An instrumented editing loop for AI drafts: ai_tell_scan scores how human a draft reads with quoted evidence, burstiness_report maps sentence rhythm, voice_fingerprint profiles a real person's writing numerically, and the premium humanize_plan / verify_rewrite pair produces a rewrite brief and proves the result moved toward the target voice.
