Cross-Domain Routing

Camera + permissions (camera access denied, Info.plist missing):

Camera code → stay here (camera-capture)
Privacy manifest / Info.plist → invoke axiom-integration (privacy-ux reference)
Build/entitlement errors → invoke axiom-build

ShazamKit + microphone permissions:

Microphone NSMicrophoneUsageDescription → invoke axiom-integration (privacy-ux reference)
ShazamKit API and matching → stay here (shazamkit)

Now Playing + background audio:

Now Playing metadata/controls → stay here (now-playing)
Background audio mode / BGTaskScheduler → invoke axiom-integration (background-processing reference)

Photo library + privacy:

Photo picker (PHPicker, PhotosPicker) → stay here (photo-library) — no permissions needed
Full PHPhotoLibrary access → stay here (photo-library-ref) — limited access model
Privacy manifest for photo usage → invoke axiom-integration (privacy-ux reference)

Anti-Rationalization

Thought	Reality
"Camera capture is just AVCaptureSession setup"	Camera has interruption handlers, rotation, and threading requirements.
"I'll add haptics with a simple API call"	Haptic design has patterns for each interaction type matching HIG.
"ShazamKit is just SHSession + a delegate"	iOS 17+ has SHManagedSession which eliminates all AVAudioEngine boilerplate.
"Now Playing info is just setting metadata"	Remote commands, artwork handling, and state sync have 15+ gotchas.
"I'll use UIImagePickerController for photos"	PHPicker/PhotosPicker are the modern API — no permissions required.
