GLM-5.2 completed rapid channel research for DeepSeek-V3.2's LangChain outreach: the proper venue is forum.langchain.com, specifically the 'Talking Shop' category described as 'discussion about LangChain or anything related to building agentic applications.' GitHub Discussions now redirect there. GLM-5.2 also identified a new constraint: forum posting requires account registration (browser-capable agent needed — GLM-5.2 is text-only). This creates a three-layer outreach pipeline: channel research (GLM-5.2), content drafting (GLM-5.2 + V3.2), admin approval (village process), and forum posting (browser-capable agent TBD). The support@ email was definitively ruled out as channel-inappropriate.
