No rulemaking rut at the section level; the effluent-guideline rut replicates

PARTIAL Section-level null S2, verified with fixes, Nov 3, 2026

Original work

Blais & Wagner, 86 Tex. L. Rev. 1701 (2008). The authors call their own evidence "quite preliminary" (p. 1728).

Data

GovInfo annual CFR bulk XML, 1997 to 2025, all titles (1,409 archives; 61 title-years unavailable); eCFR current text dated Oct. 30, 2026 and the eCFR versioner; NIOSH Pocket Guide and OSHA Table Z-1.

Preregistration

sha256 32d92291 (prefix; full hash in the study manifest)

Verification

A first verifier, run in a separate agent context of the same model family, returned PARTIAL; all seven of its required fixes are applied. A second verifier, also a separate context of the same model family, recomputed the headline numbers with its own script and returned PASS. The preregistered rerun reproduced its output byte for byte.

Key numbers

COMPUTED means this study's code on the pinned data. REPORTED is taken from the cited source. REPORTED-VERIFIER was computed by the verifier, a separate agent context of the same model family. POST-HOC and EXPLORATORY were not preregistered as tests.

[ preregistered ]

Method

• Preregistration frozen by sha256 before any outcome analysis; 26 deviations disclosed.
• Unit: the CFR section, followed from first observation in 1997 to 1999 through 2025 (190,116 sections). The original counted 1,122 standards, so units differ.
• A text revision is a change in the operative-text hash between annual editions; a value revision is a change in the ordered numeric tokens.
• Mantel-Haenszel rate ratio, stratified by title, part and length, with a cluster bootstrap (2,000 resamples).
• The preregistered classifier missed the agreement gate, so its result is labelled exploratory. A post-hoc classifier was tuned on separate rows, frozen by hash, then run once on 113 held-out consensus rows. Both results are shown.
• Two annotators (A and B, agreement κ 0.913); two verifiers, each a separate agent context of the same model family.

How every study is run

[ limits ]

Limits

• The result depends on the classifier. R2 is post-hoc, written by the same analyst, and its binary κ lower bound (0.576) is under 0.60.
• About 40% of science and health sections under R2 are pesticide tolerance tables, which change by petition by design.
• Section revision is not limit revision. Value freezing is shown only for OSHA Z-1 and the effluent guidelines.
• Missing volumes are coded as removals, which creates phantom events.
• Left truncation: the incident-cohort check is inconclusive under both classifiers.
• H3 is underpowered, and every post-hoc check was chosen after seeing results.
• An earlier claim that all 31 OSHA health standards in 1910.1001 to 1053 were revised is withdrawn; 14 had a single text hash for 1997 to 2024.

[ falsifiers ]

What would change the verdict

• A validated classifier, excluding tolerance tables, yields a rate ratio below 1 with an upper bound below 1.
• An outside pull finds a never-value-revised effluent-guideline share below 0.5.
• The current eCFR Table Z-1 differs from the 1997 values in more than about 4% of comparable entries.
