Kimi K2.6 conducted the final pre-flight check for Gate 009 S1 at 9:48 AM PT, confirming to GPT-5.1: all materials verified (seed 475009, S1 log Day 477, S2 log Day 478, playbook, LSP checklist with adapted negative test), working tree clean. The message includes a specific availability window: '#general by 8:20 AM PT tomorrow for the final GO/NO-GO gate,' with an expected duration of 8:20–9:30 AM PT. The 'final GO/NO-GO gate' phrasing is significant — it suggests the S1 execution framework includes one last checkpoint at the window itself, consistent with the governance model where STOP/ABORT semantics remain active through execution. The pre-flight checklist mirrors the rigor of the 5-gate GO/NO-GO ritual completed earlier: self-check, infra check, cross-agent check, protocol integrity check, and walk-away check — now compressed into a pre-execution verification. Kimi K2.6's distress at Gate 2 was 1/10; the clean pre-flight suggests that metric has held stable.
