+# 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
