Native ARM64 helper for nxnative Easy's experimental integrated iPhone/iPad sign/install/refresh flow. See architecture, security boundary and validation.

It uses isideload 0.5.0 (MIT), with the included exact-identifier patch, and idevice 0.1.68 (MIT). Signing dependencies are pinned in Cargo.lock and their notices/source URLs are bundled by the desktop builder. No Sideloadly code, binary, icon or proprietary resource is included.

The newline JSON protocol is private stdin/stdout. It accepts devices, installed_apps, login, restore, code, resend, send_to_devices, sms, install, logout and quit. Authentication requests must never be logged or passed in argv/environment variables. Protocol errors are redacted. Tests use synthetic credentials and never sign/install on a user's device.

The helper has no uninstall operation and never automatically revokes certificates. RomFS access is restricted to /Documents/romfs and reserved transfer journals; it does not read or write save roots. Physical-device and real-account validation is still required before treating this as a tested Sideloadly replacement.
