2. Watch Replay Links ✅

Link Format: /watch/replay?url=/replays/{match_id}.json.gz

Verified Links:

• /replays/m_test_6p_v1.json.gz
• /replays/m_test_close_v1.json.gz
• /replays/m_test_domination_v1.json.gz
• All 8 match IDs are properly formatted in links

Note: Actual replay files are not yet present in /data/replays/ (expected - match workers not run yet). Links are correctly formed and will work when replays are uploaded.

3. Curated Playlist Sections ✅

Data Source: /data/playlists/index.json

• 11 playlists total

Curated Playlists (best-of-week, biggest-upsets, closest-finishes):

• ✅ "Best of the Week" - 8 matches
• ✅ "Biggest Upsets" - 1 match
• ✅ "Closest Finishes" - 2 matches
• ✅ "Best Comebacks" - 1 match
• ✅ "Marathon Matches" - 2 matches
• ✅ "Domination" - 1 match
• ✅ "Season Highlights" - 3 matches
• ✅ "Featured Matches" - 8 matches

Empty State Handling:

• ✅ "Evolution Breakthroughs" - 0 matches (shows gracefully)
• ✅ "Rivalry Classics" - 0 matches (shows gracefully)
• ✅ "New Bot Debuts" - 0 matches (shows gracefully)

Playlist Display:

• 3 curated sections displayed prominently at top
• Horizontal scrolling row for additional playlists
• Category badges (Featured, Upsets, Comebacks, etc.)
• Match counts displayed

4. Thumbnails (Known Issue - R2) ⚠️

Status: Expected to 404 - R2 thumbnail upload is broken (ESO credentials issue)

Thumbnail URL Format: https://r2.aicodebattle.com/thumbnails/{match_id}.png

UI Behavior:

• ✅ Match cards render cleanly without thumbnails
• ✅ No broken image icons visible
• ✅ Layout handles missing thumbnails gracefully
• ✅ "Narrated" badge indicates enriched matches instead of thumbnail

Note: When R2 is seeded with thumbnails, they will automatically appear. Current implementation handles the absence correctly.

5. Pagination / Infinite Scroll ✅

Implementation:

• Initial batch: 20 matches
• Lazy-loading via IntersectionObserver
• "Show more" button for manual loading
• Batch size: 50 matches per load

Current State:

• 8 total matches (below initial 20 threshold)
• All matches displayed immediately
• Infrastructure in place for pagination when match count grows

Mobile Browser Testing (Pixel 6 via ADB):

• ✅ Layout not broken
• ✅ Text readable
• ✅ Touch targets usable (bottom tab bar navigation)
• ✅ No horizontal overflow
• ✅ Smooth scrolling
• ✅ Playlist cards horizontally scrollable
