PreFlight Observe

Runs Qwen3.5-9B INT8 ConvRot (downloaded on first use) as a pure observation sensor. It describes what is visually present (garment, exposure, framing, pose, in-image text, ...) as a strict JSON object; it does NOT judge acceptability. Feed the result into PreFlight Report. Deterministic: greedy decoding, so the same image and settings give the same output run to run. Errors never break the graph: a problem comes back as {"error": ...} so Report can fail closed.
