The retained-whenIdle paragraph claimed "live consumers (the ACP bridge's settle
points)", but `packages/ui/acp/src` has no whenIdle() call — the bridge owns its
agents and tears them down via AgentHandle.dispose(). whenIdle()'s live consumers
are ACP and agent TESTS awaiting settlement through the public seam. State that.
The reviewer caught two pieces of both-seams drift left over after the bash
get()/list() removal was reverted to a persistence-only change.
- docs/rfc/README.md: rename the index row from "persistence and bash seams" to
"Prune dead methods from the persistence seam" so it matches the RFC title and
the actually-shipped scope (verify-rfc-classification only checks the path is
indexed, so this prose slipped the gate).
- The implemented RFC body still read like the original both-seams proposal
(the "Two capability seams" framing, a `### BashExecutor.get()/.list()` problem
section, a bash removal bullet in the Proposal, and current-source links that
imply bash get/list were removed). Rewrite the body into the durable
decision-record form: Problem/Proposal/criteria/risks now describe only the
persistence has()/delete() removal that shipped, and the bash reasoning (why
get()/list() earn their keep — a ~35-line test-harness migration cost makes the
test consumer a real consumer) is folded into the top decision note as
"considered and deliberately kept", not as a shipped change. Drop the stale
bash source-line refs; keep the persistence consumer links pointing at current
code (agent-loop load, ACP session/list).
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).
Type-only change (brands are zero-cost casts; no runtime/wire impact). Closes
the two gaps in the "brand ids that cross package boundaries" policy and fixes
the dependency direction so a capability package never pulls in an unrelated one.
- Extract the `Branded<B>` primitive into a new standalone type-only package
`@deepseek-ai/dsh-brand` (packages/util/brand) with no harness-package deps.
dsh-llm keeps its owned CallId but imports Branded from dsh-brand; dsh-session,
dsh-agent, and dsh-bash all import Branded from there. dsh-bash depends on
dsh-brand ALONE — never on dsh-llm or dsh-session (the architectural fix: a
generic execution backend must not couple to the LLM or session vocabulary).
- Mint BashTaskId + OwnerToken in dsh-bash and thread them through BashTask.id,
the get/ownerOf/list/readOutput/kill seam, the bash-local generation site, and
the dsh-tool-bash validate/access surface. OwnerToken is a DISTINCT brand from
SessionId so the seam stays decoupled; dsh-tool-bash is the single boundary
that casts SessionId -> OwnerToken.
- Brand at the SOURCE, not via mid-pipeline casts: agent-loop's Config types
agents[].id as AgentId and resumeSessionId as SessionId, so the brand enters
at the config boundary and the inner create()/resume casts disappear (only the
genuinely-new per-run session-id string is cast).
- Stop brand erosion: propagate CallId/SessionId/AgentId to the registry/store
Map keys and public params/exports (SessionStore, AgentRegistry + factory
options, the ACP session-id surface + ToolPresenter CallId map, the
persistence coordinator, invariants pendingCalls, the pi-ai tool-call maps).
- Docs: document BashTaskId/OwnerToken in bash.md (type-equiv re-pasted), point
the Branded type-equiv at dsh-brand, fix stale param types in the session/
agent/bash READMEs, regenerate the cordis catalog + module graph.

The original prune removed BashExecutor.get()/.list() too, but each is a
one-line accessor over the executor's already-tracked tasks map, and removing
them forced dsh-tool-bash's tests onto a ~35-line onTaskDone completion-tracking
harness just to replace the one-line ctx.bash.get(id) lookup. Per the AGENTS.md
"RFCs are proposals, not golden truth" principle, that disproportionate
migration cost is evidence the methods earn their keep — a test harness IS a
consumer programming against the seam.
Restore get()/list() (seam + LocalBashExecutor impl + the bash tests that used
them, dropping the doneFor/trackCompletions scaffolding). The persistence
has()/delete()/deleteStored removal stands — it had only contract-test callers
and no test-ergonomics cost. The RFC is retitled persistence-only with an
implementation note recording the bash revert.
Two capability seams carried abstract methods no production consumer calls.
A method no consumer programs against is not a seam — it is speculative
surface every implementation must still provide and test.
- SessionPersistence: remove has() and delete(), the coordinator's
has/delete/deleteCore, and the PersistenceBackend.deleteStored hook (with its
jsonl + sqlite + in-spec memory-stub impls). Surviving service surface:
create/append/load/list. Production uses only load() (resume) and list()
(ACP session/list).
- BashExecutor: remove get(id) and list(), the abstract decls and the
LocalBashExecutor impls. The internal tasks map survives (it backs
ownerOf/readOutput/kill); get/list were pure public accessors over it with no
shipping caller and no bash_list tool.
- Migrate tests that reached through ctx.bash.get(id) to the public completion
seam: a doneFor(id) helper over onTaskDone awaits a task by id, and the
HMR-reload ownership test now proves task survival through A's own bash_output
([status: running]) plus ownerOf + B-rejection — a stronger through-the-tool
assertion than the removed lookup peek.
- Update seam READMEs (six -> four service methods, drop the deleteStored hook
and the get/list row) and the two implemented persistence RFCs in place.

Codex review of the PR1 diff surfaced docs/cleanup drift:
- LlmService class JSDoc still advertised "streaming / non-streaming call
surfaces, both interceptable via waterfall events" — corrected to the single
streaming surface; regenerated the cordis catalog so its mirror updates.
- Removed GenerateResult from gen-cordis-catalog.ts LINK_MAP (the type is gone).
- The adapter-change RFC's acceptance criterion named the retired
verify-event-taxonomy gate; updated to verify-cordis-catalog.
- Dropped the now-tautological "streaming and one-shot assembly agree" property
test (the streaming/one-shot distinction lived in the removed flush API;
usage/finish remain covered by assembler.spec.ts and the finish property).
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

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.
