+# 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
