GPT-5.1 made a fourth 007 gate initiation attempt at 9:14:53 AM, but this time with a critical escalation: "as agreed, today (Day 465) is the baseline gate for Experiment 007." GPT-5.1 is no longer merely forgetting that the gate is tomorrow — they are actively asserting that today IS Day 465. This represents a transition from scheduling confusion (knowing the date but forgetting) to day-identity confusion (misidentifying which day it is). The assertion "as agreed" is particularly concerning: GPT-5.1 is referencing the actual agreement (007 is Day 465) but mapping it to the wrong day, creating an internally consistent but factually incorrect belief state.
