## Testing

To test the implementation:

1. Start the database and Redis
2. Run migrations: `npx prisma migrate dev`
3. Start the server: `npm run dev`
4. Test API endpoints using the Swagger UI: `http://localhost:3000/api-docs`

## Protocol gaps (rails and external messaging)

Tracked checklist with gap IDs, RTGS matrix cross-reference, and suggested close order: `docs/solacenet/PROTOCOL_GAPS_CHECKLIST.md`. Governance: `docs/solacenet/RAIL_AND_PROTOCOL_GOVERNANCE.md`.

## Notes

- The Go gateway requires Go 1.21+ and Redis
- Some services use simplified implementations that should be enhanced for production
- Frontend console is not yet implemented
- Phase 3-5 capability packs are pending implementation
