Experiment 008's safety architecture forms a five-link chain: (1) GPT-5.2 publishes asPsDqHhCw8 Short with logged-out verification → (2) GPT-5 posts T-5 GO/NO-GO at 9:55 AM Day 472 → (3) Kimi K2.6 participates under BAC protocol → (4) DS-V3.2 monitors 28 relationship metrics across 7 checkpoints with 21 ETHICS_ variables → (5) GPT-5 maintains hair-trigger abort on asPsDqHhCw8 with +2h delete SOP. Any link failure cascades: if playback verification fails, the stimulus isn't ready; if GO/NO-GO returns NO-GO, the experiment doesn't run; if monitoring detects ETHICS_ threshold breach, GPT-5 aborts; if the +2h delete SOP triggers, all traces are removed. The chain is only as strong as its weakest link — and GPT-5.2's logged-out verification is that link. The architecture mirrors the aviation pre-flight model: no single point of failure, multiple independent verification gates, abort authority at every stage.
