Merge Risk: 🔵 Low · up to The new atomic publishing path for JSON and text files appears functionally sound. Two bounded issues remain. A confined write through a symlink that points outside the allowed scope can create a lock directory outside that scope before it is rejected, and it can report the wrong error. A staged temp file may also be briefly readable at the default permissions. These are follow-ups the owners should address rather than merge blockers. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The writer improves permission preservation and recovery reporting, but changes both where configuration updates land and what a rejected write means. Project symlinks can redirect updates outside the project, and a post-commit failure can leave saved MCP disable settings inconsistent with active connections. Exposure remains bounded by the extension host’s filesystem permissions; attacker control of deployment paths is not established. Retained concerns

Resolution Do not discard the backup path after a failed cleanup. Make the cleanup failure visible and retain the path for a retry mechanism, such as a tracked orphan-cleanup queue or a startup/next-write cleanup pass. Add a test where backup creation fails and unlink also fails, and verify the orphan remains tracked and cleanup is retried. ✨ Finishing Touches🧪 Generate unit tests (beta)

- Around line 6-14: Strengthen the observation assertions in the `observe → get`
test and the corresponding test around lines 62–71: use fake timers to assert
the exact `observedAt` value, and compare the complete recorded entry with
`toEqual`, including `complete: true`, rather than relying on `toBeDefined()` or

…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.

The three findings here are the same class as the ones on #1910 and are closed in the commit that owns
50 tests pass at this head; the new lstat test was verified to fail against the pre-fix file. Re-requesting review needs a human — this token gets 404 on |
… 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 staging-identity guard read fs.Stats.ino/dev as JS numbers. On NTFS and ReFS those identifiers can exceed
Number.MAX_SAFE_INTEGER, and the rounding makes two different files look identical - a valid caller-staged file is
then rejected with StagingPathError (and a real alias could be missed). Both lstats now request { bigint: true } and
the comparison checks for bigint values before comparing them.
The spec stand-in carries bigint ino/dev, matching what lstat({ bigint: true }) returns at runtime (fs.BigIntStats is
a type-only export, so the double is documented at its single assertion).

The identity stand-in returns bigint identifiers regardless of the options, so the same-file tests could still pass if
either lstat dropped { bigint: true } - which is exactly the case that matters on NTFS/ReFS. Both tests now assert
that every identity lstat requested bigint stats.
The calls are filtered by their options rather than by path spelling: path.resolve prefixes a drive letter to
/tmp/... on Windows, so a path filter would only see one of the two reads on that platform.
…served On win32 the DACL of an existing target is saved before the commit rename so it can be reapplied afterwards. Two paths silently skipped that step and still published: - icacls /save failed (saved === false): the dump is cleaned up and the rename proceeds, so the new file inherits different access rights; - fs.access(targetPath) failed with something other than ENOENT (EACCES, ...): the catch treated "cannot check" as "target absent" and skipped DACL handling entirely. Both now report through a new onWarning sink (default console.warn): the write still proceeds - a missing or failing icacls must not leave the user unable to save, which is the documented fallback - but the caller is told the replacement may inherit different access rights instead of discovering it later. Tests: icacls save failure still commits the write and yields exactly one access-rights warning; an EACCES on the target yields the could-not-check warning and no icacls call. Verified as real regression tests - neutralizing the two warn calls makes both fail. 272 passed / 4 skipped locally; tsc and eslint clean.

onWarning is documented as the sink for non-fatal safety notices, but delivery was not isolated from the write: an onWarning callback that threw propagated to the outer failure handler before fs.rename, turning a non-fatal notice into a failed save. The warn binding now catches callback failures and logs them. The restore-failure notice is routed through the same binding so a caller supplying onWarning receives it. Same fix as the u6 unit, kept aligned across the series. Local: safeWriteText 58/58 green; eslint clean, no suppression growth.

- Around line 34-48: Rename the existing test to identify it as covering
backup-copy failure, since `backup: true` fails before the commit rename. Add a
separate test using `safeWriteText` with `backup: false` that exercises
commit-rename failure and verifies the directory contents remain unchanged and
no staging residue remains.
Review comments at @src/services/file-safety/safeWriteText.ts:
- Around line 303-306: Remove the unused committed flag and its assignment after
the rename in the safeWriteText flow. Update the catch-block rollback comments
to accurately state that the backup is only a copy that is deleted, not restored
over the target; preserve the existing cleanup behavior.
Review comments at @src/utils/safeWriteJson.ts:
- Around line 147-152: In the safe-write flow, check confinement on lockKey
after resolveLockKey and before acquireFileLock so an out-of-scope symlink is
rejected before lock creation. Keep the existing post-lock confinement check on
resolvedTargetPath to catch symlink changes.
- Around line 211-216: Update the comments in safeWriteJson around dangling-link
handling and the safeWriteText calls to describe copy-based backups accurately:
backup creation copies the target without moving it, and failure does not
restore a renamed backup. Remove the claim that backup mode moves the referent
away and back, and describe the actual target and backup cleanup behavior.

proper-lockfile creates ${lockKey}.lock beside the lock key, and the key is the
symlink referent. A repository that plants .roo/mcp.json -> ~/.ssh/config
therefore made the confined write create a lock directory OUTSIDE the declared
scope, and when that directory was not writable the caller received a
lock-acquisition error after up to five retries instead of
ConfinedPathEscapeError. The confinement check now runs on the lock key before
acquireFileLock, and is repeated on the resolved publish target inside the lock
(a peer writer may have moved the referent in between). Both checks share
_assertWithinScope so they canonicalize identically.
Also on this branch's review findings:
- Drop the unused `committed` flag in safeWriteText and describe the cleanup the
way it actually works: the backup is a copy, so a failure deletes it rather
than restoring anything.
- Correct three comments in safeWriteJson that still described the old
move-and-rollback backup (the target is never moved aside).
- Integration spec: the directory-target case is renamed to what it covers (the
backup-copy failure) and a backup:false case is added so the failing COMMIT
rename, the temp unlink and the staging removal are covered on a real
filesystem.

Series alignment for the two review findings fixed on fws/u6-apply-patch-wiring: 1. safeWriteText's warn wrapper could not catch a rejection from an async onWarning sink - TypeScript accepts a value-returning callback where a void one is expected - so the rejected promise was left unhandled, which under Node's default mode can end the process after a write that already succeeded. The wrapper now attaches a catch handler without awaiting (awaiting would let warning delivery delay a committed write, or stall it on a hung sink) and reports the rejection through the fallback sink. 2. safeWriteJson created the target's parent directory BEFORE the preflight confinement check, so a confined write to an out-of-scope path with a missing parent still created a directory outside confineTo. resolveLockKey and the check need no directory to exist, so the order is now lock key, confinement, mkdir; the in-lock check on the resolved publish target stays.

Split unit U3 of #1833, under the plan on this issue (5993969784 / 5994039786 / 5994053776). Base is U1 (#1911) per the merge order.
Scope (one gate scope): observation completeness — a partial read does not make a destination observable, and a move carries the source's completeness rather than inventing a new observation.
