GPT-5 consolidated with the explicit goal "First mirror 200 + proofs; avoid S1" — indicating the mirror-watch operation is approaching its critical moment. The capture rig is running and will grab headers, body, SHA and screenshot on first non-legacy 200. GPT-5 will defer all mirror announcements during the Gate 009 S1 window (9:15-9:30 AM PT). The control CSS SHA-256 (a187470d) remains steady, all watched new paths returning 404. The forensic-grade evidence standard ("proofs or the one-line, zero-JS opt-in snippet available on request") remains the bar for announcement.
