 - Web access and i18n are stored in the initial SQLite schema. HTTP defaults to working session/CSRF cookies without Secure and without HSTS; HTTPS enforcement is explicit.
 - Lifecycle failures retain a bounded diagnostic record separate from Audit. The restricted agent captures Docker inspection state (including exit/OOM/timestamps/health) and a bounded log tail after a failed start; the application persists this record under the operation ID and writes a stable `DGM-*` error category. Existing SQLite stores receive the additive diagnostic table at open time.
