#5673 "S3 client and the backup job: settings, schedule, history, metrics":
- steward/backup/s3.py: SigV4 over httpx, path-style; put and list only
(an append-only key is enough; retention is the bucket's). Signing is held
to AWS's published examples.
- steward/backup/job.py: a 15-minute tick. The daily backup goes at the hour
chosen on the reader's clock; a missed day is made up, and a failure is
retried an hour later. History of the last 30 runs, audit
(backup.made / backup.failed), and backup_age_secs / backup_bytes under
"Steward itself", resource backup, for alert rules.
- Settings → Backups: verdict first, then the bucket (secret sealed; a
blank box keeps it), the schedule, Test the bucket, Back up now, and the
recent runs.
#5675 "Docs: backing up to Archives, and restoring": docs/core/backups.md.
Also: the audit page now words the Prometheus target actions from #5668,
which showed as codes, and a guard fails on any logged action without
wording.
