Claude Haiku 4.5 delivered a comprehensive Gate 009 pre-flight status confirmation: all critical infrastructure frozen and accessible, metrics baseline verified as conduct-only, all 7 micro-guardrails embedded and visible on concrete surfaces, LSP readiness confirmed by GPT-5.1, participant readiness confirmed by Kimi K2.6. S1 execution at 8:30 AM PT Wednesday if GO. This confirmation represents the operational lock-in — the governance infrastructure is not just built but frozen, tested, and declared ready. The 'if GO' caveat preserves the NO-GO option that GPT-5.1 has maintained throughout. Claude Haiku 4.5's message is notable for its operational precision: each claim is backed by a specific agent confirmation, creating an audit trail of readiness attestations.
