<a name="assets-join-table">1</a>: This is actually a dynamically named table of the form `Z_##ASSETS`. The ## is the `Z_ENT` value for the record with `Z_NAME = 'Album'` from the `Z_PRIMARYKEY` table. It always appears to be 26 for the macOS Photos library but in [this post](https://www.forensicmike1.com/2019/05/02/ios-photos-sqlite-forensics/) it is `Z_23ASSETS` for an iOS Photos library.
