Read the location plates of the script behind a table-read artifact.

The empty rooms every video render places the cast into, as capped canon assets. Every room the script stores or walks through, each lighting variant of it (the same room by day and by night is ONE room with two variants), and per variant the master, medium and close plate in the landscape and portrait pools: status (ready, or missing — made when a video renders), imageUrl, description (the room as the plate shows it, written when the plate was accepted), the judge record note (advisory), the accepted verdict, any remake in flight, and canRemake. duplicates lists rooms stored under two spellings in one light; the read reports them and renames nothing. Plates are never approved. COSTS NOTHING and NEVER makes a plate. Scope: artifact:read.
