Automatically mirrors every parsed playlist (Spotify, Tidal, YouTube, Beatport) to a local database so they're always accessible — even if a service subscription lapses or the browser closes.
- New "Mirrored" tab on the Sync page with source-branded cards showing discovery/download status
- Auto-mirrors on successful parse (upsert — re-parsing updates the existing mirror, no duplicates)
- Click any mirrored playlist to browse its full track list, then run it through the discovery pipeline
- Cards dynamically reflect live state: Discovering → Discovered → Downloading → Downloaded
- Download modal rehydrates after page refresh — click a "Downloading..." card to resume viewing progress
- All phase transitions (start, complete, cancel, error, modal close) keep card and backend state in sync
- Profile-scoped via profile_id, consistent with other features
Allow multiple users to share a single SoulSync instance with isolated personal data. Each profile gets its own watchlist, wishlist, discovery pool, similar artists, and bubble snapshots — while sharing the same music library, database, and service credentials.
- Netflix-style profile picker on startup when multiple profiles exist
- Optional PIN protection per profile; admin PIN required when >1 profiles
- Admin-only profile management (create, edit, rename, delete)
- Profile avatar images via URL with colored-initial fallback
- Zero-downtime SQLite migration — all existing data maps to auto-created
admin profile
- Single-user installs see no changes — profile system is invisible until
a second profile is created
- WebSocket count emitters scoped to profile rooms (watchlist/wishlist)
- Background scanners (watchlist, wishlist, discovery) iterate all profiles
Migrates 38 HTTP polling loops to WebSocket push events across 6 phases: service status, dashboard stats, enrichment workers, tool progress, sync/discovery progress, and scan status. All original HTTP polling is preserved as automatic fallback — if WebSocket is unavailable or disconnects, the app seamlessly reverts to its previous behavior. Includes 162 tests verifying event delivery, data shape, and HTTP parity. Also fixes a copy-paste bug in Beatport sync error cleanup.
Adds a full public REST API at /api/v1/ with 32 endpoints covering library, search, downloads, wishlist, watchlist, playlists, system status, and settings. Includes API key authentication (Bearer token), per-endpoint rate limiting, and consistent JSON response format. API keys can be generated and managed from the Settings page. No changes to existing functionality — the API delegates to the same backend services the web UI uses.
