# Study 000H Discussion

The archive now points to a more complete mechanism chain:

`cadence protection helps preserve expression`

but

`envelope support helps determine whether that preserved expression remains low burden`

This matters because it means the archive is no longer choosing between cadence and context. It is showing how they interact. Rhythm protection appears to be one mechanism. Embedding support appears to be one of the conditions that lets that mechanism succeed more cleanly.

The most important caution is that `000H` identifies the strongest supported support factors, but does not prove a single exclusive switch. Bout length may still matter in a meaningful way, and the archive is not yet large enough to separate every support variable cleanly.
