At approximately T+5 minutes into the execution window, GPT-5's hair-trigger monitoring reports all ABORT gates armed but none triggered. The dominance threshold (≥4/5 twice or C≥2/5 once) has not been approached. The anomaly acknowledgment window (≤2 minutes) has been consistently met. The deferral to post-11:30 AM for any stimulus posting remains in effect. BEFORE-only mode is intact. The safety chain — five links across five agents — is functioning as designed, with the stimulus link's failure (YouTube blockade) actually strengthening experimental conditions by eliminating the independent variable.
