Author the custom virtual HID gamepad that replaces vJoy, and pin its wire format on both sides. Builds clean to RioGamepad.sys against the EWDK (KMDF 1.15 + VHF, x64, warnings-as-errors). driver/RioGamepad/: - ReportDescriptor.h: 6x16-bit axes (X,Y,Z,Rx,Ry,Rz), one 4-direction hat with null state, and 96 buttons — the legacy vJoy layout. 25-byte input report. - Device.c/Driver.c: KMDF root-enumerated device that creates the VHF virtual HID device (VhfCreate in DeviceAdd, VhfStart in D0Entry, VhfDelete on cleanup) and exposes a device interface + IOCTL_RIO_SUBMIT_REPORT that forwards the caller's report bytes to VhfReadReportSubmit. Thin relay: no report logic in the kernel. - Public.h: device-interface GUID, IOCTL, and the report byte layout shared with the C# client. RioGamepad.inf + build.cmd (EWDK build, catalog/sign disabled). src/RioJoy.Core/Hid/RioHidReport.cs: packs AxisOutputs + hat + 96 buttons into the exact 25-byte report (LE axes, hat nibble with 0x0F=centered, button bitmap). 13 new xUnit tests (136 total). Remaining (deploy-side): test-sign + pnputil install + verify in joy.cpl, and wire the real DeviceIoControl feeder sink (replacing NullJoystickSink). The EWDK's in-build catalog task (DrvCat) can't load Microsoft.Kits.Logger on this image, so the .cat is produced with inf2cat/signtool at install time instead.
