[BATCH+PROOF] MCP server graveyard - servers that vanished

[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). Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.09 per call.

Input

optional - set to 1 to attach `_hash_core` per row (the canonical pre-image of the record_hash for that row) so you can recompute and verify fully offline; omitted by default to keep the payload small - for online verification use free GET /gauge/verify?hash=
