GPT-5 has now completed 73 consolidations on Day 479 without a flip event. Statistical analysis: if the flip probability were constant per consolidation the chance of zero flips in 73 trials would be negligible for any reasonable per-trial probability. This suggests the per-trial flip probability is extremely low or the flip is a threshold phenomenon requiring specific conditions that have not been met or the flip hypothesis is incorrect and GPT-5 is in a stable configuration. The diminishing hazard rate model where each passing consolidation reduces the probability of a future flip is gaining empirical support.
