📝 Summary
Merge Risk: 🟡 Moderate · up to Most write tools now go through the guard. However, previously reported issues remain unconfirmed as fixed, including an apply_patch move in which the destination may bypass the read-before-write guard. That bypass could overwrite a file that was never read. Resolve or explicitly accept these issues before merging. Caution Pre-merge checks failedPlease resolve all errors before merging. Addressing warnings is optional.

…ve (U1, issue 1375) Split unit U1 of PR 1833. Three changes, each with a test that fails without it: - a caller-supplied staging path is checked for location and file type before anything is written, so an arbitrary path or a symlink cannot be published onto the target; - a failed parent-directory fsync on POSIX is reported as PostCommitDurabilityError instead of being swallowed, so a successful return never claims durability the filesystem did not grant; - the staged file and this write's own staging directory are released before RollbackFailureError is thrown. Focused coverage for resolveLockKey added: canonical parent directory, a dangling-link chain, and termination at the bounded depth on a two-link cycle.

…ishTarget (U1, issue 1375) The resolver may fall back to the given path only when lstat also reports the path as absent. An EACCES or EIO failure says nothing about whether the path is a link, so falling back would publish through a link we were not allowed to inspect. Focused tests added for both branches.

… type-sound
compile failed at the unit head on three points:
- RollbackFailureError needs a string backupPath, but the throw now happens after cleanup, so the
`string | null` narrowing was lost. The failure is now held as { error, backupPath }.
- The async lstat stand-in is built on the Stats prototype so it satisfies fsSync.Stats.
- The realpath/readlink mocks are typed to the real signatures; the readlink mock answers once
because only the link path is read.
tsc clean, 50 tests pass, ESLint --max-warnings=0 clean, no suppression change.

The any usage this entry covered is gone in the rewritten file, so the count drops 4 -> 3. eslint --prune-suppressions --max-warnings=0 confirms it.
The read tools record the observed on-disk version through task.observationRegistry, but the field was only declared in a later unit, so at this head the call dereferences undefined and the mocked e2e run fails on the read_file smoke tests. The registry is introduced by this unit, so the field belongs here. tsc clean on this unit, 11 observationRegistry tests pass, ESLint --max-warnings=0 clean.
The two any usages this entry covered are gone in the rewritten spec, so the count drops 98 -> 96. eslint --prune-suppressions --max-warnings=0 confirms it.

U6's ApplyPatchTool calls saveChanges with the writeKind argument, so the parameter must exist before U6 can build. U8 owns that signature, so U8 now lands before U6.
…rror handling
The outside-workspace identity capture sat before the try block of the write flow, so a
target that could not be resolved threw past the tool: no handleError, no diff-view
reset, and the failure escaped a path that is supposed to report it to the model like
any other write failure.
The capture now sits at the top of that try block - still before askApproval, so the
approval is still bound to an identity captured ahead of it, and a path that cannot be
resolved is never put in front of the user at all.
Test: an outside-workspace target whose resolution fails reaches handleError("writing
file", ...), resets the diff view, and publishes nothing. Negative control measured in
this harness: moving the capture back outside the try -> 1 failed, with the
GuardRejectedError escaping the tool instead of being handled. Restore byte-identical.
Baseline after the sweep: 354 passed / 5 skipped across the nine affected specs (u7),
355 / 5 (u9); tsc at its pre-existing 50-error baseline; eslint --max-warnings=0 clean;
src/eslint-suppressions.json untouched.
Two review findings about the tests added for the approved-identity work: - The outside-workspace forwarding tests reset the isPathOutsideWorkspace module mock after their assertions, so a failing assertion would leave the flag true and the tests that follow would fail for the wrong reason. The reset now sits in a finally block. - The failed-delete test in the delete-semantics spec carried its explanation next to the assertions while the seeding it describes happens above the delete. The comment now points back at that seeding instead of implying it happens at the assertions. Measured in this harness: with the assertion inside the wrapped test broken on purpose, the file still reports exactly one failure - the flag leak does not currently surface as a wrong-cause failure in these four specs. The reset is moved for the failure path, not because a cascade was reproduced. Baselines after the sweep: 370 passed / 5 skipped across the ten affected specs (u9), 354 / 5 (u7); tsc at its pre-existing 50-error baseline; eslint --max-warnings=0 clean on every touched file; src/eslint-suppressions.json untouched.

🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy liftThe diff-view move path still writes the destination without the guard.
When
preventFocusDisruptionis off, a*** Move to:patch writes the destination withfs.mkdirandfs.writeFile(Lines 537-539). This path does not callguardedWrite. TheisPreventFocusDisruptionEnabledbranch above now publishes the same destination withsaveDirectly(..., "create", sourceComplete, ...). That branch rejects an existing destination that the model never read. It also carries the source completeness and checks for a stale version.The two save modes therefore enforce different rules for the same patch. Trigger: the destination exists and the model has not read it. The model sends a move patch, the user approves it, and diff view is active. Consequence: the existing destination is overwritten without a read. No stale-version check and no per-path serialization run. This conflicts with the PR objective, which says
apply_patchroutes its writes through the shared guarded-write path. Theensure-observedand partial-source checks at Lines 485-522 also run only in the focus-disruption branch.Route both branches through one guarded publish. Move the completeness carry and destination checks out of the
if. Then callsaveDirectlyfor the destination in both modes. That call already passesadditionalRootsand the create guard.Proposed fix
- // Save new content to the new path - if (isPreventFocusDisruptionEnabled) { - const sourceObs = task.observationRegistry.get(absolutePath) - ... - await task.diffViewProvider.saveDirectly( - change.movePath, - newContent, - false, - diagnosticsEnabled, - writeDelayMs, - "create", - sourceComplete, - isPathOutsideWorkspace(moveAbsolutePath), - moveCanonicalTarget, - ) - } else { - // Write to new path and delete old file - const parentDir = path.dirname(moveAbsolutePath) - await fs.mkdir(parentDir, { recursive: true }) - await fs.writeFile(moveAbsolutePath, newContent, "utf8") - } + // Both save modes publish the destination through the guard. + const sourceObs = task.observationRegistry.get(absolutePath) + // ...existing completeness carry / destination checks, unchanged... + if (!isPreventFocusDisruptionEnabled) { + // Close the source preview opened above before publishing elsewhere. + await task.diffViewProvider.revertChanges() + } + await task.diffViewProvider.saveDirectly( + change.movePath, + newContent, + false, + diagnosticsEnabled, + writeDelayMs, + "create", + sourceComplete, + isPathOutsideWorkspace(moveAbsolutePath), + moveCanonicalTarget, + )Add a diff-view move test. The test sets a destination that exists without an observation. It then asserts that the publish is rejected and that
fs.writeFileis not called.🤖 Prompt for AI Agents

File: src/services/file-safety/safeWriteText.ts:410-427
Timestamp: 2026-10-06T00:19:25.595Z
Learning: In src/services/file-safety/safeWriteText.ts, the TypeScript safeWriteText API intentionally requires confirmed directory-entry durability for a successful POSIX return. Directory-open or directory-fsync failures, including EINVAL, ENOTSUP, EISDIR, and EPERM, must produce PostCommitDurabilityError after the commit rather than be ignored. The error identifies the target containing the committed content. When backup mode is enabled, retaining the old-content backup on this failure path is intentional recovery behavior; do not recommend deleting it merely because the commit rename succeeded.

Timestamp: 2026-10-06T00:19:38.801Z
Learning: In the TypeScript Windows write path in `src/services/file-safety/safeWriteText.ts`, DACL preservation is intentionally best-effort. `_saveDaclWindows` failure must not prevent publication, because `icacls` can fail on non-NTFS mounts or in permission-restricted environments. `_restoreDaclWindows` failure is non-fatal after commit. Do not require fatal DACL handling or rollback of committed content under this contract.

Timestamp: 2026-10-08T09:38:50.043Z
Learning: In Zoo-Code-Org/Zoo-Code, Task.cwd identifies one workspace root, while write tools use isPathOutsideWorkspace(absolutePath) to classify paths against all VS Code workspace folders. A target in another workspace folder can therefore be outside Task.cwd while isPathOutsideWorkspace returns false. Write authorization must distinguish this case from an explicitly approved path outside all workspace folders.

Timestamp: 2026-10-06T00:19:36.133Z
Learning: In Zoo-Code, DiffViewProvider.open in src/integrations/editor/DiffViewProvider.ts intentionally records a stat-matched preview observation with complete: false for an unread existing file. The edit guard accepts this partial observation; this policy is documented and asserted. Do not treat that acceptance alone as an unintended authorization bypass. The separate question of whether the preview token is a valid baseline for previously constructed edit content requires a cross-unit maintainer decision.

File: src/core/tools/guardedWrite.ts:330-344
Timestamp: 2026-10-08T09:56:55.708Z
Learning: In Zoo-Code-Org/Zoo-Code, the TypeScript guardedWrite API in src/core/tools/guardedWrite.ts keeps core host-agnostic: extension-host callers supply other VS Code workspace folders through GuardedWriteOptions.additionalRoots. GuardedWriteOptions.approvedOutsideWorkspace represents a post-approval authorization, not path classification. ApplyDiffTool in src/core/tools/ApplyDiffTool.ts has no outside-workspace approval flow, so it must not receive that authorization merely because its target is outside the workspace.

123-151: Add a timeout to theicaclssave and restore calls.A previous review asked for this, and the current code still does not do it. Neither
execFilecall sets atimeout. On Windows,safeWriteJsonwaits for both calls while it holds the advisory file lock. If oneicaclschild process stalls, this write blocks, and so does every other writer of the same file. DACL handling is best-effort, so a timeout would just returnfalseand use the existing warning path. Passingtimeoutin the options object is enough.Proposed fix

… a teardown it does not own Port of `0974ad534` (U8, Zoo-Code-Org#1916) to U7. Same defect, open on four units at their current heads - Zoo-Code-Org#1915 (U6), Zoo-Code-Org#1916 (U8), Zoo-Code-Org#1917 (U9), Zoo-Code-Org#1918 (U7, this PR) - and DiffViewProvider.ts already carries four distinct blobs across those heads (82b5857 / 44049b5 / 854569b / 15f032a). Authored once in the unit that owns the save-gate teardown and ported in the declared merge order U1 U2 U3 U4 U5 U8 U6 U7 U9, so the blob table on #41 traces every copy back to `0974ad534`. Task.disposeOnce() can reach revertChanges() while saveChanges() owns its post-publish teardown. runTeardown() made the caller a waiter and returned false, revertChanges() then skipped its finalization, and the save's own pass closes the views and restores the tabs but never resets - the tool caller that owns the provider lifecycle may never come back after a disposal. The provider was left with isEditing true and activeDiffEditor retained. - runTeardown() records that a cancellation is waiting on the pass that owns the session. - saveChanges() reports no completed save when a cancellation landed during its post-publish pass, instead of running diagnostics and the EOL/patch tail against provider state (newContent, relPath) that the finalization clears. - revertChanges() closes the session after the owning pass returned, when that pass did not. Port adaptations for this unit (this branch's runTeardown takes a second `finalize` argument, which U8's does not): - The finalization decision is a recorded flag, `teardownPassResets`, set inside revertChanges()'s own finalize step and cleared when a pass starts - not U8's `isEditing || activeDiffEditor` state check. On this branch the rejected save's discard pass also passes a finalize (it restores the preview tabs but does not reset), so "has a finalize step" is not the same question as "closes the session", and a state check would let a waiter reset a session the owner had already closed. - No `ownedTeardown` result check exists in this unit's saveChanges(), so the source commit's `!ownedTeardown` block was not ported; only the cancellation bail-out was added there. Verification on this unit: red first with the production hunks absent and the tests ported -> 4 failed | 141 passed. Green -> 145 passed. Negative control: removing the waiter finalization -> 4 failed | 141 passed, production file restored byte-exactly, post-restore run 145 passed. tsc --noEmit 50 errors, identical to this branch's baseline and 0 in the touched files; eslint --max-warnings=0 clean on both files; src/eslint-suppressions.json untouched.

- Around line 354-373: Update the “records no observation when the post-read
stat fails” test so the pre-read stat succeeds and only the post-read stat
rejects. Use the mocked readFile call to distinguish the two stat calls,
preserving the assertions that no observation is recorded and the save falls
back to remediation.

- Around line 685-726: Add a POSIX-only regression test alongside “rejects an
out-of-scope target before the advisory lock is taken” using an in-scope
dangling symlink to an outside referent; assert the write rejects with
ReimportedError, lockCalls stays empty, and no lock file appears beside the
referent. Correct the existing test’s comment to identify the pre-mkdir check as
the check that rejects its target.

Repo: Zoo-Code-Org/Zoo-Code PR: 1918
File: src/services/file-safety/safeWriteText.ts:410-427
Timestamp: 2026-10-06T00:19:25.595Z
Learning: In src/services/file-safety/safeWriteText.ts, the TypeScript safeWriteText API intentionally requires confirmed directory-entry durability for a successful POSIX return. Directory-open or directory-fsync failures, including EINVAL, ENOTSUP, EISDIR, and EPERM, must produce PostCommitDurabilityError after the commit rather than be ignored. The error identifies the target containing the committed content. When backup mode is enabled, retaining the old-content backup on this failure path is intentional recovery behavior; do not recommend deleting it merely because the commit rename succeeded.

File: src/services/file-safety/safeWriteText.ts:144-155
Timestamp: 2026-10-06T00:19:38.801Z
Learning: In the TypeScript Windows write path in `src/services/file-safety/safeWriteText.ts`, DACL preservation is intentionally best-effort. `_saveDaclWindows` failure must not prevent publication, because `icacls` can fail on non-NTFS mounts or in permission-restricted environments. `_restoreDaclWindows` failure is non-fatal after commit. Do not require fatal DACL handling or rollback of committed content under this contract.

File: src/core/tools/guardedWrite.ts:330-344
Timestamp: 2026-10-08T09:56:55.708Z
Learning: In Zoo-Code-Org/Zoo-Code, the TypeScript guardedWrite API in src/core/tools/guardedWrite.ts keeps core host-agnostic: extension-host callers supply other VS Code workspace folders through GuardedWriteOptions.additionalRoots. GuardedWriteOptions.approvedOutsideWorkspace represents a post-approval authorization, not path classification. ApplyDiffTool in src/core/tools/ApplyDiffTool.ts has no outside-workspace approval flow, so it must not receive that authorization merely because its target is outside the workspace.

123-151: Theicaclscalls still have no timeout.The earlier thread on
src/utils/safeWriteJson.tsasked for this, and it is still open. The author's reply coveredRollbackFailureError, not the timeouts. At head,_saveDaclWindowsand_restoreDaclWindowsstill callrunner("icacls", ..., { windowsHide: true }, ...)with notimeout. On Windows,safeWriteJsonwaits for these calls while it holds the advisory lock, so a stalled child process blocks every writer of that file.Add a finite
timeoutto both calls. Both helpers already returnfalsewhenicaclsfails, so a timeout keeps the best-effort DACL contract.

mockResolvedValue("referent.json")still answers everyreadlinkcall. The walk inresolveLockKeytherefore runs 8 times and returns at the depth bound. That is the same path as the two-link-cycle test. The comment "Only the link path is read" is still false.To fix it, return the referent once, then reject the way a non-link
readlinkdoes. Then asserttoHaveBeenCalledTimes(2).src/utils/safeWriteJson.ts (1)

…rather than by a flag Port of fc1c87f (landed on the U6 branch) to this unit. This unit carries the flag shape: the pass that resets recorded `teardownPassResets` and a caller that had only waited for the pass decided with `!ownedTeardown && !this.teardownPassResets`. A flag set by whichever pass happened to run first does not serialize the finalization: two cancellations that both waited on a pass which never resets - a save's post-publish cleanup, or a rejected save's discard cleanup - each saw the flag clear and each ran reset(). Measured before the change here: reset called twice for one session. - `teardownPassResets` is gone. `finalizeSession` claims the finalization: the first caller runs it, a caller arriving while it runs joins that attempt, a caller arriving afterwards does nothing. The revertChanges finalize and waiting callers both go through it. - The claim is per session and `open()` clears it, so a reused provider is finalizable again. - `reset()` also records the claim. Stated honestly that assignment is an invariant guard, not a reachable branch: reset clears relPath and activeDiffEditor, and every path that could reach finalizeSession returns early when either is missing, so no test reaches it. It is kept so that "a reset means the session is closed" holds at the reset itself. Tests ported with the fix. Red first with the tests ported and the production change absent: 2 failed | 146 passed. Green: 148 passed. Negative controls: claim removed entirely -> 5 failed (the two new cases plus three pre-existing teardown/finalization tests); in-flight dedup without the completed-claim check -> 2 failed, one more than on the U6/U8 branches because this unit's "revertChanges() holds the teardown through its finalization steps" test also depends on the completed claim; the guard inside reset() removed -> suite stays green at 148, reported with the reachability argument rather than labelled equivalent. Production file restored byte-exactly after the mutants (34a65032ec9f) and re-run at 148 passed. `tsc --noEmit` stays at this unit's 50-error baseline with no error in either touched file; eslint `--max-warnings=0` clean on both files; `src/eslint-suppressions.json` untouched.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick winRoute the diff-view move through the guarded write. Right now it overwrites an existing destination without any check.
When
preventFocusDisruptionis on, a move publishes the destination throughsaveDirectly(..., "create", ...).guardedWritethen rejects an existing destination the model never observed. It also re-checks containment under the lock.When
preventFocusDisruptionis off, Lines 537-539 run plainfs.mkdirandfs.writeFile(moveAbsolutePath, newContent, "utf8"). This path checks no observation and no version. It does not re-check containment against canonical paths, and it takes no per-path lock. A patch with*** Move to: <existing file>therefore replaces that file in diff-view mode. In focus mode, the same patch is rejected with the read-first remediation.This bypass is triggered by the PR's own scope: the PR says
apply_patchroutes all writes through the guard. It is the same mode-dependent enforcement gap that the earlier review fixed for the in-place save paths.Publish the destination through the guard in both modes. Apply the same completeness carry-over and rejection logic as the focus branch. Move that block out of the
if.Proposed fix
- } else { - // Write to new path and delete old file - const parentDir = path.dirname(moveAbsolutePath) - await fs.mkdir(parentDir, { recursive: true }) - await fs.writeFile(moveAbsolutePath, newContent, "utf8") - } + } else { + // The destination is a full-file publish in this mode too: guard it the + // same way, so an existing unread destination is not overwritten. + await task.diffViewProvider.saveDirectly( + change.movePath, + newContent, + false, + diagnosticsEnabled, + writeDelayMs, + "create", + sourceComplete, + false, + undefined, + ) + }Hoist
sourceCompleteand the destination-observation block above theif (isPreventFocusDisruptionEnabled)so both branches use them.As per path instructions: "Check approval and allowlist bypasses ... and enforcement at execution time—not only at presentation or planning time."

Timestamp: 2026-10-06T00:19:25.595Z
Learning: In src/services/file-safety/safeWriteText.ts, the TypeScript safeWriteText API intentionally requires confirmed directory-entry durability for a successful POSIX return. Directory-open or directory-fsync failures, including EINVAL, ENOTSUP, EISDIR, and EPERM, must produce PostCommitDurabilityError after the commit rather than be ignored. The error identifies the target containing the committed content. When backup mode is enabled, retaining the old-content backup on this failure path is intentional recovery behavior; do not recommend deleting it merely because the commit rename succeeded.

Timestamp: 2026-10-06T00:19:38.801Z
Learning: In the TypeScript Windows write path in `src/services/file-safety/safeWriteText.ts`, DACL preservation is intentionally best-effort. `_saveDaclWindows` failure must not prevent publication, because `icacls` can fail on non-NTFS mounts or in permission-restricted environments. `_restoreDaclWindows` failure is non-fatal after commit. Do not require fatal DACL handling or rollback of committed content under this contract.

Timestamp: 2026-10-08T09:38:50.043Z
Learning: In Zoo-Code-Org/Zoo-Code, Task.cwd identifies one workspace root, while write tools use isPathOutsideWorkspace(absolutePath) to classify paths against all VS Code workspace folders. A target in another workspace folder can therefore be outside Task.cwd while isPathOutsideWorkspace returns false. Write authorization must distinguish this case from an explicitly approved path outside all workspace folders.

126-129: 🩺 Stability & AvailabilityThe
icaclscalls still have no timeout, and a stalled child blocks writers holding the file lock.Both
execFile("icacls", ...)calls pass only{ windowsHide: true }.safeWriteJsonawaitssafeWriteTextwhile it holds the advisory lock onlockKey. If eithericaclschild stalls, this write hangs, and so does every other writer of the same file. DACL preservation is best-effort, so a timeout keeps the current contract. A timed-out save returnsfalseand emits a warning. A timed-out restore follows the existing non-fatal warning path. The earlier thread on this topic got a reply aboutRollbackFailureError, which is a different change. The timeout itself was never added.Proposed fix

A bounded timeout stays within that contract.

1213-1226: 🎯 Functional CorrectnessThe dangling-link test still runs the cycle-bound path, not the single-hop exit.
mockResolvedValue("referent.json")returns a link target on everyreadlinkcall.realpathrejects on every path, so eachcanonicalDirKeyfalls back to the literal key. The walk then loops 8 times and exits at the depth bound. This is the same path as the two-link-cycle test. The comment "Only the link path is read" is false. If the normaltarget === undefinedexit inresolveLockKeybroke, this test would still pass. Return the referent once, reject on later calls, and assertreadlinkwas called twice.Source: Path instructions

Two artifacts of merging org main a101c61, both of the kind that only exist in the merged tree: 1. src/core/tools/__tests__/readFileTool.spec.ts carried the same import twice - "import type { Task } from \"../../task/Task\"" at line 21 and again at line 26, one from each side of the merge. oxc reports it as [PARSE_ERROR] Identifier 'Task' has already been declared, which kills the whole file before a single test runs: vitest then says "Tests no tests" and CI's unit-test job is red with no failing test to point at. The second occurrence is removed; the first, in the type-import block, is the one the file's own ordering keeps. 2. This branch carries the hasClippedLines field (5 uses in src/integrations/misc/indentation-reader.ts) and main added src/integrations/misc/__tests__/indentation-reader-unicode.spec.ts, which pins the whole reader result with toEqual - a second-class merge conflict git cannot see. The spec's expectations learn the field, matching production: true for the two clipped-line cases, false for empty input and for both reader-error results. The spec's intent is untouched. Contract change to an existing test, stated explicitly: it pinned the pre-merge shape. numstat 6/0. The negative control was measured on the U6 branch (forcing the production flag to false turns exactly the two clipped-line tests red). src/eslint-suppressions.json is re-pruned after the merge, as both sides' violation counts move: the only real change is core/tools/__tests__/readFileTool.spec.ts @typescript-eslint/no-explicit-any 96 -> 94 (a decrease); the rest of the 1731/1731 numstat is the file's own re-serialization, verified by comparing the parsed files leaf by leaf - one changed leaf, zero increases. eslint . --ext=ts --max-warnings=0 is exit 0 on the merged tree after this (it exits 2 with the stale counts).

readWithIndentationomitshasClippedLines. Indentation reads can hide clipped lines.
formatWithLineNumbersclips lines longer thanMAX_LINE_LENGTHon these paths too. The single-line branch (Lines 342-348) and the main return (Lines 424-430) do not sethasClippedLines. A consumer then readsundefinedas "not clipped". Indentation reads are already partial inReadFileTool, so the observation stays incomplete. The clipping notice, however, depends on this flag.

…hat they claim
Four open threads on this PR, all of them about a test that passed without isolating the thing it names, plus the one production change among them.
1. safeWriteText.spec - the dangling-link key test ran the cycle path. mockResolvedValue("referent.json") answered EVERY readlink, including the call on the already-resolved key, so the walk never reached its normal exit; it looped to the depth limit and returned through the same door the cycle test below asserts. The mock now answers the link path only and rejects with EINVAL for the referent, the way a real readlink fails on a plain file. The readlink argument is compared on separators rather than through path.join, because the caller's spelling is "/tmp/linkdir/file.json" while path.join renders it with backslashes on Windows - a mock that never recognises the link would answer every call as "not a link", which is a third scenario, not this one. New assertion: readlink is called twice, once by resolvePublishTarget on the link and once by the fallback walk on the referent, and that count is what distinguishes the normal exit from the eight-call depth-limit exit. Negative control: restoring the blanket mock turns this test red with "called 2 times, but got 8 times"; the mutant was restored byte-exact.
2. applyDiffTool.guardedWrite.spec - "records no observation when the post-read stat fails" failed both stats. stat.mockRejectedValue rejects every call, so the pre-read stat failed too, and the observation was missing for the wrong reason: a regression that observes the file whenever the pre-read stat succeeds and ignores the post-read result passed this test. The first stat now resolves with the harness identity and only the second rejects. Negative control run both ways against the mutant "if (preReadStats)" plus versionTokenOfStat(postReadStats ?? preReadStats) in ApplyDiffTool: with the new mock the test is red (an observation is recorded), with the old blanket mock the same mutant is green - the reviewer's point, demonstrated rather than asserted. Both files restored byte-exact afterwards.
3. ApplyPatchTool - the move path's destination identity capture is dead here exactly as it was on the apply_diff unit: lines 459-474 return early whenever isMoveOutsideWorkspace, so isPathOutsideWorkspace(moveAbsolutePath) at the publish is always false and moveCanonicalTarget always undefined. Checked as dead rather than as a missed wiring, because the early return is the deliberate policy that a move outside every workspace root is refused with a tool error. It was not harmless: canonicalizeForApproval can throw, so a destination whose name could not be resolved raised an exception where the user should get that tool error. The capture is gone and the publish passes false and undefined with the guarantee in a comment. Same limitation as the unit this was ported from, recorded rather than hidden: no test in this repo drives an outside-workspace move, so this failure path is verified by reading the control flow, and the placeholder row on the plan of record (the three acceptance criteria: refused with a tool error, inside-workspace moves still publish, a canonicalizeForApproval rejection never reaches the caller) carries the test.
4. safeWriteJson.test - the CWE-732 mode-preservation comment sat above the confinement test and said "POSIX-only assertion" above a test that runs on every platform. It moved to the test it describes, the 0o600 mode-preservation case, which is the one wrapped in test.skipIf(win32) - so the note is now true of the test it annotates.
Measured: 120 passed, 4 skipped across safeWriteText.spec, applyDiffTool.guardedWrite.spec, applyPatchTool.execute.spec and safeWriteJson.test. tsc --noEmit with a local paths override: 0 errors. eslint . --ext=ts --max-warnings=0 exit 0. eslint-suppressions.json untouched.
…wants it The compile job's Check formatting step fails on this file. Verified on the commit CI actually checks - refs/pull/1918/merge, 761e449 (parents b7ab5a8 from main and 96b068b from this branch) - where the file is byte-identical to the copy on this branch, so formatting it here clears the merge ref too. The file is inside this PR's own diff, since this unit lowers suppression counts. Formatting only: parsed before and after and compared every key with JSON.stringify - 346 keys on both sides, zero keys differing, no suppression count moved. The byte change is indentation.
The compile job's Check formatting step runs 'prettier --check .' and lists 15 files on this PR (job 114122103447). The list is read from the job log with the ANSI codes stripped - the escape sequence sits between the bracket and the word, so a search for '[warn]' finds nothing and the reader is left with the summary line instead of the files. Every one of the 15 is inside this PR's own diff. Formatting only, verified as such: prettier --check passes on all 15; tsc --noEmit with the local paths override reports 0 errors; eslint . --ext=ts --max-warnings=0 exits 0; eslint-suppressions.json untouched. Five tests fail in this worktree (DiffViewProvider saveChanges default write delay x2, ClineProvider blanket auto-deny x3). Classified, not waved at: the same two spec files were run with the formatting stashed and unstashed and the failure sets are identical by name and by count (5 failed / 347 passed both ways), and the unit-test jobs are green at this head on CI - so they are local artifacts (the write-delay pair is the known DEFAULT_WRITE_DELAY_MS junction difference), neither introduced nor hidden by this commit.

Closes: #1375 (part 7 of 9 - the remaining write tools publish through the same guard; see the tracking issue for the unit map and merge order U1 U2 U3 U4 U5 U8 U6 U7 U9). Split plan of record:.
Description (how)
guardedWrite()is the single publish entry point for the write tools: it resolves the target againsttask.cwd, checks containment lexically and then canonically (a symlink that lands outside the workspace is rejected), picks the guard from the task'sObservationRegistry(create-if-absent, recreate, compare-and-swap on the version token, or the unobserved-edit remediation), and runs the publish on the per-path FIFO chain so concurrent writes to one path are ordered.approvedOutsideWorkspace) plus the other folder roots (additionalRoots) to the guard, which re-checks containment against those roots before publishing.apply_diff,apply_patch,write_to_file,edit,edit_fileandsearch_replaceall save throughDiffViewProvider.saveDirectly()/guardedWrite()with an explicit write kind, so a targeted edit is never treated as a full-file replacement and an unearned write fails with the re-read remediation instead of overwriting.fs.statpair and observe the file only when both tokens match, so the publish is authorized by the exact bytes the tool computed its hunks from; a stat failure leaves the file unobserved and never fails the read.Pre-Submission Checklist
