nightingale

Highlights

• Self-hosted web mode (v1) — Nightingale now ships a second binary, server, that runs the same app over HTTP on a Linux box on the LAN. The React bundle is embedded into the binary via rust-embed, browsers on phones/laptops/tablets/TVs all open the app at http://<hostname>.local. A one-shot scripts/install.sh drops a systemd unit, a Caddy front-door (HTTP on :80, opt-in HTTPS via Caddy's local CA on :443 for mic capture), and an avahi advertisement onto the host so it's reachable without DNS. See docs/self-hosted.
• Jellyfin media provider — connect the library to a Jellyfin server from the sidebar. Items are scanned via paginated GET /Items with SortName for stable enumeration; bytes are downloaded lazily on first analysis into cache/sources/<file_hash>.<container> and rekeyed to a true Blake3 hash, so the rest of the karaoke pipeline (stems, transcription, shifts) behaves identically to a folder library.
• Navidrome / Subsonic media provider — same shape as Jellyfin, but talking the Subsonic API. Audio-only (Navidrome doesn't serve video). Auth uses per-call MD5(password + salt) tokens; the password is encrypted at rest in config.json.
• Lyrics editor with LRCLIB browser — every song now has an "Edit lyrics" entry that opens an editor seeded with the current transcript. When LRCLIB returns multiple candidate matches, a second tab lets you carousel through them and apply one with a single click. Saving re-runs alignment with your edits, so timing stays accurate.
• Sidebar restructure — Library actions (folder picker, Jellyfin/Navidrome connect, rescan), cache actions (clear all / videos / models), and the theme toggle moved out of the avatar dropdown into dedicated clusters. The Library row exposes its source buttons inline with live status badges (green/grey/amber) and tooltips showing the reachable hostname or the connection error. The avatar dropdown is now Profile / Settings / Update / About / Exit / Re-run Setup.

Improvements

• Persistent scroll — sidebar and song-list scroll positions are preserved when navigating away and back, via a new usePersistentScroll hook keyed by panel id.
• Higher-contrast sidebar surfaces — various sidebar/menu surfaces had their contrast bumped after the cluster restructure, mostly for the badges and the focused/hovered ring states.
• app-core crate extraction — all cross-runtime logic (config, scanner, library DB, vendor bootstrap, sources, secrets, media server) was lifted out of client/src-tauri into a new app-core crate consumed by both the Tauri desktop client and the new self-hosted server. Drops a chunk of duplicated code and removes the few client/server divergences that had crept in.
• library_db modularization — the single 1k-line library_db.rs was split into connection, migrations, queries, songs, analysis_queue, remote, and rebase. Remote-source helpers live in library_db::remote so Jellyfin/Navidrome share the prune/upsert plumbing.
• Single-focus refactor — use-menu-nav.ts was split into menu-nav/{use-menu-nav-input, use-menu-nav-refs, use-mouse-menu-focus, use-nav-lock, use-scroll-to-song, use-tab-panel-switch}. Resolves a pile of edge cases where focus could land in two panels at once or get stuck after dialog dismissal.
• mic_mirroring → mic_monitoring — the setting and its config keys are renamed (mic_monitoring, mic_monitor_gain, mic_active). Older configs with mic_mirroring / mic_mirror_gain are read transparently via serde aliases and rewritten under the new names on next save. Existing UI hotkeys (R to toggle, etc.) are unchanged.
