Observed on a production-fused A16 Bionic devices (e.g., iPhone 14 Pro Max),the internal debug pathways activating under stock iOS (debug = 0x0, dev-fused = 0). SecureROM, firmware, and co-processors all exhibit debug behavior without jailbreak, tampering, or provisioning profiles.
This violates Apple’s hardware trust model and exposes internal diagnostics meant for development silicon.
