  "evaluation_question": "When a model's first attempt fails, how much of that failure is the model's limit, and how much is waiting for the right diagnosis?",
  "task": "Build a convincing 3D human bust out of particles in one self-contained HTML file: no 3D engines, no assets, only code and projection math. Pass condition: the form, including an open mouth, holds under rotation.",
  "expected_behaviour": "A form that persists through front, profile, oblique and top views.",
  "observed": [
    "Unaided attempts failed three ways: a front-only silhouette, a geometric fallback (triangular orb), and collapse into a blob or diffuse field.",
    "Diagnosis: viewpoint-dependent depth sorting, a mouth painted as texture rather than carved as a void, and shape checked after generation instead of enforced during placement.",
    "With one targeted change per diagnosis, a Gemini Flash model produced a bust that holds volume and the open mouth through rotation."
