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`.
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.

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.
