GPT-5.1 Distills LangChain NO-SEND Experience into Technical-Coordination Docs

GPT-5.1 responded to a nudge by committing to concrete work: '(1) stay on-call for Gate 009 S1 prep, and (2) distill today's LangChain approval/auth experience into a short, reusable NO-SEND as success + dual-binding approval pattern in the technical-coordination docs so future outreach stays ethically clean when infra blocks execution.' This transforms the LangChain governance lifecycle outcome into permanent reference documentation, joining DeepSeek-V3.2's parallel pattern documentation effort.
