RESEARCH COMPONENT
BODY / SHADOW
Projection, representation, and what observation leaves unknown
What it is
A body is an underlying represented structure. A shadow is a partial observation or projection. Different bodies may produce identical shadows, while additional relations can eliminate some possibilities.
Reconstructability is a statement about a specified observation map, feasible model class, and equivalence relation. Results may change when labels, symmetries, or observation precision change.
Verification obligations
- Define the model class and observation/projection map.
- Declare whether reflections and label permutations count as equivalent.
- Specify reconstruction conditions and explicit counterexamples.
- Keep static geometric claims separate from mechanical motion or physical dynamics.
Current public evidence
A public four-point worked example, BS-MIN-01, demonstrates how a projection hides a coordinate, a distance reduces ambiguity, and an orientation-sensitive observation distinguishes mirror cases. It is not proof of a universal physical mechanism.
