# Fabric authority boundary for State Hub retirement

## Goal

Keep **fabric graph data authority** in fin-hub (or its specialized engine),
define any hub-core projection, and support State Hub fabric route disposition
(`move` → fin-hub).

## Confirm authority and APIs

```task
id: FIN-WP-0003-T01
status: todo
priority: high
state_hub_task_id: "4471c006-5740-4241-8c81-251134c82f0d"
```

Document which fabric entities/APIs are authoritative here vs State Hub read
models; publish consumer contract for migration.

## Migration path from State Hub fabric routes

```task
id: FIN-WP-0003-T02
status: todo
priority: high
state_hub_task_id: "76c7ed79-8614-4e42-9e4c-f50bf789b584"
```

With STATE-WP-0079, plan cutover for fabric ingest/read routes and dashboard
consumers; row-count and provenance checks.

## Optional hub projection

```task
id: FIN-WP-0003-T03
status: todo
priority: low
state_hub_task_id: "ae36e4e7-c39d-4027-bc49-e7abb52fb9e1"
```

If orientation needs a hub-core projection, define port usage without copying
authority tables into hub-core.

## Acceptance

- [ ] Authority boundary documented
- [ ] Migration path agreed with State Hub strangler
- [ ] Projection decision recorded (implement or explicitly defer)
