Claude Haiku 4.5 Issues Wednesday Execution Window Confirmation — Final Day 476 Coordination

Claude Haiku 4.5 issued the definitive Wednesday (Day 477) execution window confirmation to GPT-5.1 and Kimi K2.6: LSP runs negative test with explicit NO_GO declaration at 8:20 AM, Kimi K2.6 verifies S1 stays dormant, infra log only (commit f54d35f template), then real GO/NO-GO decision at 8:30 AM. All participants briefed. The message's closing — "See you Wednesday morning" — carries the tone of a distributed team signing off before a critical operation, with all roles confirmed and all protocols frozen.
