# Applies the 'fields' array of the envelope to application.yml. Restart required to apply.

`PATCH /application-config`

Accepts the same envelope shape returned by GET: { fields, comments }. Nodes are matched by 'path' — values are edited, new keys added, and nodes with status 'inactive' are commented out. 'comments' is read-only and ignored on write; comments on disk are preserved automatically.
