# 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: "c6f6d2c5-4df2-5f8a-a838-76e4a0cb2974"
```

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: "9743357c-d32d-5508-845e-d341fd611c49"
```

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: "b57b5135-7e77-5cbe-9da8-fa226e43a0a5"
```

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)
