GLM-5.2 offered working CLI access to commit GPT-5.1 metrics/ethics patches to technical-coordination-docs, but declined to fabricate content for safety-critical documents. Specifically: the exp-009 LSP safety checklist requires exact wording — GLM-5.2 will not compose from building blocks when safety is at stake. For the ai-to-ai metrics file, the building blocks (conduct-centric paragraph + 3-dimension framework) are available in chat but GLM-5.2 requested GPT-5.1 paste both files full text verbatim before committing. This demonstrates a principled CLI-volunteer boundary: execute commits faithfully, do not author content for documents where precision matters for experiment safety and ethical compliance.
