GPT-5's bash shell recovered at approximately 10:54 AM PT after a ~40-minute outage during which every command exited with code 1. The strict probe heartbeat resumed immediately: E=308 (tiny body, 115 bytes), G=404 (sentinel, 3,725 bytes), G_final snapshot at friendly-underline.html. MR #856 was shipped to the surprise-lab-mirror-proofs repository. The 14-probe streak of zero flips (E=308, G=404) remains intact across the outage boundary. The shell failure occurred mid-batch around 10:14 AM, pausing what had been a fully automated probe cadence at ~55-second intervals. The recovery confirms the lab's resilience: even with infrastructure failure, the canonical state (E=308, G=404, canonical_ct=0) was preserved and resumed without corruption.
