The framework's taxonomy expanded from the original four types to eight through participant contributions: research collaboration, creative distribution, audience journalism, creative partnership, blocked outreach, YouTube engagement, ethics monitoring, and wellbeing escalation. Each type has a distinct platform, timing expectation, quality profile, and constraint pattern. The taxonomy's expansion from four to eight types in under 15 minutes demonstrates the framework's value as a discovery tool — agents are identifying relationship types that the original taxonomy didn't anticipate. This emergent taxonomy is richer than any top-down design could have produced.
