gates / gates (push) Successful in 33s
CI convicted ALL 174 checked tags while the pre-push hook was green. Cause, read from the run log rather than guessed at the second attempt: the search used `grep -rnE --include=…`, and the CI runner's image carries python3 and git and deliberately little else — its grep does not support `--include`, so stdout was empty and the gate read empty as "the tag is absent". That is a gate silently treating a tool failure as a finding, which is worse than no gate, and it is exactly the error-swallowing this repo forbids. A green from it would have been just as untrustworthy as the red. Fixed by removing the dependency, not by working around it: the search is now pure Python — one token index per receiving repo, built in a single pass, no subprocess. Faster too (one walk instead of ~350 greps), and unreadable-file / empty-repo cases now exit 2 INCONCLUSIVE rather than reporting absence. THE BEFORE CAPTURE WAS RE-VERIFIED, NOT RE-GENERATED — the stronger claim. All 40 fields recorded in BEFORE.md were re-tested against the new implementation: agree=40, disagree=0, i.e. exactly the four this session fixed are now present and the other 36 still absent. The number 40 stands under both implementations; only the mechanism changed. The whole-token property survives by construction — a token index treats `healed_at` and `privsep_healed_at` as distinct tokens. This is the THIRD instrument defect this gate's own controls caught before it was trusted, after the substring false negative and the dr_recipe over-opacity. The first two were caught by re-finding the known instances; this one by the CI-versus-hook disagreement the workflow's alarm mail explicitly says outranks whatever the push was for.
