The pf-vdisplay driver now consumes the OS swap-chain so a virtual monitor is a usable display rather than a stalled one. Compiles + loads on-glass (no regression: adapter still inits, Status=OK); adversarially reviewed — no blockers, the leak/deadlock invariants preserved. - new swap_chain_processor.rs: a worker thread (MMCSS "Distribution") that binds the render D3D device (IddCxSwapChainSetDevice, single-borrow 60x@50ms retry) then drains the swap-chain (ReleaseAndAcquireBuffer2 -> FinishedProcessingFrame; E_PENDING waits 16ms on the surface event). NO frame publisher yet (STEP 6). RAII terminate+join Drop; the load-bearing top-of-loop terminate check (the oracle's reconnect-leak fix). Fixed a Rust-2021 disjoint- capture bug: `.0` field access bypassed the Sendable Send wrapper -> rebind the whole wrappers. - new direct_3d_device.rs: CreateDXGIFactory2 -> EnumAdapterByLuid(render LUID) -> D3D11CreateDevice; a DEVICE_POOL of one Arc<Direct3DDevice> per render LUID (the NVIDIA-UMD-worker-thread leak fix). - monitor.rs: MonitorObject gains swap_chain_processor; set/take helpers return it for the caller to drop OUTSIDE the MONITOR_MODES lock (dropping joins the worker — must never happen under the lock); remove_monitor/clear_all drop it before IddCxMonitorDeparture. - callbacks.rs: assign_swap_chain spawns the processor (pooled device per RenderAdapterLuid; WdfObjectDelete on D3D-init failure so the OS retries); unassign_swap_chain drops it. Fixed the stale `panic = "abort"` doc (workspace is unwind; the extern "C" boundary aborts on unwind). - Cargo.toml: windows 0.58 + thiserror (both already resolved in the driver lock). The 3 needed swap-chain DDIs were already wrapped in wdk-iddcx; their HRESULT-shaped NTSTATUS is classified by hand (hr>=0 success, 0x8000000A E_PENDING). - Also rustfmt'd the whole driver workspace (it had never been driver-fmt'd). Built via the ultracode flow: STEP-5 map workflow -> agent-implement -> box build (caught the Send-capture bug) -> adversarial-verify-agent -> deploy (loads). Session-1 on-glass validation (the drain loop servicing an ACTIVE monitor) is the next gate — assign_swap_chain only fires under an interactive session. Note for STEP 6: target_id_for_object uses the MONITOR_MODES handle lookup the oracle moved to a WDF context; revisit before target_id keys the shared frame ring.
