The five steps
Plan, back up, apply, verify, recover — in record only mode. On a deployment each step runs, is verified and lands on the audit trail; every component on the demo is current, so every step reads done.
- ✓ done Plan The generator, its version and the seed are read from the provenance manifest and shown; there is nothing to confirm.
- ✓ done Back up Nothing is backed up; the manifest is the backup, and it is committed.
- ✓ done Apply Nothing is applied; a new corpus is a new generator run with a new recorded seed.
- ✓ done Verify The bundle count and the resources marked match the manifest.
- ✓ done Recover Nothing is recovered; regenerate from the recorded seed.
