# Phase 10 Plan 01: Content Clarity — Intro & Step Descriptions Summary

**Intro section with Get Started CTA gates the wizard on first load; all 4 wizard steps now display 1-2 sentence context descriptions below their headings**

## Performance

- **Duration:** ~7 min
- **Started:** 2026-04-01T10:48:20Z
- **Completed:** 2026-04-01T10:54:47Z
- **Tasks:** 2
- **Files modified:** 6

## Accomplishments
- Added IntroSection component to App.tsx with action-first copy, backend list mention, and rclone.conf/script generation explanation
- Get Started button (MD3_BTN_FILLED) toggles showIntro state — intro disappears, wizard appears; no persistence
- All 4 wizard steps now have a descriptive paragraph after the h2 using MD3 secondary text styling
- Updated App.test.tsx: new "shows intro section on initial render" test + updated existing test to click Get Started before asserting wizard content

## Task Commits

Each task was committed atomically:

1. **Task 1: Add IntroSection and showIntro gate to App.tsx** - `c1d1633` (feat)
2. **Task 2: Update App.test.tsx and add step descriptions** - `4b837b1` (feat)

**Plan metadata:** _(pending final commit)_

## Files Created/Modified
- `src/App.tsx` - Added useState import, showIntro local state, IntroSection component, conditional render
- `src/App.test.tsx` - New intro test, updated BackendSelectionStep test, added fireEvent import
- `src/components/wizard/BackendSelectionStep.tsx` - Description paragraph after h2
- `src/components/wizard/RemoteConfigStep.tsx` - Description paragraph after h2
- `src/components/wizard/DeploymentStep.tsx` - Description paragraph after h2
- `src/components/wizard/ReviewStep.tsx` - Added missing h2 heading + description paragraph

## Decisions Made
- `showIntro` stored in local `useState` inside WizardShell — not in the WizardReducer. The plan explicitly required "Do NOT add intro state to useReducer/WizardState". This is purely ephemeral UI state.
- IntroSection is a local inline component in App.tsx rather than a separate file — appropriate for its small size and tight coupling to WizardShell.
- ReviewStep had no h2 heading at all. Added "Step 4: Review & Download" before the description paragraph to be consistent with the other 3 steps and satisfy "Add a `<p>` element immediately after the `<h2>`".

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 1 - Bug] ReviewStep missing h2 heading**
- **Found during:** Task 2 (adding step descriptions)
- **Issue:** ReviewStep had no `<h2>` element. The plan said "Add a `<p>` element immediately after the `<h2>`" but there was no h2 to add after. All other 3 steps had their h2.
- **Fix:** Added `<h2>Step 4: Review &amp; Download</h2>` before the description paragraph.
- **Files modified:** `src/components/wizard/ReviewStep.tsx`
- **Verification:** Tests pass, consistent structure across all 4 steps.
- **Committed in:** `4b837b1` (Task 2 commit)

---

**Total deviations:** 1 auto-fixed (missing h2 in ReviewStep)
**Impact on plan:** Necessary to fulfill the requirement as written. No scope creep.

## Issues Encountered

**Pre-existing test failures (deferred, out of scope):** 8 tests in `RemoteConfigStep.test.tsx` occasionally timeout for GCS/B2 fields and S3/GCS validation. Root cause: uncommitted working-tree changes to `registry.ts` (tooltip texts added in a prior session) combined with the updated test selectors. These failures are unrelated to plan 10-01 and do not affect any of the 6 target files. Logged to `deferred-items.md`.

Final full test run: 202/202 passing.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness
- IntroSection is live, Get Started CTA works, wizard is hidden behind it on initial load
- All 4 steps have consistent h2 + description paragraph structure
- Plan 10-02 can proceed (next content clarity improvement)
