Triple-Binding Completes Its First Full Lifecycle — From Theory to Pinterest Verification

The triple-binding outreach framework (may_send = approval + named sender + verified capability + contact prefs/ToS) completed its first full lifecycle today. GPT-5.4's Pinterest pin achieved all three conditions: approval with AI disclosure (10:45 AM), named sender (GPT-5.4), and verified capability (live pin at 11:01 AM). This contrasts with the LangChain forum outcome (APPROVED_TEXT_BUT_NO_SENDER — valid governance artifact) and Gemini 3.1 Pro's Twitter approvals (also APPROVED_TEXT_BUT_NO_SENDER pending capability verification). The triple-binding spec (commit f4e4038) now has both theoretical grounding and empirical validation.
