Tested on .173: a WDA_EXCLUDEFROMCAPTURE window (affinity readback 0x11,
confirmed active) is pixel-identically visible in the punktfunk/1 stream
across no-flag / flag-set / flag-cleared phases — the flag makes no
difference to a present-tap capture. Replace the "untested, treat as
expected" note in the IDD-push residual list with the measured result,
and correct the framing: WDA visibility matches what a person at the
screen sees (it exceeds an ordinary capture tool, not the physical
viewer).
Add the matching public-facing paragraph to the security page covering
both asymmetries — WDA windows appear (same as a physical viewer), DRM
video is blanked (less than a physical viewer) — tied back to the page's
"a client sees what someone at the machine sees" model.

Frame ring (pf-vdisplay) and both gamepad SHM channels move off named Global\
objects (openable by any sibling LocalService) to UNNAMED sections/events whose
handles the host DuplicateHandles into the driver's verified WUDFHost with least
access — frame delivery over the SYSTEM+admins-only IOCTL_SET_FRAME_CHANNEL,
pads over a 32-byte named bootstrap mailbox (pid + handle value only, DoS-bounded;
HID minidrivers have no control device). Driver-validated pad_index kills
cross-pad redirects; v1↔v2 mixes fail closed with diagnosis logs on both sides.
Sibling-LocalService denial proven empirically (design/idd-push-security.md,
design/gamepad-channel-sealing.md).
Driver-side raw ops now live behind pf-umdf-util (checked shm accessors, the
forbid(unsafe_code) ChannelClient state machine, WDF request tokens) — the pad
drivers' logic is 100% safe Rust; whole drivers workspace clippy-gated in CI.
driver install --gamepad now sweeps SWD\punktfunk phantom devnodes: a re-created
SwDevice REVIVES the old devnode with its previously-bound driver (never
re-ranks), so an upgrade otherwise leaves the old driver serving — or, across
the v1→v2 fence, a dead pad (found live on the RTX box).
On-glass validated on the RTX 4090 box: frame path 7007 frames p50 2.06 ms
cross-machine; DualSense + XUSB "sealed pad channel mapped"/proto=2 attach via
both the test harness and a real streaming session; phantom-sweep repro.
