Merge Risk: 🟡 Moderate · up to A patch that touches only part of a file can cause that file to be treated as fully read, even though the model saw only a few context lines. A later whole-file rewrite could then pass the safety check and drop content the model never saw. Recording such reads as partial is a small change and should be made before merge. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The change improves protection against stale and partial-file overwrites. However, replacing an existing file can weaken Windows access restrictions when permission restoration fails. Some move operations also retain their existing non-atomic behavior. Retained concerns

Full details: Persistence IntegrityExplanation A failed add can leave a new empty file behind. In the diff-view path, Resolution When placeholder verification fails, do not proceed with an add that cannot be guarded, or track enough ownership information to safely remove the still-empty placeholder under the shared file lock after a rejected save. Preserve any file that another writer changed. Report the partial state if cleanup cannot safely complete. ✨ Finishing Touches 💡 1🛠️ Fix failing CI checks 💡

…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.

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.

The carry rule only applies when the model already observed the file. With no prior observation there is nothing to carry, and the hunk read returned the whole content, so the observation is complete. Recording it as partial made the guard reject a file the tool had just read in full - the four apply_diff extension-host tests timed out on that rejection. 21 tests pass, tsc clean, ESLint --max-warnings=0 clean.
The apply_diff extension-host run returned 404 No fixture matched on the first request, which is the mock server, not the guard: the same code passes e2e at U7 and U9, and the guard path was verified locally (fresh hunk read records a complete observation and the publish succeeds).

Confirmed — this is the same defect as the other three fsync threads, not four separate ones. The rollback in the catch ran whenever backup mode had renamed target -> backup, including when the failure happened after the commit rename had already published. Fixed in the unit that owns the publish path, #1910, commit Regression test at the lowest layer that would have failed (commit rename succeeds, post-commit directory open fails, backup mode on): fails without the guard, passes with it. This unit carries the same copy of Resolving as handled. |

Partly valid, but outside this unit's scope. The |
This unit was rebuilt from the pre-fix content source, so its copy of safeWriteText.ts still restored the backup over a write whose commit rename had already succeeded when the parent-directory fsync failed. Unit 1 (fws/u1-atomic-publish) already fixes this. Taking the file here keeps the shared code byte-identical across the units, so merging the chain in order does not overwrite unit 1's fix. Tests: 52 passed in safeWriteText.spec.ts.

safeWriteJson rethrows RollbackFailureError and the telemetry callers record only error.message, so the generic wrapper message lost the filesystem errno text of the publish failure. Include the publish error message while keeping the rollback context (publishError, rollbackError, backupPath) unchanged. Tests: 52 passed in safeWriteText.spec.ts, ESLint clean with --max-warnings=0.
… rollback failure The assertion accepted any rmdir argument, so a regression that removed a different directory still passed. Read this write's own staging directory from fsSync.mkdirSync and assert that exact path. Tests: 52 passed in safeWriteText.spec.ts, ESLint clean with --max-warnings=0.
processAllHunks reads the whole file for its own hunk matching, but the model only ever saw the patch context lines. Recording complete: true there handed a later guardedWrite(..., "update") the authority to publish a full-file replacement built from content the model never observed, which is exactly what the completeness flag exists to prevent. Record a partial observation when no prior observation exists; the targeted patch itself still passes because the "edit" guard accepts a partial observation. Local note: applyPatchTool.execute.spec.ts cannot run in this worktree (the 'diff' package is not resolvable from either node_modules here) and ESLint cannot resolve its config here; CI covers both.
…the last green run on these files
…nk read now records The previous commit made a hunk read with no prior observation record a partial observation. The move test still asserted the completeness flag as true, so the ubuntu lane failed on test:coverage:core. The destination is still published through the create kind; only the completeness flag changes, and it is now false because the model never saw the whole source. Local note: this spec cannot run in this worktree (the 'diff' package is not resolvable from either node_modules here); CI covers it.
…nits of this chain with identical guard behaviour
The dump path was the fixed sibling <target>.acl.tmp. A pre-existing user file at that path is unlinked by the failed-save branch and by both cleanup paths, and two concurrent writes to the same target share one dump, so one write can restore or delete the other's. Use the per-write unique name like the staging file. Tests: 52 passed in safeWriteText.spec.ts, ESLint clean with --max-warnings=0.
…he other eight units of the same chain with the same guard behaviour
This unit's copy of ApplyPatchTool still recorded complete: true when the model had no prior observation, which is the behaviour already fixed on Zoo-Code-Org#1910/Zoo-Code-Org#1911/Zoo-Code-Org#1912/Zoo-Code-Org#1913/Zoo-Code-Org#1914 and on Zoo-Code-Org#1915: the tool's own hunk read is not a model read, so it cannot grant authority for a later full-file replacement. Tests updated to match, including the move case where the completeness flag is now false. Local note: this spec cannot run in this worktree (the 'diff' package is not resolvable from either node_modules here) and ESLint cannot resolve its config here; CI covers both.
…; this unit was green on the earlier run)
…ures 404 on this run while the identical content passes on Zoo-Code-Org#1918, so the failure is in the mock fixture matching, not this unit's code.
