Tianyi Cui 3633cf90c8 fix(review): contain provider-removed listener failures; pin the model-via-request path
ds-review-bot round 2, both warnings:

- subagent/provider-removed now routes through emitLifecycle (per-listener
  containment, the subagent/start|end precedent) instead of raw ctx.emit,
  whose dispatch halts on the first throw: a throwing subscriber can no
  longer starve a later mirror into keeping a stale tool, nor disrupt the
  backend fiber's teardown mid-disposer. provider-added deliberately keeps
  propagation (register-time rollback semantics, like the system-prompt
  registries); the asymmetry is documented on emitLifecycle, the event
  JSDoc, and the provider-lifecycle RFC.

- The documented model-via-agent/request fallback composes with a
  {{model}} persona via the ownership rule itself: the plugin supplying
  the model late states it early on the system-prompt/assemble waterfall.
  Declined re-ordering render after agent/request — it would break the
  agent/pre-step contract (compaction must measure the prompt the model
  sees). New loop test pins the supply path end-to-end; the RFC's
  {{model}} consequence bullet now covers supply as well as switch.

Tianyi Cui 3f83a4ee96 review: the persona becomes the system-prompt plugin's deployment config
Review round 2 (tianyicui inline comments):

- dsh-system-prompt itself registers the harness:identity (-100) and
  deployment:persona (0) sections — they must survive a swapped loop
  plugin, so they leave dsh-agent-loop; the persona text is the plugin's
  own validated 'persona' config. The model/cwd variables STAY on the
  loop: runtime facts of the agents it drives.
- AgentOptions.systemPrompt is deleted with all its forwarding plumbing:
  the app configs' systemPrompt keys become 'persona' routed through
  dsh-agent-core (schema = z.intersect of the owners'), the ACP bridge
  and tool-subagent stop carrying persona configuration, and subagent
  children now render the deployment persona like every other agent.
- Example personas drop transport/interface trivia (ACP, CLI) — facts
  irrelevant to the model.
- Root CONTEXT.md removed (not idiomatic); its persona definition was
  wrong under the new ownership anyway.
- Docs, READMEs, the prompt-variables RFC, and generated catalogs
  updated; new loop test pins the assemble-waterfall escape valve
  (an emptied assembly sends NO system field).

Tianyi Cui 2304f7a245 Merge origin/master: adopt the DeepSeek Harness SDK product name
Reconciliations beyond textual conflicts:
- product rename (DeepSeek Code -> DeepSeek Harness SDK) applied to the
  PR-added assertion in system-prompt.spec.ts that master's rename
  commit could not reach
- architecture.md: master's rewrite kept; this PR's prompt-assembly
  semantics re-added in the new doc's voice (Turn Flow footnote +
  service-spine row), within the 1630-word ceiling
- cordis catalog regenerated into master's split events.md/services.md
  (events-and-services.md deleted); module graph and doc graphs
  regenerated to pick up this PR's new events and dependency edges

Tianyi Cui 00cf8b693a feat(agent-loop): open every prompt with the harness identity section
A static harness:identity section at order -100 — the first occupant of
the documented negative band — states that the agent is powered by the
DeepSeek Harness SDK before the deployment's persona renders. Harness
attribution is a harness fact: it lives on the loop plugin, not in each
deployment's persona, so every agent (subagents included) carries it and
no YAML can forget it. A deployment that must drop it can remove the
section in the system-prompt/assemble waterfall.

Order-band docs updated in all five homes (PromptSection JSDoc, the
system-prompt and agent-loop READMEs, architecture.md, the RFC).

Tianyi Cui 2f191cc72b docs(agent): state the persona's template contract in its JSDoc
The AgentOptions.systemPrompt doc said the persona 'may reference'
variables without saying that every complete {{...}} group IS interpreted,
strictly, and that literal {{...}} prose has no escape syntax yet (the
RFC's recorded deferral). A persona author reads this line first; it now
carries the contract. (ds-review-bot inline finding: the escape mechanism
itself stays deferred per the RFC — pre-release, no external consumers,
and the failure is loud with the fix in the message.)

Tianyi Cui e85e21c8b0 fix(review): close interpolation strictness holes; make tool-subagent mirror provider lifecycle
Codex round-1 findings, both confirmed:

- renderPrompt: variable lookup now uses Object.hasOwn (an unregistered
  {{constructor}} previously resolved through Object.prototype and spliced
  function source into the prompt), and a {{ that opens no complete group
  while a }} still follows ({{{model}}}, {{a{b}}) now throws instead of
  passing or partially interpolating. A lone {{ with no }} after it stays
  verbatim; substituted values are never re-scanned.
- tool-subagent: the apply-time provider lookup assumed a load order the
  cordis Loader does not guarantee (siblings start concurrently). The seam
  now announces subagent/provider-added/-removed and the tool mirrors the
  provider's lifecycle: registers when the provider is (or becomes)
  available, unregisters when it goes away, re-derives wording on reload.
  No load-order requirement remains.
- loop.spec containment test now proves live continuation: after the
  contained render failure, a waterfall listener rescues {{cwd}} and the
  same agent completes a real model turn.

RFC/READMEs updated to the shipped contract; cordis catalog regenerated.

Tianyi Cui f256f3961d feat(system-prompt): prompt variables, persona-as-section, tool-guidance ownership
One principle: every fact in the assembled prompt has exactly one owner.

- dsh-system-prompt: merge-extensible AssembleContext on assemble();
  a variable(name, provider) registry; {{name}} interpolation in
  renderPrompt, strict (unknown/valueless/malformed references throw);
  duplicate section and variable names rejected; assembly carries
  resolved section text + variables through the assemble waterfall.
- dsh-agent declares AssembleContext.agent; dsh-agent-loop registers
  the agent:persona section (order 0 - identity renders before tool
  guidance) and the model/cwd variables, and drops its string join:
  renderPrompt(assembly) IS the full prompt.
- Tool guidance moves to its owners: descriptions carry per-tool
  semantics; sections only cross-call habits (tool:bash exit-code
  habit at order 105; read's not-shell nudge). todo/subagent need no
  section - their descriptions already carry the contract.
- SubagentProvider.inheritsParentContext (spawn/acp false, fork true);
  dsh-tool-subagent derives truthful per-provider wording and resolves
  the provider at load (backend must be listed first).
- Example personas shrink to identity + behavior with {{model}} (and
  {{cwd}} in the ACP tree); the welcome banner stops enumerating tools.

Tianyi Cui a23982b30a Regenerate catalog for post-merge line shifts; drop pruned continuation trigger from turn/start JSDoc
Merging master brought the producerless-vocabulary prune that removed
TurnTriggerMap's continuation variant: the source pointers above
SessionEventMap shifted by one line (the staleness CI caught on the
merge tree), and the new turn/start JSDoc still named the pruned
variant.

Tianyi Cui 2728e3bd5b Close remaining keyof-join holes the review verification found
- The owning top-level interface SessionEventMap must now be the SINGLE
  EXPORTED declaration in @deepseek-ai/dsh-session: a non-exported local
  interface (even inside the owning package) and a second exported copy
  are hard errors, so a same-named helper can no longer be catalogued as
  the on-disk vocabulary.
- Any SessionEventMap declaration carrying an extends clause is a hard
  error: inherited keys join keyof SessionEventMap but have no catalog
  row, so heritage is a silent-skip path the gate must reject.

Three new spec cases; RFC and module doc updated to match.

Tianyi Cui 53dc3c8a28 Harden generator against Codex review findings
- A SessionEventMap member that is not a property signature with an
  explicit payload type is now a hard error instead of silently skipped —
  a method-form or type-less member joins keyof SessionEventMap and must
  not escape the catalog.
- A top-level interface SessionEventMap outside @deepseek-ai/dsh-session
  (ownership read from the package manifest) is now a hard error — an
  unrelated same-named local interface was previously catalogued as the
  on-disk vocabulary.
- JSDoc tag detection runs on the trimmed line, so an extra-indented
  '*  @mode' can no longer bypass the forbidden-tag check and leak into
  prose.

Four new spec cases cover these; RFC and module doc updated to describe
the enforced (not just assumed) invariants.

Tianyi Cui 232f314c3a Add generated persistence log event catalog with freshness + completeness gates
docs/persistence-catalog/log-events.md enumerates every SessionEventMap
member — the owning dsh-session vocabulary plus the dsh-compact and
dsh-hook-protocol declaration merges — with payload, surface/log-only badge,
JSDoc prose, and declaration site. scripts/gen-persistence-catalog.ts is a
pure AST pass in the gen-cordis-catalog mold: verify-persistence-catalog
(--check) joins doc-sync, so a stale committed catalog fails pre-push and CI.

The walk enforces JSDoc completeness (every member needs description prose;
@mode is rejected as a category error — log events do not dispatch on the
cordis bus), derives the surface badge from the SurfaceEventType union with a
stale-member cross-check, and hard-errors on duplicate declarations. Payloads
render through the TypeScript printer so newline-separated multi-line type
literals still emit valid one-line fragments.

Documented the five previously JSDoc-less core events (turn/step boundaries,
tool/call), removed the two stray @mode tags on the hook/* merges, and
replaced the hand-restated event enumerations (session.md hook/* table,
compact README table, hook-protocol README bullets, session README name-list
— whose merge note had already drifted) with links to the catalog. RFC:

Tianyi Cui d752eed88b Cover the remaining gate guards with focused tests
Codex review: the RFC claims the fixtures prove each guard fires, but the
binding-pattern guards (events + services), the service no-prose branch,
and the empty-@param/@returns-description branches had no focused tests.
Add the five missing cases; every violation branch in the generator now
has a matching fixture.
2026-07-04 19:18:11 +08:00
Tianyi Cui a29bbe1453 Add JSDoc completeness gate for the cordis surface
gen-cordis-catalog now hard-errors (aggregated, not fail-fast) when an
event lacks description prose or a payload @param, or a public service
method lacks JSDoc, a @param per parameter, a @returns on a non-void
result, or an explicit return type annotation. The this receiver and the
trailing waterfall next are exempt on events (mode machinery owned by
@mode); a stale @param naming no real parameter errors, mirroring the
@mode contradiction check. parseJsDoc now ends prose at the first block
tag (standard JSDoc semantics), so the tags never change the rendered
catalog — only Source: line pointers moved.

Fills the ~139 gaps found across the 15 surface files, extends the spec
with negative-path fixtures for every new guard plus the exemptions,
records the decision as an implemented process RFC, and extends the
AGENTS.md typed-events bullet with the authoring rule. Runs inside
verify-cordis-catalog -> doc-sync, so CI and pre-push enforce it with
zero new wiring.

Tianyi Cui 5a8234643a refactor(llm): drop the inert request knobs — prefill and strict
GenerateOptions.prefill had no production setter and both adapters
rejected it with LlmError('UNSUPPORTED') — its entire observable
behavior was two throws, each pinned by one adapter test. DeepSeek's
chat-prefix completion is a Beta feature on a base URL neither adapter
targets. ToolSchema.strict was threaded through defineTool, the
registry's schemas() allowlist, the deepseek wire mapping, a per-tool
payload-patching pass in the pi-ai adapter, and a tool-catalog render
row, yet no shipped tool set it and the internal endpoint story for
strict mode was never built.

Remove both fields end-to-end: the vocabulary in dsh-llm, the adapter
guards and wire branches, the dsh-tools threading, the tool-catalog
Strict row, the pinning tests, the core.md pastes, the adapter README
rows, and the cookbook line that used prefill as the UNSUPPORTED
example (now stated generically). The pi-ai payload fixup keeps the
half with a job: pi-ai stamps strict:false on every serialized tool,
so the fixup scrubs it unconditionally for wire parity with the
hand-rolled twin (per-tool set/delete machinery gone). temperature/
stop/maxTokens are untouched — honored end-to-end by both adapters.

Each knob returns with its first real producer: prefill with an
adapter that implements chat-prefix completion, strict with a tool
that wants it and a beta-endpoint story.

RFC: docs/rfc/implemented/simplification/2026-07-04-drop-inert-request-knobs.md
(moved from proposed/, amended to shipped reality); the content-block
vocabulary RFC's consequence line now records prefill as producer-gated.

Tianyi Cui 3567d000c4 refactor(vocab): prune producer-less variants — cache hints, agent source, continuation trigger
The vocabulary maps grow by declaration merging, and the admission policy
stated on TurnEndReasonMap is that a variant lands with its first emitter.
Three declared items had no producer and no consumer:

- CacheHint and the cache?: CacheHint fields on TextBlock/ToolResultBlock:
  nothing constructs a block with cache:, and neither adapter reads .cache —
  DeepSeek prompt caching is automatic (hints map OUT of responses, never IN).
- MessageSourceMap.agent: zero constructors; the subagent backends send the
  parent prompt with no source (logs as user), and the envelope renderer
  interpolates source.kind without routing on it.
- TurnTriggerMap.continuation: the loop structurally cannot emit it —
  continuation is further steps within a turn, never a new turn — and its only
  writer was an llm-replay test fixture that needed any non-message trigger
  (now an injection trigger).

Each variant returns the day it gains a real producer, via the same
merge-extensible maps. Docs updated in the same change: the MessageSourceMap
paste in core.md, the TurnTriggerMap paste in session.md (manifest untouched —
both symbols survive), the content-block vocabulary RFC's cache-hints
consequence line, and the RFC moved to implemented/ and amended to shipped
reality (the image block's own cache field had already left with the
drop-image RFC).

Tianyi Cui c6d2eeea6b refactor(events): remove the agent/steering mirror emit
agent/steering was the last transient mirror of a durable session event:
drainSteering appended the durable steering/message {turn, content, source}
and emitted the identical fact one line later. Zero production listeners
existed — every steering consumer (hook bridges, goldens, deriveMessages)
reads the durable event — and the one regression test subscriber asserted
a fact the log already records.

Remove the declaration (dsh-agent types + JSDoc list + README row), the
emit in drainSteering (its ctx parameter goes too), and the emit line in
the loop-pseudocode blocks (loop.ts module doc, architecture.md); the
cordis catalog is regenerated. The regression test now pins source
preservation on the durable steering/message event. Live-notification
needs keep their surviving homes: agent/queued at enqueue time,
session/event at drain time.

RFC: docs/rfc/implemented/simplification/2026-07-04-remove-agent-steering-mirror.md
(moved from proposed/, amended to shipped reality). The three implemented
RFCs that stated the retention — the boundary-mirror removal, the
stream-chunk removal, and event-domain-semantics — are amended to point
at that RFC as the record of the removal, per implemented/AGENTS.md.
The rejected retire-mid-turn-steering RFC keeps its frozen text (it
records the declined proposal); the steering capability itself —
steer(), the durable event, continuation forcing — is untouched.

  safety and documentation — the generated-catalog RFC cites it as the
  rule the generator enforces at the source.
- Repoint the six remaining citations of moved content that the
  section-name grep missed (rule-title quotes and prose references):
  agent-loop agent.ts, acp index.ts, acp turns.spec.ts, the Exa e2e
  header, the real-api-e2e RFC, the doc-sync-enforcement RFC amendment,
  and rfc/implemented/AGENTS.md's section-name casing.
- Fix two docs/testing.md overstatements: the unit tier also runs
  examples/*/tests specs, and keyless-by-nature examples have no
  with-key smoke.
- Displacement trims keep root AGENTS.md at 1,498/1,500.

Tianyi Cui fb78a844af docs(tools): fix cross-module JSDoc links and the catalog source list
Codex review of the vocabulary relocation found two doc-accuracy issues:

- presentation.ts's JSDoc used {@link ToolDefinition...}, which the
  TypeScript language service cannot resolve because presentation.ts
  deliberately does not import index.ts (that would create the cycle the
  split avoids). Demote those three to plain `ToolDefinition` code text;
  same-file and imported @links (TerminalResultView, ContentBlock) stay.
- docs/core-data-structures/tools.md's source header listed only index.ts
  and schema.ts; add presentation.ts, which now owns the presentation
  vocabulary the page documents.
2026-07-04 00:39:09 +08:00
Tianyi Cui 539051b2c9 refactor(tools): move render-intent vocabulary to presentation.ts
The tool render-intent vocabulary (ToolCallView/ToolResultView + members,
FileLocation, FileDiff, ToolCallKind) is the UI-facing surface of
dsh-tools; it lived inline in index.ts alongside the registry and
execution core. Move it to its own presentation.ts module so index.ts is
the registry + execute waterfall and the presentation vocabulary is a
separate, one-directional dependency.

presentation.ts owns ONLY render-intent types and references none of the
execution types; index.ts imports the view types for ToolDefinition's
presentCall/presentResult signatures (clean acyclic index -> presentation).
The opaque `meta` presentation channel (ToolExecuteReturn, ToolResult,
ToolExecutionResult) is execution plumbing and stays in index.ts.

Public surface unchanged: index.ts re-exports the vocabulary, so consumers
(tool-fs/tool-bash/tool-web/tool-todo, the ACP bridge) keep importing from
@deepseek-ai/dsh-tools with zero churn. No producer/bridge/test edits; a
pure internal relocation with no observable-output change (snapshot goldens
untouched).

Tianyi Cui e07886599c docs: finish the whole-file-diff sweep across comments and RFCs
Codex's stale-prose pass found seven more spots still describing the
result diff as ALWAYS an applied contextual hunk, or a create/binary
overwrite as rendering "only the call-time card": the DiffCallView JSDoc
and the acp bridge diff-arm comment, the FsWriteOutcome.before and
readTextForDiff JSDoc, and three RFC lines. All now say: the result diff
is the applied change — a contextual hunk when there is a before-image,
else a whole-file diff (create / undiffable binary) — and a successful
mutation always returns the result diff so the model-facing text can't
clobber it. Regenerate the cordis catalog (source line shift).

Tianyi Cui da1d7f281d docs(tools): DiffResultView.diffs may be a whole-file diff, not only hunks
The write-diff-card fix made write's presentResult return an args-derived
whole-file diff (oldText:null) for a create / unchanged overwrite, but the
DiffResultView contract and its mirrored docs still said `diffs` is ALWAYS
the applied contextual hunks computed from before/after. Correct the type
JSDoc, the write execute-side comment, and the four mirrored surfaces
(tools.md, tools README, acp-feature-support, adding-a-tool cookbook) to
say: typically the applied hunks, or a whole-file diff when there is no
before-image (a create) — and that a mutation returns the diff result even
when it duplicates the call-time card, since a tool_call_update.content
replace would otherwise clobber the diff with the model-facing text.
Regenerate the cordis catalog (source line shift).

Tianyi Cui dee2dee402 fix(tool-fs): CRLF-safe write diff, opaque meta, doc sync
Address the applied-hunk-diffs review:

- CRLF write overwrite emitted bogus every-line-changed hunks: write's
  `before` was LF-normalized but `after` kept the raw model content, so a
  CRLF rewrite of an LF file diffed every line. Normalize write's `after`
  to LF so both sides share the diff basis (edit already did). Regression
  test proves it fails on the raw-after path.
- The tool-private `meta` payload is now typed `unknown` (opaque) at every
  seam instead of `JsonValue`. This drops the `dsh-tools -> dsh-session`
  package edge that existed only to name the type, and removes the
  `FileDiff` index signature that had been widening the type solely for
  JsonValue-assignability. Serializability is still enforced at runtime by
  `Session.append`'s isJsonValue check, which was always the real guard.
- Sync the docs the new result/meta surface left stale: ToolResultView's
  diff card + ToolExecutionResult.meta in tools.md/session.md type-equiv
  blocks, the acp/tools READMEs, and the adding-a-tool cookbook; regenerate
  the cordis catalog and module graph.

Tianyi Cui d8fd3225af feat(tool-fs): result-time applied-hunk diffs for write/edit
fs write/edit now emit a result-time contextual-diff tool_call_update
(the applied hunk with ±3 context lines, one hunk per replace_all site),
matching what claude-agent-acp sends and what makes an editor render the
change in place. The call-time snippet diff stays; the result hunk
supersedes it (ACP content-replace).

Mechanism:
- A persisted tool-private `meta` channel: execute may return
  `{ content, meta }`; `meta` (JsonValue) rides on the tool/result event
  and is handed back to presentResult, so the diff reproduces on replay
  (event-sourced). JsonValue is now exported from dsh-session.
- The backend returns raw before/after text (storage facts) on
  FsWriteOutcome/FsEditOutcome; the tool computes the hunk via the npm
  `diff` package's structuredPatch. A create has no before → no result
  diff; a failed/aborted mutation carries no meta.
- ToolResultView gains a DiffResultView; the bridge's result-side switch
  renders it as {type:'diff'} content blocks.

RFC: docs/rfc/implemented/architecture/2026-07-02-result-time-applied-hunk-diffs.md
(justifies the npm `diff` runtime dep over vendoring and the meta channel);
the render-intent-union RFC's Non-goal is updated to record this shipped.
All fs snapshot goldens re-recorded; edit/overwrite gain the contextual
result diff, create/read/policy-reject unchanged in structure.

Tianyi Cui 1a57d67058 refactor(tools): tagged render-intent union for tool-call presentation
Replace the "bag of optional fields" tool-presentation types
(ToolCallPresentation / ToolResultPresentation / ToolTerminal) with a
card-tagged discriminated union — the standing FIXME(tool-presentation).
A tool declares one render intent per call/result and the ACP bridge
switches on `card`:

  ToolCallView   = generic | terminal | diff
  ToolResultView = generic | terminal

The `diff` card is new: fs write/edit now emit an ACP {type:'diff'}
content block (an editor's inline diff), which the old shapes could not
express. The bridge also relativizes a file card's title against the
session cwd (mirroring claude-agent-acp's toDisplayPath) while keeping
locations/diff paths raw, and derives the no-capability fenced console
fallback from a terminal result's output. read gains the window-in-title
(`Read foo.txt (5 - 8)`) and an always-set location line, matching the
reference adapter field-for-field.

Migrates all three producer families (tool-fs, tool-bash, tool-todo) and
the sole consumer (the ACP bridge) together — the source does not compile
piecewise. Adds snapshot coverage for the terminal _meta path (a new
capability-advertising scenario) and re-records the fs goldens to show the
diff cards. Applied-hunk (result-time, context-line) diffs need a new
result/event shape and are a follow-up.

Tianyi Cui 5481887cd3 docs(agent): point the streaming reader at session/event assistant/chunk
Follow-up to the README fix: the dsh-agent README's emit section had lost its
streaming entry, leaving a "Streaming + tool" heading with no pointer to where
the token stream now lives. Rename the section to "Live control notifications"
and add a line directing readers to the durable `session/event` `assistant/chunk`
feed.

Tianyi Cui e100c52154 docs(agent): drop agent/stream-chunk from the two package READMEs
Codex convergence caught stale prose the doc-sync gate does not scan: the
dsh-agent README still listed `agent/stream-chunk` as an emit and the
dsh-agent-loop README still told UI plugins to listen on it. A plugin author
following either would silently get no chunks. Point both at the
`session/event` `assistant/chunk` feed (the agent-loop UI line also names the
`agent/*` control events a UI still uses).

Tianyi Cui b84d4828a8 refactor(events): remove the agent/stream-chunk mirror of assistant/chunk
The loop recorded every model token delta as a durable `assistant/chunk`
session event AND emitted an identical live `agent/stream-chunk` Cordis event
one line later. Same StreamChunk, same turn/step; the emit added only the live
Agent handle, which the sole consumer discarded. This is the boundary-mirror
duplication the event-domain work removed for turn/step boundaries, applied to
the token stream — a follow-up the boundary RFC explicitly deferred.

The premise is settled: chunk persistence is authoritative (the proposal to
stop persisting chunks was rejected — replay/snapshots depend on it), so
`assistant/chunk` on `session/event` is the load-bearing token stream and
`agent/stream-chunk` is pure redundancy.

- Remove the `agent/stream-chunk` declaration + emit; drop the now-unused
  StreamChunk import from dsh-agent's types.
- Migrate `dsh-ui-stdio` (the only live consumer; ACP already reads
  assistant/chunk off session/event) to render assistant/chunk in its existing
  session/event listener. Consolidating to one listener also makes the
  inReasoning dim-SGR flag deterministic across chunk/boundary events (they no
  longer race across two listeners).
- Repoint the agent-loop tests (cancel/loop) and ui-stdio tests to the
  session/event assistant/chunk feed.
- New RFC (implemented/simplification/2026-07-02-remove-stream-chunk-mirror);
  amend the boundary RFC's retained-list entry to cross-link; update
  architecture, cookbook, event-domain-semantics, the ACP proposal, and the
  regenerated cordis catalog.

Snapshot goldens unchanged (ACP never used the mirror), confirming no
editor-facing transcript change.

Tianyi Cui bd7fb31ae3 feat(tool-fs): editor-facing presentation for read/write/edit
The fs tools rendered as generic cards (title = tool name, raw file content) in
an ACP editor. Give them tool-owned presentation like bash/subagent have:

- read → title "Read <path>", kind read, offset/limit as rawInput
- write → title "Write <path>", kind edit
- edit → title "Edit <path>", kind edit, a clipped old→new rawInput summary

Add a provider-neutral `locations: { path, line? }[]` to ToolCallPresentation —
the files a call reads/modifies — so a capable editor can follow along / jump to
the file (read carries its offset as the line). The ACP bridge forwards it onto
the wire `tool_call` (ResolvedCallPresentation + call() + the tool_call build in
streamSessionEventUpdate). This flips the `locations` cell in the ACP feature
matrix to supported. The SDK already carries `tool_call.locations`
(ToolCallLocation `{ path, line? }`), so no ACP types leak into dsh-tools.

presentResult is intentionally omitted: it only receives `{ content, isError }`,
not the write/edit outcome, so titling by create-vs-overwrite or replacement
count would mean parsing the model-facing text — the static title stays.

Tests: pure presentCall assertions for all three tools incl. locations and the
edit rawInput clip; a bridge test drives the REAL fs tools through ToolPresenter
and asserts locations reaches the wire tool_call (proven to fail without the
forwarding line). New withFs harness option + dsh-fs devDeps on dsh-acp.

Tianyi Cui abe80cec68 fix(loop): record a durable prompt/blocked for every vetoed prompt
Address review on the interception-seams PR: PromptDecision.reason is
documented as the durable record of why a prompt was blocked, but the loop
only surfaced it via the fully-blocked batch's `rejected` turn/end. In a MIXED
batch — one queued prompt blocked, another allowed — the turn does not end
`rejected`, so the blocked prompt and its reason vanished from the session log
entirely.

Add a `prompt/blocked` SessionEventMap variant (content + source + reason),
appended in the open turn at the veto point in place of the user/message the
prompt would have become. It is a non-surface, turn-enclosed event (like
todo/write): it never reaches deriveMessages(). The fully-blocked batch still
also ends `rejected` for boundary balance + ACP settlement. Regression test
drives a mixed batch and asserts the blocked prompt is recorded while the
allowed one runs — proven red without the append.

Tianyi Cui 1e87b6fea4 fix(ui-stdio): seed turn labels from the registry; drop stale taxonomy line
Address review on the event-taxonomy PR:

- ui-stdio built its session-id→agent-id label map only from live
  `agent/created` events, so an agent registered before the UI fiber
  installed — the pre-created `main` agent, or any agent surviving an HMR
  reload of just this fiber — was missed and its turns rendered the raw
  session id instead of `[main turn N]`. Seed the map from
  `ctx.agents.list()` at install, then keep it live. Regression test proven
  red without the seed.
- The agent event-domain doc still listed "the turn boundaries" among the
  TRANSIENT `agent/*` emits, contradicting the rule ten lines below that a
  turn/step boundary is a durable `session/event`, not an `agent/*` mirror.

Tianyi Cui 6c88b380ea docs(tool-catalog): register dsh-tool-fs in the boot manifest
Master's new tool-schema catalog boots every tool-* package and hard-errors if
one is absent from the manifest. Add the dsh-tool-fs entry (boot dsh-fs-local to
satisfy the injected `fs`, harvest read/write/edit), note that dsh-fs-policy adds
the read-before-write/edit gate without changing schemas, and regenerate
docs/tool-catalog/tools.md. Update the collectToolCatalog test's expected tool
set to include the fs tools.

Tianyi Cui d3be934a17 docs(events): fix stale turn-mirror / tools-execute prose caught in review
Codex review of the interception-seams merge flagged current-state prose still
describing removed/renamed surfaces:

- packages/core/agent/src/types.ts module doc: the agent/* "transient emits"
  list still ended with "the turn boundaries" — corrected to state turn/step
  boundaries are durable session/event records, not agent/* emits, and to list
  the actual interception seams (prompt-submit/pre-step/request/step-result/
  turn-continuation) + agent/session-start.
- interception-seams RFC: "agent/turn-end fires and the ACP bridge settles" →
  the durable turn/end is appended and ACP settles off it (no turn mirror).
- two proposed RFCs (acp-agent-client-protocol, optional-code-mode) named the
  pre-split `tools/execute` waterfall → the `tools/pre-execute`/`tools/post-execute`
  pair.

Regenerated the cordis catalog (module-doc change). No code/behavior change.

Tianyi Cui 1323366da3 Merge worktree-hooks-b-bash-seam into worktree-hooks-c-interception
Bring the interception-seams branch onto current master (via A→B). The
substantive reconciliation is master's compaction `agent/pre-step` serial seam
meeting C's interception seams:

- types.ts: keep BOTH master's `agent/pre-step` AND C's new interception events
  (`agent/prompt-submit`, `agent/session-start`, `agent/turn-continuation`→
  `ContinuationDecision`); drop the turn-mirror declarations (removed on A).
- loop.ts: the merged per-turn order is `turn/start` → per queued msg
  `agent/prompt-submit` (rewrite/inject/block) → (fully-blocked ⇒ zero-step
  `rejected`) → per step: drain steering → assemble system prompt →
  `agent/pre-step` (compaction, OUTSIDE the step) → `step/start` → single
  `deriveMessages()` → model → tools/pre-execute·dispatch·post-execute. No
  turn-mirror emits; `closeTurn()` is the A-simplified single-call form.
- Docs (architecture, core.md, agent/agent-loop READMEs, catalog) reconciled to
  show C's interception seams alongside `agent/pre-step`, no turn/step mirrors.
- rfc/README: dropped the stale `proposed/` compaction row (master moved that RFC
  to implemented/); kept C's new `pre-tool-input-rewrite` proposed row.
- interception.spec.ts: migrated its two `agent/turn-end` reason collectors to
  the `turn/end` session event, and ADDED a cross-test proving a
  `prompt-submit` rewrite + additionalContext is VISIBLE to an `agent/pre-step`
  listener on the same turn — pinning the merged seam ordering (compaction sees
  the post-prompt-submit surface, not stale history).

Tianyi Cui 9e575a2a2c docs(events): fix stale turn-mirror references caught in review
Codex review of the turn-mirror removal found current-state docs/comments that
still claimed the removed `agent/turn-start`/`agent/turn-end` events exist:

- docs/architecture.md: the loop diagram's turn-start line still said "emit
  agent/turn-start" (the turn-end line was already fixed).
- event-domain-semantics RFC: the `agent/*` domain description listed "the turn
  boundaries" among the transient emits.
- docs/core-data-structures/core.md: the agent/* taxonomy blurb listed
  "turn/step boundaries" as agent events.
- the proposed ACP RFC: the settle-signal rows named agent/turn-start /
  agent/turn-end; retargeted to the durable `turn/end` session event + the
  session/event owning-turn correlation.
- loop.ts outer-catch comment: said "closeTurn/failTurn are idempotent" — after
  the emit-param removal closeTurn is called exactly once (mutually exclusive
  normal/catch paths), so corrected to state that and to scope idempotency to
  closeStep (which is still guarded by stepOpen).

Regenerated the cordis catalog. No behavior change.

Tianyi Cui 140f818a42 refactor(events): remove the turn boundary mirror events
Complete the boundary-mirror removal begun with the step mirrors: drop
`agent/turn-start` and `agent/turn-end` from the agent event taxonomy. Turn and
step boundaries are now read exclusively off the durable `session/event` feed
(`turn/start`/`turn/end`/`step/start`/`step/end`) — there is no `agent/*` mirror
for any boundary.

- loop.ts: delete both turn emits; `closeTurn` loses its `emit` parameter and
  its now-unreachable idempotency guard (it is called exactly once per turn, on
  mutually exclusive normal/catch paths); `failTurn` loses the dead post-close
  branch that only a throwing turn-end LISTENER could reach.
- ui-stdio: render turn boundaries from `session/event`, recovering the short
  agent label from an `agent/created`→id map (the `turn/start` event carries only
  the turn number, and the session id is not reliably the agent id). ui-stdio is
  a disposable test REPL, so this migration retires the sole justification the
  event-domain-semantics RFC gave for KEEPING the turn mirrors.
- Tests: reason/turn-number collectors and the boundary-ordering test now read
  `session/event`; the throwing-turn-boundary-LISTENER tests are deleted (that
  code path no longer exists). A new test covers the outer-catch disposed branch
  via a pre-step listener that disposes-then-throws (the surviving real path).
- Docs: promote the "remove agent boundary mirror events" RFC to implemented
  (amended/narrowed — `agent/steering` is RETAINED, not a boundary mirror);
  update the event-domain-semantics + turn-enclosure RFCs, architecture.md, the
  cookbook, the ACP/agent/ui-stdio prose, and regenerate the cordis catalog.

`agent/steering` and `agent/stream-chunk` are explicitly out of scope (not
durable-boundary mirrors). ACP is unaffected — it already settles from the log's
`turn/end` + `agent/status`; snapshot goldens are byte-unchanged.
