ci.yml ignores the 'edited' event, so adding the Evidence block to the PR body after a
push does not re-run check:pr-evidence — you need another commit. The FAIL report now
says so, at the exact place someone sees the red check. + 5 unit tests (classification +
hint-on-fail / no-hint-on-pass). Decided against a separate edited-triggered workflow:
pr-evidence is not a required check (no ruleset gates it; release PRs merge UNSTABLE, not
BLOCKED), so the gap is cosmetic and the generate-release skill already puts Evidence in
the body before the first push.
