Module impls 

Production (Sys) implementations of the device traits.

Each Sys* struct wraps the corresponding free functions in the device modules. Construct once at startup and pass &dyn Trait to code that needs testable device access.

Production battery: reads /sys/class/power_supply/*/capacity.

SysBluetooth

Production bluetooth: DBus calls to bluez / mtk.bluedroid.

SysFramebuffer

Production framebuffer: wraps Fb (mmap’d /dev/fb0 + MXCFB refresh).

SysFrontlight

Production frontlight: reads/writes real sysfs brightness files.

SysSystemControl

Production system control: kernel suspend via /sys/power/state, wall-clock via date command.

SysWifi

Production wifi: reads /sys/class/net/wlan0/operstate.
