# Dependency graph
requires:
  - phase: 05-00
    provides: TDD stubs for TECH-01 and TECH-02 test cases in ReviewStep.test.tsx
provides:
  - ReviewStep conditionally renders Intune and RMM OutputBlocks based on scriptTargets
  - ZIP bundle filtered to only include files for selected script targets
  - Back button on ReviewStep dispatching SET_STEP(2)

# Tech tracking
tech-stack:
  added: []
  patterns:
    - "scriptTargets.includes() boolean derivation drives conditional rendering (unmount, not CSS)"
    - "handleDownloadZip builds files array dynamically from showIntune/showRmm booleans"
    - "Back button pattern from DeploymentStep: dispatch SET_STEP(payload) in onClick"

key-files:
  created: []
  modified:
    - src/components/wizard/ReviewStep.tsx

key-decisions:
  - "Unmount OutputBlocks entirely (conditional render with &&) — not CSS hidden — so no stale state is preserved when toggling"
  - "useMemo calls for intuneInstall/intuneDetection/rmmScript are KEPT even when blocks are hidden — needed for ZIP handler"
  - "rclone.conf OutputBlock always rendered regardless of scriptTargets — only script outputs are conditional"
  - "Back button placed before ZIP button, follows identical className/dispatch pattern from DeploymentStep"

patterns-established:
  - "showIntune/showRmm boolean pattern: derive from state.deployment.scriptTargets.includes() — use same pattern in future conditional script output features"

# Phase 5 Plan 02: ReviewStep scriptTargets Filtering and Back Button Summary

**ReviewStep conditionally unmounts Intune/RMM OutputBlocks via scriptTargets booleans, filters ZIP bundle to match, and adds a Back button dispatching SET_STEP(2)**

## Performance

- **Duration:** ~4 min
- **Started:** 2026-03-30T09:36:00Z
- **Completed:** 2026-03-30T09:37:30Z
- **Tasks:** 1 (TDD: RED confirmed, GREEN implemented)
- **Files modified:** 1

## Accomplishments
- ReviewStep now reads scriptTargets from state and derives showIntune/showRmm booleans
- Intune Install and Detection OutputBlocks are conditionally unmounted (not CSS-hidden) when showIntune is false
- RMM OutputBlock is conditionally unmounted when showRmm is false
- handleDownloadZip builds its files array dynamically — ZIP always has rclone.conf, plus intune/rmm files only if selected
- Back button added following DeploymentStep pattern, dispatching SET_STEP(2)
- All 15 ReviewStep tests green (10 pre-existing + 5 new TECH-01/TECH-02 cases); 104 total tests pass with no regressions

## Task Commits

Each task was committed atomically:

1. **Task 1: Add scriptTargets filtering and Back button to ReviewStep** - `214a68e` (feat)

**Plan metadata:** (docs commit follows)

_Note: TDD task — RED state confirmed (5 failing), then GREEN via implementation._

## Files Created/Modified
- `src/components/wizard/ReviewStep.tsx` - Added dispatch destructuring, showIntune/showRmm booleans, conditional OutputBlock rendering, dynamic ZIP handler, and Back button

## Decisions Made
- Kept all useMemo calls (intuneInstall, intuneDetection, rmmScript) even when their OutputBlocks are hidden — they are referenced by the ZIP handler which always needs the content
- Used `&&` conditional render (unmount pattern) not CSS `hidden` — consistent with plan spec and avoids preserving stale component state

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- TECH-01 and TECH-02 requirements now complete — ReviewStep correctly respects scriptTargets selections
- Phase 05-03 (if any) can proceed; wizard UI is now consistent across BackendSelectionStep, DeploymentStep, and ReviewStep for scriptTargets
- No blockers
