Detailed Description

One page's dedup/verify record in the series-wide pool.

url_hash keys a source URL so a re-fetch of the same image (a rerun, or an image shared between chapters) is found without the network; content_hash is the byte identity used to verify a page already on disk and to prove a reused copy is truly identical.

Invariant

rel_path is a sanitised path relative to the series directory.
