// Use when playback, auth recovery, queue sync, or hidden WebView state diverges from native Swift state and you need to debug the DRM playback WebView, bridge events, or cookie/auth behavior.
Use when a task needs a new or modified YouTube Music API call, response parser validation, authenticated endpoint investigation, or fixture capture; explore endpoints with `swift run api-explorer` before changing production code.
Use when you need a fresh packaged `.app` bundle, a fast build-package-relaunch loop, or a packaged runtime repro for Kaset instead of a compile-only verification.
