root/doc/edit_type.tt (the documentation for a specific edit type, e.g. https://musicbrainz.org/doc/Edit_Types/81)

Much of the info in that table is no longer relevant (voting period is now always 7, needed votes always 3, and every edit is accepted on expiration). I'd suggest dropping those, and adding a new row for whether an edit type is always an autoedit unless explicitly made votable (such as Add artist).
