+
+| Step | Action | Result | Evidence |
+| --- | --- | --- | --- |
+| 2.1 | Pre-freeze `pg_dump` (coulombcore) | **pass** | `/tmp/state-hub-prefreeze-20260706T165001Z.dump` (3.0 MiB) |
+| 2.2 | Freeze coulombcore writer | **pass** | `deployment/state-hub` scaled to 0 |
+| 2.3 | Final `pg_dump` after freeze | **pass** | `/tmp/state-hub-final-20260706T165019Z.dump` (3.0 MiB) |
+| 2.4 | Restore into railiance01 `state-hub-db` | **pass** | DROP/CREATE `state_hub` + `pg_restore --role=state_hub` |
+| 2.5 | Exact-count comparison | **pass** | All 7 baseline tables match ±0 |
+| 2.6 | Scale railiance01 API + verify | **pass** | Forgejo `main-d1a4fcf`; `/state/health` ok |
+
+**Phase 2 status: complete.** Phase 3 (rewire access paths) not started.

+## Baseline counts (pre-freeze gate)

+
+| Cluster | API | DB writer |
+| --- | --- | --- |
+| **railiance01** | Running 1/1 (`forgejo…:main-d1a4fcf`) | **primary** (restored data) |
+| **coulombcore** | Scaled to **0** (frozen, rollback-capable) | Unchanged CNPG (source dump retained) |
+
+Workstation `http://127.0.0.1:8000` still tunnels to coulombcore — **unreachable until Phase 3**.

+
+## Rollback
+
+- coulombcore dump files retained under `/tmp/state-hub-*-20260706T*.dump` on workstation
+- Scale coulombcore `state-hub` back to 1; do **not** delete railiance01 data until Phase 5 stabilizes
+
+## Next: Phase 3
+
+- Repoint `state-hub-primary` tunnel → railiance01 ClusterIP `10.43.68.154:8000`
+- activity-core in-cluster URL; retire `fleet-state-hub-coulombcore`
+- Smoke `POST /progress/` through production path
