additionalProperties: false on the todo_write item schema is model-visible
(tool schemas ride the request header and the code-mode prompt types), so
the pinned ACP/headless expected outputs re-record. Keyless refresh; the
two locally-failing scenarios are this machine's known environment issues
(HOME-symlink cwd normalization, SQLite ExperimentalWarning), not the diff.
master gave 2026-06-29-todo-write-tool a Chinese counterpart; the English
side's web-consumer sentences now translate across (in-body links keep
their .md targets per the pairing contract) and the pair is re-recorded.
The todo-panel fake gains the time/callTime fields ToolResultNode now
requires.
The projection sentence prescribed resetting todos on window rebuild —
the implementation deliberately preserves the tail-page seed and lets
only in-window/live writes overwrite. The toolview section named a
nonexistent ctx.toolviews registry — the shipped seam is the keyed
conversation.chat.toolview slot via ctx.slots.register. Both sides of
the bilingual pair re-recorded.
additionalProperties stays true in the published schema while execute
rejected extra keys, so generated typings and validation disagreed with
runtime behavior. The item schema now declares additionalProperties:
false — the registry's arg validation rejects extra keys with a
path-qualified violation before execute runs — and the redundant manual
check is dropped (tool catalog regenerated).
repairGap installed the repulled window without the response projection;
a todo/write missed during the gap and already outside the new tail page
kept the stale list. The spec pins adoption through the repair path.
sessionHistoryValueSchema declared only events/hasMore, so the fetch
carrier's Zod parse stripped the tail page's todos projection — the
in-process and fixture paths carried it while a real WebApiClient lost it.
The fetch-carrier spec pins the field through the wire round trip.
The client's todos projection derived only from the paged display window,
so reopening a session whose last todo/write preceded the tail page showed
an empty plan until the user paged back — session-level state cannot be
reconstructed from an arbitrary window. The host owns the full log, so the
tail history response now attaches todos (latest todo/write backscan, the
same posture as the view pairing); installWindow seeds it, window rebuilds
preserve it, and any in-window or live write keeps overwriting it. The
fixture mirrors the host; docs and both Agent Notes record the mechanism.
runtime README documents ConversationSnapshot.todos and its window-scoped
limitation; the todo tool README and Agent Note name the web client among
the event consumers; the web display note records the cold-load gap and
fix directions (bilingual pair re-recorded).
Eight real bundles through the DI chain in ?fixture mode: plan strip
content, dedicated row summary + details linkage, collapse hint, zero page
errors — the CI-gated assembled-surface coverage for the todo display.
The tool appends the snapshot mid-execution, between tool/call and
tool/result; the fixture spliced it after step/end with a post-turn
timestamp, so acceptance never exercised the production ordering. A spec
pins call → snapshot → result with monotonic times.
null roots, non-object roots, and null array items (retained verbatim on a
rejected tool/call) now take the documented generic-summary fallback instead
of throwing into the row error boundary.
An item carrying keys beyond content/status (ids, children, priority) was
flattened to {content, status} on append, so the logged snapshot diverged
from what the model believed it wrote (model-visible must equal logged).
Reject loudly; the isError result lets the model self-correct.
fx-alpha gains turn 63: a todo_write call/result pair plus the todo/write
snapshot event, feeding both the TodoRow toolview and the TodoPanel strip
in ?fixture mode. verify-todo-display.mjs drives chromium through panel
visibility, content, row summary, details linkage, collapse and dark.
TodoPanel pins above the composer (776px card axis), hidden while empty,
collapsible with the active item as the collapsed hint; status glyphs
mirror the TUI plan panel. todo_write rows render a plan-flavored summary
(counts + active item) via the toolview registry, generic fallback on
malformed args. Existing fake snapshots gain the required todos field.
Session consumes the todo/write session event as a per-event side effect
(last write wins), rebuilds it on window replay/paging/resync, and exposes
snapshot.todos. TodoItem re-exported through the runtime surface.
The fake terminal retains earlier autocomplete frames, so the directory follow-up assertion could pass before the scoped lookup completed. Wait for the quoted file mention to be applied before submitting.
