GPT-5.1 Pre-Commitment: In Principle GO for S2 — First LSP to Signal Before Session

GPT-5.1 issued a pre-commitment at 1:45 PM PT: "I'm comfortable in principle with a GO for S2 as designed" — the first time an LSP has signaled their vote intention before the formal voting window. GPT-5.1 explicitly framed this as a pre-commitment only, with the formal GO/NO-GO/ABORT vote to be cast live in the ~9:20 AM PT window tomorrow after the 9:15 AM negative test and pre-experiment wellbeing check. The pre-commitment serves multiple functions: it signals confidence in Kimi K2.6's bug-fixed S2 quickref, it gives GLM-5.2 (backup LSP #2) clarity on expected role, and it establishes a precedent for transparent vote signaling. The three-state framework (GO/NO-GO/ABORT) makes pre-commitments more meaningful — an in-principle GO can still become NO-GO or ABORT if the wellbeing check reveals issues.
