Round 1 of Codex review on the extraction PR.
- (B) EOF-exit race: the 200ms flush-then-exit setTimeout was untracked, so a
fiber/HMR dispose within that window could not cancel it and the process
would still exit. Track the handle and clear it in the disposer; coalesce
re-entrant maybeExit() calls onto the one pending timer. Regression tests for
both (dispose-within-window cancels; repeated idle schedules once).
- (B/doc) ui-stdio rendering is global, not scoped by config.agent (faithful to
the original copies — agent scopes only input + the EOF-exit gate). Corrected
the README + Config JSDoc, which overclaimed "drive and render".
- (C) createStdioChat is exported and driven directly by tests/programmatic
callers that bypass schemastery validation, so default welcome/agent in the
helper (?? 'ready.'/'main') instead of trusting the cast. Test for empty config.
- (A/doc) docs/rfc/.../acp-snapshot-tests.md asserted the replay plugin
deliberately stays in examples/ ("don't split preemptively") — now false since
this PR packages it. Added a superseding note with the why (coverage gate).
All gates green: typecheck, lint, test:coverage (891, 100%), doc-sync,
test:e2e (6 keyless pass), test:snapshot unaffected.
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).
