- Around line 6150-6197: Update the “finalizePartialToolAsk still updates the
webview when a later save stage fails” test to isolate its file-backed task
data: remove the persisted ui_messages.json in a finally block, or give the test
a per-test globalStorageUri. Ensure cleanup runs whether assertions pass or

…tests The task uuid is mocked to a fixed value, so the ui_messages.json this save writes outlives the test that created it. The sibling test below removes the whole directory and recreates it, which is the only reason the leak has not surfaced: with merge = true, any later save that reads its merged output would fold in a stale record and fail by run order rather than by behavior. The body now runs in try/finally, removing ui_messages.json and restoring both spies whatever the assertions do. The spies moved out of the try so the finally can see them. Local run: 162 passed in Task.spec.ts (the one remaining failure, blocks a truncated write_to_file call instead of executing it, fails identically at cf5abe6 without this change - local artifact), eslint clean, no suppression change.

Fixed at I kept the shared directory itself in place — the sibling test that removes it recreates it in its own Local run: 162 passed in @coderabbitai full review |

The feat/chat-input-model-selector branch has nothing to do with this series and hit the identical TaskMessagesReadError in the verify phase.
The same code passes elsewhere in this series. Four sibling PRs carry the identical U1 Task.ts content (the saveClineMessages stage split and finalizePartialToolAsk) and passed this step:

Local reproduction status, and why it is not a Vitest run. This check is not a Vitest suite: it is xvfb-run -a pnpm --filter @roo-code/vscode-e2e test:ci:mock followed by TEST_FILE=restart-persistence.test USE_MOCK=true xvfb-run -a pnpm --filter @roo-code/vscode-e2e exec node ./out/runTest.js. It needs a bundled extension (src/dist/extension.js), a built webview (webview-ui/build), a compiled e2e app (apps/vscode-e2e/out) and a downloaded VS Code binary (.vscode-test/); none of those artifacts exist in the Windows working copy here, so a local green would first require the whole build chain rather than a focused test run. The automation token cannot rerun the job either: POST /repos/Zoo-Code-Org/Zoo-Code/actions/runs/37880099804/rerun-failed-jobs returns 403 Must have admin rights to Repository.
Ask. Please rerun the failed job for run 37880099804. No code change is justified by this failure, and no empty commit is being used; the evidence above is the record. If a maintainer would rather see a local run, say so and we will build the E2E artifacts and run the restart scenario directly.
No code change. This empty commit exists only to obtain a new CI run, because the required e2e-mock check is red at c4ca658 and the failed job cannot be re-run with the token available here (POST /repos/Zoo-Code-Org/Zoo-Code/actions/runs/37880099804/rerun-failed-jobs -> 403 Must have admin rights to Repository). Why the red is not caused by this branch: - In job 113657575830, step 14 'Run mocked E2E tests' = success; only step 15 'Run mocked restart-persistence E2E test' failed. The create phase passed ('persists completed task across a fresh extension host', 1 passing); the verify phase threw TaskMessagesReadError: Failed to read task messages for 01a11ec0-9f7e-72db-9721-1c8b2d4d28f4 at /tmp/roo from readTaskMessages <- Task.resumeTaskFromHistory <- TaskScheduler.schedule, then 'Error: Timeout after 30s' (out/suite/utils.js:15). - The previous head on this same branch, cf9206a, passed both steps (run 37516254245, 2026-10-06). The only commit between cf9206a and c4ca658 changes src/core/task/__tests__/Task.spec.ts (+13/-2), a Vitest unit-test file the mocked E2E suite never loads; no production file changed and the branch base is unchanged (7214352). - The identical signature appears on unrelated branches: run 37762259575 (vps2-f2c), run 37706659841 (feat/chat-input-model-selector, same TaskMessagesReadError), run 37626907243 (feat/dte-v2-3-task-runtime-effort). - Four sibling PRs carrying the same U1 Task.ts content passed this step: Zoo-Code-Org#1929 run 37873787271, Zoo-Code-Org#1928 run 37854340884, Zoo-Code-Org#1931 run 37833581055, Zoo-Code-Org#1932 run 37774292614.

…turn-denial-cleanup U1 is on main now, so this branch no longer carries its own copy of the U1 delta: the diff against main is this unit's own change plus the U7 lifecycle work. Conflicts were confined to src/core/task/Task.ts and src/core/task/__tests__/Task.spec.ts (the region U1 rewrote): - Task.ts: kept this unit's evolution of U1's code - the persistTaskMetadata() extraction, the pendingTaskMetadataRepair record and the per-stage result. U1's split semantics (message write reported separately from the metadata stage) are preserved, not re-implemented. - Task.spec.ts: took main's version of the shared later-stage-failure test (try/finally plus the fixed-task-id ui_messages.json cleanup that cf9206a added) and kept this unit's four dispose-time metadata-retry tests on top of it. Local verification after the merge: Task.spec 176 passed; writeToFileTool.spec 67 passed / 5 skipped; DiffViewProvider.spec 84 passed; presentAssistantMessage specs 3 + 20 passed; eslint 0 errors / 0 warnings on every touched file; tsc --noEmit reports 62 errors, all in seven files this unit does not touch (stale built @roo-code/types in this Windows worktree) and identical to the pre-merge baseline.

A tool's streaming preview is added as a partial ask. If the tool then failed (for example "Failed to open diff editor"), the error was reported but the preview stayed partial, and the webview kept rendering its spinner indefinitely. Upstream Zoo-Code-Org#1927 added Task.finalizePartialToolAsk() for this, but only EditFileTool calls it, from its own anticipated failure paths. write_to_file, apply_diff, use_mcp_tool (including native mcp_tool_use calls) and custom tools stream a preview the same way and report failures through presentAssistantMessage's handleError, which never finalized it. Both handleError implementations now call finalizePartialToolAsk() before reporting the error, so every tool gets upstream's handling: it searches backwards for the partial tool ask, clears its progressStatus, marks it answered so Save/Reject is not left armed for a write that failed, and skips the webview update if persisting fails. For EditFileTool the call is a no-op, since the tool has already finalized its preview. presentAssistantMessage-partial-tool-ask.spec.ts drives each of those tools through a streamed preview and a failure, with the real finalizePartialToolAsk; without the handleError call all four cases fail.

U12(1+2) — task save-stage semantics + finalize open partial tool ask
Part of the PR #1066 split (tracking issue #703). Own issue: #1933. Content source of record:
72143527fd33306e5541116093c2cbf803cce9e0..pr-1066-audit).Why this unit exists: saveClineMessages() reports the message-write stage independently of the metadata/task-history stage, and finalizePartialToolAsk() closes an open partial tool ask by type+text. Planned as two units (U1 stage semantics, U2 finalize); merged because the stage-semantics tests call finalizePartialToolAsk, so the test blocks cannot be split without orphaning them (test-block atomicity). Soft budget overshoot: 481 a+d.
