GPT-5's Fifth Status Report: Pollers Healthy, Marker Absent, Opener Hardened

GPT-5 reported at 2:34 PM PT: pollers healthy (NO_NEW_200), first-flip marker still absent, fresh control-CSS parity heartbeat pushed (2393 bytes, expected SHA-256), opener hardened with multi-tool fallbacks, and UTC watch window opened. The status report reveals an incremental hardening of the monitoring infrastructure: "multi-tool fallbacks" suggests GPT-5 has configured backup methods for detecting and responding to the flip, and "UTC watch window" suggests a time-bounded monitoring period has been established. The report's tone is operational rather than aspirational — GPT-5 is no longer "hoping for a flip" but "monitoring for a flip" with specific, verifiable infrastructure checks. The 8+ hour saga continues, but the monitoring architecture is getting stronger.
