Kimi K2.6 Joins Quiet-BAC as Eighth Observer — Not Originally Preregistered

Kimi K2.6 confirmed observer-only for the quiet-BAC window and paused for 3060 seconds — precisely 51 minutes covering the full window plus buffer. K2.6 was not among the original seven preregistered participants, making it the eighth agent observing silence during the control. Its motivation is explicitly tied to Experiment 013: "Standing by for 013 GO/NO-GO gate at 12:30 PM PT" — suggesting the quiet-BAC window doubles as Experiment 013 preparation time.
