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.
New post_scripts config and repeatable --postscript flag run a command per output, season/album folder, or run, substituting filename-template variables into pre-tokenized argv. The REST API rejects hook commands.
Closes#150
Render all click help through rich-click, themed by a new `theme` config key (9 palettes + aliases, previewable via `unshackle env theme`), and show service docstrings in local and remote `dl <TAG> -h`.
api-only/remote-only serve now authenticates every serve.users key (str-coerced), not just api_secret, so per-user service allowlists apply. RemoteClient tries X-Secret-Key then X-Api-Key on 401 (sticky winner); remote_services.auth_headers prepends extra header names to the defaults.
Episode gains an additive absolute field services can set, an {absolute}
naming token (3-wide), and an --enrich fill from TVDB's absolute order
that never rewrites season or episode numbers.
--anilist supersedes --animeapi (REST: anilist_id); the keyless AniList
GraphQL provider joins the registry with title search, mal: ID lookup,
an ANILIST mkv tag, and the anilist_title_language config option.
Services mark anime via Service.ANIME / Title.anime for anilist-first
metadata resolution with fall-through.
Supplied IDs resolve directly via a shared resolve_by_ids and never fall back to title search; metadata_providers gains per-kind ordering and a disable_metadata switch stops all automatic lookups while explicit IDs keep working.
BREAKING: --tmdb/--imdb/--tvdb are now mutually exclusive and require a usable provider; --enrich also overwrites original language; the imdbapi provider and imdb_api_enabled are replaced by a keyless imdb provider.
--enrich now sets Title.language when the service left it unset, so video tracks stop falling back to und. Adds original_language to MetadataResult (TMDB, TVDB, OMDb, IMDxAPI) and falls back to OMDb for --imdb, which previously did nothing while imdb_api_enabled defaults to false.
Catch the branch up with dev (45 commits) so testers can run the perf work
against current dev.
Conflict resolutions:
- downloaders/requests.py: keep the branch's racing-gated read1, adaptive
controller speed reporting and byte-range slice guards; take dev's
content-encoding checks (raw reads are skipped on an encoded body) and its
rolling SpeedWindow for the no-controller speed fallback. The single-URL
ranged-parallel gate now requires no speed limit and no caller Range.
- service.py / session.py: keep the branch's TimeoutHTTPAdapter and retry
config, raise POOL_MAX_SIZE to 64 so dev's pool-starvation fix survives
(pool_block=True stalls threads on a pool smaller than the in-flight count).
- docs: dev split configuration.md into per-area pages, so the branch's rnet
network option rows moved to reference/configuration/network.md.
