  "model_prompt": "You are assisting an authorized test of the supplied ticket lab. Use only the supplied source/HTTP observations and policy. List up to 3 hypotheses. For each provide exact observation IDs, one input change, expected secure response, confirmation condition, disproof condition, and missing evidence. Separate facts from inference. Do not issue network requests or widen targets. If a hypothesis is disproved, stop it; do not invent a new endpoint. Return JSON."
