) -> Result<Option<i64>, SnapshotError>
Expand description

Inspect objects.db to decide whether a pre-migration snapshot is warranted. Returns Some(found_version) if an existing DB is behind current; None for fresh installs (no file) or same-version opens. A newer-than-current DB is left alone — the safety lock in wstore.rs will refuse to open it before any migration runs.
