# Runtime absorption into hub-core and archive

## Goal

Move production framework responsibility from this repository into the
consolidated **hub-core runtime**, preserve `/api/v2` consumer compatibility
through dual-run, then **archive core-hub** read-only with evidence.

Parent project: `prj-state-hub-retirement`. Depends on **HUB-WP-0004**.

## Sequencing decision — 2026-08-20

The CoulombCore decommission does not force the unresolved hub-core
library-vs-thin-host decision. Production continuity is decoupled through
`CORE-WP-0011`, which moves the existing Core Hub service to railiance01
first. This workplan remains proposed until `HUB-WP-0004` settles the durable
runtime boundary; absorption must not sit on the critical path for leaving
CoulombCore.

## Inventory runtime surfaces to absorb

```task
id: CORE-WP-0010-T01
status: todo
priority: high
state_hub_task_id: "ce21c47f-ad66-4cd1-bd8b-c8fb92da3075"
```

List routes, models, widgets, manifests, consumer smokes, and deploy assets that
must move or remain as historical fixtures. Cross-check Inter-Hub inventory and
ops-hub bootstrap.

## Dual-run design

```task
id: CORE-WP-0010-T02
status: todo
priority: high
state_hub_task_id: "d2679b41-01e9-477c-9d8a-0b1ddc8847cf"
```

Define how hub-core serves equivalent `/api/v2` (or compatible gateway) while
core-hub remains rollback. Include feature flags, traffic shift, and smoke
ownership.

## Execute absorption slices

```task
id: CORE-WP-0010-T03
status: todo
priority: high
state_hub_task_id: "c01ddec1-5737-4115-ac73-c402ffb5bdc5"
```

Migrate in slices with consumer smokes (ops-hub, activity-core) after each.
Record row counts and fixture replays per slice.

## Cutover production traffic

```task
id: CORE-WP-0010-T04
status: todo
priority: high
state_hub_task_id: "dc414053-a896-4bf0-af05-944b7a7cf750"
```

With operator approval, point production at hub-core runtime; verify consumer
smokes and interaction evidence path.

## Archive repository

```task
id: CORE-WP-0010-T05
status: todo
priority: medium
state_hub_task_id: "16525001-f85e-4dae-9dc4-d36cb1eb4fbe"
```

Write completion record (revisions, PRs, residual owners), set read-only archive
on forge, and hand residual work as live records outside this repo.

## Acceptance

- [ ] Absorption inventory complete
- [ ] Dual-run design approved/recorded
- [ ] Consumer smokes pass on hub-core host
- [ ] Production traffic cut over with evidence
- [ ] core-hub archived read-only; residuals owned elsewhere
