enricobuehler 0da9d8ec10 fix(windows): IDD-push audit highs — keyed-mutex timeout, two per-frame leaks, IDD_PUSH knob, pooled-device threading
Five verified findings from the IDD-push/pf-vdisplay deep audit:

- Keyed-mutex acquire (BOTH endpoints): AcquireSync returns WAIT_TIMEOUT
  (0x102) / WAIT_ABANDONED (0x80) as SUCCESS-severity HRESULTs, which the
  windows-rs Result wrapper erases — a busy slot read as "acquired", so
  driver and host could race the same ring texture (torn frames) and the
  designed busy-skip backpressure was dead code. Both sides now classify
  the raw vtable HRESULT; WAIT_ABANDONED counts as acquired (ownership
  transfers — refusing it would wedge the slot forever).
- Host SDR hot path leaked one ID3D11VideoProcessorInputView per converted
  frame: the D3D11_VIDEO_PROCESSOR_STREAM ManuallyDrop field suppressed the
  release after VideoProcessorBlt. Released by hand now, success or not.
- Driver leaked IddCx's per-acquire surface reference (from_raw_borrowed on
  a TRANSFERRED reference — the MS sample Attach/Reset's it): the swap-chain
  surface set survived swap-chain destruction, the likely true root cause of
  the ~50 MB-per-reconnect VRAM loss that device pooling only mitigated.
  Now adopted via from_raw (publisher or not) and dropped pre-Finished.
- PUNKTFUNK_IDD_PUSH removed: capture is unconditionally IDD-push, but the
  vdisplay manager still gated the lingering-monitor preempt (and render
  pin) on the knob, whose default was OFF — dev/CLI runs reused a lingering
  monitor whose IddCx swap-chain is dead (black reconnect). The preempt and
  the render-GPU pin are now unconditional; host.env comments no longer
  promise the removed DDA/WGC fallback.
- Driver D3D device: dropped D3D11_CREATE_DEVICE_SINGLETHREADED (unsound
  since DEVICE_POOL shares one device across processors) and the pooled
  immediate context is now SetMultithreadProtected — two concurrent
  monitors' workers otherwise race an unlocked context (UB in the UMD).

No wire-contract change (pf-driver-proto untouched); the driver fixes take
effect on the next pf-vdisplay redeploy.

punktfunk-docs

The punktfunk documentation site: Fumadocs on TanStack Start (Vite + Nitro/bun preset).

Content lives in content/docs/ as .md/.mdx. This site is the source of truth for the user-facing guides; repo-internal design rationale lives in ../design/.

API reference

/api renders the host's management REST API as an interactive Scalar reference (linked from the top nav, the docs sidebar, and the landing page). It reads public/openapi.json — a snapshot of the repo's generated spec. Refresh it after a management-API change:

# from the repo root — regenerate the spec, then copy the snapshot in:
cargo run -p punktfunk-host -- openapi > api/openapi.json
cp api/openapi.json docs-site/public/openapi.json

Develop

bun install
bun run dev        # http://localhost:3001  (docs at /docs)

Build & serve

bun run build
bun run start      # serves .output/ via Bun
