Tests whether an LLM can produce cross-view-consistent silhouettes of a known object (L-bracket).
This decides whether the Scanner architecture is viable. Pass = pivot. Fail = stay on v4. One round-trip.
Setup
Test object: L-bracket, 80×80×6mm, 90° fold at midpoint, 4 mounting holes (M5 clearance, one per leg quadrant).
The LLM is asked for three orthogonal silhouettes (front / side / top) as polygon vertex lists in millimetres.
