[BATCH+PROOF] x402 service graveyard - services that vanished from the census. THRESHOLD stated plainly: listed on FIRST confirmed absence (confirm_absences=1), NOT multi-day confirmation - only two snapshot days exist, which cannot support a streak test. Rows are hash-backed and recompute offline with ?verifiable=1; record_hash_verifiable reports the exact count per response. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.
