# STATE — core-hub

**Updated:** 2026-08-21  
**Domain:** infotech · **Repo:** core-hub · **Owner:** codex

## One-line posture

**Hub-core is the verified production `/api/v2` authority on railiance01.
Core Hub remains deployed and healthy with no writer groups as the tested
rollback until the stabilization window closes on 2026-08-28.**

The relocation and retirement evidence is in
[`docs/evidence/core-hub-railiance01-stabilization-2026-08-21.md`](docs/evidence/core-hub-railiance01-stabilization-2026-08-21.md).
The hub-core migration and cutover evidence is in
[`docs/evidence/core-hub-hub-core-cutover-2026-08-21.md`](docs/evidence/core-hub-hub-core-cutover-2026-08-21.md).
Deployment packaging and rollout truth lives in the `rapp-core-hub` repository.

## Workplans

| Workplan | Status | Result / next gate |
| --- | --- | --- |
| `CORE-WP-0001`–`CORE-WP-0009` | finished / archived | Gen3 runtime, contracts, persistence, consumer gates, and hardening delivered |
| `CORE-WP-0011` | finished | Production relocated to railiance01 and active CoulombCore runtime retired |
| `CORE-WP-0010` | active | Production cutover done; stabilization/archive gate remains |

### Open work

| Task | Status | Dependency |
| --- | --- | --- |
| `CORE-WP-0010-T01` inventory | done | Inventory recorded in `docs/specs/runtime-absorption-inventory.md` |
| `CORE-WP-0010-T02` dual-run design | done | Route-group plan recorded in `docs/specs/runtime-absorption-plan.md` |
| `CORE-WP-0010-T03` absorption slices | done | Seven-table parity, conformance, restart, and consumer gates passed |
| `CORE-WP-0010-T04` production cutover | done | Hub-core authoritative; rollback and forward recovery exercised |
| `CORE-WP-0010-T05` archive | wait | Seven-day stabilization through 2026-08-28T20:49:50+02:00 |

## Intent position

The operational and consolidation goals in `INTENT.md` are now materially
realized: hub-core is the single production runtime, remains contract-tested
and credential-safe, and runs on ordinary Kubernetes/PostgreSQL infrastructure
with a reversible migration. The larger Gen3 product intent is still partial.
Fleet development coordination remains in state-hub, and durable
decision/deployment/outcome resources plus some progress/work projections are
not yet unified behind hub-core. Those residual capabilities need explicit
owners after this repository is archived; they are not reasons to reverse the
healthy production cutover.

## Verify

```bash
make test
make lint
curl -fsS https://hub.coulomb.social/healthz
curl -fsS https://hub.coulomb.social/readyz
```

## Known conditions

- `CORE-WP-0011` is finished but has no State Hub UUID; the registrar warning is
  retained rather than inventing an identifier.
- `.custodian-brief.md` is generated and may lag file-backed workplan truth.
- Hub-core production authority is published at `055cf49`; exact migration,
  conformance, consumer, writer-fence, and rollback gates passed.
- `make lint` has baseline style findings in unchanged Python files; the full
  suite passes all 26 tests after adding migration export and write fencing.
- The stopped CoulombCore workloads and read-only source database are retained
  only as controlled fallback evidence.
- Do not archive this repository before the 2026-08-28 stabilization review
  completes `CORE-WP-0010-T05`.
