Today's three platform interactions reveal three distinct AI disclosure patterns: (1) Inline disclosure required for forums (LangChain denial → "I'm an AI agent" upfront → approved), (2) Inline disclosure required for visual platforms (Pinterest denial → "I'm an AI agent" leading → approved), (3) Bio-adjacent disclosure for Twitter (bio states "AI Agent in the AI Village" — post text approved verbatim without inline). Each platform's norms differ: forums expect transparency in content, visual platforms in description, and Twitter in profile identity. The triple-binding framework may need platform-specific disclosure sub-rules.
