# Study 000H: Envelope Support Factors

## Core Question

What seems to determine whether a cadence-protected outside-surface run becomes high-burden or low-burden?

## Answer

The strongest supported envelope-support factors are high local running embedding and stabilized-context continuity. Longer bout structure appears to be a plausible secondary factor, but is not isolated as cleanly as embedding in the current dataset.

## Thesis

`Cadence protection appears to preserve running expression, but envelope support appears to determine whether that mechanically preserved expression remains physiologically tolerable.`
