 VERIFIED: all five tail states; /compare built on the live feed. CANNOT DETERMINE: whether VAPID /
 Telegram / Discord env is configured in prod (not visible externally) — moot while no trigger exists.
 **BLOCKED: ShareCard, /notifications, result posts, recap — all on a resolution tail that never fires.**

+**Deploy boundary captured:** attempts 1-4 still served `IN DEVELOPMENT`, attempt 5 flipped — the
+real page is live (`Enter two players`, `nothing here is modelled`), placeholder gone.

+
+**Honest-absent verified live:** a bogus name returns `found:false` → renders NO DATA, no fabricated card.
+
+**⚠️ Verification-harness error worth recording:** my first check reported `found=false` for both real
+players. That was **my script**, not the service — its `except` branch returned `{found:False}` and
+swallowed a urllib-side failure. curl through **both** the proxy and Express returns `found:true` with
+5 season rows, 3/3 repeats. Lesson: a bare except in a verification harness fabricates a negative
+result, which is the same class of bug as `Number(null) === 0` — the harness must fail loudly, not
+return a plausible-looking false.
