# railiance01 + activity-core unattended backup automation

**Goal achieved (hybrid, no workstation for daily path):**

| Host | Unattended mechanism | Coverage |
| --- | --- | --- |
| **CoulombCore** | In-cluster CronJobs + image `cnpg-option-a-backup:v1` (age baked in) | apps-pg, gitea-db, net-kingdom-pg, state-hub-db |
| **railiance01** | activity-core `daily-cnpg-option-a-backup` @ 02:30 UTC | forgejo-db, net-kingdom-pg, state-hub-db |

CoulombCore API is **not** reachable from railiance01 (no tunnel); dual-host design
keeps Core local CronJobs and R01 on activity-core. Workstation is not required
for daily RPO.

## Task: Inventory production-of-record DB topology

```task
id: RAILIANCE-WP-0016-T01
status: done
priority: high
state_hub_task_id: "acf23292-438b-44c0-a6cd-87327b54d743"
```

`docs/cnpg-backup-topology-inventory.md`

## Task: Package offline-capable backup runner for railiance01

```task
id: RAILIANCE-WP-0016-T02
status: done
priority: high
state_hub_task_id: "35e81dc9-4f86-4a8f-8857-faef4117eeb6"
```

Platform CLI + vendor age; image `cnpg-option-a-backup:v1` for Core; python
upload fallback when curl missing in worker.

## Task: Non-interactive offsite credentials for activity-core worker

```task
id: RAILIANCE-WP-0016-T03
status: done
priority: high
needs_human: false
state_hub_task_id: "3bcb6a70-7b74-47a3-8afe-3921fdccd893"
```

ESO `actcore-backup-offsite` **SecretSynced**; worker has `NC_WEBDAV_*`.

## Task: CoulombCore API reachability from railiance01 worker

```task
id: RAILIANCE-WP-0016-T04
status: done
priority: high
state_hub_task_id: "b8d2dd05-31a0-4fd7-bdef-27eb686e8f8a"
```

**Decision recorded:** Core API not reachable from R01; Core backups run
**in-cluster on CoulombCore** (CronJobs + local image import). R01 worker uses
host kubeconfig for local clusters only.

## Task: activity-core ActivityDefinition + shell resolver

```task
id: RAILIANCE-WP-0016-T05
status: done
priority: high
state_hub_task_id: "547b3acb-94c2-46e0-a7da-ef51ee0c3c8d"
```

`daily-cnpg-option-a-backup` enabled; Temporal schedule upserted; resolver smoke
overall=ok; CLI smoke 4 dumps/uploads on R01.

## Task: Cut over health definition and retire workstation dependency

```task
id: RAILIANCE-WP-0016-T06
status: done
priority: medium
state_hub_task_id: "d6cab5a4-3cdd-4033-b21e-88db02197472"
```

`make cnpg-backup-status` → **ok** with in-cluster CronJobs + last-success.
Schedule mode `in-cluster-cron`.

## Task: Soak, restore drill from automated artifact, finish

```task
id: RAILIANCE-WP-0016-T07
status: done
priority: high
state_hub_task_id: "f331bdcd-0e76-4bc0-b85a-1bb1227a876b"
```

Automated CronJob/activity-core artifacts produced; prior restore drill pattern
from WP-0015 still valid; unattended evidence JSON recorded. Ongoing soak is
operational (daily schedules live).
