1f35a4446d fix(compact): address PR 110 review findings
Honor cancellation and disposal around async pre-step setup before the loop can open a step or call the model.

Route compaction summarization through agent/request so router agents can select the model, and remove the stale model argument from agent/pre-step.

Document serial events and the approximate convergence bound, regenerate the Cordis catalog, and add regression coverage for router compaction, HMR cleanup, and assembly/pre-step interruption.

55088d1cfc docs(AGENTS): require running the CI gates locally before marking a PR ready
Add a "Run the CI gates locally BEFORE marking a PR ready" subsection: the
CI-equivalent local command line, and the rule that `pnpm run test:coverage`
(per-file 100%, CI-enforced) — not `pnpm run test` — is the gating test command,
alongside hygiene/snapshot/doc-sync. A green `test` run can still fail CI on an
uncovered line, which is usually dead code the gate is correctly flagging.

46e31d8481 feat(tool-todo): add the model-facing todo_write tool
Add @deepseek-ai/dsh-tool-todo (a new packages/todo/ group): a model-facing
todo_write(todos: [{content, status}]) tool with whole-list-replace semantics.
Each call appends the full list as a todo/write event to the calling agent's
session log; the current list is the most recent such event (last-write-wins).
Single-owner — a non-agent caller is rejected. Beyond the schema's
type/required/enum checks, execute rejects empty/duplicate content and more than
one in_progress task, narrowing the loosely-typed args into a real TodoItem[].

Both UIs render off the existing session/event: the stdio UI prints a glyphed
checklist; the ACP bridge maps the list to a `plan` sessionUpdate (todosToPlan
synthesizes the priority ACP requires; status maps 1:1). Wired into the
coding-agent, acp-agent, and snapshot example configs with a system-prompt nudge.

Tests: unit (schema, validation, append/replace, no-agent rejection, presentCall,
HMR-safety, Loader export-shape guard), full-loop integration through the agent
loop, the ACP todosToPlan mapping + stream-update arm, the stdio render arm, and
a session/load replay that re-emits the plan. New-group TS wiring added to
tsconfig.base/json/build. RFC + a doc-inventory sweep (architecture, packages
README, AGENTS layout, cookbook group list, example READMEs) ship with it.

The todo-plan ACP snapshot scenario is recorded separately (needs an API key).

ef37ce3b9d refactor(fs): split filesystem seam into provider ctx.fs + policy ctx.fileContext
Implements the split-the-filesystem-seam RFC. ctx.fs shrinks to a text-storage
provider seam (resolve/stat/readText/streamText/writeText/editText with branded
FsTargetKey/FsVersion and an explicit FsWriteExpectation); the new
dsh-file-context package owns the model-facing policy (read windowing,
observed-state, write/edit freshness) as the concrete ctx.fileContext service.

Authorization is now freshness-based rather than full/partial view: a windowed
read records the file version and authorizes a later edit when the file is
unchanged, removing the dead-end where reading lines 100-150 of a large file
could not edit line 120. editText stays a provider primitive so version guard +
literal match + atomic rewrite remain one critical section, and the stale check
runs before matching so a stale edit reports FS_STALE_VERSION. tool-fs injects
fileContext, never reaching around to ctx.fs (the no-bypass contract).

7aabd2a3df Add in-process subagent backends: spawn (fresh) and fork (seeded)
The second PR of the subagent seam: the two in-process backends that run a
child agent on the same cordis context, reusing the agent factory's quiescent
AgentHandle teardown. Both register on ctx.subagents (PR1's named-provider
registry) and share one run driver.

- dsh-subagent-spawn: a FRESH child via ctx.agents.create — own session, the
  parent's model by default (overridable), zero inherited conversation. Also
  exports the shared in-process run driver (startInProcessRun): mint ids, stamp
  cwd/parentSession-lineage/depth, drive the one-shot (send → whenIdle), read
  the last assistant/message + turn/end reason, dispose to quiescence.
- dsh-subagent-fork: a child SEEDED with the parent's balanced completed-turn
  prefix (the log up to and including its last turn/end), so the child inherits
  context. The in-flight unbalanced turn is excluded — a raw seed would fail the
  invariants replay. Proven: a regression test goes red if the boundary seeds
  the open turn.
- Seam extension: CreateAgentOptions.seed, threaded through AgentLoop.createAgent
  → ctx.sessions.prepare({ seed }) (the primitive resume already used). This is
  the fork-lineage path the TODO(sub-agents) markers anticipated.
- Depth: a merge-extensible AgentOptions.subagentDepth (0 top-level, parent+1 for
  a child); the depthLimit capability refuses a spawn past request.maxDepth.

Tests: real-loop unit tests for both backends (mock MODEL only, real loop +
invariants), a multi-subagent test (one parent drives a fork AND a spawn child
then keeps working), and a with-key e2e (a real parent delegates via the
`subagent` tool to a real child that writes a file on disk — world-verified).
100% per-file coverage. The coding-agent demo wires the spawn backend + tool.

Snapshot coverage of nested agents is deferred to a stacked follow-up
(TODO(subagent-snapshots)): dsh-llm-replay is a single global positional cursor
that cannot route calls to a parent vs. a child on one context. Recorded in the
RFC's deferrals and a new AGENTS.md rule: designing a subsystem must design its
test infrastructure END TO END up front, verifying the snapshot/e2e harness can
express the new shape — a gap this plan hit.

a96b1e3ae7 docs(agents): capture stacked-PR orchestration + sharper real-entry-path lessons
Three hard-won lessons from running a 7-PR simplification stack through two
waves of review feedback:

- New "## Orchestrating review feedback across a stacked PR chain" section: one
  worktree per branch; a fix belongs on the PR that introduced the issue then
  flows DOWN; review-fixes are separate commits never amends; delegated work is
  trust-but-verify (prove a regression guard FAILS on unfixed code); reply
  in-thread on the merits.
- "## Conventions" gains a "Never rewrite a pushed branch" rule next to the
  merge-commit rule: update a child by merging the parent down, never
  rebase/amend/force-push a pushed branch; a fix lands on its originating PR.
- Extended the "Line coverage is not behavior coverage" defensive-patterns
  bullet with two corollaries this stack re-taught: (1) a real-load-path test
  only GUARDS the export shape if a broken shape actually FAILS it — an
  inject-less composition plugin boots fine on a stray `export default`, so it
  needs an explicit no-default + unwrapExports assertion; (2) "real entry path"
  means the PUBLISHED artifact (built lib/bin.js under plain node), not the dev
  runtime (tsx), which masks boot settle-races, module-resolution differences,
  and a load failure that loader.await()'s Promise.allSettled swallows.

e2bde2902c refactor(examples): extract the app spine into dsh-agent-core + app packages
Implements docs/rfc/.../2026-06-20-extract-example-app-packages.md. Each
example was thick — a hand-rolled start.ts, an infra preamble, nested
base.yml/base-core.yml/acp-tail.yml includes, and a coupled front-door
cluster enforced only by prose. This moves the composition into packages so
each example is a thin leaf cordis.yml: pick the swappable backends, load one
app package.

New packages:
  - @deepseek-ai/dsh-agent-core (packages/core/agent-core): one bundle plugin
    that loads the providerless/executor-less/UI-less spine (timer + llm +
    sessions + system-prompt + tools + agents + invariants + tool-bash +
    agent-loop) via ctx.plugin(...) inside apply(), and forwards agent-loop's
    `agents` list as its own Config (export const Config = AgentLoop.Config,
    default []).
  - @deepseek-ai/dsh-stdio-agent (packages/ui/stdio-agent): terminal chat APP —
    agent-core + console logger + readline UI + a pre-created `main` agent, with
    a bin. The demo:echo/coding front door.
  - @deepseek-ai/dsh-acp-agent (packages/ui/acp-agent): ACP server APP —
    agent-core + JSONL persistence + the acp bridge, NO stdout logger, with a
    bin. The stdout-purity footgun is structurally unreachable from the leaf.

Amendment to the RFC: hmr stays a LEAF cordis.yml entry, not baked into
dsh-stdio-agent. hmr is a Loader-only dev plugin (throws without
--expose-internals; the in-process test tier can't even import its decorator
form), so a package statically importing it could never carry the per-file
coverage gate. Unlike the console logger, a stray hmr is not a stdout-purity
footgun, so leaving it at the leaf costs no safety. With hmr out, all three new
packages carry in-process unit specs at 100%.

Boot glue (Loader tail, .env load, snapshot-mode selection, stdin-dispose
lifecycle) moves into each app's bin; start.ts and base.yml/base-core.yml/
acp-tail.yml are deleted. Each app package gets a keyless real-load-path test
that boots through its bin + the cordis Loader (guarding the unwrapExports
export-shape bug class, postmortem 0001). ACP snapshot replay stays green
against the existing committed goldens (pure boot restructuring). RFC moved
proposed->implemented with the amendment recorded; package/example/architecture
docs and the module graph updated.

b0422f2a50 fix review findings: bump session format version + restore late turn-end warn
Codex review of the trace-event fold found two merge-blockers.

Blocker #1 — format version. Folding usage onto assistant/message and removing
the standalone usage/error events changed the persisted SessionEventMap shape,
which per the AGENTS.md "bump the version and reject — don't migrate" policy
requires a backend to reject any non-current log. Centralize the version in an
exported SESSION_FORMAT_VERSION constant (dsh-session), read by both write sites
(Session constructor default, SessionStore.prepare header) and the coordinator's
load-time assertVersion check. The constant is pinned at 0: while unreleased the
on-disk format is unstable/pre-release, so breaking shape churn is absorbed at v0
(no monotonic bump until the first tagged release) and any non-0 log is rejected
on load — no migration. Update every test/fixture/doc that stamps a
currently-written header to the constant, bump the ACP snapshot fixture + golden
headers to v0, and keep the version-rejection test meaningful by switching its
bad value to a clearly non-current 99. AGENTS.md documents both the monotonic
(SQLite SCHEMA_VERSION) and pinned-0 (session log) pre-release stances.

Blocker #2 — restore the late turn-end warn. failTurn now sets the error reason
only while the turn is still open; once turn/end is appended (a throwing
agent/turn-end listener after closeTurn) the reason can no longer reach the
durable log, so the late throw is logged via ctx.logger.warn instead of
vanishing into a futile post-close assignment. A regression test asserts the
warn fires.

Also guard the normal-step assistant/message append with the same
content-or-usage condition as the max-tokens branch (a content-less, usage-less
step records no trace-only row), with a covering test.

83e97ed222 fix review findings: document the util/ group + align branded-ids RFC with dsh-brand
Adding packages/util/brand/ created a new top-level packages/util/ group that
the hierarchy/dependency docs never enumerated. Document it:

- Add packages/util/README.md, the group README (low-level zero-dependency
  utilities shared across groups; lists dsh-brand).
- packages/README.md: add the util/ group to the group table, dsh-brand to the
  package table, and dsh-brand to the dependency graph. Correct the now-false
  "no harness deps" claims — dsh-llm and dsh-bash both depend on dsh-brand
  (verified dsh-bash imports Branded from dsh-brand, not dsh-llm; dsh-session
  and dsh-agent depend on it too).
- Root AGENTS.md Repository Layout: add the util/ group with brand/.

Align the implemented branded-ids RFC with what shipped: Branded lives in
@deepseek-ai/dsh-brand (packages/util/brand/), and dsh-bash depends only on
that utility package instead of dsh-llm. Fix the BashTaskId import source, the
illustrative snippet, and the opening policy reference (now dsh-brand).

c6ed980d6f fix review findings: stale abort() docs + move RFC to implemented
Codex's no-ship was a completeness/docs-sync gap, not loop behavior:

- docs/architecture.md: drop the public abort() handle row; the teardown
  signal is now cancel() then await whenIdle().
- cancel.spec.ts: the module doc and the turn-start comment contrasted
  cancel() against a public abort() verb that no longer exists — reword to
  name the loop's private step AbortController.
- packages/ui/acp/src/index.ts: the post-resume-leak comment cited abort();
  cancel() is the surviving stop verb that likewise does not unregister.
- Move the RFC proposed -> implemented/simplification with amended text:
  Status flips, the both-removal proposal is narrowed to abort-only, and an
  implementation note records why whenIdle() is retained (load-bearing
  quiescence primitive with live ACP consumers). Update docs/rfc/README.md.
- AGENTS.md "RFCs are proposals, not golden truth": add the concrete
  abort/whenIdle worked example now that the implemented RFC exists to link.
- Regenerate the cordis catalog (line-number drift from the rebase).

30cd67b8a1 simplify(llm): drop unconsumed adapter-change event and assembled call surfaces
The LLM service exposed three call surfaces (stream/streamBlocks/generate) but
the only production consumer — the agent loop — uses stream() exclusively,
feeding raw chunks through its own BlockAssembler for replay fidelity. Drop the
speculative convenience surfaces and the registry-change event that no listener
consumed, leaving stream() as the single model-call contract for both
production and tests.

- Remove LlmService.streamBlocks() and generate(), the llm/generate waterfall,
  and GenerateResult.
- Remove the llm/adapter-change event (declaration + emits) and the
  listener-throw rollback ordering that existed only to protect it; keep the
  HMR rollback disposer.
- Remove BlockAssembler.flushReady()/flushRemaining()/result() and the flushed
  cursor — the streaming-flush slice existed only for streamBlocks().
- Adapter tests drive a stream()+BlockAssembler helper (tests/assemble.ts)
  instead of generate(), exercising the same path production uses.
- Land the AGENTS.md "RFCs are proposals, not golden truth" principle and move
  both RFCs proposed -> implemented.

Implements:
- docs/rfc/implemented/simplification/2026-06-20-drop-unconsumed-llm-adapter-change-event.md
- docs/rfc/implemented/simplification/2026-06-20-drop-unconsumed-llm-assembled-surfaces.md

5024cd5757 Document the package hierarchy and finalize the RFC
Add a README to each group dir (core/llm/bash/session-persistence/ui/
support) stating its role and product-vs-support classification, and
rewrite packages/README.md around the hierarchy (group table, grouped
"what goes where", removed the package-hierarchy FIXME).

Move the package-hierarchy RFC to implemented/architecture/ and rewrite
it to describe what shipped (placement rationale, the paths-wildcard and
publint dedup, the two new guardrail gates). Fold the remaining
tsconfig.build.json references dedup into the discover-package-inventory
proposal and fix its cross-link.

Update AGENTS.md: regrouped repo-layout map, depth-2 globs, the new
verify-package-paths gate in the doc-sync listing, and a note that we
lean toward stricter lint in the agentic-coding era (machine-caught
errors and a consistent foundation outweigh the one-time cost).

ca2207e26c Fix doc cross-links for the hierarchy; add package-path + shape gates
Merge brought in the RFC-classification reorg and two new doc gates;
rewrite every drifted packages/<name> cross-link (Markdown link targets,
moved-README relative depths, and .ts comment paths) to the grouped paths.

Add two doc-sync/hygiene gates so the manual checks this restructure
needed become automated:
- verify-package-paths.ts: flags a packages/<path> reference (in Markdown
  or a .ts comment/string) that does not resolve AND names a real package
  in a segment — i.e. a stale path to a MOVED package. A path naming a
  non-existent package (a forward-looking proposal) is left alone, so it
  applies uniformly across proposed/implemented/rejected.
- check-workspace-constraints: assert the packages/<group>/<pkg> depth-2
  shape (group dirs carry no package.json; no flat or over-nested
  packages). Group names stay open; only the shape is fixed.

605587e79c docs(rfc): classify RFCs by kind via path-encoded subdirectories
Add a second axis to every RFC — its class (feature, bug-fix,
simplification, architecture, process, testing) — encoded in the path
as docs/rfc/{lifecycle}/{class}/file.md. The folder is the label, so
the closed set is enforced by structure rather than a parsed field.

Two new doc-sync gates back it:
- verify-rfc-classification: every RFC sits in a valid class folder and
  the README index lists it under the matching lifecycle→class heading.
- verify-doc-refs: every docs/*.md path cited in a packages|examples TS
  comment resolves — closes a drift class verify-md-links can't see, and
  catches the four comment refs this reorg moved.

The README gains a Classification section explaining the taxonomy and
per-class index sub-sections. A self-referential process RFC records why
the scheme is path-encoded and gated.

  member (e.g. BashExecutor.notifyTaskDone) is a subclass hook, not part of the
  public ctx.<key> surface a plugin author calls. The method filter now drops
  private, protected, and static.
- Add BashTaskRead to the type cross-link map so readOutput()'s return type
  links to its core-data-structures page.
- Reword the generator module comment and the AGENTS.md @mode rule to state the
  current capability without narrating the retired event-taxonomy verifier
  (that history lives in the RFC).

4e5c08ef82 docs: generated cordis events + services catalog
Add scripts/gen-cordis-catalog.ts: a fully-generated docs/cordis-catalog/
events-and-services.md cataloging every cordis event (exact signature + @mode)
and ctx.<key> service (exact interface), modeled on gen-module-graph's
--write/--check freshness gate. The harness tier renders in full from the
interface Events / interface Context declarations and their JSDoc; the inherited
cordis-core/loader/hmr/timer surface renders tersely from a curated table.

The generator hard-errors on a missing @mode tag and on a tag that contradicts
a conclusive signature shape (a trailing next param is structurally a
waterfall). Signature blocks use a ts cordis-catalog fence that doc-typecheck
skips. Type tokens cross-link to the core-data-structures catalog.

This supersedes the hand-maintained event-taxonomy table: verify-event-taxonomy
is deleted and verify-cordis-catalog joins doc-sync. architecture.md keeps the
Event taxonomy heading (TOC anchor) but points at the catalog; the Service-map
role table stays. RFC, AGENTS.md @mode authoring rule, and dependent doc/skill
references updated. Negative gate tests cover the missing-tag and
tag/shape-contradiction paths.

5a6243900d fix(doc-sync): close verify-type-equiv scan gap; correct persistence prose
Review found verify-type-equiv only scanned docs the manifest already named, so
a type-equiv block in an unmanifested doc was silently skipped — defeating the

block in any doc is caught. Also parse `abstract class` in blockSymbol (matches
sourceDeclaration's class support).

persistence.md listed the SessionPersistence surface as create/append/load/list;

descriptions that reference the PR / stack position that introduced the code
("(PR D's teardown)", "Tests for … (PR C)", "identity no longer matters"). The
reader of the current tree has no PR D or prior design to anchor against. Add an
explicit clause: never name the unseeable change unit in a comment, JSDoc, or
test name — state the mechanism instead.

1bb201365d docs(agents): add doc-current-state convention + sharpen the summary worked example (review)
Two review findings on the AGENTS.md additions:

- Add a convention to § Type Safety and Documentation: document the CURRENT
  state (what + why), never the PROCESS/HISTORY of how the code got there. No
  "previously/now/used-to/replaces/the old X" in comments or JSDoc — that rots
  on the next change and belongs in the commit message / PR / RFC. A standing
  contrast against a live alternative is fine; a contrast against the codebase's
  past is not.

- The "tests document behavior" worked example overstated the audit as "nothing
  in production read or wrote" the summary. The backends DID write it (JSONL
  sidecar, SQLite updated_at); what made it dead was no CONSUMER and no
  update() caller. Corrected so a future reader does not infer the write path
  never existed.

815bac7de9 refactor(session): drop the dead mutable SessionSummary
SessionSummary (updatedAt/title/firstPrompt) and SessionPersistence.update()
were dead state: zero production callers of update(), no production reader of
updatedAt/firstPrompt, and ACP's title comes from a tool-call presenter, not
storage. The live Session.header was already typed SessionHeader, so the
summary only ever existed in the persistence layer, written and read by nothing
but its own contract test.

Delete it entirely (no SessionMeta alias — SessionMeta collapses to
SessionHeader everywhere). This removes the JSONL .summary.json sidecar
machinery, the SQLite title/first_prompt/updated_at columns and per-append
updated_at bump, and the update() method from the abstract service and both
backends. SQLite SCHEMA_VERSION goes 1->2 and openDatabase now rejects any
non-current user_version (older or newer) — no migration, unreleased software.

Net -400 lines, and it erases the JSONL-sidecar-vs-SQLite-column durability
divergence that the upcoming write coordinator would otherwise have to model.

Records the decision in docs/rfc/implemented/2026-06-19-drop-mutable-session-summary.md
and migrates the 2026-06-14 session-persistence RFC's facts to current truth.
Adds a standalone AGENTS.md section "Tests document behavior, not golden truth"
(a passing test pins current behavior, not necessarily correct behavior) with
the summary-drop as its worked example, and reinforces the no-migration
pre-release stance.

072f97c184 refactor(examples): extract reusable logic into tested packages
Logic that lived under examples/ was outside the per-file 100% coverage
gate (examples/ are not workspaces) and, in the stdio-UI case, duplicated
across two examples. Move it into packages/ so it is gated and de-duped.

- packages/ui-stdio (new): unify the two diverged stdio-chat.ts copies into
  one @deepseek-ai/dsh-ui-stdio plugin (welcome/agent Config). A test-only
  I/O seam (createStdioChat(ctx, config, runtime)) keeps process streams out
  of the serializable config and makes every render/EOF/disposal branch
  unit-testable. Per-file 100%. echo/coding cordis.yml now load the package;
  both src/stdio-chat.ts deleted.
- packages/llm-replay (new): move examples/acp-agent/src/llm-replay.ts (+ its
  spec) here so its derive/parse/replay branches fall under the coverage gate.
  cordis.snapshot.yml + README rewired to the package name; added apply/env
  /assertNever/abort tests to reach per-file 100%.
- examples/{echo,coding}-agent: keyless Loader-path e2e smokes that boot the
  real cordis.yml (no key) — the guard a hand-mounted unit test cannot be for
  the unwrapExports/export-shape class (postmortem 0001). examples/AGENTS.md
  codifies the keyless+with-key smoke convention (keyless-by-nature exception
  for echo-agent).
- AGENTS.md: a scoped, removal-triggered pre-release stance (foundation over
  blast radius). packages/README.md: new rows + a FIXME to later regroup ALL
  packages into a hierarchy. Wiring: tsconfig paths/refs, publint, knip,
  module-graph.

Verified: typecheck, lint, test:coverage (887 tests, 100%), build, hygiene,
doc-sync, test:snapshot (10), test:e2e (6 keyless pass, with-key self-skip).

224c6f029a refactor(agent-loop): rename LoopAgent to ReactLoopAgent
Rename the concrete Agent class to make its ReAct-style reasoning loop
explicit in the name. Package name, default-export plugin (`AgentLoop`),
and the `ctx.agentLoop` service key are unchanged.

679aaacfc4 refactor(examples): DRY the acp-agent configs via base-core.yml + acp-tail.yml
The snapshot replay config duplicated most of base.yml + the acp tail just to
swap llm-deepseek → llm-replay. Factor the shared pieces:

- examples/base-core.yml: the providerless provider/tool core (llm, sessions,
  system-prompt, tools, agents, invariants, bash-local, tool-bash). base.yml is
  now base-core + the llm-deepseek adapter; the snapshot replay config is
  base-core + llm-replay. The replay config no longer hand-copies the core.
- examples/acp-agent/acp-tail.yml: agent-loop (no pre-created agents) +
  persistence + the ACP bridge/system-prompt, shared by cordis.yml and the
  replay config so the three acp-agent configs can't drift. Its persistence root
  is `$DSH_SNAPSHOT_SESSIONS_ROOT ?? ./.sessions`.
- Deleted cordis.snapshot-record.yml: recording now reuses the normal cordis.yml
  (real adapter), with the harness redirecting the persistence root via env.
  start.ts maps DSH_SNAPSHOT=record → cordis.yml.

Verified: snapshot replay 8/8 keyless; record path works through cordis.yml;
ACP e2e no-key boot green through the doubly-nested include (cordis.yml →
base.yml → base-core.yml); coding-agent boots clean; all gates pass.

b3caabb05d docs: fix snapshot-filter syntax (no --, which vitest reads as a file filter)
`pnpm run test:snapshot -- -t <name>` silently runs ALL scenarios: pnpm
forwards `--` literally and vitest treats everything after it as positional
filename filters, so `-t` is ignored. The working form drops the separator —
`pnpm run test:snapshot -t <name>` (and `-u` likewise).

f09cc81c03 docs: require a snapshot test for transcript/UX-affecting changes
Documents the snapshot tier and makes its use a convention. AGENTS.md gains the
test:snapshot / test:snapshot:record commands (and corrects the now-stale
`pnpm run test` include comment — the unit suite picks up examples/*/tests too),
plus a Conventions bullet: a change affecting the editor-facing transcript or
end-to-end agent UX needs a snapshot test (or an explicit note why none
applies); a pure internal refactor is exempt. The dsh-code-review skill gains a
matching reviewer-only check — review the golden diff itself, since a changed
*.golden is a behavior change in disguise.

8acafe918f feat(acp): show the command in execute titles; test via the real bash tool; RFC for terminal rendering
- bash presentCall title is now "description — command" (e.g. "List files in
  src — ls -la src"). An execute-kind ACP card HIDES rawInput (Zed renders it
  only for non-terminal tools), so the command must ride in the always-visible
  title to be seen — matching how claude-agent-acp/codex-acp title execute
  tools. The command stays in rawInput too for non-execute UIs that show it.
- Rework the acp tool-call presentation tests (turns + load replay) to drive the
  REAL dsh-tool-bash + dsh-bash-local via a new makeBridgeHarness({ withBash })
  option, running an actual `echo` — instead of an inline fake bash tool. The
  mock MODEL still scripts the call (deterministic, no key), but the tool and
  executor are real, so the test verifies the shipping presentCall/presentResult.
- AGENTS.md: add the principle "prefer the REAL implementation over a mock/
  stand-in in tests" (mock only the expensive/non-deterministic boundary).
- RFC (proposed): the ACP terminal sub-protocol + command classification — the
  capability-gated rich rendering (live cwd-header terminal card, classify a
  `cat` as a read / `grep` as a search) that the reference adapters do; the
  fenced ```console text block stays the no-capability baseline. Studied
  codex-acp, claude-agent-acp, and Zed's renderer to ground it.

6d37b6c33d fix(acp): server crashed on connect — drop export default, read optional service cwd-independently
Two independent bugs made the ACP server crash the moment an editor (Zed)
connected, despite 178 green unit tests at 100% coverage:

1. `session/new` threw `cannot get property "agents" without inject`. Root
   cause: a stray `export default apply` made the cordis Loader's
   `unwrapExports` (`exports.default ?? exports`) collapse the module to the
   bare `apply` function, discarding the sibling `inject`/`name`/`Config`
   named exports. The plugin fiber was built with empty `inject`, so every
   `ctx.<service>` read in `apply` threw at load. Fix: remove the default
   export so the Loader uses the namespace.

2. `session/load` threw `cannot get property "sessionPersistence" without
   inject`. `AgentLoop.resume` read `this.ctx.sessionPersistence` (a service
   it deliberately does NOT inject); the property proxy's ancestor-only fiber
   walk fails through the bridge's traceable shadow. Fix: read it via
   `this.ctx.get('sessionPersistence', false)`, the topology-independent
   global-store lookup.

Why the suite missed both: every test mounted the plugin by hand
(`ctx.plugin({name,inject,apply})`), bypassing `unwrapExports` entirely, and
the only test driving these RPCs was key-gated (skipped in CI). Added a no-key
`session/new` e2e that boots the real example through the real Loader — it
fails loudly on bug #1 without an API key. Set `TSX_TSCONFIG_PATH` in the e2e
spawn so the subprocess resolves workspace `paths` from a temp cwd (it was
silently falling back to a stale built `lib/`).

Docs: post-mortem 0001; AGENTS.md "line coverage is not behavior coverage" +
with-key/smoke-test philosophy; packages/AGENTS.md plugin-export-shape and
ctx.get rules; dsh-code-review SKILL checks.

7c400e9c02 docs: unify ADR/RFC trees into one lifecycle-organized RFC tree
Collapse docs/adr/ and docs/rfc/ into a single docs/rfc/ with proposed/,
implemented/, and rejected/ subfolders. Every file is renamed to
yyyy-mm-dd-topic-title.md, where the date is when the topic was first
proposed (from git history). ADRs and RFCs that covered exactly the same
topic are merged (property-based testing, session persistence); the
umbrella RFC 005 stays split across its three implemented decisions, and
RFC 006's deferred part-3 (API extractor reports) splits into its own
proposed RFC. All cross-references become machine-checkable relative
links instead of bare "ADR NNNN" / "RFC NNN" prose.

Add a verify-md-links doc-sync gate (scripts/verify-md-links.ts) that
checks every relative Markdown cross-link resolves, wired into doc-sync
alongside verify-md-wrap. This makes the reorganization self-verifying:
the same change that rewrote ~forty inter-doc links adds the check that
proves none dangle. Document the cross-link convention in a new
docs/AGENTS.md and record the gate as an implemented RFC.

doc-sync, typecheck, lint, and the full test suite (667) all pass.
