+# Phase 3 Plan 05: Complete Wizard Wiring Summary
+
+**DeploymentStep + StepIndicator implementation and App.tsx step router — closes the full 3-step wizard loop with breadcrumb navigation and back-navigation data preservation**
+
+## Performance
+
+- **Duration:** ~5 min
+- **Started:** 2026-03-27T08:42:00Z
+- **Completed:** 2026-03-27T08:47:00Z
+- **Tasks:** 2 completed (TDD: 4 commits), 1 pending human-verify checkpoint
+- **Files modified:** 5
+
+## Accomplishments
+
+- WIZD-02: App.tsx routes to BackendSelectionStep (step 0), RemoteConfigStep (step 1), DeploymentStep (step 2); StepIndicator always visible above current step
+- WIZD-03: StepIndicator clicking completed step dispatches SET_STEP; clicking step 0 dispatches SET_REMOTE_PARAMS({}) first to clear params without losing deployment options
+- DeploymentStep: includeInstall toggle, configPath radio group, scriptTargets checkboxes — all dispatch SET_DEPLOYMENT live on change
+- Full test suite: 87 tests GREEN across 11 test files (all requirement suites: WIZD-01, WIZD-02, WIZD-03, WIZD-04, BACK-01, BACK-02, BACK-03)
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **RED: StepIndicator WIZD-03 tests (failing)** - `7ffccfb` (test)
+2. **GREEN: DeploymentStep + StepIndicator implementation** - `273789f` (feat)
+3. **RED: App step routing WIZD-02 tests (failing)** - `b00305c` (test)
+4. **GREEN: App.tsx step router + App.test.tsx GREEN** - `8674bb8` (feat)
+
+_Task 3 (human-verify checkpoint) is pending — user must verify full wizard flow in browser_
+
+## Files Created/Modified
+
+- `src/components/wizard/DeploymentStep.tsx` — Step 2 deployment options form; includeInstall/configPath/scriptTargets dispatch SET_DEPLOYMENT live; Back/Next nav buttons
+- `src/components/wizard/StepIndicator.tsx` — 3-step breadcrumb; completed steps are clickable buttons; SET_REMOTE_PARAMS({}) dispatched on back-nav to step 0
+- `src/App.tsx` — WizardShell: routes by currentStep, StepIndicator above each step, RemoteConfigStep keyed on backendType
+- `src/App.test.tsx` — 3 WIZD-02 tests GREEN: step 0/1/2 routing verified
+- `src/components/wizard/StepIndicator.test.tsx` — 5 WIZD-03 tests GREEN: back-nav, SET_REMOTE_PARAMS, no RESET, clickable buttons
+
+## Decisions Made
+
+- **SET_REMOTE_PARAMS before SET_STEP on back-nav to step 0:** When user clicks "Backend" in breadcrumb from any step, params are cleared so the next backend selection starts fresh. Deployment options are NOT reset.
+- **App.tsx stepIndex clamp:** `Math.min(state.currentStep, steps.length - 1)` ensures step 3 (phase 4's review step) won't break the current 3-step array — forward-compatible design.
+- **TDD AppContent helper:** Tests cannot inject state into App's own WizardProvider from outside. A standalone `AppContent` component accepting `state` prop was used in a custom `TestShell` with its own WizardProvider — cleanly tests step routing without nested provider conflicts.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] App.test.tsx used `findByText(/Configure/)` matching multiple elements**
+- **Found during:** Task 2 GREEN phase (test execution)
+- **Issue:** Both StepIndicator's "2. Remote Config" label and RemoteConfigStep's h2 "Step 2: Configure Azure Blob Storage" matched `/Remote Config|Configure/` — `findByText` threw "Found multiple elements"
+- **Fix:** Changed to `findAllByText(/Configure/)` then verified `h2` element exists in results
+- **Files modified:** src/App.test.tsx
+- **Verification:** All 3 App tests GREEN
+- **Committed in:** 8674bb8 (feat commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (test assertion matching multiple elements)
+**Impact on plan:** Minimal — test logic adjusted, no behavioral change.
+
+## Checkpoint Pending
+
+Task 3 is a `checkpoint:human-verify` — the user must run `npm run dev` and manually verify the complete wizard flow end-to-end in the browser. See PLAN.md Task 3 for the full verification checklist.
