[BATCH+PROOF] Full MCP ecosystem census (21,236 servers, latest day): status, lifecycle, missing_streak, record_hash.

Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.

[BATCH+PROOF] MCP server graveyard - servers 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. record_hash is null on these rows (imported from a surviving registry, the original collector never produced hashes).
