DualSenseWindowsManager now SwDeviceCreate's the pf_dualsense devnode per session
(SwDeviceClose on drop), matching the Linux UHID pad's lifecycle. It's best-effort:
SwDeviceCreate currently hits an unresolved E_INVALIDARG when a completion callback is
passed (an underscore in the enumerator name was a second cause, fixed by using
"punktfunk"), so on failure the host keeps the section + data plane and falls back to
an out-of-band devnode (installer/devgen) — see docs/windows-dualsense-scoping.md.
Add a `dualsense-windows-test` host CLI that drives the manager (create devnode + push
a frame + hold), used to validate the path. Live on the RTX box: the manager creates
the section + pushes report 0x01 and a devnode serves it to a HID read (b1=0xC0,
b8=0x28) — the host-side data plane works end to end.
cargo check + clippy -D warnings clean on x86_64-pc-windows-msvc.

A self-authored UMDF2 HID minidriver (packaging/windows/dualsense-driver) that
presents a virtual Sony DualSense (VID 054C/PID 0CE6) on Windows — adaptive
triggers / lightbar / rumble that ViGEm structurally cannot deliver.
Validated live on an RTX box (Win11 25H2, Secure Boot ON): the self-signed driver
loads, Steam recognizes it as a genuine DualSense, and a game's 0x02 output report
reaches the driver. The host<->driver channel is a named shared-memory section
(Global\pfds-shm-<idx>) the host creates and the driver maps from its timer: input
report 0x01 host->driver, output report 0x02 driver->host — input and output proven
both directions live. This bypasses hidclass, which gates both a custom device
interface and custom IOCTLs on the HID node, and UMDF has no control device.
Built in Rust on microsoft/windows-drivers-rs. The load wall was the PE
FORCE_INTEGRITY bit that wdk-build sets via /INTEGRITYCHECK (forces a CI-trusted
page-hash signature a self-signed cert cannot satisfy) — cleared post-build. See
packaging/windows/dualsense-driver/README.md for the build/sign/install recipe.
Deferred: SwDeviceCreate per-session device lifecycle; removing the inert in-driver
IOCTL-channel code; full on-glass session test.

A pass over the apollo-comparison backlog (re-verified against current code).
Lands four items end-to-end plus a Windows-DualSense scoping doc.
- #5/#92/#26 — GameStream paired-cert allow-list. tls.rs surfaces the verified
peer cert to handlers (serve_https + PeerCertFingerprint, now shared with the
mgmt API instead of duplicated); nvhttp gates /launch /resume /applist /cancel
on AppState.paired and reports a real PairStatus; save_paired writes atomically
(temp+rename). Closes the "mTLS accepts any client cert" hole. + regression test.
- #6/#51/#19/#22 — NVENC caps query -> reference-frame invalidation. nvenc.rs
query_caps probes nvEncGetEncodeCaps (max dims / 10-bit / custom-VBV / RFI),
rejecting over-range modes and degrading 10-bit->8-bit instead of an opaque
InvalidParam. New Encoder::invalidate_ref_frames (default false -> caller
keyframes); the Windows NVENC path implements real RFI (multi-ref DPB +
nvEncInvalidateRefFrames, dedup + IDR-on-overflow). control.rs decodes the
0x0301 lost-frame range (Apollo's IDX_INVALIDATE_REF_FRAMES) -> AppState.rfi_range
-> encode loop, falling back to a keyframe. NOTE: the Windows NVENC impl is
RTX-box/CI-pending (can't compile on Linux); adversarially reviewed vs the SDK.
- #43/#72 — media socket QoS + buffer growth. New punktfunk_core::transport::qos:
grow_socket_buffers (factored out the native plane's 32MB SO_SNDBUF growth so the
GameStream sockets reuse it) + set_media_qos (opt-in PUNKTFUNK_DSCP=1: DSCP CS5
video / CS6 audio + Linux SO_PRIORITY, Apollo's scheme). Wired into UdpTransport
and the GameStream video/audio sockets. Windows IP_TOS needs qWAVE (follow-up).
- #8/#45 — GameStream input injection off the ENet service thread. on_receive no
longer injects inline (a slow inject head-blocked ENet keepalive/retransmit); it
forwards to a dedicated injector thread. The hardened InjectorService moved from
punktfunk1 into crate::inject (shared by both planes) + a coalesce step that sums
adjacent relative-mouse/scroll deltas while preserving button/key/abs ordering.
Docs: re-verified apollo-comparison.md status (22 items already done/obsolete since
the snapshot) + windows-dualsense-scoping.md (ViGEm can't emulate a DualSense; real
DS5 on Windows needs a VHF virtual-HID driver — web-research pass pending).
fmt + clippy -D warnings clean; full workspace test suite green; no C-ABI/OpenAPI drift.
