만들어지는 프로젝트, 그리고 Swift 6

# ONE universal target (cwkPippa IOS-NATIVE-DELIVERY §4.1): iPhone and iPad.
# Delivery is TestFlight, internal group only; a cable install is a build check.
#
# The wire lives in the local SwiftPM package CordeliaKit (swift test on a Mac);
# shared family Swift comes from cwkSiblingKit's CwkKit as a path dependency.
#
# Regenerate the project with `xcodegen` in this directory; the .xcodeproj is
# generated output, never hand-edited and never committed.

/// Pippa's mouth: plays the audio Oriel sends on the device's speaker, a line
/// Bellows just voiced or one cwkPippa already synthesized (never twice).
///
/// While the ears are closed for her line (the default), the session is
/// playback only, so her own voice can never reach a listener. With Cut-in on
/// the ears keep their play-and-record session open and the line plays through
/// it, so the wake phrase or a tap can stop her (`stop()`). Playback ignores
/// the ring/silent switch, as a voice someone asked for should. AVAudioPlayer
/// lives on the main actor; its delegate is called there.
