| GET | `/health` | Public | Liveness |
| GET | `/capabilities` | Public | Feature discovery |
| GET | `/metrics` | Public | Metrics discovery shell |
| * | `/api/v1/organizations` | JWT + `delivery.organizations.*` | CRUD + soft delete |
| * | `/api/v1/hubs` | JWT + `delivery.hubs.*` | CRUD + soft delete |
| * | `/api/v1/external-providers` | JWT + `delivery.external_providers.*` | Registration shells |
| * | `/api/v1/routing-engines` | JWT + `delivery.routing_engines.*` | Future engines ready |

## Events

| Event type | Domain / Integration | Payload summary | Version |
| --- | --- | --- | --- |
| `delivery.organization.created` | Delivery | code, name | 0.10.0.0 |
| `delivery.organization.updated` | Delivery | code | 0.10.0.0 |
| `delivery.hub.created` / `updated` | Delivery | code, organization_id | 0.10.0.0 |
| `delivery.external_provider.registered` / `updated` | Delivery | code, adapter_key | 0.10.0.0 |

## Extension Points

| Extension point | How to extend | Forbidden uses |
| --- | --- | --- |
| RoutingEngineProvider | Adapter implementing Protocol | Verticals calling routers directly |
| FleetProvider | Adapter implementing Protocol | Credentials outside Delivery |
| ExternalProviderConfig | Register adapter_key + credentials_ref | Embedding vendor SDKs in services layer |
| Capability flags | Expand `/capabilities` per phase | Claiming engines before implemented |

## Known Limitations

- No driver / fleet / dispatch / routing / tracking engines
- Event publisher is in-memory (no durable outbox drain yet)
- Metrics are discovery shells, not live counters
- Driver App / Dispatcher Panel UI deferred to frontend
- Compose health depends on postgres being available

| Alembic revision(s) | `0001_initial` |
| Upgrade steps | `python scripts/ensure_db.py && alembic upgrade head` |
| Downgrade support | `metadata.drop_all` |
| Data backfill | None |
