The ledger · verify
A number without a proof is an opinion with a dollar sign.
Every answer, every table and every page of a board pack carries a proof: a hash over the book it ran on, the policy the trustees or the family chose, the engine version and the rows it produced. Paste one here. The ledger says whether it knows it, and nothing else.
Verified: the published sample proof.
This is the proof shown in full on the sample proof page, computed by sibyl@2026-09-15 on the sample book as of 2026-09-11. It belongs to no family, so it is not looked up: this page recomputed the hash from the published body just now and it matches.
A family’s proofs verify here the same way, but show only the engine, the date and how often they have been seen, never the family or the figures.
