# gstack-ios-qa-daemon — Mac-side daemon that brokers tailnet/loopback traffic
# to a connected iPhone running the in-app StateServer over the CoreDevice USB
# tunnel. Single-instance via flock on ~/.gstack/ios-qa-daemon.pid.
#
# Usage:
# gstack-ios-qa-daemon # loopback-only (local USB)
# gstack-ios-qa-daemon --tailnet # additionally open tailnet listener
#
# Environment:
# GSTACK_IOS_DAEMON_PORT — loopback listener port (default 9099)
# GSTACK_IOS_TARGET_UDID — target iOS device UDID (optional; otherwise
# the first paired connected device is used)
# GSTACK_IOS_TARGET_BUNDLE_ID — bundle ID of the iOS app hosting StateServer
# (default com.gstack.iosqa.fixture)
#
# Readiness protocol: prints `READY: port=<n> pid=<pid>` to stdout once both
# listeners are bound. Spawners read stdin with a ~5s timeout to confirm.
#
# Exits cleanly when no active loopback clients are connected AND no remote
# session tokens are outstanding.
