Builds per-scene L1 in unshackle (PQ mean, letterbox-aware) with a generate_dv_mode config (v29/v40/legacy); a failed hybrid no longer exits 0 with no video.
--proxy now overrides HTTP(S)_PROXY and the Windows system proxy while keeping the env CA bundle. Core fallback sessions use the run's proxy, and a warn-only audit hook names service code that sends a request or opens a raw socket outside the proxy; a session with proxy_exempt = True opts out.
A service that sets the flag gets no cookie load, no authenticate() call and no cookie save on a search, on the CLI and in the REST search handler. /api/services reports it as anonymous_search.
A REST job shows a wait_for_approval message as its notice field. search, list-titles and list-tracks fail at once on a login that needs the user. A remote client downloads through the --proxy it sends.
Regions in GEOBLOCK refuse the service and everything else is allowed. A hit stops the run with a region error instead of auto-proxying; the check also covers proxy exits and the remote-dl client region.
Uppercase entries in ALIASES never resolved, because get_tag lowercased the input but not the alias. Match real tags first so a service's own tag cannot be taken by another service's alias.
Delete the dead grouped-download block, the planner, and the music service hooks; Song now flows through the one download loop, gets tagged via tag_file, and answers -w with {disc}x{track} keys.
BREAKING CHANGE: GROUP_AUDIO_DOWNLOADS, get_music_track_options and get_music_collection_label are gone. A music service returns one Audio track per quality and lets the framework choose.
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.
