+
+**Site column in fleet table with multi-select bulk assign, site selector on device detail, and DeviceResponse site fields**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-03-19T02:49:59Z
+- **Completed:** 2026-03-19T02:53:16Z
+- **Tasks:** 2
+- **Files modified:** 5
+
+## Accomplishments
+- DeviceResponse now includes site_id and site_name on backend and frontend
+- Fleet table has checkbox column for multi-select with bulk "Assign to site" action
+- Fleet table has Site column showing clickable site name links (or "--" for unassigned)
+- Device detail page has site selector dropdown for assign/change/remove site
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add site_id and site_name to DeviceResponse** - `ddb2b3e` (feat)
+2. **Task 2: Add Site column, multi-select bulk assign, and site selector** - `98e328c` (feat)
+
+## Files Created/Modified
+- `backend/app/schemas/device.py` - Added site_id and site_name optional fields to DeviceResponse
+- `backend/app/services/device.py` - Added site fields to _build_device_response, selectinload(Device.site) to eager loading
+- `frontend/src/lib/api.ts` - Added site_id and site_name to DeviceResponse interface
+- `frontend/src/components/fleet/FleetTable.tsx` - Checkbox column, Site column, multi-select state, bulk assign dialog
+- `frontend/src/routes/_authenticated/tenants/$tenantId/devices/$deviceId.tsx` - Site selector dropdown with assign/unassign mutation
+
+## Decisions Made
+- Site column placed after Model column for logical grouping of device identity fields
+- Viewers see site name as plain text; operators get a Select dropdown for changing assignment
+- Bulk assign uses a Dialog component with site selector and mutation pattern
+
+## 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-site relationship fully wired end-to-end (backend model, API, frontend views)
+- Site detail page ready for Phase 14 dashboard expansion with device list
+- All site management features operational: CRUD, assign, unassign, bulk assign
+
+## Self-Check: PASSED
+
+All 5 modified files verified on disk. Both task commits (ddb2b3e, 98e328c) verified in git log.
