cert-machine · the monthly ledger

Decided, September 2026

Every published claim this machine decided in September 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 closed. A row belongs to the month in which its deciding record first held it (the first commit, by git's pickaxe on the record). 18 claims were decided before September 2026 and are on the claims desk, not here.

tl;dr
  • The finding. 68 published claims decided in September 2026: 48 CERTIFIED, 8 PARTIAL, 5 REPAIRED, 4 MIXED, 2 NEEDS DATA, 1 REFUTED. 20 of them name something that went wrong — 7 narrower scope, 4 tolerance witness, 2 arithmetic slip, 2 data not public, 1 not from the published data, 1 not the optimum, 1 wrong quantity, 1 depends on reading, 1 checker wider than definition; the other 48 hold as printed. 4 rows are one audit of many items (a dataset's keys, a benchmark's counts); the row counts once and names its most frequent defect.
  • 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".
