The page sent the next agent to POST /Items/{id}/Refresh?Recursive=true per
library to make a new folder visible. Measured against a Shows library that had
never been identified: that route answers 204 and queues nothing — item census
byte-identical, ScheduledTasks idle, journal silent, and still a silent 204 after
a service restart. The door that works is POST /Library/Refresh, and the progress
read is ScheduledTasks -> Scan Media Library -> CurrentProgressPercentage.
RefreshStatus on the VirtualFolders record stays Idle through a real scan, so it
is not a progress read at all; a 204 cannot distinguish accepted-and-discarded
from accepted-and-queued, so the acceptance read is the journal naming folders.
Also recorded the art door's wire shape, because guessing it reads as a server
bug: the list response carries the address in Url (there is no ImageUrl), the
Download POST takes camelCase type/imageUrl and answers 204, and PascalCase or an
empty imageUrl answers 500. RemoteImages is empty for items with no ProviderIds,
so art coverage is capped by identification, not by the image door.
