Source custody

Recent source checks across the inventory.

Access dates document observatory custody. The source dossier records citation text, publisher, license posture, linked markets, and encoded uses.

Availability standard

Period, place, rows, and custody travel together.

This atlas inventories rows encoded in the current observatory release. A measurement year is not a source access date, an empty year cell does not establish that no underlying public data exists, and observed coverage does not imply a publisher schedule or forecast a future release.
