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.
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).
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.
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.
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.
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.
ds-review-bot findings: the packaged Python runtime smoke's scripted
run_code call gains the required description; the ToolDefinition JSDoc
and the Code Mode foundation note (both languages, pair re-recorded) now
state both required parameters; the cordis-dynamic-toolchain fixture's
request/header line is re-compacted so the header-scrub hygiene guard
passes (my earlier patch had re-spaced it). The TUI terminal fixture was
already regenerated from keyless replay in the previous commit.
One highlighter for the client: a synchronous fine-grained shiki core
(JS regex engine, no WASM) in ui-primitives with an explicit grammar
allowlist (typescript, shellscript, json — aliases resolve, unknown
languages take a geometry-identical plain arm). The shared CodeBlock
component owns both arms; markdown fences, the run_code expanded
program body (typescript), and the details panel Input (json) all
route through it. Token colors live in a new ui-theme shiki.css sheet
as --shiki-* custom properties (light/dark blocks), wired through the
shell's base.css chain — tokens-only styling holds; shiki's generated
span tree is the sanctioned innerHTML path (static output, no user
HTML). jsdom specs pin token spans, aliases, both fallbacks, and the
fence route; the built-bundle snapshot asserts the highlighted program
under the code row.
New tools/code-dispatch-log waterfall (run via registry.shapeDispatchLog,
contained — a throwing listener falls back to the unshaped content) lets
listeners reshape the tool/code-dispatch event's content before the
bridge appends it. dsh-spill-policy registers a second arm sharing the
model-facing arm's exact replacement pipeline (same maxInlineBytes cap,
preview + locator, within-cap invariant, best-effort fallbacks), with
artifacts labeled dispatch under the sub-call id. The program's value is
untouched; read sub-calls ARE bounded (a log copy is not model context,
and read produces the biggest logs). Resolves the tools README's
uncapped-dispatch-log Known Limitation.
Review finding (Codex round 1): abstract erases at runtime and
@deepseek-ai/dsh-tasks used to be the mountable registry, so a stale
composition row would register a ctx.tasks with no method implementations
and fail far from the misconfiguration. The seam constructor now rejects
direct mounts with a load-time pointer at dsh-tasks-local; the seam suite
pins the fence, the Agent Note cost paragraph records the actual behavior,
and the stale tool-pty README requirement line names the implementation
package.
One tiny recorded text turn drives three whole-page concerns:
- workspace flow over the real wire: the empty-state hero's first send
materializes a real Workspace + Session (the jsdom workspace-flow suite
pins this state machine over the fixture client; this scenario pins it
through HTTP RPC + SSE + the gateway). Durable proof: the session
header's cwd is the create-by-name target <workspaceRoot>/workspace.
Adds the hero waiting-state aria golden.
- reload recovery: collapse the sidebar (persisted dsh.layout.panels),
page.reload, and the surface comes back whole from persistence alone —
layout collapsed, selection restored (dsh.sessions.current), the
recorded turn re-rendered from session.history with zero model calls
(the drained replay cursor makes any stray request fail loud at close).
- dark mode: no product control flips the theme yet, so the scenario
drives the ThemeService's entire DOM contract — body[data-ds-dark-theme]
— and pins the shipped cascade: the alias token flips, a painted surface
repaints, and removing the attribute restores the light sample exactly.
TODO(web-theme-gesture) upgrades to a real settings control; no theme
golden per the lane's scope ruling (aria is color-blind).
Agent Note scenario list extended in both languages; pairing re-recorded.
The bridge replaces its serialization queue with a pool that reuses the
native concurrency contract: submissions classify through
registry.executionMode (fail-closed isConcurrencySafe), start strictly in
submission order, overlap up to the validated maxParallelSubCalls config
(default 10; 1 restores serial), and exclusive calls drain the pool, run
alone, and bar later calls. Each started sub-call logs a
tool/code-dispatch-start event at pool entry; the existing
tool/code-dispatch settles the pair (started ⇔ settles exactly once;
abandoned queued calls log neither). SDK prompt guidance now states the
true Promise.all contract — re-recorded across every code/both-mode
snapshot (plus the stale cordis-dynamic-toolchain fixture gaining the
required description arg).
Client: CodeSubCall widens to RunningToolCall | ToolResultNode — starts
land the running shape (rows wear the native running ring), settles
replace in place preserving start order, callTime pairs to the start
time. Fixture emits start/settle pairs; jsdom pins the running sub-row;
runtime specs pin in-place settlement and out-of-order completion.
Review round on the pivoted design:
- node-24 (static) kept an unconditional hosted pnpm cache restore while the
coverage and consumers lanes skip it under failover. On the self-hosted VM
that restore downloads ~180 MB into /home/runner, a path pnpm never reads
there, adding latency and contention during an outage. Gate it with the same
`vars.DSH_CI_FAILOVER != 'selfhosted'` condition so all three lanes match.
- Runbook switch step 2 said "Re-run failed jobs", but the documented
indefinite-queue outage leaves jobs queued (not failed), which cannot be
re-run in place and do not retarget on variable change. Correct both language
sides to cancel the run and re-run all jobs, or push a new commit.
- The standby-lane comment still described the switch as a one-line runs-on
change; it is now setting the admin-only DSH_CI_FAILOVER variable.
Adds the Chinese counterpart of the new seam note, records both pairs
(new note + the updated background-task runtime note), and ratchets the
translation-pairing manifest.
The failover runbook landed as .agents/notes/implemented/process/ci-failover-runbook.md,
which fails three doc-sync gates: the classification/format gates require a
yyyy-mm-dd-topic.md filename and the implemented Agent Note skeleton
(Problem/Decision/Alternatives/Consequences), and the bilingual pairing gate
requires cross-note link targets to match between the two language sides.
Rename to 2026-07-26-ci-failover-runbook.md/.zh.md, reshape both sides into the
implemented skeleton (the runbook steps live in bespoke sections under Decision),
point the sibling topology note and the ci.yml comment at the dated filename, and
make both sides link the canonical .md per the bilingual convention. Re-recorded
the i18n pairing records.
One two-turn seed (turn 1: bash + two parallel reads in a single assistant
message; turn 2: a markdown-heavy reply) rendered cold through the
seeded-history pattern — zero model calls — serving four surfaces:
- sidebar search: client-side title filter; asserted only after the durable
title lands with the attach baseline (a cold SessionSummary carries no
title — search matches the displayTitle the user sees). Negative query
empties the tree, positive narrows to the match + its force-expanded
group, clear restores.
- Trajectory tab: turn sections, the step group's tool mix ('bash read×2'),
and a view-area aria golden.
- Waterfall tab: span stats header + one lane per span. The P-I fold counts
a turn-0 prologue span (only assistant/steering nodes carry a turn
number) — pinned as-is; real spans are P-III per the view's ledger.
- details column: the bash toolview row routes click to openDetails;
open/closed is asserted on the frame's data-details-collapsed attribute
because close collapses the grid column to width 0 without unmounting
the subtree (hidden, not absent, is the contract).
Agent Note scenario list extended in both languages; pairing re-recorded.
The tasks/ family now matches the capability-seam shape: @deepseek-ai/dsh-tasks
keeps the abstract TaskService (ctx.tasks contract, vocabulary types, snapshot
invariant companion) and the new @deepseek-ai/dsh-tasks-local carries the
process-local registry (LocalTaskService: in-memory store, settlement,
owner-cleanup effects, teardown, TASK_WAIT_TIMEOUT). Compositions and test
harnesses now load dsh-tasks-local; producers, TaskKindMap merges, and
dsh-tool-tasks keep importing the seam only.
Producer misconfiguration diagnostics name dsh-tasks-local because loading the
implementation is the fix. The registry behavior suite moves to tasks-local;
the seam keeps a stub-subclass registration test and the probe-based invariant
suite.
