The payoff for the previous five commits. Two new download
sources slot into the existing DownloadSourcePlugin contract,
backed by Prowlarr (search) + the torrent or usenet client
adapter (transfer) + archive_pipeline (post-extract walk). They
appear in the Download Source dropdown next to Soulseek / Tidal /
Lidarr / etc. and also participate in hybrid mode.
Pipeline (both plugins, mirror shape):
1. search(query) → ProwlarrClient.search filtered to the right
protocol, projected into TrackResult / AlbumResult shapes the
existing search UI already speaks. Filename field encodes the
indexer's download URL (or magnet URI for torrents) so
download() can recover it later.
2. download() → decodes URL, hands it to the active adapter
(qBittorrent / Transmission / Deluge for torrent; SABnzbd /
NZBGet for usenet), spawns a background poll thread that
tracks progress + reports the adapter-reported save_path.
3. On 'seeding' / 'completed' → archive_pipeline walks the save
directory, extracts any archives the downloader didn't
already unpack, picks the first audio file as the canonical
file_path. Matches the Lidarr client's single-track-pick
contract — picking which specific track to import happens in
post-processing.
- core/download_plugins/torrent.py: TorrentDownloadPlugin +
module-level helpers (_decode_filename, _guess_quality_from_title,
_parse_indexer_id_filter, _adapter_state_to_display, _row_to_status).
Uses get_active_torrent_adapter() so a settings change to the
client type takes effect without restart.
- core/download_plugins/usenet.py: UsenetDownloadPlugin —
parallel shape, reuses the torrent module's helpers. Different
enough states (no seeding, no magnet) to warrant its own class
but cheap to keep in lockstep.
- core/download_plugins/registry.py: register 'torrent' and
'usenet' plugins. Per the registry docstring this is the only
wiring point needed — the orchestrator picks them up
automatically via the iteration helpers.
- webui/index.html: 'Torrent Only (via Prowlarr)' + 'Usenet Only
(via Prowlarr)' added to the Download Source dropdown. New
redirect card (#prowlarr-source-redirect) explains that the
actual config lives on the Indexers & Downloaders tab —
shown whenever torrent or usenet is in the active source set.
- webui/static/settings.js: HYBRID_SOURCES gets two new entries
so hybrid mode can pick them up. updateDownloadSourceUI now
toggles the redirect card based on active sources.
- tests/test_torrent_usenet_plugins.py: 23 tests covering pure
helpers (filename encode/decode round-trip incl. magnet URIs,
quality guesser, state mapping), search projection logic
(protocol filter, drops without URLs, magnet-preferred-over-URL,
filename encoding, neutralised soulseek-specific score fields),
is_configured (both prowlarr + adapter required), finalize
(picks first audio file, errors on empty dir / missing save_path),
clear/get_all lifecycle, DownloadSourcePlugin protocol
conformance, and registry membership.
Follows the exact same standard as Tidal, Qobuz, HiFi, and Deezer.
registry.py — import + register AmazonDownloadClient as 'amazon'.
amazon_download_client.py — read amazon_download.quality / allow_fallback
from config on init; pass quality as preferred_codec to AmazonClient;
_download_sync codec waterfall respects allow_fallback flag.
download_orchestrator.py — reload_settings() updates preferred_codec +
allow_fallback on the live client after a settings save. 'amazon' added
to _streaming_sources so search_and_download_best routes it correctly.
api_call_tracker.py — 'amazon' registered in RATE_LIMITS (120/min),
SERVICE_LABELS, and SERVICE_ORDER so API call monitoring shows Amazon.
web_server.py — 'amazon_download' added to the settings service loop.
'amazon' added to serverless_sources (no slskd probe needed). Streaming
file-finder extended to handle amazon username + ||asin||title encoding
(extension-less fuzzy match, same as Tidal/Qobuz/HiFi). New endpoint:
GET /api/amazon/test-connection → checks T2Tunes proxy status.
webui/index.html — amazon-download-settings-container: quality dropdown
(flac/opus/eac3), allow-fallback checkbox, test-connection button.
webui/static/settings.js — 'Amazon Music' added to HYBRID_SOURCES,
_hybridSourceEnabled, allSources mode list, loadSettings(), saveSettings()
payload, updateDownloadSourceUI() show/hide + auto-test. New
testAmazonConnection() function.
`core/download_plugins/` defines the canonical interface every
download source must satisfy and the registry that holds them.
Single source of truth replacing the orchestrator's hardcoded
`[self.soulseek, self.youtube, ...]` lists scattered across 6+
dispatch sites.
Pure additive — no consumers wired through the registry yet.
