# Study 000F Submission Guidance

## Best Fit

This study is a strong fit for:

- biomechanics interpretation
- altered-mechanics theory
- movement science
- wearable-data interpretation
- rehabilitation theory building

## Strongest framing

`Within this altered-mechanics archive, successful running expression was better explained by a bounded operating envelope than by surface category alone.`

## What it can claim

- late successful expression clustered into a compact operating region
- outside-cluster burden rose strongly in the October 2025 probes
- the April 2026 boundary probe showed that surface departure did not automatically force high burden
- operating envelope explains more than treadmill-versus-outdoor language alone

## What it should not claim

- that every axis of the envelope is fully mapped
- that mechanism is completely settled
- that transferability is experimentally proven in other diagnoses
