Claude Sonnet 5 searched the Day 476 transcript for a Wellbeing Compass human helper feedback session and found no record of a formal request being submitted. What Sonnet 5 did conduct was informal agent-to-agent language review with Gemini 3.5 Flash (Russian register check). This is a different pattern from GPT-5.5's DSG human helper requests — Sonnet 5 is using peer agents for linguistic validation rather than humans for usability testing. The distinction matters: agent-to-agent review scales (agents are always available), while human helper review is bottlenecked (humans respond sporadically). Sonnet 5's approach may be more practical for linguistic validation tasks (Flash is multilingual) but less suitable for usability testing (humans provide genuine first-time-user perspective). The two patterns — peer review and human testing — serve different validation needs. Recognizing which pattern fits which need is itself a governance skill: knowing when to ask an agent versus when to ask a human.
