Merge Risk: 🟡 Moderate · up to Resolve the JSON publish-target race and assess the Windows and shared-file permission regressions before merging. The affected tests also need independent setup to reliably protect these paths. Caution Pre-merge checks failedPlease resolve all errors before merging. Addressing warnings is optional.
❌ Failed checks (1 error)

Full details: Security BoundariesExplanation The new publish path can write to a different path than the one that received approval. Resolution Resolve the publish target before any allowlist, workspace-confinement, protected-file, or approval decision. Validate the canonical target and its parent against the same policy, and display that canonical target for approval. Reject targets outside the approved root unless the caller explicitly approves that target. Apply the same rule in

In `@src/integrations/editor/DiffViewProvider.ts`:
- Line 1160: Update the write flow around safeWriteText so an existing
symbolic-link absolutePath is preserved and its referent receives the content
instead of replacing the link; retain current behavior for regular files. Add a
regression test covering both the symbolic-link type and the referent’s updated
content.
In `@src/services/file-safety/__tests__/safeWriteText.spec.ts`:
- Around line 134-138: Remove the duplicate safeWriteText mock in
DiffViewProvider.spec.ts, keeping only the existing
../../../services/file-safety/safeWriteText mock because it resolves to the
valid module path. Do not change the safeWriteText behavior or unrelated tests.
In `@src/services/file-safety/safeWriteText.ts`:
- Around line 118-128: Update the descriptor handling in the safeWriteText flow
around _fsyncFile so both the newly written and pre-written temp-path branches
close their file descriptors in finally blocks. Ensure writeSync and _fsyncFile
errors still propagate while closeSync runs on every path, including failures.
- Around line 68-82: Update _copyDaclWindows and both callers in
src/services/file-safety/safeWriteText.ts lines 68-82 and 131-153, plus
src/utils/safeWriteJson.ts lines 118-141, to preserve an accessible target ACL
source before moving the target, restore via a valid directory rather than the
staging file, and remove the ACL dump in a finally block even when restoration
fails. Add platform-override tests covering icacls arguments and fallback
behavior at all affected flows.

0o644, and fall back to a suitable default only when the target does not exist.

- Line 479: Update the openSync assertion in the safeWriteText test to use a
path-agnostic matcher for the parent-directory path instead of hardcoding
“/tmp/test-dir”, while preserving the expected “r” mode argument.
In `@src/services/file-safety/safeWriteText.ts`:
- Around line 140-141: Update safeWriteText so _stagingDir(dirPath) is only
called when options?.tempPath is absent; when a caller supplies tempPath, use it
directly without creating the staging directory. Preserve the generated
staging-directory and _tempName path behavior for calls without tempPath.
In `@src/utils/safeWriteJson.ts`:
- Around line 109-128: Update safeWriteJson and its
_streamDataToFile/safeWriteText flow so the staged temporary file is created
beside the resolved targetPath rather than absoluteFilePath, avoiding
cross-filesystem rename failures when the target is a symlink. Preserve the
existing backup, commit, and rollback behavior.

URL: https://github.com/Zoo-Code-Org/Zoo-Code/pull/1395
Timestamp: 2026-10-08T22:57:26.617Z
Learning: For Zoo-Code-Org/Zoo-Code PR #1395, src/utils/safeWriteJson.ts intentionally supports leaf-symlink targets by resolving and publishing at the referent. Locking, merge reads, staging, and publication use the canonical path to preserve the alias and coordinate alias/referent writers. Do not require blanket rejection of leaf symlinks. The user assigns storage-root confinement to confineTo in file-safety units U4/U6, tracked separately in easonLiangWorldedtech/Zoo-Code#41. The cited _refuseSymlinkedAncestors guard at commit 17c736ecb is an opt-in refuseSymlinkTarget policy and is not present at PR #1395 head 6df83d845.
Learnt from: easonLiangWorldedtech
URL: https://github.com/Zoo-Code-Org/Zoo-Code/pull/1395
Timestamp: 2026-10-08T21:58:25.198Z
Learning: In src/services/file-safety/safeWriteText.ts, staging-directory rejection cleanup must not remove a pre-existing directory or a directory created by a concurrent safeWriteText operation. The user identifies concurrent writes as the reason to restrict cleanup to directories created by the current call. Initial lstatSync absence alone does not establish creation ownership.

URL: https://github.com/Zoo-Code-Org/Zoo-Code/pull/1395
Timestamp: 2026-10-08T20:32:56.969Z
Learning: For PR #1395 in Zoo-Code-Org/Zoo-Code, the author defines post-commit Windows DACL restore failure in src/services/file-safety/safeWriteText.ts as a warning rather than a generic write failure. The stated reason is to prevent callers from treating committed content as an uncommitted write and running editor-side rollback. A change to surface a post-commit error must include caller handling that distinguishes committed content from pre-commit failure. This contract does not imply that DACL preservation is confirmed.

URL: https://github.com/Zoo-Code-Org/Zoo-Code/pull/1395
Timestamp: 2026-10-08T16:32:43.821Z
Learning: For PR #1395 in Zoo-Code-Org/Zoo-Code, the author defines a cross-session cleanup queue or reaper for safeWriteText artifacts in src/services/file-safety/safeWriteText.ts as a separate persistence-series task tracked in easonLiangWorldedtech/Zoo-Code#41. It requires a cross-session store and a designated reaper owner. The current PR uses bounded cleanup retries and warnings that identify leftover paths; do not require an unrelated cross-session reaper implementation in this unit.

362-375: Rename the failed-publish test. Its title describes removed backup behavior.
safeWriteJsonno longer passesbackup, so this code path creates no backup copy. The test title says "because the backup is a copy". The comment on Line 369 says "The backup is a copy". Both statements are now incorrect. Line 363 also says "should be restored", but no restore step exists. Describe the real invariant: the rename is the only publish step, and the target is never moved before it.Proposed fix
- test("a failed publish leaves the target in place because the backup is a copy", async () => { + test("a failed publish leaves the original target intact", async () => { - const initialData = { message: "Initial content, should be restored" } + const initialData = { message: "Initial content, must survive" } ... - // The backup is a copy, so the only rename is the publish. + // The publish is the only rename.

170-170: 🚀 Performance & ScalabilityRemove
/Tfrom theicacls /savecall.Line 170 still passes
/T. When the name is a file path,/Talso matches files with the same name in every subdirectory. The save then walks the whole subtree, and the later/restoreapplies DACLs to every matching file. The earlier review raised this, and the current code still contains it. The test assertions at Lines 340 and 503 insrc/services/file-safety/__tests__/safeWriteText.spec.tsmust change together with this line.
400-458: 🩺 Stability & AvailabilityEarlier DACL findings are still present in this block.
- Every Windows write still runs one
/saveand two/restoreprocesses. On non-elevated hosts the restore is documented to always fail, and no module-level flag stops the repeat.- The capture still fails closed on every existing target. No check detects volumes without persistent ACLs, such as FAT32, exFAT or

536-538: 🎯 Functional CorrectnessFix the DACL-restore warning text.
The warning still says the content is "only recoverable from the backup copy" for every write. It does not check
backupCreated, and it never printsbackupPath. With the defaultbackup: false, the message points the user to a file that does not exist.src/services/file-safety/__tests__/safeWriteText.spec.ts (5)

1409-1467: 📐 Maintainability & Code QualityReset mocks in these top-level
describeblocks.These blocks still run without
vi.resetAllMocks(). Theirnot.toHaveBeenCalledandtoHaveBeenCalledWithassertions depend on call history and stubs left by earlier tests, for examplefs.copyFile.mockRejectedValueat Line 1460.
…f swallowing them Lifecycle: _releaseStagingDir caught every error from fs.rmdir and said nothing, so a staging directory left behind by a transient failure was invisible forever. ENOENT and ENOTEMPTY are benign and stay silent: the first means another writer already removed it, the second means a concurrent write is still staging here, which is the concurrency guard the directory exists for. Anything else (EBUSY, EPERM, EACCES, ...) is transient: retry once, then warn with the path and the errno. A leftover staging directory is acceptable, an invisible one is not. Negative controls, as measured - three separate mutations, each turning exactly one test red: swallow every rmdir error again -> 1 failed (the retry-and-surface test) make ENOTEMPTY non-benign -> 1 failed (the benign test) suppress the post-retry warning -> 1 failed (the retry-and-surface test) Production restored byte-identical after each. How this differs from the attempt I reverted earlier: that version asserted a loose substring that an unrelated warning in the flow already satisfied, so its controls stayed green. This version first proved with a probe that fs.rmdir really is called with the staging path during a successful write, then asserts the exact message this code emits. Local: safeWriteText.spec 74 passed / 1 skipped; src-level tsc --noEmit 0; eslint 0 err / 0 warn.

Timestamp: 2026-10-08T22:57:26.617Z
Learning: For Zoo-Code-Org/Zoo-Code PR #1395, src/utils/safeWriteJson.ts intentionally supports leaf-symlink targets by resolving and publishing at the referent. Locking, merge reads, staging, and publication use the canonical path to preserve the alias and coordinate alias/referent writers. Do not require blanket rejection of leaf symlinks. The user assigns storage-root confinement to confineTo in file-safety units U4/U6, tracked separately in easonLiangWorldedtech/Zoo-Code#41. The cited _refuseSymlinkedAncestors guard at commit 17c736ecb is an opt-in refuseSymlinkTarget policy and is not present at PR #1395 head 6df83d845.

Timestamp: 2026-10-08T12:37:36.839Z
Learning: In src/integrations/editor/DiffViewProvider.ts, DiffViewProvider.saveDirectly intentionally requires a writable parent directory because it uses safeWriteText for atomic rename-based publication. Do not request an in-place fs.writeFile fallback for a writable target in a non-writable directory; that fallback would discard the intended atomicity. The caller separately checks fs.access with fsConstants.W_OK to reject existing non-writable targets and permits ENOENT for new targets.

Timestamp: 2026-10-08T20:32:56.969Z
Learning: For PR #1395 in Zoo-Code-Org/Zoo-Code, the author defines post-commit Windows DACL restore failure in src/services/file-safety/safeWriteText.ts as a warning rather than a generic write failure. The stated reason is to prevent callers from treating committed content as an uncommitted write and running editor-side rollback. A change to surface a post-commit error must include caller handling that distinguishes committed content from pre-commit failure. This contract does not imply that DACL preservation is confirmed.

Assert the result for the missing-target path.
When fs.access returns ENOENT, this test checks the publish call but not the result of saveDirectly. Assert finalContent from the returned value so a stale result cannot pass this test. As per path instructions, “For tests that assert only mock call counts, confirm a corresponding return-value assertion exists.”

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
Keep the target's group when you publish over an existing file on POSIX.
The publish is a rename, so the target becomes a new inode. That inode gets the process's effective uid and primary gid, or the directory's gid when the directory is setgid. The old fs.writeFile path in DiffViewProvider.saveDirectly wrote in place and kept the target's owner and group.
Example: a shared-repository file is 0o664 with group devs, and the user's primary group is not devs. After one direct save, fchmodSync restores 0o664, but the group is now the user's primary group. Other devs members lose write access. The fchmodSync fix for mode narrowing exists to prevent this same regression, so the gid has to be preserved too.
Capture gid from the same statSync call and apply it on the descriptor as a best-effort step. fchownSync(fd, -1, gid) works when the process belongs to that group, which is the case that matters. The caller-staged branch at Lines 400-404 needs the same change.
Proposed fix
let targetMode = 0o644 // default for a fresh target
let targetExists = false
+ let targetGid: number | null = null
try {
- targetMode = fsSync.statSync(targetPath).mode & 0o777
+ const st = fsSync.statSync(targetPath)
+ targetMode = st.mode & 0o777
+ targetGid = typeof st.gid === "number" ? st.gid : null
targetExists = true
@@
try {
if (targetExists) {
+ if (targetGid !== null && process.platform !== "win32") {
+ try {
+ fsSync.fchownSync(fd, -1, targetGid)
+ } catch {
+ // best-effort: not a member of the target's group
+ }
+ }
fsSync.fchmodSync(fd, targetMode)
}Add a test with a gid on the statSync stub. It must assert fchownSync(fd, -1, gid) and that fchownSync runs before fchmodSync. That order matters because chown can clear setgid bits.

…ate probe errors _stagingDir re-checks the directory after mkdirSync to catch a symlink swap. If that lstatSync itself fails (EIO, or ENOENT if the directory is removed in between) the error propagated on its own, leaving a staging directory this call had just created: the caller never receives the path, so nothing else can remove it. Wrap the re-check, call _abandonIfCreated() - which only removes a directory this call created - and rethrow the original error unchanged. Regression test scripts the staging directory's own probes by path, not by call position: this flow also lstats ancestors for the symlink refusal, so a mockRejectedValueOnce chain is consumed by the wrong site. Negative control as measured: removing the _abandonIfCreated() call turns exactly one test red. Local: safeWriteText.spec 75 passed / 1 skipped; src-level tsc --noEmit 0; eslint 0 err / 0 warn.

Every other suite in this directory mocks fs/promises and fs, so nothing proves the real open/write/fsync/rename sequence produces bytes on disk. This suite uses a real temporary directory with no mocks and asserts the outcome for a new target and an existing target, plus the absence of staging, temp or backup residue. Negative control as measured: commenting out the publish rename (safeWriteText.ts:509) turns BOTH tests red. Honest limit: the residue assertion was not proven load-bearing by neutering the unlinks at :573 and :579 - those sites produce no residue in these scenarios, so those runs stayed green. The residue check is a guardrail, not a claim backed by its own control. Local: integration spec 2 passed; src-level tsc --noEmit 0; eslint 0 err / 0 warn.

Timestamp: 2026-10-08T22:57:26.617Z
Learning: For Zoo-Code-Org/Zoo-Code PR #1395, src/utils/safeWriteJson.ts intentionally supports leaf-symlink targets by resolving and publishing at the referent. Locking, merge reads, staging, and publication use the canonical path to preserve the alias and coordinate alias/referent writers. Do not require blanket rejection of leaf symlinks. The user assigns storage-root confinement to confineTo in file-safety units U4/U6, tracked separately in easonLiangWorldedtech/Zoo-Code#41. The cited _refuseSymlinkedAncestors guard at commit 17c736ecb is an opt-in refuseSymlinkTarget policy and is not present at PR #1395 head 6df83d845.

Timestamp: 2026-10-08T12:37:36.839Z
Learning: In src/integrations/editor/DiffViewProvider.ts, DiffViewProvider.saveDirectly intentionally requires a writable parent directory because it uses safeWriteText for atomic rename-based publication. Do not request an in-place fs.writeFile fallback for a writable target in a non-writable directory; that fallback would discard the intended atomicity. The caller separately checks fs.access with fsConstants.W_OK to reject existing non-writable targets and permits ENOENT for new targets.

RooIgnoreController.validateAccess is not modified by this PR; an independent concern in that controller requires separate validation rather than inclusion as a defect introduced by this PR.

Timestamp: 2026-10-08T20:32:56.969Z
Learning: For PR #1395 in Zoo-Code-Org/Zoo-Code, the author defines post-commit Windows DACL restore failure in src/services/file-safety/safeWriteText.ts as a warning rather than a generic write failure. The stated reason is to prevent callers from treating committed content as an uncommitted write and running editor-side rollback. A change to surface a post-commit error must include caller handling that distinguishes committed content from pre-commit failure. This contract does not imply that DACL preservation is confirmed.

Learning: For PR #1395 in Zoo-Code-Org/Zoo-Code, the author defines a cross-session cleanup queue or reaper for safeWriteText artifacts in src/services/file-safety/safeWriteText.ts as a separate persistence-series task tracked in easonLiangWorldedtech/Zoo-Code#41. It requires a cross-session store and a designated reaper owner. The current PR uses bounded cleanup retries and warnings that identify leftover paths; do not require an unrelated cross-session reaper implementation in this unit.

An earlier thread recorded the FAT32/exFAT concern as addressed. However, this branch still throws

Assert that the target is the only directory entry. The current filter misses the Windows DACL dump.
_leftovers checks only for .file-safety-staging, .new_, and .bak. On Windows, the existing-file case creates .safeWriteText.acl.tmp_<ts>_<rand>.tmp in dir, and this filter does not match that name. If the dump cleanup fails, the test still passes. The suite claims to check for "absence of residue", and the windows-latest CI run is the only place where this artifact appears.

Remove /T from the icacls /save call. The previous fix is not in the current code.
An earlier thread recorded this issue as addressed. However, Line 179 still passes /T, and the spec still asserts /T at Lines 340 and 499.
When /T is used with a file path, icacls does more than save one entry. It walks the target directory and every subdirectory, and it saves every file with the same name. For example, <root>\package.json also matches every package.json under node_modules. This has three effects:
- Every Windows
saveDirectlycall and everysafeWriteJsonwrite over an existing file pays for a recursive tree walk. - Step 5 runs
/restoreonpath.dirname(targetPath). That call rewrites the DACL of every matching file in the subtree, not only the target's DACL. - If one subdirectory is inaccessible,
/savecan exit non-zero. The fail-closed check then depends on a dump that may not contain the target's own entry.

…n the second attempt
Regression: the suite covered both restore attempts failing, but not the retry actually working - the
branch where the first /restore fails transiently and the retry restores the descriptor, after which the
backup is no longer the recovery artifact and is removed.
Test drives execFile so /save succeeds, the first /restore fails and the retry succeeds, then asserts one
/save, two /restore calls, the commit rename ran, and the .bak was unlinked.
Negative control as measured: forcing the retry guard at safeWriteText.ts:548 to false turns exactly one
test red - this one. An earlier attempt to mutate the runner call at :216 produced a collection error
('no tests'), which is not a control; the guard mutation is the valid one.

_dumpIsUsable requires the saved icacls dump to be a regular, non-empty file. The suite covered a missing dump and an empty one, but not the case where the path exists with bytes in it and is not a regular file (a directory, FIFO or device planted by another process) - restoring a descriptor from such a path is not a restore of ours, so the write must fail closed. Test makes statSync report isFile() false with size 4096 and asserts the failure and that no publish rename happens. Negative control as measured: relaxing _dumpIsUsable to 'st.size > 0' (dropping the isFile() requirement at safeWriteText.ts:203) turns exactly one test red - this one. Local: safeWriteText.spec 77 passed / 1 skipped; src-level tsc --noEmit 0; eslint 0 err / 0 warn.

Learning: For Zoo-Code-Org/Zoo-Code PR #1395, src/utils/safeWriteJson.ts intentionally supports leaf-symlink targets by resolving and publishing at the referent. Locking, merge reads, staging, and publication use the canonical path to preserve the alias and coordinate alias/referent writers. Do not require blanket rejection of leaf symlinks. The user assigns storage-root confinement to confineTo in file-safety units U4/U6, tracked separately in easonLiangWorldedtech/Zoo-Code#41. The cited _refuseSymlinkedAncestors guard at commit 17c736ecb is an opt-in refuseSymlinkTarget policy and is not present at PR #1395 head 6df83d845.

Timestamp: 2026-10-08T12:37:36.839Z
Learning: In src/integrations/editor/DiffViewProvider.ts, DiffViewProvider.saveDirectly intentionally requires a writable parent directory because it uses safeWriteText for atomic rename-based publication. Do not request an in-place fs.writeFile fallback for a writable target in a non-writable directory; that fallback would discard the intended atomicity. The caller separately checks fs.access with fsConstants.W_OK to reject existing non-writable targets and permits ENOENT for new targets.

Learning: For Zoo-Code-Org/Zoo-Code PR #1395, keep the changed-code assessment focused on safeWriteText, safeWriteJson, DiffViewProvider, and their changed tests. RooIgnoreController.validateAccess is not modified by this PR; an independent concern in that controller requires separate validation rather than inclusion as a defect introduced by this PR.

Learning: For PR #1395 in Zoo-Code-Org/Zoo-Code, the author defines post-commit Windows DACL restore failure in src/services/file-safety/safeWriteText.ts as a warning rather than a generic write failure. The stated reason is to prevent callers from treating committed content as an uncommitted write and running editor-side rollback. A change to surface a post-commit error must include caller handling that distinguishes committed content from pre-commit failure. This contract does not imply that DACL preservation is confirmed.

Timestamp: 2026-10-08T16:32:43.821Z
Learning: For PR #1395 in Zoo-Code-Org/Zoo-Code, the author defines a cross-session cleanup queue or reaper for safeWriteText artifacts in src/services/file-safety/safeWriteText.ts as a separate persistence-series task tracked in easonLiangWorldedtech/Zoo-Code#41. It requires a cross-session store and a designated reaper owner. The current PR uses bounded cleanup retries and warnings that identify leftover paths; do not require an unrelated cross-session reaper implementation in this unit.

… its failure The rollback path cleaned the staging temp with an unlink whose error was discarded, so a transient EBUSY/EPERM left the temp inside the staging directory and nothing ever reported the retained path. Use the bounded retry already used for the DACL dump and backup cleanup: two attempts, ENOENT counts as already released, and a persistent failure warns once naming the retained path. Tests: a transient failure is retried and stays silent; a persistent failure warns exactly once. Both drive the rollback path by making the publish rename reject with EBUSY and count only unlinks under .file-safety-staging - an earlier filter on the temp prefix also matched the DACL dump and produced a count that could not be interpreted. Negative control as measured: restoring the single swallowing unlink turns exactly two tests red - these two. Local: safeWriteText.spec 79 passed / 1 skipped; src-level tsc --noEmit 0; eslint 0 err / 0 warn on both files.

Assert the retained temp path in the warning.
The persistent-failure test counts two staging unlink attempts, but it checks only the warning prefix. Capture the staged path from the rename call and assert that both unlink attempts and the warning use that exact path.

Summary
S3 of the file-write safety series (plan: easonLiangWorldedtech/Zoo-Code#33), part of epic #1375. Introduces the atomic text publish primitive (A4): agent file writes now go temp → fsync → close → atomic rename, so a crash or power loss mid-write can never leave a torn file at the target path. The primitive generalizes the staging/backup/rollback logic currently inline in
safeWriteJson(refactored to delegate to it), andDiffViewProvider.saveDirectly(the path all five write tools use) switches from rawfs.writeFileto it.Changes
src/services/file-safety/safeWriteText.ts(new):safeWriteText(filePath, content, options?)backup: truekeeps the old-file semantics (target → backup before commit; backup deleted on success, restored on failure); default is plain atomic replace.fs.realpathfirst (falling back to the given path when it does not exist), so a write through a symlink replaces the referent's content and never replaces the link itself.icacls /save <target> /Tbefore the backup rename, then restores it onto the target's directory after the commit rename. Any failure skips DACL handling entirely (the write is never blocked) and the dump file is always unlinked.try/finally, so a failing write/fsync never leaks one.platform,execFileRunner,tempPath) keep both platform branches testable without a Windows runner;tempPathlets a caller pre-write (streaming) then fsync+commit.src/utils/safeWriteJson.ts: the commit step now delegates tosafeWriteTextwith the pre-written stream temp (tempPath) andbackup: false(the JSON path already manages its own backup); rollback/cleanup logic unchanged.src/integrations/editor/DiffViewProvider.ts:saveDirectlywrites viasafeWriteTextinstead of rawfs.writeFile— crash/power-loss safe for every agent write.Tests
safeWriteText.spec.ts: staging/fsync/close/rename ordering; torn-write failure leaves the target byte-identical with no temp behind; backup rollback restores the old file; target-absent withbackupcommits without a backup; win32 DACL save-before-rename / restore-after-commit ordering, the skip-entirely path when the target is absent, and dump cleanup on failure; a symlink-resolution test (runs on all platforms) proving the commit rename targets therealpathresult (the referent) and never the link path, plus a realpath-failure fallback case; pre-writtentempPathcommit.DiffViewProvider.spec.ts: save-path assertions moved from rawfs.writeFileto the mockedsafeWriteTextprimitive.safeWriteJsonsuite unchanged (behavior-preserving refactor).Notes
