A scan answers 204 whether or not it found anything, so proof is the journal
replayed against Jellyfin's BaseItems.Path and Plex's media_parts.file: every
move has a row at its dst, no row names its src. Records the four wrong doors:
no sqlite3 binary on the hosts or in either container, Jellyfin's single
BaseItems table (no MediaItems), its container-side /data path prefix, and
Plex's HTTPD closing on ?path= / on /search matching titles not paths.
