No source file, test, or entry point is named in the issue. Start by reviewing the Xiaomi adapter and the reported secure/security_pc_secure_protect_mode_key values, then compare the linked forum post and macro files. Done means the maintainer can reproduce the mapping and confirm whether support can be enabled for this device.
