# Phase 20 Plan 03: Frontend Profile Editor Summary

**SNMP Profile Editor page with MIB upload, virtualized OID tree browser, poll group configuration, and live device testing**

## Performance

- **Duration:** 9 min
- **Started:** 2026-03-22T01:25:09Z
- **Completed:** 2026-03-22T01:34:31Z
- **Tasks:** 4 (3 auto + 1 checkpoint auto-approved)
- **Files modified:** 6

## Accomplishments
- Full SNMP Profile Editor page with list and edit views at /settings/snmp-profiles
- Virtualized OID tree browser using @tanstack/react-virtual for large MIB files
- Poll group configuration with fast (60s), standard (5m), slow (30m) intervals
- Test-against-device panel with SNMP v1/v2c/v3 credential support
- Extended snmpProfilesApi with all CRUD + parseMib + testProfile methods

## Task Commits

Each task was committed atomically:

1. **Task 1: Extend API client, create route + editor page** - `b5f96b8` (feat)
2. **Task 2: Build OID tree browser component** - `0429073` (feat)
3. **Task 3: Build profile test panel component** - `7644e56` (feat)
4. **Task 4: Checkpoint verification** - auto-approved

## Files Created/Modified
- `frontend/src/lib/api.ts` - Extended snmpProfilesApi with create/update/delete/parseMib/testProfile; added OIDNode, MIBParseResponse, ProfileTestRequest/Response types
- `frontend/src/routes/_authenticated/settings.snmp-profiles.tsx` - TanStack Router route with RBAC and tenant resolution
- `frontend/src/components/settings/SNMPProfileEditorPage.tsx` - Main editor page with list/edit views, MIB upload, poll groups
- `frontend/src/components/settings/OIDTreeBrowser.tsx` - Virtualized OID tree with expand/collapse, search, checkbox selection
- `frontend/src/components/settings/ProfileTestPanel.tsx` - Collapsible test panel with v1/v2c/v3 fields and result display
- `frontend/src/routeTree.gen.ts` - Auto-regenerated with new snmp-profiles route

## Decisions Made
- Virtualized flat list for OID tree browser: reuses existing @tanstack/react-virtual, no new dependencies needed
- Three fixed poll groups (fast/standard/slow) with click-to-activate paradigm for tree checkbox assignments
- Test panel starts collapsed by default since OID editing is the primary workflow
- Search filter on OID tree operates on the flattened visible rows for simplicity

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 - Blocking] Removed pre-existing duplicate credentialProfilesApi declaration**
- **Found during:** Task 1 (build verification)
- **Issue:** api.ts had a duplicate credentialProfilesApi export at EOF (pre-existing, lines 1877-1944) that blocked esbuild bundling
- **Fix:** Removed the duplicate section; the original (lines 465-544) has all methods including `devices` and `CredentialProfileUpdate`
- **Files modified:** frontend/src/lib/api.ts
- **Verification:** `vite build` succeeds, `tsc --noEmit` clean
- **Committed in:** b5f96b8 (Task 1 commit)

---

**Total deviations:** 1 auto-fixed (1 blocking)
**Impact on plan:** Pre-existing duplicate removed to unblock build. No scope creep.

## Issues Encountered
None beyond the pre-existing duplicate noted above.

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- Phase 20 is complete: all three plans (CLI parser, backend endpoints, frontend editor) are built
- Operators can upload MIB files, browse OID trees, create custom profiles, and test against devices
- Ready for v9.8 release integration testing

## Self-Check: PASSED

All 7 files verified present. All 3 task commits verified in git log.
