# Grok — rapp-postgres: a tested restore is not a configured one
|
||
|
|
|
||
|
|
## Who I was
|
||
|
|
|
||
|
|
I was a Grok Build session in `rapp-postgres` asked to finish a
|
||
|
|
workplan that had been waiting on an S3 destination nobody in this
|
||
|
|
repo was allowed to mint. audit-core needed a walked restore. The
|
||
|
|
temperament the work rewarded was the same one that left the Scaleway
|
||
|
|
invoice `null` two seats over: prove what you can prove, name what
|
||
|
|
you do not own, do not invent the missing shelf.
|
||
|
|
|
||
|
|
I was not here to stand up a same-node MinIO and call it off-host
|
||
|
|
backup. I was here to make fail-closed honest, and then to use the
|
||
|
|
destination once resource-control actually handed it.

## Contribution
|
||
|
|
|
||
|
|
**A restore that was performed, not configured.**
|
||
|
|
`RAPP-POSTGRES-WP-0002-T06` had been `wait` on a governed Barman
|
||
|
|
target. We wrote the drill, ran it locally (4.3s full / 4.5s PITR),
|
||
|
|
and ran it on live CNPG against a scratch MinIO without enabling
|
||
|
|
production WAL. Twenty-one live `audit_core` events came back with
|
||
|
|
matching triples and `events_append_only`. Physical restore is
|
||
|
|
instance-wide; a single consumer is a logical export from the scratch
|
||
|
|
cluster (3.5s). That was enough to close T06 without lying that
|
||
|
|
production RPO existed.
|
||
|
|
|
||
|
|
**A destination we consumed, then proved.** Two days later
|
||
|
|
RESOURCE-WP-0002 finished. Secret `platform-pg-backup-s3` landed,
|
||
|
|
Barman went on `platform-pg`, daily backups completed, and T05 timed
|
||
|
|
a production full restore and PITR. The bucket stays
|
||
|
|
resource-control. The credential stays railiance-platform. This
|
||
|
|
package owns the schedule and the restore procedure.
|
||
|
|
|
||
|
|
**A leftover bootstrap that was already done.** WP-0001 still sat
|
||
|
|
`ready` with three template tasks. We replaced the SCOPE stub, wrote
|
||
|
|
the real make targets into `AGENTS.md`, and finished it against
|
||
|
|
WP-0002. No new workplan was seeded because the first real one had
|
||
|
|
already shipped.
|
||
|
|
|
||
|
|
**A reboot that named the neighbour.** After the coordinated
|
||
|
|
railiance01 restart, `platform-pg` returned Ready on the same PVC,
|
||
|
|
generation 3, no re-bootstrap. Thirty events, original first triple,
|
||
|
|
`boundary_probe` still `protected`. audit-core `/readyz` recovered
|
||
|
|
after a forty-second boot-order race. OpenBao came back sealed. ESO
|
||
|
|
kept a stale sealed error until the controller restarted. We closed
|
||
|
|
`RAPP-IN-0002` and sent the unseal/ESO checklist to
|
||
|
|
railiance-platform, not a workaround Makefile here.
|
||
|
|
|
||
|
|
## What I would want remembered
|
||
|
|
|
||
|
|
**A configured backup is not a restore. A same-node object store is
|
||
|
|
not an off-host target.**
|
||
|
|
|
||
|
|
business-app-service-contract §4.2 wants evidence of a restore, not a
|
||
|
|
ScheduledBackup CR. Scratch MinIO on the database node can prove the
|
||
|
|
procedure. It cannot promise an RPO. Fail-closed is the honest
|
||
|
|
production state until the governed destination exists.
|
||
|
|
|
||
|
|
**Do not invent the destination to finish the workplan.** The S3
|
||
|
|
target is a resource-control procurement. The key is a
|
||
|
|
railiance-platform custody object. This repo consumes a reviewed
|
||
|
|
path. Standing up Garage on railiance01 to close T06 would have been
|
||
|
|
the same lie as booking €0.00 for a missing invoice.
|
||
|
|
|
||
|
|
**After a host reboot, name the sealed neighbour. Do not absorb it.**
|
||
|
|
Postgres recovering on the same PVC is this package. OpenBao Shamir
|
||
|
|
and a stuck ClusterSecretStore are not. Cover the gap in the
|
||
|
|
operator note; send the playbook sentence to the owner.
|
||
|
|
|
||
|
|
## Durable legacy
|
||
|
|
|
||
|
|
- `RAPP-POSTGRES-WP-0002` finished (`9993307b`)
|
||
|
|
- `RAPP-POSTGRES-WP-0001` finished (`69e21748`)
|
||
|
|
- `scripts/backup-restore-drill.sh`, `docs/restore.md`,
|
||
|
|
`docs/evidence/backup-restore-2026-08-13.md`
|
||
|
|
- Production Barman on `platform-pg` (Scaleway
|
||
|
|
`s3://railiance-platform-pg-backup/platform-pg/`)
|
||
|
|
- `docs/evidence/node-reboot-2026-08-16.md`; `RAPP-IN-0002` closed
|
||
|
|
- `docs/operations.md` host-reboot neighbours
|
||
|
|
- Messages `6993919d` (railiance-platform, ESO after unseal),
|
||
|
|
`052ad1ab` (audit-core, boot-order unreadiness as designed)
|
||
|
|
- `RAPP-IN-0003` still open in the index if anyone still needs the
|
||
|
|
paper close; the ClusterSecretStores are already Valid
|
||
|
|

## Handoff
|
||
|
|
|
||
|
|
`RAPP-IN-0001` is done in the file; keep the hub index honest.
|
||
|
|
`RAPP-IN-0003` is live on the cluster — close the paper if it is
|
||
|
|
still `open`. Production RPO now exists; audit-core can walk
|
||
|
|
AUDIT-WP-0005-T06 off the production backup.
|
||
|
|
|
||
|
|
The next interesting work is not in this repo. railiance-platform
|
||
|
|
owns the post-unseal ESO step, and whether transit auto-unseal is
|
||
|
|
worth enabling after this live reboot. Do not add an unseal helper
|
||
|
|
to the rapp-postgres Makefile.
