The automation-only ACP refactor (#586) removed the bridge's pendingSwitches
idle-preset anchoring the inheritance note cited as precedent. Replace the
dangling analogy with the load-bearing fact a reviewer actually needs: an
injection-triggered first turn (a SessionStart hook racing the prompt)
dispatches no prompt-submit and no model request, so the one-shot stamp
listener still lands before the child's first model request.
A repo-wide Not Invented Here audit (ten parallel domain surveys covering
every package group, scripts/, native/, vendor/ edges, python/, test
infrastructure, and CI) asked of each hand-rolled surface whether a
maintained external package or Node builtin deletes it with a net win.
Policy: new implemented process note records that a dependency which
genuinely deletes owned code is a preferred simplification (bar: net
deletion, health, boundary fit, settled seams stay); root AGENTS.md
carries the one-line rule and dsh-find-simplifications now surveys for
hand-rolled-where-a-dependency-exists candidates.
Findings, all bilingual from birth:
- proposed/simplification: eventsource-parser for llm-deepseek SSE,
node:timers/promises for three hand-rolled sleeps, turndown (or
minimal 'entities') for tool-web HTML->markdown, gate-script
consolidation onto mdast/parseArgs/globSync
- proposed/testing: execa + parseArgs + loadEnvFile + vi.waitFor for
hand-rolled test subprocess plumbing
- proposed/process: pnpm/action-setup for symmetric CI caching
- proposed/feature: evaluate landstrip before building a Windows
sandbox launcher
- rejected/simplification: ~30 swap verdicts recorded (vscode-jsonrpc,
p-retry, Ajv, write-file-atomic, msw, hono, better-sqlite3, wireit,
landstrip-for-linux, YAML consolidation, ...) so the survey is not
re-litigated from scratch
Also drops the stale prompt/ entry from the AGENTS.md layout map
(workspace instructions live in packages/context/workspace-context).
Adds the zh counterpart, aligns the seam note's zh side with its updated
interface bullet and follow-up sentence, records both pairs, and ratchets
the translation-pairing manifest.
Conflict resolution: drainDispatches composes both sides — the reworked
single-lane driver's drive() (ordered stages, mid-flight commit drain)
followed by this branch's logWork drain, so every shaped settle append
still lands inside the open run_code turn.
Review direction (tianyicui, PR #660): in a stacked PR, change all other
process-running places to use the new service.
- lsp-local: LspConnection spawns through ctx.subprocess (piped protocol
streams + a no-spill collected stderr tail); its private process-tree
helpers (POSIX group signalling, Windows taskkill, liveness polling) are
deleted in favor of the seam's handle verbs, and its buildChildEnv now
rides scrubbedParentEnv (LSP children also stop inheriting stale DSH_*).
The plugin injects 'subprocess'; compositions/tests mount
dsh-subprocess-local.
- subagent-acp: the ACP child spawns through the seam (piped ndjson streams,
inherited stderr); spawn failure surfaces through done-rejection into the
same startup race; disposal is handle.dispose with the plugin's configured
graces. dsh-subagent-subprocess is DELETED — its dispose ladder and scrub
are the seam's, and the isolated-config-dir helper had no consumer.
- mcp-client, pty-local, sdk-helper: adopt scrubbedParentEnv as the one
scrub definition (their spawns stay put by ownership: the MCP SDK and
node-pty own those calls; the SDK wizard runs outside any composition).
- Coverage: per-file 100% over every touched src file, with each v8 ignore
carrying a platform or contract reason; new suites cover stdio
dispositions, the dispose ladder tiers, injected-win32 tree semantics,
waitForExit, settled-kill/terminate no-ops, and spawn-failure disposal.
- Docs: consumer-migration Agent Note (en; zh follows in this PR), seam note
updated in place, subprocess.md rewritten for the reshaped vocabulary
(type-equiv re-registered), READMEs and SERVICE_ROLES updated, taskkill
added to knip ignoreBinaries.
Responding to ds-review-bot round 2 on #658 (three critical findings, one
warning — all rooted in the pump/commit split racing ordered stages):
- ONE driver lane now owns every ordered stage: the start append, prepare
(pre-execute/guards), and the head-of-line commit (post-execute, context
deferral, settle append). start() is awaited before the next entry can
start, so concurrent submissions can no longer run pre-execute pipelines
concurrently; only the around-dispatch/body stage overlaps, matching the
native loop's fillPool sequencing.
- An exclusive call's barrier now holds through its COMMIT: later starts
wait for the exclusive pipeline (post-execute included) to finish, the
native exclusive-group semantics.
- drainDispatches() awaits the driver run itself, so a commit already
mid-flight when the program returns is drained before run_code closes
the turn — the settle event and deferred contexts land inside it.
- maxParallelSubCalls is resolved and validated at construction (positive
integer), so direct construction can no longer wedge the pool with 0.
New tests: overlapping-submission ordered-prepare, barrier-through-commit,
drain-mid-commit, cap rejection. 96 keyless snapshots replay unchanged;
Agent Note updated (both languages).
The automation bridge inherited two master-era assumptions the message
machine no longer honors. A prompt blocked at pre-turn admission opens no
turn, so no turn/end could ever settle it — the bridge now watches
whenIdle() and reports a turnless slot as cancelled (the disposed-agent
guard moved to a registry identity check before send). A failed turn no
longer rejects at its turn/end either: agent.retry() closes the failed
turn and opens a successor on the same history, so the bridge holds the
terminal error and lets a retry-triggered turn/start adopt the prompt,
rejecting only at quiescence with no successor.
Also: refresh the empty-response-retry fixture for retry-as-turn logging,
adapt master-side tests to the unified send()/UserMessageData API and
registry-fact disposal, resync the doc pairs both sides touched, trim
architecture.md back under its word ceiling, and regenerate the event and
persistence catalogs.
Responding to ds-review-bot on #664:
- SubSpanLane gains a 'timing' discriminant (measured | running | unknown).
A settle-only replay entry (callTime null, start outside the window) was
previously indistinguishable from a measured 0 ms span; it now renders
hollow with a 'duration unknown' hover title, and durationMs stays null
for anything unmeasured. Pairs with the client-runtime fix that stopped
fabricating callTime = settle time (826c3696a on the live-parallel PR).
- The built-client Code Mode fixture snapshot now switches to the
Trajectory and Waterfall tabs and pins the assembled rendering: three
Sub cells with real +0.8s durations and three measured lanes with their
hover titles — product-visible coverage through the real bundle graph,
not just package-level jsdom fixtures.
Agent Note (both languages) updated for the timing contract; pairing
re-recorded.
Codex re-review (A): AGENTS.md layout tree, the architecture capability
tables (en+zh), the seam Agent Note's group-name sentence (en+zh), and the
SERVICE_ROLES entry still carried process/-era labels; regenerated the doc
graphs and config catalog from the corrected inputs.
ui-sidebar shell landed on master (#643: geometry-only shell, the
browsing region moved to the sidebar.workspaces slot); this branch's
sidebar.settings foot seat re-applies on top — the hardcoded foot row
becomes the seat, the seat rides the railIn crossfade, and the shell
spec's renderSlot stub key-splits region vs settings.
Every spec now commits at least one golden and the interactive ones one
per distinct end-state (nine new .expected.md):
- live-interactions: cancel.expected.md (frozen partial + 已停止 marker),
error-auth.expected.md (the prompt bubble alone — the committed artifact
of the web-error-surface gap, the diff that flips when error rendering
lands), retry.expected.md (indistinguishable from a clean completion —
retries are deliberately invisible in the transcript).
- question-composer: answered.expected.md (the question resolved into its
tool round trip plus the final reply, takeover gone) beside the existing
waiting-state golden.
- steering: mid-steer.expected.md pins the accepted-but-INVISIBLE state
(the loop drains steering only at the step boundary, so no interjection
bubble exists while the question still blocks — if the client ever
renders pending steers eagerly, this golden flips first) and
settled.expected.md the badged bubble plus obeying reply.
- navigation-panes: waterfall.expected.md and details-open.expected.md
(tool-name header, Input args, Output result) beside the trajectory one.
- lifecycle-chrome: reloaded.expected.md — rendering the same settled
transcript from persistence alone IS the recovery claim.
Fixture inventories extended to the new closed sets; the Agent Note's
expected-outputs policy updated in both languages (per-end-state goldens
for interactive scenarios), pairing re-recorded.
Review feedback (tianyicui): 'process' is a poor service name. The family is
now packages/subprocess/ — @deepseek-ai/dsh-subprocess (ctx.subprocess,
abstract SubprocessService, Subprocess* vocabulary) and
@deepseek-ai/dsh-subprocess-local (LocalSubprocessService) — renamed
throughout code, compositions, docs (en+zh, pairs re-recorded), catalogs,
and gates. 'subprocess' is the precise term for managed OS children (the
Python-stdlib sense), avoids colliding with Node's global process object,
and reads as one system beside dsh-subagent-subprocess.
ds-review-bot findings addressed:
- kill() on a settled handle is now a no-op (no signal to a possibly-reused
pgid, no referenced grace timer delaying exit); pinned by a spy test.
- The moved DshEnvironmentKey/DshEnvironment/CollectedOutput types get
drift-checked type-equiv blocks on the new subprocess.md page, restoring
their manifest registration.
- subprocess.md is registered in the core.md sub-page index (en+zh).
The shell is now a pure composition face: no dictionaries, no locale
dependency, and three new chrome content seats (settings.trigger /
settings.header / settings.close) whose slot content also carries the
accessible names (trigger text, dialog aria-labelledby, visually hidden
close label). ui-settings-general returns as the owner of copy that
belongs to no single feature: chrome content, the General section with
its item slot, and the settings dictionaries. Slot types split homes —
trigger/header/close/section live in the shell contract; the
settings.general.item entry moves to the locale package (the common
dependency of every item registrant), with ui-theme consuming it
through a re-export seam; the verbatim duplicate merges are gone and
the dependency graph is a clean DAG.
Review feedback (tianyicui, PR #657 inline): the missing-service message
should mention dsh-tasks, which defines ctx.tasks, rather than promoting a
specific backend. The seam's own surfaces (README, the direct-mount fence)
keep pointing at implementations, so the pointer chain still lands on
dsh-tasks-local without the producer strings going stale when another
backend becomes the recommended default. Agent Note updated accordingly
(en+zh, re-recorded).
deferRegistration() stays the shipped form; the note pins the follow-up
direction (bridge declarations into slot:<name> services, migrate
registrants to nested ctx.inject, delete the helper) and the boundaries
a separate PR must settle.
The branch edited the English side of 17 doc pairs without their Chinese
counterparts. Bring every .zh.md up to date (loop.ts references now point
at agent.ts, send/steer/inject unification, context/message folded into
user/message, HookContext replaced by UserMessageData in tool decision
blocks, plan/skill delivery moved to agent/step) and re-record the pairing
hashes. Deduplicate type-equiv.manifest.json entries duplicated by the
master merge and drop entries for symbols the refactor removed. Complete
the missing JSDoc on extractSnapshotSpillPaths.
Trajectory: the layout fold interleaves one subtool cell per sub-dispatch
after its parent Tool cell (assistant-block calls, orphan results, and
running calls alike), indexes sequential across the interleave; settled
durations come from the start/settle pair, running sub-calls show the
em dash. New Sub tag (business tint) + 28px indent.
Waterfall: deriveSubSpans folds the dispatch index into per-turn lanes
with REAL wall time — each parent's window is first start → last settle
and every lane's offset/width is its fraction of it, so parallel
sub-calls visibly overlap; running lanes extend to the window end at
reduced opacity. Lanes draw under the owning turn row.
Both views read codeDispatches through the standard snapshot hook; no
new wire data, replay renders identically to live. Specs pin interleave
order, durations, the running arms, window fractions, and the rendered
lane.
