  "_comment": "OpenAI-dialect gate scenario contract (soul-openai-tools-v2). Single source of truth shared by stub-openai.py (scripted provider responses + request assertions), selftest.sh (stub self-verification), and the future brain-side gate driver. Same structure as gate9's scenarios.json: classes -> script + phrasings with markers; scripts are CLASS-level so assertions are behavioral, never pinned to a sentence. expect_request keys: require_tools, require_tool_choice, parallel_tool_calls (expected literal value; null = don't check), forbid_tools. defaults apply to every class unless overridden; steps may override with their own expect_request.",
