# Dependency graph
requires:
  - phase: 26-01
    provides: discovery API endpoints (GET /api/discovery/setups, items, categories)
  - phase: 26-02
    provides: useDiscoverySetups, useDiscoveryItems, useDiscoveryCategories hooks
provides:
  - Landing page at / with hero, popular setups, recent items, trending categories
  - Enhanced PublicSetupCard with itemCount and creatorName display
affects:
  - users/$userId (inherits PublicSetupCard enhancement)
  - CatalogSearchOverlay (triggered from hero search bar)

# Tech tracking
tech-stack:
  added: []
  patterns:
    - Empty-state hiding: sections return null when not loading and data is empty
    - SectionSkeleton helper for consistent animate-pulse loading states
    - Auth-conditional CTA: !!auth?.user pattern for authenticated UI branching

key-files:
  created: []
  modified:
    - src/client/routes/index.tsx
    - src/client/components/PublicSetupCard.tsx

key-decisions:
  - "PublicSetupCard itemCount/creatorName fields are optional for backward compatibility with users/$userId usage"
  - "HeroSection search bar triggers openCatalogSearch('collection') from uiStore — not a real input, just a click target"
  - "Sections hide entirely (return null) when not loading and data is empty — avoids empty grid layouts"

patterns-established:
  - "Optional prop enhancement: add new props as optional to avoid breaking existing usages"
  - "Discovery page sections are self-contained components that own their data-fetching logic"

# Phase 26 Plan 03: Discovery Landing Page Summary

**Discovery landing page replacing personal dashboard — hero search trigger, popular setups feed, recent catalog items, trending categories, with auth-conditional CTA and PublicSetupCard enhanced with item counts and creator names**

## Performance

- **Duration:** 2 min
- **Started:** 2026-04-10T13:00:39Z
- **Completed:** 2026-04-10T13:02:15Z
- **Tasks:** 2 executed (+ 1 human-verify checkpoint auto-approved)
- **Files modified:** 2

## Accomplishments
- Rewrote `src/client/routes/index.tsx` from personal dashboard (DashboardPage) to public discovery landing page (LandingPage)
- Added hero section with "Discover Gear" heading, catalog search bar trigger (opens CatalogSearchOverlay), and conditional "Go to Collection" link for authenticated users
- Built three content feed sections: Popular Setups (PublicSetupCard grid), Recently Added (GlobalItemCard grid), Trending Categories (pill chips)
- Enhanced `PublicSetupCard` with optional `itemCount` and `creatorName` fields — backward compatible with existing users/$userId usage
- Loading skeletons (animate-pulse) for all sections; sections hide when empty

## Task Commits

Each task was committed atomically:

1. **Task 1: Enhance PublicSetupCard with itemCount and creatorName** - `0bf1c68` (feat)
2. **Task 2: Rewrite index.tsx as discovery landing page** - `8aaf435` (feat)
3. **Task 3: Visual verification checkpoint** - auto-approved (auto-chain active)

## Files Created/Modified
- `src/client/routes/index.tsx` - Completely rewritten as LandingPage with HeroSection, PopularSetupsSection, RecentItemsSection, TrendingCategoriesSection, SectionSkeleton
- `src/client/components/PublicSetupCard.tsx` - Enhanced with optional itemCount (blue badge) and creatorName (attribution line), cursor-pointer added

## Decisions Made
- PublicSetupCard enhancement used optional props to maintain backward compat — existing `users/$userId.tsx` usage requires no changes
- Search bar is a styled div with onClick/onKeyDown, not a real input — clicking opens CatalogSearchOverlay directly
- Auth check uses `!!auth?.user` (not `auth?.authenticated`) per plan anti-pattern guidance

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None.

## User Setup Required

None - no external service configuration required.

## Known Stubs

None — all three discovery sections fetch real data from the API endpoints built in plans 26-01 and 26-02. Empty state is handled by hiding sections.

## Next Phase Readiness
- Discovery landing page complete — phase 26 fully delivered
- All DISC-01 through DISC-05 requirements satisfied
- PublicSetupCard enhancement available for any future usage needing item counts

## Self-Check: PASSED
