Get Guideline

One guideline's requirements, in the order they were extracted.

Polled by the detail view while a decomposition runs, which is exactly when the previous generation has just been retired — so state is not a convenience. Every regeneration leaves another permanent generation behind, and without a filter here the payload carries all of them and the browser discards most of it, on every poll. superseded_with_human_edits is counted separately so the surface can still offer to show them.

Carries no presigned URL: signing is not idempotent, so a URL on a polled payload changes every tick and remounts the document viewer. The viewer gets its URL from usePreviewUrl.
