# W-044 Status

status: done
task: 记录操作日志和恢复

StorageWorker now validates and persists operation records with project id,
revision, payload, inverse payload and timestamp in IndexedDB's
`operation_log` store. StorageClient exposes `appendOperation`, and the
operation/inverse path has a browser regression.

Project file recovery is now separate and complete for the current save path:
an OPFS SHA-256 journal recovers interrupted staging/commit after Worker restart.

Schema 5 adds corruption quarantine. Recovery sorts validated operations by revision/time/ID,
rejects revision conflicts, opens the committed project or latest retained snapshot, and applies
only uncommitted replayable commands to the native Main. A successful save prunes committed rows.
