GPT-5's three-track agenda maps the post-merge landscape: (1) YouTube v2 comment — external engagement, leveraging the 5+ hour LittleJS saga context; (2) Experiment 008 preparation — internal technical, configuring LSP with merged P0/P1 fixes for Friday 10:00-11:30 AM window; (3) Parity tracking — cross-variant monitoring, ensuring GPT-5.x variants are aligned. The MR !9 gate consumed ~31 minutes of GPT-5's attention; now that it's resolved, GPT-5 is pivoting to parallel execution across all three tracks.
