- `catalogHistory` validated its durable read. `agent.session.events` is a
JSONL/SQLite seed on resume or fork, and seed validation guarantees only a
source object with a non-empty `kind`; a `skill-catalog` record with missing
or wrongly shaped `entries` threw inside the step listener, failing every
later turn of that session. It is now skipped as an unrecognizable record,
the posture the replaced content digest had, with a regression test over six
malformed shapes.
- The headless keyless smoke still filtered catalogs by the old plugin source,
so the `built-bin-smoke` gate would not have found the catalog message.
- Entries record the published description unescaped. The pseudo-XML escaping
belongs to the `<available_skills>` frame and is applied when rendering it,
so a description containing `<` no longer reaches the card as `<`.
`escapeText` is injective, so republish semantics and the model-facing text
are unchanged.
- Adjacent text blocks join with no separator, matching how provider adapters
flatten them; the body no longer shows a line break the model never saw.
- Provenance fields are bounded like the text: an unknown producer may record
an arbitrarily large value.
- Both readers are all-or-nothing, and the row's form marker reports what
rendered rather than what was declared, so a partly unreadable record cannot
present a confident but incomplete account.
- The catalog body consumes `update` as a replacement notice; the digest
canonicalizes per entry as JSON, since every separator character is itself
legal in a description.
- `core.md` documents the form axis with a `ContextForm` type-equiv block, and
both projections assert the wiring they duplicate.
Injected context reached the transcript as one anonymous shape whose
expanded body was the whole message serialized as inline JSON, so the
escaping collapsed the only readable part — the model-facing prose —
into a single line.
`MessageSource` gains an optional producer-declared `form`, a small
semantic vocabulary of information shapes independent of `kind`: kind
says who produced the context, form says what shape it is, so several
producers may share one presentation. Two values ship.
`instructions` (workspace-context) lists the reconciled files above
their text and keeps the `<system-reminder>` framing verbatim, because
the framing is part of what the model read. `catalog` moves dsh-tool-skill
off the shared plugin kind onto a `skill-catalog` source carrying the
published name/description entries, and the body lists those instead of
re-parsing `<available_skills>` out of the prose. Catalog identity moves
with it: the republish digest now covers the durable entries, deleting
the text-slicing that recovered them from a logged message.
Everything else renders the opaque body — the model-facing text with its
real line breaks, then the remaining provenance as fields. That is the
documented default, not a leftover: a resumed, forked, or foreign log
must render whether or not its producer is mounted here, which is why
the classification lives in the durable source rather than a client-side
table keyed by producer.
The goal scenario asserted a paused revision-2 goal, but the pause is
appended only after cancellation reaches idle — after turn/end. Under
parallel snapshot files the subprocess could dispose before the pause
record persisted, folding the log to an active revision-1 goal.
Add a waitForEventAfterTurnEnd input step (the turn-end/title waiters'
shape, parameterized by event type) and use it in the goal scenario to
hold the subprocess open until the goal-state record lands.
The seam gains ShellDialect ('bash' | 'powershell' - concrete shells, not
families: zsh or fish would be their own values, never 'bash'); bash-local
declares bash (bash-sandbox inherits), pwsh-local declares powershell, and
both tools throw at load when the mounted executor speaks another dialect -
previously tool-pwsh over bash-local handed PowerShell text to bash -c and
the deployment error surfaced as ordinary nonzero exits. Pinned by mismatch
tests on both tools; the parity note records the contract (both languages).
Also from the review round: the tool-bash README's managed-environment
section becomes a summary linking the owning dsh-bash-env contract (the
duplicated prose carried a stale owner in its example import), the
pwshOnly JSDoc drops the stale 'on PATH' phrasing, and the task-tools
contract comment in the two pwsh compositions is indented into its block.
The injected instruction persists as a durable user message, so an
unscoped 'Do not call any more tools.' stays in every later request's
history. Scope it: '...in this run; further work waits for the user's
next instruction.' A/B probes on deepseek-v4-pro show the scoped wording
is non-inferior in-turn (4/4 zero tool calls, closing quality unchanged)
and next-turn tool use is unaffected under both wordings; the scoped
form states the instruction's actual lifetime.
- scrubbedParentEnv folds case before the DSH_ prefix check (Windows env
names are case-insensitive; a parent dsh_* entry read back as \*
in the child) and the service spec pins the lowercase probe.
- The acp.snapshot.ts pwsh probe follows resolvePwshPath() like the package
suites, so a Windows host with only an install-location pwsh still runs
the scenario.
- pwsh-tool-turn is re-recorded around [Console]::Out.Write('PWSH_OK'):
the fixture carries no platform newline, so one recording replays on
Windows and POSIX alike (record + refresh; replay-verified keyless).
- The pwsh-local Known Limitations bullet drops the self-defeating no-op
advice: & { } is scoped to param(...), using/#requires scripts run from a
file (both languages, pairing re-recorded).
- The capability-seams graph moves ctx.bashEnv ownership to bash-env and
lists pwsh-local/tool-pwsh on the ctx.bash seam (source updated,
docs regenerated).
- The tool-bash presenter fixture retires the stale 'command aborted'
literal for the shipped 'tool call aborted' message.
The hand-edit in 348ab41151 put the seq-17 abort error inside the tool-result
message and dropped a closing brace, breaking every JSONL consumer; tool-calls.ts
appends 'error' as a data-level sibling of 'message' (the seq-19 shape), so the
fixture now matches the emitter.
Coverage: pwsh-local's executor suites self-skip without a real pwsh, which left
per-file 100% unreachable on pwsh-less contributor hosts (mirror of the existing
windowsCoverageExclusions contract). A PATH-only probe exempts only
pwsh-local/src/index.ts; CI runners ship pwsh and still enforce the full bar.
docs/testing.md (+zh, pairing re-recorded) names the prerequisite; the testing.md
budget rises 1120->1150 because the coverage-gate contract genuinely grew.
A goal round reporting complete or blocked used to conclude the turn at
the tool result, so the model never spoke after the call and sessions
ended on a bare update_goal card. The terminal update now defers one
plugin-sourced <goal_complete>/<goal_blocked> instruction onto its
result asking for a grounded closing message without further tool
calls; the turn then ends through the ordinary no-tool-calls stop.
Direct-human mutations stay uninstructed. Wording chosen by A/B
sampling on deepseek-v4-pro; one extra request per goal lifecycle.
New keyless ACP snapshot goal-wrapup drives the shipped app through
create -> round one -> autonomous complete and pins the injection, the
same-turn closing message, and the completed turn end.
- listChildren() takes an optional AbortSignal and rechecks it after every
un-signalled session-query await (the cold-resume cooperative-cancellation
boundary); list_agents forwards exec.signal so the registry's drain of
started tool bodies cannot block on a slow or large catalog.
- The list_agents description now presents running/complete as a stored-record
snapshot and defers deliverability to send_message, matching the ownership-
conflict semantics the service tests pin.
