Epistemic kind: reconstruction

## Question

Can a change of representation replace repeated computation with operations on a reusable surface?

## Formulation

Explore encoding a spatial or temporal structure in an interference-like representation and computing changes or views from it; evaluate preparation cost, reconstruction cost, approximation, and representational limits.

## Tension

A cheap view after expensive preparation is beneficial only for a suitable pattern of reuse.

## Challenge

Which updates remain local after the transformation, and which require recomputing the surface?
