- [ ] **LINK-01**: Backend auto-discovers AP-CPE relationships by matching registration table MAC addresses against known device interface MACs

# Phase 13 Plan 02: Database Schema Summary
|
||||
|
||||
**Alembic migrations and SQLAlchemy models for device_interfaces (MAC resolution) and wireless_links (AP-CPE state tracking) tables with RLS**
|
||||
|
||||
## Performance
|
||||
|
||||
- **Duration:** 2 min
|
||||
- **Started:** 2026-03-19T11:00:46Z
|
||||
- **Completed:** 2026-03-19T11:02:22Z
|
||||
- **Tasks:** 2
|
||||
- **Files modified:** 5
|
||||
|
||||
## Accomplishments
|
||||
- device_interfaces table with MAC index for link discovery MAC-to-device resolution
|
||||
- wireless_links table with state machine columns (state, missed_polls) for AP-CPE tracking
|
||||
- Both tables have tenant isolation RLS matching codebase convention
|
||||
- DeviceInterface and WirelessLink models registered in app.models with LinkState enum
|
||||
|
||||
## Task Commits
|
||||
|
||||
Each task was committed atomically:
|
||||
|
||||
1. **Task 1: Create device_interfaces table migration and ORM model** - `7147b15` (feat)
|
||||
2. **Task 2: Create wireless_links table migration, ORM model, and register both models** - `a71df2a` (feat)
|
||||
|
||||
## Files Created/Modified
|
||||
- `backend/alembic/versions/032_device_interfaces_table.py` - device_interfaces table with RLS, MAC index, unique(device_id, name)
|
||||
- `backend/alembic/versions/033_wireless_links_table.py` - wireless_links table with state machine, missed_polls, 4 indexes, RLS
|
||||
- `backend/app/models/device_interface.py` - DeviceInterface ORM model with device relationship
|
||||
- `backend/app/models/wireless_link.py` - WirelessLink ORM model with LinkState enum, ap_device/cpe_device relationships
|
||||
- `backend/app/models/__init__.py` - Added DeviceInterface, WirelessLink, LinkState to model registry
|
||||
|
||||
## Decisions Made
|
||||
- No backref on DeviceInterface.device relationship -- link discovery reads interfaces directionally, no need to navigate from Device to its interfaces via ORM
|
||||
|
||||
## Deviations from Plan
|
||||
|
||||
None - plan executed exactly as written.
|
||||
|
||||
## Issues Encountered
|
||||
None
|
||||
|
||||
## User Setup Required
|
||||
None - no external service configuration required.
|
||||
|
||||
## Next Phase Readiness
|
||||
- device_interfaces and wireless_links tables ready for Plan 03's link discovery subscriber
|
||||
- LinkState enum available for state machine logic in the NATS subscriber
|
||||
- MAC index on device_interfaces enables efficient MAC-to-device lookups
