The new test compared the lstat target against the temp-dir claim path verbatim. The command stats the resolved real path, so on macOS (/var -> /private/var) the comparison never matched, `dev: 0n` was never injected, and the test only asserted that an ordinary archive releases its claim — which already passed before the fix. Verified: it passed with the source change reverted. Match the claim by file name instead, and count the interceptions so the test fails loudly if the mock ever goes inert again rather than silently passing. With the source change reverted the test now fails as intended. Also add the missing changeset for the user-visible fix. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

The source fix is right, and I've pushed two commits on top (rebased onto current The main one: the regression test was vacuous — it passed with your Fixed by matching the claim on file name instead, plus a counter asserting the mock actually intercepted — so it fails loudly rather than silently going vacuous again. With your source change reverted it now fails ( Also added the missing changeset, since this is a user-visible fix. On the relaxation itself — worth stating explicitly since it loosens a lock-ownership check: it's safe. The claim contents still have to match a CI is green across linux/macos/windows. |

🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy liftMake claim release conditional on the claimed object.
The identity checks are complete before
fs.unlink(claimPath). Another process can replace the lock aftercurrentAfterReadand beforeunlink. This call can then remove the new owner's claim. A later archive can run concurrently with that owner and apply conflicting spec mutations.Use a claim-release protocol that makes deletion conditional on the owned object. If the platform cannot provide that operation, retain the claim instead of unlinking a path that might have been replaced.
Based on learnings: pathname deletion after an identity check has an unresolved TOCTOU race.

Reviewed the current head. Looks good.
3 participants
Status
Ready for review at
19586c83; not merged.What was wrong
A successful Windows archive could leave
.openspec-archive.lockbehind, blocking the next archive. The open handle reported a device ID while the path stat reported0n. Closes #1949.How it was fixed
Cleanup accepts
0nas an unavailable device ID. It still checks the inode, claim contents, and path identity before unlinking.Replication / proof
The regression fails without the fix. Additional tests keep replaced or changed claims. Locally, 253 archive tests, build, TypeScript, lint, and strict change validation pass.
Notes / nits
Hosted checks for this head need fork-workflow approval. The replacement test is skipped on Windows because Windows defers deletion of open files; the release and changed-identity tests run there.
