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).
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.
Conflict resolution: session.ts keeps this branch's paired-start callTime
(the start event exists here; a settle-only window stays null — the PR2
fix's semantics compose). The README's codeDispatches section is restored
to the running→settled lifecycle this branch implements, keeping PR2's
null-callTime nuance for starts outside the window.
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).
agent-loop: behavior tests for retry-while-busy, cancelled recovery
windows, no-facts stream failures, idle-listener preemption, rejected
driver promises under whenIdle, finish-chunk failures after step close,
presentationMeta persistence, pre-aborted and torn-down create/resume
signals, and configured-start failures over existing artifacts or after
teardown. The remaining guards that no public path can reach carry
justified v8 ignore annotations naming the invariant that starves them.
acp bridge: cover the retry-adoption path (a retry turn resolves the
prompt the failed turn deferred), the no-retry quiescence rejection, and
the admission-blocked cancelled settlement; the synchronous send-throw
catch is annotated as a future-proofing guard since the machine's send()
contains listener failures.
Responding to ds-review-bot round 2 on #653: the tool/code-dispatch event
is appended at settlement, so using its time as callTime fabricated a
zero-duration call for duration-aware consumers — it is now null (start
unknown) per the ToolResultNode contract, pinned in the session spec. The
README's codeDispatches section described the PR3 running→settled
lifecycle a stack ahead of this tree; it now documents the settled-only
index this PR ships (the running shape lands with the start event in
#658, which already merges cleanly over this).
Responding to ds-review-bot round 2 on #648: the env seam's accepted
values, native default, process-wide scope, loud-failure behavior, and
temporary status now live in apps/cli/README.md next to the Web/headless
surface it configures, not only in the cordis.yml comment.
CI coverage flagged MarkdownText's pre route: the array-element probe
(raw[0]) and the mixed-content fallbacks were unreachable — the markdown
pipeline hands pre one code element whose children are one string (or
none, for an empty fence). Simplify to the string check, annotate the
isValidElement guard as representation-change armor, and pin both live
arms: the empty fence keeps the stock <pre>, a language-less fence renders
the plain CodeBlock arm.
The websettings merge (#644) localized the sidebar foot to 设置; the
lifecycle-chrome hero golden pinned the old English label. Keyless
DSH_SNAPSHOT=refresh rewrite; full lane green twice after.
CI's full-tree coverage flagged three untaken paths this PR introduced:
- shapeDispatchLog's catch (a throwing tools/code-dispatch-log listener
must be contained — the settle event logs the unshaped content);
- the spill listener's flatten-decline arm (non-text sub-result content
passes through unchanged);
- the generated scope-key extractor row for tools/code-dispatch-log
(registered in the scope invariant matrix like the other tools events).
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.
Both ds-review-bot findings were real:
- markLlmAdapterFailure's carried-facts cross-check read error.code
directly; a foreign Error with a valid own failure payload but a
throwing code accessor would replace the original adapter error with
the accessor exception, breaking the error-identity guarantee. The
read now goes through foreignErrorCode(), which contains the trap and
falls back to the normalized snapshot (test: hostile code accessor
beside a valid failure payload -> original identity kept, UNKNOWN
facts).
- live-interactions' afterEach caught scaffold.close() into undefined,
silently disabling ReplayHandle.assertConsumed() — the fixture-drift
tripwire — and hiding cleanup defects. Teardown now runs every step,
collects failures, and rethrows (AggregateError when several).
Responding to ds-review-bot on #664 (root cause lives here): when a history
window carries a tool/code-dispatch settle without its paired start, the
runtime fabricated callTime = settle time, so downstream duration views
presented a measured 0 ms. Match the native tool-result contract instead —
callTime: null = unknown — and pin it; the trajectory cell already renders
null as the em dash, and the waterfall gains explicit unknown handling in
its own PR.
The static CI gates run per-branch on the merged tree: the cordis
catalog/api, config-catalog, and type-equiv manifest updates for the
tools/code-dispatch-log waterfall and CodeDispatchLog payload previously
landed only on the shiki branch (09734f23b); this branch's own tree needs
the same regenerated outputs and manifest entries.
The coverage gate flagged three untaken paths in the bridge scheduler:
- the exclusive-head inFlight re-check was dead (the shared guard above
already returns for an exclusive head with any in-flight sibling) — removed;
- the commit-cursor undefined-dispatched break was structurally unreachable
once entries join commitQueue only after start() ran synchronously —
reordered the pump so the invariant holds by construction, annotated;
- the finish (final-result) commit arm and the pump re-entry guard gain a
covering test (throwing tools/pre-execute listener) and a defensive
annotation respectively; mid-run unregistration test renamed to match its
actual post-result settlement path.
Also covers the direct-construction maxParallelSubCalls default (index.ts)
and commits the regenerated persistence catalog for the new dispatch pair.
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.
