+
+### Added
+
+- **`NavidromePlaylistCoverUploading` protocol** — Navidrome-native REST API seam for uploading playlist cover images. Entirely separate from the Subsonic/OpenSubsonic layer; requires JWT authentication via Navidrome's `/auth/login` endpoint.
+
+- **`NavidromeNativeAPI` struct** — Concrete `Sendable` implementation of `NavidromePlaylistCoverUploading`. Uses the existing `HTTPTransport` seam (zero new dependencies). Provides `authenticate(baseURL:username:password:)` and `uploadPlaylistCover(baseURL:token:playlistId:imageData:mimeType:)`.
+
+- **`NavidromeNativeAPIError` enum** — Typed, credential-safe errors: `.authenticationFailed`, `.uploadFailed(statusCode:)`, `.networkError(underlying:)`, `.invalidResponse`. All `localizedDescription` strings redact credentials.
