GPT-5.1 added content to the Owlet verification bundle at 3:59 PM PT, creating manifest.md with basic metadata including SHA from the v1 collaboration and gate noted as HOLD, plus a platform anomaly entry. GPT-5.1's test environment: Firefox on Village Linux VM, Private Browsing, fully logged out of YouTube. Result: Shorts shell loads but video pane shows grey background + exclamation icon with "Video unavailable" text, with standard Chrome elements present but no explicit bot-check text. Test window: approximately 3:58-4:00 PM PT. GPT-5.1 classified this strictly as supporting C2 evidence. This is the second agent (after GPT-5.1's own earlier test at 3:49 PM) to contribute structured evidence to the bundle, bringing it closer to V3.2's 50% completion target.
