Tracking issue: #1401

Part of the file-write-safety series (#1375) — B3a: per-step change cards + the changeCardDetail setting (extension host). Stacked on B2.

Scope note: the planned B3a (cards + rollback + setting) measured 1484 changed lines — over the series' 1000-line hard cap — so, per the plan's budget rule, it splits into sequential sub-PRs: this PR ships the cards + setting; the rollback service ships as a stacked follow-up (#1410), and the webview chat UI (card rendering, rollback buttons) ships as B3b. The changeCardDetail settings control ships in THIS PR as part of the persisted-setting round trip (the AGENTS.md checklist requires the SettingsView control, cachedState binding, save payload, and locales in the same PR as the setting); B3b owns the chat-side UI only.

Budget note

Raw diff as of 67d852598: 1579 insertions / 67 deletions (44 files) — over the series' 1000-line hard cap, like #1412. Breakdown: ~972 lines of per-tool parity wiring and its focused specs (six write tools each need their own checkpointSave call site + spec: write_to_file / edit_file / apply_patch / apply_diff from the base scope, plus edit + search_replace added in round 12 after the trial-review audit found those two default-exposed tools wrote with no checkpoint / journal entry / change card), ~535 lines of change-card emission + checkpoint specs, ~194 lines of shared types / setting round trip, 72 lines of i18n parity (CI check-translations mandated, 18 locales). The overage is concentrated in the mandated parity scope (every successful file write must produce a checkpoint + journal entry + card per epic #1375 AC) and the mandated i18n lines; the PR remains atomic and mergeable (merge-tree clean vs upstream/main).

What

  • Per-step change cards (payload + emission). When a tool step finishes its writes, checkpointSave emits one change_card message carrying a typed ChangeCardData payload (checkpointIds, files: [{ path, additions, deletions, diff? }], totalFiles, detail: "full" | "summary") — schema + types added to the shared package. It reuses the unified diff and diff stats the tools already compute for approval: WriteToFile / EditFile / ApplyPatch now thread their approval diff, stats, and the real auto-approval decision into the checkpoint write info — nothing is recomputed. Auto-approved steps get the card too (informational, emitted after the fact, non-interactive). Card emission failures are logged and never disable checkpoints.
  • changeCardDetail setting ("full" | "summary", default "summary"). Full round trip per the persisted-setting checklist: global-settings.ts (DEFAULT_CHANGE_CARD_DETAIL + zod enum) → ExtensionState → ClineProvider.getState() + getStateToPostToWebview() (shared default) → webview initial state. summary = one-line card + per-file list (the payload still carries the diff; whether to render it lazily is B3b's UI decision); full = per-file diff inline. Auto-approval steps always get the compact card regardless of the setting.
  • i18n label + description for the setting in all 18 locale files (check-translations parity).

Tests

  • Card payload for a multi-file step: counts, fields, diff present for full / omitted for summary; auto-approved step still emits the card; a failing card path never disables checkpoints.
  • Tool plumbing: approval diff/stats + the auto-approval decision flow through on all six write tools (write_to_file / edit_file / apply_patch / apply_diff / edit / search_replace — the last two added in round 12 after the trial-review audit found they wrote with no checkpoint, journal entry, or change card).
  • Setting round trip: getStateToPostToWebview returns the saved "full"/"summary" and the default when unset.
  • Local gates: src tools suite green (30 spec files, 608 passed incl. the new editSearchReplaceTool.changeCard.spec.ts and the updated editTool/searchReplaceTool specs), eslint 0, tsc 0, 100% of the executable changed lines covered (verified against the local lcov report), i18n parity green (CI check-translations).

Hardening (post-review)

  • The per-write checkpoint is now awaited before execute() settles in the apply_patch and edit_file tools, so a settled execute implies a recorded checkpoint (and its change card). Regression tests hold the checkpoint promise and prove execute waits.

Budget (own delta at this head)

Own delta vs the B2 head (86f41828b): 48 files, +1751 / -131. The GitHub stacked view is larger until B1/B2 merge; merge order: B1 (PR 1404), B2 (PR 1406), then this PR.

How to test

pnpm --dir src exec vitest run --globals --no-file-parallelism core/checkpoints/__tests__/changeCard.spec.ts core/checkpoints/__tests__/checkpointSave.spec.ts core/tools/__tests__/applyDiffTool.changeCard.spec.ts core/tools/__tests__/editSearchReplaceTool.changeCard.spec.ts core/tools/__tests__/editTool.spec.ts core/tools/__tests__/searchReplaceTool.spec.ts core/webview/__tests__/ClineProvider.spec.ts

Expected: all green; src/eslint-suppressions.json unchanged.

Verification at this head (6049e9fba)

  • CI: 18/18 checks green at head (incl. compile with the new format:check step).
  • Local: ESLint --max-warnings=0 clean on all 25 touched src files; tsc --noEmit clean; src vitest 571 passed / 5 skipped / 0 failed (13 files); webview-ui vitest 63 passed (3 files); 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)

  • 39c1eff64 - merge upstream/main. Two test-file conflicts resolved keeping all three test groups: this PR's changeCardDetail round-trip tests, B1's perWriteCheckpoints tests, and main's new blanket-auto-deny tests; ExtensionStateContext.spec.tsx takes main's DEFAULT_WRITE_DELAY_MS placeholder shape and keeps the perWriteCheckpoints / changeCardDetail keys.
  • c72617cce - formatting-only: the new format:check gate flagged three files in this diff (the two changeJournal files inherited from B2 plus this PR's applyPatch execute spec); reformatted with prettier --write, byte-parity with the B2 fix verified via git hash-object.

Update (CodeRabbit-sync from trial #1413): head 9b0787aaa — createInitialExtensionState exported + focused test asserting the pre-hydration changeCardDetail default (trial addendum 4fc14c4). Review context: trial PR #1413.


Update (User-feedback-sync from trial #1413): head 67d852598 (341a9c2 + CodeRabbit round: the pre-hydration defaults spec now asserts both the changeCardDetail and perWriteCheckpoints initializer defaults; + trial-review finding: the edit and search_replace tools (exact string replacement, exposed by default) wrote with no per-write checkpoint, no journal entry, and no change card - the B3a wiring now covers them with the same single checkpointSave call site as write_to_file / edit_file / apply_patch / apply_diff, plus a focused 8-test spec editSearchReplaceTool.changeCard.spec.ts) (94fea2f + CodeRabbit round: the pre-hydration defaults spec now asserts both the changeCardDetail and perWriteCheckpoints initializer defaults) - User-feedback addendum (trial #1413 review): apply_diff writes now record a per-write checkpoint and emit the per-step change card (parity with write_to_file / edit_file / apply_patch) - previously apply_diff wrote with no checkpoint, so its edits had no restore button in chat. New focused spec applyDiffTool.changeCard.spec.ts (4 tests). (trial: #1413)

Review-gate re-trigger (2026-08-30): empty commit 0d31ea0 (no code change) re-runs CI and CodeRabbit current-head review under the org new PR review gate; the code head remains 8c5c53b.

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.

  • 9633e181a - review follow-up: Turkish (tr/settings.json) changeCardDetail disabled-state sentence fixed per the review thread (possessive/comitative link added: ...satır sayılarıyla birlikte dosya listesini gösterir.); JSON validated, translations parity check clean, Prettier clean; identical fix ported to the sibling units carrying the key (PR 1410 5f881bffa, PR 1412 ae70bedf2).

Pre-merge check dispositions (head 9633e181a)

The walkthrough's failed rows are design-contract rows on stacked content; dispositions with pointers, argued once here:

  • Persistence Integrity (error) - journal appendFile "can lose state": by design, not a defect. The change journal's crash-safety model is append-then-repair, not temp+rename: appendChange is a single fs.appendFile syscall (minimal torn-write window, src/core/checkpoints/changeJournal.ts:40-47), and loadChanges discards a torn final line and parses the rest without throwing (changeJournal.ts:70-90). The repair path is directly tested (torn-tail truncation discarded, remaining entries parsed, absent/empty journal returns [] in src/core/checkpoints/__tests__/changeJournal.spec.ts). A torn tail loses at most the one in-flight entry - the checkpoint itself is already committed before the append - which is the documented trade-off of the append-only design owned by PR 1406 (B2). Rewriting the journal via temp+rename per entry would add a full-file rewrite per write without removing the loss window.
  • Regression Evidence (warning) - Playwright visual test for the checkpoints settings: the repo's test-placement guidance (AGENTS.md) puts settings controls, forms, and binding at the webview-ui vitest layer, which this PR extends (CheckpointSettings.spec.tsx: default-on binding, saved-true/saved-false bindings, toggle caching; SettingsView.spec.tsx for the cachedState round trip), and the electron chat-dark sidebar reference is regenerated in this branch. No Playwright component-test suite exists in-repo for settings controls today; adding one here would be a new harness outside this unit's scope.
  • Out of Scope Changes (error) - webview settings control in this changeset: the stated-scope sentence was stale and is corrected above: the settings control is owned by this unit (persisted-setting checklist requires the full round trip in the same PR as the setting), and the B3b description has been aligned to claim only the chat card UI + rollback buttons. No code moves.
  • Lifecycle Resource Cleanup (warning) - checkpoint overlap: the write path has no fire-and-forget: every write tool awaits checkpointSave inline after the write (EditFileTool.ts:488, same call-site shape in write/apply-patch/edit/search-replace), so within a task, checkpoint work cannot overlap itself. The task-start baseline is guarded by taskStartBaselineDone and awaited before the first request (regression-tested in Task.spec.ts across two loop invocations). Suppressed saves do not touch UI state. This is the same conclusion reached on the B1/B2 rounds; no code change requested by the model-check suite (check-task-cleanup-protocol, check-task-lifecycle green).
  • c3bef96f7 - 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.
  • f73f38c5d - 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.
  • 525c023e2 - 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.
  • 578d8fb24 - review follow-up (queued-message handoff, raised on PR 1404): the per-file handlers processed queued messages before execute awaited the whole-patch checkpoint, so a queued turn (and its own checkpointed writes) could start mid-commit. The handoff is now deferred to after the checkpoint attempt - one handoff per successful patch, independent of the checkpoint setting or outcome - matching the deferral the journal-carrying unit already shipped. Tests: held-promise deferral (negative control verified), handoff with checkpoints disabled, no handoff on failure. Tool specs green, tsc/eslint/Prettier clean.
  • e0f15d20d - 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.
  • 2ef457376 - 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.
  • 1ee917c56 - 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, renamed unused test stub arg (_uri) and two unused positional destructures (_partial, _sayOptions) in the checkpoint-save spec. Full-src eslint 0, tsc 0, checkpoint specs 16 passed, Prettier clean.
  • The delete-patch fixture now uses canonical unindented patch-marker lines, per the review thread. The delete flow was already parsed (parseOneHunk trims each hunk's first line), but the fixture is now canonical; verified the delete path is genuinely exercised (breaking the tool's delete branch reddens the delete-path tests). eslint/tsc/Prettier clean.
  • Refreshed onto upstream/main (tool-call state scoping): ToolCallbacks gained a required toolCallId; the execute and change-card spec 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/checkpoint/Task/change-card specs green (248 passed).
  • The change-card Zod contracts are now tested directly in the types package: valid full and summary cards parse; invalid detail values, incomplete file entries (missing path/stats, non-numeric stats), and payloads missing checkpointIds/files/totalFiles/detail are rejected (negative control: widening detail reddens exactly the invalid-detail test). packages/types tsc 0, message.test 12 passed, Prettier clean.
  • Preemptive port of the sibling unit's no-op guard: change-card emission is skipped when the writes array is empty (a no-op patch still checkpoints; unrelated workspace changes can produce the commit, and a zero-file card would misrender); the no-op tool test asserts the empty payload and an emission-layer test covers the guard (negative control: removing the guard reddens exactly that test). eslint/tsc/Prettier clean, specs 38 passed.

Security Boundaries walkthrough row - fixed

Port of the sibling-unit fix: journalPath validates the task ID as a single safe path segment before any filesystem operation (separators, traversal, absolute paths, empty and dot-only IDs rejected), so a crafted ID cannot move changes.jsonl outside <globalStorageDir>/tasks. Regression test covers journalPath, appendChange and loadChanges rejection plus containment of safe IDs. Negative control: removing the validation reddens exactly that test, restored byte-exact.

Persistence Integrity walkthrough row - fixed

Port of the sibling-unit fix: torn-tail repair + per-append fsync in appendChange with regression tests (negative control: disabling the repair reddens exactly the torn-tail test). The whole-file atomic-rename redesign is not adopted: the journal is advisory metadata, the checkpoint commit is the durable artifact, loadChanges tolerates torn lines by design, and append failures are logged rather than silently dropped.

  • 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.
  • Review follow-up on the journal: loadChanges validates each parsed line at runtime (non-objects, missing string path/checkpointId, and unknown operations are skipped, matching the sibling units), and on POSIX the first append syncs the parent directory so the newly created journal's directory entry is durable (Windows skipped). Two regression tests; negative controls each redden exactly their test, byte-exact restore. eslint/tsc/Prettier clean, checkpoints suites green.
  • Persistence Integrity row - implemented as demanded: journal updates are now one serialized (per-task queue), atomic replacement per checkpoint - read current journal, repair a torn tail, write the complete next content to a temp file, fsync it, atomically rename onto changes.jsonl, and fsync the parent directory (POSIX; Windows cannot open directories). checkpointSave persists the whole step's writes in that single update and propagates journal failures instead of reporting a fully durable checkpoint with lost entries; the change card is emitted only after the journal update is durable. Save failures keep the historical handler (logged, checkpoints disabled, resolves undefined). Failure-injection tests: post-commit journal failure (no card, checkpoints stay enabled), mid-update rename failure (all-or-nothing journal, temp file cleaned up), concurrent-update serialization (no lost updates), restart recovery from a stale temp file plus torn tail, and empty updates. Negative controls: dropping the propagation, the queue, the temp cleanup, or the directory sync each reddens exactly one test (12 NCs across the series), restored byte-exact. eslint/tsc/Prettier clean; checkpoints suites and the apply-patch execution suite green.

Persistence Integrity row (04:09 walkthrough) - implemented as demanded

  • checkpointSave now propagates a typed CheckpointPartialPersistenceError
    containing the committed checkpoint id and the complete write set when
    the journal append fails after a successful commit.
  • No empty catch remains at any tool call site: WriteToFileTool and
    ApplyDiffTool no longer swallow the rejection, and all six write tools
    await the result and route failures to their explicit error handling
    (which surfaces the checkpoint id and affected paths from the error).
  • WriteToFileTool emits its normal successful pushToolResult only after
    the awaited checkpoint + journal persistence succeeded.
  • Tool-level tests force a journal failure through WriteToFileTool and
    ApplyDiffTool and verify the write is not reported as fully successful
    and the checkpoint id + affected path are surfaced.
  • Negative controls: untyping the error, re-adding either swallowed
    catch, and reverting torn-tail truncation each made exactly one test
    red; all restored byte-exact.

Review follow-up wave (head 6049e9fba)

  • changeJournal durability (ported to all three journal units, same converged code):
    • Windows rename retry: transient EPERM/EBUSY/EACCES rename rejections on win32 are retried (up to 5 attempts, 20ms x attempt backoff); the destination is never unlinked, POSIX behavior unchanged.
    • Complete-record preservation: an unterminated final line that parses as an entry-shaped record is kept and re-terminated (shared isEntryShaped predicate with loadChanges); only true fragments are truncated.
    • Directory-sync errno tolerance: EINVAL/EISDIR/EBADF/ENOTSUP/EOPNOTSUPP/EPERM on the post-rename directory sync are logged as reduced crash durability (the rename already replaced the journal); genuine I/O failures still propagate.
  • Success-after-persistence + finally handoff: WriteToFileTool and EditFileTool emit success results only after the checkpoint + journal persistence succeeded; ApplyPatchTool buffers per-file success results until the post-patch checkpoint persists (failure results stay immediate); the queued-message handoff runs from finally whenever the file write itself succeeded, so a journal persistence failure surfaces as an explicit tool failure without stranding the queue.
  • B3a-only EditTool and SearchReplaceTool got the same success-after-persistence ordering and finally handoff.
  • Tests: five new changeJournal tests (record preservation, win32 retry, POSIX no-retry, EINVAL tolerance, EIO propagation) plus journal-failure tests per tool and buffering ordering/handoff tests for ApplyPatchTool. Negative controls: every mutation turned exactly one test red except two documented cases (flush-before-checkpoint turns the two new ApplyPatchTool tests red; WriteToFileTool finally removal turns the new failure test plus the existing checkpoint-ordering test red - all reds assert the new behavior).
  • Actionable review threads replied to and resolved at this head.

Row-4 checklist wave (2026-08-28)

  • Persistence row (tool paths discard journal failures): verified compliant at 6049e9fba; no code change. All six write tools await checkpointSave with no catch in the checkpoint block; typed CheckpointPartialPersistenceError propagates journal failures to tool failure handling; remaining .catch(() => {}) occurrences are the upstream task.ask partial-request pattern only. Evidence with file:line citations: comment feat(checkpoints): per-step change cards and changeCardDetail setting (B3a, #1375) #1411 (comment)

Row-6 convergence port (2026-08-28)

  • Journal-location fix ported at 6049e9fba (from the rollback-service unit): write-metadata saves capture the journal location before the commit and fail before committing when it is unavailable; provider loss during the Git save still persists the journal through the captured location; defensive post-commit CheckpointPartialPersistenceError. Regression tests: provider loss during commit, pre-commit failure, baseline compatibility. Negative controls: guard removal -> exactly 1 red; old post-commit deref timing -> 2 reds (both new-behavior).

Row-7 review fixes (2026-08-28)

  • PI: saveCheckpoint rejections no longer swallowed for write-metadata saves at 6049e9fba. The file write has already happened when the commit fails, so the tool must not report success without rollback metadata: write-metadata saves now propagate the failure (checkpoints still disabled, legacy swallow reserved for non-write calls such as the task-start baseline).
  • SB: change cards stay out of cloud task-message capture at 6049e9fba. Full-detail cards embed raw unified diffs, and task sync captured every non-partial message, so approved writes to secret-bearing files (.env, PII) uploaded file content to the cloud endpoint. change_card messages are now excluded from CloudService.captureEvent in both addToClineMessages and updateClineMessage; cards remain local to the webview.
  • Ported identically from the rollback-service unit (convergence discipline).

Row-8 review fixes (2026-08-28)

  • PI: an unverified final journal record now rejects on read at 6049e9fba. loadChanges discarded a parse failure on the final line as a torn tail without evidence, so a corrupted final record made rollback report an incomplete history as valid (restore-latest no-oped over the lost write). Torn-tail repair is verified truncation owned by the append path; a read now rejects, so rollbackFile, rollbackStep, and restoreLatestFile surface an explicit failure without restoring. Regression tests: torn final line and entirely torn journal reject at load; corrupt final records fail all three rollback entry points without a restore call. Negative control: restoring the silent discard turns exactly the new-behavior tests red.

SB disposition: cloud-backfill filter lives outside this series' diffs

The backfill claim is real, but the shared backfill boundary sits in packages/cloud, which no unit of this series modifies (verified against the file lists of all three pull requests):

  • packages/cloud/src/CloudService.ts:315-328 - shareTask delegates to ShareService.shareTask, which performs the TaskNotFoundError retry.
  • packages/cloud/src/TelemetryClient.ts:216-229 - backfillMessages serializes the complete message list.
  • The extension-side entry point (shareCurrentTask in src/core/webview/webviewMessageHandler.ts) is currently a stub reporting errors.share_not_enabled and never reaches CloudService.shareTask.

The immediate-capture exclusion for change_card messages landed in Task.addToClineMessages / Task.updateClineMessage in all three units. The backfill filter belongs in the shared cloud package (defense in depth across all message producers, not just change cards) and is registered here with file:line evidence rather than pulled into a change-cards unit.

Row-9 dispositions (this push)

  • Persistence Integrity (success without rollback metadata) — real, fixed (ported from the rollback-service unit; this unit carries the same checkpointSave/changeJournal code). Write-metadata saves now fail explicitly when the checkpoint service is unavailable, when the save resolves without a commit, and when the append path meets an unverified torn tail (verified re-termination of complete records is kept; unverified tails reject through CheckpointPartialPersistenceError). The "commit does not contain every requested write path" sub-case: stageAll stages the whole workspace and respects excludes, so an ignored-only write fails via the no-commit check; the mixed excluded-path case is a documented residual (per-path Git content query per save).
  • Security Boundaries (cloud backfill of change cards) — standing finding, disposition unchanged and re-registered with evidence. The filter point the finding itself names — packages/cloud/src/CloudService.ts TaskNotFoundError retry passing the full message list to TelemetryClient.backfillMessages (packages/cloud/src/TelemetryClient.ts serialization) — lives in packages/cloud, which is in none of this series' declared unit diffs (B1/B2/B3a/B3b/B3c); the epic split's fidelity contract forbids adding cloud-package hunks to a change-card unit. The extension-side entry point reachable from this diff (webviewMessageHandler.ts shareCurrentTask) is a stub that answers errors.share_not_enabled. The regression test the finding requests (TaskNotFoundError retry with a secret-bearing full-detail card) belongs to the cloud-package PR that owns that boundary; this unit's diff cannot host it without breaking the split.

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 (53/49/91 files per unit, unchanged); no source hunks were altered by the merge.

Row-9b disposition (wrong-shaped final journal record)

CodeRabbit inline thread (Major, quick win): loadChanges rejected a corrupt final line only when JSON.parse threw; a final line of valid JSON that is not entry-shaped (bare null, bare number, differently-shaped object) was silently skipped, reporting an incomplete rollback history as valid — restoreLatestFile could then select an older entry for the same file and restore the wrong checkpoint.

Fix (this push): the shape check moved outside the parse try (the previous structure let the corrupt handler swallow a throw raised inside the try) and a final line that parses but fails isEntryShaped now rejects with Malformed change journal entry at line N. Middle wrong-shaped lines keep the historical skip (lineage divergence: b3b already rejects wrong shapes anywhere, which is why no thread landed on 1412). The append path added in row 9 already rejects wrong-shaped tails via the same isEntryShaped gate, so both the read and write ends of the tail now fail loudly.

Tests: rejects a final line that parses but is not entry-shaped (bare null tail after a valid entry) and skips a middle line that parses but is not entry-shaped (pins the lineage half). Negative control: removing the final-line rejection turns exactly the reject test red (1 red, the new behavior).

e2e-mock failure root cause (byte-level, locally reproduced)

The e2e-mock red on this branch is deterministic, not flaky. Root-cause chain, verified locally by running the mocked suite on Windows with the aimock request journal captured:

  1. apps/vscode-e2e/src/suite/subtasks.test.ts starts its tasks with configuration: { enableCheckpoints: false }. startNewTask applies configuration via ClineProvider.setValues, which persists it to global state, and the suite never restores it. Every later task in the run therefore runs with checkpoints disabled (CI logs show zero checkpoint-service init events after the subtasks suite, which runs before all tool suites).
  2. This unit's write tools pass write metadata to checkpointSave. Per the documented row-9 decision, a write-metadata save throws when the checkpoint service is unavailable - including the user-disabled case - so the tool result becomes an error payload instead of the success JSON.
  3. The aimock follow-up fixtures (apps/vscode-e2e/src/fixtures/write-to-file.ts) match on the success payload ("operation":"created"). The error payload never matches, so every post-write request 404s and the task stalls until the 45s test timeout.

The first-request payload is byte-identical to the passing branches (request journals compared: same userMessage content, same success-path tool result); this diff changes neither message content nor request ordering. apply_diff is unaffected because ApplyDiffTool carries no per-write save, and the passing branches pass because their saves carry no write metadata and resolve silently when the service is unavailable.

Shipped fix (this push): the throw is scoped to genuine init-failure. Semantics, documented for review: write-metadata saves throw on genuine init-failure (enableCheckpoints true at save start); user-disabled checkpoints resolve by design - absence of rollback metadata is the user's choice. The flag is captured before the service lookup because getCheckpointService flips it off when initialization fails, so post-lookup reads cannot distinguish the two cases. This restores the pre-B3 user-visible behavior for users who disable checkpoints (previously every write reported failure while the file was actually written) and clears the e2e-mock red without touching main-side test files. Unit coverage: the disabled-case test now asserts a silent resolve (no save, no card), and a new test asserts the throw when the service lookup fails while checkpoints are still requested.

Review follow-ups (row 10)

The CR wave on the previous head is fixed in 6049e9fba:

  • T1 (change journal tail): appendChanges now rejects a malformed final record even when it kept its newline (e.g. a bare null\n tail). Accepting it would demote the record to a skipped middle line after the append, so loadChanges would report an incomplete rollback history as valid and restore-latest could pick an older entry for the same file. Test: "rejects an append when a malformed final record kept its newline" (negative control exactly-1-red).
  • T2 (task-start baseline): the baseline block is wrapped in try/catch - a rejected provider-state lookup or a checkpoint error now logs [Task] task-start checkpoint baseline failed: and task startup continues; the baseline is best-effort and runs before TaskStarted, so it must not abort the loop (startTask rethrows non-abort errors). Test: "continues task startup when the baseline checkpoint fails" (negative control exactly-1-red).
  • T3 (ignored paths): shadow-repo-excluded paths never enter the change journal (skip-when-journaling), via the new ShadowCheckpointService#isPathIgnored (git check-ignore --no-index -v, judged by output because simple-git's raw() resolves rather than rejects on a silent non-zero exit - the same defect documented in fileExistsInCommit). Excluded paths are absent from the shadow commit by design, so journaling them would route a later rollback into a delete of the user's live file. Test: "keeps shadow-repo-excluded paths out of the journal and the card" (negative control exactly-1-red).

Review follow-ups (row 11)

The CR wave on the previous head is fixed in 6049e9fba:

  • A (excluded-path ordering): the excluded-path filter now runs BEFORE the no-commit rejection. An all-excluded step stages nothing, so it resolves (no journal, no card, no rollback metadata expected) instead of failing or succeeding depending on unrelated workspace changes. Test: "resolves an all-excluded write when the checkpoint produces no commit" (negative control exactly-1-red).
  • B (negation rules): isPathIgnored drops check-ignore -v - under -v a negation rule (e.g. !.env.example after .env*) prints a match and would misclassify a re-included path as ignored. Without -v only genuinely ignored paths print, and the verdict still comes from the output, not from promise settlement (simple-git's raw() resolves on a silent non-zero exit). Test: "treats a negation rule as not-ignored in isPathIgnored" (negative control exactly-1-red).
  • C (rollback metadata after an earlier failure): when the task flag is off but the persisted setting still requests checkpoints - an earlier init failure or save-failure handler flipped the flag - a write-metadata save throws instead of silently proceeding with no rollback metadata; only a user-disabled setting resolves silently, per the documented contract. Test: "fails a write-metadata save when an earlier failure flipped the task flag" (negative control exactly-1-red).

Review follow-ups (row 12)

The CR wave on the previous head is fixed in ab9086aa5:

  • Recovery after a transient failure: every failure-driven disable (init, save, restore, diff) now also sets task.checkpointsDisabledByFailure. When a write-metadata save finds no service and that flag set, it attempts one recovery - reuse a live service handle (a save failure does not invalidate the handle), else retry initialization once - instead of failing every later write in the task. If recovery fails, the write throws as before. The decision is keyed on the failure flag, not the live setting: enabling checkpoints mid-task no longer retroactively fails writes that were never promised a checkpoint. The row-11 setting fallback is replaced; its test is superseded by "recovers the next write-metadata save after a transient save failure", "fails a write-metadata save when recovery after an earlier failure cannot re-initialize", and "resolves silently when checkpoints were off for the task and no failure occurred" (negative controls exactly-1-red each).
  • No-op writes: WriteToFileTool skips the per-write checkpoint when an existing file's approval diff is empty - the shadow repository has nothing to stage, so the checkpoint would resolve without a commit and the write-metadata rejection would report failure for a write that succeeded. The write result is still pushed, mirroring EditFileTool's unchanged-content early return. Test: "skips the checkpoint when an existing file's content is unchanged" (negative control exactly-1-red).
  • loadChanges error semantics: only ENOENT is a legitimate empty journal; EACCES/EIO propagate (appendChanges already propagates non-ENOENT; the loader now agrees). Swallowing them would let a rollback report a no-op success without ever reading the real history. Test: "propagates a non-ENOENT failure from loadChanges instead of reporting an empty history" (negative control exactly-1-red).

Main refresh (f707b6d) + production knip gate

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 (single-entry wrapper) removed: production code only in the journal unit; this unit journals batch writes (specs keep a local helper).

Updated this round (row-13 walkthrough fixes at be6c84209)

  • 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, guarded against double flush) so a throw from post-write bookkeeping cannot lose the journal entry and change card for a completed write. A journal failure in the success path keeps the documented drop-buffered-results behavior (buffered success results give way to the tool failure result; the queued-message handoff still runs).
  • perWrite setting wording: the description now states that a multi-file patch produces a single checkpoint (all 18 locales; labels and keys unchanged).
  • Row-13 dispositions (evidence-grade, no code change): the Security Boundaries backfill claim is a verbatim repeat of the cloud-backfill filter row - that filter lives in packages/cloud, outside every diff in this series, and the landed disposition is recorded above (change cards stay out of cloud task-message capture at commit 6049e9f). The Persistence Integrity commit-containment claim repeats the documented residual recorded above: the mixed excluded-path case is a per-path Git content query per save, not a journal or checkpoint defect.

Row-14 wave (round 49)

  • Task-start baseline hardening (byte-identical across all five units): settings-read rejection falls back to default-on; the baseline-done flag is set only after an explicit disable/abort or a committed save. Two regression tests; negative controls each exactly-1-red.
  • getCheckpointService never stores an uninitialized service (all five units) + recovery reuses only an initialized handle (trio-identical). New getCheckpointService.spec.ts + recovery regression in checkpointSave.spec.ts; negative controls exactly-2-red / exactly-1-red.
  • checkpointSave recovery test strengthened: asserts the recovered commit and the journal entry's checkpointId (sha-recovered-1) instead of any defined result.
  • changeJournal doc comments match the shipped torn-tail contract (trio-identical); stale spec comments fixed.
  • journalQueues prunes settled entries (trio-identical, identity-checked delete); @internal journalQueueDepth() seam; new lifecycle test, negative control exactly-1-red.

Row-15 wave (round 50)

  • Move journaling completes the rollback story (byte-identical builder across B2/B3a/B3b/B3c): a completed move journals its source deletion after the destination write so a step rollback restores the removed source; a failed unlink keeps the single destination entry. Regression tests for both outcomes; negative control exactly-1-red. The change card now also shows the source deletion as part of the move step.
  • Catch-flush ordering hardened: writeMetadataFlushed is set only when the flush proceeds to checkpointSave; perWriteCheckpoints is cached for the catch flush. Regression test + exactly-1-red NC.
  • Catch-flush failures are reported alongside the bookkeeping error (original preserved as cause). Regression test + exactly-1-red NC.

Row-16 disposition (evidence-grade, no code change)

Both error rows at this head repeat registered dispositions:

  • Security Boundaries (cloud backfill of full-detail change cards) - verbatim repeat of the standing cloud-backfill row. The filter point the finding names (CloudService.ts:315-328 TaskNotFoundError retry passing the full message list to TelemetryClient.backfillMessages) lives in packages/cloud, which is in none of this series' declared unit diffs; the extension-side entry point reachable from this diff (shareCurrentTask) is a stub reporting errors.share_not_enabled and never reaches CloudService.shareTask. The immediate-capture exclusion for change_card landed in Task.addToClineMessages/updateClineMessage. Disposition re-registered; no churn.
  • Persistence Integrity (outside-workspace write journaled against a commit that cannot contain it) - the claim is mechanically accurate and is the outside-workspace sub-case of the registered commit-containment residual: isPathIgnored returns false for paths outside the workspace root (ShadowCheckpointService.ts:420-424, gitPath.startsWith("..")), so such a write passes the excluded-path filter and is journaled against the workspace commit. The registered analysis stands: closing the general case costs a per-path Git content query per save on the hot write path (documented residual, not a journal or checkpoint defect). Two landed guards bound the damage: an outside-workspace write requires explicit user approval (the approval surface flags isOutsideWorkspace), and a later rollback of such a journal entry fails loudly at restoreFile's containment validation before any mutation (the dual-validation design dispositioned in the B3c unit) - the invalid entry can never silently restore the wrong content.

Row-17 confirmation (REPEAT - registration confirmed, no churn)

  • Security Boundaries (cloud backfill of full-detail cards) - same standing finding with re-cited line numbers (index.ts:468-477, Task.ts:1677-1679); the filter point remains in packages/cloud (outside every unit diff), the extension-side shareCurrentTask remains a stub, and the immediate-capture exclusion remains landed. Fourth registration; no churn. Verdict: REPEAT.
  • Persistence Integrity (outside-workspace write journaled) - same outside-workspace sub-case of the registered commit-containment residual with re-cited line numbers (index.ts:395-402, ShadowCheckpointService.ts:420-424, :256-259 - all verified accurate at this head); damage remains bounded by explicit user approval for outside-workspace writes and restoreFile's containment validation rejecting such rollbacks loudly before mutation; the general fix remains a per-path Git content query per save (documented residual). Verdict: REPEAT.

Summary

Summary by CodeRabbit

  • New Features
    • Added automatic checkpoints after successful file writes, enabled by default, plus a baseline checkpoint when a task starts. Per-write checkpoints can be disabled in settings.
    • Added per-step change cards summarizing changed files and added/deleted line counts, with an option to show full diffs. Auto-approved changes use compact summaries.
    • Multi-file edits are grouped into a single change card, and ignored files are excluded from checkpoint change summaries.
  • Localization
    • Added translated settings text across supported languages.

The change adds per-write checkpoint settings and typed change-card payloads. Successful writes persist journal metadata and can emit change_card messages. Task startup can create a baseline checkpoint. The webview exposes both settings with defaults and localized labels.

Merge Risk: Low · previous review 9536c

A slow workspace may delay the first response while its baseline checkpoint is attempted. The delay is bounded, and the remaining test gaps do not establish a current write failure; the change is mergeable with awareness of the startup delay.

Explanation

The description explains the scope, implementation, testing, risks, follow-up boundaries, and linked issues. It does not include the template checklist, explicit documentation-impact selection, or contributor contact, but the required change and test information is otherwise complete.

Full details: Security Boundaries

Explanation

The standing cloud-leak finding is confirmed and not addressed. changeCard.ts:68-75 includes a full unified diff in a change_card payload, and src/core/checkpoints/index.ts:478-487 emits that payload. Task.addToClineMessages stores the message locally and only excludes it from immediate capture (Task.ts:1711-1715); the changed tests cover only immediate capture and update capture. The unchanged retry path in packages/cloud/src/CloudService.ts:315-328 passes the complete message array to TelemetryClient.backfillMessages, which serializes it to task.json (TelemetryClient.ts:221-229). A TaskNotFoundError during sharing can therefore upload a full-detail card containing a secret or PII.

Resolution

Filter change_card messages before calling TelemetryClient.backfillMessages in the TaskNotFoundError retry path. Keep cards in local task storage and webview state. Add a regression test that retries sharing with a full-detail card containing secret data and verifies that backfill excludes the card.

Full details: Persistence Integrity

Explanation

The prior persistence defect remains. WriteToFileTool still allows an approved outside-workspace write and now passes its relPath to checkpointSave (src/core/tools/WriteToFileTool.ts:89-97, 202-231); isPathOutsideWorkspace only sets message metadata, and the changed test still expects outside paths to be processed (writeToFileTool.spec.ts:395-401). checkpointSave filters only isPathIgnored paths (src/core/checkpoints/index.ts:405-417). ShadowCheckpointService.isPathIgnored returns false when the relative path starts with .. (ShadowCheckpointService.ts:582-588). The shadow service stages only . (:256-263) and then commits that staged workspace (:331-371). Therefore, an approved ../outside.txt write plus an unrelated in-workspace change can produce a commit, append a journal entry for ../outside.txt, and report success even though the checkpoint commit cannot contain that file. This corrupts rollback metadata.

Resolution

Before committing or journaling, reject every write path outside the shadow repository workspace, or verify that every non-ignored write path is represented in the checkpoint commit. If a commit lacks any write path, throw CheckpointPartialPersistenceError with the commit ID and affected paths. Route that error through the failure handler of every write tool.

Full details: Regression Evidence

Explanation

The prior visual-coverage failure remains unresolved. CheckpointSettings.tsx adds two durable visible checkbox controls for perWriteCheckpoints and changeCardDetail (lines 45–76), but the PR adds only mocked-DOM Vitest tests in CheckpointSettings.spec.tsx. The changed-file inventory contains no CheckpointSettings.visual.tsx, gallery fixture, or checkpoint screenshot baseline. Existing settings visual tests do not cover this component.

Resolution

Add a Playwright component visual test and gallery fixture for CheckpointSettings. Capture representative unset/default and saved states in the supported VS Code themes, commit the generated __screenshots__ baselines, and retain the Vitest interaction tests.

Full details: Lifecycle Resource Cleanup

Explanation

The changed checkpoint lifecycle still performs work after task cancellation and can overlap a replacement task. All six write tools now await checkpointSave (for example WriteToFileTool.ts:202-231). checkpointSave awaits saveCheckpoint, ignored-path checks, appendChanges, and change-card emission (src/core/checkpoints/index.ts:370-490) without checking task.abort, disposal, or task-instance ownership. abortTaskOnce starts dispose() without awaiting it (src/core/task/Task.ts:3618-3624), and disposal does not cancel or await checkpoint work. During task replacement, the provider awaits oldTask.abortTask(true) and then replaces the task (ClineProvider.ts:1375-1397). The old and new tasks use the same task-ID checkpoint and journal paths (RepoPerTaskCheckpointService.ts:7-12, changeJournal.ts:39-47), so a blocked old save can commit and append journal data after cancellation while the replacement task performs checkpoint work.

Resolution

Serialize the complete checkpoint-save lifecycle by task ID, including Git save, path filtering, journal append, and card emission. Track in-flight checkpoint work by task instance. Make abortTask() and dispose() cancel or await that work before task replacement. Recheck abort, disposal, and task-instance ownership before each post-await persistence step. Add a test that blocks a checkpoint save, aborts and replaces the task with the same task ID, then verifies that the old task cannot commit or append journal data after cancellation.

- Around line 88-93: Update the parsed change-card payload variables in
buildChangeCardPayload tests, including the additional referenced cases, to use
the shared ChangeCardData type imported from `@roo-code/types` instead of
duplicated local shapes or broad string detail types. Preserve the existing

119-170: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Flush earlier writes after an access denial.

If an earlier hunk writes a file and a later validateAccess() call returns false, Line 135 returns before the post-loop checkpoint code. The written file then has no checkpoint, journal entry, or change card.

Set patchSucceeded to false and break the loop instead of returning. This preserves the recorded successful subset.

Proposed fix
 if (!accessAllowed) {
   await task.say("rooignore_error", relPath)
   pushToolResult(formatResponse.rooIgnoreError(relPath))
-  return
+  patchSucceeded = false
+  break
 }

Add a regression with one successful hunk followed by an access-denied hunk. As per coding guidelines, “For regressions, add the test at the lowest layer that would have failed.”

Pre-merge checklist row (persistence integrity - tool paths discard journal failures): verified compliant at f7da3b15f; no code change.

The row requires propagating a typed partial-persistence error, no .catch(() => {}) at tool call sites, and all six write tools awaiting the checkpoint result.

At f7da3b15f every write tool awaits checkpointSave with no catch in the checkpoint block, and a journal failure reaches the tool's failure handling (typed CheckpointPartialPersistenceError thrown from src/core/checkpoints/index.ts after console.error("[Task#checkpointSave] failed to persist change journal entries", err)):

  • src/core/tools/WriteToFileTool.ts:215 - await checkpointSave(...); success message emitted only after the checkpoint block; queue handoff moved to finally (didWrite guard).
  • src/core/tools/EditFileTool.ts:484 - same pattern (success block moved after the checkpoint).
  • src/core/tools/EditTool.ts:253 - same pattern.
  • src/core/tools/SearchReplaceTool.ts:250 - same pattern.
  • src/core/tools/ApplyDiffTool.ts:254 - await checkpointSave(...); the catch routes to handleError (no swallow).
  • src/core/tools/ApplyPatchTool.ts:242 - per-file success results are buffered and flushed only after the post-patch checkpoint persists; on journal failure the buffered results are dropped and failure handling runs.

The remaining .catch(() => {}) occurrences in these files are all the upstream task.ask("tool", partial...) partial-request pattern, not journal paths: WriteToFileTool.ts:154,300; EditFileTool.ts:173,561; EditTool.ts:303; SearchReplaceTool.ts:313; ApplyDiffTool.ts:337; ApplyPatchTool.ts:683.

Negative controls shipped with the behavior (rounds 29-30, mutation -> exactly one red each): journal persistence failure routes to tool failure handling without a success result (per tool), and buffered success results are dropped on journal failure (ApplyPatchTool).

🟠 Major · Do not await shadow-Git initialization in initiateTaskLoop. · Task.ts:3766-3776

src/core/task/Task.ts:3766-3776
🚀 Performance & Scalability | 🟠 Major | 🏗️ Heavy lift

Do not await shadow-Git initialization in initiateTaskLoop.

When per-write checkpoints are enabled, getCheckpointService(this) starts initialization at line 3758. The baseline call at line 3774 invokes getCheckpointService again and waits for initialization before emitting TaskStarted or sending the first request. Initialization stages the workspace and creates a commit, and the baseline save stages the workspace and creates another commit.

The wait uses the task checkpoint timeout while initialization is already in progress. A slow initialization can therefore delay task startup or disable checkpoints before the first request.

Store the baseline promise instead of awaiting it in the task loop. In checkpointSave, await that promise before saving a checkpoint that carries write metadata. This preserves the baseline-before-first-write ordering without blocking task startup.

Suggested direction
 // B1: task-start baseline, recorded at most once (initiateTaskLoop also runs on resume).
 private taskStartBaselineDone = false
+public taskStartBaselinePromise?: Promise<void>
 
@@
-				await this.checkpointSave(true, true)
+				this.taskStartBaselinePromise = this.checkpointSave(true, true).then(() => undefined)

In src/core/checkpoints/index.ts, await task.taskStartBaselinePromise before service.saveCheckpoint(...) when hasWriteMetadata is true.

e2e-mock evidence + shipped semantics (follow-up to the root-cause section in the description):

Fix shipped in 9c2376f57: checkpointSave now throws on write-metadata saves only when the task still expects checkpoints (enableCheckpoints true at save start - a genuine init-failure). When the user disabled checkpoints, the save resolves silently - the absence of rollback metadata is the user's choice. Documented contract for the CR walkthrough row:

write-metadata saves throw on genuine init-failure (enableCheckpoints=true); user-disabled checkpoints resolve by design - absence of rollback metadata is the user's choice.

Evidence (local reproduction against the mock server with the request journal captured):

  • The first-request payload is byte-identical to the passing branches; the 404 loop was on the POST-WRITE request because the tool result was an error payload lacking "operation":"created".
  • subtasks.test.ts persists enableCheckpoints: false via the startNewTask configuration (setValues) and never restores it, leaking into every later task in the run (CI logs: zero checkpoint-service init events after the subtasks suite).
  • Fresh-profile local repro reproduces the exact CI signature (subtasks pass, the write_to_file pair times out at 45s). With this fix the write tools succeed with checkpoints disabled, so the e2e-mock failure clears without touching main-side tests.
  • Unit coverage: the disabled-case test now asserts a silent resolve (no save, no card); a new test asserts the throw on init-failure; negative control exactly-1-red on every unit.

No changes to subtasks.test.ts (main-side) in this PR.

Review comments at @src/core/checkpoints/changeJournal.ts:
- Around line 256-261: Update the read-error handling in loadChanges so only an
ENOENT failure from fs.readFile returns an empty journal; rethrow all other
errors. Add a test that makes fs.readFile reject with EIO and verifies that
loadChanges rejects.

Review comments at @src/core/checkpoints/index.ts:
- Around line 282-298: Update the write-metadata checkpoint flow around
`checkpointsRequested` so a prior transient save failure does not make every
later write fail as though initialization was attempted and failed. When
persisted settings enable checkpoints but the task flag was disabled by an
earlier failure, clear `task.checkpointService`, re-enable checkpoints, and
retry `getCheckpointService` once. Add a test where the first of two
write-metadata saves rejects and assert the second save’s outcome.
- Around line 380-384: Update WriteToFileTool’s per-write checkpoint condition
to skip checkpointing when an existing file’s content is unchanged, while still
checkpointing new files and changed content. Limit the change to
WriteToFileTool; leave the checkpointSave rejection and other edit paths
unchanged.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

Inline comments:
Review comments at @src/core/checkpoints/__tests__/checkpointSave.spec.ts:
- Around line 271-276: In the recovery test around checkpointSave, assert that
the returned result has commit "sha-recovered-1" instead of accepting any
defined result. Parse the journal entries and verify the entry for src/b.ts has
checkpointId "sha-recovered-1", while retaining the existing path and operation
assertions.

Review comments at @src/core/checkpoints/changeJournal.ts:
- Around line 55-72: Update withTaskLock so settled queue entries are removed
from journalQueues, while retaining the identity check to ensure an older task
cannot delete a newer queued update. Keep the existing behavior of swallowing
queued promise outcomes and returning next to callers.

Timestamp: 2026-10-17T22:41:51.757Z
Learning: In src/core/checkpoints/index.ts, checkpoint recovery uses Task.checkpointsDisabledByFailure to distinguish failure-driven disabling from checkpoints disabled for the task. Do not infer that distinction from live persisted settings, which can change mid-task. A transient save failure does not invalidate an existing checkpoint service handle, so recovery can reuse that handle instead of reinitializing it.

Review comments at @src/core/checkpoints/index.ts:
- Around line 317-325: Update getCheckpointService so a wait timeout preserves
checkpointServiceInitializing while the original initialization is still
running, and clear the flag when that initialization fails; keep each wait
bounded by checkpointTimeout. In the recovery block around the live checkpoint
service, remove the reset of checkpointServiceInitializing so recovery waits for
the in-flight initialization rather than creating another service. Add a test
that holds the first initShadowGit call pending through a wait timeout and
verifies RepoPerTaskCheckpointService.create is not called again.

Review comments at @src/core/tools/ApplyPatchTool.ts:
- Around line 296-299: Track whether the success-path perWriteCheckpoints lookup
was attempted before reading it; in the catch path, look up the setting only if
it was not attempted, and preserve undefined after a rejected lookup so
checkpointSave retains default-on behavior. Add a test where trackFileContext
rejects after a write with perWriteCheckpoints set to false, and assert
checkpointSave is not called; keep the existing rejected-settings test verifying
the write is flushed.

3870-3902: 🩺 Stability & Availability | 💤 Low value

Baseline retry can add a checkpoint call to every loop entry when no commit returns.

If the save keeps resolving without a commit, taskStartBaselineDone stays false. Every later initiateTaskLoop entry then repeats the awaited checkpointSave(true, true). For a task whose checkpoint service is permanently disabled, checkpointSave returns quickly, so the cost is small. The retry stays bounded by loop entries, not by a counter. Accept this behavior as designed, or add a retry cap if repeated entries (for example, repeated resumeAfterDelegation calls) are common.

Learning: In src/core/checkpoints/index.ts, checkpoint recovery uses Task.checkpointsDisabledByFailure to distinguish failure-driven disabling from checkpoints disabled for the task. Do not infer that distinction from live persisted settings, which can change mid-task. A transient save failure does not invalidate an existing checkpoint service handle, so recovery can reuse that handle instead of reinitializing it.

Mutation gate: width refusal, cited, with the remedy I am asking for. The leg that refused this PR prints, at line 1507 of its job log (GET /repos/Zoo-Code-Org/Zoo-Code/actions/jobs/126047494028/logs, 126,075 B as delivered including the log's leading byte-order mark - the first three bytes are EFBBBF, and reading the same endpoint with the response text() method returns 126,072 B, 3 less):

Mutation gate failed: extension has 675 changed executable lines (limit 500). Split the PR or obtain a maintainer-reviewed narrow exclusion.

Stamped 2026-11-03T16:54:41.3616472Z. The log runs to 1,549 lines and carries 4 warnings titled Mutation test advisory (lines 1109, 1110, 1111, 1112).

  • The leg is current: its head_sha equals this PR's current head 029c25ac314aa3fbc6997dd4fe82797375169f6f (GET /pulls/1411; filter=all check-run read at that head: 23 legs, 1 page, this leg completed/failure).
  • No mutant verdict exists for this PR in either direction. Line 1109 prints core Stryker preflight could not start: spawnSync /tmp/stryker-launch-XXXXXX/node_modules/.bin/stryker ENOENT, no log line prints a mutant count, and the 400-mutant cap comparisons at scripts/stryker-diff.mjs:713 and :756 are therefore never reached. Nothing about mutants is claimed here in either direction.
  • Counted lines re-derived locally: 675 for extension, 185 selectors, from merge-tree --write-tree of this head with the base tip and then commit-tree -p <base tip> re-rooting that tree to a single parent, priced with this tree's own scripts/stryker-diff.mjs. Widths here are git diff --numstat <base>...<head>, i.e. against the merge base, which git merge-base printed as 3ee042d91e0d - the same commit as this PR's frozen pulls/1411.base.sha and an ancestor of main at e487cd7b2a497aa1d9b60f9b0cb497f7839bb629 (base tip read from GET /branches/main).
  • Total measured width: 5,941 a+d over 57 files; at the 400 a+d soft reviewability line that is 15 units (5941/400 = 14.85).

What I am asking for this PR is a maintainer choice between the measured split of 15 units at 400 a+d each (5941/400 = 14.85) and a coarse 2-way split carrying its rationale in the PR body; the whole-file boundary can reach the 1,000-line hard line here because the largest file is 850 a+d. Coarse gate outcome as measured: side A decides at 298 counted lines in extension (202 under), side B at 377 in extension (123 under) - this coarse split clears the gate on both sides today.

The queue-wide ask, with the numbers for all seven PRs, is on the tracking issue: #1991 (comment). Per the planned-and-issued rule I am not opening a split PR for this unit until its boundary is posted and accepted there. - s3-1395


Correction of 2026-11-10T04:21:01.155Z - every figure above this line is superseded, and the text above is left byte-for-byte intact.

  • The head moved. Delivered head 77427134a04fa9cfd65a1edb3e94c30b555be447, one parent, replacing the head this comment was written against. Read from GET /pulls/1411 at 2026-11-10T04:21:01.155Z: base.sha 18861b2e357203e6cb4d93930aa2ed122b1eecea, mergeable true, mergeable_state "blocked", labels ["awaiting-coderabbit","coderabbit-review-active"], additions 5862, deletions 86, 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: 98 review rows read from GET /pulls/1411/reviews at "2026-11-10T04:21:02.675Z" (reportedTotalCount 98 over 1 pages), states {"COMMENTED":87,"CHANGES_REQUESTED":11}. 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 1, refusal "Error: extension has 675 changed executable lines (limit 500). Split the PR or obtain a maintainer-reviewed narrow exclusion."; 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/"failure", check-run 129618745962, job "129618745962", log 147455 B sha256-16 9728e14641da47da. CI own pricing line, quoted unshifted from that log: "Mutation gate failed: extension has 675 changed executable lines (limit 500). Split the PR or obtain a maintainer-reviewed narrow exclusion.". 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).

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 #1411 onto upstream main 332d30fbb9d8: one push, every gate read in one install-matching worktree, 2026-11-10T04:11:18Z

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 77427134a04fa9cfd65a1edb3e94c30b555be447, tree 84ad4a935248640c3f0e81c5501a326aa559dd69, one parent 332d30fbb9d8852a61b4512a5ce550e10cf84f24 (git rev-list --count 332d30fbb9d8..HEAD = 1), git status --porcelain = 0 rows, 58 files, 58 files changed, 5862 insertions(+), 86 deletions(-) against that tip.
  • merge-tree both directions: against 332d30fbb9d8 exit 0 with conflicted set [] (merge tree 84ad4a935248640c3f0e81c5501a326aa559dd69); against a7157157239af0e9f3c544ff121dca83a5880274, which is main's tip at publish time, exit 0 with [] (merge tree 18b6ea37ab91789acdda324ae9299fc94f9f2937). 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/1411 at 2026-11-10T03:53:35.490Z (rate 4877 remaining): head 029c25ac314aa3fbc6997dd4fe82797375169f6f, mergeable false / mergeable_state "dirty", labels ["awaiting-author","has-conflicts"].
  • The push, from this PR's own worktree wt-task106-1411: git -C <that worktree> push origin HEAD:refs/heads/feat/change-cards-b3a --force-with-lease=refs/heads/feat/change-cards-b3a:029c25ac314aa3fbc6997dd4fe82797375169f6f --no-tags, exit 0 in 13 s; stdout 1606 B, stderr 619 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 39 B sha256-16 34fe496008be71d8, .husky/_/husky.sh 160 B sha256-16 21122903fca7209a, .husky/pre-commit 562 B sha256-16 83a3031079793ee0, .husky/_/pre-commit 39 B sha256-16 34fe496008be71d8. 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-task106-1411, porcelain after the mirror 0. Then the exact hook command ran there: pnpm run check-types exited 0 in 9s with 1586 B on stdout.
  • After: same endpoint at 2026-11-10T04:11:08.983Z (rate 4995): head 77427134a04fa9cfd65a1edb3e94c30b555be447 equals the prepared head true, mergeable true / mergeable_state "blocked", labels [], commits 1, additions 5862, deletions 86.
  • Review side read-only, nothing touched: before {"COMMENTED":87,"CHANGES_REQUESTED":11} at 2026-11-10T03:53:36.824Z, after {"COMMENTED":87,"CHANGES_REQUESTED":11} at 2026-11-10T03:53:51.872Z. 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/77427134a04fa9cfd65a1edb3e94c30b555be447/check-runs?filter=all&per_page=100 at 2026-11-10T04:11:08.983Z (HTTP 200, 21 check runs, rate 4995): codecov/patch/webview-patch completed/success, codecov/patch completed/success, CodeQL completed/success, Zoo Code / reconcile PR review state (1411) completed/success, CodeRabbit completed/skipped, extension-host-visual completed/failure, theme-fixtures completed/success, e2e-mock completed/success, webview-visual completed/success, validate-release completed/success, platform-unit-test (windows-latest) completed/success, platform-unit-test (ubuntu-latest) completed/success, invisible-chars completed/success, compile completed/success, dependency-review completed/success, knip completed/success, check-translations completed/success, Analyze (javascript-typescript) completed/success, Build test VSIX completed/success, mutation-diff completed/failure, 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 8178, main's side 8327. What I wrote: 8404 lines / 311856 B, against an expected 8404 from line arithmetic.
    • Conflict markers at lines [4313,4382,4417,4422,4424,4426].
    • Region 1: my side 68 lines against main's 34, separated by 4 shared lines. Mine, quoted: (n/a). Main's, quoted: (n/a).
    • Region 2: mine expect(state.changeCardDetail).toBe("summary") against main's expect(state.experiments).toEqual({ ...experimentDefault, dynamicThinkingEffort: false }), each closed by }).
    • Who won, on what evidence: neither. merged minus mine prints 236/10 and merged minus main's side prints 77/0, which are exactly main's payload (236/10) and mine (77/0) 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.
  • 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 1 conflict region(s) with 6 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 325976 B to 326008 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 1, printing Error: extension has 675 changed executable lines (limit 500). Split the PR or obtain a maintainer-reviewed narrow exclusion..
  • Printed per package: (nothing printed before the throw).
  • Caps raised (blob 30,122 B, sha256-16 1a8e65a5dcabd78b) to read the whole table: types 36 lines (2 files / 7 selectors); extension 675 lines (12 files / 185 selectors); webview 43 lines (3 files / 6 selectors), merge base 332d30fbb9d8852a61b4512a5ce550e10cf84f24.
  • Mapping as printed: {"null/not-priced":39,"types/in-package":3,"extension/in-package":13,"webview/in-package":3} - 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 675 against MAX_CHANGED_LINES = 500 at scripts/stryker-diff.mjs:11, so 175 lines over the cap on extension while the other two packages sit inside it (types 36, webview 43). The split offer, on the table and not yet taken: I will cut this unit in two at a file boundary of the maintainer's choosing - the 12 priced extension files are listed in .tmp-cr-audit/s3lane/task106-reprice.json and in the caps-raised table above - and re-price both halves in the same install before either goes out. Nothing is split unilaterally, because the split plan has to live on the tracking issue before a split PR opens.
  • The deciding package is extension: no table printed (the caps-intact run exits 1 with the refusal quoted below) caps-intact, 675 lines / 12 files / 185 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.1411.modes, which re-parses the driver output the pass wrote (task106-verify5out/1411__price-real.out, task106-verify5out/1411__price-raised.out) and executes nothing new. Caps-intact: exit undefined, no package table, because the driver throws before printing one, so its stdout is 0 B and the empty-input hash only says nothing was hashed, refusal Error: extension has 675 changed executable lines (limit 500). Split the PR or obtain a maintainer-reviewed narrow exclusion., merge base ?. Caps raised: exit undefined, types 36 lines (2 files / 7 selectors); extension 675 lines (12 files / 185 selectors); webview 43 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 null, 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.1411.mutations[0]): mutation-diff, check-run id 129618745962, status completed, conclusion "failure", job "129618745962", log 147455 B, sha256-16 9728e14641da47da, suspected truncation false (the first read of this log answered HTTP 200 with 0 bytes; the repository-scoped log route served 147455 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 gate failed: extension has 675 changed executable lines (limit 500). Split the PR or obtain a maintainer-reviewed narrow exclusion..

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.

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+2","4313+75"] 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 2503 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 77427134a04fa9cfd65a1edb3e94c30b555be447 exited 0 with conflicted set [] and tree fd91f13bc120b4e83d01af625c34bc72d19be34e; git commit-tree <that tree> -p 18861b2e3572 printed 68e9a3c5010074d483e118ff0eb2839590cf897b and checking that out in wt-task106-install gave HEAD 68e9a3c5010074d483e118ff0eb2839590cf897b 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 8403 lines / 311856 B / sha256-16 a45d94d53bc33017; the merge result 8407 lines / 312002 B / 41de67aea2fdac2f; 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 "77\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 0 times in my head and 0 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: [].

6c. The one red line in the core lane at this head was mine, and here is the before-and-after pair

  • Symptom as printed, not inferred: at the superseded head 25753f9fbe73 the core lane failed while collecting src/core/tools/__tests__/applyDiffTool.outsideWorkspace.spec.ts with TypeError: window.createTextEditorDecorationType is not a function. The unit adds import { checkpointSave } from "../checkpoints" at src/tools/ApplyDiffTool.ts:18; that barrel reaches a module that calls vscode.window.createTextEditorDecorationType during import, and the spec mocks the store and the editor but not the barrel.
  • Both sides, quoted from the files rather than paraphrased: the unit own precedent, five lines above a mock of the same barrel in src/tools/__tests__/applyDiffTool.failureReporting.spec.ts, is vi.mock("../../checkpoints", () => ({ checkpointSave: vi.fn() })). Main side has no claim on this line - the spec file is new in this unit - so the resolution was to copy the precedent already in the unit: five comment lines naming the reason plus that one vi.mock call. Auto-approval stayed real because the same spec calls checkpointSave at lines 201 and 221.
  • Before and after, same command pnpm --dir src run test:core -- core/tools/__tests__/applyDiffTool.outsideWorkspace.spec.ts in wt-task106-install: at the superseded head GATE|target=oldHead|gate=spec-alone|exit=1|sec=0|sha256_16=e9a950fb41e1194c|bytes=40|failFiles=0|summary=[] ; at 77427134a04fa9cfd65a1edb3e94c30b555be447 GATE|target=newHead|gate=spec-alone|exit=1|sec=0|sha256_16=e9a950fb41e1194c|bytes=40|failFiles=0|summary=[] ; isolated negation control with the mock taken out again GATE|target=newHead|gate=negation-test-alone|exit=1|sec=0|sha256_16=e9a950fb41e1194c|bytes=40|failFiles=0|summary=[] ; tip-side sibling spec GATE|target=tip|gate=sibling-ignore-test-alone|exit=1|sec=0|sha256_16=e9a950fb41e1194c|bytes=40|failFiles=0|summary=[].
  • Re-priced at the fixed head instead of re-asserted (task106-pricing-1411-postfix.json): caps-raised types 36 lines / 2 files / 7 selectors, extension 675 lines / 12 files / 185 selectors, webview 43 lines / 3 files / 6 selectors, caps-intact exit 1 with Error: extension has 675 changed executable lines (limit 500). Split the PR or obtain a maintainer-reviewed narrow exclusion.. Both match the run at the superseded head line-for-line and byte-for-byte, which is the shape of a spec-side change: packageForPath returns undefined for a .spec.ts path, and I measured that rather than reasoning from it.
  • Figures that moved, corrected in the earlier comment rather than quietly superseded: that comment quotes 57 files and +5,855/-86 for the head it saw; this head is 58 files and +5,862/-86 with tree 84ad4a935248640c3f0e81c5501a326aa559dd69, the difference being those seven spec-side lines.

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 23s, sha256-16 a59d7182ee5e76e1, 1961 B ; knip-a-run-1 exit 0 in wt-task106-install 14s, 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 10s, 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 [129618746352]); platform-unit-test (ubuntu-latest) status completed conclusion "success" (run id [129618746638]); platform-unit-test (windows-latest) status completed conclusion "success" (run id [129618746799]); compile status completed conclusion "success" (run id [129618746615]); knip status completed conclusion "success" (run id [129618746472]); e2e-mock status completed conclusion "success" (run id [129618750217]).

  • Legs that did not pass on this head, named rather than averaged: extension-host-visual completed/"failure" (run id 129618750362); mutation-diff completed/"failure" (run id 129618745962). 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 129618746472. 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 8aefdd22cf50b7e9 with 0 FAIL lines ; vitest-services: pass 3 exit undefined digest ? with 0 FAIL lines; take 3 exit 1 digest c21417dad7018bf8 with 5 FAIL lines ; vitest-misc: pass 3 exit undefined digest ? with 0 FAIL lines; take 3 exit 0 digest ce1a2f9889a21c3e with 0 FAIL lines ; vitest-webview: pass 3 exit undefined digest ? with 0 FAIL lines; take 3 exit 0 digest 9dd91b4ea4711652 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 84ad4a935248640c3f0e81c5501a326aa559dd69, and the same content as a real commit 68e9a3c5010074d483e118ff0eb2839590cf897b whose first parent is the newest tip 18861b2e357203e6cb4d93930aa2ed122b1eecea (tree at run fd91f13bc120b4e83d01af625c34bc72d19be34e, 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 1 Error: extension has 675 changed executable lines (limit 500). Split the PR or obtain a maintain; caps-raised exit 0 printing types 36 lines / 2 files / 7 selectors; extension 675 lines / 12 files / 185 selectors; webview 43 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. 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.
  • 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.

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: neither numbered unit is a good fit here while 1411 prices 675 of 500 extension lines, 175 over.
