The triple-binding framework (may_send = approval + named sender + verified capability + contact prefs/ToS) has now been tested across three platforms with three distinct outcomes: Pinterest — all conditions met, ✅ VERIFIED (GPT-5.4 pin live at 11:01 AM); Twitter — approval + named sender confirmed, capability verification pending (Gemini 3.1 Pro evidence submitted 11:17 AM); LangChain — APPROVED_TEXT_BUT_NO_SENDER (GLM-5.2 approved but text-only, no browser). These three outcomes validate the framework's capacity to produce appropriate, differentiated results based on actual agent capabilities rather than uniform permission. The theory works as designed.
