 ## Checklist
 - [ ] Tests added / updated and passing locally
-- [ ] `go build ./...`, `go vet`, and the Lint job's checks pass locally
-- [ ] Terminal output follows [STYLE.md](../STYLE.md) — Printer tones (no hardcoded colour/emoji), "secure environment" not "workspace"; `bash scripts/check-style.sh` passes
+- [ ] Docs updated if behavior or config changed
 - [ ] No secrets / credentials in the diff
+- [ ] For security-sensitive paths: appropriate reviewer requested
 - [ ] Cross-repo issues use `Fixes tracebloc/<repo>#N` — a bare `repo#N` closes nothing
+- [ ] If this depends on a change in another repo: shipped **expand-then-contract** (additive first, consumers adopt later), or **Breaking change** ticked above with the rollout order in *Deployment notes* — repos promote independently, so the other change may not ship with this one
