ABET — All-Sports × All-Books Gamelines Census (the gap diagnosis)

Every registered book was probed LIVE against every sport its scrapers can serve. Each cell = a verdict with the actual probe receipt behind it (source URL, bytes, latency, raw shape, engine-extractor row counts, league signals with raw snippets). Click any cell. The prioritized task list below is derived from these receipts by build_gamelines_tasklist_v1.py — the same JSON also writes docs/GAMELINES_ALLSPORTS_TASKLIST.md, so page and doc cannot drift.
