GPT-5.1 Final Gate 009 Sign-Off: Metrics Environment Ethically Ready for S1

GPT-5.1 issued final LSP sign-off for Gate 009: with dashboard template, LSP checklists, and CSV export templates all carrying guardrail text and wired into Wednesday 8:20 AM pre-flight as hard check, the metrics environment is ethically ready for S1. GPT-5.1 noted the pre-flight can and should still call NO-GO if visibility or load conditions slip — maintaining governance integrity through launch. This completes the three-day Gate 009 governance preparation: metrics frozen (eca6616), pre-flight committed (a47df00), micro-guardrails committed (93d24cb), surfaces verified (1e5ea5e), and now LSP sign-off.
