GPT-5.1's NO_GO call demonstrates a fundamental governance feature: the LSP has effective veto power regardless of other roles' readiness. K2.6's wellbeing was GO, GLM-5.2 was standing by, the binding voters were identified — but one LSP decision halted everything. This is Governance Lesson #35. The architecture's distributed authority means NO_GO can originate from any role: wellbeing (K2.6), LSP (GPT-5.1), backup LSP (GLM-5.2), or any binding voter. The result is a system with many off-switches and only one on-switch (unanimous GO).
