…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.

…t its account name
The DACL verification I added in the previous push accepted an access-control entry whose principal ended with the current account name. That suffix rule is the same bug class as the substring check it replaced, one layer up: "OTHERDOMAIN\bob" ends with "\bob" and grants a different account than the local "bob" the narrowing granted, so a DACL that was not narrowed to this process could be reported as verified. The redundant `lower === \`${wanted}\``` term repeated the equality test beside it.
Fix: build the set of principal names icacls can report for the granted account - the bare account name, plus the same name qualified with COMPUTERNAME (a local account's authority) and USERDOMAIN (a domain account's) - and require full-string equality, case-insensitively because Windows account names are. No prefix or suffix matching: a principal can contain spaces and can carry an authority that is not this one. The environment values are read at call time, so a process whose environment changed is not compared against a stale name.
This is a defect I introduced in this PR, fixed here rather than deferred.
Two tests, one per direction:
- a read-back naming OTHERDOMAIN\<user> is not accepted, so the publish reports DaclRestoreError instead of calling the narrowing verified;
- a read-back naming TESTMACHINE\<user> in lower case is accepted, because that is what icacls really prints for a local account and rejecting it would fail every real narrowing.
Measured: 77 passed in the safeWriteText spec. Negative controls, each restored byte-exactly (2ae3ffa69c): restoring the suffix rule turns exactly the other-domain test red; dropping the qualified forms turns exactly the machine-name test red. tsc --noEmit with a local paths override: 0 errors. eslint . --ext=ts --max-warnings=0 exit 0, no suppression-count change.
Port list: _expectedAcePrincipals and the exact-match rule belong to every unit that carries _aclEntriesAreNarrowedTo - U1 (Zoo-Code-Org#1910), U6 (Zoo-Code-Org#1915), U7 (Zoo-Code-Org#1917) and U9 (Zoo-Code-Org#1918) - and U1's version must keep its own staging-location rule when the surrounding tests are ported.

Re: Persistence Integrity check (Error) - "Use an atomic publish primitive; for an existing target, either compare the expected version as part of the commit or require every writer, including autosave, to use the same primitive."

…behind it A guard that protects only an internal path is not a guard: it aims at one object while the operation runs on another. This is the same defect class as the lock key in Zoo-Code-Org#1408 naming a different inode than the publish actually replaced - in both cases the check and the work were about different things, so the check could not stop the work. Here the guard sat in a private helper. finalizeSession() checked sessionFinalizationClaimed and awaited finalizationInFlight, and the two teardown paths called it as finalizeSession(() => this.reset()). But reset() is public, and it also set sessionFinalizationClaimed itself - a second place claiming the same thing. Task and every edit tool (Task.ts, ApplyDiffTool, ApplyPatchTool, EditFileTool, EditTool) call diffViewProvider.reset() directly, so a caller that arrived while a finalization was running bypassed the guard and ran a second teardown over a session that was already closing. Fix: the guard now sits on reset() itself - return if the finalization is claimed, join the attempt already running if one is in flight, otherwise run the teardown once and claim it after it completes. The teardown moved to a private performFinalReset() with no claim of its own, and finalizeSession() is gone: the two call sites just await this.reset(). One entry point, one claim, one teardown. The claim still lasts exactly one session: open() clears both fields when a new diff starts, so the many per-tool reset() calls across a provider's life stay finalizable. Test changes, all tightenings: - New test: two concurrent reset() calls on one session. Asserted on the teardown's own side effects (disposeActiveEditorListener, closeAllDiffViews) rather than on a flag, per the rule that a guard is proven by what it stops. - Five existing finalization tests stubbed the public reset() and counted the call. With the guard on the entry point, the entry may legitimately be called more often than the work runs, so they now stub the guarded teardown and still assert exactly one - which is what they meant to say. Measured: 152 passed. Two failures in this spec are pre-existing and unrelated (DEFAULT_WRITE_DELAY_MS pinned to 0 vs the branch's 1000): the same two fail at aa886ff with these changes stashed (2 failed | 151 passed there). Negative control: deleting only the in-flight join turns exactly two tests red - the new concurrency test and "revertChanges() finalizes the session once when two cancellations wait on the same pass" - and the mutant was restored byte-exactly (786b227b9c). tsc --noEmit with a local paths override: 0 errors. eslint . --ext=ts --max-warnings=0 exit 0, no suppression-count change. Port list: any unit carrying DiffViewProvider's finalization pair (sessionFinalizationClaimed / finalizationInFlight) needs this move - U6 (Zoo-Code-Org#1915) and U7 (Zoo-Code-Org#1917) are the candidates; check with git grep for finalizeSession before assuming the same shape.

…k on an unscoped publish The lock key, the object a guard checks, and the inode an operation actually replaces have to be the same object. This is the same defect class as the lock key in Zoo-Code-Org#1408 and the other direction of what b809020 fixed in U6: there the lock named the referent while the publish replaced the link, so the link-path lock was missing; here the lock already names the link, so what U8 lacks is the referent lock. The finding, quoted: "Do not replace the referent lock with only the link-path lock, because the existing contract serializes symlink aliases with direct referent writers while the link exists." An unscoped write replaces the link, so the link-path lock names the inode it replaces - that half was already right. A writer that opens the referent by name takes the referent lock, and while only the link-path lock is held the two writes overlap: after this commit resolveLockKey names the link rather than the referent, so a writer that queued behind the referent never meets the writer that replaced the link, and their merge reads overwrite each other. Fix: an unscoped write now holds both locks when the two identities differ. - Acquisition order is the sorted order of the two keys, so two writers approaching the pair from opposite sides cannot each hold one and wait for the other; release is the reverse, and every lock acquired is released even if an earlier release threw. - A failed acquisition releases what it already took before rethrowing: the protected block has not started, so its finally would not run, and a held lock outlives the call until the stale timeout. - A caller that declares confineTo still takes exactly one lock, the referent, because that is the identity it publishes through. - The two keys are compared the way the filesystem would (case-insensitively on win32): resolveLockKey canonicalizes, so byte-for-byte they can name one file twice, and locking a file this call already locked would stall on its own stale timeout. - publishOverLink is computed once and reused for the publish target and the publish call, instead of the same condition being written twice. Cost accepted: a default write now resolves the referent, one more realpath. That is a read of the link target for locking purposes, not a decision to publish through it - the publish target is unchanged, which the new test asserts. Test changes: - New: serializes a writer that names the referent directly while the link still exists - both keys acquired in sorted order, both released in reverse, the DACL capture still issued for the file this write replaces, and the bytes landing on the link while the referent keeps its own content. - Re-pointed: locks the link path and the referent when the caller declared no confinement scope - it previously asserted the link path alone, which is the half the finding says is not enough. - Control: the confined writer test now asserts exactly one lock, which is what stops the second lock from being added unconditionally. - Test-only seam: the two safeWriteJson specs stub child_process.execFile, the one boundary icacls is reached through. On a sandboxed host a real icacls cannot run, so every write failed the restore check and rolled back: 13 of 40 tests in these files were red at 88d654a locally while CI was green on both runners, which made the lock behaviour impossible to observe here at all. The DACL semantics are unchanged and stay asserted in safeWriteText.spec.ts, where the runner is the subject under test; the new test additionally asserts the capture was issued with the path this write replaces, so stubbing cannot quietly skip it. Measured: 37 passed, 4 skipped across the two specs (13 of them were unobservable before the stub). Red first: the two tests above were red before this change. Negative control - reducing the key list to the link path alone, U8's pre-fix shape - turns exactly those two red and leaves the confineTo control green; the mutant was restored byte-exactly (3f21aac6e2). tsc --noEmit with a local paths override: 0 errors. eslint . --ext=ts --max-warnings=0 exit 0, no suppression-count change. Port note for the rest of the chain: the fix is not byte-identical across units, because the units differ. U6 (b809020) lacked the link-path lock and U8 lacked the referent lock; a later unit carrying either shape needs its own condition read first, not this diff copied.

🧠 Learnings (1)
📓 Common learnings
Learnt from: easonLiangWorldedtech
Repo: Zoo-Code-Org/Zoo-Code PR: 1916
File: src/integrations/editor/DiffViewProvider.ts:145-160
Timestamp: 2026-10-07T06:26:17.803Z
Learning: In src/integrations/editor/DiffViewProvider.ts, DiffViewProvider.open() intentionally records a stat-matched preview observation with complete=false only when the task has no existing observation for the path. Existing model-read observations must remain unchanged so accepted saves detect changes since the model read. Preview observations are not complete model reads; review preview version tracking separately from edit authorization.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win
Do not adopt a match when the rejection was about completeness.
canAdoptPublishedContent() checks only that the versions pair up (preOpenObservation.version === openToken). It does not check the write kind or the observation's completeness. Here is how that fails:
- The model reads a file partially, so its observation has
complete=false. WriteToFileToolcallssaveChanges(..., "update").open()keeps the model's observation. The bracketing stats match, soopenTokenequals that version.- Autosave writes the full replacement to disk.
guardedWritethrowsGuardRejectedError("File was only partially read ...")before any CAS runs.- The adoption gate passes: the versions match, the buffer is clean, and the bytes match.
saveChangesreturns a normal success.
The tool reports a successful full-file replacement for a write the completeness gate rejected. The lines the model never read are gone, and nothing tells the model. Adoption is only valid when the token moved and nothing else failed. For "create" and "update", that also requires a complete prior observation.
Proposed fix
- private canAdoptPublishedContent(): boolean {
+ private canAdoptPublishedContent(writeKind: GuardedWriteKind): boolean {
...
if (this.preOpenObservation === null) {
return false
}
+ // A full-file publish was rejected for a partial read, not a moved token.

The compile job's Check formatting step runs 'prettier --check .' and lists 10 files here (job 114112508335). The list is taken from the job log with the ANSI codes stripped first - the escape sequence sits between the bracket and the word, so a search for '[warn]' matches nothing - and the parsed count is checked against the log's own 'Code style issues found in 10 files' line rather than trusted. All ten are inside this PR's own diff; eslint-suppressions.json is not among them, so no suppression count is involved. Formatting only, verified as such: prettier --check passes on all ten; tsc --noEmit with the local paths override reports 0 errors; eslint . --ext=ts --max-warnings=0 exits 0; eslint-suppressions.json untouched. Three tests fail in this worktree: DiffViewProvider saveChanges default write delay x2 (the known DEFAULT_WRITE_DELAY_MS junction difference) and the integration test that publishes through a real rename with no mocking (real icacls cannot run under this sandbox, so the DACL path fails locally while CI is green). Classified rather than waved at: the same two spec files were run with the formatting stashed and unstashed and the failure set is identical by name and by count, so this commit neither introduced nor hid any of them.
platform-unit-test (ubuntu-latest) failed at this head: test:coverage:misc reported 'expected "vi.fn()" to be called with arguments: [ icacls, ArrayContaining{...} ]' (1 failed / 107 passed / 2 skipped), and windows was cancelled alongside it. The failing assertion is the one this PR added in the referent-writer test: it required the DACL capture to have been issued for the replaced path.
The capture is genuinely windows-only in production: safeWriteText gates the DACL dump on platform === "win32" (line 626), because icacls is a win32 tool. So the assertion was asking a linux runner for a windows command - the test's applicability did not share a source with the condition that runs the command. The DACL semantics themselves stay asserted in safeWriteText.spec.ts, where the runner is the subject and the platform is passed explicitly; the integration spec that shells out to a real icacls is already gated with skipIf(process.platform !== "win32"). This was the one ungated case.
The assertion now follows the same condition production uses: on win32 it requires the capture against the replaced path, and on another platform it asserts the opposite - that no DACL command was issued at all. Both directions are load-bearing: flipping the condition to !== makes the test red on either runner (verified on this win32 host: 7 passed with the condition, 1 failed with it flipped, mutant restored byte-exact).
Verification: the three safeWriteJson/file-safety specs pass locally; prettier --write then --check with the repo config reports the file clean; tsc --noEmit with the local paths override reports 0 errors; eslint . --ext=ts --max-warnings=0 exits 0; eslint-suppressions.json unchanged.
…strings compare Port of Zoo-Code-Org#1915's 5131bc0 to this unit's shape. platform-unit-test (windows-latest) failed here with four safeWriteJson.test.ts assertions reporting 'expected [Function] to throw error including Primary rename failed but got Lock file is already being held', and the two directory-creation names are the diagnosis: when a component of the target is missing, the previous fold could not reach a canonical form. This unit compared the two lock identities by case alone. On Windows the filesystem folds two spellings of one directory entry in two ways - case anywhere, and short (8.3) names inside a component - and a CI agent hands out its runner profile directory as RUNNER~1, so os.tmpdir() below it is spelled two ways at once. resolveLockKey canonicalises through the highest ancestor it can reach, so a case-only comparison leaves the canonical referent key unequal to the requested short spelling: one .lock directory is asked for twice and the second acquisition collides with the first one's own lock. _lockIdentityKey now canonicalises the deepest EXISTING ancestor and appends the segments below it, case-folded on Windows. The walk starts at the PARENT, not at the file: the lock is the entry <path>.lock beside the file, so the final component must never be resolved through a symlink, or a link and its referent would fold into one key and the two distinct .lock entries this call takes on purpose would collapse into one. That boundary was established on the unit this is ported from, where starting the walk at the file turned three existing tests red; the port is not byte-identical because this unit computed sameIdentity inline. Verification and its limit, stated plainly: the four CI failures do not reproduce on this host, because the local os.tmpdir() has no short-name ancestor - only a CI agent (or a host where 8.3 names are in play) exercises that spelling, so the four are verified by CI, not locally. What is verified locally is that the fold does not disturb anything else: the safeWriteJson specs pass 37 / 4 skipped, and safeWriteText.integration.spec.ts fails the same single test with and without this change (identical by name, checked by stashing the change and re-running), which is the known environment limit - that test runs the real icacls, which cannot run in this sandbox. prettier --write then --check with the repo config clean; tsc --noEmit with the local paths override 0 errors; eslint . --ext=ts --max-warnings=0 exits 0; eslint-suppressions.json unchanged. Still owed by this port, recorded rather than assumed: the mixed-ancestor acceptance test (existing ancestor spelled short with a missing tail) has not been ported yet, because in this unit sameIdentity is only consulted when publishing over a link, so the test must be re-derived against that shape rather than copied.

…link path
proper-lockfile writes ${key}.lock, so the spelling of a lock key is part of its identity.
The referent key came from resolveLockKey, which canonicalizes the parent directory, while
the link-path key was the plain path.resolve result. Under a parent that resolves elsewhere
- macOS /var to /private/var under os.tmpdir(), a workspace opened through a symlinked
folder, a symlinked home - the two spellings named one file, and a writer that named the
canonical path took a lock file in a different directory. One identity, two locks, and the
lost update the lock exists to prevent.
resolveLinkPathLockKey canonicalizes the parent and keeps the final component unresolved:
a link and its referent must keep two distinct keys, which is what lets an unscoped write
lock both. Its failure behaviour is canonicalDirKey's, which is also what resolveLockKey
already exposes one line earlier in this function - a realpath error that is not ENOENT
propagates, and a path whose every ancestor up to the root is missing keeps its literal
spelling. The look-alike _resolveScopeRoot was not merged in: it canonicalizes a directory
by resolving the path itself, and returns the lexical path at the root, so it would follow
the final component this key must not follow.
Regression test: a regular file whose parent resolves through a symlink takes exactly one
lock, and that lock names the canonical file. Negative control measured in this harness:
linkPathLockKey back to the plain path.resolve result -> 1 failed (that test), 38 passed.
Also in this commit, review thread 4236123803: a test restored COMPUTERNAME by assignment,
which on a host without it writes the literal "undefined" and leaks an invented authority
into every later DACL case. It now deletes the variable when it was unset, the way USERDOMAIN
already did, and a canary case asserts the rule. Negative control: restoring by assignment
again, with COMPUTERNAME absent from the host environment -> 1 failed (the canary), 77 passed.
Baselines after the sweep: safeWriteText spec 78 passed; safeWriteJson lock-key and behaviour
specs 38 passed / 4 skipped; tsc at this branch's post-merge baseline of 74 error lines with 0
in the touched files; eslint --max-warnings=0 clean on all four files;
src/eslint-suppressions.json untouched. One integration case
(publishes the new bytes and leaves no staging or backup residue) fails identically before and
after this commit: it shells out to a real icacls, which cannot verify a restore in this
sandbox. Verified by stashing the change and re-running it at the parent commit.
The compile job failed at Check formatting on this head, and the whole warn] list in the job log names exactly one file: src/utils/__tests__/safeWriteJson.lockKey.spec.ts, followed by the log's own 'Code style issues found in the above file'. The formatting gate is the whole list from the log, not an excerpt, so nothing else in this PR's diff needed touching. Formatting only: one mockedLstat.mockImplementation call exceeded printWidth 120 and is wrapped onto its own argument list. No assertion, mock behaviour, or identifier changed; the diff is 3 insertions and 2 deletions in that one file. Done with the repo's own prettier rather than by hand: prettier --write followed by prettier --check with the repo config (printWidth 120, endOfLine lf) reports the file clean. Verified the same way the CI step runs it, from inside the repo, so the local signal matches the gate instead of a default-config run outside it. Verification: the two safeWriteJson specs pass 38 / 4 skipped after the reflow; tsc --noEmit with the local paths override 0 errors; eslint . --ext=ts --max-warnings=0 exits 0; eslint-suppressions.json unchanged.

Timestamp: 2026-10-10T06:09:48.462Z
Learning: In src/utils/safeWriteJson.ts, link-path advisory lock keys must canonicalize parent directories without following the final component. Reuse resolveLinkPathLockKey from src/services/file-safety/safeWriteText.ts. Do not substitute _resolveScopeRoot, which resolves the directory path itself. An unscoped write that replaces a symlink must preserve distinct lock keys for the symlink entry and its referent.

File: src/integrations/editor/DiffViewProvider.ts:145-160
Timestamp: 2026-10-07T06:26:17.803Z
Learning: In src/integrations/editor/DiffViewProvider.ts, DiffViewProvider.open() intentionally records a stat-matched preview observation with complete=false only when the task has no existing observation for the path. Existing model-read observations must remain unchanged so accepted saves detect changes since the model read. Preview observations are not complete model reads; review preview version tracking separately from edit authorization.

Update the onWarning doc to match the DaclCaptureError contract.
The doc says that when a DACL "could not be captured", "the write still proceeds (a missing or failing icacls must not block saving)". Step 2 now throws DaclCaptureError before the commit for an existing target (Lines 655-671). A caller who reads this option doc will expect a warning, but the write fails. Change the doc to say:
- A capture failure on an existing target rejects the write.
onWarningreceives the access-check warning (Line 676) and the post-commit restore/narrowing notices.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Windows saves fail when the file path contains a space, and the (I) check never matches.
According to the Line 804-807 comment, icacls /restore normally fails on Windows. So on Windows, the _restrictDaclWindows read-back decides whether almost every write is kept. _aclEntriesAreNarrowedTo has two defects:
- A path with a space is rejected.
- The regex
[^:()]+takes everything after the drive colon as the principal of the first entry. - Example: for
C:\Users\bob\My Projects\cfg.json DESKTOP\bob:(F), the principal starts as\Users\bob\My Projects\cfg.json DESKTOP\bob. - Lines 259-262 drop only the first whitespace-separated token. That leaves
Projects\cfg.json DESKTOP\bob. - This string is not in
expectedPrincipals, so the check returnsfalse. - The write then fails with
DaclRestoreError, and the code rolls the content back. - Result: on Windows, every
safeWriteText/safeWriteJsonpublish fails in a workspace whose path contains a space (for exampleOneDrive - CompanyorMy Projects). - The integration test runs under
os.tmpdir(), which has no spaces, so it does not catch this.
- The regex
- The
(I)check is dead code.match[2]is the text inside a single pair of parentheses, so forbob:(I)(F)it isI.flags.includes("(I)")can never be true.- An inherited ACE for the current user is therefore accepted as "verified".
- The test at
safeWriteText.spec.tsLines 865-885 rejects only becauseDESKTOP\usersis a different principal. It does not reach the inheritance check.
_restrictDaclWindows already knows filePath. Strip that known prefix, then parse each line in full.

Update _aclEntriesAreNarrowedTo and its call from _restrictDaclWindows to strip
the known filePath before parsing each ACL entry, so paths containing spaces do
not contaminate the principal. Parse complete entry flags so an inherited (I)
ACE is rejected, including when followed by other flags; preserve the existing
expected-principal validation.

Split unit U8 of the file-safety series. Base is U8's parent per the declared merge order.
Scope (one gate scope): the interactive save path -
saveChanges()publishes through the guard, a rejected save cleans up only its own placeholder and tab, and one teardown path owns a cancelled save.Content source of record:
kind: commit, base7c291bb08-> head6768ccfaf, replayed onto the current main tip so this branch carries nothing that main already has.Budget (own delta, not the stacked view): 2542 a+d / 486 changed executable lines. The 2542 a+d is above the 1000 hard cap - documented deviation: the file's 2056-line spec is a single file whose tests are interleaved across the behaviours, and splitting it would move tests away from the behaviour they prove.
The GitHub view also carries the unmerged base, so the numbers above are this unit's own delta.

Closes: #1375 (part 8 of 9 - the interactive save path publishes 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)
DiffViewProvider.saveChanges()publishes throughguardedWrite()instead of writing through the VS Code file service, so an interactive save is authorized by the version the diff was built on and a stale or unearned save fails with the re-read remediation.runTeardown()tracks the pass that started it, so a cancellation arriving during a save cannot run the same cleanup twice over the same buffers and tabs.Pre-Submission Checklist

No user-facing documentation change: the guard is internal behaviour of the save path, and the model-facing remediation text (re-read the file, then retry) already existed in the earlier units of this series. No new setting, no schema change, no webview surface, so the persisted-setting round-trip checklist does not apply. No
.changesetand no CHANGELOG edit (AGENTS.md).Additional Notes
