+  - 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]

+# 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
