Broque Thomas	5c8b8b271a	Lift _prepare_stream_task + playlist_explorer_build_tree to core/ ... Final lift in the web_server.py extraction effort. Pulls two route handlers + one background worker out of `web_server.py` into new focused packages: - `core/streaming/prepare.py` — 258-line stream-prep worker that downloads a track to the local Stream/ folder for the browser audio player. - `core/playlists/explorer.py` — 305-line route handler for `POST /api/playlist-explorer/build-tree` that streams an NDJSON discography tree from a mirrored playlist. What `prepare_stream_task` does: 1. Reset stream state to 'loading' with the new track info. 2. Clear any prior file from Stream/ (only one stream lives there). 3. Spin up a fresh asyncio event loop and `soulseek_client.download()`. 4. Poll progress every 1.5s. Queue timeout 15s; overall 60s. 5. On succeeded + bytes-match: find the file with retry, move into Stream/, signal slskd completion, mark state 'ready' with file_path. 6. On error/timeout/cancel: state goes to 'error' or 'stopped'. 7. Finally: tear down the event loop cleanly. What `playlist_explorer_build_tree` does: 1. Validate request, load playlist + tracks from DB. 2. Pick active metadata source (Spotify if authed, else fallback). 3. Group tracks by artist using discovered matched_data when the provider matches the active source. 4. Stream NDJSON: meta line → one artist line per group → complete line. 5. Per artist: cache check → resolve discography → tag releases with `in_playlist` flag based on title-similarity match → filter by mode (`albums` = only matches; `discographies` = full disco). 6. Mark playlist as explored on completion. Strict 1:1 byte parity: Both functions exposed their dependencies through proxy patterns established in earlier lifts (PR4–PR8). For prepare_stream_task, `stream_state` is a deps property; for the explorer, Flask `request` / `jsonify` / `Response` are injected via deps so the lifted body keeps its native syntax. Both lifts verified ZERO diff against the original after `deps.X` → global X normalization. 258 lines orig = 258 lines lifted (prepare_stream_task). 305 lines orig = 305 lines lifted (explorer). Bonus cleanup: web_server.py's module-level `import shutil` and `import glob` were now unused (only `_prepare_stream_task` used them at module scope; every other reference is via inline `import shutil` in respective function bodies). Removed both module-level imports — ruff caught the F811 redefinitions and confirmed they're truly redundant. Dependencies for `PrepareStreamDeps` (11 fields): config_manager, soulseek_client, stream_lock, project_root, docker_resolve_path, find_streaming_download_in_all_downloads, find_downloaded_file, extract_filename, cleanup_empty_directories, plus 2 stream_state property delegates. Dependencies for `PlaylistExplorerDeps` (9 fields): Flask request/Response/jsonify, spotify_client, get_database, get_active_discovery_source, get_metadata_fallback_client, get_metadata_fallback_source, get_metadata_cache. Tests: 6 new under tests/streaming/test_prepare.py (state init, Stream/ folder creation + clearing, download-init failure, completed + moved + ready state, partial-bytes incomplete-warning path) plus 9 new under tests/playlists/test_explorer.py (5 validation early-exit paths, streaming response shape with meta/complete lines, mark- explored side effect, discovered-artist grouping using matched_data, provider mismatch falling back to raw artist name). Full suite: 1355 passing (was 1340). Ruff clean. End of the web_server.py extraction effort. Started at ~45,000 lines across PR4–PR8 + this commit; finished around 35,000 lines with the heavy worker + route logic now living in domain-cohesive packages under core/. The remaining bulk in web_server.py is route handlers, service initialization, and the deferred 1530-line `_register_automation_handlers` (startup-only, marginal lift value).	4 weeks ago
