Graduate the proven iddcx_rt.rs dispatch into wdk-iddcx + add the full DDI set the
pf-vdisplay driver needs: DeviceInitConfig/Initialize, AdapterInitAsync,
MonitorCreate/Arrival/Departure, AdapterSetRenderAdapter (void-returning DDI — its
PFN returns ()), SwapChainSetDevice/ReleaseAndAcquireBuffer2/FinishedProcessingFrame.
One dispatch macro pins each (_IDDFUNCENUM index, PFN_* type) pair exactly once
(the only place table dispatch can be UB). Box-compiles green; IddCxStub link gets
validated when pf-vdisplay (cdylib) consumes it in STEP 2.

M1 step 2 begins. Add the wdk-iddcx (lib, re-exports wdk_sys::iddcx) + pf-vdisplay
(cdylib) workspace members. pf-vdisplay STEP 0 = DriverEntry + WdfDeviceCreate
skeleton + a #[used] _std_link_gate forcing std::thread + OwnedHandle to link, so
the build proves the std surface resolves under the wdk-build UMDF link settings
(kernel32 is /NODEFAULTLIB - std must come via OneCoreUAP). If std fails to link
here, the SwapChainProcessor worker-thread design needs a CreateThread shim before
any callback work (port-plan critique gap #9).

Port-plan critique #1: convert "the (?i).*iddcx.* allowlist may miss a symbol the
full driver needs" from a box-only surprise into a CI compile gate. New
wdk-probe/src/iddcx_surface_assert.rs size_of-asserts every *2/HDR struct
(IDDCX_TARGET_MODE2/PATH2/METADATA2, IDARG_*RELEASEANDACQUIREBUFFER2 — these embed
DISPLAYCONFIG_*/LUID, which RESOLVE from crate::types: no allowlist gap),
None-asserts all 14 inbound PFN_IDD_CX_* callbacks, and confirms the .Size
machinery (IddStructures/IddStructureCount/IddClientVersionHigherThanFramework/
_IDDSTRUCTENUM::INDEX_*) + the FP16/HIGH_COLOR_SPACE flags. Box-built green; the
wdk-sys binding is proven complete for the ENTIRE driver, not just init. Also
silence the bindgen naming lints in the iddcx module.

First USE of the iddcx binding: a minimal table-dispatch (src/iddcx_rt.rs) over
wdk_sys::iddcx — IddFunctions[_IDDFUNCENUM::<Name>TableIndex] cast to PFN_*,
IddDriverGlobals as implicit arg 1 (the WDF model; ModuleConsts i32 index, not the
oracle NewType .0). The probe EvtDeviceAdd now calls IddCxDeviceInitConfig →
WdfDeviceCreate → IddCxDeviceInitialize → IddCxAdapterInitAsync, exports
IddMinimumVersionRequired=4, and build.rs links IddCxStub (globbed from the SDK
Lib dir that ships iddcx). CI gate = compile + link IddCxStub.

Last UINT errors were all `pub type Type = UINT;` inside bindgen enum modules
(pub mod _DXGI_X {..}) — the top-level UINT alias cannot reach nested modules. C++
parsing made bindgen keep the UINT typedef as the enum underlying repr (C mode
emits a primitive). translate_enum_integer_types(true) emits native u32 reprs, so
the enum modules are self-contained; struct-field UINT stays covered by the
src/iddcx.rs alias.

Last iddcx type gaps: (1) DXGI enum newtypes are `pub use self::_DXGI_X::Type as
DXGI_X` — the `_DXGI_X` module needs allowlisting too (broaden DXGI_.* to
_?DXGI_.*, matching the OPM fix); (2) UINT bindgen raw_line landed in a scope the
bindings cannot see — define `pub type UINT` directly in src/iddcx.rs next to
`use crate::types::*` instead.

DXGI resolved. Remaining iddcx type gaps: OPM typedefs need their _OPM_* struct
tags too (recursively(false) drops them), D3DCOLORVALUE (an OPM field), and UINT
(unsigned int — absent from crate::types, and allowlist_type does not emit bare
primitive aliases). Broaden to _?OPM_.* + _?D3DCOLORVALUE and raw_line the UINT
alias.

The iddcx bindgen now SUCCEEDS (C++ fix). Generated module had 38 unresolved-type
errors — a bounded set wdk-sys does not bindgen: UINT, DXGI_FORMAT,
DXGI_COLOR_SPACE_TYPE, IDXGIDevice/Resource, 6 OPM_* types. No WDF type is
missing, so the crate::types sharing (type-identity) holds. Allowlist those
families so they emit locally in iddcx.rs (non-conflicting — absent from
crate::types), keeping allowlist_recursively(false).

Direct clang test on the box proved IddCx.h parses with 0 errors as C++ but fails
as C (wdk_default has no --language=c++) — the IDARG_* typedef names hit "must use
struct tag" in C mode. Fix generate_iddcx: --language=c++ + keep -DIDD_STUB +
allowlist_recursively(false) + full codegen, so it emits ONLY IddCx items
(structs, the IddFunctions table enums, DDI fn-ptr typedefs) and references
WDF/Win/DXGI types from wdk-sys via `use crate::types::*` (no re-emission, no
blocklist). Reverted the ENABLED_API_SUBSETS Iddcx entry (it wrongly pulled
IddCx into the C-mode constants/types passes).

The iddcx bindgen failed with IddCxFuncEnum.h "IDDCX_VERSION_MAJOR is not defined"
+ a cascade of "must use struct tag" on IDARG_* types — NOT the feared #515
header conflict (IddCx parsed fine alongside Base+Wdf). IddCx.h needs STUB mode
(function-table dispatch) for the version macros to resolve; add -DIDD_STUB to
generate_iddcx, matching the wdf-umdf oracle. Deliberately NOT WDF_STUB (wdk-sys
parses wdf non-stubbed; desyncing only here would break WDF type-identity).

Vendor the published, self-contained windows-drivers-rs 0.5.1 crates
(wdk-build, wdk-sys) under vendor/ and add a first-class ApiSubset::Iddcx that
bindgens iddcx/1.10/IddCx.h in an extra pass reusing bindgen::Builder::wdk_default
(allowlist_file (?i).*iddcx.* — emits only IddCx items; WDF/DXGI types resolve to
the shared base/wdf bindings, type-identity by construction). Mirrors the existing
gpio/hid/spb subsets exactly: wdk-build gets the enum variant + iddcx_headers()
(UMDF-only), wdk-sys gets generate_iddcx + the iddcx feature + pub mod iddcx.
[patch.crates-io] redirects all wdk-sys/wdk-build (incl. wdk 0.4.1 transitive) to
the patched copies. wdk-probe enables the iddcx feature.
MAKE-OR-BREAK: does IddCx.h bindgen in wdk-sys config without a header conflict
(issue #515) + does the generated module compile (type-identity)? CI answers it.

wdk-build errored StaticCrtNotEnabled + the generated wdk-sys layout asserts
overflowed (E0080) — UMDF needs the static CRT. Add the canonical
windows-drivers-rs .cargo/config.toml: explicit target = x86_64-pc-windows-msvc
(separates host proc-macros, which stay dynamic-CRT, from the driver) +
target-feature=+crt-static scoped to that target. DLL now under the triple subdir.
The WDK bindgen itself now runs (it generated out/types.rs) — this is the last
build-config layer before the /INTEGRITYCHECK verdict.

wdk-sys build script: "missing field driver-model" deserializing
workspace_metadata[wdk] — a workspace build reads the model from the WORKSPACE
metadata, not the package. Set [workspace.metadata.wdk.driver-model] = UMDF 2.31
(all our drivers are UMDF 2.x incl. pf-vdisplay IddCx). Past the Cargo.lock fix.

wdk-build requires a Cargo.lock next to the top-level Cargo.toml (it panics
otherwise — "a Cargo.lock file should exist..."). Generated on Linux
(resolution is platform-independent; only the build needs the WDK). Everything
else compiled on the runner — pf-vdisplay-proto, bindgen, wdk-build/sys/macros.

Stand up packaging/windows/drivers/ — the unified driver workspace on crates.io
windows-drivers-rs (wdk 0.4.1 / wdk-sys + wdk-build 0.5.1), retiring the dev-box
../../crates/wdk* path-deps. First member: wdk-probe, the smallest UMDF2 driver
(DriverEntry -> WdfDriverCreate -> EvtDeviceAdd -> WdfDeviceCreate) that
force-links the shared pf-vdisplay-proto ABI crate. It validates on the runner:
wdk-sys bindgen + WDF stub link against the WDK + LLVM, the cross-workspace
no_std proto path-dep, and the produced DLL's PE FORCE_INTEGRITY bit.
windows-drivers.yml gains a driver-build job: cargo build -p wdk-probe (pinning
Version_Number=10.0.26100.0) + a PE inspection that prints whether /INTEGRITYCHECK
is set — the M0 self-signed-load question.
