Build pinned LGPL playback libraries and package standalone YouTube helpers inside the signed native app. Keep the CLI inside the app and relocate private library links for installation without runtime Homebrew dependencies. Record adaptive fixture completion in its EXIT trap: cancellation can exit with status 143 before the TERM trap writes its marker, while native pause and quality preservation remain correct.
