Document versions
Rows may capture the same summary from different sources or formats (the provider's site, AIAL's archived copy); sizes and hashes are comparable only within one URL.

Watch-surface captures
Captures of the page(s) where the document is published (portals, hubs, docs pages) — monitored for change detection; not the document itself.

Captures of superseded target URLs
Locations this ledger previously tracked for this source (per-row notes give the reason each was superseded) — kept as faithful records of what those URLs served at capture time.
