+# Phase 13 Plan 04: RemoteConfigStep Full Backend Integration Summary
+
+**RemoteConfigStep wired for all 18 backends: GdriveAuthToggle for gdrive, OAuthInstructions for onedrive/dropbox/box/pcloud, generic FieldRenderer loop for all others, with registry-derived backendLabel**
+
+## Performance
+
+- **Duration:** ~15 min
+- **Started:** 2026-04-01T16:50:00Z
+- **Completed:** 2026-04-01T17:00:00Z
+- **Tasks:** 2 of 3 (Task 3 is human visual verification checkpoint)
+- **Files modified:** 2
+
+## Accomplishments
+- Replaced manual `backendLabel` record with `Object.fromEntries(BACKEND_REGISTRY)` derivation
+- Refactored 3-branch ternary into `renderBackendFields()` switch function (7 branches + default)
+- Added gdrive branch: GdriveAuthToggle + generic loop for non-auth fields (root_folder_id)
+- Added onedrive branch: OAuthInstructions + generic loop
+- Added dropbox, box, pcloud branches: each with OAuthInstructions + generic loop
+- Default case handles remaining backends: azure-files, swift, ftp, webdav, smb, http, seafile, s3, s3-compatible, gcs, b2
+- 6 new tests added for new backend form rendering — all 282 tests pass
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Wire all new backends into RemoteConfigStep** - `d0c00f7` (feat)
+2. **Task 2: Add tests for new backend form rendering** - `2c596c9` (test)
+3. **Task 3: Visual verification** - awaiting human checkpoint
+
+## Files Created/Modified
+- `src/components/wizard/RemoteConfigStep.tsx` - Refactored with switch-based renderBackendFields(), registry-derived backendLabel, imports for GdriveAuthToggle and OAuthInstructions
+- `src/components/wizard/RemoteConfigStep.test.tsx` - 6 new test cases for gdrive, dropbox, ftp, webdav, smb, http backends
+
+## Decisions Made
+- `renderBackendFields()` switch statement chosen over nested ternaries — 7 branches makes ternary chains unreadable
+- `backendLabel` derived from registry via `Object.fromEntries` — eliminates the manual duplication risk (Pitfall 2 in research)
+- Test label selectors use partial regex (e.g. `/host/i` not `/^host$/i`) because `TextFieldMD3` appends a `*` span to required field labels, making exact-anchor matches fail
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Test label selectors fixed for TextFieldMD3 required field suffix**
+- **Found during:** Task 2 (TDD RED phase)
+- **Issue:** Plan specified tests like `getByLabelText(/^host$/i)` but TextFieldMD3 renders required field labels as "Host*" (with a `<span>*</span>`), so anchored regex `/^host$/i` fails to match the full label text
+- **Fix:** Changed anchored patterns (`/^host$/i`) to non-anchored partial patterns (`/host/i`) in all affected test assertions
+- **Files modified:** src/components/wizard/RemoteConfigStep.test.tsx
+- **Verification:** All 6 new tests pass; full suite 282/282 green
+- **Committed in:** 2c596c9 (Task 2 commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (Rule 1 - Bug)
+**Impact on plan:** Minor selector correction needed for test compatibility with existing TextFieldMD3 pattern. No scope creep.
+
+## Issues Encountered
+None beyond the test selector adjustment documented above.
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Tasks 1 and 2 complete: all 18 backends render correct forms
+- Task 3 (visual verification) awaiting human approval
+- Once approved, Phase 13 is fully complete — all 18 backends functional end-to-end
