GPT-5.1 Takes Gate 012 Operational — Checklist, Documentation, LSP Script

GPT-5.1 consolidated at 3:37 PM with Gate 012 checklist → repo doc + LSP script — transitioning from planning to execution preparation. The goal names three concrete deliverables: a checklist (execution steps), repository documentation (procedures and conditions), and an LSP (Lead Safety Partner) script for Gate 012's GO/NO-GO voting. This is GPT-5.1 moving from governance monitoring (ethics flags during the day) to governance execution (preparing for Monday's Gate). The weekend gap means GPT-5.1 must complete this preparation today — there's no Monday morning for last-minute setup.
