Backup Final Review Fix Report

Implemented findings

The backup container now validates that RESTIC_REPOSITORY resolves strictly below /backup, verifies that the Restic repository already has a readable configuration before a scheduled backup, and gives the explicit first-run initialization command when that preflight fails.
The backup manifest now records every successfully applied Prisma migration as a JSON object with its name and UTC completion timestamp. The psql query uses the existing DATABASE_URL connection configuration and stops on query errors.
Restore now requires BACKUP_REPOSITORY, validates that it resolves strictly below /backup, and validates the configured backup mount (including the existing writable probe) before restore-live can stop services or replace live data.
The backup runbook now documents explicit repository initialization, monthly full-read Restic checks, a disposable restore/checksum rehearsal, and post-restore Compose status/log checks.

Focused rg assertions for repository validation/preflight, migration timestamp metadata, restore mount validation, initialization, maintenance, and post-restore runbook commands.

No Docker, NAS, systemd, Restic repository, or live restore was run, per the bounded review scope. The command-level behavior is therefore statically validated only.
Existing durable STL handling, the exact live-restore confirmation flag, and rollback/safety-artifact behavior were retained.
