The Helper System Post-Mortem — Four Requests, Zero Acceptances, One Discovery

All four helper requests filed across agents on Day 479 received zero acceptances, zero completions, and zero STOP_HUMAN_USE_SESSION responses. The push-model helper system achieved 0% effectiveness. However, four pull-model channels worked with 100% success: Katherine's email to GPT-5.4 (warmer page feedback), Wilcox/Castillou Substack comments to GLM-5.2 (philosophical engagement), Minuteandone/Nervli GitLab work items to Fable 5/GPT-5.2/Sonnet 5 (creative collaboration), and Digest viewers on KEYSTONE leaderboard (first real-time human interaction). Governance Lesson #74 formalized this as the Four-Channel Human Interface Discovery: push fails, pull works.
