Four stale doc/comment references caught by Copilot's pass:
- core/download_plugins/base.py: TYPE_CHECKING comment said the
shared dataclasses lived in core.soulseek_client. They were moved
to core.download_plugins.types in this PR. Comment updated.
- core/qobuz_client.py: reload_credentials docstring still referenced
soulseek_client.client('qobuz') after the global rename to
download_orchestrator. Updated to download_orchestrator.client(...).
- webui/static/helper.js: the older WHATS_NEW entries for the plugin
contract + engine refactor still claimed backward-compat
self.<source> attributes were preserved. Followup commits in the
same PR removed them. Each entry now flags the followup explicitly
and points at the "Drop Backward-Compat Per-Source Attrs" entry
above it so the changelog is internally consistent.
- docs/download-engine-refactor-plan.md: Compatibility commitments
section listed orchestrator.<source> attribute preservation as a
guarantee. Cin's review pass removed those attrs (and renamed the
global handle from soulseek_client to download_orchestrator) — both
are breaking changes for in-tree callers (which were migrated) and
in-flight branches (which will need to update). Section rewritten
to document the actual outcome.
`core/media_server/` package with the Protocol contract that
every media server client (Plex, Jellyfin, Navidrome, SoulSync
standalone) satisfies, plus the registry that holds them.
Required methods conservatively limited to the four every server
truly implements today: is_connected, ensure_connection,
get_all_artists, get_all_album_ids. Other generic methods
(search_tracks, trigger_library_scan, get_recently_added_albums,
etc.) are listed as OPTIONAL — present on most servers but not
all (SoulSync has no library-scan API since it walks the filesystem
directly; Jellyfin uses a different search shape). Phase B's
engine adapters route around the gaps with per-server fallback
instead of forcing every client to declare a no-op stub.
Same registry shape as the download plugin registry — single
source of truth for which servers exist + name resolution. Adding
a 5th server (Subsonic, Emby, etc.) becomes one register call
plus the new client class.
5 conformance tests pin every server class implements every
required method. Plan doc at docs/media-server-engine-refactor-plan.md.
Pure additive — no consumer routes through the contract or
registry yet. Suite still green (1921 passed).
`core/download_engine/rate_limit.py` introduces a per-source
policy declaration: download_concurrency + download_delay_seconds.
Plugins declare via `RATE_LIMIT_POLICY` class attribute or a
`rate_limit_policy()` method.
Engine applies the declared policy to engine.worker at
register_plugin time — set_concurrency + set_delay get pushed
in automatically. Plugins without a declaration get the
conservative default (1 / 0). The set_engine callback fires
AFTER policy registration so config-driven sources (YouTube
reads user-tunable youtube.download_delay) can override.
Plan doc updated to reflect Phase D skip (search code is 90%
source-specific, not 60% — lifting it would be lossy or
bloated).
Pure additive — no plugin migrated yet. 8 tests pin the
resolution priority + engine wire-up + override semantics.
Suite still green (327 download tests).
13 tests pin slskd HTTP API contract: endpoint format
(`transfers/downloads/<username>` POST), payload shape
(slskd web-interface array format), id extraction from dict /
list / fallback responses, and the username-lookup fallback in
cancel_download when no username hint is provided.
Phase A of the download engine refactor — pinning current
behavior of every source BEFORE moving any code so the engine
extraction can't drift the per-source contract. Includes the
plan doc at docs/download-engine-refactor-plan.md.
Pure additive — no client code changes.
Audit caught two missing providers from the foundation pr. Both
return album-shaped data via their clients (search + download
flows). Tidal uses tidalapi objects rather than dicts so the
converter is from_tidal_object, not _dict.
Enrichment-only providers (lastfm/genius/acoustid/listenbrainz/
audiodb) intentionally have no album converter — they enrich
existing rows, never return album shapes.
Tests: +8 cases. 40 total now.
New core/metadata/types.py with canonical dataclasses + classmethod
converters for spotify/itunes/deezer/discogs/musicbrainz/hydrabase.
Each converter is the single place that knows that provider's wire
shape — addresses the duck-typing pattern Cin flagged.
Pure additive: no consumer code changed. Follow-up PRs migrate
consumers one at a time. Migration plan at
docs/metadata-types-migration.md.
Tests: 32 cases pin per-provider semantics + cross-provider
invariants. Also stabilized a flaky discogs test that depended on
local config state.
Add a new docs/api-response-shapes.md describing expected Spotify/iTunes dataclass and raw-dict response shapes and client behavior. Also update core/wishlist_service.py to include 'track_number' (default 1) and 'disc_number' (default 1) in each formatted track dict so consumers receive track ordering metadata.
