# Exposure Card: Route-State Topology, Retention, And Reset

## Possibility

A spatially and temporally organized route grammar can write, retain, read, and
reset a physical state whose useful structure depends on distributed
coactivation rather than total dose alone.

## Public Question

Can a predeclared route program create a retained state that survives
orthogonal readout, reset, fatigue, environmental controls, and sample-variation
stress?

## Frozen Comparison

- Same target state and total declared drive envelope
- Structured route program versus uniform-dose and permuted-route controls
- Fixed readout and reset rules
- Held-out cycles and samples
- Matched thermal, drift, damage, and support accounting

## Measurements

- retained-state fidelity;
- reset completeness and cycle-to-cycle recovery;
- orthogonal readout agreement;
- fatigue and sample-variation distribution;
- route-destroying and equal-dose control response;
- energy, timing, calibration, and support front.

## Decisive Branches

- **Persists:** retained structure follows route organization across held-out
  cycles and orthogonal readouts.
- **Closes ordinarily:** total dose, heating, damage, drift, or readout artifacts
  explain the retained state.
- **Narrow:** a bounded route grammar survives with an explicit fatigue,
  variability, or reset limit.

orthogonal-readout, and matched-resource summaries.
