+# Phase 3 Plan 01: Test Infrastructure and Wave 0 RED Baseline Summary
+
+**Vitest jsdom configured and 26 RED test stubs created covering all 7 Phase 3 requirements (WIZD-01 through WIZD-04, BACK-01 through BACK-03)**
+
+## Performance
+
+- **Duration:** 1 min
+- **Started:** 2026-03-27T09:24:50Z
+- **Completed:** 2026-03-27T09:26:26Z
+- **Tasks:** 2
+- **Files modified:** 5
+
+## Accomplishments
+
+- Configured vite.config.ts with `test: { environment: 'jsdom', passWithNoTests: true }` — React component tests can now run in jsdom without "document is not defined" errors
+- Created `src/components/wizard/` directory and 4 test stub files covering all 7 Phase 3 requirements
+- 26 tests fail RED with descriptive "not yet implemented" messages, establishing the baseline Plans 03-02 through 03-05 will drive to GREEN
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Configure Vitest jsdom environment** - `9eef937` (chore)
+2. **Task 2: Create Wave 0 test stubs RED baseline** - `153bc61` (test)
+
+## Files Created/Modified
+
+- `vite.config.ts` - Added `test: { environment: 'jsdom', passWithNoTests: true }` block
+- `src/App.test.tsx` - 3 stubs for WIZD-02 step routing
+- `src/components/wizard/BackendSelectionStep.test.tsx` - 10 stubs for WIZD-01 (card grid) and WIZD-04 (remote name validation)
+- `src/components/wizard/RemoteConfigStep.test.tsx` - 8 stubs for BACK-01 (Azure Blob), BACK-02 (S3), BACK-03 (S3-Compatible)
+- `src/components/wizard/StepIndicator.test.tsx` - 5 stubs for WIZD-03 (back navigation preserves state)
+
+## Decisions Made
+
+- No `/// <reference types="vitest" />` needed with vitest ^4.x when using `test` inside `defineConfig` — plan explicitly noted this to avoid a common mistake
+- `expect.fail('not yet implemented')` chosen over import-error approach for RED state — gives named test failures rather than file-level errors, cleaner output for Plans 03-02 through 03-05 to work against
+- Requirement IDs embedded in describe block names for direct traceability without a separate matrix
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- Test infrastructure is ready; Plans 03-02 through 03-05 can implement components and drive tests to GREEN
+- 26 failing tests provide the complete RED baseline: each plan knows exactly which stubs it must satisfy
+- No blockers
