+# Phase 4 Plan 04: Wizard Wiring Summary
+
+**ReviewStep wired as step index 3 in App.tsx and 'Review' added as fourth STEP_LABELS entry, completing the full 4-step wizard end-to-end with 98 tests GREEN**
+
+## Performance
+
+- **Duration:** 1 min
+- **Started:** 2026-03-27T10:55:00Z
+- **Completed:** 2026-03-27T10:56:00Z
+- **Tasks:** 1
+- **Files modified:** 2
+
+## Accomplishments
+
+- Added `import { ReviewStep }` to App.tsx and appended `<ReviewStep key="review" />` as steps[3]
+- Updated STEP_LABELS in StepIndicator.tsx from 3 to 4 entries: `['Backend', 'Remote Config', 'Deployment', 'Review']`
+- Updated header comment to reflect 4-step flow: `1.Backend > 2.Remote Config > 3.Deployment > 4.Review`
+- Removed obsolete "phase 4 will add step 3" comment from App.tsx clamp guard
+- Full npm test suite: 98 tests across 12 files — all GREEN
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Wire ReviewStep into App.tsx and add 'Review' label to StepIndicator** - `035c170` (feat)
+
+**Plan metadata:** (docs commit follows)
+
+## Files Created/Modified
+
+- `src/App.tsx` - Added ReviewStep import, added steps[3], removed obsolete comment
+- `src/components/wizard/StepIndicator.tsx` - STEP_LABELS extended to 4 entries, header comment updated
+
+## Decisions Made
+
+- No logic changes needed in App.tsx — the existing `Math.min(state.currentStep, steps.length - 1)` clamp automatically handles 4 steps. Plan was precisely correct.
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Issues Encountered
+
+None. The pre-existing TypeScript build errors in test files (rclone-conf.test.ts, rmm-script.test.ts) are unrelated to this plan's changes and were present before execution.
+
+## User Setup Required
+
+None — no external service configuration required.
+
+## Next Phase Readiness
+
+- Full 4-step wizard flow is now navigable end-to-end: Backend -> Remote Config -> Deployment -> Review
+- ReviewStep renders OutputBlock with CopyButton, ZipDownload, and security checkbox gate
+- All 11 requirements (CONF-02, CONF-03, DOWN-01 through DOWN-06, SECU-01 through SECU-03) are satisfied
+- Phase 4 is complete — ready for any future phase
