Headless Windows hosts (no dongle) stream an INVISIBLE cursor: with no
pointing device present win32k reports SM_MOUSEPRESENT=0 and DWM never
composites a pointer into the pf-vdisplay frame, even though SendInput
moves it. Keep ONE virtual HID mouse devnode alive for the host's
lifetime — the Sunshine/Parsec-class fix, zero client changes.
- pf-mouse: UMDF2 HID minidriver, one fixed identity (PF:MO 5046:4D4F,
obviously virtual, nothing fingerprints it), one 8-byte input report
(5 buttons + absolute 15-bit X/Y + wheel + AC-pan). Transport is the
sealed pad channel verbatim (Global\pfmouse-boot-0 mailbox + unnamed
MouseShm DATA section) so pf-umdf-util's audited layer serves it
unchanged; report delivery is event-driven (idle = no HID traffic).
- host: inject::mouse_windows — VirtualMouse (SwDeviceCreate'd devnode +
channel), ensure_resident() keeper thread started by every
InjectorService (process-wide, PUNKTFUNK_NO_VIRTUAL_MOUSE opts out),
vmouse-spike on-glass validation (cursor sweep via HID reports).
- proto: mouse module (magic, boot-name, identity, report layout,
unit-tested input_report packing).
- SwDeviceProfile grows container_tag so the mouse's ContainerId family
(PFMO) never groups with a pad's (PFDS) in the Devices UI.
- packaging: pf-mouse rides the gamepad-driver build + install pipeline
(build-gamepad-drivers.ps1, windows-drivers.yml, driver install
--gamepad picks up every staged .inf).
On-glass validated on winbox: devnode + HID child bind, SM_MOUSEPRESENT=1
with no physical mouse, cursor sweeps via HID reports (vmouse-spike).
This work was implemented in a parallel session; committed here as the
build prerequisite for the HID compose kick that follows.
