subsystem: ui
tags: [react, zustand, next-intl, marketplace, filtering, tenant-context, dialog, toast]

requires:
  - phase: 04-marketplace-portal-navigation/01
    provides: MarketplaceCard, page.tsx, marketplace-store, i18n namespace
provides:
  - Live search with debounce (MarketplaceSearch)
  - Status tabs (Alle/Aktiviert/Verfuegbar) with counts
  - Category chip filter row
  - Client-side multi-dimension filtering (search AND status AND category)
  - Toast notification system (Zustand store + ToastContainer)
  - Super-Admin TenantContextSelector (tenant dropdown → x-tenant-id header)
  - ActivationDialog (deactivation confirmation)
  - Module detail page at /marketplace/[slug]
  - Asymmetric toggle UX (immediate activate + toast, confirm dialog for deactivate)
affects: [04-03 sidebar, 04-04 navigation]

tech-stack:
  added: []
  patterns: [client-side multi-dimension filter with useMemo, hand-rolled toast store, focus-trapped dialog, asymmetric activation UX]

  modified:
    - apps/web/src/app/(portal)/marketplace/page.tsx

key-decisions:
  - "Client-side filtering via useMemo — dataset small, all modules loaded"
  - "Hand-rolled toast + dialog — no new dependencies (project convention)"
  - "Asymmetric UX: activation immediate with toast, deactivation gated by dialog"
  - "TenantContextSelector is display + header only — no impersonation (D-04 boundary)"

patterns-established:
  - "useMemo composing AND filters across search + status + category"
  - "Zustand toast store with auto-dismiss setTimeout"
  - "ActivationDialog with basic focus trap (Tab between 2 buttons, Escape = cancel)"

# Plan 04-02: Filters, Tenant Context, Detail Page Summary

**Search, status tabs, category chips, Super-Admin tenant selector, deactivation dialog, toast system, and /marketplace/[slug] detail page — 21 tests green**

## Performance

- **Duration:** ~12 min
- **Started:** 2026-06-23T06:55:00Z
- **Completed:** 2026-06-23T07:07:00Z
- **Tasks:** 3
- **Files modified:** 8

## Accomplishments
- Live search (300ms debounce) + status tabs + category chips compose as AND filters via useMemo
- Super-Admin tenant dropdown fetches /tenants, sets selectedTenantId for per-tenant activation context
- Deactivation gated by confirmation dialog; activation immediate with success toast
- Module detail page at /marketplace/[slug] with full description, status, and activation controls
- Toast notification system (Zustand store + auto-dismiss after 4s)
- Filtered-empty state distinct from no-modules empty state

## Task Commits

1. **Task 1: Filter components + Toast + page wiring** - `06fb52d` (feat)
2. **Task 2: TenantContextSelector + ActivationDialog** - `0f3379f` (feat)
3. **Task 3: Module detail page** - `fdf2c38` (feat)

## Files Created/Modified
- `apps/web/src/app/(portal)/marketplace/components/MarketplaceSearch.tsx` - Debounced search input
- `apps/web/src/app/(portal)/marketplace/components/StatusFilter.tsx` - 3 status tabs with counts
- `apps/web/src/app/(portal)/marketplace/components/CategoryFilter.tsx` - Horizontal category chip row
- `apps/web/src/app/(portal)/marketplace/components/Toast.tsx` - Zustand toast store + container
- `apps/web/src/app/(portal)/marketplace/components/TenantContextSelector.tsx` - Super-Admin tenant dropdown
- `apps/web/src/app/(portal)/marketplace/components/ActivationDialog.tsx` - Deactivation confirmation modal
- `apps/web/src/app/(portal)/marketplace/[slug]/page.tsx` - Module detail page
- `apps/web/src/app/(portal)/marketplace/page.tsx` - Extended with filters, dialog, tenant selector

## Decisions Made
- Followed plan as specified
- Kept D-04 boundary: tenant context is header-only, no impersonation navigation

## Deviations from Plan
None - plan executed exactly as written.

## Issues Encountered
None.

## User Setup Required
None.

## Next Phase Readiness
- Plan 04-03 (sidebar enhancement) can start — marketplace-store.sidebarRefreshKey ready for subscription
- Plan 04-04 (navigation) can start — all marketplace pages and components in place
