Cache keys are now the path relative to the service cache dir without .json, so Cacher keys like session_web/<sha1> reach the remote session. The credential filter runs on every path segment, the suffix is appended rather than substituted, and both sides cap the map at 64 keys.
Answered login prompts and uploaded cache now count as client auth; the client closes on exit and keeps the remote session alive during long downloads.
The licence response lists KIDs a server vault supplied, the client proves them with the decode check, and a bad pair goes to the new session keys/bad route so the server flags its own row. Client vault keys go first over --remote, and the dashboard health warns when no SQLite vault can store flags.
A service can build an AdaptationSet the served manifest does not contain, so the client's re-parse could never find it and the track downloaded with no manifest data. Those tracks now get a one-AdaptationSet MPD of their own.
The client withheld nothing before: every profile's tokens went to any remote server. Filter by active-credential digests and profile names, keeping service-global files; worst case for a withheld file is a server-side re-auth.
Mirror each remote session's self.log into a bounded buffer, drained by the client via GET /api/session/{id}/logs and re-emitted locally. Server-account sessions get no relay. Also namespace service CLI options under service_params so a transport key (profile) no longer collides with a service's own option, on both the session and download-job paths.
serve.server_accounts lends region-tagged server credentials to remote sessions (round-robin per region, per-key opt-in, per-account cache). Remote sessions no longer fall back to the server's local credentials when the client sends none.
Add POST /api/session/{id}/segment_filter: the server runs the service's OnSegmentFilter and returns only the unwanted segment URIs, so ads and bumpers are dropped over --remote-only without exposing service code.
The server no longer spends its configured proxy providers on a remote client unless the API key sets server_proxy. It places the client by geolocating the connection address and asks for a proxy when that region does not match its own.
Services set the original language, track names, repack flags, editions and track.data inside get_tracks; the client dropped them so --remote muxed with no default audio and could not select "orig". Also round-trip Song titles, subtitle DRM, PlayReady PSSH, exact bitrate and path-only attachments.
Renames 314 defs and 41 module/class-level constants. Keeps 11 names underscored where the stripped form collides in scope, plus 5.5.0 shims for the three symbols external service repos call.
Adds prompt_user() and uses it for local, remote, and Proton VPN input. Replaces click.prompt on the remote auth path, which ignored the theme and overlapped active Live displays. Remote auth now exits on EOF instead of POSTing an empty answer and spinning the poll loop.
