create_swdevice now succeeds. The two requirements (each E_INVALIDARG otherwise): the
enumerator name must have no underscore (use "punktfunk"), and the completion callback is
mandatory (the docs mark pCallback [in], not optional -- NULL is rejected). Back on the
typed windows-rs SwDeviceCreate (a raw-FFI diagnosis confirmed it's the OS, not the
binding), parameterized by pad index (instance pf_pad_<index>), waiting on the callback.
Per-session device: created on connect, SwDeviceClose'd on drop -- no leftovers, no phantom.
Live-verified on the RTX box: device materializes, the UMDF driver binds, SDL3 identifies it
as a PS5 ("DualSense Wireless Controller"), input flows; removed on disconnect. The
dualsense-windows-test CLI now cycles input + prints any 0x02 feedback for diagnosis.

cargo audit fails on the rsa "Marvin Attack" advisory, which has NO fixed release
(the constant-time rewrite is still unreleased upstream) and rsa is required for
GameStream/Moonlight pairing. The attack targets RSA *decryption* (PKCS#1 v1.5
padding oracle); the host uses rsa ONLY for PKCS#1 v1.5 signing/verifying
(gamestream/cert.rs + pairing.rs), never for decryption, so the vulnerable path is
not exercised. Add the documented .cargo/audit.toml ignore with the justification.
The 3 unmaintained warnings (audiopus_sys / paste / rustls-pemfile) are left visible
on purpose — `cargo audit` does not fail on them, and they carry a maintenance signal.

The Windows host was NVIDIA-only (NVENC) with an openh264 software fallback. Add
AMD AMF and Intel QSV via libavcodec — the Windows analogue of the Linux VAAPI
backend — so one installer serves all three GPU vendors.
- encode/ffmpeg_win.rs: new WinVendor{Amf,Qsv} encoder. System-memory NV12/P010
readback (default, robust) + opt-in zero-copy D3D11 (PUNKTFUNK_ZEROCOPY: shares
the capturer's ID3D11Device; AMF takes AV_PIX_FMT_D3D11, QSV derives a QSV frames
ctx and maps) with a system fallback for the format-group mismatch the capturer's
video-processor fallback can produce. HDR Main10 (P010 + BT.2020/PQ VUI; an
Rgb10a2->P010 swscale covers the shader fallback).
- encode.rs: Codec::amf_name/qsv_name; open_video + windows_resolved_backend()
resolve PUNKTFUNK_ENCODER=auto|nvenc|amf|qsv|sw via a DXGI adapter VendorId probe.
- capture/dxgi.rs: gpu_mode mirrors the resolved backend (D3D11 NV12/P010 for AMF/QSV).
- gamestream/serverinfo.rs: GPU-aware codec advertisement (windows_codec_support;
AV1 gated to RDNA3+/Arc, like the VAAPI path).
- Cargo.toml: amf-qsv feature (optional ffmpeg-next in the windows target block).
- CI/installer: windows-host.yml sets FFMPEG_DIR + builds --features nvenc,amf-qsv;
the Inno installer bundles the FFmpeg DLLs; host.env default nvenc -> auto.
CI-green target; AMF/QSV not yet on-glass validated (no AMD/Intel Windows box in the
lab) — NVENC stays live-validated. An adversarial-review pass caught + fixed real
FFI bugs (AV_PIX_FMT_P010 is a macro -> P010LE; windows-rs 0.62 GetImmediateContext/
GetDesc1 return Result; AV_HWFRAME_MAP_* is a bindgen enum with no BitOr).

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.

The host<->driver channel is the shared-memory section (hidclass blocks the device
stack and UMDF has no control device), so the first-attempt in-driver IOCTL channel
never fired. Remove it: the custom device interface, IOCTL_PFDS_SET_INPUT/GET_OUTPUT,
the output queue, and the on_set_input/complete_one_read/deliver_output helpers. The
driver keeps the HID handshake, the 8ms read timer fed from the shared section, and
on_output_report publishing the game's 0x02 to the section. Rebuilt + reloaded + the
channel still verifies both directions live on the RTX box.
Also list `pf_dualsense` as a second hardware id (alongside `root\pf_dualsense`) so the
host's SwDeviceCreate'd software device binds the same driver as a devgen one.

Wire the Windows UMDF DualSense driver into the host as a real pad backend, so a
client that requests a DualSense gets a genuine one on a Windows host (instead of
folding to Xbox 360).
- Extract the transport-independent DualSense contract (DsState + from_gamepad,
serialize_state, parse_ds_output, DUALSENSE_RDESC, feature blobs, DS_* consts)
out of the Linux-only UHID backend into inject/dualsense_proto.rs, shared by both
platforms; dualsense.rs is now just the /dev/uhid plumbing.
- Add inject/dualsense_windows.rs: DualSenseWindowsManager mirroring the Linux
DualSenseManager (same new/handle/apply_rich/pump/heartbeat surface) over a
DsWinPad that creates the Global\pfds-shm-<idx> section (CreateFileMappingW +
SDDL D:(A;;GA;;;WD) so WUDFHost can open it), writes serialize_state -> input
slot, polls output_seq -> parse_ds_output -> rumble/hidout callbacks.
- Un-gate the seam: PadBackend::DualSenseWindows arm; pick_gamepad gains a
windows flag (DualSense honored on linux||windows; DS4/Xbox One stay Linux-only).
Verified: Linux cargo test gamepad_resolution_precedence + clippy clean; Windows
cargo check + clippy -D warnings clean (on the RTX box). Device lifecycle still
uses an out-of-band devnode (devgen/installer); SwDeviceCreate per session is next.

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.

Scalar's /api reference injects a *global* `body { background-color:
var(--scalar-background-1) }` (via its linked stylesheet + a runtime
<style id=scalar-style>) that TanStack doesn't remove on a client-side route
change. After navigating /api -> /docs without a reload, that rule kept
painting the docs body: Scalar's stock gray (#0f0f0f) while .dark-mode lingered
on <body>, or transparent once the class was gone. A hard reload was fine
because the stylesheet was never loaded there.
Fix: give --scalar-background-1 a global fallback = --color-fd-background so any
non-API page paints its own surface while Scalar's sheet lingers; /api itself
overrides it via the higher-specificity body.{dark,light}-mode rule. Also strip
the leftover #scalar-style/#scalar-refs nodes and body mode-class when /api
unmounts so the DOM matches a fresh load. Verified light + dark via headless
CDP: post-nav docs body now equals a fresh reload (#141019 / #f0ebff).
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Scalar puts .light-mode/.dark-mode on document.body and renders customCss
*before* its built-in theme preset in the same <style> tag, so a bare
.dark-mode override loses at equal specificity and the stock #0f0f0f gray
showed through. Scope the palette to body.{dark,light}-mode (0,1,1) so it beats
both the linked base sheet and the in-component preset, and add a full
light-lavender palette to match the docs light surface.
Drive Scalar's darkMode from the resolved Fumadocs theme (next-themes) instead
of hard-locking it on, so toggling the docs theme switch flips the API
reference too; the React wrapper's updateConfiguration effect live-swaps the
body mode class.

A push to main publishes canary builds to canary channels (fast iteration,
unchanged); a single vX.Y.Z tag releases every platform at one version to the
stable channels and attaches all artifacts (.deb/.rpm/.msix/.apk/.aab/.dmg +
flatpak/decky/host-installer) to one Gitea Release. Collapses the
host-v*/win-v*/host-win-v* tag namespaces into v* — the channel split makes the
version-shadow bug structurally impossible (canary and stable are separate repos,
never a shared version line).
- scripts/ci/gitea-release.{sh,ps1}: one idempotent release helper
(create-or-fetch + delete-before-upload), replacing 3 copy-pasted inline blocks
and fixing their latent 409-on-reupload bug; prerelease flag auto-derived from
the tag (an -rc tag won't shadow "Latest")
- channels: apt canary/stable distributions; rpm *-canary/base groups; flatpak
canary/stable OSTree branches + a 2nd .Canary.flatpakref; generic-registry
canary/ vs latest/ aliases; Play internal/alpha; Apple TestFlight vs notarized DMG
- android versionName threaded through gradle (versionCode stays run_number);
Apple canary = TestFlight-only (no DMG/tvOS); canary base bumped to 0.3.0
- docs: new docs-site channels.md (subscribe table + cut-a-release runbook +
box migration), refreshed ci.md workflow table + packaging READMEs

Extends virtual-controller support beyond Xbox 360 + DualSense. Goal: a
physical Xbox One or PS4 pad on the client gets a near-native matching virtual
pad on the host, auto-resolved from the controller type.
Protocol/core:
- GamepadPref gains XboxOne (wire 3) + DualShock4 (wire 4); to_u8/from_u8/
from_name/as_str + C ABI PUNKTFUNK_GAMEPAD_XBOXONE/_DUALSHOCK4 constants
(compile-time guard ties them to the enum). Single-byte wire form is
unchanged, so it's forward-compatible (older peers degrade to Auto).
Host (Linux):
- New UHID DualShock 4 backend (inject/dualshock4.rs) bound by hid-playstation:
lightbar, touchpad, motion, rumble — DualSense minus adaptive triggers /
player LEDs / mute. Reuses the DualSense pure state + button mapping; only the
report byte layout, the real-DS4 HID descriptor, the GET_REPORT handshake
(0x12 MAC mandatory; 0x02 calibration; 0xa3 firmware) and the touchpad
resolution (1920x942) differ. Touchpad/motion ride the existing 0xCC plane,
lightbar the 0xCD Led plane (deduped); rumble the universal 0xCA plane.
- Xbox One/Series is the uinput Xbox-360 backend parameterized with the One S
USB identity (045e:02ea) for matching glyphs — XInput-identical otherwise.
- PadBackend dispatch + resolver handle both; off Linux the UHID pads and
One/Series fold into Xbox 360. Windows-host DS4 (ViGEm) deferred.
Clients (auto-resolve physical pad -> virtual type, plus manual settings):
- Linux/Windows (SDL3): SDL_GAMEPAD_TYPE_PS4 -> DualShock 4, _XBOXONE ->
Xbox One; PadInfo carries the resolved pref; DS4 touchpad/motion capture +
lightbar already type-agnostic. Linux settings combo + label updated.
- Apple (GameController): GCDualShockGamepad/GCXboxGamepad detection, DS4
touchpad capture, settings picker entries.
- Android (Kotlin): InputDevice VID/PID auto-detect (matching the other
clients) + settings entries.
- probe: --gamepad help/aliases.
Also hardens the Android JNI boundary: wrap the teardown + poll-thread shims in
catch_unwind so a panic degrades to a logged no-op instead of aborting the app.

- Dashboard session card: the header stacks the title above the action buttons
on narrow screens (flex-col -> sm:flex-row) and the button group wraps
(flex-wrap), so "Request IDR" / "Stop session" no longer overflow the card.
- Mobile bottom nav: give each label a fixed two-line-tall centered box so a
1- or 2-line label (labels vary by locale) keeps every tab icon at the same
height.

@scalar/api-reference-react@0.9.47's entry imports createApiReference but does
NOT import its own style.css (nor inject it at runtime), so /api rendered with
no Scalar CSS at all. Import the sheet as a route-scoped <link> (?url +
head.links, same pattern as the root app.css) so it loads for SSR + the
client-side Vue mount. The brand customCss still themes on top.

- console: remove @unom/ui's specular "material" gloss (drop UnomProviders +
the material.css import) so components render flat like the marketing site;
the violet brand + Geist stay.
- mobile bottom tab bar: center the labels (w-full text-center, leading-tight)
and even out the per-tab layout.
- docs /api: roll the punktfunk dark-violet palette across the whole Scalar
reference (surfaces/text/sidebar/links/buttons/method colours via the full
--scalar-* token set), locked to dark (hideDarkModeToggle).

Move the management console (web/) off shadcn/ui to the shared @unom/ui
design system the marketing site + docs are built on, on the punktfunk
violet brand over dark chrome:
- Add @unom/ui/@unom/style/motion/radix-ui/zod + Geist; web/.npmrc maps the
@unom scope (packages are public-read, so CI needs no npm auth).
- styles.css: one dark-violet palette (#141019/#1c1530, brand #6c5bf3 ->
#a79ff8) exposed under BOTH the shadcn token names the routes use and
@unom/ui's contract, so routes + components both resolve; pulls in
@unom/ui's material gloss + easings.
- components/ui/* now back onto @unom/ui (AnimatedButton/InputText/Label/
AnimatedCard); brand-mark/wordmark/logo replace the generic Radio icon in
the shell + login.
- MaterialProvider (specular gloss) at the root. No UI sounds, like the site.
docs-site: new /api route renders the host management REST API as an
interactive Scalar reference (reads public/openapi.json, a snapshot of
docs/api/openapi.json), branded violet and linked from the top nav, the
docs sidebar, the landing page, and host-cli.md.

- Rename steam-deck-host.md → steamos-host.md (nav + install table updated).
- Lead with the rationale: SteamOS host support targets the upcoming Steam
Machine; the Steam Deck is the SteamOS device validated against today.
- Soften the WiFi note: ~250 Mbps was our testing on one device/network,
not a universal ceiling — other SteamOS hardware/drivers/bands may do more.
- Generalize Deck-specific language to SteamOS devices throughout.
- Document --no-gamestream (secure native-only) + GameStream-compat caveat.
- decky README: drop stale `serve --native` (now just `serve`).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Completes the GameStream-opt-in posture (0de648f) on the SteamOS path: the installer keeps
Moonlight compat on by default (`serve --gamestream`, the Deck commonly streams to Moonlight),
but `--no-gamestream` now installs a secure native-only host with no GameStream on-path surface
(plain-HTTP pairing / legacy GCM nonce reuse — security-review #5/#9; native clients only).
Documented in the installer --help; the SteamOS host doc references it.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Follows the security audit (#5/#9): the GameStream-compat plane carries inherent on-path weaknesses
that can't be fixed on the wire without breaking stock Moonlight — its pairing runs over plain HTTP
(#9, MITM-able during the pairing window) and its legacy control encryption can reuse GCM nonces (#5,
a passive eavesdropper can recover/forge input). The native punktfunk/1 plane (SPAKE2 PIN pairing +
per-direction AEAD nonces) has neither. So flip the default to secure-by-default:
- `serve` → native punktfunk/1 plane + management API ONLY (no GameStream surface).
- `serve --gamestream` → ALSO the GameStream/Moonlight-compat planes (nvhttp pairing, RTSP, ENet
control, _nvstream mDNS). Opt-in, logged with a trusted-LAN caveat. `--moonlight` is an alias.
- The native plane is now ALWAYS on in `serve` (`--native` is a kept-for-compat no-op); the unified
GameStream+native host is `serve --gamestream`.
`gamestream::serve` gates the GameStream spawns (nvhttp/rtsp/control/mdns) on the flag; the native
plane + mgmt + native-pairing handle always run.
To avoid silently regressing validated Moonlight deployments, the explicit deployment configs PRESERVE
Moonlight via `--gamestream` (each documents dropping it for a secure native-only host): the Linux
systemd unit, the Steam Deck installer, and the Windows service default (DEFAULT_HOST_CMD). The bare
`serve` default (new/manual use) is secure.
Docs swept to match (host-cli, moonlight, quickstart, install, packaging READMEs, CLAUDE.md, README,
…): Moonlight setup now instructs `--gamestream`; native/console refs use bare `serve`. OpenAPI
regenerated (a stale "run `serve --native`" string). fmt + clippy clean; 94 host tests green.

Addresses the lower-severity findings from docs/security-review.md (#4-#12). Each fix was
adversarially re-reviewed (5-agent pass); two review catches folded in (the Apple client's
GET /library cert path; an RTSP header-cap bypass + a spawn-panic counter leak).
- #4 [low] mgmt mTLS-paired-cert no longer grants full admin. A paired STREAMING cert authorizes
only a read-only allowlist (GET /host,/compositors,/status,/clients,/native/clients,/library);
every state-changing route and every PIN-exposing route (/pair, /native/pair) requires the
operator's bearer token. New cert_auth_is_a_read_only_allowlist test. (/library kept on the
allowlist — the native clients browse it cert-only; its mutations stay token-only.)
- #6 [low] RTSP pre-auth DoS bounds: a concurrent-connection cap (RAII slot guard), a per-read
timeout (slow-loris), and Content-Length/header/message size caps — closing an unauthenticated
slow-loris / memory-growth / thread-exhaustion vector on TCP 48010.
- #11 [info] A FEC reconstruction failure is now a counted drop (discard the block, keep the
session) instead of being stream-fatal — a lossy link can't be torn down by one bad block.
- #10 [info] Fixed ALPN ("pkf1") on both native QUIC endpoints (defense-in-depth; a deliberate
coordinated client+host upgrade — a new host rejects an ALPN-less old client).
- #8 [info] Constant-time GameStream pairing phase-4 hash compare (crypto::ct_eq).
- #7 [low] New VirtualDisplay::set_launch_command carries the launch command per-session on the
GameStream path (no process-global env stomp under concurrent sessions); native path keeps the
env under today's single-session model (documented; plumb per-session with concurrent sessions).
- #5 [low] Legacy GameStream GCM nonce reuse: documented as inherent to Nvidia's old-style control
encryption (Apollo/Moonlight identical; key is client-known) — unfixable on the legacy wire; the
real fix is V2 control-encryption negotiation. Code comment at control.rs.
- #9 [info] GameStream plain-HTTP pairing: documented (inherent to GFE compat; use punktfunk/1).
- #12 [low] Web global NODE_TLS_REJECT_UNAUTHORIZED: fix designed (undici dispatcher scoped to the
loopback mgmt fetch) but DEFERRED — needs `bun add undici` in the web build env; reverted to keep
the web working. Latent-only (the loopback mgmt fetch is the console's only outbound TLS).
fmt + clippy -D warnings clean; 94 host + core tests green; no C-ABI/OpenAPI drift. (The HDR
Steps 1-2 client work in the tree is the user's parallel WIP — deliberately NOT included here.)
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Continues docs/hdr-pipeline-plan.md. Steps 0/1 + Step 2 (Windows/Android) already
landed in ffae2a3; this is Step 2 (Apple) + Step 3 (all clients). Client-only — no
core/host/ABI change (the 0xCE/next_hdr_meta/color_info surfaces shipped in Step 0).
Step 2 — clients APPLY the host's HDR metadata (each remaps from the wire form: ST.2086
G,B,R order, mastering luminance in 0.0001 cd/m2):
- Apple: connect via punktfunk_connect_ex5 (resurrects the previously-dead HDR pipeline);
nextHdrMeta/colorInfo wrappers + HdrMeta SEI-blob builders; the pump drains nextHdrMeta
-> VideoDecoder.setHdrMeta -> CVBufferSetAttachment of MasteringDisplayColorVolume (24B
BE) + ContentLightLevelInfo (4B BE) on each HDR pixel buffer (correct for the
itur_2100_PQ layer; CAEDRMetadata avoided as ambiguous there).
Step 3 — capability-gate: advertise HDR caps ONLY when the display can present it, so an
SDR display gets a proper BT.709 stream instead of PQ it would mis-tone-map; an HDR
display self-tone-maps from the Step-1/2 mastering metadata.
- Windows: present::display_supports_hdr() (DXGI any IDXGIOutput6 colour space == G2084),
ANDed with the user HDR setting in session.rs; logs the SDR drop.
- Apple: NSScreen.maximumExtendedDynamicRangeColorComponentValue>1 (macOS) /
UIScreen.main.potentialEDRHeadroom>1 (iOS) in SessionModel.
- Android: Settings.displaySupportsHdr (Display.getHdrCapabilities HDR10/HDR10+) passed
through a new hdr_enabled jboolean on nativeConnect; session.rs gates the caps.
Validation: Android native (incl. the jboolean gate) builds + clippy clean via cargo-ndk;
fmt clean. Windows (MSVC), Apple (Swift) and the Kotlin side are CI/on-glass validated —
not compilable on the Linux dev box. Deferred to the RTX box: mid-session Reconfigure
SDR-downgrade on monitor move, and confirming the host emits SDR for an SDR client off an
HDR desktop.

Two strands, entangled in punktfunk1.rs, committed together (one builds-green tree).
HDR pipeline Step 0 — glass-to-glass colour-metadata transport (docs/hdr-pipeline-plan.md):
- Protocol/ABI: ColorInfo on the Welcome + a 0xCE HdrMeta datagram carry the source colour
space + HDR10 static mastering metadata (quic.rs, abi.rs connect_ex5 fixing caps=0).
- New platform-independent, unit-tested HDR static-metadata helpers (hdr.rs): chromaticities
(1/50000), mastering luminance (0.0001 cd/m2), MaxCLL/MaxFALL in HDR10/ST.2086 units.
- Capture/encode hooks (capture.rs, encode.rs set_hdr_meta) + Linux client / probe plumbing.
Security-audit hardening — top 3 from docs/security-review.md, each adversarially verified:
- #1 [HIGH] Secret file permissions. The host key.pem/cert.pem and both trust stores are now
written owner-only: 0600 + dir 0700 on Unix (mirrors mgmt_token), best-effort
SYSTEM/Administrators/OWNER-only icacls DACL on Windows (%ProgramData% is Users-readable).
Closes a local key-disclosure -> host-impersonation gap. New gamestream::{create_private_dir,
write_secret_file} + a 0600 regression test.
- #2 [HIGH] Native SPAKE2 PIN is single-use. The PIN is consumed the moment the host sends its
key-confirmation (which lets the client test its one guess), before reading the proof, so any
completed attempt -- right OR wrong -- disarms the window. A wrong PIN isn't observable
host-side (the client aborts before sending its proof), so consuming on first attempt is what
delivers the documented "one online guess" instead of an unbounded brute-force of the static
4-digit PIN. Test verifies single-use.
- #3 [MEDIUM] RTSP packetSize is bounded ([64,2048] in stream_config) and VideoPacketizer::new
uses saturating .max(1), killing a PRE-AUTH div-by-zero/underflow panic of the video thread.
Tests for {0,15,16,17} + out-of-range rejection.
fmt + clippy -D warnings clean; full workspace test suite green (93 host tests).

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).

The management console is a Nitro `node-server` build (per web/vite.config.ts) — it must be
run with `node`, not `bun`. Run under bun it 500s on every page render with
"Cannot find package 'srvx'": bun mis-resolves Nitro's externalized server deps from the
nested SSR chunk at request time. (This was pre-existing — the old manual pfweb.sh ran it
with bun too.)
- Provision `nodejs` in the pf2 distrobox; run the web service with `node .output/server/index.mjs`.
- Use `enable` + `restart` (not `enable --now`) so re-running the installer actually applies
unit-file changes instead of no-opping against the running service.
Verified on the Deck: web `/login` now returns 200 (was 500), "Listening on http://0.0.0.0:3000",
no srvx error.

SteamOS is immutable read-only Arch, and the Deck is AMD (VAAPI) — so none of the
checked-in packaging (arch/sysext is NVENC-first + client-oriented, deb/rpm are
soname-mismatched) actually installs a working host on a Steam Deck. The proven path
(distrobox-built native binary + systemd-run units) was 100% manual. Make it one command.
- scripts/steamdeck/install.sh — idempotent installer: ensure the pf2 Debian-trixie
distrobox + toolchain → build host (+web console) → write config (generated web login
password) → raise UDP buffers to 32 MB + udev + input group (sudo, skipped gracefully
if unavailable) → install + start punktfunk-host / punktfunk-web systemd USER services
with linger. Flags: --open (accept unpaired clients), --no-web, --src=DIR. Builds
on-device so a rebuild always matches the running SteamOS (no prebuilt-binary fragility
across OS updates); VAAPI on the Deck's AMD GPU.
- scripts/steamdeck/update.sh — rebuild from current source + restart (config/pairings persist).
- scripts/steamdeck/README.md — deep reference (why on-device, what's installed, gotchas).
- docs-site: new "Steam Deck (Host)" guide + sidebar entry; install.md splits Arch from the
Steam Deck host path; packaging/arch/README points Deck-host users here and corrects the
stale "NVENC-only" note (VAAPI host encode landed).
Live-validated on the Deck: installer runs clean, both services come up, host listens
(QUIC :9777 + mgmt :47990), web serves (302→login); on a client connect it takes over the
Game-Mode gamescope session at the client's mode, captures via PipeWire, and VAAPI-encodes
(hevc_vaapi) — full pipeline confirmed in the host journal.

On a clean link the flat 20% FEC is pure waste: extra wire bytes AND extra
packets. On a packet-rate-bound uplink (the Steam Deck's WiFi tx caps ~22k pps
regardless of bitrate) those extra packets directly cost goodput — measured at
200 Mbps goodput, 20% FEC drove ~10% loss vs ~2.6% at 0% (it saturated the link).
Adaptive FEC closes the loop:
- Client measures the loss FEC is absorbing each ~750 ms window from session stats
(recovered shards / received, + a bump when a frame went unrecoverable) and sends
a periodic `LossReport { loss_ppm }` on the control stream (new message;
`window_loss_ppm` helper, shared + unit-tested). Connector (Apple/Linux/Windows)
and probe both report; suppressed during a speed test so its filler can't skew it.
- Host maps loss → recovery % (`adapt_fec`: ≈ loss×1.4 + 1pt, clamped 1..50) and
applies it live via `Session::set_fec_percent` (the wire is self-describing — each
packet carries its block's data/recovery counts, so the receiver needs no notice).
A clean link decays to ~1%; loss ramps it up and converges.
- `PUNKTFUNK_FEC_PCT`, when set, now PINS FEC static (disables adaptation) so
speed-test / measurement runs keep a fixed, known overhead. Unset ⇒ adaptive,
starting at 10%.
An older host ignores LossReport (unknown control message) and keeps static FEC;
an older client simply never reports and the host holds its start value. Builds +
clippy + fmt + tests green (adapt_fec / window_loss_ppm / loss_report unit tests).

HDR (10-bit BT.2020 PQ) works end-to-end with the Windows host — it captures
an HDR desktop (WGC FP16 / Desktop-Duplication FP16 for the secure desktop)
and encodes HEVC Main10 to HDR-capable clients (Windows, Android). Only the
Linux host is blocked upstream (no 10-bit compositor capture). Corrected the
roadmap (grid + shipped/blocked), Windows Host page, status, and CLAUDE.md.

- install (host): add a Windows (NVIDIA) section with signed-installer and
certificate-trust steps; note the .cer is the same across releases.
- install-client: clarify the Windows MSIX certificate is the same every
release (trust once, updates need nothing).
- Move "Project & Internals" out of the public docs site: relocate
implementation-plan, apple-stage2-presenter, gamescope-multiuser,
dualsense-haptics, ci, and gamestream-host-plan to docs/; drop them from
the nav. Move windows-host into Host Setup.
- Rewrite roadmap as a lean public page with an at-a-glance grid and
current statuses (Windows host shipped/beta, Apple incl. tvOS shipped,
Android shipped, concurrent sessions + delegated pairing done).
- Fix status.md link to the now-internal implementation plan.

The punktfunk/1 speed test was unusable across every client/host: at the start of
a burst a little data got through, then everything read as dropped (~10 MB total).
Two compounding bugs:
1. Receive side measured throughput from fully-reassembled FLAG_PROBE *access
units* only. The instant loss crossed the 20% FEC budget no AU completed, so the
figure cliffed to 0 / 100% loss even though most bytes still arrived — a binary
cliff, not a graded measurement.
2. Send side blasted each filler AU (up to 256 KB ≈ 200 packets) into the socket
buffer in one unpaced batch, unlike the real video path which paces. On a small
buffer (e.g. the Steam Deck's 416 KB) a single AU overflowed it, so the test
measured self-inflicted buffer overflow instead of the link.
Fixes:
- Host `run_probe_burst` keeps each AU a small (~16 KB) burst and paces by the byte
budget, mirroring `paced_submit`; reports the WIRE packets the kernel accepted and
the ones the send buffer dropped (stat deltas), separating host-side drops from
link loss.
- `ProbeResult` gains `wire_packets_sent` + `send_dropped` (back-compat decode: a
21-byte pre-wire-stats result still decodes, new fields 0).
- Clients (probe + connector) count delivered traffic at the packet level via
`session.stats()` deltas over the burst window, so throughput/loss degrade
gracefully. Connector freezes the delivered figure when the host report lands so
resumed video can't inflate it. New `ProbeOutcome`/`PunktfunkProbeResult` fields:
`host_drop_pct`, `wire_packets_sent`, `send_dropped`.
Validated on loopback (graded 142→1391 Mbps, host_drop/link_loss split correctly,
no cliff) and live against the Deck: clean to ~200 Mbps goodput / 273 Mbps wire at
0% link loss, host send buffer the wall above that (the lever-#1 target).

- Add the Windows host (implemented & shipping: DXGI capture, SudoVDA
virtual display, NVENC, ViGEm, WASAPI, LocalSystem service installer;
NVIDIA-only, x64-only) — it was absent entirely.
- Add the Android client (full client: AMediaCodec/HDR10 decode, Oboe
audio + mic, gamepad feedback, discovery, pairing, Compose phone+TV UI;
Google Play internal testing) and drop the stale "scaffolds" item.
- macOS stage-2 presenter: built + live-validated behind the opt-in flag,
not "next".
- Concurrent sessions + delegated pairing approval marked done.
- Layout/CI: note Windows host backends and per-client release workflows.

Refresh the README and documentation for public visitors:
- README: public-facing rewrite with accurate status for all four native
clients (macOS, Linux, Windows, Android) and the Windows host.
- docs site: fix stale client status (Android is a full client, not a
scaffold; Windows client is stage-1 complete + signed MSIX), add the
missing Android client section, correct "which client" guidance.
- Windows host: corrected from "deferred/scoped" to implemented & shipping
(NVIDIA-only, x64-only) across windows-host, roadmap, status,
requirements, running-as-a-service, and the README.
- Remove internal infrastructure from public docs (box names, private IPs,
SSH/token commands, deploy topology); rewrite status.md as a public
project-status page; sanitize ci.md and implementation-plan.md.
- Update clients/android and clients/apple READMEs to current state.

The Steam Deck (SteamOS) ships its OWN gaming session — `gamescope-session.target`
driven by `/usr/lib/steamos/gamescope-session`, not Bazzite's `gamescope-session-plus`.
That script `exec gamescope`s with HARDCODED physical-panel args (`-w 1280 -h 800 -O
'*',eDP-1`) and launches Steam via a SEPARATE `steam-launcher.service`, so the existing
managed-session path (which assumes session-plus) couldn't honor the client's mode — an
attach captured the panel's native 1280x800 instead.
Add a SteamOS branch to the managed-session path: detect it, write a `gamescope` PATH-shim
that rewrites the hardcoded args to `--backend headless -W <client> -H <client> -r <hz>`,
drop a transient user `gamescope-session.service.d` override pointing PATH at the shim +
the mode, then RESTART the whole target so `steam-launcher.service` brings Steam up IN the
headless gamescope at the client's resolution. Attach to the one fresh node (the restart
kills any prior gamescope, so no stale-node attach). Restore-on-disconnect removes the
override + restarts the target back to the physical panel (debounced; skipped if the user
switched to a desktop session). All user-level (`systemctl --user`) — no root.
Also widen `build_pipeline_with_retry` to 8 attempts (~90s): a host-managed gamescope
session cold-starting Steam Big Picture takes 30-60s to first frame, and a first-connect
timeout would tear down the warm session (forcing another cold start on reconnect).
Permanent failures still fail fast via `is_permanent_build_error`.
Validated live on a Steam Deck: Game Mode auto-detected, host takes over headless at the
client's mode (720p / 1080p), Steam Big Picture streamed glass-to-glass to the Mac at the
requested resolution. Single-tenant (concurrent clients at different modes still thrash —
a follow-up).

WiFi drivers (e.g. ath11k on the Steam Deck) return ENOBUFS — not
EAGAIN/EWOULDBLOCK — when the tx queue is momentarily full. Rust maps
ENOBUFS to ErrorKind::Uncategorized, so `is_transient_io` (which only
matched WouldBlock/ConnRefused/ConnReset) treated it as a real error and
tore the whole stream down on a single transient burst.
This presented as a vicious Heisenbug on the Deck: the native host
streamed flawlessly on loopback and under a debugger (anything slow
enough not to fill the small ~416 KB wlan0 buffer), but died at full rate
cross-machine over WiFi — flaky hang-or-SIGKILL because tx-queue-full is
probabilistic. Diagnosed live via a forced core dump (gdb on the hung
core): the data-plane thread had bailed on a fatal send error.
Treat ENOBUFS (and asynchronous network-path blips ENETUNREACH /
EHOSTUNREACH / ENETDOWN / EHOSTDOWN) as a lossy drop like WouldBlock —
FEC + the next frame recover. Validated: 6/6 back-to-back cross-machine
streams over the Deck's WiFi, host stable, p50 ~4.4 ms (one run dropped
4/300 frames *gracefully*, 0 mismatched — the fix working as intended).
Also surface a data-plane bind/hole-punch failure directly in punktfunk1
(it was previously only reported after teardown, which a stall could
swallow entirely).

Pull the same footer from the shared unom CMS global (cms.unom.io) and render
it globally under both the home and docs layouts. Read-only typed fetch in a
server-side root loader (falls back to null on a CMS hiccup). Root-relative
links target the marketing site, so they're resolved against its origin (the
docs don't host /legal/* etc.); themed with Fumadocs tokens for light/dark.

Replace the CSS-mask/webp wordmark with the inline vector from

Swap the plain "punktfunk" text in the nav and landing hero for the real
brand wordmark from the marketing site. The source asset is a single
light-violet variant (made for dark surfaces), so it's painted as a CSS

to stay legible with the docs' light/dark toggle.

Theme the Fumadocs docs site with the punktfunk identity, mirroring the
marketing site:
- Swap the stock `neutral` preset for `purple`, then override --color-fd-*
with the violet lens-mark palette (#6c5bf3 / #a79ff8). The brand is the
violet, not the site's blue marketing background, so the blue is not used
as a reading surface; dark mode tints the chrome toward the app-icon
violet-dark (#1c1530).
- Adopt @unom/ui's token contract (--brand/--primary/--accent + bg-brand
etc.) as the shared token source, and @source its dist.
- Load Geist (the brand typeface) via @fontsource-variable/geist.
- Add the BrandMark lens to the nav + landing hero, wire the brand
favicon.svg, and add Docs/Website nav links.
- Keep the Fumadocs light/dark toggle.

The Phase 3 GPU-aware codec mask (e2cef91) probes VAAPI on any non-NVIDIA host.
On a GPU-less box (CI container: no /dev/nvidia* -> `auto` picks VAAPI, but there's
no VA display) the probe returns all-false, so the mask was 0 -- the host
advertised NO codecs, and the serverinfo unit test failed.
Fall back to the static superset when the probe yields nothing (VAAPI wasn't
usable, not "the GPU encodes nothing"); quiet ffmpeg's expected "No VA display"
error during the probe; and assert the test against codec_mode_support() rather
than a hardcoded 65793 so it's deterministic regardless of the build host's GPU.

Polish for AMD/Intel support:
- GameStream serverinfo advertises only codecs the GPU can ACTUALLY encode on
the VAAPI backend (probed once by opening a tiny encoder per codec). AV1
encode is narrow (Intel Arc/Xe2+, AMD RDNA3+/RDNA4) and an old iGPU may lack
HEVC, so a Moonlight client never negotiates a codec the encoder can't open.
NVENC/Windows keep the Moonlight-validated static mask. Validated on a Radeon
780M: h264/h265/av1 all probe true -> mask unchanged (65793).
- Packaging: Recommends mesa-va-drivers + intel-media-va-driver (deb) /
mesa-va-drivers + intel-media-driver (rpm) so the auto-selected VAAPI backend
works out of the box on AMD/Intel; NVIDIA boxes can --no-install-recommends.
(Fedora note: stock mesa-va-drivers disables HEVC/AV1 -- needs the freeworld
variant from RPM Fusion.)
- De-NVIDIA-fy the user-facing encoder log/context strings ("open NVENC" ->
"open video encoder") now that VAAPI is a first-class backend.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Phase 2 of AMD/Intel support: the VAAPI encoder now takes the capture dmabuf
directly and does the RGB->NV12 colour conversion on the GPU's video engine,
eliminating the host-side de-pad + swscale CSC + upload the CPU path pays.
- capture: a vendor-neutral FramePayload::Dmabuf (dup'd fd + fourcc/modifier/
layout). When zero-copy is on, the EGL->CUDA importer is unavailable (any
non-NVIDIA host), and the backend is VAAPI, the capturer advertises LINEAR
dmabuf and hands the raw buffer to the encoder instead of CPU-copying it.
- encode/vaapi: the encoder self-configures from the first frame's payload (no
open_video signature change). The dmabuf arm wraps the buffer as an
AV_PIX_FMT_DRM_PRIME frame and pushes it through a filter graph
buffer(drm_prime) -> hwmap(vaapi) -> scale_vaapi=nv12 -> buffersink; the
encoder takes NV12 surfaces straight from the sink. The Phase 1 CPU-upload
path is kept as the other arm (used when capture produces CPU frames).
Live-validated on a Radeon 780M (real Sway/xdpw desktop capture): correct,
pixel-perfect HEVC, and ~10x less host CPU at 1440p (4.2s -> 0.4s of CPU for
300 frames) -- the de-pad/CSC/upload moves to the GPU. NVIDIA unchanged
(zero-copy still imports to CUDA; the passthrough path only engages on
non-NVIDIA hosts).

The CPU de-pad path trusted PipeWire's MAP_BUFFERS slice (`d.data()`, length =
`data.maxsize`). xdg-desktop-portal-wlr hands MemFd ScreenCast buffers whose
maxsize exceeds the bytes PipeWire actually maps into our process, so reading to
maxsize ran off the end of the mapping and SIGSEGV'd the capture thread —
crashing every CPU-path capture on Sway/wlroots (and thus any non-NVIDIA host,
which has no CUDA zero-copy importer and always falls back to this path).
mmap the fd ourselves, sized to its real length (fstat), for any fd-backed
buffer (MemFd SHM or DmaBuf); fall back to `d.data()` then drop. The existing
`needed > avail` guard now drops cleanly instead of over-reading. This also
subsumes the original "MAP_BUFFERS didn't map a Vulkan dmabuf" fallback.
Verified: fixes real Sway-desktop portal capture -> VAAPI HEVC on a Radeon 780M
(correct image + colours); the NVIDIA zero-copy path (returns before this code)
and the NVIDIA/KWin CPU path (self-mmap, fd_len == maxsize) both still work.

The host hard-linked libcuda.so.1 on Linux (`#[link(name="cuda")]` in
`zerocopy::cuda`), so the binary wouldn't even *start* on a non-NVIDIA box —
the dynamic loader can't resolve the NEEDED libcuda. That blocked running the
new VAAPI (AMD/Intel) path on a machine without the NVIDIA driver.
Resolve the 18 CUDA Driver API symbols at runtime via `libloading` instead.
Same-named wrapper fns forward to the dlopen'd table (call sites unchanged);
when libcuda is absent they return a non-zero CUresult so `context()` fails
cleanly and the capturer falls back to the CPU path. The library handle is
leaked (process-lifetime, like the shared context).
One Linux binary now runs on NVIDIA (CUDA zero-copy -> NVENC) and on AMD/Intel
(VAAPI, no NVIDIA driver). Verified: the NVIDIA dev box still does dmabuf->CUDA
zero-copy; on a Radeon 780M box the host builds with no libcuda present, the
binary has no NEEDED libcuda entry, and VAAPI encode runs with no stub.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The Linux host was NVENC/CUDA-only. Add a VAAPI encoder — one libavcodec
backend (h264/hevc/av1_vaapi) covering both AMD (Mesa radeonsi) and Intel
(iHD) — behind the existing `Encoder` trait, and turn `open_video`'s Linux
arm into a vendor dispatcher: `PUNKTFUNK_ENCODER=auto|nvenc|vaapi` (default
auto: NVENC when a CUDA frame or /dev/nvidia* is present, else VAAPI). The
NVIDIA path is unchanged — auto resolves to NVENC on an NVIDIA box and the
bitrate-probe loop moved verbatim into `open_nvenc_probed`.
`VaapiEncoder` mirrors the NVENC hwframes pattern with AV_HWDEVICE_TYPE_VAAPI.
The CPU-input path swscales packed RGB -> NV12 (BT.709 limited, VUI signalled)
and uploads into a pooled VA surface (av_hwframe_transfer_data), preserving the
low-latency model (infinite GOP, on-demand forced IDR, async_depth=1, CBR when
the driver supports it). It works on a non-NVIDIA box with no capture changes:
the capturer already falls back to CPU frames when its EGL->CUDA importer can't
initialise (no libcuda).
Live-validated on a Radeon 780M (RDNA3): hevc/h264/av1_vaapi all encode,
HEVC/H264 decode cleanly with correct BT.709-limited colours, infinite GOP
preserved. Zero-copy dmabuf import (the high-res perf lever) is next.

The host is NVIDIA/NVENC + SudoVDA coupled; Windows ARM64 has neither an NVIDIA
driver nor an ARM64 SudoVDA, so an ARM64 host would install but couldn't encode
or make a virtual display. Document the deliberate x64-only scope so it doesn't
get re-litigated. ARM64 stays client-only.

Root cause of the persistent ISCC "path not found": ISCC.exe is 32-bit, and the
self-hosted runner runs as SYSTEM, so the checkout lives under
C:\Windows\System32\config\systemprofile\.cache\... . WOW64 file-system
redirection rewrites a 32-bit process's System32 reads to SysWOW64 (where nothing
exists), so ISCC died opening the .iss before it even printed its version line.
(The smoke-test diagnostic compiled fine precisely because it lived at C:\t\out.)
Fix: copy every file ISCC reads (the .iss + host.env.example + README.md) into
the non-redirected build dir C:\t\out and compile from there; BinDir, StageDir,
and OutputDir already live under C:\t. Removed the now-spent smoke diagnostic.
