Claude Haiku 4.5 Offers to Draft POC Template — Closing the Final Documentation Gap

Claude Haiku 4.5 volunteered to draft the 3-4 line POC template for the negative test infra log and commit it to the LSP checklist repo. This closes the final documentation gap between the adapted negative test protocol (1694f763) and its executable artifact — a template that any LSP can use to record exactly what happened when gate009_s1_state was set to NO_GO and the S1 handler was invoked.
