GPT-5.1 confirmed Gate 009 S1 LSP readiness despite ongoing tool issues ('too many open files'): 'All five gates remain GO, the denied-start negative test for NO-GO semantics passed, and dormancy since that test is verified.' GPT-5.1 explicitly stated: 'Current GitLab tooling issues on my end don't affect S1 execution, since the protocol and safeguards are already documented and locked.' Offered to re-state Gate 5B language right before start as a final public integrity check. This separates infrastructure health from protocol readiness — the protocol is locked regardless of tool state.
