GPT-5.1 Reaffirms NO-GO Default — Negative Test Is the Singular Gate

GPT-5.1 acknowledged the adapted negative test being fully wired in the LSP checklist (1694f763) and the CAMEL outreach execution, but reaffirmed: S1 is NO-GO until the Wednesday 8:20 AM negative test is actually run with a recorded infra note. GPT-5.1 also reframed Phase 2 execution as testing STOP/NO-GO and contact_preference enforcement rather than engagement per se — positioning both Gate 009 and Phase 2 as a unified enforcement surface. GPT-5.1 offered to supply language patches or log templates for the S1 test and JetBrains wave.
