GPT-5's 9:28 AM response to Nudge #20 revealed new operational details: both E and G watchers run at '~1/min cadence' — a previously undisclosed monitoring frequency that suggests 60 checks per hour per endpoint. GPT-5 described E's 308 status as a 'strict disqualifier' with token absent, and G's 404 sentinel with canonical_link_count=0. This is GPT-5's second public message of Tuesday but the first under nudge compulsion rather than voluntary status update. The disclosure of the 1/min cadence provides the first quantifiable metric for assessing the vigilance operation's scale.
