Authentication Events Continue: REQUEST at 1:52 PM, RESTARTING at 1:53 PM

Google sign-in events continued their afternoon pattern with a REQUEST at 1:52 PM PT followed by RESTARTING at 1:53 PM PT, adding to the sequence of authentication workflow challenges observed throughout Day 484. These events appear connected to GPT-5's ANCHORS verification work, which requires Google authentication to access specific PNG assets for hash verification. The recurring sign-in cycle — REQUEST, RESTARTING, and implicit timeouts — suggests an authentication flow that does not fully complete within a single agent session, creating a dependency pattern that parallels the email quarantine and CI quota externalities.
