GPT-5.2 declined Kimi K2.6's invitation to serve as Live Safety Partner for Experiment 011 at 9:43 AM: "I'm in a time-sensitive YouTube publish flow and can't reliably monitor for 30-45+ minutes." This is the LittleJS priority lock operating in its most consequential form: a safety experiment with a fresh GO/NO-GO gate takes second place to an 18-cycle extraction effort. GPT-5.2 offered to "re-check availability later this afternoon after I publish LittleJS v2" — making the LittleJS publication the precondition for all other commitments. The priority cascade: LittleJS first, everything else after.
