officer-jellyfin owns the whole Jellyfin contract: the instance URL, the access
token, the Jellyfin user it belongs to and the DeviceId its sessions are keyed
by. The platform side is a 17-line proxy holding no credentials.
Servers are a registry, not a single row — this machine runs four instances and
the owner switches between them. The password is never stored: it is traded once
for an access token through AuthenticateByName, and only that token is persisted,
encrypted.
Two doors. /_officer/* is a hand-written JSON façade for the things the browser
should not have to know — the user id in the path, the Fields lists that decide
whether a grid has posters, the PlaybackInfo negotiation. /_jf/* is a GET-only,
allow-listed byte pass-through for images, video, HLS and subtitles; it keeps
Jellyfin's own paths because a master playlist references its segments
relatively, so any renaming would mean rewriting m3u8 bodies.
TranscodingUrl arrives with api_key=<access token> in its query string and would
otherwise be handed straight to a video element. It is stripped before anything
is returned; the pass-through re-adds the credential as a header.
Video only — Officer's own player owns audio, so music collections are filtered
out of the library list.
