Epistemic kind: reconstruction

## Question

What is computation when reading changes the stored state?

## Formulation

Reading, writing, and transition are explored as coupled operations. A repair path may disturb what it reads while trying to restore another disturbance.

## Tension

An inspection path may alter the very history it was meant to recover.

## Challenge

Which state variables and intervention costs must be included for a claim of reversibility?
