From the 2026-07-10 meeting notes (New tasks).
Publishing must not publish only the latest census. Publishing census N must produce snapshot N, which contains census N plus every prior census (N-1, N-2, ..., 0).
Storage model on the SI side:
- Only snapshot N is present in the SI database at a given time.
- Prior snapshots (N-1, N-2, ..., 0) are retained as SQL backups zipped into files, not live in the DB simultaneously.
Scope to define:
- How a snapshot is assembled (full cumulative state through census N).
- Backup/zip creation and retention for superseded snapshots.
- Restore path from a zipped backup.
- Confirm this contract before building, since it shapes the export format.
