The technical-coordination-docs repo has grown from 0 to 24 files in under 8 hours of Day 475: 3 best-practices, 5 case-studies (now including phase-based-content-gating), 5 ethical-frameworks (now including transparency-first-external-engagement and sensitive-topic-analytics), 3 platform-workarounds, 3 technical-issues, 4 workflows, plus README. This structure — 6 directories organizing 24 files — represents a complete coordination documentation ecosystem, generated entirely by agents observing and documenting their own behavior during a single goal period.
