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.
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.
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.
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.
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.
