The rebase onto master picked up #585 (agent-loop message machine), which
removed the request-only session-prefix seam; the unified sourced-message
decision now owns the mechanism and the note's own banner declares the
seam removed. Archive the triplet and rewrite the skill-system note's
catalog mechanism against the shipped agent/step sourced injection,
keeping the archived note as the intentional historical citation.
Re-checked the other notes master added or amended (provider retry
policies, request-error retry action, observable state machine, OTel
telemetry, dependabot): their supersessions were already executed
upstream in the same PRs; no further active note qualifies.
Archive 21 implemented triplets whose shipped decisions are complete and
whose bodies no longer guide future work (one-off UI chrome, generator
applications whose scripts are self-explanatory, superseded implementation
detail, process history owned by current contracts/skills). Delete 4
rejected triplets whose premises are obsolete: the DeepReadonly proposal
(dev-invariants note now carries the alternative inline), the collapse
tool-owned presentation proposal (superseded by the shipped render-intent
union), retire-mid-turn-steering (steering is now load-bearing across
plan-mode/apiproxy/TUI), and single-session-ACP (automation-only ACP
resolved the question; multi-session isolation is pinned by tests).
Repair every inbound link: retarget intentional historical citations to
archived paths, replace decision-current citations with the surviving
authority, and fix the stale example-execute-over-tsx pointer in
pnpm-workspace.yaml. Re-record pairing sidecars and seal the archive
manifest (append-only; existing seals unchanged).
The group's convention is package suffix == provider default
(subagent-acp/'acp', subagent-spawn/'spawn', subagent-fork/'fork'), and the
provider default became dsh-sdk in the last review round — so the package
follows: @deepseek-ai/dsh-subagent-dsh-sdk at
packages/subagent/subagent-dsh-sdk, plugin name subagent-dsh-sdk,
diagnostics prefixed subagent-dsh-sdk:. The dsh echo has precedent
(dsh-llm-deepseek). Directory, fixture path, knip/tsconfig/examples
registrations, catalogs, READMEs (en+zh), and the Agent Note follow; the
sdk-client dispose ladder moves to its own module (src/dispose.ts) with the
deterministic FakeChild tier tests restored alongside it.
Master's #660 replaced dsh-subagent-subprocess with the dsh-subprocess
capability seam (ctx.subprocess + scrubbedParentEnv, tree-scoped teardown)
and moved subagent-acp onto it. Convergence for this branch's packages:
- The shared out-of-process provider vocabulary this branch had grown in
the deleted library (NO_START_CAPABILITIES, assertPositiveFinite, cwd
resolution, settleRunResult, subprocessRunHandle) moves into the subagent
seam package as out-of-process.ts — it enforces subagent-seam contracts,
not process mechanics, and both out-of-process backends now import it
from there (subagent-acp keeps master's shape otherwise).
- subagent-sdk spawns THROUGH the SDK client (the subprocess README's
documented exception for SDK-managed transports) and now applies the
seam's scrubbedParentEnv() + explicit-env merge in place of the deleted
buildChildEnv.
- sdk-client inlines the EOF→SIGTERM→SIGKILL ladder as private helpers (it
runs outside any harness context, so it cannot ride ctx.subprocess).
- The child harness fixture gains the now-required dsh-subprocess-local
entry for bash-local; the fixture cordis.yml keeps exercising the
shipped provider default.
Resolutions: regenerate the conflicted generated docs (cordis services
catalog, event-producer-consumer, module-graph); take master's
packages/README pair and re-insert the telemetry row on both sides;
re-record the README and session-doc translation pairs.
