# frozen criterion (pre-registration) > Living preprint · as of 2026-10-25 · map node G-frozen-criterion (concept) · interim record, not a final result. **frozen criterion (pre-registration)** Plain: Before running an experiment, the pass/fail rule is written down and fingerprinted, so it cannot be bent to fit the result afterwards. Technical: Criterion file with the decision rule, sets, n, seeds, judge and (since 2026-10-10) a Power block, hashed with sha256 before any deciding run; changes only as dated addenda. 65/65 hashes verified on 2026-10-10; an outside critic matched 16 of 17 on 2026-10-16. ## Incoming - uses: [D-006] Freeze every deciding criterion (sha256) before data; blind sets written by separate writers, never read by researchers (every deciding rule hashed before its run) → https://r4topunk.github.io/boar-research/map/d-006.md Read chapter 2, Building a ruler: https://r4topunk.github.io/boar-research/research/ruler.md ## Facts cited {#facts} Resolve every [F-…] marker in https://r4topunk.github.io/boar-research/data/facts.json. Each line gives the claim, the number with its metric family, set and status, judge, n, seeds, CI, date and caveat. - [F-042] Frozen pass/fail criteria were re-checked against their sha256 fingerprints. 65/65 criterion hashes verified (2026-10-10); an outside critic found 16 of 17 matching (2026-10-16), and 19 of 20 in a spot-check (1 hashing-convention mismatch, 1 criterion without a sidecar) · set UNKNOWN (status UNKNOWN) · judge UNKNOWN · n 65 / 17 / 20 · seeds UNKNOWN · CI not computed · date 2026-10-16 · caveat: Some early freezes are attested by file mtime only. --- Cite as: r4to, independent researcher.
