Broque Thomas	6fe85f2f37	Server playlist sync: append mode (preserve user-added tracks) ... Discord report (CJFC, 2026-04-26): syncing a Spotify playlist to the server overwrote anything manually added to the server-side playlist. The fix adds a per-sync mode picker next to the Sync button on the playlist details modal — Replace (default, current delete-recreate behavior) or Append only (preserves existing tracks, only adds new ones). Useful when the source platform caps playlist size and the user is manually building beyond it on the server. Implementation: * New `append_to_playlist(name, tracks)` method on Plex / Jellyfin / Navidrome clients. Each uses the server's NATIVE append API: - Plex: `existing_playlist.addItems(new_tracks)` - Jellyfin: `POST /Playlists/<id>/Items?Ids=...&UserId=...` - Navidrome: Subsonic `updatePlaylist?songIdToAdd=...` Falls back to `create_playlist` when the playlist doesn't exist yet (first sync). No delete-recreate, no backup playlist created (preserves playlist creation date + metadata + non-soulsync-managed tracks). * Dedup-by-server-native-id (ratingKey for Plex, GUID for Jellyfin, song-id for Navidrome) — never re-adds a track already on the playlist. Server-native identity, not fuzzy title+artist match, so it can't false-collide. * `sync_service.sync_playlist` accepts `sync_mode='replace'|'append'` kwarg. Single if/else branch dispatches to `append_to_playlist` or `update_playlist`. Threaded through `core/discovery/sync.run_sync_task` and the `/api/sync/start` HTTP handler. Validation on the API rejects unknown mode strings (defaults to 'replace'). * Frontend: per-playlist `<select id="sync-mode-${id}">` rendered next to the Sync button in both modal renderers (sync-spotify.js for Spotify playlists, sync-services.js for Deezer ARL playlists). `startPlaylistSync` reads the select at click time; missing select (other callers like discover.js) defaults to 'replace' so backward compat preserved without per-call-site updates. * SoulSync standalone has no playlist methods at all and the modal hides the Sync button entirely on it via `_isSoulsyncStandalone` — dispatch never reaches that path, no defensive fallback needed. 15 new tests pin per-server append behavior: - missing playlist → create_playlist delegation - dedup filtering (existing IDs skipped, only new tracks added) - empty new-track set short-circuits without API call - failure paths return False without raising - contract listing (KNOWN_PER_SERVER_METHODS includes 'append_to_playlist'; Plex / Jellyfin / Navidrome all implement) Plus tests/discovery/test_discovery_sync.py fake `sync_playlist` fixture got `sync_mode='replace'` default to match the new signature (was breaking after the kwarg add; now passing). WHATS_NEW entry under new '2.6.0' block (hidden by `_getLatestWhatsNewVersion` until next release bump). Closes CJFC discord request.	2 weeks ago
Broque Thomas	e27ecb84f4	Final review-pass nits — class docstring, dead branch, dead imports, boot resilience ... Going line-by-line through the engine package + boot wiring. Five small things worth fixing before Cin reads it: (1) MediaServerEngine class docstring still claimed to be a "single entry point for cross-server library operations" — but the prior honesty pass cut all the cross-server dispatch wrappers because they had no callers. Class is really lookup + small accessors now. Docstring rewritten to match. (2) configured_clients() had a dead `not hasattr(client, 'is_connected')` branch. is_connected is in REQUIRED_METHODS so every client the registry yields here implements it. Branch removed; comment notes the reasoning. (3) types.py imported `datetime` and `Dict` but used neither — dead imports dropped. (4) types.py docstring claimed "all four servers" defined an XTrackInfo dataclass. Actually only Plex / Jellyfin / Navidrome did; SoulSync uses richer per-track wrappers. Fixed. (5) web_server.py boot: - media_server_engine added to the chained `= None` declaration so it's always defined before the try/except, defending against the rare path where engine init AND fallback both raise. - Outer engine init failure logger now uses exc_info=True for full traceback (boot-time issues are rare but worth diagnosing). - Nested fallback failure now logs explicitly instead of silently leaving media_server_engine as None. Tests: 2121 still pass.	3 weeks ago
Broque Thomas	6489244bcc	MS Cin/JohnBaumb honesty pass — drop dead wrappers, sync contract to reality ... Pre-review audit found premature abstraction + lying docstrings. Cut what isn't used, made the rest match what's actually shipped. (1) Engine: dropped 7 cross-server dispatch wrappers that had ZERO production callers (ensure_connection / get_all_artists / get_all_album_ids / search_tracks / trigger_library_scan / is_library_scanning / get_library_stats / get_recently_added_albums). Every consumer reaches the active client directly via sync_service._get_active_media_client() or engine.client(name). Engine surface shrinks to client(name) / active_client() / active_server / is_connected() (the one wrapper that has callers — 4 dashboard status sites) / configured_clients() / reload_config(). ~150 lines deleted, 5 dead-method tests removed. (2) Contract Protocol body trimmed to match REQUIRED_METHODS exactly (is_connected, ensure_connection, get_all_artists, get_all_album_ids). The other 5 methods that were declared in the Protocol "required" section weren't actually required — Plex doesn't implement get_recently_added_albums, Jellyfin doesn't implement search_tracks, SoulSync doesn't implement most of them. Static contract now matches runtime conformance test. Optional methods moved to a KNOWN_PER_SERVER_METHODS data-only listing with audited per-server coverage notes — discoverability without false promises. (3) Engine module docstring + __init__.py docstring no longer overclaim "33+ chains collapsed" — only 4 uniform-shape chains were collapsed; ~18 server-specific chains stay explicit per the "lift what's truly shared" standard. Phrasing now matches reality. (4) types.py docstring claimed TrackInfo.from_jellyfin_dict and TrackInfo.from_navidrome_dict exist as classmethods. They don't — only from_plex_track / from_plex_playlist do. Jellyfin and Navidrome construct TrackInfo inline at their call sites today. Docstring now honest about that + flags the lift as a clean followup. (5) Engine line 95 comment "backward-compat for source-specific reaches" was misleading — there is no legacy alternative being preserved; engine.client(name) IS the canonical access pattern. Section header rewritten. Tests: 2121 pass (was 2126; -5 dead-method pin tests).	3 weeks ago
Broque Thomas	99f527ecd1	MS pre-review polish followup — log levels + docstring honesty ... Three nits I missed in the prior pass: (1) Two more exception swallows still at logger.debug — the get_recently_added_albums wrapper and the configured_clients inner loop. My earlier sed only matched single-line patterns. Both now log at warning level so a broken Plex / Jellyfin surfaces in the boot log instead of silently returning []. (2) registry.py module docstring still claimed it replaced "33 hand-maintained dispatch sites" — same overclaim I fixed on the engine docstring. Server-specific chains stay explicit in web_server.py per the "lift what's truly shared" standard; the registry just owns name → client lookup. Docstring rewritten to match reality.	3 weeks ago
Broque Thomas	860f9a0a8c	MS pre-review polish — encapsulation + visibility + tests ... Five tightening passes anticipating Cin / JohnBaumb's review nits: (1) Engine no longer reaches into ``registry._instances`` private attr. New public ``MediaServerRegistry.set_instance(name, client)`` method — engine constructor calls it for the ``clients=`` pre-built case so internal storage stays encapsulated. (2) Engine module docstring no longer overclaims. Originally said it "Replaces the historic 33+ if/elif chains" — but only the four uniform-shape ``is_connected`` chains were collapsed. The 19 chains that do server-specific work (Plex raw API vs Jellyfin / Navidrome client methods returning different shapes) stay explicit per the "lift what's truly shared" standard. Docstring rewritten to say exactly that. (3) Per-method exception swallows upgraded from ``logger.debug`` to ``logger.warning``. Returning safe defaults stays the right behavior for a read-side engine (Plex offline shouldn't crash the app), but silent debug-level swallowing made debugging hard — JohnBaumb pushed the download engine to surface real errors. Same treatment here: default still safe, but the warning tells you Plex is down. (4) ``_safe_init_media_client`` in web_server.py now logs the exception type + traceback. Broad ``except Exception`` is still intentional (any failure means that one server can't be used; the others stay up) but the boot log now distinguishes config errors (ConnectionError, AuthenticationError) from import / dependency failures. (5) Two new tests pin the encapsulation + fallback contracts: - ``test_engine_with_empty_clients_dict_is_safe_to_use`` — empty engine returns safe defaults on every method, doesn't raise. - ``test_engine_uses_registry_set_instance_not_private_attr`` — spy on registry.set_instance verifies engine uses the public method.	3 weeks ago
Broque Thomas	2ebaf2e6e3	MS Gap 1: Lift shared TrackInfo + PlaylistInfo to neutral types module ... Plex / Jellyfin / Navidrome each defined a near-identical XTrackInfo (id / title / artist / album / duration / track_number / year / rating) and XPlaylistInfo (id / title / description / duration / leaf_count / tracks). Three classes that grew up by copy-paste — not a real contract difference. Lifted both to core/media_server/types.py as canonical TrackInfo + PlaylistInfo. Per-server constructors live as classmethods on the unified class (TrackInfo.from_plex_track, PlaylistInfo.from_plex_playlist) matching the metadata Album.from_X_dict pattern Cin's POC uses. Heavy plexapi imports stay lazy under TYPE_CHECKING. - core/plex_client.py / jellyfin_client.py / navidrome_client.py: per-server XTrackInfo / XPlaylistInfo dataclass definitions removed; each module now imports TrackInfo + PlaylistInfo from the neutral package and uses the shared name internally. - core/matching_engine.py: was annotating callers with PlexTrackInfo even though sync_service hands it Jellyfin / Navidrome instances at runtime when those servers are active. Annotation is now the unified TrackInfo, so signatures match the actual contract. - services/sync_service.py: same import + annotation update.	3 weeks ago
Broque Thomas	49f7679eef	MS Cin-1 + Cin-2: Explicit contract inheritance + generic accessors ... Apply the Cin-1 / Cin-2 pattern from the download refactor PR to the media server engine PR before review. Cin-1 — explicit inheritance: - PlexClient, JellyfinClient, NavidromeClient, SoulSyncClient now explicitly inherit MediaServerClient instead of relying on structural typing alone. Pre-change a reader of plex_client.py had no way to know the class was supposed to satisfy the contract. - Removed the engine + registry re-exports from core/media_server/__init__.py to break the circular import that the inheritance change introduced (importing the package now triggered a chain that loaded clients before their base class resolved). Submodules import directly: from core.media_server.engine import MediaServerEngine, etc. - Conformance test now also asserts isinstance() / issubclass() against MediaServerClient — drift in any class fails at the test boundary instead of at runtime. Cin-2 — generic accessors + singleton: - engine.configured_clients() — replaces the legacy per-server `if X and X.is_connected(): clients[name] = X` chains in web_server.py. - engine.reload_config(name=None) — generic dispatch, so callers pass the server name instead of reaching for plex_client.reload_config() directly. - get_media_server_engine() / set_media_server_engine() singleton factory matching the get_metadata_engine() / get_download_orchestrator() shape. web_server.py boots via set_media_server_engine(...) so factory + global handle share state. - 7 new tests pin the accessors + singleton behaviour.	3 weeks ago
Broque Thomas	971d683ebd	C1: Migrate status-check dispatch sites to engine ... Two sites in web_server.py replaced: - /status route's media-server connectivity check (4-way if/elif for plex/jellyfin/navidrome/soulsync) → engine.is_connected() - /api/playlists endpoint's server_connected check (3-way if/elif) → engine.is_connected() Engine reads active_server config + dispatches to the right client with internal connection caching preserved (the underlying clients all cache is_connected() calls). Engine constructor now accepts a pre-built clients={...} dict so web_server.py wires the same instances as its existing per-client globals — no double-init. Suite still green. Per-server clients still accessible via engine.client(name) for source-specific reaches.	3 weeks ago
Broque Thomas	6b54ca6598	Phase B: Add MediaServerEngine skeleton ... `MediaServerEngine` reads the active server from config + dispatches to the corresponding registered client. Per-server reaches still work through `engine.client(name)`. Required-method dispatch (is_connected, ensure_connection, get_all_artists, get_all_album_ids) returns safe defaults when the active client failed to initialize OR when the method raises. Optional-method dispatch (search_tracks, trigger_library_scan, is_library_scanning, get_library_stats, get_recently_added_albums) checks hasattr first — SoulSync standalone has no trigger_library_scan or get_library_stats, engine no-ops with appropriate defaults instead of forcing every client to declare stub methods. 10 new engine tests pin: active-server resolution, required dispatch routing, exception safety, missing-optional-method fallback shape. Suite still green (1951 passed). Engine isn't on any production code path yet — Phase C migrates the 33 web_server.py dispatch sites to call engine.method() instead of hand-branching by active_server name.	3 weeks ago
Broque Thomas	f702196dca	Phase 0: Add MediaServerClient contract + registry ... `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).	3 weeks ago
