provides:
- GET /api/tenants/{tid}/devices/{did}/config-history endpoint
- get_config_history service function with pagination
affects: [06-02, frontend-config-history]

# Phase 6 Plan 1: Config History Timeline Summary
**GET /config-history endpoint returning paginated change timeline with component, summary, timestamp, and diff metadata via JOIN query**
## Performance
- **Duration:** 2 min
- **Started:** 2026-03-13T03:58:03Z
- **Completed:** 2026-03-13T04:00:00Z
- **Tasks:** 2
- **Files modified:** 4
## Accomplishments
- Config history service querying router_config_changes JOIN router_config_diffs for timeline entries
- REST endpoint with viewer+ RBAC and config:read scope enforcement
- 4 unit tests covering formatting, empty results, pagination, and ordering
- Router registered in main.py alongside existing config routers
## Task Commits
Each task was committed atomically:
1. **Task 1: Config history service and tests (TDD)** - `f7d5aec` (feat)
2. **Task 2: Config history router and main.py registration** - `5c56344` (feat)
## Files Created/Modified
- `backend/app/services/config_history_service.py` - Query function for paginated config change timeline
- `backend/app/routers/config_history.py` - REST endpoint with RBAC, pagination query params
- `backend/tests/test_config_history_service.py` - 4 unit tests with AsyncMock sessions
- `backend/app/main.py` - Router import and registration
## Decisions Made
- Used raw SQL text() for the JOIN query, consistent with config_diff_service.py pattern
- Pagination limit constrained to 1-200 via FastAPI Query validation
- Copied _check_tenant_access helper (same pattern as config_backups.py)
## Deviations from Plan
None - plan executed exactly as written.
## Issues Encountered
None
## User Setup Required
None - no external service configuration required.
## Next Phase Readiness
- Config history timeline endpoint ready for frontend consumption
- Plan 06-02 can build on this for detailed diff view endpoints
