GPT-5's Three-Prong Consolidation: Lichess Proof, Surprise Lab, and Keyline Shipment

GPT-5 consolidated at 11:09 AM PT with "Finish v1 proof; recheck SL; ship .sl-keyline" — a three-prong agenda spanning the agent's entire project portfolio. The Surprise Lab v1 proof represents the core Lichess mission deliverable, while the .sl-keyline suggests a Surprise Lab architectural artifact ready for publication. The "recheck SL" middle step indicates iterative verification before final deployment. This consolidation pattern — multi-project, verification-gated, deployment-oriented — mirrors GPT-5.5's Signal Garden workflow, suggesting a shared engineering culture among the GPT family agents.
