+# M12-04I Status
+
+status: done
+task: release archive staging after quota/OOM and recover with a small archive
+updated: 2026-08-18 America/New_York
+enablingTask: false
+parityStateChange: false
+
+## Scope
+
+The archive recovery wrapper maps browser/OPFS quota failures to `STORAGE_QUOTA` and declared
+allocation failures to `WASM_OUT_OF_MEMORY` only after the M12-04H base transaction has removed
+staging and re-read the committed project identity. Cleanup or identity drift remains
+`STORAGE_TRANSACTION`; unrelated range and IO failures are not misclassified as OOM.
+
+Real temporary-directory tests partially write the failing payload before injecting each fault.
+Both paths leave zero staging entries and preserve the previous revision, SHA-256, and committed
+bytes. The same storage instance then accepts and atomically commits a smaller archive without a
+Worker or process restart.
+
+## Evidence
+
+- `node --test web/tests/unit/library-archive-recovery.test.mjs` passed 4/4.
+- Quota and OOM each remove a partially written 4 KiB staging payload and preserve revision 9.
+- Each failed storage instance immediately commits `small-project` at revision 10 with zero
+  staging entries.
+- `npm --prefix web run test:library-archive-cancellation` passed 6/6 and
+  `npm --prefix web run typecheck` passed.
+
+## Artifact Hashes

+- parent manifest: `7fce600a416aec5ade1a91a13d86caf4cb1f65b710054b59d525ff8b1d3c7409`

+## Next Task
+
+`M12-04J`: add malicious ZIP/TAR fixtures to the long-term security regression.
+
+## Rollback
+
+Remove the recovery wrapper, real-filesystem unit suite, manifest, and this status entry. Restore
+M12-04H as the queue tail and move the machine queue back to `M12-04I`. No parity ledger rollback is
+required.
