A parked folder whose name parses to a registered show merges into the row
that owns the show. The proof is the episode rows standing under the owner
folder — never the id-less folder list, because one tvdb id can carry two
`Series` rows and an id-less folder that parses gets identified on its own
and keeps its own folder, offering the show twice.
No library file moves while `Scan Media Library` is Running: wait for a
Running sighting and then two consecutive Idle polls, because a gap between
sub-tasks reads as finished. Both sides speak different path dialects (the
server records the container coordinate, the journal speaks the array), so a
join that forgets the translation reads as an empty library.
Lands on [[Media TV Relayout]] — the page that owns the TV arm — so
`Media Relayout.md` stays under the OKF ceiling.
