Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔴 Critical · up to The backup publication path can delete an existing backup during a destination race, and the recovery procedure omits handling SQLite sidecar files before restoration. These issues can cause backup loss or incorrect recovery, so merging should be blocked until they are corrected. Sequence Diagram(s)sequenceDiagram

- Around line 58-60: Update the publication dates for the SQLite backup API and
VACUUM references to 2025-11-13 and 2025-07-12 respectively; alternatively,
remove the year and date from both entries to use a consistently undated
citation format.
In `@docs/operations/sqlite-backup-recovery.md`:
- Around line 45-50: The recovery procedure must preserve the original SQLite
database together with any existing -wal, -shm, and -journal sidecars as one
evidence set, then verify those sidecars are absent from the configured database
path before placing the verified backup there. Update the numbered recovery
steps accordingly, while keeping writers stopped throughout preservation and
replacement and preventing sidecars from being combined with the restored
database.
In `@server/sqlite_backup.mjs`:
- Around line 264-284: Update the cleanup logic around linkSync and the outer
catch so removeIncompleteBackupBestEffort(destinationPath) runs only when this
operation created the destination, not merely when published is false. Track
destination creation separately from published, preserving the EEXIST
no-overwrite behavior and ensuring pre-existing or concurrently created backups
are never removed.

Buyer / operator impact
ScopeWeave can create a verified live SQLite snapshot without raw-copying a WAL-backed database and without exposing a destructive restore command. Operators get a consistent backup/verify boundary plus an executable stopped-writer recovery rehearsal that proves a verified snapshot can be reopened through ScopeWeave's actual database bootstrap with customer-like rows intact.

SQLite documents
VACUUM INTOas a supported consistent snapshot mechanism and permits the target to be absent or an empty file. SQLite also warns that a live database and its WAL/journal sidecars can form one logical state, which is why raw live file copying and stale-sidecar mixing are not treated as recovery-safe boundaries.

All previously actionable CodeRabbit threads are resolved on current source, and the Cursor operator-discovery finding was addressed inREADME.mdanddocs/deploy.md; any new exact-head review finding must be revalidated before integration.There is no qualifying independent approval after the latest push.
