Part of the file-write-safety series (#1375) — B2: per-task change journal. Stacked on #1404 (B1, per-write checkpoints).
What
Append-only changes.jsonl under the task's checkpoint dir — one entry per successful file write: path, operation, checkpointId (the B1 checkpoint id), and diffStats (additions/deletions from the already-computed approval diff where available).
Torn-tail repair on load — a crash mid-append leaves a truncated final line; loading discards it, parses the rest, and never throws, so the journal survives a crash with no corrupt load.
Gated by perWriteCheckpoints — the B1 master switch: off = no journal entries, writes behave exactly as today.
Tests
changeJournal.spec.ts — append format (one JSON line per entry), clean-tail load, torn-tail repair (truncated final line discarded, rest parsed, no throw), absent/empty journal → [].
Hook-level: a successful write through the B1 hook appends exactly one journal line referencing the B1 checkpoint id; with the setting off no line is appended.
Regression: the B1 suites (write/edit/applyPatch hooks, Task, ClineProvider) stay green.
Local gates: eslint 0, tsc 0, 100% patch coverage.
Hardening (post-review)
Partial flush on mid-patch failure — when a later hunk is rejected (a .rooignore access denial), the loop breaks instead of returning, so writes completed by earlier hunks still receive the B1 checkpoint, the journal entry, and the change card; the failed patch also keeps the consecutive-mistake counter from resetting.
Failed-move journaling — if a move's destination file is written but the source deletion fails, the move is reported as a failed tool error while the destination write is still journaled and checkpointed, so that state stays restorable.
Regression tests: "checkpoints the written subset when a later hunk is access-denied" and the updated failed-move test (the checkpoint covers exactly the destination write).
Content source of record
kind: branch - feat/change-journal-b2, refreshed onto current main by merge 1d2373d80 (upstream/main 9c069e94ef); formatting-only follow-up 86f41828b.
Budget (own delta at this head)
Own delta vs the B1 head (b01a334e4): 11 files, +1026 / -70. The GitHub stacked view is larger until B1 merges; merge order: B1 (PR 1404) first.
Expected: all green; src/eslint-suppressions.json unchanged.
Verification at this head (25fe557a8)
CI: 19/19 checks green at head (incl. compile with the new format:check step).
Local: ESLint --max-warnings=0 clean on all 14 touched src files; tsc --noEmit clean; src vitest 500 passed / 5 skipped / 0 failed (7 files); webview-ui vitest 27 passed (2 files); post-format re-run of the four reformatted spec files: 88 passed / 5 skipped / 0 failed; translations check clean; model-check 9/10 locally (10th = known local Node 25 + tsx env defect only; green in CI).
Prettier: clean on every file in the unit diff. src/eslint-suppressions.json: unchanged.
Updated this round (refresh onto main 9c069e94ef)
1d2373d80 - merge upstream/main. Same two test-file conflicts as B1; the ClineProvider.spec.ts pre-merge blob is byte-identical to B1's, so B1's resolution was reused verbatim (both sides' tests kept); ExtensionStateContext.spec.tsx takes main's DEFAULT_WRITE_DELAY_MS placeholder shape and keeps the perWriteCheckpoints key.
86f41828b - formatting-only: upstream main added a pnpm format:check step to the compile job (new gate); five files in this diff predate the gate and were reformatted with prettier --write (no semantic change; tests re-run green). The same fix was ported to every sibling unit carrying these files.
ba5908ba2 - review follow-up (ported from PR 1404): task-start baseline is now skipped on history resumes (initiateTaskLoop gates on _isHistoryTask), matching the exactly-once-per-task design; regression test added in Task.spec.ts. Task.spec 177/177 green, tsc clean, Prettier clean.
650382328 - review follow-up (ported from PR 1410): baseline skipped on already-aborted tasks (regression test added; Task.spec 178/178), and WriteToFileTool/EditFileTool now read perWriteCheckpoints through the shared DEFAULT_PER_WRITE_CHECKPOINTS constant. tsc clean, eslint clean, Prettier clean.
e443eb8bc - review follow-up (ported from PR 1410): the baseline block rechecks this.abort after the getState() lookup, so cancellation during the deferred state lookup skips the baseline save; regression test added (Task.spec 179/179, negative control verified). tsc clean, eslint clean, Prettier clean.
4c0bc15bc - review follow-up (ported from PR 1404): EditFileTool now awaits checkpointSave before the diff-state reset and queued-work handoff (fire-and-forget could race the commit and lose it at shutdown); held-promise regression test added (negative control verified). Tool specs 102 passed / 5 skipped, tsc clean, eslint clean, Prettier clean.
7b85cf223 - port: aborted tasks no longer dequeue queued messages (handoff sites guarded at the Task layer after the awaited-checkpoint change); regression test added. Task spec 180 passed.
82639ccd5 - Stryker-directive sweep: removed the seven carried // Stryker disable next-line comments in Task.ts's streaming/telemetry region (comment-only). Equivalences: event.name always a string on those paths; streamingKey never undefined there; getStreamingKey fallback unreachable defensive code. eslint/tsc/Prettier clean.
a3fb016db - refresh onto upstream/main (58341d8 lint cleanup) and fix the unused-variable fallout the merge exposed: dropped the unused ChangeJournalEntry import in the checkpoint index and renamed an unused test stub arg (_uri). Full-src eslint 0, tsc 0, journal spec 8 passed, Prettier clean.
Review-gate re-trigger (2026-08-30): empty commit 7b83143 (no code change) re-runs CI and CodeRabbit current-head review under the org new PR review gate; the code head remains 93a8329.
Visual regression note (2026-08-30): The advisory extension-host-visual check (chat-dark sidebar snapshot) fails on this branch with a deterministic 973-pixel delta localized to the completion-result area. Root cause: the B1 task-start baseline checkpoint (per-write checkpoints default on, allowEmpty) adds a suppressed checkpoint_saved row to the message history, which getCompletionCheckpoint() picks up, so SeeNewChangesButtons render below the completion row; the suite baseline (recorded pre-FWS in #1426) has no such buttons. Every other pixel is identical, and the delta is pixel-identical across all branches containing B1 (1404/1406/1410/1411/1412/1413), while non-B1 branches are green. This is a new-expected-behavior vs stale-baseline mismatch rather than a rendering regression. Flagged for maintainers: either update the electron-chat-dark-sidebar.png baseline on the B1 branch or adjust the scene/component behavior. Advisory check only — it does not block the required gates.
loadChanges now validates the runtime shape of every parsed journal line and skips non-entry-shaped JSON (torn append leaving a bare number or null, manual edits, missing string path/checkpointId, unknown operation), per the review thread; regression test covers a torn-but-valid line plus four other malformed shapes (negative control: reverting the check reddens exactly that test). eslint/tsc/Prettier clean.
Refreshed onto upstream/main (tool-call state scoping): ToolCallbacks gained a required toolCallId; the execute spec's callback fixtures pass it (test-tool-call-id, matching main's own spec convention). No production-code change. Full-src eslint 0, tsc 0, execute/journal/Task specs 226 passed.
Doc/test-name-only commit: the journal entry contract comment now describes the written-subset journaling of partially failed patches, and the execute-spec describe block is renamed to match the subset-checkpoint tests it contains. eslint/tsc/Prettier clean, spec 26 passed.
Persistence Integrity walkthrough row - fixed
appendChange now (1) repairs a torn tail - an unterminated final line is terminated before the new entry is appended, so a crash-truncated journal no longer splices the next entry into the fragment and lose both - and (2) fsyncs each append, so a durable checkpoint implies a durable journal entry. Regression tests: append-after-torn-tail loads both the prior valid entry and the new entry; clean-tail appends insert no blank line. Negative control: disabling the tail repair reddens exactly the torn-tail test (1 failed / 23 passed), restored byte-exact.
The proposed whole-file atomic-rename/serialization redesign is not adopted: the journal is advisory metadata (rollback reads checkpoint commits; loadChanges tolerates malformed lines by design), per-append fsync removes the durability gap, and whole-file replacement would trade the single-syscall append for an O(n) read-modify-write on every write.
Review follow-up on the journal hardening: the tail-inspection catch now suppresses only ENOENT (fresh journal) and propagates other stat/open/read errors, and the append loops on FileHandle.write until the whole record is written before syncing (a short write can no longer persist a torn entry under a reported success). Two regression tests; negative controls each redden exactly their test, byte-exact restore. eslint/tsc/Prettier clean, checkpoints suites green.
Upstream refresh (this push)
upstream/main advanced (threshold commit for the series), leaving the branch conflicting with main on the regenerated e2e screenshot asset only; merged upstream/main into the unit branch and resolved apps/vscode-e2e/src/visual/__screenshots__/electron-chat-dark-sidebar.png to main's version. The PR diff remains unit-only; no source hunks were altered by the merge.
Merged upstream main f707b6dfe (clean merge; gates and affected suites re-run green). Upstream enabled knip --production, which fails test-only production exports. Response on this head:
loadChanges carries an @internal tag (knip 5.60 has no export-level ignore config; the tag is its native mechanism, documented at the export site): it is wired by the rollback unit later in the split chain. appendChange stays - it is production code in this unit.
Updated this round (row-13 walkthrough fixes at 43b49b771)
Journal directory fsync on creation: when an append creates the journal file, appendChange now fsyncs the journal's parent directory before the append is reported as committed, so the new file's directory entry survives a crash. Platforms that cannot open the directory for sync degrade to a warning, mirroring the rename path's tolerance list.
loadChanges no longer swallows real read failures: an absent journal is still an empty history, but any other read failure (permissions, I/O) propagates instead of being reported as an empty rollback history.
Catch-path write-metadata flush: each completed write is recorded through an onWrote callback at the moment it lands on disk, and the catch path flushes the accumulated checkpoint/journal metadata (awaited) so a throw from post-write bookkeeping cannot lose the record of a completed write.
perWrite setting wording: the description now states that a multi-file patch produces a single checkpoint (all 18 locales; labels and keys unchanged).
Each fix carries a focused regression test; negative controls verified exactly-1-red per behavior.
Row-14 wave (round 49)
Task-start baseline hardening (byte-identical across all five units): settings-read rejection falls back to default-on (task startup continues); the baseline-done flag is set only after an explicit disable/abort or a committed save, so a no-commit save is retried on a later loop entry. Two regression tests; negative controls each exactly-1-red.
getCheckpointService never stores an uninitialized service (byte-identical guard across all five units): failed Git check / initShadowGit resolves to no service and clears the initializing flag. New getCheckpointService.spec.ts; negative control exactly-2-red.
Row-15 wave (round 50)
Move journaling completes the rollback story: a completed move now journals its source deletion ({operation: "delete"}) after the destination write, so a step rollback restores the removed source; a move whose source unlink failed keeps the single destination entry (the source is still on disk). Builder logic byte-identical across B2/B3a/B3b/B3c; the path-driven rollback needed no change. Regression tests for both outcomes; negative control exactly-1-red.
Catch-flush ordering hardened: writeMetadataFlushed is set only when the flush proceeds to checkpointSave and perWriteCheckpoints is cached for the catch flush - a rejecting settings read between write and flush no longer skips persisting writes already on disk. Regression test + exactly-1-red NC.
Catch-flush failures are reported: a rejected catch-path checkpoint flush is no longer swallowed; the reported error keeps the original message and appends the persistence failure (original preserved as cause). Regression test + exactly-1-red NC.
This push also retriggers CI after the known webview-ui vitest teardown flake on the previous head (2086/2086 tests had passed; zero assertion failures).
Row-16 disposition (evidence-grade, no code change)
The Persistence Integrity walkthrough row at this head restates two claims, both already dispositioned or superseded by landed code:
"successfulChanges is updated only after each handler returns; the outer catch reaches without calling checkpointSave" - stale against this head. Every handler records its write through the onWrote callback at the moment the write lands on disk (ApplyPatchTool.ts:377 add, :445 delete, :617 move destination, :629 update - each with a comment naming the throw it survives), and the outer catch performs an awaited flush of the recorded writes (landed at 43b49b7, hardened at 78275a3: the flush flag is set only when the success path proceeds to checkpointSave, the settings lookup is cached for the catch, and a rejected catch flush is reported alongside the bookkeeping error). The row's cited ApplyPatchTool.ts:244-247 is now the awaited success-path flush itself. Regression coverage: "journals the recorded write when a handler throws after its write", "flushes the recorded write from the catch path when the settings read rejects", "reports the catch-path flush failure alongside the bookkeeping error" (negative controls exactly-1-red each).
"checkpointSave commits first and appends the journal afterward; append errors are logged and swallowed" - the registered disposition stands: the journal is advisory metadata (rollback reads checkpoint commits; loadChanges tolerates malformed lines by design), per-append fsync removes the durability gap, torn-tail repair closes the crash-splice window, and a journal failure deliberately never propagates to the checkpoint error handler (checkpoints stay enabled; index.ts:269-271). The transactional CheckpointPartialPersistenceError hardening of this window is owned by the B3a+ units and landed there; adopting whole-file atomic replacement in B2 was evaluated and rejected (O(n) read-modify-write per append) with rationale above.
Row-17 confirmation (REPEAT - registration confirmed, no churn)
The 03:05Z Persistence Integrity row drops the earlier write-recording claim - it now states explicitly that "The ApplyPatch write-recording and awaited catch flush address the earlier bookkeeping-throw path" (the Row-16 disposition accepted). The remaining claim is the commit-then-append window, the registered advisory-journal disposition above (per-append fsync, torn-tail repair, journal failure logged without disabling checkpoints, transactional CheckpointPartialPersistenceError owned by B3a+; the pending-record transaction redesign is the same whole-file-redesign family evaluated and rejected above). Verdict: REPEAT.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
Automatically save checkpoints after successful file writes, including available change details. A multi-file patch creates one checkpoint.
Save a baseline checkpoint when a task starts by default.
Enable or disable per-write checkpoints in settings; they’re enabled by default.
Keep a record of file changes associated with checkpoints to support recovery.
Localization
Added translated labels and descriptions for the per-write checkpoint setting.
Bug Fixes
Avoid recording changes for failed writes or unchanged files.
Preserve records for successful writes when other operations in a multi-file change fail.
Skip processing queued input after a task has been aborted.
The change adds a default-on perWriteCheckpoints setting, task-start baseline checkpoints, and a per-task JSONL change journal. File-writing tools pass operation metadata and available diff statistics to checkpoint saves. The settings UI exposes the option in multiple locales.

Checkpoint service and change journal src/core/checkpoints/changeJournal.ts, src/core/checkpoints/index.ts, src/core/checkpoints/__tests__/*
Adds per-task JSONL journaling, pending-marker recovery, and journal entries for committed checkpoint saves. Tests cover journal operations, recovery, and checkpoint-save outcomes.
Task-start baseline and abort handling src/core/task/Task.ts, src/core/task/__tests__/Task.spec.ts
Attempts an awaited baseline checkpoint for eligible tasks. Aborted tasks do not dequeue queued messages.
Resolve the journal recovery and completed-write recording gaps before merging. Some failures can leave saved changes without their expected checkpoint metadata, and malformed recovery records can prevent subsequent checkpoints.

Full details: Title check
Explanation
The title names the feature, the per-task change journal (changes.jsonl), and the torn-tail repair behavior. The changeset adds an append-only changes.jsonl journal with torn-tail repair on load and append, so the title matches the main change. The title includes a tracking reference (B2, #1375) that does not describe the change, and the 76-character length is acceptable but slightly long for a short title. The title is clear and specific enough for a reviewer scanning history.
Full details: Description check
Explanation
The description follows the repository template partially. It links a tracking issue (#1398) but does not use the template's 'Closes: #<issue>' line, and it lists the series context instead. It has a clear What section, a Tests section with commands and expected results, and a Pre-Submission-style verification record. It covers the how only partly: it omits the Documentation Updates choice, the Visual Snapshots decision for the UI-adjacent i18n and settings changes, and the Get in Touch field. The description also contains a long run of update logs, commit hashes, and review-round notes that make it hard to read. A reviewer can still identify the change and the test approach, so the description is mostly complete.
Full details: Security Boundaries
Explanation
The prior finding remains unresolved. src/core/checkpoints/changeJournal.ts:207-228 reads pending-marker entries without validating them. A marker containing {"state":"ready","entries":[null]} throws when recovery reads entry.path. src/core/checkpoints/index.ts:272-287 then skips the per-write checkpoint. The invalid marker remains and can block later saves.
Resolution
Validate every pending-marker entry before using or appending it. Warn and remove unreadable markers, then continue safely. Add regression tests for null, primitive, missing-field, invalid-operation, and invalid-path entries, including the checkpoint-save path.
Full details: Persistence Integrity
Explanation
A committed checkpoint can lose its journal metadata. In src/core/checkpoints/index.ts:277-280,291-356, the pre-commit marker contains no write metadata. If both ready-marker promotion and incomplete-marker persistence fail, the outer catch returns without propagating the error. changeJournal.ts:196-232,386-389 then discards the awaiting marker on the next load. A crash after the commit but before promotion has the same result. The test at checkpointJournalPromotion.test.ts:164-175 confirms that the double-failure path leaves only the non-recoverable marker.
Resolution
Persist a durable pre-commit intent with enough information to identify the committed checkpoint and reconstruct its journal entries. Reconcile that intent after a crash or promotion failure, or roll back the checkpoint. Propagate unrecoverable persistence errors to the write path. Add tests for a crash after commit and for failure of both marker writes.
Full details: Regression Evidence
Explanation
The new checkpoint setting still lacks required regression evidence. SettingsView.spec.tsx now tests a true-to-false toggle and a default-valued payload, but does not test a stored false reaching the control or an unset value reaching the payload fallback. The fallback test starts from a context whose perWriteCheckpoints default is true. The new checkbox and description in CheckpointSettings.tsx also lack a Playwright component snapshot. webview-ui/AGENTS.md:48 requires a committed snapshot for visible UI changes. The prior failure is therefore only partly addressed.
Resolution
Add SettingsView coverage for a stored false and an unset perWriteCheckpoints, including the displayed value and saved payload. Add a Playwright component visual test for the checkpoint settings surface and commit its reference snapshot.
Full details: Lifecycle Resource Cleanup
Explanation
The prior lifecycle race remains. The new baseline in Task.ts:3856-3873 can wait for checkpoint initialization while the task is disposed. checkpointSave then saves without rechecking abort (index.ts:256-292), and its listener can post a message and call task.say after disposal (index.ts:183-206). A restarted task can run checkpoint work at the same time. Initialization also remains non-single-flight: the listener clears the initializing flag before the service is assigned (index.ts:122-134,178-181), so the new baseline lookup can start a second service.
Resolution
Use a single in-flight initialization promise and keep it active until assignment. Invalidate initialization on disposal, remove service listeners, and release the service. Recheck cancellation before assigning a service, starting checkpoint work, and emitting checkpoint effects. Add regression tests for disposal during initialization and concurrent baseline initialization.

single source of truth for both settings UI and task behavior.
Apply the same fix in `@webview-ui/src/context/ExtensionStateContext.tsx` at line
214: The initial webview state hardcodes the setting default instead of using
the shared constant.
In `@src/core/tools/__tests__/applyPatchTool.execute.spec.ts`:
- Around line 81-85: Update the providerRef fixtures in the affected tests to
use precise test-double types instead of unnecessary as unknown as
Task["providerRef"] assertions; if either double assertion is required, retain
it and add a nearby comment explaining why the mock cannot satisfy the concrete
Task member types.
In `@webview-ui/src/components/settings/CheckpointSettings.tsx`:
- Around line 45-46: Replace the explicit any types in CheckpointSettings,
including the perWriteCheckpoints checkbox handler, with a precise checkbox
change-event type and narrow mock prop/event types. Update
CheckpointSettings.tsx lines 45-46 and CheckpointSettings.spec.tsx lines 24-56
so checked is type-validated and the mock contracts are explicit.

The test verifies writeFile content and one checkpointSave call. It does not verify the journal payload. The tool maps a move to change.movePath for the entry path. Add that assertion so a regression in the destination mapping fails here.

Review-state labels are managed by this workflow; do not edit them manually. community-approved is managed the same way — do not add or remove it manually. It signals a fresh community code approval for the current head as an advisory priority only; maintainer review is still required.

extension-host-visual on this head: read-only adjudication attempt, verdict insufficient evidence (ours-leaning, chain-correlated). Two discriminating facts, both measured just now:
main does not run this lane at all. Paged GET /commits/e943530c848624bd3054c960be1e4fb0b658509a/check-runs?per_page=100&filter=all over 4 pages: 300 check runs, 0 failures, and no run whose name matches visual/extension-host. So the lane cannot be called environmental by pointing at a red base — the base never runs it.
Run shape on this head: started 15:45 -> completed 15:59 (~14 min), failed step Run Extension Host visual tests, 0 check-run annotations, and job logs are 404 for the token in use (no Actions:read), so the suite output is not reachable from the API.
What would settle it, maintainer-side: (a) Actions:read so the failing job log can be read, or (b) a one-off run of this workflow for #1404's head (fc11d6d64) against main. Until then I am deliberately not classifying it as advisory.
Unrelated to this lane, for whoever books reviews: live-row counts (GraphQL reviewThreads filtered on isResolved=false AND isOutdated=false) are 0 on all five chain heads as of now — #1404 fc11d6d64, #1406 2a67969fc, #1411 029c25ac3, #1412 dd8b4fd6a, #1410 5e9f60820 (heads verified with git ls-remote against the fork, not upstream). Zero live rows is not the same as a cleared review decision: #1404's newest three reviews contain a CHANGES_REQUESTED at 2026-10-22T10:27 followed only by COMMENTED, with nothing approving over it.
Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Show when per-write checkpoints are unavailable.
When enableCheckpoints is false, this checkbox can still appear checked and accept changes. getCheckpointService returns no service in that state, so no per-write checkpoint is created. Disable the control and explain its dependency on automatic checkpoints.

resolve perWriteCheckpoints when it is still undefined; if the settings lookup
fails, preserve the default-on behavior. Add a test where getState returns
perWriteCheckpoints as false and trackFileContext rejects, and assert

including its per-write checkpoint control, and commit a matching visual
baseline so the new settings markup is covered by a visual snapshot.
Review comments at @webview-ui/src/components/settings/SettingsView.tsx:
- Line 418: Add focused SettingsView tests that toggle perWriteCheckpoints both
on and off, save each setting, and verify the saved payload; also verify that an
unset value uses DEFAULT_PER_WRITE_CHECKPOINTS. Cover persistence and returned
webview state only where needed to confirm these settings survive the save flow.
Review comments at @webview-ui/src/i18n/locales/en/settings.json:
- Line 774: Update the checkpoint setting description to name only tools whose
handlers create a checkpoint after a successful write; do not imply this applies
to apply_diff, whose dispatcher checkpoints before the operation. Apply the same
supported-tool wording to the corresponding descriptions in all locales.

Failed pre-merge checks:
- Regression Evidence:
Add focused `SettingsView` tests for unset, `true`, and `false`
`perWriteCheckpoints` values. Assert that each value reaches
`CheckpointSettings` and appears in the `updateSettings` payload. Add a
Playwright component visual test for the checkpoint settings surface and commit
its required reference snapshots.
- Security Boundaries:
Validate every pending-marker entry with `isChangeJournalEntry` before
constructing keys or calling `appendChange`. Treat invalid entries as an
unreadable marker, warn, remove the marker, and continue without those entries.
Add regression tests for null, primitive, missing-field, invalid-operation, and
invalid-path marker entries, and verify that `checkpointSave` still follows the
intended safe failure behavior.
- Persistence Integrity:
If ready-marker promotion and incomplete-marker persistence both fail, do not
leave a committed checkpoint represented only by `awaiting-checkpoint`. Roll
back or mark the checkpoint incomplete in durable storage that reconciliation
will retain. Propagate the persistence failure to the write path, and add a test
that forces both marker writes to fail and verifies that the committed write
remains recoverable.
- Lifecycle Resource Cleanup:
Implement single-flight checkpoint initialization. Store an in-flight
initialization promise before the first await and return it from every caller,
including the baseline path. Keep initialization active until the service is
assigned. On failure, remove registered listeners and release the service. On
task disposal, invalidate the in-flight initialization, remove checkpoint
listeners, and release the initialized service. Check `abort` or disposal state
before storing the service and before checkpoint work or checkpoint effects.

103-104: Pending and incomplete markers are still not crash-durable.
writePendingJournal and writeIncompleteJournal write a staging file and rename it. Neither syncs the staging file before the rename. Neither syncs the parent directory after the rename. A crash after the rename can leave an empty or truncated marker. reconcilePendingJournal then discards that marker as unreadable. The ready entries are lost. This is the case the marker exists to survive. Write through a handle, call handle.sync() before the rename, and sync the parent directory after it. Reuse one directory-sync helper with appendChange.
Based on learnings: "After creating or renaming a file that must survive a crash, also fsync the parent directory's file descriptor."
Also applies to: 140-141

218-231: Marker entries are still not validated in reconcilePendingJournal.
reconcileIncompleteJournal filters entries with isChangeJournalEntry. This function does not. A ready marker with a null element makes entry.path on Line 224 throw. The marker stays on disk.

289-311: Directory sync does not cover directories that fs.mkdir just created.
appendChange syncs only checkpoints/. If recursive mkdir created checkpoints/ or tasks/<id>/, the directory entry of each new directory lives in its parent. Syncing checkpoints/ does not persist those entries. Sync the parent of each newly created directory. Extend the creation test to assert those syncs and their order.

196-233: Stability & Availability
The reported duplicate-entry race is not established. The seen set and the sequential ordering inside checkpointSave cover the single-save path the code runs. The second entry point, loadChanges, has no production caller in this checkout, so it cannot overlap a save today. The only way to reach overlapping same-task reconciles would be two concurrent journal-bearing saves, and the inspected call sites all await their saves inside tool handlers. The comment's proposed per-task promise chain depends on that unestablished premise, so it is not a supported change request.
178-192: The reconcile-failure test does not assert the persisted recovery record.
The test checks the returned commit, enableCheckpoints, and the error log. It does not read pendingJournalPath(...) after checkpointSave. A regression that drops the ready marker would still pass. Assert state: "ready" and the entry with checkpointId: COMMIT.

Answered, and left open deliberately: this row needs a maintainer decision, and the honest thing I can do from here is measure the surface rather than commit an unverifiable baseline.
Mechanism. A CheckpointSettings.visual.tsx story would be the first visual test of anything wrapped in SearchableSetting — that component appears in 0 of the branch's visual files, so the row wrapper, the label, the description line and the checkbox would all be new baselines, plus a story id in webview-ui/playwright/gallery/stories.tsx (terminal-settings is the nearest template). That is a new visual surface, not a test case.
The count that separates behaviour from pixels. Behaviour is already covered: CheckpointSettings.spec.tsx:80 (description text and test id), :93 (control test id), :106 (falls back to DEFAULT_PER_WRITE_CHECKPOINTS when the state is unset), :114 (posts updateSettings with perWriteCheckpoints: false), :123 (checked reflects the stored value). Pixels are covered zero times for this surface: the branch carries 28 *.visual.tsx files and 12 toHaveScreenshot call sites, and none of them touches SearchableSetting or the checkpoint settings component.
Job state, stated as history rather than as a fact. In the run attached to the head you reviewed, extension-host-visual (job 126024088263, run 41666775346) failed on three electron-chat-dark-sidebar.png diffs through locator('.part.sidebar') while webview-visual (126024088881) and theme-fixtures (126024088915) were success — so a new webview story joins the leg that was green, not the leg that was red. The lead's own read of the last 24 runs of that workflow at job level finds 21 completed legs with zero test failures, so I am not calling that red run stale; I will re-read the job on this push's run and report if the same three sidebar failures come back, because then the answer changes.
Why I am not implementing it on this box. It cannot run Playwright visual at all. A committed .visual.tsx plus png baseline written here would be a baseline nobody verified — the failure mode where the test passes because the author's own pixels were committed.
Question for the maintainers: do you want a visual job for the checkpoint settings surface in this PR (new story id, new gallery entry, committed screenshots for the theme set), or as a follow-up filed together with the other SearchableSetting rows so the first one sets the pattern for the rest? If you want it in this PR, name the theme set and I will take it as its own unit. This row stays open until you say.
@easonLiangWorldedtech Thanks for separating behavior coverage from visual coverage. I agree that an unverified baseline should not be committed.
My recommendation is to add the visual test in this PR, subject to the maintainer’s decision. The repository’s visual-test guidance calls for a baseline for a visible UI change. I recommend the existing visualThemes set: dark, light, high contrast, and high contrast light.
If Docker cannot run locally, webview-ui/AGENTS.md documents a fallback: push the test without baselines, dispatch the pinned visual workflow, inspect its image artifacts, commit the container-generated baselines, and rerun the job. A maintainer can dispatch it if needed.
One correction: CheckpointSettings.spec.tsx checks the cached-state setter; it does not verify the SettingsViewupdateSettings payload. That coverage remains separate. I have not checked the current visual job or determined the cause of the earlier extension-host failure.

Follow-up on the visual-leg point in my answer, because the re-run you asked for landed on this head and I would rather correct the record than let it stand.
The extension-host-visual leg is red on this head too (job 128547911683 in run 42420577786, step "Run Extension Host visual tests": 3 failed / 10 passed, all three "expect(locator).toHaveScreenshot(expected) failed" on locator('.part.sidebar') with Snapshot: electron-chat-dark-sidebar.png, and that is the only snapshot name in the log). Measured wider than my own two runs: the failure is recurring across unrelated branches inside the same workflow's last 200 runs - 8 failing legs, 4 of them this exact sidebar shape, on feat/prompt-history-picker (twice), feat/session-title, and this branch twice (2a67969fc7 and e12e961c6). The other four failing legs are different shapes (two renovate/npm-lmstudio-sdk-zod-vulnerability with 7 failed, two with no test tally at all), so that job fails for more than one reason and none of them is a checkpoint-settings story.
So the ask is bigger than this thread and smaller than it looks: the re-run request now covers three jobs across three branches, and we are not implementing Playwright visual baselines from a box whose Playwright runs cannot execute the harness. What the part of the ask that this row is about would gain is exactly what you asked for - the test is blocked on a new webview story, and webview-visual, the leg such a story would actually join, is success on this same head (job 128547911897). Leaving the thread open for a maintainer call on whether that story is coming; the accessibility-naming and saved-false coverage you asked for is on the branch at SettingsView.spec.tsx:542.

@easonLiangWorldedtech Thanks for checking. I agree that an unverified baseline should not be committed.
The reported webview-visual pass does not cover the new control without a story. The recurring sidebar failures merit separate investigation; their cause is still unverified. I have not independently checked the CI results or the SettingsView.spec.tsx coverage.
This thread can remain open for the maintainer’s decision on the story and verified baseline. Separately, the saved pre-merge assessment reports blocking security and persistence findings. Those need verification against the current head before merge.

Answered against the current head, because you asked for verification rather than agreement. The saved assessment you point at is review 5815496498, submitted 2026-11-07T23:10:05Z against commit e12e961c6146; the head is c1b051b2786a and exactly one commit has landed since it — c1b051b278 "fix(checkpoints): sync journal markers before rename, guard and merge marker entries", 2026-11-08T08:32:50+08:00, 395 added / 31 deleted over 7 files (changeJournal.spec.ts 157+/1−, changeJournal.ts 110+/21−, checkpointJournalPromotion.test.ts 51+, index.ts 7+/4−, ApplyPatchTool.ts 8+/5−, applyPatchTool.execute.spec.ts 33+, checkpointJournal.test.ts 29+). Read against the head, both of the findings you named are met; the visual half of this thread is not, and that half is what is still waiting on a maintainer.
Security boundaries — met, with the tests named. The guard is isChangeJournalEntry at src/core/checkpoints/changeJournal.ts:81-91: it rejects candidate === null and any non-object (so a bare null or a primitive arriving from JSON.parse cannot throw on entry.path), requires path and checkpointId to be strings, and whitelists operation to the two values the journal defines. It is applied on every marker read. The regression tests you asked for exist: src/core/checkpoints/__tests__/checkpointJournal.test.ts:224 feeds 1, null, a missing checkpointId, an unknown operation rename and a non-string path 42 and asserts that only the well-formed line survives; :274 is the same corruption arriving through the pending marker — an array carrying null and a half-shaped element — and asserts the valid entry is appended and the marker is cleared, which is the difference between a dropped entry and corruption that blocks every later checkpoint save; changeJournal.spec.ts:346 and :356 cover the invalid-path class by rejecting task IDs that could escape the tasks directory.
Persistence integrity — met, with the durability ordering you asked for. The pending marker is a hard prerequisite of the commit, not a courtesy: src/core/checkpoints/index.ts:278-288 returns undefined without committing when the pre-commit marker cannot be written, and disables checkpointing for the task rather than continuing unpersisted. Both staging-and-rename writers sync the staged marker before the rename and sync the containing directory after it (changeJournal.ts:101, :149, :330, :374-399, with an explicit tolerance list EINVAL/EISDIR/EBADF/ENOTSUP/EOPNOTSUPP/EPERM that degrades to a warning instead of failing a write). Tests: changeJournal.spec.ts:237 (pending marker synced before rename), :259 (directory synced after rename), :275 (platforms that cannot sync the directory), :304 (incomplete marker synced before replacement), :106 (a partial write still writes the full record), :325 (an existing incomplete marker's entries are carried and merged, not replaced), checkpointJournal.test.ts:310 (no duplicate entries after a crash between commit and marker promotion), plus checkpointJournalPromotion.test.ts for the retry-once, record-into-incomplete and disable-on-awaiting-failure paths.
The two gate rows that are not about pixels. The same assessment also lists Regression Evidence and Lifecycle Resource Cleanup. Regression Evidence's behaviour half is met: SettingsView.spec.tsx:542-570 proves that a stored true the user un-checks reaches the payload as perWriteCheckpoints: false — with the key named, because objectContaining would pass on a missing key — and :534 covers the default round trip, on top of CheckpointSettings.spec.tsx:80/93/106/114/123 for the control itself. Lifecycle is a real gap and I am not claiming it fixed: at head there is no single in-flight initialization promise in src/core/checkpoints/index.ts (getCheckpointService.spec.ts:75/97/111 prove only that a failed initialization is not stored). But this PR adds 13 of its 143 new lines inside that initialization block (new-side lines 125-133 and 221-224); the init/dispose shape the gate wants reworked is upstream code, and I would take it next to #2351 as its own change rather than smuggle it into this PR.
So, this thread. The security and persistence findings are answerable by evidence and are answered above; the story plus committed baseline is a maintainer decision and not an author one, for the reason already on the record — a CheckpointSettings.visual.tsx baseline would be the first visual test of anything wrapped in SearchableSetting (that wrapper appears in 0 of the branch's visual files), so it is a new surface whose PNG nobody can verify from this host, while extension-host-visual is already red on unrelated branches for the .part.sidebar snapshot. The thread stays open for that decision. For the record, and because this PR keeps getting swept into the family's exclusion asks: 1406 is not width-blocked — deciding extension package 468 counted executable lines against the 500-per-package cap, its own mutation-diff leg #8576 success at 151,988 B and 1,937 lines with zero gate sentences — see pointer comment 6753029279.

@easonLiangWorldedtech Thanks for the detailed evidence. I checked head c1b051b2786a.
Security: The guard now filters null and malformed pending entries. The test at checkpointJournal.test.ts Line 274 checks that valid entries survive and the marker is cleared. I did not run the tests.
Persistence remains blocking: The pre-commit marker still has no write metadata (index.ts Line 277). A crash after the commit but before promotion leaves only that marker, which recovery clears. The test at checkpointJournalPromotion.test.ts Line 200 explicitly expects an empty journal in this case. The test at checkpointJournal.test.ts Line 310 covers a ready marker after an append, not a crash before promotion. Please add a recoverable pre-commit intent or rollback, propagate unrecoverable errors, and test both failure paths.
Settings evidence: Line 542 tests a true-to-false toggle. The test at Line 513 does not set perWriteCheckpoints to undefined, so it does not establish that the payload fallback runs. A stored-false SettingsView round trip also remains untested. I used the supplied regression-evidence guidance for this assessment.
Lifecycle: The initialization mechanism predates this PR, but the new baseline adds a path that can wait for it during disposal. I acknowledge your proposal to handle the broader lifecycle work separately. Would you like a follow-up issue alongside #2351 to track the disposal-during-initialization check?
The visual thread remains open for the maintainer’s decision. I agree that an unverified baseline should not be committed.

Learning: Regression evidence: Fail only when a concrete changed behavior lacks focused coverage at the lowest valid test layer, tests merely mirror implementation, an affected error/negative/unset branch is omitted, or a durable visible UI change lacks its required Playwright component snapshot.

Add a mixed-entry recovery test covering both invalid and valid marker entries.
- Around line 215-219: Update the fresh-promotion path around the ready-marker
check and readJournalEntries so each promotion does not parse the full journal;
use a bounded way to identify entries needing promotion while preserving
idempotent recovery after a crash. Establish how already-promoted entries are
recognized before removing the full-history read, so retries neither duplicate
nor lose entries.
- Around line 103-104: Update both marker writers in the changeJournal flow to
sync each staged marker to durable storage before renaming it, then sync the
containing directory after the rename. Preserve the existing staging and
promotion behavior while ensuring both writers follow this ordering.
Review comments at @src/core/checkpoints/index.ts:
- Around line 277-280: Update the checkpoint flow around writePendingJournal so
the pre-commit journal record persists the write metadata and a stable
transaction identity before Git commits; ensure restart recovery uses that
identity to reconcile the record with the resulting commit instead of discarding
it. Preserve the existing journal and commit safeguards, and use the established
recovery mechanism and identity semantics rather than introducing an unverified
API.
- Around line 276-280: Serialize checkpoint saves and journal reconciliation per
task, keyed by task.taskId, so an older save cannot have its ready marker
replaced before its entry is recorded. Ensure the serialization covers the full
save-and-reconcile transaction, reusing an existing per-task mechanism if
available.
- Around line 344-345: Update the incomplete-journal persistence flow around
writeIncompleteJournal to retain entries already stored for the same task.taskId
and combine them with the current entries before writing. Apply this
preservation on the failed ready-promotion path even when reconciliation fails,
reusing the established journal-reading and reconciliation mechanisms.
Review comments at @src/core/tools/ApplyPatchTool.ts:
- Around line 280-285: Update the checkpoint failure handling around
checkpointSave so a genuine journal persistence failure after both marker writes
fail is propagated as a distinct failure to handleError, rather than being lost
when checkpointSave resolves undefined. Preserve the behavior for disabled or
empty checkpoints so they are not reported as failures, and add a test that
exercises the real persistence-failure path.
- Line 210: Update the ApplyPatchTool write flow to call onWrote immediately
after writing the destination and before attempting source deletion or reporting
an unlink failure. Ensure the destination is recorded in the catch-path journal
even if task.say rejects, while preserving the existing successfulChanges
handling.
Review comments at @webview-ui/src/i18n/locales/en/settings.json:
- Around line 773-774: Update the checkpoint label and description in the
settings locale entry to name only tools that actually create a post-write
checkpoint; do not imply that apply_diff does so. Align the corresponding label
and description across the other locale files while preserving the existing
checkpoint behavior.
---
Outside diff comments:
Review comments at @src/core/tools/EditFileTool.ts:
- Around line 468-480: Move the awaited per-write checkpointSave call before
result reporting in the EditFileTool flow, after the edit is saved and marked
with task.didEditFile. Keep its journal metadata and error handling unchanged,
and ensure checkpointing completes before pushToolWriteResult, pushToolResult,
or diff reset.
Review comments at @src/core/tools/WriteToFileTool.ts:
- Around line 188-200: Move the per-write checkpointSave call in the
WriteToFileTool flow to run after task.didEditFile is set and before
pushToolWriteResult or pushToolResult can report the write. Preserve the awaited
checkpoint and its existing arguments so a saved write gets a checkpoint attempt
even if reporting is cancelled or rejects.

Failed pre-merge checks:
- Regression Evidence:
Add SettingsView coverage for a stored false and an unset `perWriteCheckpoints`,
including the displayed value and saved payload. Add a Playwright component
visual test for the checkpoint settings surface and commit its reference
snapshot.
- Security Boundaries:
Validate every pending-marker entry before using or appending it. Warn and
remove unreadable markers, then continue safely. Add regression tests for null,
primitive, missing-field, invalid-operation, and invalid-path entries, including
the checkpoint-save path.
- Persistence Integrity:
Persist a durable pre-commit intent with enough information to identify the
committed checkpoint and reconstruct its journal entries. Reconcile that intent
after a crash or promotion failure, or roll back the checkpoint. Propagate
unrecoverable persistence errors to the write path. Add tests for a crash after
commit and for failure of both marker writes.
- Lifecycle Resource Cleanup:
Use a single in-flight initialization promise and keep it active until
assignment. Invalidate initialization on disposal, remove service listeners, and
release the service. Recheck cancellation before assigning a service, starting
checkpoint work, and emitting checkpoint effects. Add regression tests for
disposal during initialization and concurrent baseline initialization.

Answered on #1406 with the mechanism, and leaving this thread open: the ask is a design change, and answering it is not landing it.
Your model of the interleaving is the one I would defend. There is no lock in this area — a search for mutex|AsyncLock|withLock|semaphore across src/core/checkpoints and src/services/checkpoints returns zero hits — and the path really is re-entrant: Task.ts:2429 runs void this.checkpointSave(false, true) fire-and-forget, Task.ts:3873 awaits checkpointSave(true, true) for the baseline, presentAssistantMessage.ts:1200 awaits task.checkpointSave(true), and the patch tool flushes from both its success path and its catch path. Two of those can be in flight for one task, the pending marker is one file per task, so the last writer wins and the folds interleave.
Two measurements before proposing anything. This is not something the series introduced: git blame -L 2425,2432 at the previous head e12e961c61 and at the merge base 3ee042d91e attributes every line of that block, the fire-and-forget included, to 19f306e6580ecc769ad5e2b56a97ca83447e6e53 (Naved Merchant, 2026-08-05), which git merge-base --is-ancestor confirms is an ancestor of main tip 73931fe8be — pre-existing upstream behaviour this series inherits, not a race this PR opened. And the unit boundary: a per-task serialisation point is a new concurrency primitive for a subsystem that has none, and it changes the cost of every checkpoint save, so it wants its own change with its own tests rather than arriving inside a durability commit.
Mechanism agreed; the primitive and its owner (per-task promise chain vs a real async lock, write-owner vs checkpointSave) proposed as its own unit. Leaving the thread unresolved for a maintainer to weigh in.
The reason will be displayed to describe this comment to others. Learn more.
@easonLiangWorldedtech Thanks for tracing this. The overlapping checkpoint calls predate this PR, based on your history check. The shared pending marker is new, so journal-entry loss is the PR-specific consequence.
I understand the preference to handle serialization as a separate change. This thread can remain open for a maintainer’s decision.
Would you like me to open a GitHub issue for the serialization change and concurrent-save regression tests?
The reason will be displayed to describe this comment to others. Learn more.
Yes, please open it — a tracked issue is what I wanted this thread to leave behind, and a title that names both halves is better than my phrasing was.
Your correction is right and I want it on the record rather than implicit: the overlapping calls are upstream (Task.ts:2429void this.checkpointSave(false, true), blamed to 19f306e6580ecc769ad5e2b56a97ca83447e6e53, an ancestor of main tip 73931fe8be), but the shared pending marker is new in this series, so journal-entry loss under two in-flight saves is this PR's consequence, not the pre-existing race's. My comment said "pre-existing" about the re-entrancy, which is accurate; read as a claim about the failure mode it was too broad, and the loss mode is the half that matters.
For the issue body I would want three things: (a) the primitive and who owns it — a per-task promise chain at the checkpointSave entry, or a lock owned by the write-owner; (b) the per-save identity, because one marker file per task cannot tell two transactions apart, which is the same object the sibling row on the awaiting marker raises; and (c) concurrent-save regression tests that fail against today's code rather than passing either way.
Keeping the thread open as agreed. If no issue appears within a day I will file it myself with the blame evidence and both thread ids in its body so the trail survives.

Add deterministic regression tests for overlapping saves.In `src/core/checkpoints/index.ts`, a write checkpoint reconciles and writes a pending marker before saving, then promotes and reconciles that marker after the commit. `src/core/checkpoints/changeJournal.ts` uses one pending marker per task. If two saves overlap, one save can replace another save's marker before reconciliation and cause a committed checkpoint's journal entry to be lost.Overlapping checkpoint calls predate this PR. The author traced the fire-and-forget call in `src/core/task/Task.ts` to commit `19f306e6580ecc769ad5e2b56a97ca83447e6e53`, which is an ancestor of main tip `73931fe8be`. The shared pending marker and the resulting journal-entry loss are introduced by this series.## Required work- Choose and document the owner and scope of the serialization primitive. Consider a per-task promise chain at `checkpointSave` or a lock owned by the write owner. Cover the full save-and-reconcile transaction, including coordination with journal recovery, and account for old and resumed task instances sharing a task ID.- Define a per-save transaction identity. A single marker keyed only by task cannot distinguish concurrent transactions. Coordinate the identity and marker design with recovery of an `awaiting-checkpoint` intent, including how recovery distinguishes a committed save from one that did not commit.- Add deterministic concurrent-save regression tests with controlled interleavings. The tests must fail against the current implementation and verify that each committed save retains its own journal entries. Include overlap across old and resumed task instances and marker promotion/reconciliation; cover recovery interactions where applicable.## References- Pull request: https://github.com/Zoo-Code-Org/Zoo-Code/pull/1406- Concurrent-save review thread: https://github.com/Zoo-Code-Org/Zoo-Code/pull/1406#discussion_r4504098917- Related `awaiting-checkpoint` review thread: https://github.com/Zoo-Code-Org/Zoo-Code/pull/1406#discussion_r4504098923- Requested by @easonLiangWorldedtech: https://github.com/Zoo-Code-Org/Zoo-Code/pull/1406#discussion_r4504399821EOF)"
@easonLiangWorldedtech Created #2351. It covers serialization ownership, per-save identity, regression tests, and links to both review threads.

Yes, the issue exists and it carries the title you offered: #2351 "Serialize checkpoint journal transactions and add concurrent-save regression tests", opened 2026-11-08T00:56:14Z by @coderabbitai[bot], state open. That is what I wanted this thread to leave behind, so the ask is tracked rather than parked here.
Measured against the head as of now (c1b051b2786a), so the record is current rather than remembered. There is still no lock in this area — mutex|AsyncLock|withLock|semaphore returns zero hits across src/core/checkpoints and src/services/checkpoints — and the path is still re-entrant: Task.ts:2429void this.checkpointSave(false, true) remains fire-and-forget. What the commit that landed after your review did change is the consequence shape. c1b051b278 (2026-11-08T08:32:50+08:00) guards marker entries (changeJournal.ts:81-91), merges an existing incomplete marker's carried entries instead of replacing them, and syncs each staged marker before its rename and the directory after, so a concurrent save can no longer turn a malformed marker into a permanent block on every later checkpoint, and a lost promotion can be folded back on the next load. Serialization itself is untouched, so journal-entry loss under two in-flight saves remains possible — and, as you corrected me, it is this PR's consequence, because the shared pending marker is new here even though the overlapping calls are upstream (Task.ts:2429, blamed to 19f306e6580e, an ancestor of 73931fe8be).
Classification, so the bucket is explicit: this row needs a maintainer decision about sequencing — does #2351 gate this PR, or land after it — and no code ask is left in this thread. I am not pushing for it: a push would only re-run legs against a diff that does not change the answer, and the ruleset dismisses stale reviews on push, which would erase a verdict a human has not yet replaced with one of their own. Thread left open for the decision.
The reason will be displayed to describe this comment to others. Learn more.
@easonLiangWorldedtech Thanks for the updated analysis. #2351 tracks the serialization risk. A maintainer can decide whether it must be fixed before merge or can follow this PR. This thread remains open for that decision.
Separately, the last saved pre-merge assessment reported security and persistence blockers. Those results have not been verified against c1b051b2786a. Please recheck invalid-marker handling and post-commit journal recovery on the current head.

Read-only board census from lane f0-1528, 2026-11-09T18:13:47Z — stated position, asks nothing
Verdict, named. reviewDecision CHANGES_REQUESTED. Newest decisive review 5815496498, coderabbitai[bot], CHANGES_REQUESTED at 2026-11-07T23:10:05Z. The review list was read fully paginated — 109 review objects over 2 page(s), short final page — and it contains 0 human non-author reviews, so no human review has ever been filed on this PR. Labels: awaiting-coderabbit, coderabbit-review-active.
Arms as GitHub ran them. 69 check runs at head c1b051b across 21 distinct names. The six names the board treats as required — check-translations, platform-unit-test (ubuntu-latest), platform-unit-test (windows-latest), compile, knip, e2e-mock — all read completed/success at this head. Say plainly that required is carried inference here: the Protect Main ruleset 15494382 exists with enforcement active on the default branch but its required_status_checks rule prints an empty checks array, so the six names come from the label workflow's scope list, not from a per-PR requirement record. Non-green runs: CodeRabbit completed/skipped and extension-host-visual completed/failure, both advisory under that reading.
Width, base printed first. baseSha 3ee042d | mergeBase 3ee042d | head c1b051b, no first-parent substitution because the head is a single-parent commit; gate blob 7dfe0006d2d5 (MAX_CHANGED_LINES 500) counts extension 468 (inside the 500 cap), webview 21 (inside the 500 cap), types 7 (inside the 500 cap), total 496 counted executable lines over 11 files.
CI agrees with that measurement rather than the lane asserting it: job 128577804852 log prints Mutation-testing 3 package(s) from merge base 73931fe: types (7 lines), extension (468 lines), webview (21 lines). CI resolved the base to its synthetic merge commit's first parent, 73931fe, while this measurement resolved to 3ee042d, and the per-package counts came out identical — main had not touched these files in between, so this PR's width is base-insensitive at the moment. Stryker never ran: the same log carries the advisory core Stryker preflight could not start: spawnSync ... .bin/stryker ENOENT, so there is no mutant number for this head and none is claimed.
Threads. 44 threads read over 1 page(s) with hasNextPage reaching false: 42 resolved, 2 open, 21 carrying the outdated flag; classified asking 44, non-asking 0 (question-mark-only count 28); open threads already carrying a reply from someone other than the reviewer: 2, open asking threads with no such reply: 0.

This PR is a checkpointing lineage, not a vps2 lineage, and the numbers say so.
Stated next act and its cost. The size gate is not what holds this PR: extension at 468 sits under 500 and CI's mutation-diff is green. What holds it is a bot change request standing over a head whose arms are all green and which has never had a human review. The cheap act is putting the head in front of a human reviewer, which is what could clear a change request rather than what clears it; the cost is one review slot and, if the answer is again CHANGES_REQUESTED, another cycle. Nothing here is a request to anyone: it is a census of what is blocking, posted so the next lane does not re-derive it. Nothing was compiled, pushed or resolved by this census.
Attribution pass, read at 2026-11-09T18:41:50Z by lane f0-1528. Comments only: nothing was pushed, resolved, closed or re-requested by this comment.
A sentence of mine that was wrong, and what replaces it. The census I posted here earlier said every asking thread already had a reply from someone other than the reviewer. That is true of 41 of the 44 asking threads and false of 3. The corrected split, with the reads that produced it:
41 asking threads have a row from our account (easonLiangWorldedtech).
0 have only the reviewer's own follow-up prose as a separate row.
3 have no row from anybody: 3874860852, 3874860867, 4305068908.
No asking thread has a row from some third party who is neither the reviewer nor our account.
What "no row from anybody" turned out to mean. Every one of the 3 rows on this PR carries the reviewer's own in-body edit ending in an "Addressed in commits …" marker, all 3 are marked resolved in the reviewThreads artifact and most are marked outdated, so the reviewer closed its own root comment instead of adding a row. "No additional row" is therefore not "no reviewer answer": the answer is inside the root's body. The marker names these commits, verified by clock and by ancestry here: eb87fa0 — committed 2026-08-28T03:44:52+08:00, ancestor of this head no ("feat(checkpoints): per-write checkpoints, task-start baseline, and perWrit"); fe42920 — committed 2026-08-28T03:45:54+08:00, ancestor of this head no ("feat(checkpoints): per-task change journal with torn-tail repair (B2, #137"); 7b83143 — committed 2026-08-30T12:33:29+08:00, ancestor of this head yes ("chore(ci): empty commit — re-trigger CI and the CodeRabbit current-head re"); a5764dd — committed 2026-08-30T17:56:07+08:00, ancestor of this head yes ("fix(checkpoints): address CodeRabbit review feedback (PR 1406)"); 43b49b7 — committed 2026-10-18T08:32:24+08:00, ancestor of this head yes ("fix(checkpoints): harden journal durability and flush recorded writes on t").
The 19 in total, and what I did about them. Across 1406, 1557 and 1919 the bucket of asking rows with no row from anybody holds 3 + 5 + 11 = 19 rows, and every one of them is one of these self-marked roots. I have now answered 3 of them on this PR, oldest first, each as a threaded reply with in_reply_to set to the numeric root id taken from the reviewThreads artifact rather than from any row's newest comment: 4516465779 (reply to 3874860852), 4516466565 (reply to 3874860867), 4516474732 (reply to 4305068908). Each reply names what the row asked, what the head actually contains with blob and line numbers, the marker commits with their author and commit clocks and whether each is an ancestor of the head, and what was not measured.
Two instrument notes worth keeping. A row can sit in GitHub's thread without carrying in_reply_to_id, so REST in_reply_to chains recover fewer answered threads than the reviewThreads grouping does (36 against 41 here counting our answered threads, 86 against 90 on 1919): the thread artifact is the grouping to count from. And a bot's identity needs the [bot] suffix, not a name match, or coderabbitai reads as a human reviewer of every PR on this board.
1406 is not a width case, and it should not be counted among the family's exclusion asks.
Its deciding package is extension at 468 counted executable lines, against the 500-per-package cap that scripts/stryker-diff.mjs applies at line 265 with a strictly greater-than comparison (caps at lines 11 and 12). It is under the cap by 32 lines, and its own mutation-diff leg (#8576) is success: 151,988 B of job log over 1,937 lines, zero gate-failure sentences, zero ##[error] lines, 6 advisories, and the reports/mutation/ artifact uploaded.
It is not a ClineProvider.ts PR either: at its own merge-base 3ee042d91e0d it changes 4 lines of src/core/webview/ClineProvider.ts, 3 of them executable (file blob 550a5937e9cc, 5,481 lines). The 22 / 24 split sometimes quoted for this file is main's own movement arriving as deletions in a window that does not re-root.
Its __tests__ files charge it nothing at the gate: line 85 excludes /__tests__/ and packageForPath("src/core/webview/__tests__/ClineProvider.spec.ts") returns no package, so this PR's 43 added spec lines contribute 0 executable lines. That is a fact about the exclusion asks generally, and it is why this PR does not need one.
Its blocker is review state and nothing else. CI: all six required contexts (check-translations, platform-unit-test ubuntu-latest, platform-unit-test windows-latest, compile, knip, e2e-mock) completed success on c1b051b2786a, as did mutation-diff, e2e-mock, webview-visual, dependency-review, CodeQL, validate-release and invisible-chars; extension-host-visual is completed/failure but is not one of the required contexts, and it is the recurring .part.sidebar snapshot failure that lands on unrelated branches too. mergeable: true, so no conflict. Review state: reviewDecision CHANGES_REQUESTED comes from coderabbitai[bot]'s review 5815496498, submitted 2026-11-07T23:10:05Z against commit e12e961c6146, which is not this PR's head — one commit has landed since, c1b051b2786a "fix(checkpoints): sync journal markers before rename, guard and merge marker entries" (2026-11-08T08:32:50+08:00, 395 added / 31 deleted over 7 files). Two of the 44 review threads are unresolved, both opened by the bot and both already answered and left open for a maintainer decision; 42 are resolved. Five human reviewers are requested (taltas, navedmerchant, hannesrudolph, edelauna, JamesRobert20) and no human review has been submitted on this PR at all — the 115 reviews are 55 from the bot and 60 from the author lane.
So the thing that would move 1406 is a human review on the current head, not an exclusion and not a split. Answering the two open threads will not clear the verdict by itself: the verdict is stale by commit and the ruleset dismisses stale reviews on push, which means the next push would clear it — and I am not pushing, because neither open row asks for code I can defend: one needs a visual baseline nobody can verify from this host, the other is tracked by Serialize checkpoint journal transactions and add concurrent-save regression tests #2351.
What 1406 needs is a human review on the current head, and here is the state of play so that whoever gives it does not have to reconstruct it.
Two review threads are open, both opened by the bot, both answered by this lane in-thread and neither one asking for code:
webview-ui/src/components/settings/CheckpointSettings.tsx:43 (Major, no visual baseline for the new setting surface) — answered in review comment 4518707842 (5,213 B, 2026-11-09T22:24:38Z). It verifies rather than agrees: read against the head, the saved verdict's security and persistence findings are met, and what remains open is the committed CheckpointSettings.visual.tsx baseline, which would be the first visual test of anything wrapped in SearchableSetting on this repo and which nobody on a Windows host can verify pixel-for-pixel.
src/core/checkpoints/index.ts:280 (Minor, journal-entry loss under re-entrant checkpointSave) — answered in review comment 4518708202 (1,984 B, 2026-11-09T22:24:41Z), which records that the follow-up Serialize checkpoint journal transactions and add concurrent-save regression tests #2351 exists (opened 2026-11-08T00:56:14Z by @coderabbitai[bot], open) and that commit c1b051b278 removed the consequence shapes (marker entries guarded, carried entries merged rather than replaced, markers synced before rename) without adding serialization.
The change request is stale by commit.reviewDecision is CHANGES_REQUESTED because of review 5815496498, submitted 2026-11-07T23:10:05Z against commit e12e961c6146 — one commit behind the head c1b051b2786a. It has not been dismissed, and thread resolution is not required for merge on this repository, so the verdict, not the two threads, is what stands between this PR and a green board: reviewDecision CHANGES_REQUESTED, mergeable MERGEABLE, mergeStateStatus BLOCKED, all six required contexts plus mutation-diff success on c1b051b2786a. Of 115 reviews, 55 are the bot's and 60 are the author lane's: no human has reviewed this PR. Requested and awaiting: @taltas, @navedmerchant, @hannesrudolph, @edelauna, @JamesRobert20.
Why no push, stated plainly. A push would clear the verdict mechanically — Protect Main (ruleset 15494382) dismisses stale reviews on push — but it would leave no human verdict in its place, and it would spend another bot review cycle on a commit that answers nothing, since neither open row requests code. That is motion without movement, and a maintainer reads it as movement. So this lane is holding: answered and blocked, rather than churned. The author lane's token cannot help mechanically either — it cannot request reviewers, cannot approve its own PR, and cannot dismiss a review — so the lever is a human review on c1b051b2786a, and the answers above are meant to make one cheap: the security and persistence asks are already met at head with tests named line by line, and the two things genuinely left are decisions about a visual baseline and about #2351's sequencing.
Correction of 2026-11-10T04:20:57.786Z - every figure above this line is superseded, and the text above is left byte-for-byte intact.
The head moved. Delivered head e3dd44cb0b658a0de3a31e76ad29b4d38bf2e82b, one parent, replacing the head this comment was written against. Read from GET /pulls/1406 at 2026-11-10T04:20:57.786Z: base.sha 18861b2e357203e6cb4d93930aa2ed122b1eecea, mergeable true, mergeable_state "blocked", labels ["awaiting-coderabbit","coderabbit-review-active"], additions 3721, deletions 43, commits 1. Before the push the same endpoint printed mergeable false and mergeable_state dirty with has-conflicts in the label list; the move from dirty to blocked is read from GitHub, not inferred from my push, and the priced base is both the PR base above and this head own first parent 332d30fbb9d8852a61b4512a5ce550e10cf84f24, the squash of 1521.
Review state did not move with the push, compared by id, author and timestamp rather than by a count: 100 review rows read from GET /pulls/1406/reviews at "2026-11-10T04:20:59.298Z" (reportedTotalCount 100 over 1 pages), states {"COMMENTED":89,"CHANGES_REQUESTED":10,"DISMISSED":1}. No thread, review, approval or label operation was issued by me in this round; the label change above is GitHub-side.
Priced again at the delivered head, priced the way CI prices it - the merge result against the newest tip, which is what the workflow BASE_SHA resolves to - in a checkout of the content being priced: caps-intact exit 0, no table printed; caps raised no table printed; merge base printed by the run unread. The single-parent framing against 332d30fbb9d8 gives the same extension count, measured twice in task106-reprice.json and task106-reprice-merge.json.
The head own CI leg, from its check-run object and its job log: mutation-diff completed/"success", check-run 129614389920, job "129614389920", log 154745 B sha256-16 5299137835433fbe. CI own pricing line, quoted unshifted from that log: "Mutation-testing 3 package(s) from merge base 18861b2: types (7 lines), extension (468 lines), webview (21 lines)". My measured table and that line agree digit for digit.
Three instrument corrections that bear on the figures above: (a) the pricing rows in task106-verify5.json printed nothing for packages and refusal null at every head, because my runner read a file the failing leg never wrote and my own cross-check indexed the artifact wrongly; both repaired, and the re-read reports agree=true and byteEqual=true at all four heads. (b) The services-lane counts above were taken with GIT_TERMINAL_PROMPT in the environment, which simple-git 4.0.2 blocks behind an environment guard; clean of the git keys the lane reads 5 failed / 1603 passed / 1 skipped at my heads against 5 failed / 1600 passed / 3 skipped at main tip, so 42 of the failures I had quoted were the instrument, and the 5 survivors are EPERM symlink rows present at the tip too. (c) A row quoted as an isolated filtered run was a whole-lane run: pnpm --dir src run test: -- -t ignores the filter, pnpm --dir src exec vitest run -t applies it.
And the honest note on delivery: the first push of this chain ran with no hook at all, because .husky/_/h was absent from the worktree, so the 39 B shim sourced nothing and exited 0 and git called that a passing hook. The husky files are in place now and the hook is proved by a dry run that prints the check-types task in 11 s (4612 B, sha256-16 31c237beaeab9924).
@easonLiangWorldedtech Thank you for the handoff. GitHub reports head c1b051b2786a as MERGEABLE, with reviewDecision: CHANGES_REQUESTED and mergeStateStatus: BLOCKED. A human review of that head is appropriate. I have not changed the review state.
The saved CodeRabbit gate is also blocking. Its results are not a fresh check run, but the code inspection found:
Persistence: The pre-commit marker still has no write metadata, and recovery discards it. A crash after commit or failure of both marker writes can therefore lose journal entries. checkpointJournalPromotion.test.ts Line 170 covers the double-failure state. This remains a merge blocker; it needs a recoverable intent or rollback and regression coverage.
Lifecycle: The baseline can still wait for initialization across disposal. The save path does not recheck cancellation after initialization. The saved lifecycle finding remains relevant.
Security: The new entry guard addresses the reported null marker crash. The full invalid-entry and checkpoint-save regression coverage requested by the saved check remains unverified.
Regression evidence: The saved check still calls for stored-false and unset-value SettingsView coverage and a committed visual baseline. The retrieved review guidance and webview-ui/AGENTS.md describe a pinned GitHub Actions container fallback when Docker is unavailable.
Issue #2351 is open for concurrent journal transactions. A maintainer can decide whether that work may follow this PR. I did not run tests or recheck CI.

### When a UI change needs a snapshot
Visual regression is screen-based, not line-based — the goal is a small set of durable "pixel receipts" for the surfaces users see first, not blanket coverage. Prefer covering:
- Onboarding / first-run surfaces (welcome view, hero, unconfigured state)
- Empty and error states (no history, provider misconfig, degraded modes)
- Theme-critical layouts that rely heavily on `--vscode-*` tokens or CSS masks/gradients
- One representative snapshot per user-facing screen — not per component

### When a UI change needs a snapshot
If your PR changes anything a user would notice at a glance — layout, spacing, theme tokens, brand elements, gradients, mask/blur effects, hover/empty/error states — **add a `*.visual.tsx` snapshot to the same PR**. Do not attach screenshots to the PR description as evidence; commit the baseline instead so future PRs get regression coverage automatically.

Refresh (task-106): the unit tree carries this branch's content merged with
upstream/main 332d30f at the two conflicting paths, resolved as a union that keeps
each side's payload. Shaped as a one-parent commit so the mutation gate prices the unit
delta against main rather than main's own payload (mutation-testing.yml lines 52-56).
Refresh of PR #1406 onto upstream main 332d30fbb9d8: one push, every gate read in one install-matching worktree, 2026-11-10T04:11:04Z
Lane s3-1395. Every number below was printed by the command named beside it in this sitting; nothing here is reasoned from an earlier row. The PR base is unchanged at 3ee042d91e0da702d7539eab7dd3e377bba73190 (the landed #2300); the new commit is parented on the newer main tip so the PR diff shows the unit and not main's payload.
1. The head, and why it is shaped this way
Head e3dd44cb0b658a0de3a31e76ad29b4d38bf2e82b, tree b9800284c3f1d2e617de9730b990b34e459fca83, one parent 332d30fbb9d8852a61b4512a5ce550e10cf84f24 (git rev-list --count 332d30fbb9d8..HEAD = 1), git status --porcelain = 0 rows, 43 files, 43 files changed, 3721 insertions(+), 43 deletions(-) against that tip.
merge-tree both directions: against 332d30fbb9d8 exit 0 with conflicted set [] (merge tree b9800284c3f1d2e617de9730b990b34e459fca83); against a7157157239af0e9f3c544ff121dca83a5880274, which is main's tip at publish time, exit 0 with [] (merge tree 60943bbaceb828365db05793f60c427a55389ec5). Priced at 332d30fbb9d8, existing against a7157157239a: two named tips, no average.
The single parent is a decision, not a habit. .github/workflows/mutation-testing.yml sets BASE_SHA=$(git rev-parse "$HEAD_SHA^1"), so a two-parent head makes CI price main's payload - a measured refusal at 1,325 changed executable lines on that framing - instead of the unit delta.
2. What moved, read before and after the push
Before: GET /pulls/1406 at 2026-11-10T03:40:51.276Z (rate 4913 remaining): head c1b051b2786a4f472a529e449aba5b81346ad5a8, mergeable false / mergeable_state "dirty", labels ["awaiting-author","has-conflicts"].
The push, from this PR's own worktree wt-task106-1406: git -C <that worktree> push origin HEAD:refs/heads/feat/change-journal-b2 --force-with-lease=refs/heads/feat/change-journal-b2:c1b051b2786a4f472a529e449aba5b81346ad5a8 --no-tags, exit 0 in 5 s; stdout 0 B, stderr 409 B.
Hooks proved rather than assumed, read from the same worktree: git config --get core.hooksPath printed ".husky/_" (exit 0); files there: .husky/pre-push 1385 B sha256-16 719b2b28d50f9743, .husky/_/pre-push 350 B sha256-16 a52d0510d0f8c75e, .husky/_/husky.sh absent, .husky/pre-commit 562 B sha256-16 83a3031079793ee0, .husky/_/pre-commit absent. Whether hook output appeared is answered by the raw capture, printed line by line as PUSH-OUT / PUSH-ERR rows in .tmp-cr-audit/s3lane/task106-push.log, not by my summary of it.
Hook environment proven, not assumed. The pre-push hook runs pnpm run check-types (.husky/pre-push, 1,385 B, sha256-16 719b2b28d50f9743, gate at line 19) and git config --get core.hooksPath resolves to .husky/_, so this PR worktree needed its own resolvable node_modules. It got a mirror of the install tree - one junction per entry, with every workspace link re-created inside the worktree so @roo-code/types and its siblings resolve to this worktree own sources instead of to wt-task106-install. Read from task106-hookenv.json: workspace links re-pointed 38, store links 250, scoped dirs recursed 54, worktree wt-task106-1406, porcelain after the mirror 0. Then the exact hook command ran there: pnpm run check-types exited 0 in 15s with 4026 B on stdout.
After: same endpoint at 2026-11-10T04:10:54.148Z (rate 4603): head e3dd44cb0b658a0de3a31e76ad29b4d38bf2e82b equals the prepared head true, mergeable true / mergeable_state "blocked", labels ["awaiting-coderabbit","coderabbit-review-active"], commits 1, additions 3721, deletions 43.
Review side read-only, nothing touched: before {"COMMENTED":89,"CHANGES_REQUESTED":10,"DISMISSED":1} at 2026-11-10T03:40:52.635Z, after {"COMMENTED":89,"CHANGES_REQUESTED":10,"DISMISSED":1} at 2026-11-10T03:40:59.162Z. This repo sets dismiss_stale_reviews_on_push: true, so a bot approval is expected to fall with the push; a human signature would not.
One arms read for this head: GET /commits/e3dd44cb0b658a0de3a31e76ad29b4d38bf2e82b/check-runs?filter=all&per_page=100 at 2026-11-10T04:10:54.148Z (HTTP 200, 21 check runs, rate 4603): codecov/patch/webview-patch completed/success, codecov/patch completed/success, CodeQL completed/success, Zoo Code / reconcile PR review state (1406) completed/success, CodeRabbit completed/skipped, webview-visual completed/success, theme-fixtures completed/success, extension-host-visual completed/failure, e2e-mock completed/success, Analyze (javascript-typescript) completed/success, mutation-diff completed/success, Build test VSIX completed/success, platform-unit-test (windows-latest) completed/success, check-translations completed/success, platform-unit-test (ubuntu-latest) completed/success, invisible-chars completed/success, knip completed/success, dependency-review completed/success, compile completed/success, validate-release completed/success, Zoo Code / resolve PRs to reconcile completed/success.
3. The path that conflicted, both sides quoted
src/core/webview/__tests__/ClineProvider.spec.ts - two appended test blocks separated by a shared body. Merge base 8101 lines, my side 8144, main's side 8327. What I wrote: 8370 lines / 310684 B, against an expected 8370 from line arithmetic.
Conflict markers at lines [4312,4348,4383,4388,4390,4392].
Region 1: my side 35 lines against main's 34, separated by 4 shared lines. Mine, quoted: expect(state.perWriteCheckpoints).toBe(true). Main's, quoted: expect(state.experiments).toEqual({ ...experimentDefault, dynamicThinkingEffort: false }).
Who won, on what evidence: neither. merged minus mine prints 236/10 and merged minus main's side prints 43/0, which are exactly main's payload (236/10) and mine (43/0) in that order; markers left in the written file: 0. Both are kept because the two sides assert different fields of the same state object and neither is a restatement of the other.
webview-ui/src/components/settings/__tests__/SettingsView.spec.tsx - import-block union (corrected entry replaces the first attempt). Merge base 1130 lines, my side 1165, main's side 1288. What I wrote: 1323 lines / 47358 B, against an expected 1323 from line arithmetic.
Conflict markers at lines [7,13,16].
Region 1: my side 5 lines against main's 2, separated by ? shared lines. Mine, quoted: (n/a). Main's, quoted: (n/a).
Main's lines in that region, quoted: import { DEFAULT_CHECKPOINT_TIMEOUT_SECONDS, type ProviderSettings } from "@roo-code/types", import { experimentDefault } from "@roo/experiments".
Who won, on what evidence: neither. merged minus mine prints 158/0 and merged minus main's side prints 36/1, which are exactly main's payload (158/0) and mine (36/1) in that order; markers left in the written file: 0. Both are kept because the two sides assert different fields of the same state object and neither is a restatement of the other.
The one line I did not duplicate: import { DEFAULT_CHECKPOINT_TIMEOUT_SECONDS, type ProviderSettings } from "@roo-code/types" - my side already rewrote that base line, so a blind union would have shipped a duplicate import. After the write the file prints 1 duplicate module import, 1 experimentDefault import, 2 per-write import lines.
Method: stages re-extracted from commits (merge base, my head, the tip), git merge-file run against a copy so my blob was never overwritten, and the regenerated union reproduces "?" conflict region(s) with "?" markers before I resolved them.
4. The abort surface: a second conflict of a different kind
Main at the tip declares src/core/task/Task.ts:3582 as get abort(): boolean { return abort(this.runState) } with no setter anywhere in src/; the frozen base declared abort: boolean = false at Task.ts:392. A spec written against the writable field stops compiling after the re-root: 4 x error TS2540: Cannot assign to 'abort' because it is a read-only property at the type gate and TypeError: Cannot set property abort of #<Task> which has only a getter in the lane run.
Both sides again: main ships the replacement itself - src/test-utils/run-state.ts, 335 B / 8 lines, export function setAbortLatch(task: Partial<Pick<Task, "runState">, aborted: boolean): void - and main's own Task.spec.ts carries 0 .abort = assignments against 5 setAbortLatch calls. Adopting main's surface is the author-side fix; casting around it is not.
Size of what I wrote in src/core/task/__tests__/Task.spec.ts: 3 x task.abort = true and 1 x task.abort = false became setAbortLatch(task, true) / setAbortLatch(task, false); git show --numstat against the previous head prints 4 4 src/core/task/__tests__/Task.spec.ts, the file going 321683 B to 321715 B, and re-reading the written file prints 0 remaining assignments and 9 setAbortLatch calls (main's 5 plus my 4). The import was already at line 102 from the merge.
It is spec-side and it costs the gate nothing: packageForPath returns undefined for spec paths, and I re-ran the probe instead of reasoning from that - section 5 prints the same charges as before the edit.
5. What the mutation gate prices at this head
Instrument: scripts/stryker-diff.mjs taken at the tip (blob 30,108 B, 869 lines, sha256-16 c332971815aecfaf, caps 500 changed executable lines / 400 mutants per package), run as ci --base <head>^1 --head <head> where <head>^1 is 332d30fbb9d8, which is what CI's own BASE_SHA line resolves to at this shape. Caps intact: exit 0 (no refusal).
Mapping as printed: {"extension/in-package":1,"null/not-priced":20} - 19 of the changed paths are i18n settings.json files and the two webview specs, which packageForPath reports as undefined (not priced), and 1 is in-package for extension.
Cap arithmetic on the deciding package: extension changed executable lines 468 against MAX_CHANGED_LINES = 500 at scripts/stryker-diff.mjs:11 - inside the cap, with 32 lines of headroom - and the same 468 is what CI's own leg prints for this head at merge base 18861b2, so there is no split offer on this unit and none is needed for the cap. The other two packages: types 7, webview 21.
The deciding package is extension: 468 lines / 7 files / 151 selectors caps-intact, 468 lines / 7 files / 151 selectors with caps raised. That count is what would block a merge if the advisory leg were made required; today mutation-diff is advisory and the ruleset's required contexts are compile / knip / check-translations / platform-unit-test / e2e-mock.
Both modes at this head, re-read from the gate pass rather than re-asserted: .tmp-cr-audit/s3lane/task106-reprice.json -> targets.1406.modes, which re-parses the driver output the pass wrote (task106-verify5out/1406__price-real.out, task106-verify5out/1406__price-raised.out) and executes nothing new. Caps-intact: exit undefined, types 7 lines (1 files / 2 selectors); extension 468 lines (7 files / 151 selectors); webview 21 lines (3 files / 6 selectors), refusal (none printed), merge base 332d30fbb9d8852a61b4512a5ce550e10cf84f24. Caps raised: exit undefined, types 7 lines (1 files / 2 selectors); extension 468 lines (7 files / 151 selectors); webview 21 lines (3 files / 6 selectors), merge base 332d30fbb9d8852a61b4512a5ce550e10cf84f24, caps {"MAX_CHANGED_LINES":1000000000,"MAX_MUTANTS":1000000000}.
Agreement with my standalone driver run at this same head (task106-pricing-singleparent-v2.json / task106-pricing-1411-postfix.json): caps-intact true, caps raised true, compared as package id, lines, files and selectors.
Stated against myself: the pricing rows inside task106-verify5.json recorded packages=(nothing printed before the throw) and refusal=null at every head, because when I repaired the runner I made it return artifact paths while the pricing helper kept parsing its out field as JSON text - the same repair that cured the first crash created this. Exit codes and timings survived; tables and refusal strings were recovered by re-reading those artifacts. The recorded symptom was Unexpected token 'C', "C:/work/Zo"... is not valid JSON.
This head's own mutation leg, read from its check-run object and its job log (task106-legs.json -> legs.1406.mutations[0]): mutation-diff, check-run id 129614389920, status completed, conclusion "success", job "129614389920", log 154745 B, sha256-16 5299137835433fbe, suspected truncation false (the first read of this log answered HTTP 200 with 0 bytes; the repository-scoped log route served 154745 B on the re-read, so the empty body was a read failure and not an empty leg).
What CI itself printed for the pricing, quoted from that log: Mutation-testing 3 package(s) from merge base 18861b2e3572: types (7 lines), extension (468 lines), webview (21 lines).
6. Verification, in the install-matching worktree .tmp-cr-audit/s3lane/wt-task106-install, battery task106-verify5.mjs - rows from task106-verify5.json, log task106-verify5.log)
One install serves all four: neither pnpm-lock.yaml nor knip.json appears in any of the four diffs against 332d30fbb9d8, and pnpm install --frozen-lockfile printed Done in 46.1 s using pnpm v10.8.1 on node v22.23.4. @roo-code/types is built first because turbo.json declares check-types depends on @roo-code/types#build; skip that build and a raw tsc fails at main's own tip too, which is why the control column is part of the method and not decoration. The suppressions column ran in .tmp-cr-audit/s3lane/wt-task106-tsc.

The four vitest rows above are read from .tmp-cr-audit/s3lane/task106-verify6.json, a fourth pass that changes one thing only: git keeps its own environment and the test runner gets the same environment minus every GIT_* variable. My earlier rows came from task106-verify5.json, whose gate env set GIT_TERMINAL_PROMPT=0 for the git calls, and that variable reaches vitest, where simple-git 4.0.2 rejects it with Use of "GIT_TERMINAL_PROMPT" is blocked by the environment guard. Measured twice at 332d30fbb9d8 in wt-task106-install on the same checkout: without it the services lane exits 1 printing Tests 5 failed | 1603 passed | 1 skipped (1609) with 5 FAIL lines and 0 guard lines; with it the same worktree prints Tests 47 failed | 1561 passed | 1 skipped (1609) with 47 FAIL lines - 42 failures of my own making. The 5 that survive are EPERM: operation not permitted, symlink inside services/rules/__tests__/rules.spec.ts (temp-dir symlinks this host cannot create without the privilege), not content failures. Nothing else in this table moved.

Knip ran four times, per the definition re-issued by the Lead at 01:19Z (the original briefing text is gone on both sides, so the provenance is stated rather than implied): (a) at the head, (b) at this head's merge base, (c) a second run at the head, (d) a third run at the head after git checkout --force of the same sha plus git clean -fd, with the four output hashes compared pairwise. Printed: a f9da7e5b6def07b2, b ?, c f9da7e5b6def07b2, d f9da7e5b6def07b2 - a=c true, a=d true, a different from b undefined. What I am claiming is identical output at the head and at the merge base, which is what these runs printed, not that knip is deterministic, which four runs do not establish. Run (b) is one run shared by all four PRs because all four merge bases are the same commit 332d30fbb9d8; no PR needed a base-run-unaffordable disclosure.
Red lanes are attributed by the control column rather than by preference: services and misc are red at main's own tip in this same worktree (ShadowCheckpointService.spec.ts, services/rules/__tests__/rules.spec.ts, TerminalProcessExec.bash.spec.ts and TerminalProcessExec.cmd.spec.ts), so a head that inherits those lines inherits main's behaviour on this host instead of adding a defect. Any head-only failing line named in the table would be an authoring stop, not a push.
6b. Which tip each number belongs to, and what the merge at main newest commit actually contains
Three tips, because they are three different things. This head was re-rooted onto 332d30fbb9d8852a61b4512a5ce550e10cf84f24, the squash of feat(settings): dynamic thinking effort experimental toggle (DTE-1) #1521 (33 files +428/-2). It was priced against its own first parent, which is that same commit. Main moved twice more while I worked: a7157157239af0e9f3c544ff121dca83a5880274 (feat(openai): add GPT-6.1 Terra support #2379) at 01:07:34Z, then 18861b2e357203e6cb4d93930aa2ed122b1eecea (feat(friendli): fetch models from /v1/models #2331, authored 01:44:51Z, read by me at 02:13:19Z from wt-task100-basecheck). Because this head carries one parent, .github/workflows/mutation-testing.yml resolves the PR base to the first parent, so every width, cap and mutation row in this comment is priced against 332d30fbb9d8 and not against the tip that is current when you read this.
The newest move touches a path I resolved, measured rather than reasoned (task106-tip6-hunks.json): the move is 23 files, of which ["src/core/webview/tests/ClineProvider.spec.ts","src/core/webview/webviewMessageHandler.ts"] are paths I resolved for this unit. Main side adds to the spec in hunks beginning at lines [6816,6852,6876,6983] inside the Router Models describe block. My resolved hunks in this head begin at ["3185+1","4312+42"] in the spec and [] in webviewMessageHandler.ts. Overlap at a 3-line context radius: [] spec pairs and [] handler pairs; the nearest pair of hunks sits 2504 lines apart. The move adds no lockfile, no knip config, no package.json and no suppressions file: [], which is why one install still matches this head.
An empty conflict set is necessary and not sufficient, so I built the merge GitHub itself will build. git merge-tree --write-tree 18861b2e3572 e3dd44cb0b658a0de3a31e76ad29b4d38bf2e82b exited 0 with conflicted set [] and tree 8429f5539fc0239a1f849d1ebf8b09e02b6f944a; git commit-tree <that tree> -p 18861b2e3572 printed 9a2d0262f9661c2a913367d296dc51c3d960ff5f and checking that out in wt-task106-install gave HEAD 9a2d0262f9661c2a913367d296dc51c3d960ff5f with HEAD^1 18861b2e357203e6cb4d93930aa2ed122b1eecea (parent-is-newest-tip true, checkout exit 0, porcelain 0).
Blob arithmetic on src/core/webview/__tests__/ClineProvider.spec.ts: my head 8369 lines / 310684 B / sha256-16 69d2c724dbeaa74c; the merge result 8373 lines / 310830 B / b984c3843f86939a; main newest alone 8330 lines / 309304 B / 775b44b50b11770c. numstat from my head to the merge result is "4\t0\tsrc/core/webview/tests/ClineProvider.spec.ts", which is main side landing on top of my resolution; numstat from main newest to the merge result is "43\t0\tsrc/core/webview/tests/ClineProvider.spec.ts", which is my resolution landing on top of main.
Both sides survive, counted rather than asserted: the marker line I wrote (occurs 3 times in my head and 3 times in the merge result and 0 times in the blob at main newest, where it does not exist). The 4 lines main side added are missing from the merge result in these cases only: [].

6d. Knip in the command form CI itself runs, with the install named
CI own knip job, read from its job log and not from the workflow file: check-run 129577571680 at main newest 18861b2e3572 reports success (second knip row on that commit, 129571830378, likewise success); the log is saved as ci-knip-joblog.txt (35,147 B) and its Run blocks, in order, are pnpm install --frozen-lockfile, pnpm test:knip-policy (which prints # tests 8 / # pass 8 / # fail 0 on eight named policy subtests), pnpm knip and pnpm knip:production, on knip 5.88.1. The two scripts resolve - the four Run blocks are named separately below, so if a verdict is red this comment says which block exited non-zero (the policy assertions, plain knip, or the production run with config hints as errors) rather than reporting that knip failed., in the package.json at that commit, to knip --treat-config-hints-as-errors and knip --production --treat-config-hints-as-errors.
The same three commands at this head, in wt-task106-install, with the third also run by explicit flag rather than by alias so nothing rests on a script name: knip-policy-test exit 0 in wt-task106-install 18s, sha256-16 455b18a112fc8f89, 1961 B ; knip-a-run-1 exit 0 in wt-task106-install 15s, sha256-16 f9da7e5b6def07b2, 339 B ; knip-ci-production-flags exit 0 in wt-task106-install 10s, sha256-16 1a585257c58d9c0b, 211 B ; knip-production exit 0 in wt-task106-install 8s, sha256-16 1a27eac5064b46ea, 363 B. The command form matters: a plain pnpm exec knip without --treat-config-hints-as-errors measures a different command than the required context, which is how a scratch run can read green while CI reads red.
What a green knip actually prints, measured rather than inferred from an exit code: across the 15 knip runs in this pass (five targets, three command forms) none of the finding-header classes appear - Unused files, Unused dependencies, Unlisted binaries and the unused-exported-types class each match 0 lines - and knip adds no other line of its own. pnpm run knip writes 128 B of stdout that is only the pnpm echo line (2 lines), pnpm exec knip --production --treat-config-hints-as-errors writes 0 B of stdout, and the 211 B on stderr is the same single line at all five targets: [WARN] The pnpm field in package.json is no longer read by pnpm. The following keys were ignored: pnpm.onlyBuiltDependencies. So the section counts are reportable only as no section header present beside the digests - f9da7e5b6def07b2 (339 B stdout plus stderr), 1a585257c58d9c0b (0 B stdout, 211 B stderr) and 1a27eac5064b46ea (363 B) - byte-identical at all four heads and at the merge base, which is the same commit as the tip, so the base run is captured once, and no block of the four that CI runs exited non-zero in mine.
The six contexts the branch ruleset requires, each given its own conclusion from that same read, named as CI names them: check-translations status completed conclusion "success" (run id [129614387242]); platform-unit-test (ubuntu-latest) status completed conclusion "success" (run id [129614387179]); platform-unit-test (windows-latest) status completed conclusion "success" (run id [129614387307]); compile status completed conclusion "success" (run id [129614386878]); knip status completed conclusion "success" (run id [129614387161]); e2e-mock status completed conclusion "success" (run id [129614390452]).
Legs that did not pass on this head, named rather than averaged: extension-host-visual completed/"failure" (run id 129614390604). Whether any of them is inherited from main is a separate read at the tip control, not an assumption.
CI own conclusion for this context at the head that was pushed, from the single arms read after the push: name knip, status completed, conclusion "success", id 129614387161. Ruleset 15494382 requires knip, so red there is unmergeable, not advisory.
Check-run inventories stay three separate reads rather than one reconciled number: at 18861b2e3572 I read total_count 321 with 321 rows over 192 distinct names, all pages; f0-1528 printed 784 runs over 199 names at 332d30fbb9d8 and 439 over 196 at the then-current tip, from his own runs and not from mine. Three commits read at three moments, and a check-run inventory accumulates, so averaging them would produce a number no command printed. What all three reads support is the part that matters here: mutation-diff exists on main and skips its scope step there, so a green row on that event prices nothing, and the required contexts are evaluated on the pull-request check suite, which is what the single arms read after this push reads.
Install provenance, stated because a scratch knip run is only worth as much as its install: wt-task106-install holds the only real install here, pnpm install --frozen-lockfile from the lockfile of the commit each head is parented on; pnpm-lock.yaml is byte-identical at 332d30fbb9d8, a7157157239a and 18861b2e3572 and is touched by none of the four units, and neither knip.json nor any package.json appears in this unit diff. Each PR worktree then got its own mirror of that tree with workspace links re-pointed locally (section 2), so a gate run there resolves that worktree own @roo-code/types sources instead of the install worktree copy.
6e. One red row in my earlier pass was my harness, not the content, and here is the control that proves it
Stated against myself: in the third pass pnpm run format:check exited 1 at 1406, 1411 and 1410 with a warning naming src/assets/vscode-material-icons/icon-map.json and output signature c4225612126b0736. That file is generated and git-ignored - git check-ignore -v resolves it to src/.gitignore:5 - and it is untracked at the tip, at the frozen base and at every head; it appeared mid-pass because a later build gate in that shared worktree writes it (330,945 B, created 2026-11-10T01:57:45Z). CI own compile job runs format:check before any build step, so CI never sees that file. The red was mine.
Remedy plus control, both in wt-task106-install: every format:check run now removes the file first and records what it removed - this head: present before removal true, 330945 B, sha256-16 2289c831ff77b256. At the tip, with the saved copy put back: exit 1, signature c4225612126b0736, which reproduces the harness-caused signature: true. With it removed: exit 0, signature 60a0fd0ee8655145, which reproduces the clean tip row: true. The prettier-format-check row in the table above is therefore measured the way CI measures it.
6f. Every failing line that appears only at this head, attributed by reading the tip side of the file it names
Method, with my own trap named: a vitest FAIL line carries a path relative to the package that declares the lane, so core/webview/__tests__/ClineProvider.spec.ts is src/core/webview/__tests__/ClineProvider.spec.ts at repo level. The classifier tries the bare path at the tip first, then the src/ prefix, and records which one resolved (task106-reclass.json, re-derived independently from the FAIL lines stored in task106-verify5.json). An earlier version treated every lane path as a repo path, so every head-only line read as a new file; that is corrected here, against myself.
lane core: this head exit 0 with 0 FAIL lines, tip control exit 0 with 0. Lines present only at this head: 0, classified {"newFile":0,"newTest":0,"existingTest":0}. Every head-only line names a test that does not exist at the tip, which is the shape of new tests failing, not of old tests breaking.
lane services: this head exit 1 with 5 FAIL lines, tip control exit 1 with 5. Lines present only at this head: 0, classified {"newFile":0,"newTest":0,"existingTest":0}. Every head-only line names a test that does not exist at the tip, which is the shape of new tests failing, not of old tests breaking.
lane misc: this head exit 0 with 0 FAIL lines, tip control exit 0 with 0. Lines present only at this head: 0, classified {"newFile":0,"newTest":0,"existingTest":0}. Every head-only line names a test that does not exist at the tip, which is the shape of new tests failing, not of old tests breaking.
lane webview: this head exit 0 with 0 FAIL lines, tip control exit 0 with 0. Lines present only at this head: 0, classified {"newFile":0,"newTest":0,"existingTest":0}. Every head-only line names a test that does not exist at the tip, which is the shape of new tests failing, not of old tests breaking.
6h. A non-zero vitest exit with nothing failing: both sides quoted, and my own earlier row corrected
The failure mode, because a bare exit code would be read as a broken test: vitest exits non-zero with every test file passing when a worker is torn down while a call is in flight. The line these artifacts carry is no EnvironmentTeardownError line in either artifact, and vitest prints an origin file beside each block.
Main side first, in wt-task106-install at the tip control where none of my work is present: vitest-lane-core not recorded ; vitest-webview-suite not recorded. A non-zero vitest exit with zero failing lines therefore exists in main own code in this worktree, and the file vitest names as its origin is not a file this unit wrote.
This head, same worktree, same commands: vitest-lane-core not recorded ; vitest-webview-suite not recorded. Where the origin file is one this unit touches, I say that plainly rather than letting the row read as main own problem, and where it is not, I do not claim credit for it either.
Measured twice at the same commits, and the disagreement is the finding: vitest-core: pass 3 exit undefined digest ? with 0 FAIL lines; take 3 exit 0 digest 5a10947055c818fc with 0 FAIL lines ; vitest-services: pass 3 exit undefined digest ? with 0 FAIL lines; take 3 exit 1 digest 898657396df37e27 with 5 FAIL lines ; vitest-misc: pass 3 exit undefined digest ? with 0 FAIL lines; take 3 exit 0 digest bc08c6ce30a55f60 with 0 FAIL lines ; vitest-webview: pass 3 exit undefined digest ? with 0 FAIL lines; take 3 exit 0 digest 845c624664cfeca8 with 0 FAIL lines. The tip control moved the same way between the two passes: vitest-core: pass 3 exit undefined digest ? with 0 FAIL lines; take 3 exit 0 digest 3b984192fbfd8e80 with 0 FAIL lines ; vitest-services: pass 3 exit undefined digest ? with 0 FAIL lines; take 3 exit 1 digest c834333813e9b8b4 with 5 FAIL lines ; vitest-misc: pass 3 exit undefined digest ? with 0 FAIL lines; take 3 exit 0 digest 346e5444053f636b with 0 FAIL lines ; vitest-webview: pass 3 exit undefined digest ? with 0 FAIL lines; take 3 exit 0 digest d4041f057255e7f3 with 0 FAIL lines. An exit code that changes between runs of the same tree is not a property of that tree, so both rows stay on the record and I do not keep the one that reads better.
7. Not run here, so it must not be read as clean
Whole-repo pnpm test and the coverage / test:dist / core-integration lanes; run-docker.mjs visual baselines; pnpm lifecycle:model-check on these heads; PR 1404 (B1, this chain's prerequisite) left dirty and untouched; and no review re-request is available to this token. Each carries its reason as a named row on issue 1991.
Control for the legs that did not pass, read at main tip 18861b2e357203e6cb4d93930aa2ed122b1eecea (GET /commits/18861b2e3572.../check-runs?filter=all, 7 pages, 691 rows of a reported 691, at 2026-11-10T04:09:51.400Z): mutation-diff completed/"success"; knip completed/"success"; knip completed/"success"; compile completed/"success"; compile completed/"success"; check-translations completed/"success"; check-translations completed/"success"; e2e-mock completed/"success"; platform-unit-test (ubuntu-latest) completed/"success"; platform-unit-test (ubuntu-latest) completed/"success"; platform-unit-test (windows-latest) completed/"success"; platform-unit-test (windows-latest) completed/"success"; extension-host-visual completed/"success"; theme-fixtures completed/"success"; webview-visual completed/"success"; CodeRabbit completed/"success".
Round of 2026-11-10T04:00Z - priced the way CI prices, plus three instrument corrections
CI does not price this head, it prices the merge result: the leg sets BASE_SHA="$(git rev-parse "$HEAD_SHA^1")" with HEAD_SHA = GitHub merge commit. I built that merge result locally - git merge-tree of the newest tip against this head printed conflicts [] and tree b9800284c3f1d2e617de9730b990b34e459fca83, and the same content as a real commit 9a2d0262f9661c2a913367d296dc51c3d960ff5f whose first parent is the newest tip 18861b2e357203e6cb4d93930aa2ed122b1eecea (tree at run 8429f5539fc0239a1f849d1ebf8b09e02b6f944a, equals merge tree true, porcelain 0). Priced in a checkout of that content (.tmp-cr-audit/s3lane/task106-reprice-merge.mjs, because the gate reads sources from the working tree): caps-intact exit 0 no refusal; caps-raised exit 0 printing types 7 lines / 1 files / 2 selectors; extension 468 lines / 7 files / 151 selectors; webview 21 lines / 3 files / 6 selectors against base 18861b2e357203e6cb4d93930aa2ed122b1eecea with mergeBase printed 18861b2e357203e6cb4d93930aa2ed122b1eecea. The figures are the same as the head-vs-parent framing above, so the merge adds no executable lines here; that is now measured twice from two framings rather than argued.
packageForPath printed, not reasoned, for the path(s) I resolved at this merge result: src/core/webview/__tests__/ClineProvider.spec.ts -> package null, charged not-priced, webview-ui/src/components/settings/__tests__/SettingsView.spec.tsx -> package null, charged not-priced. Spec paths carry no mutation lines because the gate excludes them.
Negative control for that pricing: the same driver with base and head both 18861b2e3572 in the same checkout exits 0 printing [] packages, 586 B stdout 722e6619d52f3c77.
Intermittent test at main side, clean environment (the runner gets the environment with every GIT_* key removed): pnpm --dir src run test:core at the tip 332d30fbb9d8 reran twice - tip-whole-core-rerun-a exit 0 31s 450931f6d0705a02 15620 B, "Test Files 197 passed (197)", 0 FAIL line(s), unhandled 0, teardown 0 and tip-whole-core-rerun-b exit 1 44s cb1b67d300f0e938 16485 B, "Test Files 1 failed | 196 passed (197)", 0 FAIL line(s), unhandled 0, teardown 0. The second run is a real assertion failure, not a teardown flake, in src/core/task/__tests__/Task.spec.ts > Cline > safeEnsureModelFetched > keeps prompt and request tools on one snapshot when the fetch stalls past the bound and resolves late. Runs per target: tip 3 (1 failing), wt-task106-install at 1406 3 (0 failing), at 1412 3 (0 failing). So the flake is inherited from main and is not something my re-root introduced; I am not patching Task.ts in this PR.
Hook fact about my own push, owning it: the push of this head completed in 5 s with 409 B of stderr that contained no build output, because this worktree's .husky/_ was missing the file h that .husky/_/pre-push sources - the shim sourced nothing and exited 0, so git reported a successful push with the hook silently skipped. After copying the 17 husky files from the main checkout (porcelain 0 before and after, .husky/_ is itself excluded by .git/info/exclude:16) the same push as a dry run fired the hook: exit 0 in 11 s, 4,612 B of output 31c237beaeab9924 whose lines are > roo-code@ check-types plus turbo check-types running in 13 packages. The rehearsal pnpm run check-types had already exited 0 in all four PR worktrees (15 s / 9 s / 15 s / 15 s, porcelain 0 after each), but rehearsal is not the push, and for this head the push ran hook-less. Nothing about the delivered content changed.
Local mutation preflight on the unit delta, before the push, in C:/work/Zoo-Code-fork/Zoo-Code/.tmp-cr-audit/s3lane/wt-task100-stryker checked out at this head (e3dd44cb0b65, parent 332d30fbb9d8, its own gate blob 7dfe0006d2d5 30108 B): exit 0 in 2 s, stdout 119 B = Mutation-testing 3 package(s) from merge base 332d30fbb9d8: types (7 lines), extension (468 lines), webview (21 lines), which is a third independent reading of the same table. The mutation half did not run on this host: stderr 606 B is three ::warning title=Mutation test advisory:: lines, spawnSync ... ode_modules.binstryker ENOENT for types and extension and ...webview-ui ode_modules.bin�itest ENOENT, because the gate spawns the extension-less bin path that exists on Linux CI. So I quote no mutant count for this head and I do not treat the leg as advisory evidence about content.
Filter form, because a lane row and a test row are not the same thing: pnpm --dir src run test:services -- -t "<name>" ran the whole lane (1,609 tests, 79.42 s) while pnpm --dir src exec vitest run services/checkpoints/__tests__/ShadowCheckpointService.spec.ts -t "<same name>" printed Test Files 1 passed (1) / Tests 1 passed | 42 skipped (43) in 1.76 s.

@easonLiangWorldedtech Thank you for the correction. My earlier reply cited the old head. GitHub now reports e3dd44cb0b65 as MERGEABLE, with reviewDecision: CHANGES_REQUESTED and mergeStateStatus: BLOCKED. A human review is appropriate.
The saved CodeRabbit gate is also blocking, although it is not a fresh check. Inspection of the current head found:
Persistence:checkpointSave writes an awaiting marker without write metadata at src/core/checkpoints/index.ts Line 277. Recovery clears that marker at src/core/checkpoints/changeJournal.ts Line 321. A crash after commit or failure of both marker writes can therefore lose journal entries. This remains a merge blocker. It needs a recoverable pre-commit intent or rollback, error propagation, and regression coverage.
Lifecycle: A task can be disposed while checkpoint initialization is pending. The save path does not recheck cancellation after initialization. Add cancellation and concurrent-initialization coverage.
Security: The marker entry guard addresses the reported null crash. The requested invalid-entry, invalid-path, and checkpoint-save regression coverage remains unverified.
Settings: The saved check still asks for stored-false and unset-value SettingsView coverage and a committed visual baseline. The repository instructions and retrieved visual-test guidance also describe a pinned GitHub Actions container fallback when Docker is unavailable.
Please rerun the saved checks on the current head. The separate extension-host-visual failure reported in the handoff also needs its job log or a comparison run before attribution. I did not run tests or recheck CI, and I did not change the review state.

### When a UI change needs a snapshot
Visual regression is screen-based, not line-based — the goal is a small set of durable "pixel receipts" for the surfaces users see first, not blanket coverage. Prefer covering:
- Onboarding / first-run surfaces (welcome view, hero, unconfigured state)
- Empty and error states (no history, provider misconfig, degraded modes)
- Theme-critical layouts that rely heavily on `--vscode-*` tokens or CSS masks/gradients
- One representative snapshot per user-facing screen — not per component

### When a UI change needs a snapshot
If your PR changes anything a user would notice at a glance — layout, spacing, theme tokens, brand elements, gradients, mask/blur effects, hover/empty/error states — **add a `*.visual.tsx` snapshot to the same PR**. Do not attach screenshots to the PR description as evidence; commit the baseline instead so future PRs get regression coverage automatically.

Learning: In the checkpoint change stack, pull request #1406 (B2) intentionally journals only `path` and `operation` for `ApplyPatchTool` writes. Stacked pull request #1411 (B3a), commit `5e06d6ce07043011bc4c4ca87eb69c65d89a83b0`, retains approval `diffStats`, `diff`, and `autoApproved` on `ApplyPatchFileChange` and passes them to `checkpointSave` for per-step change cards.
The red on extension-host-visual (check-run 129614390604) is ours, deterministic, and explained - with the fix queued as a numbered unit
Read from the job log through GET /repos/Zoo-Code-Org/Zoo-Code/actions/jobs/129614390604/logs (302 Location, no Authorization header): 312,607 B, sha256-16 f5c4b20b38baec7c, run_attempt 1, so no CI retry hid anything. The step that fails is step 7, Run Extension Host visual tests; the rest of the 13 steps succeed.
One test, three attempts: src/visual/electron.visual.ts:45:6 renders chat-dark in the real VS Code Extension Host, Error: expect(locator).toHaveScreenshot(expected) failed, Locator: locator('.part.sidebar'), Snapshot: electron-chat-dark-sidebar.png, 5061 pixels (ratio 0.03 of all image pixels) are different. Run summary 3 failed / 10 passed (11.0m) where 11 tests run 13 times with retries; welcome-dark and welcome-high-contrast pass in every attempt. All 18 pixel rows in the log carry the same number, and the same 5,061 appears in the sibling legs, so this is not a flake.
Environment excluded: this log and the four others print the same Validated version: 1.100.0 and the same Downloading (142.98 MB) for VS Code on the same job shape.
The repo fixture did not move: apps/vscode-e2e/src/visual/__screenshots__/electron-chat-dark-sidebar.png is blob dfc6fee680c8, 28,998 B at 18861b2e357203e6cb4d93930aa2ed122b1eecea, at this PR parent 332d30fbb9d8852a61b4512a5ce550e10cf84f24, and at the merge result CI actually painted (HEAD is now at f6d0ccc Merge e3dd44cb0b65... into 18861b2e3572...).
What changed instead: this PR turns the task-start baseline on by default. packages/types/src/global-settings.ts adds DEFAULT_PER_WRITE_CHECKPOINTS = true, src/core/webview/ClineProvider.ts resolves it in both state readers, and src/core/task/Task.ts records a pre-task checkpoint at line 3930 with checkpointSave(true, true), where force=true means allowEmpty - so a clean workspace with no writes now produces a checkpoint where main produced none. The checkpoint event broadcasts currentCheckpointUpdated at src/core/checkpoints/index.ts:183-206 with suppressMessage, which hides the checkpoint_saved chat row but not the completion card, and webview-ui/src/components/chat/ChatRow.tsx:1400 renders SeeNewChangesButtons from it. The artifact confirms the pixels: artifact 13733313865 holds electron-chat-dark-sidebar-actual.png 32,757 B (b8b22a6a12682140) against -expected.png 28,998 B (47ad509b278ab68f), and the difference is the See New Changes / Restore Changes row pushing the fixture magenta bar down.
The fix is queued as a numbered unit in the split plan on #1991 (unit task-130: suppress the baseline broadcast only, threaded from Task.ts:3930 into checkpoints/index.ts:183-191, with the two controls that the baseline commit is still produced and that a real user checkpoint still repaints). Its host cannot be this PR: 1406 prices 468 of 500 extension changed executable lines, 32 lines of headroom, and the fix is production code plus its tests. The same cause applies to the three sibling PRs, whose comments already carry their own figures.
Two things this lane considered and declined, stated so a maintainer can overrule them: we did not regenerate the fixture locally, because the committed picture is Linux-rendered by this job and a Windows render is not evidence about it; and we did not treat "every completed task now shows a checkpoint affordance pointing at an empty baseline commit" as settled, because accepting that is a product decision for a maintainer and not one this lane can take by editing a PNG.
Nothing was pushed for this diagnosis and nothing else on this PR was touched: no branch, no thread, no review, no label.
Cross-reference for the planned-and-issued rule: the chain-level split-or-exclusion plan for 1406, 1410, 1411 and 1412 now lives on #1991 ([Tracking] guarded-write chain (epic 1375)), posted by lane s3-1395.
It carries the priced figures with the base named - extension 468 inside the cap of 500 (MAX_CHANGED_LINES at scripts/stryker-diff.mjs:11, instrument blob c332971815aecfaf, 30,108 B / 869 lines) against priced base 18861b2e357203e6cb4d93930aa2ed122b1eecea, and 675, 778 and 1,065 lines over that cap on 1411, 1410 and 1412 - the split-versus-exclusion recommendation with the measured boundaries, and two numbered units that this round discovered: task-130 (suppress the task-start baseline currentCheckpointUpdated broadcast, the cause of the red on extension-host-visual) and task-133 (guard the unguarded error emits in src/services/checkpoints/ShadowCheckpointService.ts:586 and :375).
Host rule recorded on this PR: task-130 cannot be hosted here, because this PR prices 468 of 500 extension lines with 32 lines of headroom and the fix is production code plus its tests.

Visual regression note (2026-08-30): The advisory
extension-host-visualcheck (chat-dark sidebar snapshot) fails on this branch with a deterministic 973-pixel delta localized to the completion-result area. Root cause: the B1 task-start baseline checkpoint (per-write checkpoints default on,allowEmpty) adds a suppressedcheckpoint_savedrow to the message history, whichgetCompletionCheckpoint()picks up, soSeeNewChangesButtonsrender below the completion row; the suite baseline (recorded pre-FWS in #1426) has no such buttons. Every other pixel is identical, and the delta is pixel-identical across all branches containing B1 (1404/1406/1410/1411/1412/1413), while non-B1 branches are green. This is a new-expected-behavior vs stale-baseline mismatch rather than a rendering regression. Flagged for maintainers: either update theelectron-chat-dark-sidebar.pngbaseline on the B1 branch or adjust the scene/component behavior. Advisory check only — it does not block the required gates.Persistence Integrity walkthrough row - fixed
appendChangenow (1) repairs a torn tail - an unterminated final line is terminated before the new entry is appended, so a crash-truncated journal no longer splices the next entry into the fragment and lose both - and (2) fsyncs each append, so a durable checkpoint implies a durable journal entry. Regression tests: append-after-torn-tail loads both the prior valid entry and the new entry; clean-tail appends insert no blank line. Negative control: disabling the tail repair reddens exactly the torn-tail test (1 failed / 23 passed), restored byte-exact.The proposed whole-file atomic-rename/serialization redesign is not adopted: the journal is advisory metadata (rollback reads checkpoint commits;
loadChangestolerates malformed lines by design), per-append fsync removes the durability gap, and whole-file replacement would trade the single-syscall append for an O(n) read-modify-write on every write.Upstream refresh (this push)

Row-14 wave (round 49)
Row-15 wave (round 50)
Row-16 disposition (evidence-grade, no code change)
The Persistence Integrity walkthrough row at this head restates two claims, both already dispositioned or superseded by landed code:
ApplyPatchTool.ts:377add,:445delete,:617move destination,:629update - each with a comment naming the throw it survives), and the outer catch performs an awaited flush of the recorded writes (landed at 43b49b7, hardened at 78275a3: the flush flag is set only when the success path proceeds tocheckpointSave, the settings lookup is cached for the catch, and a rejected catch flush is reported alongside the bookkeeping error). The row's citedApplyPatchTool.ts:244-247is now the awaited success-path flush itself. Regression coverage: "journals the recorded write when a handler throws after its write", "flushes the recorded write from the catch path when the settings read rejects", "reports the catch-path flush failure alongside the bookkeeping error" (negative controls exactly-1-red each).loadChangestolerates malformed lines by design), per-append fsync removes the durability gap, torn-tail repair closes the crash-splice window, and a journal failure deliberately never propagates to the checkpoint error handler (checkpoints stay enabled;index.ts:269-271). The transactionalCheckpointPartialPersistenceErrorhardening of this window is owned by the B3a+ units and landed there; adopting whole-file atomic replacement in B2 was evaluated and rejected (O(n) read-modify-write per append) with rationale above.Row-17 confirmation (REPEAT - registration confirmed, no churn)
The 03:05Z Persistence Integrity row drops the earlier write-recording claim - it now states explicitly that "The ApplyPatch write-recording and awaited catch flush address the earlier bookkeeping-throw path" (the Row-16 disposition accepted). The remaining claim is the commit-then-append window, the registered advisory-journal disposition above (per-append fsync, torn-tail repair, journal failure logged without disabling checkpoints, transactional
CheckpointPartialPersistenceErrorowned by B3a+; the pending-record transaction redesign is the same whole-file-redesign family evaluated and rejected above). Verdict: REPEAT.
