Crate rs_teststand_sys 

The low-level COM interop layer for the TestStand™ Engine API.

This is the only crate in the rs-teststand workspace where unsafe is permitted. Every unsafe block must carry a safety comment justifying it (enforced by clippy::undocumented_unsafe_blocks at deny level).

Scope: apartment (STA) initialization, late-bound IDispatch invocation, VARIANT conversion, HRESULT extraction, and the Win32 window and message facilities a COM apartment depends on (os). No TestStand™ semantics live here, the public rs-teststand crate builds the object model on top of the Dispatch seam.
