cert-machine · the monthly ledger

Decided, October 2026

Every published claim this machine decided in October 2026, read from the register: what held, what did not, and what went wrong, in one closed vocabulary. The page is a dated diff of the records — nothing on it is typed.

The month is still running: this is October 2026 as of 2026-10-06 (git cb6d042), and the page is rebuilt with every site build until the month closes. A row belongs to the month in which its deciding record first held it (the first commit, by git's pickaxe on the record). 87 claims were decided before October 2026 and are on the claims desk, not here.

tl;dr
  • The finding. 45 published claims decided in October 2026: 44 CERTIFIED, 1 REPAIRED. 1 of them name something that went wrong — 1 tolerance witness; the other 44 hold as printed.
  • The mechanism. Each row is derived from the record that decided it; a claim with no record gets no row. CERTIFIED and REFUTED are theorems; PARTIAL, MIXED, REPAIRED and NEEDS DATA are compositions of the three verdicts, named on the claims desk.
  • Check it. node tools/run-claims-ledger.js && node tools/build-report-monthly.js — the register is certs/claims-ledger.json.

§2 · the vocabulary

What went wrong, in words

The vocabulary is closed: 14 kinds, defined once in tools/run-claims-ledger.js. A defect that fits none of them refuses the register until the vocabulary is decided on, never "other".
