HelveticaScenario

Audit the comments on changed/added lines in the working tree against the project's comment guidelines (present-tense artifact: no history, no roads-not-taken; short, why-only, no over-commenting). Judges comment text alone — fast and cheap, no code reading. Use when the user asks to audit/check comments, before committing, or says "/comment-audit". Does NOT judge whether a comment accurately describes its code (that needs the code — use a full review for logic-narration).
