Detailed Description

Singleton shadow state for the host-MSC driver.

Shared across the ra8_usb_hmsc split. The lifecycle / command-path TU (ra8_usb_hmsc.c) and the enumeration-ladder TU (ra8_usb_hmsc_enum.c) both read and write this object, so it remains a single instance with the type declared here in the shared private header.

Invariant: attached is only true after a completed enumeration pass.

Note: Module-private to libs/ra8_hal/src; not part of the public surface.

Since: 0.1.0
