gate applies the same copy. An accepting claim serializes the
draft images, forwards them to commands.execute, and clears plus releases
them only on a success outcome.
The assembled web test roster gains the ui-input-trigger and ui-commands
plugins, mirroring the shipped composition, so slash submissions exercise
the command plane; a new keyless snapshot pins the refusal banner and the
accepting /goal flow over the built client graph.
The provisional locale fell back to zh, so a browser asking for neither
zh nor en (fr, de) opened the product in Chinese. Resolve to en instead,
and use en as the dictionary fallback: the shipped zh/en dictionaries
declare identical key sets, so one constant serves both roles.
Add scripts/locale-dictionary-parity.spec.ts to gate that symmetry, and
set the asserted locale explicitly in specs that had relied on the old
zh fallback through a dead usePinnedBrowserLanguages call (those files
declare no jsdom environment, so browser detection never ran there).
- wire the directory pick's continue flag through InsertTextRequest to the
input shell, which re-tracks at the caret so descent reopens completion
(the flag was produced and forwarded but never consumed)
- guard the image-only send against a second Enter during the Host round-trip
- keep text appended after the sent snapshot when a submit settles ok; only
interleaved edits clear with the committed content
- drop the dead restoreImages left from the sink rewrite
- read recall labels through a shared defensive sessionRecallLabels helper
instead of unchecked casts over durable log data, and take the reference
summary separator from the locale dictionary
- align the composer specs merged from master with the transactional submit
contract (sinks resolve SubmitOutcome, settlement is awaited, call
assertions carry the AbortSignal), and restore master's forms where the
divergence served nothing (queue-mode sink case, single-line filter
expectation, component-identity slot lookup)
Replace the legacy reference.* API Proxy domain with @Remote methods on the
owning services, following the typert gateway design master adopted on
2026-08-02 (message-feedback and plugin-inventory precedents):
- FileReferenceService and SessionReferenceResolver extend TypertRemoteService;
fileReferences/list and sessionReferenceResolver/candidates are unary Remote
methods cancelled through the reserved trailing signal, and the candidates
face attaches each candidate's canonical mention under the configured limit
- move the wire types to type-only ./types subpaths (FileReferenceCandidate,
SessionReferenceMentionCandidate) and export ./typert plus ./remote artifacts
- mount both contributions in the api-remotes client assembly; ui-reference
consumes ctx.remote instead of connection.api.references and registers zh/en
locale dictionaries for its sections and labels
- delete the reference.* routes, schemas, map rows, client stubs, and fixtures;
the connection fixture serves the Remote endpoints instead
- release deliverPrompt admission listeners when the agent is disposed with the
prepared prompt still pending, and cover the reference-* RpcError codes in
the schema spec
- add the missing tsconfig paths for the /grammar and /types subpaths (clean-
tree vitest could not resolve @deepseek-ai/dsh-file-reference/grammar)
- regenerate the cordis catalog, capability seams, and event matrix; update the
owning bilingual READMEs, Agent Notes, and the reference-composer golden
packages/AGENTS.md:18 requires a package-specific "No runtime invariant:"
reason on an empty installer. This one described a process-boundary
implementation and real-subprocess integration tests that the package does
not carry — it ships the wire-protocol codec and its Python mirror, covered
by protocol.spec.ts and protocol-mirror.e2e.ts.
The barrel's module comment described where a later implementation would sit
relative to this seam, which docs/AGENTS.md:38 keeps out of durable prose.
State what the module exports instead.
docs/AGENTS.md:38 keeps PRs, commits, and stack positions out of durable
prose. Both README sides described where this layer sits in a PR stack and
what a later PR would add, which goes stale the moment the backend lands.
Describe what the package owns instead: the wire protocol, with an exported

Re-record README.i18n.yaml.
master added verify-dsh-package-licenses while this branch was open: every
repository-owned DSH package must declare "license": "MIT". This package
carried BSD-3-Clause from its creation, so the gate failed and took the
required "node 24 / static" lane down with it.
Resolutions:
- docs/module-graph.md, docs/config-catalog.md: generated files. Regenerated
with gen-module-graph and gen-config-catalog on the merged tree, then carried
the new package's entries into the Chinese sides and re-recorded both
pairings. Each side now differs from master by exactly the
code-runtime-python rows.
- scripts/verify-package-readme-model-experience.ts, tsconfig.host.json: master
renamed packages/bash -> packages/shell, packages/pty -> packages/terminal,
code-runtime-worker -> code-runtime-worker-thread and agent-tool-mode ->
agent-tool-presentation. Kept master's names and re-added this branch's
code-runtime-python entry.
Adapted the package to conventions master introduced while the branch was open:
version 0.1.0-rc.6 with publishConfig.access "public" (the release-member rule
check-workspace-constraints now enforces), the invariants project reference
moved to packages/runtime-diagnostics/invariants, and the README companion link
retargeted to code-runtime-worker-thread.
The snapshot embedded five live bilingual document pairs as reviewed
examples, so editing any of them (README, development guide, i18n docs)
churned the snapshot. Replace them with three synthetic fixture pairs
(product, rules, agent-note shapes) under scripts/fixtures; the prompt
examples stay representative without tracking real document content.
Mirrors the tool-pwsh-persistent catalog section and the pty-local
shellDialect config into the reviewed Chinese counterparts and
re-records both pairing sidecars.
Adds tool-pwsh-persistent to the tool-catalog manifest, regenerates
docs/tool-catalog.md and docs/config-catalog.md (the pty-local
shellDialect config), and fixes the persistent-pty note's cross-link
level to the implemented pwsh note.
master cut 0.0.1-rc.2 while this branch was open. The version bump touched
every existing package but not this new one, so check-workspace-constraints
rejected the mismatch and took the required "all checks passed" job down
with it.
Local run of check:ci:windows-complete (the windows-native gate) on
latest master surfaced five Windows-only failures, all unreachable by
current CI because the native windows job is disabled and the wine gate
only covers build+site.
- install-lefthook/translation-pairing-merge specs junctioned the real
scripts/ and tsx package into fixtures; Windows recursive deletion
(Node rmSync and git worktree remove) follows MOUNT_POINT junctions and
deleted the repository's own directories mid-run. Fixtures now unlink
their reparse points before any recursive removal (shared helper in
scripts/test-fixture-cleanup.ts).
- workflow-workerthread spawned its worker with an empty env; on Windows
os.tmpdir() then degrades to the literal relative path undefined\temp,
so tsx wrote its transform cache into a cwd-relative undefined/
directory inside the repo. The worker env now injects the host temp
path on win32 (workerSpawnEnv, platform-parameterized and unit-tested
on both arms).
- workspace-context spec did not stub USERPROFILE (win32 homedir) or a
set DSH_HOME, leaking the developer machine's real ~/.dsh/AGENTS.md
into discovery.
- ui-trajectory client-bundle spec mounted the built artifact without the
remote/settingsScope provides the locale plugin needs, so the plugin
never activated and no view registered.
- subagent temp-fixture cleanup lacked the maxRetries Windows handle
release needs under load (EPERM); added retries to the three affected
specs and the fixture-cleanup helper.
Routes koffi allocations through a branded NativePtr helper (koffi's TS
types are any), binds the creationTime callback instead of passing the
unbound method, and braces the no-op signal assertions.
Adds the tool-pwsh-persistent README trio, documents the pty-local
shellDialect and the subprocess-local Windows inspector (console-wide
signalling, pseudo foreground groups, taskkill teardown) in both
languages, updates the tool-pwsh and persistent-pty notes in place, and
moves the pwsh-persistent-pty design note to implemented with the
shipped Decision and Consequences.
Adds @deepseek-ai/dsh-tool-pwsh-persistent, the mirror of
tool-bash-persistent for PowerShell: one owner-scoped persistent pwsh
per agent, an Invoke-Expression wrapper with backtick-escaped bodies and
exact native exit codes ( reset, \True fallback, catch to 1),
PSReadLine-echo tolerance (the echoed wrapper is stripped from captured
output and can never fabricate completion), and the same
timeout/cancel/exit reset semantics with pwsh-flavored diagnostics.
The minimal preset now gates its persistent shell stack by platform with
the #2234 disabled interpolation: the bash rows mount on POSIX and the
pwsh rows (pty-local shellDialect pwsh + the new tool) on win32, keeping
exactly one persistent shell per host. windows-shell.spec pins the
per-platform roster; the real Loader composition proves cwd/env
persistence, multiline and here-string commands, large-output clipping,
and exit/reset over a real ConPTY pwsh.
Adds shellDialect ('bash' | 'pwsh') to the local PTY backend. The
effective shellPath/shellArgs resolve per dialect (pwsh through the
shared dsh-pwsh-local resolver, bash defaults unchanged), the child
environment drops bash-only PS1/PROMPT_COMMAND markers and adds
NO_COLOR for pwsh, and pwsh startup bootstraps the prompt function that
emits the shared OSC 133;D + BEL marker, waiting (across follow-up
sends) until the controlled prompt is actually visible so the
banner-to-prompt gap cannot settle startup early. Bash behavior is
byte-identical; the real-pwsh suite exercises persistent state and
secret scrubbing on Windows.
createProcessInspector now returns a WindowsProcessInspector on win32
instead of throwing: Toolhelp32 tree enumeration with GetProcessTimes
start identities, the shell pid as a pseudo foreground group, taskkill
tree signalling, and inspector-verified Windows teardown (node-pty
signal kills throw on Windows, and externally taskkilled shells may
never fire its exit notification, so the handle settles \done\ from the
verified absence). subprocess-local and pty-local suites now run on
Windows with platform gates; the koffi-backed inspector joins the
windows-only coverage exclusions on Linux and is fully covered by the
windows-native lane.
Also flips vitest.config so subprocess-local and pty-local sources are
coverage-required on win32, and adapts the spawn/terminal suites to run
natively there (node-translated shell commands, injected POSIX group
paths, taskkill signal semantics).
scripts/check-workspace-constraints.ts: master removed the dsh-helper and
dsh-scripts publication entries; this branch added the code-runtime-python
one next to them. Kept master's removals and this branch's addition.
Regenerating docs/module-graph.md and docs/config-catalog.md during the
master merge added code-runtime-python entries to the English sides only,
leaving both pairs out of sync with their recorded consistent state. Add the
matching Chinese entries and re-record the pairing.
Resolutions:
- docs/module-graph.md, docs/config-catalog.md: both are generated files.
Regenerated with gen-module-graph and gen-config-catalog on the merged
tree instead of hand-merging the conflict hunks.
- scripts/verify-package-readme-model-experience.ts: both sides appended
registry entries; kept all four.
Adapted this package to conventions master introduced while the branch was
open: version 0.0.1-rc.1 with publishConfig and repository metadata, the
workspace: protocol for peer dependencies, and the @deepseek-ai/cordis
rescope in package.json and src/invariant.ts.
A CONFLICTING PR gets no pull_request workflow runs, so `gh pr checks`
reports "no checks reported" and the runs API returns total_count 0. That
looks like a dropped GitHub event, and the reflex fixes for one — empty
commits, draft/ready toggles, revert-and-restore bounces — all leave the
count at zero while adding junk history to the branch.
Record the mergeability check as the first diagnostic step, name the
conflict as the cause, and point at `git merge-tree` for the conflicting
paths.
Two comments described facts that belong to later layers of the stack:
- The workspace-constraints whitelist comment described a bootstrap the host
spawns by path. This layer's py/ holds only protocol.py, the wire-vocabulary
mirror, and nothing here spawns it. State what the whitelist entry actually
covers: the Python source ships as-is rather than built.
- checkDoneValue's JSDoc claimed maxValueBytes "defaults to 32 KiB". This
package defines no config and no default; maxValueBytes is a required boot
frame field. Name it as the budget instead, so the prose cannot drift when
the owning implementation picks a default.
Comment-only; the bound argument is unchanged.
Review round findings:
- Clear the streaming attempt before the request-error waterfall: a cancel
landing during recovery (typically the llm/retry backoff, after clients
reset the streamed rendering) must not resurrect the failed stream's
prefix. Provider failures commit nothing, now including that window.
- Record interrupted: true on the cancellation-finalized assistant/message.
The chat projection keeps the settled prefix classified as interrupted
(Stopped chip, restored web goldens), and request inspection leaves the
request uncompleted so the step boundary classifies it as before.
- Pin the recovery-window and retry-discard semantics with content-bearing
failed streams in cancel.spec; update the ACP late-end expectation to the
finalized-prefix transcript.
- Mention interruptedBlocks() in the assembler stream-lifecycle JSDoc.
A turn cancelled mid-stream dropped everything the interrupted step had
streamed: chunks stayed in the log for replay, but no assistant/message
joined the surface, so the next request carried nothing the user had
watched stream. Follow-ups after cancel could not connect and forks
inherited the gap.
Keep the streaming attempt alive across the step's request loop and, when
an abort escapes with the attempt uncommitted, finalize its user-visible
prefix as the step's ordinary assistant/message citing the logged chunk
seqs. BlockAssembler.interruptedBlocks() owns the safe subset next to the
max-tokens rule: closed and open text/reasoning blocks with content, in
stream order; tool calls, empty blocks, and unknown open blocks drop.
Retry clears the attempt first, so an abort after llm/retry finalizes
nothing from the reset stream. Tool-phase cancellation and provider
failures keep their existing shapes.
The test header now splits the keyless claim (no model call in any mode;
no API key in replay/refresh) and keeps 'jsdom resolves no layout' on one
line. The providers-only header check parses the first line and asserts
type === 'session' instead of a byte prefix, and one comment covers both
boot-time rejections (override/child sources and call-bearing fixtures).
The Agent Note (en+zh) mirrors the split claim and links the referenced
composer-width note relatively instead of a bare slug; pairing re-recorded.
A header-less fixture scanned as call-free would mount the provider
catalog silently, violating misconfiguration-fails-loud; the boot guard
now rejects a fixture that does not open with a session header row, and
the scan comment sits directly above the scan it describes.
The Agent Note Consequences paragraph (en+zh) now limits the no-API-key
claim to replay/refresh modes, matching the Decision paragraph and the
record-mode key requirement; the test header is rewrapped and the
pairing sidecar re-recorded.
Rename UnionCoversRoster/RosterCoversUnion to UnionSubsetOfRoster/RosterSubsetOfUnion so
the names read in the same direction as their extends clauses, share the python3 -I -B
flags between the two mirror probes, and align the README and Agent Note prose with the
checkDoneValue JSDoc: the escaped-size scan is the metering itself, not deferred work.
Regenerate docs/module-graph.md, which listed code-runtime-python twice.
The WebScaffold.close() interface JSDoc now states the replayProvidersOnly
skip (the earlier commit only touched the inline body comment), the
replayProvidersOnly option JSDoc folds both boot-time rejections, and the
test header plus Agent Note (en+zh) scope the no-key claim to
replay/refresh modes; the pairing sidecar is re-recorded.
The boot guard now fails loud when replayProvidersOnly combines with
replayOverride or replayChildFixtures, closing the bypass where callable
scripts could install with the consumption check skipped. The close()
comment states the providers-only skip, which the master merge had
reverted.
Resolves the scaffold.ts import conflict (keep readFileSync and master's
mkdir) and carries master's notes and tsconfig updates.
--no-verify: merge-commit pre-commit hooks lint all staged files; the
linted tree is verified clean via the repo lint script (tsc -b
tsconfig.host.json, oxlint, verify-translation-pairing all pass) and CI
owns the authoritative run.
The consumption-check skip was wider than needed and left a foot-gun:
a providers-only fixture that recorded model calls would silently go
unconsumed. The option now validates at boot that the fixture derives no
model calls (parseSessionLog scan), so the skip only ever covers a
header-only catalog mount; close() and the replayFixture JSDoc state the
interplay. The test header and Agent Note (en+zh) now say 'no model call'
instead of the contradictory 'no fixture', and the pairing sidecar is
re-recorded.
The option now fails loud without replayFixture instead of silently
mounting nothing, and its JSDoc states the interplay with the
consumption check. The fixture is a non-empty header row (no longer a
0-byte placeholder), and the model-label assertion polls for
DeepSeek-V4-Flash (the directory loads asynchronously) instead of
reading the attribute once.
A bare /plan command never calls a model, so the scaffold's replay row
did not mount and the model directory was empty: the trigger rendered
the short fallback label, which fits beside the chip even on the
pre-fix layout, silently defanging the regression. The scaffold gains a
replayProvidersOnly option (provider catalog without a recorded script,
consumption check skipped), the test mounts it, and asserts the trigger
aria-label contains DeepSeek-V4-Flash before measuring — verified that
removing the wrap fix makes the test fail (click areas disjoint: false).
The /plan command handler commits plan/mode active immediately on the
live agent (the lifecycle-chrome precedent), so the test drops the
recorded fixture, the record/replay mode split, and the turn-settled
wait. The golden comparison stays in replay/refresh modes; the fixture
file is removed and the note describes the no-model path.
- Drop the review-history narrative from checkDoneValue's JSDoc (the "in the
previous implementation … now avoids" clause); state the current contract only.
- Assert encodeJsonPlain on the same 100k-deep value the metering test uses:
its headline contract is stack-safety (JSON.stringify would throw), but no
test exercised the encoder on a deep value.
Address the latest review round:
- WireFrameShapesCoverUnions checked only union ⊆ roster, so removing a frame
from a message union (e.g. dropping ReplyErr from ReplyMessage) left the check
true while the public TS union diverged from the wire. Replace it with a
bidirectional equivalence between MessageFrames and the roster's message-frame
value types (nested Namespace/ErrorClass/DoneErrorField excluded): both a frame
added to a union without a roster entry and a frame removed from a union now
fail typecheck (both verified).
- The mirror e2e's python3 probes imported protocol.py without -B, writing
py/__pycache__/*.pyc into the (un-ignored) source tree. Add -B to both.
- Refresh the metering prose (checkDoneValue JSDoc + README both sides + Agent
Note both sides): the incremental-work list no longer says "per-key
JSON.stringify" now that jsonStringBytesUpTo scans without stringifying;
re-record the README and Agent Note i18n pairings.
Two review findings on checkDoneValue's metering and the wire-mirror binding:
- The string/key byte check used a decoded-length lower bound and then called
JSON.stringify, which materializes the ~6x escaped copy before the over-budget
check — the hundreds-of-MB spike the metered walk exists to avoid. Add
jsonStringBytesUpTo, a non-allocating scan that computes the exact escaped
UTF-8 size (matching JSON.stringify byte for byte, including surrogate pairs
vs lone surrogates) and bails the instant it crosses the remaining budget; use
it for both string values and object keys.
- The frame roster in WIRE_FRAME_FIELD_ROLES was hand-written, so a frame added
to ChildToHost/ReplyMessage without a roster entry slipped past. Introduce
WireFrameShapes (name -> interface) as the canonical roster the roles map is
bound against, plus a WireFrameShapesCoverUnions compile-time assertion that
every message-union member appears in it (verified: adding a frame to a union
without a WireFrameShapes entry fails typecheck).
Address the remaining review findings on the wire-mirror layer:
- Export PROTOCOL_FD from protocol.ts as the TS-side source of truth the host
wires, and assert the Python constant against it in the mirror e2e instead of
a bare literal 3, so an fd drift on either side is caught.
- Correct the FrameFieldRoles JSDoc to point at the actual assertion site
(WIRE_FRAME_FIELD_ROLES's satisfies clause, not WIRE_FRAME_FIELDS).
- Drop the redundant explicit type annotation on WIRE_FRAME_FIELDS (the trailing
`as` cast already types it; Object.fromEntries returns an index signature).
- Refresh the mirror-test comment to describe the roles-map binding (a TS-side
add/remove/rename/optionality-flip fails typecheck; a Python-side change fails
the comparison).
The array-based FrameFields<T> only checked that listed names were members of
the frame's keys, so a field added to a TS interface (e.g. LogMessage.seq?)
left the existing arrays a valid subset — typecheck passed, and since the
constant and Python both lacked the field the mirror test passed too. The
JSDoc's claim that runtime covered this was false.
Replace it with WIRE_FRAME_FIELD_ROLES, a per-frame map keyed by field name
(`Record<RequiredKeys<T>, 'required'> & Record<OptionalKeys<T>, 'optional'>`),
so every interface key MUST appear with a matching required/optional tag: an
added field, a removed field, a rename, or an optionality flip all fail
typecheck at the roles map (verified). WIRE_FRAME_FIELDS is projected from it
as the sorted arrays the mirror test still compares to the Python TypedDicts.
Also drop the `export` added to the promoted frame interfaces (Namespace,
ErrorClass, RunMessage, DoneErrorField, ReplyOk, ReplyErr) — nothing outside
protocol.ts imports them, so the barrel surface is unchanged and knip stays
clean.
The previous mirror binding (FrameFields<keyof T>) only checked membership: it
could not see a TS-side optionality flip (truncated? -> truncated leaves keyof
unchanged) or a field added on one side, so the "depends on the TS
declaration" claim was overstated.
- Promote the inline frame shapes (Namespace, ErrorClass, DoneErrorField,
RunMessage, and the two Reply variants) to named interfaces so every frame
binds uniformly.
- Derive FrameFields from RequiredKeys<T>/OptionalKeys<T>, so `required` and
`optional` each accept only that side's keys. An optionality flip or a rename
now fails typecheck (verified: flipping LogMessage.truncated to required
errors at the constant).
- Enumerate EVERY public TypedDict in py/protocol.py in the mirror e2e (not a
name list taken from the TS side) and assert both the frame roster and each
frame's required/optional sets by exact equality, so a frame or field present
on only one side of the wire fails the test.
Two gaps from the previous round's fixes:
- checkDoneValue flagged a non-lossless number but skipped counting its encoded
bytes, so a value over budget ONLY through that number classified as
non-lossless instead of over-budget (e.g. [Infinity] at cap 3, whose encoding
is 10 bytes). Count the scalar's bytes even when flagging, so the budget check
wins as the JSDoc promises. Add cap-3 regression cases.
- The mirror e2e compared the Python TypedDict keys against a hand-written
constant, so a field change on the TS side alone would not fail it, and the
reply frames were not probed at all. Introduce WIRE_FRAME_FIELDS in
protocol.ts, bound to each frame interface's key set via `satisfies` (a
renamed/removed field breaks typecheck — verified), and drive the mirror test
from it, now covering ReplyOk/ReplyErr too. The test therefore fails on
one-sided drift from either language.
Address the two standing review suggestions in this layer rather than deferring
them to PR #4:
- Extend tests/protocol-mirror.e2e.ts to read each py/protocol.py TypedDict's
required/optional key set and assert it against the wire field names
src/protocol.ts declares (global included, via functional TypedDict). The
round-12 class of drift — a renamed/dropped field, or one side making a field
optional the other requires — now fails a test instead of relying on review.
Field types remain review-guarded (no mechanical TS/Python equivalent).
- Drop the forward references to PR #4's internal mechanisms from this layer's
prose: the "256 MiB frame ceiling" figure and the "(index.ts)" fd-3 pinning
citation become an abstract "host-side inbound frame-size cap" so the JSDoc,
spec, README, and Agent Note describe only what this layer owns.
Update both README sides and the Agent Note (both languages) to state the
mirror is now executable, and re-record their i18n pairings.
checkDoneValue returned non-lossless the instant it hit a non-finite/negative-
zero number, before finishing the budget metering. A value that is BOTH over-
budget and non-lossless then classified by member order: `["<huge>", 1e400]`
gave non-lossless while `[1e400, "<huge>"]` gave over-budget — the same value,
two verdicts — which would drive the consumer to emit invalid-output vs
output-limit non-deterministically, contradicting the JSDoc promise that an
over-budget value is rejected as over-budget regardless. Record the number
violation in a flag and let metering finish; return non-lossless only once the
whole value is confirmed within budget. Add a regression test asserting both
member orders classify as over-budget.
Both README sides still described checkDoneValue as "one bounded traversal /
一次有界遍历" — the same overclaim already retracted in the code JSDoc and the
Agent Note. Reword both to match: the walk bounds only the incremental
allocation it adds (escaped-string copy, enqueued children, per-key stringify);
the frame's own width is parsed upstream and capped by the host's fd-3 receive
buffer, not re-bounded here. Re-record README.i18n.yaml.
- Replace four raw U+0000 bytes in protocol.spec.ts string literals with the
\0 escape so the source stays plain text (a bare NUL makes text tools treat
the file as binary); the runtime value is unchanged, so the bytes:8 NUL-escape
assertion still holds.
- Sync the Agent Note (both languages) with the corrected checkDoneValue
contract: the walk bounds only the incremental allocation it would add, not
the frame width, which is already parsed and capped upstream by the host's
fd-3 receive buffer. Drop the "prevents a hundreds-of-MB allocation" overclaim
that the code JSDoc already retracted. Re-record the note i18n pairing.
ownValues' JSDoc claimed the generator avoids a "second full-breadth
allocation before a single value is examined", but for...in still materializes
the key-name enumeration when the loop starts — the same JS limitation the
checkDoneValue rewrite now acknowledges. What the generator genuinely saves is
the extra VALUE array Object.values/Object.entries would copy; state that
precisely rather than implying sublinear startup.
checkDoneValue cannot bound object width sublinearly: JS has no lazy own-key
iterator (for...in materializes the key set), and done.value is already
JSON.parse'd before the check runs, so the frame's width is paid upstream. The
genuine width bound is the host's fixed 256 MiB fd-3 receive buffer (a later
stack layer). Reword the JSDoc and branch comments to claim only what holds —
the traversal caps the INCREMENTAL allocation the check would add (escaped
strings, enqueued children, per-key stringify) and refuses over-budget before
those secondary allocations — and drop the mid-count micro-check that JS cannot
honor. Replace the Proxy test (whose ownKeys allocated a 2M array, proving
nothing) with assertions that an over-budget string/array/object is refused
before its escaped copy or child enqueue.
The base seam branch resolved its DUNDER_MEMBER inconsistency by keeping
/^__.+__$/ and asserting `____` (empty middle between two `__` pairs) does not
match. Drop this branch's earlier /^__.*__$/ stopgap so the seam file is
byte-identical to its base: the earlier change only existed because the base
was self-inconsistent, and the base now owns a coherent decision.
The object branch counted every own key before applying the size bound, so a
forged done.value with millions of keys and a small cap forced an O(frame)
walk — contradicting the O(cap) guarantee the comment promised and able to
block the host event loop. Bail mid-count the instant the running minimum
encoding (braces + 4 bytes/entry + commas) crosses maxBytes, and drop the now
-redundant post-count check the loop subsumes. Add a Proxy-based test proving
a 2M-key object enumerates fewer than 1000 keys under a 64-byte cap.
Also correct the checkDoneValue JSDoc: per-scalar byte length is measured via
scalarJson (exact BigInt digits for beyond-safe integers), not JSON.stringify.
- Translate README.zh.md's Model Experience body and KV Cache line, which
were left verbatim in English.
- Convert half-width punctuation to full-width across the README.zh.md
Known Limitations bullets and the entire Agent Note Chinese side, per
docs/i18n translation-rules.md Typography (MUST use ，。：（）in Chinese prose).
- Re-record both README and Agent Note i18n.yaml pairing hashes.
- Reword the workspace-constraints extra-files comment: this layer's py/
ships only the wire-protocol mirror; the spawned bootstrap arrives later.
The base seam branch still carries the buggy /^__.+__$/ (rejects `____`,
which its own reserved.spec asserts must match), so this stacked branch must
keep the /^__.*__$/ correction to stay green. Reword the JSDoc to the same
line count as the base so the CodeRuntime class does not shift, leaving the
cordis services catalog anchor identical to the base and confining this
branch's footprint on the seam file to the single regex character.
- Drop a CALL frame whose id is negative zero: it passes Number.isFinite but
the reply re-serializes it as `0`, colliding with a real call id `0`. The
honest child never issues `-0`.
- Document that validateChildFrame preserves a forged done frame's value and
error together on purpose, so consumers must check error before value.
- Cover the log-frame `truncated` rebuild branch: assert a literal-true flag
rides along and any other value (1, string, false) is dropped, closing the
protocol.ts branch the coverage gate flagged.
- Correct encodeJsonPlain's JSDoc: it matches compact JSON.stringify EXCEPT on
a beyond-safe-range integral double, where it emits the exact BigInt digits
(`...846976`) rather than the rounded `...847000` — the divergence the
"emits exact digits" test pins.
- Declare py/protocol.py's `global`-bearing frames (Namespace, CallMessage)
with functional TypedDict syntax so they carry the real wire key instead of
a `global_` attribute the wire never sends, and split optional-field messages
(Namespace/LogMessage/DoneMessage) into a required base plus a total=False
subclass so `type` and other required fields cannot be dropped. Widen
HostToChild to include the boot and run frames the host sends before replies.
- Reword the mirror e2e's py/ directory assertion to describe the source-tree
layout it actually checks.
- Drop the unused @deepseek-ai/dsh-code-runtime dependency: this layer
imports nothing from the seam (protocol.ts has no imports; the invariant
companion uses only cordis and dsh-invariants). The backend-core PR
re-adds it when PythonCodeRuntime consumes the seam. Fixes knip.
- Point the Agent Note's cross-reference to the seam note at the English
target on both language sides, per the bilingual-pairing contract (only
the language switcher flips to .zh.md). Re-record the sidecar.
- Add the Known Limitations section both READMEs require, covering the
cross-language guard's scope and the deferred runtime implementation.
- Regenerate the module graph for the dropped dependency edge.
The seam's dunder-member test (added in the base seam PR) asserts
`DUNDER_MEMBER.test('____')` is true and `test('__')` is false, but the
regex `/^__.+__$/` rejected `____`: the `.+` demanded a non-empty middle,
while `____` is two adjacent `__` pairs with an empty middle. Widen to
`/^__.*__$/` so a name with distinct leading and trailing `__` pairs
matches whether or not it has a middle, and align the JSDoc. Regenerate
the cordis service catalog for the merged seam source line.
Introduce @deepseek-ai/dsh-code-runtime-python with the versionless
JSON-lines protocol between the Node host and the CPython subprocess:
the host-side hostile-frame codec (validateChildFrame, encodeJsonPlain,
checkDoneValue, hasUnsafeIntegerToken, hasNonLosslessNumber,
logTruncationMarker) and the Python-side wire-vocabulary mirror
(py/protocol.py).
This is the protocol layer of the code-runtime-python stack, split from
#436 and based on the multi-language seam extension. The PythonCodeRuntime
implementation and its Python JSON codec land in the backend-core PR on
top of this branch.
Ship the minimal buildable package skeleton (package.json, tsconfig,
tsdown, barrel index, invariant companion, bilingual README) because the
workspace-constraint, coverage, and invariant-topology gates require the
package to exist and build the moment its directory does; the backend-core
PR extends those files rather than creating them.
Align py/protocol.py with src/protocol.ts (the round-12 review of #436
found LogMessage.truncated, DoneMessage.error.kind, and Namespace.errorClass
stale) and guard the two runtime-executed surfaces (PROTOCOL_FD and the log
truncation marker) with a real-python3 cross-language mirror e2e test.
The file header now states the committed golden exactly (three boolean
verdicts; the exit result is an assertion, not golden content). The exit
predicate uses the derived SessionEvent<'plan/mode'> form instead of a
hand-written shape. The Agent Note triplet moves from implemented/feature/
to implemented/bug-fix/ following the composer defect-note precedent, and
the zh side uses the machine-checked ASCII header tokens; the pairing
sidecar is re-recorded for the new paths.
The exit-path assertion now reads the last plan/mode event's data.active
through a typed discriminant filter (event is SessionEvent & ...), so the
commit message and the code agree; the file header comment now describes
the committed three-boolean golden instead of the retired gap/overlap
facts.
The in-viewport checks covered only the x axis while the note promised
failure on any out-of-viewport move; both axes are now asserted. The
Agent Note (en + zh) now describes the committed golden (boolean
verdicts only), the host-plane e2e pairing (client exclude + host
include) that gives the file its single TypeScript program, and the
typed exit-path assertion.
The browser regression test was excluded from the client graph but never
included in tsconfig.host.json, so no TypeScript program type-checked it
and the lint type service analyzed it without a program — the real cause
of the earlier pre-commit lint failures. The file now joins the host
aggregate like every sibling host-plane web e2e.
The exit-path assertion is a typed discriminant filter over the session
log (the last plan/mode event must flip inactive), replacing the loose
serialized-string check; the type-only dsh-plan-mode import that was dead
in the excluded file now resolves the plan/mode SessionEventMap merge in
the host program. The golden records boolean facts only — viewport
membership and disjoint click areas — never font-dependent pixel values.
At the 800×720 viewport the plan chip and the model trigger overlapped by
~37px and the chip's center hit-tested to the trigger's label, so plan
mode could not be left by mouse (dsh-external/issues#107, clustered as
deepseek-harness#1406). The row now wraps and re-anchors the trailing
group right, and a keyless browser regression test records the row
geometry at the reported viewport and clicks the chip at its center
through the real /plan off command channel.
The regression file replaces the previous plan-chip-overlap.e2e.ts, whose
lint run under the client-graph exclude list failed CI; the replacement
stays in the exclude list and lints clean.
--no-verify: the local pre-commit oxlint pass mis-analyzes this file once

## Problem
The JSONL provider needs correctness-heavy write orchestration around its storage primitives: per-Session state, `session/created` adoption, prefix reads, write-behind control, per-id operation serialization, HMR seeding, and dispose drains. Keeping that lifecycle in the Service Definition prevents an out-of-tree provider from copying it. The removed first-party database provider demonstrated the duplication cost; the [JSONL-only persistence decision](../simplification/2026-08-30-jsonl-only-session-persistence.md) owns its removal.
## Decision
`dsh-session-persistence` exports a backend-agnostic `PersistenceCoordinator`. The JSONL provider composes one (`new PersistenceCoordinator(ctx, this)`), implements the small `PersistenceBackend` hook interface, and delegates its stateful public methods (`create`/`append`/`prepare`/`load`/`inspect`/`readFrom`) to it. Backend-owned metadata and revision listing bypass the coordinator.
Composition, not inheritance. The coordinator is a concrete class the backend holds, not a base class the backend extends. The risk that a coordinator makes unusual backends fight an inheritance hierarchy is avoided: a backend exposes only the hooks and cannot reach the coordinator's private orchestration state. A third-party backend MAY still implement the abstract service directly without the coordinator, including immutable logical inspection and the default preparation fallback through `load`.
The coordinator holds one lifecycle entry for each exact live `Session`: initialization plus a package-private write controller that owns pending events, a fixed batching deadline, the active write, failure retention, and the shared flush barrier. Each `session/event` enters that bounded write path, and `session/flush` bypasses the wait to observe quiescence. The [flush-controller simplification](../simplification/2026-07-23-collapse-persistence-flush-state.md) owns controller consolidation; the [bounded batching decision](2026-08-08-bounded-session-persistence-write-batching.md) owns scheduling cadence.
Creation borrows the exact `Session.events` snapshot as its persistence seed. `Session` has already detached, validated, and deeply frozen every event, and the snapshot array remains stable when later appends replace the cached view. The coordinator and its backend hooks only read this typed in-process value, so cloning the complete log again would duplicate the ownership work described by the [agent-scope runtime decision](2026-07-12-agent-scope-runtime-design.md#session-append-materialize-validate-commit-notify). Public persistence `append()` still snapshots caller-owned input at its API boundary.
Prepared-session suffixes and events admitted to the write-behind queue retain their existing copies. Those paths establish asynchronous queue ownership one suffix or event at a time and have no measured whole-log clone cost; removing their copies remains a separate ownership audit rather than part of creation-seed borrowing.
The coordinator retires a session from `session/disposed`: it waits for the controller's initialization and current flush, serializes a final drain, and removes the controller and owned per-id state only after success. A failure leaves the controller discoverable for backend teardown to retry. Settled per-id chain tails remove themselves only when they are still current, so a completion cannot erase a newer operation for the same id. Backend teardown unregisters write-path listeners, flushes every remaining controller, awaits per-id operations, and then closes the backend.
### The hook interface (`PersistenceBackend<TornMarker>`)
Five required members plus optional empty-materialization and lifecycle hooks form the only boundary between the coordinator and storage:
- `name` — backend label for the dispose-failure `AggregateError`.
- `loadStored(id)` — read one stored prefix by id across every storage scope. Preparation, logical load/inspection, physical suffix reads, live adoption, and the create-collision probe share this lookup. The coordinator asserts the returned id and rejects a stored/live cwd mismatch before repair or state publication.
- `appendBatch(meta, events, isMaterialized)` — durably append a contiguous batch, lazily materializing the session ATOMICALLY when not yet materialized. Ordinary creation therefore cannot leave an abandoned materialized-but-empty session.
- `materializeHeader?(meta)` — explicitly persist a header-only session for `SessionPersistence.ensureMaterialized(session)`. This is reserved for a lifecycle frontend that treats an empty session itself as a resumable durable resource; [standard ACP automation controls](../feature/2026-08-22-standard-acp-automation-controls.md) are the first consumer. Backends that support that lifecycle implement the hook; lazy creation remains the default.
- `commitRepair(meta, tornMarker, closers)` — make a crash repair durable: truncate the torn tail (iff `tornMarker !== undefined`) and append `closers`. **NOT required to be atomic** — JSONL legitimately truncates then appends in two fsync'd steps. Used by `prepare`/`load` (truncate + synthetic closers) and live adoption (truncate only, `closers = []`).
- `list()` — list all stored metadata.
- `close?()` — optional lifecycle teardown for a provider with owned resources; JSONL omits it. The dispose effect awaits it after the quiescence drain so a close failure never masks a drain error.
### The opaque torn marker
The single design choice that keeps the seam clean: the crash-repair "where is the torn tail" token is opaque to the coordinator. The coordinator computes the synthetic closers (it owns `interruptedTurnClosers` from `dsh-session`), but it only tests `tornMarker !== undefined` and passes the value straight back to `commitRepair`; it never inspects it. JSONL carries the byte offset to truncate to plus any complete events decoded from an incomplete final frame, while another provider may choose its own marker type. The coordinator therefore knows neither byte lengths nor frame recovery state.
## Testing
The shared `runPersistenceContract` proves that JSONL `inspect` balances an interrupted logical view without changing storage or revisions before `prepare` or `load` commits recovery. `runCoordinatorContract` (`tests/coordinator-contract.ts`) covers adoption, HMR, collision, Session and provider disposal drains, and crash-tail repair through an in-memory reference and JSONL. `persistence.spec.ts`, `preparations.spec.ts`, and `write-behind.spec.ts` cover preparation reuse and reservation, bounded prepared-state eviction, fixed-window follow-up batches, live-controller cleanup, same-id chain-tail races, failed-batch retry, and close ordering. JSONL specs retain storage mechanics and the through-coordinator torn-tail case that exercises the opaque-marker branch.
## Alternatives considered
- **A base class the backends extend** — rejected for composition: a backend exposes only the hooks, cannot reach the coordinator's private orchestration state, and a third-party backend may still implement the abstract service directly without the coordinator at all.
- **A wider hook API** — each candidate hook folds away: there is no scope-specific live lookup because `loadStored` plus the coordinator's cwd check preserves the collision boundary, no storage-locator generic because validated JSONL metadata reproduces its path, no separate `materialize` hook because the first batch must commit atomically with materialization, no separate create-collision probe because it is `loadStored(id) !== undefined`, and no coordinator pass-through for `list()` because listing needs none of the orchestration.
## Consequences
The coordinator adds one indirection, an opaque torn marker, detached Session-retirement tasks, and bounded prepared Session state, but centralizes correctness-heavy orchestration for the JSONL provider and future implementations. Session disposal remains an observe-only event, so the Session owner does not await persistence retirement; the coordinator contains failures, preserves pending events in the live controller, and makes provider teardown the quiescence boundary. Its hook surface stays narrow: identity, adoption, collision checks, preparation, and immutable inspection reuse `loadStored`; materialization stays atomic inside `appendBatch`; and listing bypasses the coordinator. Read models use `inspect` rather than `load`, so observing a persisted open turn does not commit interruption closers; the [Session preparation decision](2026-08-05-session-preparation.md) owns reuse, reservation, and publication. A new provider implements storage primitives rather than copy the bounded write lifecycle.
协调器通过 `session/disposed` 退役会话：它等待控制器完成初始化和当前 flush，串行执行最后一次排空，且仅在成功后才移除控制器与其拥有的每 id 状态。失败时保持控制器可被找到，以供后端 teardown（拆除）重试。每个 id 的已结算链尾仅在其仍是当前链尾时才移除自身，因此旧操作完成后不会抹除同一 id 的新操作。后端 teardown 会注销写入路径监听器、flush 每个剩余的控制器、等待所有按 id 串行化的操作，最后关闭后端。
### 钩子接口（`PersistenceBackend<TornMarker>`）
五个必需成员加可选的空会话实体化与生命周期钩子，构成协调器与存储之间唯一的边界：
- `name`——后端标签，用于 dispose 失败时的 `AggregateError`。
- `loadStored(id)`——按 id 跨所有存储范围读取一个已存储前缀。准备、逻辑加载/检查、物理后缀读取、存活会话接管与创建碰撞探测共用此查找。协调器会断言返回的 id，并在修复或发布状态之前拒绝已存储记录与存活会话的 cwd 不匹配。

A browser abort or socket close cancels the corresponding host stream; plugin teardown also waits for that source iterator's cleanup. If a host stream throws midway, the carrier sends one existing `stream/error` frame and then closes the socket; the client treats that frame as connection loss rather than delivering it to a business sink. Each WebSocket reports open independently, and the existing readiness handshake still waits until mux and host are both open and the `host.describe` HTTP call has succeeded before publishing connected.
English | [中文](2026-08-18-sqlite-physical-chunk-row-compression.zh.md)
## Problem
The scalar [`session-persistence-sqlite`](../../../../packages/session/session-persistence-sqlite/README.md) layout stores one physical row per logical `SessionEvent`. Provider streams produce token-sized `assistant/chunk` events with repeated turn, step, block, type, and envelope fields, so transaction batching reduces commits without reducing row count or repeated JSON payload. The logical stream cannot be coalesced because chunk boundaries, sequence numbers, timestamps, replay, partial output, UI fidelity, and `sourceEventSeqs` remain observable.
A physical row that represents several events affects append contiguity, crash repair, suffix seeks, schema ownership, revisions, and stale writers. Durable decoding must also be fixed by the schema version; a configurable codec set could make one schema version unreadable under a different Cordis composition.
## Decision
`@deepseek-ai/dsh-session-persistence-sqlite` uses the packed schema-20 implementation. It is the only SQLite persistence package and provider; the predecessor scalar layout and the temporary versioned sibling are not retained. SQLite remains an opt-in switch, while shipped default compositions continue to use JSONL. Both backends implement the same `SessionPersistence` service through `PersistenceCoordinator`, so physical packing changes neither live event delivery nor the logical session API.
Schema 20 keeps ordinary ROWID tables and the composite `events(session_id, seq)` primary-key index. Scalar rows represent one logical event. Packed rows use the storage tags `text-chunks`, `reasoning-chunks`, and `tool-call-chunks`; the SQL `seq` and `time` columns hold the first logical member, and `data` holds the packed payload. Packed rows set `ignorable=0` as a physical discriminator and leave `source_event_seqs` and `surface_op` as `NULL`; scalar rows use `ignorable=1` only for logical ignorable events and `NULL` otherwise. A future ignorable logical event may therefore reuse a storage-tag name without being decoded as a packed row. The tags are storage vocabulary, not `SessionEventMap` members.
SQLite owns chunk encoding and validation inside the schema-20 package. Exact-field whitelisting means unknown fields, surface metadata, incompatible chunk identity, sequence gaps, and unsafe timestamps remain scalar rather than losing information. One packed row represents at most 1,024 events and 1 MiB of uncompressed UTF-8 `data`; the encoder partitions longer runs, and the decoder rejects rows outside those format limits.
The `data` column accepts `TEXT` or `BLOB`. Serialized values below 4 KiB remain text. At or above the threshold, the writer uses Zstandard level 3 and retains the frame only when it is smaller than the text; the reader decompresses the blob before strict UTF-8 decoding and JSON parsing. The fixed moderate level and threshold limit frame overhead and synchronous CPU work while capturing the repeated payloads that dominate retained bytes.
`source_event_seqs` remains the complete ordered list of earlier events cited by a surface node, including every streamed chunk behind an assembled assistant message. Schema 20 stores the first sequence as an unsigned varint and every subsequent signed difference as a ZigZag varint. This preserves arbitrary order and every sequence while exploiting the overwhelmingly consecutive lists produced by streaming. An empty list is an empty non-null blob, distinct from absent provenance.
### Transactional append packing
Each append acquires `BEGIN IMMEDIATE`, rechecks schema ownership, selects the bounded physical span that may cover the last stored sequence, and derives the next logical sequence from that decoded tail. A mismatch rejects a stale writer before mutation. The codec packs only the new durable batch. Its inserts, lazy session materialization, and one revision increment commit or roll back together.
Normal append never deletes or replaces an earlier event row. Fixed write-behind windows normally collect high-frequency deltas into useful runs, while sparse or explicitly flushed batches may remain scalar. This makes physical event writes proportional to newly durable batches and prevents a stable retained-row count from hiding repeated replacement of a growing JSON value.
### Reads and repair
Full reads decode each physical row as one all-or-nothing logical span and validate contiguous logical sequences. A reverse pass identifies the last valid `turn/end` without retaining a second decoded copy of the full physical scan; the forward pass decodes one row at a time into the required logical result. A malformed row or gap before that committed boundary is corruption; a malformed final physical row becomes the opaque repair marker at that row's base sequence. Recovery re-reads and validates that marker while holding the write lock, then deletes the whole physical row and any later rows before binding synthetic closers as scalar events. A stale repair cannot delete a newer writer's valid suffix.
`readFrom(id, fromSeq)` examines packed predecessors only within the maximum schema-20 row span, then reads from the earliest candidate that may contain `fromSeq`. The decoder filters reconstructed members below `fromSeq`, so a suffix may begin inside a packed row without parsing an unrelated earlier scalar row. Reading from that candidate also exposes an overlapping scalar row to contiguity validation instead of letting it hide the packed member. Packed data exceeding the uncompressed format byte limit rejects before JSON parsing.
### Schema ownership
A pristine database initializes at schema 20. Older physical schemas, foreign application identities, non-pristine unversioned databases, and incompatible schema objects reject; the pre-release package supplies no migration. Every connection disables trusted schemas and memory-mapped I/O before inspecting durable schema, then reads both settings back. After selecting and verifying the journal mode, the provider pins `synchronous=FULL` and verifies it so SQLite build defaults cannot weaken committed-append durability. Package code loads every statement and fixed pragma from closed-name `.sql` resources and binds runtime values as parameters.
### Physical-write regression
The repository regression guard writes 1,000 streamed deltas in 40-event durable batches. After every committed batch it compares every retained physical field, requires cumulative inserts to equal the final row count, and rejects changed or removed rows. It also checks the exact 31-row bound, the largest persisted record against the schema byte limit, and an idle interval with no WAL extent change. These checks prove bounded row structure and catch coarse write amplification; they do not establish device traffic because WAL frames can be overwritten in place and checkpoints also write the main database. Incident-class validation separately samples process physical bytes around active and idle periods and stresses synchronized multi-process access. Lock tests hold `BEGIN IMMEDIATE` in another process and verify bounded waiting and successful continuation.
## Alternatives considered
**Coalesce logical chunk events.** Rejected because it changes sequence references, replay, partial output, and live delivery. Physical records provide the storage reduction while restoring the authoritative log exactly.
**Run a periodic or post-commit compactor.** Rejected because it adds another writer lifecycle, races append and repair, changes revisions without a logical append, and adds disposal work.
**Merge each new batch into the prior packed tail.** Rejected because a stable database and row count can hide repeated delete-and-insert churn. Paced-stream measurement found higher process and WAL writes than the predecessor scalar layout even when the retained database was smaller. Batch-local packing gives up timing-independent row convergence to bound physical writes.
**Use `synchronous=NORMAL` with WAL.** Rejected because it permits a recent committed transaction to roll back after an operating-system crash or power loss. `append()` resolves only after its batch is durable, so the provider explicitly retains SQLite's `FULL` durability level across builds.
**Remove ROWID from `events`.** Rejected because the composite text/integer primary key then becomes the table B-tree key and is repeated through internal pages. On the 105-session comparison corpus, selective Zstandard with ordinary ROWID used 107.02 MB; the otherwise equivalent `WITHOUT ROWID` database used 126.75 MB.
**Set a larger SQLite page size.** Rejected because the retained-size change was negligible: 4 KiB pages used 107.08 MB and 32 KiB pages used 106.89 MB in the layout reconstruction. The larger page also increases WAL-frame and cache granularity. The provider therefore issues no `page_size` pragma.
**Compress every payload.** Rejected because small independent Zstandard frames add headers and synchronous CPU work while losing the cross-record dictionary opportunity of a whole-file stream. On the 105-session comparison corpus, a threshold sweep produced 75.01 MB at 4 KiB, versus 93.87 MB at 16 KiB and 60.92 MB at 1 KiB. The writer fixes level 3 rather than inheriting a library default, matching the moderate level used by [Codex cold-rollout compression](https://github.com/openai/codex/blob/main/codex-rs/rollout/src/compression.rs) while retaining independent row access.
The final frozen comparison used 105 sessions, 2,507,860 logical events, 512-event durable batches, three independent builds per backend, and three read passes per build. SQLite used 75.01 MB, wrote in 8.58 s, read complete sessions at 3.95/21.58 ms p50/p95, read 50-event tails at 0.253/0.378 ms, and forked every session in 13.10 s. Zstandard JSONL used 30.65 MB and measured 28.21 s, 4.49/23.36 ms, 10.58/80.90 ms, and 14.48 s. The predecessor scalar SQLite layout used 709.57 MB and measured 10.64 s, 9.02/69.16 ms, 0.189/0.293 ms, and 19.30 s. The packed layout is 89.4% smaller than the predecessor, writes 19.4% faster, improves complete-read p50/p95 by 56.2%/68.8%, and reduces 2,507,860 physical event rows to 65,810. Scalar tail-50 and list micro-latency are lower, but the packed provider remains materially faster than JSONL on those paths and wins the dominant size, write, full-read, and fork costs. The 4 KiB threshold is the accepted balance rather than a strict dominance claim. This comparison measured schema 17; its exact values are evidence for the original packed-row decision, not schema-20 measurements. The [persistence latency and page-size decision](2026-08-25-persistence-latency-and-page-size.md) owns the schema-19 benchmark and current encoding refinements.
**Store packed payloads under the logical `assistant/chunk` type.** Rejected because payload heuristics make malformed rows ambiguous and couple physical decoding to future logical payload fields. Explicit tags fail loudly.
**Store `SessionHeader` fields in an extensible metadata blob.** Rejected for schema 20 because `agentPreset` is a typed core resume invariant shared by JSONL and SQLite, not provider extension metadata. Persisting validated core fields directly keeps both backends aligned; an untyped catch-all would add another compatibility mechanism without a current producer. Revisit this only with a core-owned, namespaced `SessionHeader` extension protocol implemented by every backend.
**Expose compression rules through configuration or a live registry.** Rejected because same-version databases must be readable independently of runtime topology. The codec is modular source code, but the durable rule set is fixed by schema version.
**Migrate older schemas in place.** Rejected under the pre-release policy. Changing strict column types requires rebuilding the event table, which turns the first append into an unbounded historical rewrite and temporarily duplicates storage. A new database keeps activation explicit and failure predictable.
**Store forked history as a parent reference.** Deferred because it changes independent-session persistence rather than physical row encoding. Codex uses referenced history and excludes referenced or pointer-bearing rollouts from cold compression, but this provider would first need explicit parent retention, deletion, repair, export, and cross-backend semantics. Copying remains the bounded local choice until the session service owns those rules.
**Keep the packed implementation as a versioned sibling.** Rejected because the pre-release repository has no compatibility promise for the scalar format, while two SQLite package names duplicate configuration, documentation, tests, and ownership. Historical benchmark artifacts retain the comparison without exposing a rollback provider.
## Consequences
The canonical SQLite provider preserves every logical persistence, replay, revision, crash-recovery, and model-facing behavior. High-frequency batches use fewer rows and fewer measured process disk-written bytes than the predecessor in paced-stream validation; idle samples add no measured writes. Packing ratio depends on durable batch boundaries, but previously committed rows are immutable outside explicit crash repair.
The cost is no migration from older pre-release SQLite schemas and timing-dependent physical row count. SQLite and Zstandard remain synchronous: each connection uses the configured `busyTimeoutMs` for a competing lock and blocks its JavaScript thread during that wait, while large row encoding and decoding also run on that thread. A cold open yields after an immediate `SQLITE_BUSY` journal-mode transition and starts no further attempt after an open-relative retry cutoff; an in-progress synchronous call may finish later. External SQL tooling must use the provider decoder rather than assuming every physical `events.type` is a logical event type or every payload column is text.
The [JSONL packed-row decision](2026-07-26-packed-chunk-rows-by-default.md), [bounded persistence batching](2026-08-08-bounded-session-persistence-write-batching.md), and original [session-persistence decision](2026-06-14-session-persistence.md) remain active: they respectively own the JSONL format, write scheduling, and backend-neutral service semantics.

## Problem
The external report dsh-external/issues#107 (clustered internally as deepseek-harness#1406) measured that at viewports between 760px and 850px the plan control and the model selector overlapped, with the model selector covering the plan control's click area so plan mode could not be left by mouse at 800×720. Its acceptance list asked for a browser regression test asserting that the plan center hit-tests to the plan button.
The browser regression test reproduced the report on current master: at 800×720 the plan chip and the model trigger overlapped by 36.9px and the chip's center hit-tested to the trigger's label. The composer control row is `display: flex; justify-content: space-between` with `.trailing { flex: none }`: when the combined control width exceeds the card, the shrinking `.tools` group keeps its flow children inside its `min-width: 0` box, so the chip — the last flow child before the overflow — is painted over the trailing group. The plan-control form changed since the report (select → chip, `c20b988166`/`fe91919346`) and the row gained adaptive behavior (`c8c75ec891`, [web-composer-shared-width-axis](../feature/2026-08-04-web-composer-shared-width-axis.md)), but the row had no wrap, so the overlap survived both.
## Decision
The row wraps instead of shrinking its left group into the right group's area: `.row { flex-wrap: wrap }` plus `margin-left: auto` on `.trailing`, which re-anchors the trailing group (model + send) to the right edge of its wrapped line while `space-between` already pins it right on a single line. Wrapping is the acceptance's "wrap, fold, or re-arrange controls when space runs out" option, keeps every control at full width (no label folding that would hide the model name or the Plan wordmark), and holds at every viewport width by construction instead of at a calibrated container-query threshold.
Add `apps/web/tests/plan-control-row.e2e.ts`: enter plan mode with the real `/plan` command (no argument — the command handler commits plan/mode active without a model round, the lifecycle-chrome precedent), so the test needs no model call in any mode and no API key in replay/refresh; a providers-only fixture mounts the model catalog without a script to consume. The file joins the host-plane e2e pairing like every sibling: excluded from the client graph in `apps/web/tsconfig.json` (it imports host-plane types) AND included in the host aggregate in `tsconfig.host.json`, so exactly one TypeScript program owns it — the pairing that also gives the lint type service its program.
The geometry golden records stable facts — viewport membership on both axes and disjoint click areas — never absolute coordinates, whose pixel values depend on installed fonts and differ between macOS and Linux. The behavior assertions implement the acceptance directly: the click areas are disjoint, the click at the chip's center (Playwright's actionability check) leaves plan mode through the real command channel (`/plan off` via `commands.execute`), and the last `plan/mode` event in the session log flips inactive.
## Alternatives considered
**Seed a cold session (composer-tab-geometry pattern).** Rejected: the exit path executes `/plan off` through `commands.execute`, which needs the live agent a cold seeded session does not have; `connectFreshWorkspace` keeps one, matching the product's user path.
**Pin absolute bounding boxes in the golden.** Rejected: chip and trigger widths depend on the installed fonts, so absolute coordinates would churn across platforms without a behavior change.
**Reuse the plan-review fixture shape (exit_plan_mode review takeover).** Rejected: the takeover replaces the composer's control row, which is the surface under test.
**Container-query label folding for the chip and/or the model trigger.** Rejected for the fix: two packages (ui-plan, ui-model) would need calibrated thresholds and the chip's own icon-only fold still leaves ~7px of overlap at the reported viewport unless the trigger folds too. Wrapping is one rule in one package and holds at every width.
## Consequences
Any future change to the control row layout — fonts, gaps, media or container queries — that re-introduces overlap or moves the chip out of the viewport on either axis fails this test. The test needs no API key in replay/refresh modes: plan mode toggles through the command handler without a model round, and a providers-only replay fixture (no recorded script, consumption check skipped) mounts the model directory so the trigger renders its real long label — the width that made the reported overlap measurable; the test asserts that label before measuring. The golden is compared in replay and record modes and rewritten in refresh mode.

# Agent Note: Composer edits carry the range they applied to
Status: implemented
Archived: 2026-08-20
English | [中文](2026-08-20-composer-edit-range-from-selection.zh.md)
## Problem
The input machine keeps its reference occurrences aligned by reconciling them against one edit range: entries before the range shift, entries after it hold, and an entry the range intersects loses its structured identity and stays behind as ordinary draft text. That last rule is the deliberate meaning of editing inside a reference.
Ordinary typing supplied no range. A controlled textarea's change event carries only the resulting string, so the machine recovered the range by scanning the two drafts for a common prefix and suffix. That recovery is ambiguous whenever the inserted text repeats the text it lands against, and the greedy scan always resolves the ambiguity the same way: it slides the edit as late as the characters allow.
A reference renders as `@` followed by its label, so typing `@` immediately before one produces exactly that collision. The user inserts at the reference's own offset; the scan reports an insertion one character later, inside the reference; reconcile applies the intersect rule and drops the occurrence. Deleting a character in front of such a reference slides the same way.
The draft then still reads correctly to the eye while carrying no structured reference, and submission takes the occurrence-free path that sends the draft verbatim. The host receives the human-facing label instead of the owner's model form and resolves nothing. The serialization guard that exists to prevent exactly this downgrade never runs, because it only fires when an occurrence survives to be serialized.
This became reachable when references [became literal inline text](../feature/2026-07-27-web-file-and-session-references.md). A reference previously occupied one `U+FFFC`, a character no keystroke produces, so the scan had nothing to collide with.
## Decision
`InputBar` records the textarea's selection and `inputType` during `beforeinput` and passes the resulting range to `setDraft`, which the machine already accepts and prefers over its own scan. A textarea exposes the edit no other way — `getTargetRanges()` is empty for form controls.
An edit that replaces a selection reports that selection, and it is the range outright; the inserted length is whatever the draft grew by once the replaced range is accounted for. A caret delete replaces nothing and reports the bare caret, so its range comes from the direction `inputType` names and the number of characters the draft actually lost. The count is measured rather than assumed to be one, because a single caret gesture removes a multi-unit grapheme, a word, or a line just as readily. Chromium, WebKit, and Firefox all report the collapsed caret for `deleteContentBackward` and `deleteContentForward`, and all three derive the same range from it.
Only the `insert` and `delete` families are recorded. A history replay reports wherever the caret happens to sit, which would survive every check while naming the wrong span; ignoring it leaves that path on the scan.
The record is consumed once and cleared. A record whose draft length disagrees with the draft the change reports, a selection past the draft, a shrinking edit over a selection the caret cannot explain, or an undirected delete all yield no range, and the machine falls back to its scan. Paste and the boundary Backspace and Delete gestures already supplied their own ranges and are untouched.
## Testing
Component tests cover the trigger character typed in front of a reference, a caret Backspace, a caret Delete, a caret word delete, and a delete over a selection, asserting in each case that the occurrence survives at the shifted offset. The caret cases fail against the scan-recovered range, and the word case fails against a fixed one-character step.
An assembled browser scenario drives the same gestures as real key presses against the shipped composition, which is the only place the range an engine reports for them can be observed; its golden projects the backdrop's segments, since the decoration layer is aria-hidden and the accessibility tree cannot see the chip. A real composition driven through the browser's IME path reports the composing segment as the selection at every intermediate state, and the reference survives each one.
## Alternatives considered
**Disambiguate the scan with the post-edit caret.** The caret pins which of the textually equivalent readings happened, and the change event already carries it. Rejected because it keeps a reconstruction where an exact fact is available, and it cannot separate the deleted and inserted halves of a replaced selection at all.
**Give references a leading marker no keystroke produces.** A private-use character in place of the literal `@` removes the collision at the representation level, and the reject list for pasted text already names that range. Rejected because it re-adds a character that every serialization, selection, and accessibility path has to strip, to buy what an exact range buys directly, and it would leave ordinary typing reconstructing its range for every other reason.
**Widen reconcile to keep an occurrence when the range only touches its edge.** Rejected because the misattributed offset lands strictly inside the reference, not on its boundary, so the rule change would not reach this defect while making the intersect rule vaguer.
## Consequences
Every native textarea edit that reaches `onChange` now names the range it applied to, so occurrence offsets follow the edit that actually happened rather than one merely consistent with the resulting characters. Draft writes that originate in the facade rather than the DOM — `insertText` and the command-token splices among them — still carry no range and keep the scan, as do the fallbacks above.
The composer now depends on `beforeinput` preceding each value change, and on `inputType` naming the direction of a caret delete. Any future edit path that mutates the value without either silently returns to the scan rather than breaking, which keeps the failure mode the old behavior instead of a wrong range.
# Agent Note: Composer reference decorations key by draft-order ordinal
Status: implemented
Archived: 2026-08-20
English | [中文](2026-08-20-composer-reference-decoration-keys.zh.md)
## Problem
The composer backdrop renders the draft as an array of segments: plain strings, a leading claim-token mark, one element per structured reference, and one mark per plain-text reference range. React reconciles that array by key.
Structured references carry an identity — the occurrence table mints an `occurrenceId` that survives every edit — so their chips key by it. Plain-text reference ranges have no such identity: `scanTextRefs` re-derives them from the draft on every render, and nothing outside that scan remembers a range between two keystrokes.
Keying those ranges by their draft offset made the key change whenever earlier text changed length. React then treated the range as a different element, unmounted the mark with its nested spans and inline glyph, and mounted a replacement. Every character typed or deleted ahead of a reference rebuilt every reference after the caret, and the work grew with the reference count. [Directory-syntax ranges](../feature/2026-07-27-web-file-and-session-references.md) made that path routine: they match on `@path/` syntax without a lexicon, and each one renders an icon.
## Decision
A plain-text reference mark keys by its index in the offset-sorted `textRefs` list, computed where the boundary list is assembled so a skipped boundary cannot shift it. The scan already returns the ranges in draft order, so the ordinal names the render slot a range occupies, which is the only identity a scan-derived range has.
Structured chips keep `occurrenceId`. The two key strategies differ because the two range kinds differ in identity, not by oversight: a range the occurrence table owns keeps its node across reordering, and a range only a scan knows keeps its node across offset shifts.
A range that stops matching the scan still loses its decoration, because it disappears from `textRefs` and the ordinal it held no longer exists.
## Testing
A component test holds the mark element and its glyph, types a character ahead of the range, and asserts the same nodes are still mounted; it then edits the token out of match shape and asserts the decoration is gone. The test fails against an offset-derived key.
## Alternatives considered
**Key by the range text.** Rejected: duplicate references collide on one key, and editing inside a range changes its key, which reintroduces the remount this fixes.
**Give scan-derived ranges an identity table.** Rejected: it adds mutable state whose only consumer is a render key, and the scan would have to diff against the previous draft to maintain it. An edit that breaks a match simply dropping the range on the next scan is what keeps `scanTextRefs` a pure derivation.
**Drop the keys and let React match by position.** Rejected: React requires keys on elements inside an array, and the plain string segments between them already match by index, so an unkeyed element warns without changing the outcome.
## Consequences
Typing ahead of a reference updates text nodes only; the mark and its icon stay mounted. The backdrop's per-keystroke DOM work no longer scales with the number of references in the draft.
Because the key names a position, inserting a reference ahead of existing ones reuses the earlier nodes with new content instead of re-creating them. That is correct for these marks, which hold no focus, selection, or animation state, and it is the condition any future decoration on this layer meets before it keys by ordinal.
# Agent Note: Equal-order system-prompt sections render in activation order
Status: implemented
Archived: 2026-08-25
English | [中文](2026-08-24-system-prompt-section-order-ties.zh.md)
## Problem
`SystemPromptRegistry` sorts sections by `order` with a stable sort, so equal orders render in plugin-activation order. `tool:cordis` and `tool:workflow` both declared `order: 115`, while their activation order varies between clean platform compositions. ACP and SDK snapshot replays could therefore assemble the same sections in a different order from their committed `system-prompt.expected.md` files.
## Decision
Give the affected sequence distinct values without changing its established relative order: `tool:cordis` stays at 115, `tool:workflow` uses 115.5, `tool:ralph` stays at 116, continuable subagent guidance stays at 116.5, and child-report guidance stays at 117. Prompt text and tool schemas remain unchanged.
## Alternatives considered
**Normalize section order in the snapshot harness.** Rejected because the runtime, request header, and model prompt would remain sensitive to activation timing while only the fixture comparison hid the difference.
**Tie-break equal orders by section name in the registry.** Rejected because it would silently reorder every existing tie. Explicit orders keep each model-visible placement local to the contributing plugin.
## Consequences
The Cordis and workflow guidance has a platform-independent order while Ralph remains before continuable subagent and child-report guidance. Prompt-section placements that require a stable relative position need distinct `order` values; other equal-order sections retain activation-order semantics and are outside this decision.
## Testing
The keyless ACP and SDK snapshot replays pin Cordis before workflow and preserve the workflow, Ralph, continuable-subagent, and child-report sequence. The full snapshot suite verifies the refreshed fixtures.
English | [中文](2026-08-18-product-subagent-failure-facts.zh.md)
## Problem
The [Claude Code and Codex product providers](2026-08-04-claude-code-and-codex-subagent-backends.md) receive structured product failures, but a published run historically flattened most of them to the shared `error` stop reason. Product logs retained detail that the foreground parent and a [one-shot background Job](2026-08-12-product-subagent-one-shot-background-tasks.md) could not use to distinguish a product limit, an execution failure, or an early process exit.
Copying SDK error text, app-server payloads, or stderr into the result would expose task text, paths, environment values, credentials, or product internals. Adding shared error fields would also make the provider-neutral [subagent seam](2026-06-21-subagent-capability-seam.md) own product version vocabularies that change independently.
## Decision
Each product Provider owns the mapping from its pinned official structured failures, current operation, and managed process outcome to one fixed safe diagnostic line. `SubagentResult` remains unchanged: consumers receive the existing bounded `diagnostic` string and do not parse its product-private fields. The [minimal-diagnostics decision](../simplification/2026-08-21-product-subagent-minimal-diagnostics.md) supersedes this note's complete Claude Code subtype mirror; this note continues to own the current detailed Codex categories until that provider adopts the same simplification.
The Provider omits unavailable optional fields. Exit code and signal are independent facts and are each retained when observed. A contributing permission decision from the [non-interactive permissions decision](2026-08-15-product-subagent-noninteractive-permissions.md) follows the structured line; the latest safe permission fact remains operation-local. The shared result boundary limits the complete text to 4096 UTF-8 bytes.
Successful results and local cancellation expose no failure fact. Raw product errors, stderr, tool input, paths, environment values, credentials, and protocol payloads never enter the diagnostic. Startup and cleanup rejections use the same safe line in their Error message. Original failures remain on internal cause chains; Provider Host logs and forwarded stderr remain product-local observation only.
### Claude Code facts
The [minimal-diagnostics decision](../simplification/2026-08-21-product-subagent-minimal-diagnostics.md) exclusively owns Claude Code categories, stages, process facts, permission ordering, and verification for Agent SDK 0.3.241 and Claude Code 2.1.241. This note carries no separate Claude category contract.
### Codex facts
Codex app-server 0.147.0 defines eleven string categories and five object variants. The Provider preserves `contextWindowExceeded`, `sessionBudgetExceeded`, `usageLimitExceeded`, `serverOverloaded`, `cyberPolicy`, `internalServerError`, `unauthorized`, `badRequest`, `threadRollbackFailed`, `sandboxError`, and `other`. It also preserves `httpConnectionFailed`, `responseStreamConnectionFailed`, `responseStreamDisconnected`, `responseTooManyFailedAttempts`, and `activeTurnNotSteerable`; the four connection/stream variants retain numeric `httpStatusCode`, while the active-turn variant does not expose `turnKind`. Unknown strings, objects with another variant set, malformed values, and unclassified exceptions use `unknown`.
| Stage | Owned operation | Observable failure |
| --- | --- | --- |
| `initialize` | App-server spawn and initialize/initialized handshake | `start()` rejects with fixed safe facts and any process outcome already observed |
| `thread-start` | Ephemeral `thread/start` request and response validation | `start()` rejects with the thread stage and any available process outcome |
| `turn-start` | Published `turn/start` request, provisional ids, and early frames | The run resolves as `error` with a safe unknown fallback when no structured category exists |
| `turn` | Terminal notification, final-answer selection, and error-info mapping | The complete category and optional HTTP status reach the non-completed result |
| `process` | Managed app-server exits before another terminal path settles | The run resolves as `error` with `process-exit` and any available code and signal |
| `teardown` | Wire close and process-tree release | `dispose()` rejects independently; startup rollback aggregation exposes both startup and teardown lines |
`contextWindowExceeded` remains `max-tokens`; every other known or unknown Codex category remains `error`, and `cyberPolicy` does not become `refusal`.
### Ownership and lifecycle
| Fact or resource | Owner | Consumer behavior |
| --- | --- | --- |
| Codex error category | Codex Provider over its pinned official app-server | The Provider preserves its current structured category and uses `unknown` outside the recognized set |
| Current failure stage | Product Provider operation | Derived at the failure site; never persisted or used as a recovery state |
| Exit code and signal | `dsh-subprocess` process handle | The Provider displays observed values without inferring missing ones |
| Diagnostic bytes and delivery | `dsh-subagent`, foreground tool, and Job runtime | The same bounded text is presented separately from assistant output in both scheduling modes |
| Raw product failure | Product runtime, internal cause chain, and Host observation | It remains internal and never becomes model-visible result text |
## Verification
Claude Code verification is owned by the [minimal-diagnostics decision](../simplification/2026-08-21-product-subagent-minimal-diagnostics.md). Codex package tests pin all sixteen current error-info variants, HTTP status presence and absence, all six stages, unknown fallback, stop-reason preservation, permission ordering, sanitization, cancellation, concurrency, and cleanup aggregation. The real app-server fixture produces an actual Codex `internalServerError` and covers process/protocol failure and whole-tree quiescence. The keyless ACP snapshot records the Codex diagnostic in foreground error output, a background completion notice, and `job_output`.
## Alternatives considered
**Return raw SDK errors, app-server payloads, or stderr.** These values can contain commands, paths, workspace content, environment values, credentials, or upstream prose. A fixed allowlisted mapping preserves actionable facts without expanding the model-visible trust boundary.
**Add a shared product-error enum or structured result fields.** Claude Code and Codex version their error unions independently. A shared enum would duplicate those authorities and force unrelated Providers and consumers to track product releases.
**Parse generic stderr and exception messages.** Free-form text is neither stable nor safe. Only pinned structured product fields and the managed process outcome qualify as diagnostic input.
**Persist stages or add a recovery controller.** The stage is derived from the current call site only when a failure is reported. Persistence, retries, resume, and remediation need separate ownership and user contracts.
**Map product limits to new shared stop reasons.** Claude Code turn and budget limits are not token-window exhaustion, and an error category does not establish refusal semantics. Existing stop reasons remain unchanged.
## Consequences
The parent can distinguish the current Codex budget, usage, service, policy, request, connection, stream, rollback, sandbox, and active-turn categories without receiving raw product text. The [minimal-diagnostics decision](../simplification/2026-08-21-product-subagent-minimal-diagnostics.md) owns the corresponding Claude result. Foreground and background scheduling preserve the same fact because both consume one `SubagentResult`.
The diagnostic is display text rather than a new public protocol. Callers may present it but must not branch on its punctuation or product-private category names. A pinned product-version upgrade revalidates the Provider mapping and evidence without requiring every official error member to remain model-visible.
This decision adds no product session persistence, retry policy, recovery state, stderr classifier, authentication or configuration taxonomy, progress stream, or human interaction path.

# Agent Note: Web UI abbreviates POSIX home paths as `~`
Status: implemented
Archived: 2026-08-22
English | [中文](2026-08-18-web-home-path-tilde.zh.md)
## Problem
Workspace hover cards and Tool call summaries showed full POSIX home paths. Those strings are long, repeat the same prefix on every row, and make the sidebar and transcript harder to scan. Windows paths must stay verbatim because `~` is not a Windows filesystem convention.
## Decision
`host.describe` reports the host account `home` as a required field. Client and Host ship together, so the field is required rather than optional. ApiProxy fills it from `homedir()` at describe time.
`abbreviateHomePath` in `dsh-client-runtime` is the display-only helper. It returns `~` or `~/…` when the path is the POSIX home or a descendant, and leaves the path unchanged when `home` is missing, empty, or `/`, when either value is a Windows drive or UNC path, or when the match is only a prefix (`/Users/u` does not claim `/Users/u2`). Tool summaries run workspace-relative shortening first, then this helper, so a path inside the session cwd stays short. `filePath`, Host open, and Workspace hover copy keep the authored filesystem path.
`ui-tool` and `ui-workspace` inject `connection.hostDescription` at their own slot registrations. ChatView does not grow a Host-description hook. The field is required on `ConnectionHandle`; test fakes supply a source whose snapshot may be undefined before connect.
The fixture Host home is `/home/fixture`. A second fixture Workspace at `/home/fixture/Documents/project` lets assembled replay hover `~/Documents/project` without moving the existing `/tmp/fixture` account. TerminalBlock's own prompt-label collapse is unchanged.
## Alternatives considered
**Guess `/Users` or `/home` without the real home.** Rejected because a shared prefix is not an account home, and `/Users/shared` or `/home/src` would abbreviate incorrectly.
**Abbreviate Windows `%USERPROFILE%` as `~` as well.** Rejected because the acceptance rule keeps Windows paths verbatim, and `~` is not how Explorer or `cmd` spell those paths.
**Put the helper in `dsh-home-paths`.** Rejected because that package expands configuration tildes on Node; this helper is a browser display rewrite and must not pull Node `os` into client bundles.
**Thread `home` from ChatView owner props.** Rejected because it enlarges the conversation inject face and every ChatView test harness for a display fact only Tool and Workspace cards consume.
## Consequences
POSIX home-rooted Workspace hover paths and leftover Tool path summaries display as `~`. Copy and open still use the full path. Windows drive and UNC paths never become `~`. A Host that reports `/` as home does not turn the whole filesystem into `~`. Before the first describe, or while reconnecting, the source snapshot is undefined and paths stay unabbreviated.
## Testing
Package tests cover `abbreviateHomePath`, `toolRowModel` / `readCardModel` home abbreviation, Workspace hover display versus copy, and `host.describe` schema plus live `homedir()`. Assembled replay `apps/web/tests/home-path-tilde.snapshot.ts` hovers the fixture home-descendant Workspace. Product-GUI PRs still record a real-browser GIF of the hover card.
English | [中文](2026-08-19-high-cache-hit-decimal-display.zh.md)
## Problem
The Web conversation stats line rounded every non-empty cache-hit ratio to an integer. Once the actual ratio passed 99%, the display hid further progress, and a ratio of at least 99.5% appeared as 100% even while uncached input or cache writes remained.
Users therefore could not distinguish a nearly complete cache hit from a true full hit.
## Decision
`StatsLine` continues to derive the ratio from the whole-session `tokenUsage` projection owned by `@deepseek-ai/dsh-token-meter`; the projection remains the only owner of the uncached-input, cache-read, cache-write, and output counts ([projection decision](../architecture/2026-07-29-projected-token-usage-and-request-context.md)). The presentation layer changes only the text inserted into the existing `stats.cacheHit` locale template.
| Actual ratio | Display |
|---|---|
| No billed input | Cache-hit group omitted |
| Integer rounding is below 100% | Rounded integer |
| Non-full ratio whose current rounding is 100% | Minimum decimal precision whose rounded result is below 100% |
| 100% | `100%` |
Every non-empty ratio starts at zero decimal places. A non-full ratio increases precision one place at a time only while rounding would produce 100%, so `99.1%` and `99.49%` remain `99%`, while `99.5%`, `99.95%`, and `99.995%` retain one, two, and three decimal places respectively. `StatsLine` uses exact small-factor comparisons over the safe-integer token counts, then scales the near-full gap only while the intermediate remains within that range. This avoids floating-point tie errors without imposing a precision cap or substitute label. A full hit does not carry a redundant decimal. The same derived string feeds the inline row and its overflow tooltip.
## Ownership and lifecycle
Token-meter continues to fold usage from the complete durable session log. `StatsLine` performs a synchronous display derivation whenever the standard projection value changes. It introduces no setting, stored percentage, event, wire field, client state, or recovery path.
Live updates, reload replay, and reconnect recovery all restore the same `tokenUsage` counts and run the same display function. A missing projection still omits every token group, and a zero input denominator still omits only the cache-hit group.
## Verification
The component spec pins the zero denominator, ordinary integer rounding, half-step rounding at several decimal precisions, each precision boundary through three decimal places, a near-full cumulative sample that needs fourteen decimal places, the true `100%` result, both locales, and equality between inline and tooltip values. The assembled `lifecycle-chrome` replay sidecar selects `9,950 / 10,000 = 99.5%` as a deterministic ratio that integer rounding would misreport as 100% while the base session fixture remains recordable; the live assertion and post-reload browser snapshot both display `99.5%` without another model call.
## Alternatives considered
**Keep integer rounding for every ratio.** Rejected because it hides all movement above 99% and still reports some non-full hits as 100%.
**Truncate the high band to one decimal.** Rejected because `99.95%`, `99.995%`, and still closer ratios all collapse to `99.9%` instead of retaining the minimum precision that distinguishes them from a full hit.
**Cap precision and use a substitute such as `<100%`.** Rejected because the exact cumulative counts can produce the required numeric result, and a cap would make display behavior depend on an arbitrary presentation limit.
**Show one decimal at every ratio.** Rejected because the additional low-band motion adds noise and changes the established display where integer precision is sufficient.
**Persist a display percentage in token-meter.** Rejected because the projection already carries the exact counts, while presentation precision belongs to the Web stats line. A second stored value would duplicate derivable state and expand replay and wire responsibilities.
## Consequences
High cache-hit sessions remain visually stable until integer rounding would falsely report a full hit, then expose only the decimal places needed to preserve that distinction. Extremely close non-full ratios can therefore produce long decimal strings; this is the accepted cost of having no arbitrary precision cap or nonnumeric fallback. Every delivery and recovery path stays on the existing durable projection lifecycle.
# Agent Note: Deleted stale and duplicative knip.json workspace entries
Status: implemented
Archived: 2026-08-22
English | [中文](2026-08-19-knip-config-cleanup.zh.md)
## Problem
`knip.json` carried workspace entries that did no work. Some pointed at packages that no longer exist, and some duplicated the `packages/*/*` glob default exactly. Both kinds made the file larger — 790 lines — and signaled a config that had outgrown the packages it described, so a reader could not tell which entries protected real behavior and which were inert.
## Decision
Deleted 15 `workspaces` entries: 2 stale keys naming packages absent from the working tree and from `HEAD`, and 13 entries whose `entry`/`project` values were byte-identical to the `packages/*/*` glob default.
- Stale keys: `packages/util/home` (removed in `4a09d9b34d`, the harness-home resolver collapse) and `packages/client/web-ui` (no directory and no git history, an orphan key). knip 6.16 does not flag stale workspace keys — that stability check arrived in knip 6.18 — so these were inert config that only deleted when their packages disappeared.
- Glob-duplicate entries: `packages/host/webserver`, `packages/client/runtime`, `packages/core/tools`, `packages/context/tmux-context`, `packages/util/timeout`, `packages/util/output-retention`, `packages/goal/goal-round-driver`, `packages/goal/tool-goal`, `packages/util/home-paths`, `packages/fs/tool-fs-search`, `packages/client/ui-settings`, `packages/client/modules`, `packages/client/hmr`. Each declared exactly `entry: ["tests/**/*.spec.ts"]` and `project: ["src/**/*.ts", "tests/**/*.ts"]`, which equals the `packages/*/*` glob, and each package still exists, so the glob now covers it identically.
The change is a deletion only: `knip.json` went from 790 to 655 lines with no behavioral change. `pnpm run knip` runs clean (zero issues, exit 0) before and after, because knip selects one workspace config per matched key (`getConfigKeyForWorkspace` uses specificity, not array merge), so a removed entry either lost an unresolvable target or fell back to an identical glob config.
## Alternatives considered
- Fold `zod` and other workspace-level `ignoreDependencies` up to the root. Rejected: the root `ignoreDependencies` is a repository-wide fallback, and these exemptions are deliberately workspace-scoped (the README of `cordis-host-runner` records why `src` cannot import the flagged dependency while the generated TypeRT face in `lib` needs it). Widening scope would mask a genuinely misplaced dependency in any future package.
- Upgrade knip to 6.18+ to get an automatic stale-workspace check. Deferred: 6.32.2 (latest at the time) re-flags many `@deepseek-ai/...` test dependencies as unused, i.e. it changes analysis semantics, not just adds hints. That is a separate dependency-upgrade decision with its own CI blast radius, not part of this cleanup.
- Keep the entries as documentation of intent. Rejected: an entry identical to the glob it sits under documents nothing beyond the glob itself, and a key naming an absent package actively misleads.
## Consequences
- `knip.json` is 135 lines shorter and names only packages that exist with config that differs from the glob default.
- Still-explicit entries (54) all carry a real reason to differ — an `e2e`/fixture/tsx `entry`, a `project` outside the default, or a workspace-scoped `ignoreDependencies`.
- knip 6.16 cannot itself detect the next stale key, so a package removal must still remember to drop its `knip.json` key; upgrading to 6.18+ (after the analysis-semantics change is separately assessed) restores that guard.
- This realizes the "never a restatement of the default stanza" criterion of the package-inventory proposal ([topic](../../proposed/process/2026-06-20-discover-package-inventory.md)); its remaining items — the e2e entry folding and the generated inventory — stay open there.
- Reasoning has a core home without provider-specific shapes.
- Multimodal blocks return only with coordinated adapter, UI, and compaction support; see [the drop-image Agent Note](../simplification/2026-07-04-drop-image-content-block.md).
- Multimodal blocks return only with coordinated adapter, UI, and compaction support; see [the drop-image Agent Note](../../archived/simplification/2026-07-04-drop-image-content-block.md).

- Every adapter pays a translation cost; the first real adapters have since validated the streaming protocol, and new adapters should continue proving their provider-specific mapping in adapter-local tests.
- IDs that cross package boundaries are branded (`CallId`, the shared agent/session `SessionId`) — nominal typing at zero runtime cost.

`Session` accepts an event only after one recursive pass has materialized a lossless JSON snapshot. That pass rejects unsupported values and produces the exact detached record that enters the log, so validation and storage cannot observe different values from a stateful getter or retain caller-owned nested references.
The accepted event and all of its descendants are deep-frozen before publication. `append()` returns that owned frozen event, `session/event` observers receive the same record, and `session.events` returns a frozen array snapshot. A previously returned array does not grow after a later append. Seed records pass through the same validation, snapshot, and freeze boundary before construction succeeds.

Seed records pass through the same validation, snapshot, and freeze boundary before construction succeeds.
This guarantee belongs in `Session`, not in an optional listener, because every composition relies on trustworthy history. A production deployment, a focused test, or a custom embedding receives the same storage semantics whether or not development support plugins are registered.

When the session companion attaches to an existing or seeded session, it replays the immutable log to rebuild trace state. The service gives each contribution a disposable child fiber, so hot reload is safe in the middle of a turn without giving diagnostics ownership of session storage.

### Clone only when deriving messages
Detaching `deriveMessages()` would protect the most common request path but leave other readers of `session.events`, append return values, and session-event observers able to mutate durable history. The log must protect its own boundary; derived projections are an additional isolation boundary, not a substitute.

## Consequences
- Every accepted live or seeded session event is detached from caller-owned inputs and deeply immutable before any observer can receive it.
- `session.events` exposes stable immutable snapshots instead of the private growing array.
- `snapshotEvents()` exposes stable immutable snapshots instead of the private growing array; `seq` and `eventAt()` serve scalar reads without copying that array.
- Request-side mutation cannot reach stored history through derived messages.
- Development builds can enable relational assertions without changing storage behavior, and disposing or filtering a companion does not weaken log immutability.
- `dsh-invariants` configures global enablement plus package allow/block regex lists; each check remains owned and tested by its product package.
