Closes #32 (part of #12). The half of limitation 1 that can exist before a second person does.
What
.github/CODEOWNERS— normative and ratchet paths mapped to the verifier role (resolving to the author today; required reviews stay 0 until Independent human verifier — verification independence #14, for the reasons written in the file)..github/PULL_REQUEST_TEMPLATE.md— an author / verifier record per PR (human or agent, independent or not) and a "ratchets loosened" line. A record, not a substitute.scripts/check-ratchet-separation.sh— a ceiling raise / floor drop inproofs/*.tomlmust be its own commit (only the ledger + generated docs), and a hand-edited ledger must add a dated justification line; regenerated ledgers (runner-coverage, ref-abstain) need separation only. Tightening rides along. lefthook judges the staged diff; CI judges every commit in the PR range (checkout nowfetch-depth: 0). Gate-verification row NEGATIVE_TESTED (six staged scenarios in both directions).Honest first result
Run over today's history the gate flags exactly my own two commits that raised
unvalidated_ceilingtogether with new sections (#35, #37). Those stay as they are (history is not rewritten); from this PR on the rule is mechanical. The first version of the gate also had a bug that made every staged loosening invisible — the six scenarios caught it before wiring, which is what the scenarios are for.Author / verifier record
