 Every PR that changes shipped code (anything under `server/`, `webapp/`, or `docker/` except tests and in-tree docs) ships one; CI (`verify-changesets`) enforces it.

 The summary lands in the changelog **verbatim**, in the operator/user's voice — lead with what they can now
 do, or the symptom a fix removes. No class/hook/file names. No agent-attribution trailers. One changeset per
 user-visible change; unsure whether it's visible? Add one — a reviewer can delete it, a missing note can't.
