FINAL (U7) — clean partial state on missing-param and rooignore denial + integrate the upstream PR 1066 split series

Tracking issue: the split plan (the split plan is recorded there before any split PR opened).

Content source of record: tag pr1066-source = 46d1d218701f0ce2d675b1b315489bacb6b0f77d on easonLiangWorldedtech/Zoo-Code — the verified head of PR 1066. This PR is the sole merge target of the series; the six chain PRs are review units and are merged strictly in order.

Chain (merge order)

#	Unit	PR	Branch	a+d	Files
1	U12 task save-stage semantics + finalize open partial tool ask	1927	`p1066/u1-task-save-stages-and-partial-ask`	481	3
2	U4 per-task partial stream state + cleanup primitives	fork #65	`p1066/u4-per-task-stream-state`	428	5
3	U5 streaming failure capture + single error reporting	fork #66	`p1066/u5-streaming-failure-capture`	283	2
4	U3 onParameterParseFailure teardown boundary	fork #67	`p1066/u3-parse-failure-boundary`	253	3
5	U6 execute() error-path cleanup invariant	fork #68	`p1066/u6-execute-error-path-cleanup`	439	2
6	U7 early-return / rooignore-denial cleanup	1928 (this PR — U7 is the last unit, so its unit PR and the integration PR are the same PR)	`p1066/u7-early-return-denial-cleanup`	241	2

Total: 2025 a+d / 8 files — identical to PR 1066 (2025 a+d), reconstructed unit by unit.

Fidelity

The final head is byte-identical to the content source of record for all 8 files (zdt split verify PASS on every unit; the only intentional additions are the two sanctioned allowNew test files listed in the unit PRs).

Verification (final state)

Tests (narrowest relevant suites): 264 passed / 5 skipped, exit 0 — measured at the tagged content; the current head's numbers are in Review-driven additions after the tag.
Changed-line coverage at the final state: 109 covered / 0 uncovered — PASS (the two lines reported as uncovered in a combined run are covered when removeClineFromStack-delegation.spec.ts runs on its own; the combined run resolves that module through a mock).
ESLint (--prune-suppressions --max-warnings=0): clean on all 8 touched files; suppression counts unchanged.
No .changeset file, no CHANGELOG edit.
Changed executable lines: 211 / 500 cap; valid mutants: 116 / 400 cap — both under the gate, so no directive was added.

Why the split

PR 1066 was not split because a gate failed (CI is green, both mutation caps are respected). It was split for reviewability: 2025 a+d across 8 files and 40 commits in one PR, with 28 CodeRabbit threads spanning two provider groups (Task persistence + WriteToFileTool streaming). Each unit is one provider group + one gate scope.

Deviations recorded in the plan

Planned U1 + U2 merged into U12: the stage-semantics tests call finalizePartialToolAsk(), so the test blocks cannot be split without orphaning them (test-block atomicity).
reports a filesystem error only once across the streaming and execute phases re-attributed from U5 to U6 — it depends on the execute() error-path restructure.
U4 carries a focused cleanup spec (sanctioned new content): the primitives' catch arms are only reachable by calling them directly at this layer.
Accepted mechanism divergence: per-task keying diverges from sibling streaming tools that still use BaseTool's singleton lastSeenPartialPath/resetPartialState; lifting it to BaseTool is a follow-up PR.

Recreate policy

If the bot stalls on a pre-merge check and the existing head cannot obtain bot review/approval (empty-commit re-trigger attempted and failed), the unit is recreated from the tagged content source of record — never from a per-PR head. At most 1 PR per issue.

U7 unit content (this PR's own delta)

Early-return and rooignore-denial branches clear the per-task partial state and finalize the open ask. Unit delta as tagged: 241 a+d / 2 files, base 9b93a6f88 (U6 head), head 646c78739.

Review-driven additions after the tag

The head is now aa959bf12. On top of the tagged unit content the branch carries these fixes, each pinned by negative controls:

Commit	What it fixes	Delta
`ddd35071c`	`handlePartial()` re-checked nothing after `provider.getState()` / `fileExistsAtPath()` / `task.ask()`, so a cancelled task re-asked and re-opened a diff view. Added `isPartialStreamStillLive()` (identity, not presence) after each await.	—
`711aab155`	An abandoned partial stream was released through `revertChanges()`, whose new-file branch SAVES the dirty buffer before unlinking, so unapproved partial model output could reach disk. Added `DiffViewProvider.discardUnapprovedStream()`, which blanks the buffer with an empty replacement before the only save.	—
`876a93b22`	`discardUnapprovedStream()` was not failure-safe and left `createdDirs` behind; `handlePartial()` had no check after `await diffViewProvider.open()`.	4 files, +173 / −37
`d585c6383`	Only `teardownAbandonedStream()` used the safe path: `cleanupFailedPartialStream()`, `onParameterParseFailure()` and the pre-approval branch of the `execute()` catch still rolled back through `revertChanges()` — for a `.rooignore`-denied path that writes back content the policy forbids. `revertDiffChangesBeforeReset()` now delegates to `releaseAbandonedDiffView()` (modify -> `revertChanges()`, new file -> discard).	3 files, +87 / −52
`14fd87fda`	The `d585c6383` review: artifact cleanup no longer depends on `activeDiffEditor` (a create whose `openDiffEditor()` rejected leaked the placeholder and its directories); the `validateToolUse` catch and the tool-repetition break now tear the abandoned stream down; the metadata / task-history stage became `persistTaskMetadata()` with its own result plus one awaited retry in `disposeOnce()`; and the cleanup-failure paths gained tests.	6 files, +279 / −33
`475d9e66b`	The dispose-time retry awaited `taskApiConfigReady`, so a never-settling api-config initialization would have hung teardown.	2 files, +31 / −1
`3a0065091`	The `475d9e66b` review: `discardUnapprovedStream()` could delete a file the user had approved (`relPath` survives `reset()`, and `saveDirectly()` sets it) — `open()` now records the placeholder it wrote in `placeholderPath` and the discard unlinks only that tracked path; `handlePartial()`'s catch checks liveness before re-asking and rolling back a second time after a cancellation; the metadata retry is gated on `taskApiConfigReadySettled` rather than on the api-config value, so legacy history tasks still get it; the two `keeps approved diff content` tests gained the assertion that can actually fail; the `teardownAbandonedStream` JSDoc is attached to its method.	6 files, +191 / −30
`d9843bd30`	The `3a0065091` review: the dispose-time metadata retry moved behind `disposeOnce()`'s synchronous teardown (it had become the first await, so `abortTaskOnce()` could await the placeholder `diffReversionPromise`, an abandoned stream could skip the revert decision, and direct `dispose()` callers lost the synchronous abort flag); its unreachable `try/catch` removed (that was the mutation-diff `NoCoverage` advisory); and the placeholder-ownership lifecycle gained public-method coverage for `open()` and `saveChanges()`.	3 files, +133 / −15
`aa959bf12`	Test-only: the ENOENT-tolerance test now creates two directories, keys the injected failure on the path rather than on call order, and asserts both paths were attempted (a series rule: an fs function called on several paths in one flow must be mocked by path, not by position).	1 file, +19 / −3

Local run at aa959bf12: core/tools 677 passed / 5 skipped, core/task 690 passed, core/assistant-message 101 passed, integrations/editor 90 passed (plus the pre-existing local-only saveChanges … default values failure that is green in CI), tsc --noEmit 0 errors, eslint clean on every touched file with src/eslint-suppressions.json unchanged. Each fix above is pinned by a negative control; see the evidence comments on the review threads and issuecomments 6067423020 / 6068252476. zdt split verify PASS (both files byte-identical to the content source of record). Unit tests: 264 passed / 5 skipped, exit 0; changed-line coverage 12 covered / 0 uncovered — PASS; ESLint clean, suppression counts unchanged.

Closes #1938 (unit U7 of the upstream PR 1066 split).

Round update — Lifecycle Resource Cleanup: the argued row is now actually fixed

Shared root cause behind the Lifecycle Resource Cleanup row (all five units of 1066). handlePartial() registers this task's partial-stream entry — and its TaskAborted listener — before it checks the prevent-focus-disruption experiment. With the experiment enabled the delta returns without ever showing a preview and never reaches execute()'s teardown, so the entry and the listener stay attached for the rest of the task's life, and a streamFailed mark armed by an earlier failed delta keeps suppressing this task's later diff previews. The sibling units carry the same release in their own PRs, each verified red-first with a negative control.

This unit (U7): execute() was already covered by the finally { this.resetTaskPartialState(task) } block — that is what my earlier argument rested on. The one exit that skipped a teardown was the suppressed-preview return in handlePartial(); it now releases the entry and detaches the listener.

Red first: the new test failed with expected 1 to be +0 (the entry was still in the map after the delta returned). Green: 67 passed / 5 skipped. Negative control: removing the two release lines turns exactly that one test red; restored green.

Main refresh. Merged org main 036245c5e (U1 1927). U1's content no longer appears in this diff: 14 files +3389/−46 → 13 files +2946/−51, 0 behind main. Conflicts were confined to src/core/task/__tests__/Task.spec.ts (and Task.ts on U7) — the region U1 rewrote; resolved by taking main's version of the shared save-stage tests (try/finally plus the fixed-task-id ui_messages.json cleanup from cf9206a42) rather than re-implementing U1.

Verification after the merge: Task.spec 176 passed, writeToFileTool.spec 67/5, DiffViewProvider.spec 84, presentAssistantMessage specs 3 + 20, eslint 0/0 on every touched file.

Rows from the at-head assessment (2026-10-09)

Fix commit 1e6828073 (base a244ef55b).

Persistence Integrity - the dispose-time metadata retry now runs when taskApiConfigReadySettled is true or _taskApiConfigName is already defined: persistTaskMetadata() awaits the promise only while the name is undefined, so once it is known the retry cannot block teardown and skipping it leaves the history entry behind messages already on disk. Regression test covers exactly that combination.
Lifecycle Resource Cleanup - handlePartial()'s pre-streaming awaits (provider state, filesystem probe, directory creation, partial ask) are inside a boundary that releases this task's stream state and rethrows, so BaseTool.handle() still reports the error once; partialMessage is hoisted because the diff-view catch finalizes the same ask.

Negative controls: retry condition back to settled-only -> exactly the metadata test red; boundary teardown off -> exactly the handlePartial test red; rethrow off -> exactly the same test red. Verification: 384 passed, tsc 62 (baseline), eslint 0/0, suppressions unchanged.

Review round (maintainer review, 2026-10-28)

Head e2e6604e7.

teardownAbandonedStream() finalized nothing on the three presenter bypass exits (0d098d0ca). A streamed delta's partial tool ask (partial: true) stayed open, so the webview spinner kept running for a call already reported as failed. The teardown now finalizes the ask after its has() guard, matching the missing-parameter, rooignore, and parse-failure exits. Pinned by writeToFileTool.spec.ts; removing the call turns the assertion red.
The abort teardown reverted instead of discarding (e2e6604e7). abortStream() called revertChanges() unconditionally, so a cancelled create SAVED the dirty buffer - the unapproved partial model output - before unlinking the placeholder. Disposal and the abort teardown now share Task.releaseUnapprovedDiffView(): the edit type picks the mechanism, and the stored promise is the single owner, so a release one path started is awaited by the other rather than rolling the same view back twice. The promise is cleared at the next request's diff-view reset.
Pinned by Task.spec.ts (create abort discards, modify abort reverts, shared promise, no-open-view no-op, disposal-after-abort does not roll back again). Negative controls: abortStream back to revertChanges() -> create abort test red; owner guard removed -> shared-promise test red.

Verification at e2e6604e7: core/tools 83 passed / 5 skipped, core/task (Task.spec + Task.dispose) 224 passed, core/assistant-message missing-native-args 1 passed, removeClineFromStack-delegation 1 passed, integrations/editor 87 passed (all seven affected suites were run together: 397 passed / 5 skipped), tsc --noEmit 0 errors, eslint --max-warnings=0 clean on all four touched files with src/eslint-suppressions.json unchanged.

Main refresh (2026-10-28)

Merged upstream/main 3f51e9df7 (e2f5d1c3), 0 behind main. The refresh brought three contract changes the unit had to follow: presentAssistantMessage() now requires a RequestPolicySnapshot and the per-call activeToolContexts map, the repetition detector returns a tagged union (allow / soft_block / hard_block), and ToolCallbacks.toolCallId is required. The abandoned-stream spec now supplies the snapshot/map and stubs the hard-block exit it tests; the four hand-built callback literals pass toolCallId; BaseTool.onParameterParseFailure's unused params are underscore-prefixed for main's lint rule and the cleanup spec's unused helper is gone.

Verification after the merge: seven affected suites 422 passed / 5 skipped, pnpm lint 11/11, tsc --noEmit 0, and every file this PR changes is prettier-clean under the new format:check step.

Summary by CodeRabbit

Bug Fixes
- Improved recovery when file-writing operations are interrupted or fail, including cleanup of incomplete edits and temporary files.
- Prevented unapproved streamed changes from being left behind, while preserving edits that have already been approved.
- Ensured failed or incomplete file-writing requests are finalized cleanly, even when cleanup steps encounter errors.
- Improved task cleanup and retries for saving task details after a persistence failure, without delaying teardown while a retry is pending.

📝 Summary

Walkthrough

The changes add per-task cleanup for partial write streams and abandoned editor content. Task saves distinguish message-write success from metadata persistence and retry pending metadata repairs during disposal.

Changes

Task metadata repair

Layer / File(s)	Summary
Record and retry metadata failures `src/core/task/Task.ts`, `src/core/task/__tests__/Task.spec.ts`	Task saves retain their message-write result when metadata persistence fails. Disposal retries pending repairs according to API-configuration initialization state. Tests cover retry timing and missing-provider behavior.
Apply task cleanup during disposal `src/core/task/Task.ts`, `src/core/task/__tests__/Task.dispose.test.ts`, `src/core/task/__tests__/Task.spec.ts`, `src/__tests__/removeClineFromStack-delegation.spec.ts`	Task disposal clears write-tool state and distinguishes discarding a create preview from reverting a modify preview. Tests cover cleanup and diff-teardown ordering.

Partial write lifecycle

Layer / File(s)	Summary
Discard unapproved editor content `src/integrations/editor/DiffViewProvider.ts`, `src/integrations/editor/__tests__/DiffViewProvider.spec.ts`	DiffViewProvider tracks edit-owned placeholders and created directories. Discard restores dirty buffers and removes tracked artifacts. Tests cover ownership and cleanup failures.
Track and recover write streams `src/core/tools/BaseTool.ts`, `src/core/tools/WriteToFileTool.ts`, `src/core/tools/__tests__/*`, `src/eslint-suppressions.json`	BaseTool finalizes partial asks after parse failures and provides a recovery hook. WriteToFileTool tracks streams per task and cleans up after failures, cancellation, and approval paths. Tests cover stream recovery, rollback, and directory creation.
Tear down abandoned streams `src/core/assistant-message/presentAssistantMessage.ts`, `src/core/assistant-message/__tests__/presentAssistantMessage-missing-native-args.spec.ts`, `src/core/webview/ClineProvider.ts`	Assistant-message failure paths tear down abandoned write streams. Failed history-task cleanup clears tool state before task disposal. Tests cover these cleanup paths.

Full details: Linked Issues check

Explanation

[#1938] WriteToFileTool finalizes the partial ask and clears per-task state on missing-parameter and rooignore-denial paths. The implementation also removes unapproved streamed content before reset. The added tests cover state cleanup, ask finalization, and denied or truncated writes. The reported verification covers the required suites, coverage, and ESLint checks.

Full details: Out of Scope Changes check

Explanation

The additional Task, DiffViewProvider, presenter, provider, and test changes support the documented split integration and shared partial-stream lifecycle. They prevent stale state, unsafe persistence of unapproved content, duplicate error handling, and disposal leaks. No concrete unrelated change is demonstrated.

Full details: Regression Evidence

Explanation

PASS. The changed cleanup and lifecycle behaviors have focused unit coverage at the relevant layers. writeToFileTool.spec.ts covers missing path and content, rooignore denial, parse failure, streaming failure, cancellation races, approval states, and reset failures. presentAssistantMessage-missing-native-args.spec.ts covers missing native arguments, validation denial, and repetition denial. DiffViewProvider.spec.ts directly covers create and modify discard behavior, buffer restoration, artifact ownership, cleanup errors, ENOENT, and approved-file protection. Task.spec.ts, Task.dispose.test.ts, and removeClineFromStack-delegation.spec.ts cover metadata retry, unsettled configuration, create-versus-modify disposal, and direct disposal cleanup. No durable frontend component changed, so a Playwright component snapshot is not applicable. The tests assert outcomes and failure handling, not only implementation calls.

Full details: Security Boundaries

Explanation

No changed path bypasses the write approval or .rooignore checks. WriteToFileTool.execute() still calls validateAccess(relPath) before either approval branch, and it calls saveDirectly() or saveChanges() only after askApproval() returns approval. The new missing-argument, validation-failure, and repetition paths only call teardownAbandonedStream() and do not execute the tool. That teardown uses discardUnapprovedStream(): it does not save modification content, and it empties a newly created placeholder before cleanup. The diff provides no concrete changed path that leaks secrets or PII, executes unvalidated input, or bypasses approval or allowlist controls.

Full details: Persistence Integrity

Explanation

No changed persistence path meets the failure condition. Task.saveClineMessages() awaits saveTaskMessages() and then awaits persistTaskMetadata(); persistTaskMetadata() awaits updateTaskHistory() and records failures for one awaited retry in disposeOnce(). DiffViewProvider.discardUnapprovedStream() awaits buffer restoration and artifact removal, preserves placeholder ownership, and reports editor or cleanup failures. The changed code also propagates the initialized API config name or the documented legacy undefined value to taskMetadata(). I found no changed unawaited write, missing rollback, or missing default propagation.

Full details: Title check

Explanation

The title clearly identifies the primary write-to-file cleanup change and the integration scope. It is longer than preferred and includes series metadata, but it remains specific and related to the changes.

Full details: Description check

Explanation

The description links issue #1938, explains the implementation and review-sensitive behavior, and provides extensive test and verification results. It does not use the repository template headings or include the completed pre-submission checklist, documentation section, and contact details, but the required issue, change summary, and testing information are present.

Full details: Lifecycle Resource Cleanup

Explanation

Cancellation during DiffViewProvider.open() can leak the diff editor and its listeners. open() sets isEditing = true and then awaits openDiffEditor(); after that await it assigns activeDiffEditor and registers the editor listeners at DiffViewProvider.ts:185-258. The changed Task.dispose() path calls discardUnapprovedStream() while that await is pending. Because activeDiffEditor is still undefined, discardUnapprovedStream() skips editor cleanup, then clears isEditing and provider fields at DiffViewProvider.ts:653-659. When openDiffEditor() later resolves, open() installs activeDiffEditor and the listeners but does not restore isEditing. The changed handlePartial() then calls discardDiffViewOpenedAfterRelease(), which returns immediately when isEditing is false at WriteToFileTool.ts:290-292. The late diff editor and listeners remain attached after task cancellation.

Resolution

Make abandoned-stream cleanup own pending open() completions. Track an open-generation or cancellation token and check it after await openDiffEditor() before publishing activeDiffEditor or registering listeners. If the stream was released, close/dispose the returned editor and dispose all temporary listeners and timers. Do not use isEditing as the only guard, because disposal clears it before the pending open() continuation settles.

Make revertChanges() discard unapproved new-file content before deletion.

When revertChanges() handles a new file, it saves the dirty buffer before calling fs.unlink. If the unlink fails, rejected or cancelled partial content remains on disk.

The approval-denial path in WriteToFileTool.execute() and the cancellation paths in Task call revertChanges() directly. Update the new-file branch in revertChanges() to clear the buffer before saving, or delegate to discardUnapprovedStream(), so these callers cannot persist unapproved content.

…n and guard pre-stream setup Addresses the two Zoo-Code-Org#1066/U7 checklist rows on the at-head assessment (a244ef5): - Persistence Integrity (error): the dispose-time metadata retry ran only when taskApiConfigReadySettled was true. persistTaskMetadata() awaits that promise only while _taskApiConfigName is still undefined, so once the name is known (handoff, resumed history item, setTaskApiConfigName) the retry cannot block teardown and skipping it leaves the history entry behind messages already on disk. The condition is now pendingTaskMetadataRepair && (taskApiConfigReadySettled || _taskApiConfigName !== undefined). - Lifecycle Resource Cleanup (warning): handlePartial() registers the per-task stream state and its TaskAborted listener, then awaits provider.getState(), the filesystem probe and the partial ask with no cleanup path. Those awaits are now inside a boundary that releases this task's state and rethrows, so BaseTool.handle() still reports the error once. partialMessage is hoisted above the boundary because the diff-view catch finalizes the same ask. Red first: both new tests failed before the fixes. Negative controls: condition back to settled-only -> exactly the metadata test red; teardown call removed from the new catch -> exactly the handlePartial test red; rethrow removed -> exactly the same test red. Verification: Task.spec 177, writeToFileTool 68/5s, partial-state-cleanup, DiffViewProvider - 384 passed; tsc 62 (baseline, none in touched files); eslint 0/0; eslint-suppressions unchanged.

Add the success-path negative case for cleanupFailedPartialStream.

No test asserts that a successful rollback reports no hazard. If if (!reverted) at WriteToFileTool.ts Line 210 became unconditional, every test in this file would still pass. Add a test in which discardUnapprovedStream resolves. It should assert that say is not called.
it("does not report a rollback hazard when the failed-stream cleanup succeeds", async () => {
	const task = buildTask("failed-stream-cleanup-ok", "inst-12")
	const t = task as unknown as CleanupTask

	await writeToFileTool["cleanupFailedPartialStream"](task)

	expect(t.diffViewProvider.discardUnapprovedStream).toHaveBeenCalledTimes(1)
	expect(t.diffViewProvider.reset).toHaveBeenCalledTimes(1)
	expect(t.say).not.toHaveBeenCalled()

Assert that the abort listener removed is the same reference that was registered.

Line 1803 still uses expect.any(Function). That assertion passes even if a different function is detached. Capture the listener from mockCline.once, as the sibling tests do, and assert that exact reference in the off call.

As per path instructions: "For listener registration and removal, assert the same function reference was added and removed (not expect.any(Function))."

The test name says "does not finalize the ask", but the test never checks finalizePartialToolAsk.

finalizePartialToolAskAfterFailure calls task.finalizePartialToolAsk, not task.ask. The assertion at Line 603 counts ask calls, so it cannot detect a finalize call. Clear the mock before the delta and assert it was not called.

Check the applyEdit result before the code saves the abandoned buffer.

vscode.workspace.applyEdit() resolves to false when VS Code does not apply the edit. Line 578 ignores that result, and Line 579 then calls document.save(). In that case the buffer still holds the streamed partial content, and save() writes that unapproved content to the placeholder. If the later fs.unlink fails with an error other than ENOENT, the content stays on disk. This is the hazard the method is meant to prevent.
Proposed fix
 					edit.replace(document.uri, fullRange, "")
-					await vscode.workspace.applyEdit(edit)
-					await document.save()
+					const applied = await vscode.workspace.applyEdit(edit)
+					if (!applied) {
+						throw new Error("Failed to blank the abandoned write_to_file buffer")
+					}
+					await document.save()
Add a test in which applyEdit resolves false. It should assert three things: document.save is not called, fs.unlink still runs, and the promise rejects.

…s diff view CodeRabbit Security Boundaries on Zoo-Code-Org#1928: the rooignore-denial cleanup released the diff view through revertChanges(), which SAVES. For a modify that writes the restored original content to a path the policy had just refused; for a create it persists the dirty partial buffer before deleting the file, so a failed delete leaves unapproved bytes on disk. discardUnapprovedStream() now covers both edit types: a create buffer is emptied before anything can reach the file, a modify buffer is restored to the content already on disk in memory only, and the target file is never written. The restore is checked - if applyEdit does not apply, the save is skipped (saving then would persist exactly the content being discarded) and the failure surfaces to the caller as the rollback hazard it is. CodeRabbit Lifecycle Resource Cleanup on Zoo-Code-Org#1928: the TaskAborted teardown can only release the diff view that existed when it ran. When open() settles AFTER the release it publishes a view nobody owns - for a create, the placeholder plus the directories open() wrote - and execute() never runs for a cancelled stream. handlePartial() now runs an idempotent abandoned-view cleanup at both settle points around open(), and Task disposal releases a cancelled create the same way instead of saving it. CodeRabbit Persistence Integrity on Zoo-Code-Org#1928 (first half): persistTaskMetadata() read the provider through an optional chain, so a released provider turned the two history writes into no-ops that reported success and CLEARED pendingTaskMetadataRepair. A missing provider is now treated as the failed stage it always was and the flag stays set for the disposeOnce() retry. The in-flight tracking half is filed on the plan issue as a follow-up with acceptance criteria. Negative controls (Buffer snapshot + sha256 verified after every mutant): - restore always empty / modify saved again / applyEdit result ignored -> exactly the matching DiffViewProvider test red (1 each). - settle-site cleanup removed -> 1 red; idempotency guard removed -> 2 red; modify routed back to revertChanges -> the 2 routing tests red. - provider guard removed -> 1 red; disposal always reverts -> 1 red. Local: DiffViewProvider 86 passed; writeToFileTool + partial-state-cleanup 82 passed (5 skipped); Task.spec 180 passed; Task.dispose 14 passed; broad sweep (core/tools, integrations/editor, core/task, services/mcp) 72 files / 1544 passed; tsc --noEmit 0 with the local @roo-code/types paths override; eslint . --ext=ts --max-warnings=0 exit 0; eslint-suppressions.json untouched.

1866-1866: The test still uses expect.any(Function) for the off assertion.

An earlier review asked for this and it was marked addressed in 1e68280. The current code still checks off with expect.any(Function). The test passes even if the code removes a different function, so the TaskAborted listener from getTaskPartialStreamState() could stay attached.

Fix: Capture the listener from mockCline.once, as the sibling tests at Lines 291-297 do. Then assert that exact reference.
Proposed fix
 			enablePreventFocusDisruption()
+			let abortCleanup: (() => void) | undefined
+			mockCline.once.mockImplementation((event: RooCodeEventName, listener: () => void) => {
+				if (event === RooCodeEventName.TaskAborted) {
+					abortCleanup = listener
+				}
+				return mockCline
+			})
 ...
-			expect(mockCline.off).toHaveBeenCalledWith(RooCodeEventName.TaskAborted, expect.any(Function))
+			expect(abortCleanup).toBeTypeOf("function")
+			expect(mockCline.off).toHaveBeenCalledWith(RooCodeEventName.TaskAborted, abortCleanup)
As per path instructions: "For listener registration and removal, assert the same function reference was added and removed (not expect.any(Function))."

A cancelled stream could still do work after its owner was gone, in three places: - handlePartial() re-checked stream identity before awaiting diffViewProvider.update() but not after. When the abort landed inside that await, the continuation returned as if it still owned a live stream. It now re-checks and hands off: the view it streamed into already existed when the TaskAborted teardown ran, so that teardown owns it - the continuation waits for the disposal's own reversion (new Task.waitForDiffReversion) instead of starting a second discard over the same buffer, then drops the provider references the released stream points at. - discardUnapprovedStream() left isEditing set and the diff editor referenced. A task disposed while streaming runs that discard with no reset() after it, so the disposed task kept a live diff view and a late continuation still read a session as open. - The per-task stream state lives in a tool singleton and was released only by the TaskAborted listener registered with it, or by the one provider path that calls clearTaskState(). dispose() removes every listener, so a direct disposal kept the entry, the task, and its provider forever; the release now sits on the path every disposal takes, next to the listener teardown. Three regression tests, one per defect, each killing exactly that fix. The spec file also picks up the indentation prettier wants: the committed copy of the discardUnapprovedStream block is one level deep, and the repository lost its .prettierignore on main, so the whole-repo format check now reaches it.

The repository's ignore list no longer covers them, so the format job reads them as committed: two carry CRLF line endings and one has wrapped arguments prettier wants unfolded. Content is untouched - the same 195 tests pass before and after.

3618-3623: 🩺 Stability & Availability

The inspected implementation does not establish a non-settling production dependency. TaskHistoryStore is created without an onWrite callback (src/core/webview/ClineProvider.ts:353-355), its lock acquisition has finite retries (src/utils/fileLock.ts:18-40), and postMessageToWebview() only awaits the VS Code webview operation before catching errors (src/core/webview/ClineProvider.ts:1470-1480). The code proves that an actually pending metadata retry would delay disposeOnce(), but it does not prove that updateTaskHistory() can remain pending. The proposed Promise.allSettled change would not fix that case because allSettled also waits for the pending retry.

Every path through the try/catch already reports this stage's result: false when the provider is gone, false from the catch, true after the history entry is written. The trailing return could never run, and it contradicted the contract the method now documents. No behaviour changes - which is also why no test moves when it comes back.

已照現在程式碼查證，並移除。

persistTaskMetadata() 的三條路徑都已經各自回報這一階段的結果：provider 已釋放時 return false（:1828-1832）、catch 裡 return false（:1837-1844）、寫完 history entry 後 return true（:1836）。尾端那行 return true 確實永遠到不了，而且跟這個方法現在文件化的契約（每條路徑顯式回報）互相矛盾。

誠實記錄：沒有加測試。這行是不可達程式碼，把它放回去 Task.spec.ts 的 180 條測試全數照綠（我實際跑過），所以沒有任何測試能區分它；同一位置那顆存活的 BooleanLiteral 變異體講的是同一件事的另外一面。此處屬於清理，不是行為修正。

同一個檔案這輪另外帶了兩處（來自 Lifecycle 那條檢查）：新增 waitForDiffReversion() 讓觀測到自己 stream 被釋放的續作等 disposal 已開始的那次還原，而不是對同一個 buffer 再跑一次獨立的 discard；以及把 writeToFileTool.clearTaskState(this) 放進 disposeOnce() 移除監聽器旁邊——直接呼叫 dispose() 的路徑不再把 stream 狀態留在工具單例裡。

…m exit The presenter bypass exits (missing nativeArgs, validateToolUse denial, tool repetition) route an abandoned block to teardownAbandonedStream() instead of handle()/execute(), so the partial ool ask a streamed delta opened was never finalized: the webview spinner kept running for a call the presenter had already reported as failed. The missing-parameter, rooignore and parse-failure exits already finalize the same ask, so the teardown does it after its has() guard; the guard comes first so an unrelated ask cannot be closed for a task that never streamed.

…wn and disposal abortStream() reverted the open diff view unconditionally, so a cancelled create saved the dirty buffer - the partial model output nobody approved - before deleting the file; a failed delete left it on disk. revertChanges() was the same hazard disposal had already fixed, and a release one path started could be repeated by the other over the same view. Both paths now share releaseUnapprovedDiffView(): the edit type selects the mechanism (modify reverts the content already on disk, create discards the buffer before removing the placeholder) and the stored promise is the single owner, so a later caller awaits the release already in flight instead of starting a second rollback. The promise is cleared at the next request's diff-view reset, because each request opens a new diff-view session. Tests pin the create and modify abort branches, the single-owner promise, the no-open-view no-op, and disposal-after-teardown; negative controls: reverting abortStream to revertChanges() turns the create test red, dropping the owner guard turns the shared-promise test red.

…-callback contracts The main refresh brought three contract changes this PR's files had to follow: - presentAssistantMessage() now takes a required RequestPolicySnapshot and the per-call activeToolContexts map, and the repetition detector returns a tagged union (allow / soft_block / hard_block). The abandoned-stream spec now passes an empty policy snapshot, seeds activeToolContexts, and stubs the hard block exit it is testing. - ToolCallbacks.toolCallId is required, so the four hand-built callback literals in writeToFileTool.spec.ts pass it. - BaseTool.onParameterParseFailure's default implementation kept three unused parameters, which main's lint rule now flags: they are underscore-prefixed. The unused stateFor helper in the cleanup spec is removed for the same reason. Verification: seven affected suites 422 passed / 5 skipped; eslint --max-warnings=0 clean on every touched file; tsc --noEmit 0 errors; pnpm lint 11/11 tasks.

@coderabbitai review

The maintainer's two review threads are addressed and the branch is refreshed onto main (head 09a03a7b). Changes since the last review: the abandoned-stream teardown now finalizes the open partial ask; disposal and the stream abort teardown share one single-owner diff-view release (a cancelled create is discarded, never reverted); main-contract adaptations (policy snapshot, tagged repetition union, required oolCallId, lint rules). Both threads are replied to and resolved; each fix is pinned by a negative control.
