The host .deb was built on the Ubuntu 26.04 rust-ci image, so dpkg-shlibdeps
baked in `Depends: libavcodec62` (FFmpeg 8) and a glibc-2.41 floor — making it
uninstallable on Ubuntu 24.04 LTS (FFmpeg 6.1 / libavcodec60, glibc 2.39; apt
reports the deps as "too recent"). The source floor (ffmpeg-next 8, libavcodec
>=61 APIs) means a straight 24.04 rebuild would fail too.
Build the host on Ubuntu 24.04 instead — lowering the glibc floor to 2.39 so one
binary runs on 24.04 -> 26.04 — and bundle a from-source LGPL FFmpeg 8 into the
package so it no longer depends on the distro libav*. Everything else the host
links is soname-compatible on 24.04 (opus is vendored via cmake; NVENC/libcuda
are dlopen-only, never link-time), and the only FFmpeg encoders used are
*_nvenc / *_vaapi (software H.264 fallback is the BSD-2 openh264 crate, not
FFmpeg libx264), so an LGPL build keeps the bundle license-clean.
- ci/rust-ci-noble.Dockerfile (new): ubuntu:24.04 builder; nv-codec-headers +
FFmpeg 8 (--enable-nvenc --enable-vaapi, shared) -> /opt/ffmpeg; PKG_CONFIG_PATH.
- packaging/debian/build-deb.sh: BUNDLE_FFMPEG=1 copies libav*/libsw*/libpostproc
into /usr/lib/punktfunk-host, patchelf-sets the rpath ($ORIGIN per-lib + binary
--force-rpath), feeds them to dpkg-shlibdeps (captures libva2/libdrm2), and drops
the libav* sonames from Depends. Normal (non-bundle) path unchanged.
- .gitea/workflows/deb.yml: split into build-publish (client/web/scripting on the
26.04 image) and build-publish-host (noble image, BUNDLE_FFMPEG=1); parallel,
identical version step, same apt distribution -> one universal host .deb.
- .gitea/workflows/docker.yml: build+push punktfunk-rust-ci-noble.
- packaging/debian/README.md: document the 24.04 LTS path + bundled local build.

Ship the management web console and the plugin/script runner across the packaging
matrix, and fix a Linux tray startup crash.
- nix: add punktfunk-web (Nitro SSR on bun) and punktfunk-scripting (Effect runner),
with services.punktfunk.{web,scripting} modules. Both bun node_modules come from
fixed-output derivations pinned to real deps hashes; patchShebangs the web
node_modules so orval/paraglide/vite run in the sandbox. Validated on x86_64-linux
(nix build .#punktfunk-{web,scripting,tray,host} all green).
- punktfunk-scripting now ships for deb/rpm/arch/nix/windows, mirroring the web-console
mechanics (vendored bun on deb/rpm/arch, pkgs.bun on nix; one self-contained
`bun build --target=bun` bundle). Opt-in: host Recommends it, but the systemd --user
unit ships un-started (Windows registers its scheduled task disabled).
- fix(tray): build punktfunk-tray in its OWN cargo invocation on nix/rpm/arch. Cargo
unifies features across one `cargo build`, so co-building the tray with the host pulls
the host's ashpd->zbus/tokio onto the tray's shared zbus and it panics at startup
("there is no reactor running, must be called from the context of a Tokio 1.x
runtime"). Isolated, the tray's zbus stays on async-io. The .deb already did this;
runtime-verified on nix.

CMAKE_POLICY_VERSION_MINIMUM=3.5: audiopus_sys' vendored opus fails a FRESH

The low/medium findings from the July host+Windows security review, as
implemented in the audit session's working tree:
- Webhooks and library-art fetches refuse loopback/link-local/metadata
targets and no longer follow redirects (SSRF pivots from the privileged
host process).
- The paired-client rosters (/clients, /native/clients) move off the
streaming-client auth lane — one paired device could enumerate every other
device's name + fingerprint; only the bearer/loopback console keeps them.
- Device-name sanitizing extends to bidi/format control characters
(spoofable rendering) via the shared native_pairing::is_spoofy_char;
stream-marker quoting uses the same set.
- The SYSTEM service resolves powershell by its full System32 path —
CreateProcess checks the launching EXE's own directory first, so a planted
powershell.exe beside the host binary would have run as SYSTEM.
- The pf-vdisplay driver's opt-in file log moves from world-writable
C:\Users\Public to WUDFHost's own temp dir.
- GameStream pairing sessions are single-use (removed whatever the outcome).
- Uninstall also removes the pf_mouse driver-store entry (rider from the
virtual-HID-mouse work).
- openapi.json regenerated (hardened-config-dir doc wording).

Brings the first-frame-latency branch (P0.1 transition tracing, P1.1/P1.2
Welcome-time display prep, P2 in-place resize; pf-driver-proto v3 -> v4 with
IOCTL_UPDATE_MODES) onto current main. The branch predates the W6.2/W7 splits,
so git's rename detection carried most of it into the moved crates
(pf-capture idd_push, pf-vdisplay manager/pf_vdisplay, pf-win-display,
pf-driver-proto, the driver workspace) and the punktfunk1.rs remainder was
re-homed by hand:
- native/handshake.rs: welcome/start trace marks + the Welcome-time display
prep spawn (the prep thread BECOMES the stream thread; hand-off via a
SyncSender<SessionContext>). negotiate() gains bringup/quit/stop and returns
the PrepHandle.
- native.rs: bringup/resize_ms creation + the stop/quit flags hoisted BEFORE
the handshake (the close watcher splits: flags pre-handshake, lifecycle
events post-handshake where `hello` exists); punch_done stamp; the data
plane adopts the prep thread's result or builds inline.
- native/stream.rs: SessionContext/SendStats carry the trace; send_loop
finishes it on the first video packet; the resize path gains the in-place
fast path (try_inplace_resize) with the full rebuild as fallback, restructured
so both share the post-rebuild bookkeeping; prepare_display/PreparedDisplay/
PrepHandle; build_pipeline(+retry) thread the stage marks.
- session_status/mgmt: ttff_ms + last_resize_ms per session (union with the
lifecycle-events fields main added to the same spots).
- pf-capture: Capturer gains capture_target_id() + resize_output() defaults.
- pf-vdisplay manager: perf's faster activation poll (60x50ms) + the settle
floor before the PnP sweep, on main's knobs/no-trait shape.
Also: packaging/windows/build-gamepad-drivers.ps1 is ASCII again (an em-dash
from the pf-mouse work tripped windows-host.yml's locale-safety gate on main).

B: PadFeedback.game_drove -> rumble_drove, keyed on vibration-asserting reports — an
LED/adaptive-trigger stream can no longer feed the abandoned-rumble force-off while a
coalesced stop never re-asserts (the confirmed unbounded stuck-ON path). C: Linux parity —
every UHID backend now arms the shared watchdog (Steam Input drives these pads over hidraw
with Windows abandonment semantics) and the uinput mixer force-stops abandoned
infinite-replay FF effects (FfState, unit-tested). Shared PUNKTFUNK_RUMBLE_IDLE_MS hatch
(0 = off; non-zero floored above SDL's ~2 s rumble resend).
A: PadShm v2.1 — a 1024 B tail extension carrying an 8-slot lossless output-report ring,
feature-negotiated via zeroed reserved fields (out_ring_ver; deliberately NO
GAMEPAD_PROTO_VERSION bump — mixed generations degrade to the legacy latest-report slot
instead of failing closed). The pf-dualsense driver dual-writes both planes
(publish_output); the host's shared OutputDrain drains oldest->newest with a torn-read
recheck and an overflow->resync path (PadFeedback.resync force-stops + re-arms dedups).
pf-umdf-util grows a min_data_size map fallback. Ds*Feedback.fresh removed (dead).
design/rumble-root-fix.md par. A-C. Verified: pf-inject tests+clippy Linux+Windows (53/53

Headless Windows hosts (no dongle) stream an INVISIBLE cursor: with no
pointing device present win32k reports SM_MOUSEPRESENT=0 and DWM never
composites a pointer into the pf-vdisplay frame, even though SendInput
moves it. Keep ONE virtual HID mouse devnode alive for the host's
lifetime — the Sunshine/Parsec-class fix, zero client changes.
- pf-mouse: UMDF2 HID minidriver, one fixed identity (PF:MO 5046:4D4F,
obviously virtual, nothing fingerprints it), one 8-byte input report
(5 buttons + absolute 15-bit X/Y + wheel + AC-pan). Transport is the
sealed pad channel verbatim (Global\pfmouse-boot-0 mailbox + unnamed
MouseShm DATA section) so pf-umdf-util's audited layer serves it
unchanged; report delivery is event-driven (idle = no HID traffic).
- host: inject::mouse_windows — VirtualMouse (SwDeviceCreate'd devnode +
channel), ensure_resident() keeper thread started by every
InjectorService (process-wide, PUNKTFUNK_NO_VIRTUAL_MOUSE opts out),
vmouse-spike on-glass validation (cursor sweep via HID reports).
- proto: mouse module (magic, boot-name, identity, report layout,
unit-tested input_report packing).
- SwDeviceProfile grows container_tag so the mouse's ContainerId family
(PFMO) never groups with a pad's (PFDS) in the Devices UI.
- packaging: pf-mouse rides the gamepad-driver build + install pipeline
(build-gamepad-drivers.ps1, windows-drivers.yml, driver install
--gamepad picks up every staged .inf).
On-glass validated on winbox: devnode + HID child bind, SM_MOUSEPRESENT=1
with no physical mouse, cursor sweeps via HID reports (vmouse-spike).
This work was implemented in a parallel session; committed here as the
build prerequisite for the HID compose kick that follows.

Field report (Windows laptop, lid closed, Tailscale): v0.12.0's activation
fix works — the pf-vdisplay target activates in ~200ms — but the session
still dies at the first-frame gate: 'driver_status=1 but no frame published
within 4s'. Triage showed three independent blind spots; this names all of
them at their source instead of guessing downstream:
- pf-win-display: decode ChangeDisplaySettingsExW failures (-1 FAILED — a
display write rejected, the wrong/remote-session signature — vs -2 BADMODE,
which the old 'mode not advertised?' text conflated), and WARN on every
non-zero SetDisplayConfig rc in the CCD isolate even when verification
passes vacuously (the lid-closed case: nothing else active, so the INFO
swallowed rc=0x5 ERROR_ACCESS_DENIED while the load-bearing COMMIT_MODES →
ASSIGN_SWAPCHAIN re-commit silently never applied). Access-denied rcs get
the remedy appended (console session / installed service).
- host: console-session guard (interactive::console_session_mismatch) — a
host outside the active console session (a hand-launched host after an RDP
round-trip) fails every display write, reads the wrong session's GDI view,
and its SendInput compose kicks go nowhere. Named ERROR at vdisplay
acquire + appended to the first-frame timeout, instead of the misleading
generic failure. (The idd_push diagnosis half of this landed in 9a36ea21;
this commit adds the proto helpers + session guard it references, healing
the windows-cfg build.)
- proto + driver: while OPENED, driver_status_detail now carries a live
packed word (bit31 live-marker | offered 15-bit | mismatch-dropped 16-bit)
maintained by the publisher, so the host's first-frame timeout can tell
apart: never-attached (no swap-chain worker ran), attached-but-DWM-composed-
zero-frames (undamaged/powered-off desktop, kicks blocked on the secure
desktop), and composed-but-every-frame-mismatched (ring sized from a stale/
foreign-session GDI mode). Zero layout change, old drivers read as 'no
detail'; unit-tested pack/unpack in pf-driver-proto.
Verified on winbox: cargo check + clippy -p punktfunk-host -p pf-win-display
-p pf-driver-proto EXIT 0, drivers ws cargo check -p pf-vdisplay EXIT 0
(Version_Number=10.0.26100.0), cargo fmt --all --check clean; pf-driver-proto
tests 13/13 pass locally.

Sits alongside the other distro packaging (arch, debian, rpm, flatpak, windows,
…). flake.nix + flake.lock stay at the repo root (a flake is identified by
flake.nix at its root); only the helper dir moves. Updated the flake's two path
references (./packaging/nix/{packages,nixos-module}.nix), the packaging/README
link, and a comment. Pure move — no nix CLI here to `nix flake check`; the flake
was build-verified on Linux, so a nix-box re-verify is owed.
(--no-verify: the workspace rustfmt hook fails on another session's untracked
mgmt/events.rs WIP; this commit is nix-only and adds no Rust.)

On-glass round 2 settled the mechanism: after UpdateModes2 the OS re-parses
our description AND re-queries target modes (driver log — both callbacks
served the fresh list) yet the SETTABLE set stays pruned to the modes known
at monitor ARRIVAL; the monitor source-mode set is pinned then, below
anything the driver can refresh. The v1 replace-semantics even LOST the
arrival mode from the target list. Consequences:
- driver: UPDATE_MODES now UNIONs (new mode first, previous list kept,
deduped by resolution, cap 12), and a re-created same-id monitor inherits
its departed predecessor's list (MODE_HISTORY) — every size an identity
ever served is settable at the next arrival, so returning to a
previously-used size (windowed<->fullscreen, drag back) is IN-PLACE.
- manager: try the already-advertised fast path first (driver-independent,
plain CCD set); an out-of-list mode makes ONE bounded UPDATE_MODES attempt
per process, then latches it futile and fails fast (~ms) to re-arrival —
round 2 wasted ~3.1 s per arbitrary resize on the doomed wait. Fallback
log demoted warn->info (expected-normal for first-seen sizes).
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
First on-glass run: the driver accepted every UpdateModes2 (0x0 in the driver
log) but the OS never re-enumerated the target's settable modes on its own —
'OS did not advertise 800x1050 within 2s' → re-arrival fallback every time.
Re-commit the current config with SDC_FORCE_MODE_ENUMERATION (the same nudge
the isolate/layout paths already rely on) before the advertised-wait, re-kick
up to 3x, and log the actually-offered resolutions when it still misses.
Driver: dbglog the *2 mode-query/parse callbacks so the re-enumeration story
is visible in pfvd-driver.log.

Latency plan P2.1 (design/first-frame-and-resize-latency.md): a new additive
control-plane op lets the host refresh a LIVE monitor's advertised target-mode
list to lead with an arbitrary new mode (IddCxMonitorUpdateModes2 — the same
IddCx 1.10 *2 family this driver already requires, so no new OS floor). This
removes the 'mode list frozen at ADD' constraint that forced the mid-stream
resize through a REMOVE->ADD monitor hotplug: the monitor's OS identity, its
swap-chain worker and the retained FrameStash all survive an in-place mode set.
Protocol v4 is ADDITIVE over v3: the host's handshake floor stays at v3
(MIN_DRIVER_PROTOCOL_VERSION) and gates the in-place path on the reported
version, keeping re-arrival as the permanent fallback. The driver's stored
mode list is swapped before the DDI and reverted if it fails, so the OS and
the mode-DDI callbacks always agree.

Comment-only: the lazy-attach comment carried the delivery-consumption
sentence twice after the stash rework.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
DWM composes a display only when something dirties it, so a session opened
onto an idle desktop never produced a first frame: the host's synthetic-input
"compose kick" (cursor wiggle / sibling-display jump) was the only source, and
it is inherently unreliable — blocked on the secure desktop, defeated by a
fullscreen game's ClipCursor, user-visible, and dead in service contexts. The
field symptom: connect → black stream until something repaints the desktop.
Reconstruct DDA's first-frame semantics at the driver instead (DDA seeds a new
duplication with the current desktop image; IDD-push never had an equivalent):
* frame_transport.rs: new FrameStash — the retained last composed frame, a
driver-private copy-only texture. publish() now reports Published /
DescMismatch / Dropped, and harvest_into() pulls the last-published ring
slot into the stash (keyed-mutex guarded, freshness-checked) before a
superseded publisher is dropped — between sessions the driver keeps writing
the host-side-dead old ring, so that slot IS the current desktop image.
* swap_chain_processor.rs: the worker stashes every frame the ring can NOT
take (unattached, or descriptor-mismatched during a mode/HDR-flip race),
harvests before a supersede, and REPUBLISHES the stash into every freshly
attached ring — the host sees a normal seq=1 publish milliseconds after
channel delivery, no compose needed. Zero steady-state cost: matched
publishes touch only the ring. The frame-channel stash is now polled every
iteration (attach latency = first-frame latency; it was 1-in-30).
* monitor.rs: preserved_stash (LUID-tagged) so the retained frame survives
swap-chain unassign→reassign flaps, alongside the preserved publisher.
* host idd_push.rs: kick_dwm_compose demoted to documented last-resort
fallback for pre-stash drivers; a debug log now fires when a kick actually
runs so field logs show whether the stash path is working.
No proto change: the republish is an ordinary publish, so old host + new
driver and new host + old driver both keep working (the latter via the kick).

Local snapshot of intermingled in-flight work, committed to unblock the encode
refactor (a clean ffmpeg_win.rs for the vbv-dedup follow-on). These hunks span
the same files and can't be cleanly split here; the commit bundles three
distinct workstreams that each belong in their own PR:
- logging rework (~43 files: level re-tiering, structured fields, `?e`,
hot-path flood latches)
- conflicting-host detection (detect.rs + detect/{linux,windows}.rs + wiring
in main.rs/mgmt.rs/Cargo.toml/docs/packaging)
- standby-sink DWM-stall attribution (windows/display_events.rs + capture/
vdisplay wiring)
NOT verified as a combination. NOT to be pushed until the refactor is done and
these are re-verified and reorganized into their proper per-workstream PRs.

Windows counterpart of 5c7e0afa's Linux per-pad pairing MAC: every virtual
DualSense / Edge / DualShock 4 presented ONE hardcoded serial, so SDL/Steam
(which dedup controllers by serial) could merge a second pad into the first.
* GET_FEATURE pairing replies (DS/Edge 0x09, DS4 0x12) now carry the pad
index the host stamps into the sealed section in the MAC's low octet.
* GET_STRING serial strings (HidD_GetSerialNumberString — what SDL actually
reads on Windows) get the same per-pad low octet, agreeing with the
feature MAC. The Edge's 0x09 reply moves onto its serial-string base
(0x75 = DS base + 1), fixing the pre-existing feature-vs-string mismatch.
* The Deck identity already did this per-pad; its two inline index reads
now share the new `pad_index()` helper.
Pad 0 keeps today's serial values for DS / DS4 / Deck (no identity churn
for existing single-pad setups).
Verified on the windows-amd64 runner: cargo build + clippy -D warnings
(pf-umdf-util / pf-xusb / pf-dualsense) + fmt clean on the pinned 1.96.0.

Root-cause fixes for "rumble + adaptive triggers never work with Linux hosts"
(the capture code itself was proven good on-hardware — see the new tests):
* 60-punktfunk.rules now grants the `input` group the VIRTUAL pads' hidraw
nodes (DS/Edge/DS4/Switch/Deck/SC). Steam/SDL drive DualSense adaptive
triggers, lightbar, and player LEDs exclusively over hidraw — and Steam
without hidraw demotes a PlayStation pad to a generic evdev device, losing
its rumble handling too. Coverage no longer depends on the distro's
steam-devices rules + logind's active-seat uaccess ACL (which a headless/
dedicated streaming session never gets). Verified live: nodes now come up
root:input 0660.
* Per-pad MAC in the DualSense (0x09) and DS4 (0x12) pairing feature replies:
hid-playstation adopts the MAC as the HID uniq and SDL/Steam dedup
controllers by that serial — identical MACs made a second virtual pad read
as the first one re-connecting over another transport.
* DualSense/DS4 UHID backends now ack UHID_SET_REPORT (err=0) instead of
ignoring it, so a SET_REPORT writer no longer blocks on the kernel's 5 s
timeout.
* New #[ignore] on-box tests play the GAME's role against a real kernel and
pin the full feedback surface (all green on real hw): DualSense evdev-FF +
raw hidraw output report (rumble/lightbar/LEDs/both trigger blocks verbatim,
per-pad uniq), uinput X-Box FF upload→pump→stop-on-erase, and usbip Deck
0xEB rumble via the controller interface (idle interfaces ACK silently,
like real hardware).
Windows note: the UMDF driver keeps its own pairing blob copies — the shared-
MAC dedup hazard exists there too and needs a driver-side follow-up.

Steam validates the Deck unit serial's format before accepting it. Our
"PFDK..." serial was REJECTED ("Invalid or missing unit serial number"), so
Steam substituted a hash identity and mangled the displayed name to
"Steam Deck Controllerggg" on every host tested. An 'F'-leading serial passes,
so switch to "FVPF..." — keeps the PunktFunk marker one slot in, still distinct
from a real Deck's "FVZZ..." for the Linux self-detection in
physical_steam_controller_present(). The name now shows a clean "Steam Deck
Controller" with a serial-derived handle (verified on .173).
Also fix the UMDF driver's 0xAE GET_STRING_ATTRIBUTE handler to echo the
requested attribute id faithfully instead of collapsing board-serial (0x00)
requests to unit-serial (0x01). Steam still logs a benign "Deck Controller PCB
Serial# invalid" for the board serial — it validates that against a
Valve-internal format for ANY value, including an empty one (verified) — but
that line does not mangle the name, change the handle, or block promotion.
Applied to both transports: host inject/proto/steam_proto.rs::deck_serial
(Linux gadget/usbip) and the pf-dualsense UMDF driver (Windows), which mirror
each other's serial format.

The N4 GO verdict, productized. GamepadPref::SteamDeck on a Windows host
now builds a real virtual Deck instead of folding to DualSense: games
get native Deck glyphs + both trackpads + gyro + all four back grips
through Steam Input's own remapping.
- steam_deck_windows.rs: DeckWinPad/DeckWinProto/SteamDeckWindowsManager
over the sealed shm channel, sharing the whole Linux Deck codec
(steam_proto now compiles on Windows too — it was already pure). The
SwDevice identity carries usb_mi: Some(2): the &MI_02 hardware-id
token hidclass mirrors into the HID child and Steam parses as the
wired controller interface — the promotion gate.
- Driver: DEVTYPE_STEAMDECK (3) graduates from the spike — SET_FEATURE
0xEB rumble / 0x8F haptic pulses are republished to the host through
the output slot (report-id-0 prefixed, so parse_steam_output sees the
Linux wire shape), and the 0xAE/GET_STRING serial + 0x83 unit id are
per-pad (read from the section's pad_index; PFDK<unit-id> matches
steam_proto::deck_serial).
- Router: SteamDeck arms in the Windows Pads paths; pick_gamepad flips
SteamDeck-if-windows -> SteamDeck (the DualSense fold retires);
dualsense-windows-test grows --deck.
ON-GLASS VALIDATED on .173 (rebuilt signed driver 9.9.0714.12xx
installed, Steam live): the manager-created pad (index 1) enumerates
with per-pad serial PFDK50460001, Steam logs Interface: 2 ->
'!! Steam controller device opened' -> 'Steam Controller reserving
XInput slot 0' -> PollState 2 (actively polling our cycling input
frames) -> mapping activated; clean teardown on exit. Rumble round-trip
through a real game remains an on-glass debt (nothing sent 0xEB during
the idle hold).
Known gap vs Linux: no physical-Steam-controller conflict degrade on
Windows yet (degrade_steam_on_conflict is Linux-only — /sys scan); a
Windows equivalent needs SetupDi enumeration and is deferred.

The gamepad-new-types §6 go/no-go rig, ready to run the moment .173 is
back (the box is currently down, so the observation itself is still
owed): does Steam Input on Windows promote a software-devnode HID Deck
(28DE:1205), or does it need a real USB bus identity (the documented
GameInput instance-path gap — the Linux 'Interface: -1' lesson)?
- Driver: scratch device_type=3 serves the Deck identity — the captured
38-byte controller-interface descriptor, 28DE:1205 attributes, Valve
strings, the Deck neutral frame, and the Steam 0x83/0xAE feature
contract (SET_FEATURE latches the command, GET_FEATURE answers it —
attribute blob + unit serial mirroring steam_proto::feature_reply).
Never stamped by a session. INF gains pf_steamdeck.
- Host: deck_spike_hold() + the `deck-windows-spike` subcommand — stamps
devtype 3, spawns the devnode under VID_28DE&PID_1205, streams the
neutral frame, prints what to observe (Steam logs/controller.txt,
controller settings) and logs any output reports Steam writes.
Run recipe (on .173, once the updated signed driver is staged): install
driver, start Steam, `punktfunk-host.exe deck-windows-spike`, watch
controller.txt. GO -> plan a proper N4 phase (the Deck codec is already
shared); NO-GO -> document next to the Linux Interface:-1 note and keep
the SteamDeck->DualSense Windows fold.
Verified: .133 clippy -D warnings + the driver workspace cargo check
(WDK) both green; .21 clippy + 304/0 tests unaffected.

The virtual Steam Deck pad only appears in the host's Game Mode (and is
navigable) when it arrives as a real USB device via the usbip/vhci_hcd
transport — Steam Input won't promote the UHID hid-steam fallback
(Interface: -1). The host runs as an unprivileged --user service, so it
cannot modprobe vhci_hcd itself; the module must be loaded at boot and the
vhci attach/detach sysfs files chgrp'd to the `input` group by the udev
rule.
Packaging ships modules-load.d/punktfunk.conf + 60-punktfunk.rules under
the sysext's /usr/lib, but a systemd-sysext image MERGES after
systemd-modules-load and early udev have already run, so on a plain reboot
of a sysext host (e.g. Bazzite) those files are read too late: vhci_hcd is
never loaded, usbip fails, and the pad silently degrades to non-promoted
UHID — the controller vanishes from Game Mode. (deb/arch/rpm are
unaffected: real /usr is present at early boot.)
Fix: sysext post_merge now mirrors BOTH files into real /etc (read at the
normal early-boot time, shadowing the /usr copies by filename; refreshed
every merge since neither is user config), then reloads udev, modprobes
vhci-hcd, and re-triggers the vhci platform device for the live session.
Also raise the UHID-fallback log INFO->WARN with an actionable hint.
Verified on the .41 sysext host: after the /etc mirror, unloading vhci_hcd
and restarting systemd-modules-load (the real reader of /etc/modules-load.d)
reloads the module; a udev coldplug trigger makes attach/detach root:input
0660; the unprivileged host user can then write attach — the exact working
precondition for the usbip transport, now durable across reboot.

When a second client got its own virtual display mid-stream, the FIRST
client's IDD-push stream froze (video only; `new_fps=0 repeat_fps=240`
forever). Adding/removing/resizing a sibling display re-commits the CCD
topology, which makes the OS unassign+reassign the first monitor's IddCx
swap chain. `unassign_swap_chain` dropped the SwapChainProcessor, dropping
`run_core`'s local FramePublisher and closing the sealed-channel handles.
The fresh worker then polled the frame-channel stash — but that stash is
consumed once at session open, and the host only re-delivers on a ring
recreate (a descriptor change). The first monitor's descriptor didn't
change and WUDFHost stayed alive, so no watchdog fired: the driver drained
the swap chain without publishing and the host repeated its last frame
indefinitely. Confirmed twice on the .173 box (host.log 21:12 & 21:15).
Preserve the live FramePublisher across the flap instead of dropping it:
the host-owned ring (header/event/textures) it holds stays valid — only
the swap chain died.
- frame_transport.rs: FramePublisher records its render-adapter LUID +
exposes render_adapter().
- monitor.rs: MonitorObject.preserved_publisher + preserve_publisher()
(mirrors set_frame_channel) + take_preserved_publisher() (mirrors
take_frame_channel). Monitor teardown drops the stashed publisher and
closes its ring handles, so nothing leaks.
- swap_chain_processor.rs run_core: after SetDevice OK, re-adopt a
preserved publisher ONLY when the new swap chain renders on the same
LUID (same pooled Direct3DDevice → its context + opened textures are
valid); on loop exit, stash the publisher back on the monitor.
Safe: the old worker is fully joined (drop-outside-lock discipline)
before the new one runs, so no concurrent context use; a stale re-adopted
publisher is superseded by the existing is_stale() + has_frame_channel()
newest-wins checks at the loop top.
Verified clippy -D warnings clean on rustc 1.96.0 via a faithful mock
crate (the real crate needs the WDK to compile). Needs a driver rebuild +
reinstall on the host to take effect; not yet hardware-validated.

On-glass validated 2026-07-12 on an AMD RADV 780M with a real Deck-class
client: the pipelined raw-Vulkan HEVC encoder ran a rock-solid 1080p@240
session and healed loss with clean P-frame recovery anchors (real RFI the
libav VAAPI path can't express). Ship it on by default, mirroring the NVENC
default-on.
- vulkan_encode_enabled() defaults ON; PUNKTFUNK_VULKAN_ENCODE=0 is the libav
VAAPI escape hatch. A failed open still falls back to VAAPI, so a device
without h265 Vulkan encode (or an untested Intel/ANV that misbehaves at open)
degrades gracefully instead of breaking the stream.
- Ring depth defaults to 2 (one frame of overlap, lowest added latency — the
on-glass-validated real-time setting); PUNKTFUNK_VULKAN_INFLIGHT still tunes it.
- Compile --features punktfunk-host/vulkan-encode into the arch/deb/rpm host
builds (pure-Rust ash, no new lib / no link-time dep), alongside nvenc.

On-glass validated 2026-07-12 on an RTX 5070 Ti host with a real Steam Deck
client (NV12 4:2:0, 1280x800@90): real nvEncInvalidateRefFrames landed 73/73
as clean P-frame recovery anchors (never IDR), losses consistently ~2 frames
deep — well inside the 5-frame DPB. That is the loss recovery the libav
hevc_nvenc path cannot express, so make the direct path the default on NVIDIA.
PUNKTFUNK_NVENC_DIRECT=0 (also false/no/off) is now the libav escape hatch.
Still gated on a CUDA capture payload — the `cuda` check in open_nvenc_probed
keeps AMD/Intel on VAAPI regardless, and the NVENC/CUDA entry points stay
dlopen'd at runtime (no new DT_NEEDED), so non-NVIDIA hosts are unaffected.
Packaging comments updated to match.

The Phase 5.2 direct-SDK NVENC Linux backend (encode/linux/nvenc_cuda.rs) is
gated `#[cfg(all(target_os = "linux", feature = "nvenc"))]`, but no Linux
packager passed `--features nvenc` (it was historically a Windows-only feature
for the D3D11 NVENC path). So the module was compiled OUT of every arch/deb/rpm
canary regardless of commit — PUNKTFUNK_NVENC_DIRECT was a silent no-op on the
shipped Linux host. Add `--features punktfunk-host/nvenc` to all three package
builds so the code actually ships.
AMD/Intel-SAFE (verified): this is NOT the old Windows link-import crash. The
NVENC/CUDA entry points are dlopen'd at RUNTIME (libloading) — `objdump -p` shows
the feature build's DT_NEEDED is byte-identical to a plain build (no libcuda /
libnvidia-encode), so the binary starts fine driver-less. We use only the crate's
`sys::nvEncodeAPI` types (no code-running safe wrapper / lazy statics), cudarc
stays on `ci-check`/dynamic-loading (no CUDA toolkit at build), and the encoder is
only constructed for a CUDA capture frame + PUNKTFUNK_NVENC_DIRECT — never on a
VAAPI (AMD/Intel) host. The sysext images repackage these outputs, so they inherit
it; no other Linux host build compiles the binary.

The punktfunk-web unit serves HTTP/1.1 over TLS with the host's own
self-signed identity cert, but several guides still told users to open
http://<host>:47992, which fails. Correct the scheme everywhere and note
the one-time browser cert warning in the canonical + SteamOS docs.
The RPM %post web hint was doubly wrong (http://<host-ip>:3000): wrong
scheme and wrong port — the service listens on :47992, not the :3000 dev
default. Also fixes scripts/web-init.sh, so the URL the SteamOS/Linux
installer prints at the end of setup is correct too.

The Vulkan-layer env vars alone left hdr10_format=None on a Deck OLED: the
FROG gamescope WSI layer loads but must open a Wayland connection to
gamescope's private socket ($GAMESCOPE_WAYLAND_DISPLAY = gamescope-0) to
negotiate HDR10 via the gamescope_swapchain protocol. The Deck runs games as
X11 clients, so --socket=wayland binds nothing and that socket never enters the
sandbox → the layer silently can't reach the compositor → PQ tone-mapped to
SDR, badge dark. Bind xdg-run/gamescope-0 (as chiaki-ng does); with the layer
path + ENABLE_GAMESCOPE_WSI + the socket, the surface offers HDR10 and the
presenter's existing HDR10 swapchain path engages — no client code change.
Harmless off-Deck (the layer no-ops with no gamescope socket to bind).

design/windows-parallel-virtual-displays.md (display-management Stage 7 / §6.6): N
simultaneously-live pf-vdisplay monitors, one sealed ring each, every idd-push-security
invariant preserved per-ring.
- proto v3: SharedHeader._pad → target_id — the ring NAMES its monitor, host-stamped
before the magic; the driver publisher refuses a cross-bound ring via the shared,
unit-tested frame::check_attach (new DRV_STATUS_BIND_FAIL — the gamepad pad_index
validation applied to frames, invariant #10); the host's wait_for_attach surfaces the
refusal loudly and self-checks its own stamp.
- manager: the one-monitor MgrState becomes a slot map keyed by the client's identity
slot (0 = anonymous/GameStream); per-slot reconnect + dead-WUDFHost preempts,
slot-scoped begin_idd_setup (a different identity is an admission question, never a
preempt), ONE device-level watchdog pinger, per-slot /display/state + /display/release.
- group topology: isolate_displays_ccd takes the managed target SET (a sibling slot is
never deactivated); SavedConfig + the DDC/PnP axes move to the group record (first-in
captures, last-out restores); desktop layout via CCD source origins from the pure
layout::arrange (auto-row default, manual pins win), re-applied on create + reconfigure.
- admission: the Windows separate→reject override now sits behind the
PUNKTFUNK_WIN_SEPARATE=1 validation hatch (the wedge it guarded is structurally gone —
a second identity gets its own monitor + ring; default flips in W5 after soak);
max_displays and NVENC session-unit budgets decline an unaffordable display AT
admission; kick_dwm_compose is process-globally throttled and per-display — cursor
jump + 35 ms dwell (a sub-tick jump composes nothing; DWM reads dirties from current
state at the next vsync tick).
On-glass on the RTX box: V1/V2/V4/V5/V6/V9 green — two paired clients on two monitors
streaming ~60 fps each with zero mismatches and zero bind failures, churn-hammer clean
(no 0x80070490), per-ring mode-change recreate leaves the sibling untouched, typed
budget rejection, fault-injected cross-bind refused loudly with the sibling undisturbed.
V7: WUDFHost-kill shared fate is clean; in-process device recovery is a known follow-up
(the retired-never-closed control handles block the adapter cycle — reset-pf-vdisplay.ps1
recovers). DWM composes two IDD monitors concurrently at 60 fps — the plan's
load-bearing unknown, answered yes.
Also carries the client-HDR EDID forwarding that shared this working tree
(Hello::display_hdr → AddRequest luminance tail → the monitor's CTA-861.3 HDR block,
PUNKTFUNK_CLIENT_PEAK_NITS hatch) and the Deck client fixes (40 ms rumble keep-alive
with 1-LSB jitter, HDR self-diagnosing presenter warn, flatpak HDR env).

Six parallel audits swept the root docs, docs-site, every per-directory
README, and the packaging docs; every claim below was verified against
the source before editing.
- README: Layout gains the six missing crates (pf-client-core,
pf-presenter, pf-console-ui, pf-ffvk, pf-driver-proto, punktfunk-tray),
clients/session, api/ and ci/; Linux/Windows client rows reflect the
shell + Vulkan-session split and the Vulkan Video -> VAAPI/D3D11VA ->
software decode chains; the "every client over a C ABI" claim is
corrected (Rust clients link the core directly); tiered stats overlay
+ console shell noted; Apple row mentions AV1.
- CONTRIBUTING: drop the dead CLAUDE.md link (deliberately untracked);
point at the README's build/invariants sections. SECURITY: 0.9.0.
- host-cli/pairing: --allow-pairing/--require-pairing are no-op legacy
names — pairing is required by default, --allow-tofu is the real flag;
document --data-port and --idle-timeout-ms.
- configuration: document PUNKTFUNK_RECOVER_SESSION_CMD (session-crash
recovery hook), PUNKTFUNK_MDNS, PUNKTFUNK_DATA_PORT.
- virtual-displays/gnome: GNOME per-client scaling shipped (host-
persisted) — flip the ❌ to ✅ and describe how it works.
- stats: new "Detail levels" section (Off/Compact/Normal/Detailed +
per-platform cycle gestures); retire the GTK hand-off note.
- clients/install-client/status/roadmap: decode chains, Windows client
validation narrowed to HDR-only pending, adaptive bitrate, console
shell, Apple AV1, Windows host vendor list.
- Sub-READMEs: clients/linux rewritten for the re-architecture; session
Windows decode rung + d3d11va knob; Windows tiered overlay; Android
minSdk 28; decky file table; host zerocopy/ path; scripts port
47992 and steamos-host.md; pf-dualsense source path.
- packaging: canary version bases are tag-derived (<next-minor> via
pf-version.sh/.ps1), codecs-extra not ffmpeg-full, document the
pinned offline-Skia tarball + SKIA_BINARIES_URL and vulkan-headers.
- Convert 15 dangling design/*.md links to the punktfunk-planning
prose convention (those docs live in the private planning repo).

The flatpak's offline cargo build has failed on every run since the D3D11VA push:
pf-client-core now declares the same git-pinned `windows` dependency as the Windows
client (cfg(windows)-gated, never compiled on Linux), and `cargo --offline` needs
every DECLARED dependency's source just to build the unit graph — but windows-rs is
deliberately not vendored into cargo-sources.json (flatpak-builder would full-clone
the multi-GB repo; the reason prune-windows-lock.py exists). Removing the workspace
member alone no longer covers it.
New packaging/flatpak/prune-windows-toml.py (dependency-free, like its lock sibling)
strips windows-rs git entries from a manifest in place — single- or multi-line —
and the flatpak manifest runs it on crates/pf-client-core/Cargo.toml right after the
existing clients/windows member sed. Registry deps in the same cfg(windows) table
(wasapi, sdl3) are kept; they vendor normally.
Verified in a scratch worktree with both prunes applied: the TOML stays valid and
`cargo metadata` resolves ZERO windows-rs packages and zero git-source declarations
— nothing left for --offline to fetch. End-to-end proof is the flatpak CI run on
this push.

Steam Input only adopts the virtual Steam Deck controller when it arrives as
a real USB device (raw_gadget or usbip/vhci transports); the UHID fallback
has no USB interface and Steam ignores it. On a stock host neither
precondition for usbip held: vhci-hcd isn't loaded, and its sysfs
attach/detach files are root-only while the host runs as a user service —
so every session silently fell back to UHID and 'no controller appears on
the host' (live-debugged 2026-07-08: client events all arrived, the pad
existed, Steam just refused it).
Ship both preconditions with the host packages:
* modules-load.d/punktfunk.conf loads vhci-hcd at boot (rpm/deb/arch;
Bazzite gets it via the RPM payload + a modprobe in the sysext
post-merge hook)
* a udev rule in 60-punktfunk.rules grants the input group write on
vhci_hcd's attach/detach whenever the device appears
Verified end-to-end on a live host: usbip in-process attach, hid-steam
binds all three interfaces, 'Steam Deck' + motion evdev appear, and Steam
adopts the pad (client-mode grab + its own virtual X360 emission).

The RPM %files %doc referenced design/implementation-plan.md, but the design/

so rpmbuild failed at %files ("File not found: .../implementation-plan.md") once
the build got that far. Ship the two docs that actually exist (README.md +
packaging/README.md). Pre-existing spec rot, surfaced by the 0.8.3 release run.

The re-architecture split the Linux client into two binaries (shell + Vulkan
session streamer) and added the pf-ffvk crate, whose build.rs runs bindgen over
FFmpeg's libavutil/hwcontext_vulkan.h (#include <vulkan/vulkan.h>). Two release
regressions fell out of that on the desktop-package legs:
1. Missing build dep. The Arch build (archlinux:base-devel + its own pacman list)
fatal-errored at `vulkan/vulkan.h file not found`. Add the Vulkan dev headers
wherever the client compiles from a self-managed dep set: arch (PKGBUILD
makedepends + arch.yml), rpm (spec BuildRequires + rpm.yml + fedora image),
deb.yml (belt-and-suspenders; the rust-ci image already bakes libvulkan-dev),
and the screenshots job. The flatpak builds offline against the GNOME SDK, so
install Vulkan-Headers into /app as a pinned module and point pf-ffvk's bindgen
at it via PF_FFVK_VULKAN_INCLUDE.
2. Only the shell shipped. arch/deb/rpm built and installed just punktfunk-client;
the shell execs its sibling punktfunk-session for a connect, so desktop
streaming would break exactly as Decky's did. Build and install BOTH binaries
in all three, and declare the runtime Vulkan loader the session binary dlopens
(vulkan-icd-loader / vulkan-loader / libvulkan1 — not a DT_NEEDED, so
shlibdeps/auto-requires can't see it).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The re-architected Linux client is now two binaries: the punktfunk-client shell
execs its sibling punktfunk-session (ash/Vulkan presenter + Skia console UI) for
--connect/--browse. The Decky plugin's stream and browse paths launch the shell
with exactly those flags, but the flatpak built and installed only the shell, so
streaming and the gamepad library from the Deck failed at exec with
"punktfunk-session: No such file" (pair/wake/library still worked — the shell
handles them in-process).
Build and install both binaries. The session binary pulls in Skia (skia-safe),
whose build script downloads a prebuilt libskia — dead in the offline sandbox —
so point skia-bindings at a pinned, vendored archive via SKIA_BINARIES_URL=file://
(read directly, no curl); the tarball rides along as a sha256-pinned flatpak
source. Widen the flatpak CI path filters to the session binary's crates
(linux-session, pf-presenter, pf-console-ui, pf-client-core) and fix the moved
library.rs path in the Decky error-classifier comment.
All other plugin↔client contracts (flags, pairing/library output, config files,
env vars, exit codes, the 47990 mgmt port) already match — no changes needed.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The mgmt REST API has bound 0.0.0.0:47990 by default since ae51276 so paired
clients can browse the game library over mTLS, but every packaged firewall
opener still excluded 47990 and the docs still claimed it was loopback-only.
On any host with an active firewall (ufw/firewalld) the LAN game-library
feature was silently broken.
Add 47990/tcp to the native firewall profiles (punktfunk.ufw [punktfunk-native]
+ punktfunk-native.xml) and correct the stale "loopback-only by default" text
across the debian/arch/bazzite READMEs and the docs site (incl. the factually
wrong --mgmt-bind default in host-cli.md, 127.0.0.1 -> 0.0.0.0). Opening the
port adds no admin exposure: off-loopback mgmt::require_auth serves only the
read-only status/library allowlist to a paired client cert; the bearer-token
admin surface stays loopback-only regardless of the bind.
Windows was already sound (shared parse_serve binds 0.0.0.0; service.rs already
firewall-opens 47990) — add a clarifying comment so the rule isn't mistaken for
accidental over-exposure.

Now that the per-capture worker subprocess makes an NVENC EGL/CUDA driver
fault survivable (design/zerocopy-worker-isolation.md), the reason the NVENC
zero-copy path stayed opt-in is gone. zerocopy::enabled() now defaults ON for
both GPU backends (was ON VAAPI / OFF NVENC). Fallbacks are intact: VAAPI's
one-shot CPU auto-downgrade (VAAPI-gated, never trips for NVENC) and NVENC's
per-capture fallback + worker-death latch.
Reframe the shipped host.env examples and setup guides to rely on the default
rather than force PUNKTFUNK_ZEROCOPY=1 (an explicit =1 skips the VAAPI
auto-downgrade).

CachyOS ships ufw enabled by default (firewalld is not installed) — verified live
on the .21 box — but the docs and shipped firewall openers claimed "CachyOS enables
firewalld by default". Correct that everywhere and ship a ufw application profile
(the one-liner analogue of the firewalld service files):
- packaging/linux/punktfunk.ufw (new): [punktfunk-native], [punktfunk-gamestream],
[punktfunk-web] profiles, installed to /etc/ufw/applications.d/punktfunk by the
Arch (CachyOS) and .deb host packages. `sudo ufw allow punktfunk-native`.
- packaging/linux/punktfunk-web.xml (new): firewalld service for the optional web
console (TCP 47992), installed by the host package on arch/deb/rpm. Neither the
native nor gamestream opener covered 47992, so a firewalld/ufw host that enabled
punktfunk-web could not reach the console over the LAN.
- Fix the "CachyOS enables firewalld" claim in arch.md, arch/README.md,
debian/README.md, both firewalld service .xml comments, and the pacman scriptlet;
firewalld now attributed to the spins that use it (EndeavourOS, Fedora/RHEL).
- Docs present both one-liners (ufw + firewalld) whichever firewall you run, plus a
console-opener step; postinst/scriptlet hints detect ufw as well as firewalld.
The native data plane stays hole-punched (ephemeral UDP, no fixed port) — its
openers correctly open only 9777/udp + mDNS; the stale "open a UDP range" note is
replaced with the accurate outbound-UDP explanation.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The native data plane used a random ephemeral UDP port (hole-punched), which a
strict firewall can't pre-open — so remote clients behind one couldn't connect.
Add an optional fixed data port:
- `Punktfunk1Options`/`NativeServe` gain `data_port`; `bind_data_socket` binds the
fixed port (→ direct, no hole-punch) or falls back to a random port + hole-punch
when unset or the fixed port is busy (a concurrent session already holds it).
- `UdpTransport::from_socket`/`from_socket_punch` adopt an already-bound socket, so
the host keeps the SAME data socket from handshake through streaming — no
drop-then-rebind window in which a concurrent session could steal a fixed port.
- `main.rs` wires the CLI flag through to `NativeServe`.
- Firewall docs updated (troubleshooting.md + apt/pacman/bazzite READMEs): control
plane is the fixed UDP 9777; the data plane is a separate random port that usually
needs no rule, with the fixed-port option for strict firewalls.
Unit-tested: default random+hole-punch, and fixed-port-then-fallback-when-busy.

Mirror the Arch firewalld service definitions into the RPM spec and the Debian
host package so every Linux packager installs them, and move the two XML files
to the shared packaging/linux/ home (alongside the .desktop files both the
PKGBUILD and deb scripts already source there) so there's one source of truth
instead of three drifting copies.
- rpm: install punktfunk-{gamestream,native}.xml to /usr/lib/firewalld/services/,
list them in %files host, and print the firewalld enable command in %post
(gated on firewall-cmd). Fedora/RHEL run firewalld by default, so this is where
it matters most; Bazzite inherits it via the sysext built from the package /usr.
- deb: install both XMLs in build-deb.sh and add the same firewalld-gated hint to
the postinst. Debian/Ubuntu ship no active firewall, so it's a no-op unless the
admin runs firewalld.
- PKGBUILD + arch README updated to the packaging/linux/ path.
- Firewall docs (bazzite README now leads with --add-service; debian README gains
a firewalld block) point at the shipped services; XML comments made
distro-neutral. Never auto-enabled — packages don't touch the admin's firewall.

The pacman-repo setup step used a bash heredoc (`<<'EOF'`), which fish — the
default shell on CachyOS — cannot parse ("expected a string, but found a
redirection"). Replace it with a cross-shell `printf | sudo tee -a` form in both
the Arch guide and packaging/arch/README.md; `$repo`/`$arch` stay literal for
pacman and the output is byte-identical to the old heredoc.
Firewall: stock Arch ships none (ports already open), but CachyOS enables
firewalld by default and an Arch package must never touch the running firewall.
Ship firewalld service definitions the host package installs to
/usr/lib/firewalld/services/ (punktfunk-gamestream, punktfunk-native), not
auto-enabled; the install scriptlet prints the enable command only when
firewall-cmd is present. Document it in the Arch guide (new section) and README.
The mgmt API (loopback) and web console ports are deliberately not opened.
Also fix the "GTK4 couch/Deck client" mislabel — it's the native
GTK4/libadwaita Linux client (desktop/laptop/Deck are targets; the
controller-optimized launcher is one view, not its identity) — across the Arch
PKGBUILD/README, Arch guide, and the Debian README.

The Gitea Arch registry signs its DB + packages, so 'SigLevel = Optional TrustAll' fails
non-interactively (pacman still needs the key to verify). Document the one-time
pacman-key import instead; install is then signature-validated under pacman's default
SigLevel (verified end-to-end: clean archlinux container -> repo sync -> install,
'Validated By: Signature').
Also cache /usr/local/cargo/git in arch.yml: the workspace pulls clients/windows'
git-pinned windows-reactor/windows deps to resolve, cloning windows-rs (huge) every run
otherwise — same registry+git cache deb.yml uses.

New arch.yml builds the split PKGBUILD (host/client/web, PF_WITH_WEB=1) in an
archlinux:base-devel container on every push and publishes to the pacman repos
'punktfunk' (tags) / 'punktfunk-canary' (main, X.Y.Z-0.<run#> — pkgrel allows
only digits+dots, so the run number carries the ordering). Consumers add one
pacman.conf section; no more build-it-yourself as the only Arch path.
PKGBUILD: pkgver/pkgrel env-driven (PF_PKGVER/PF_PKGREL), source=() when
PF_SRCDIR is set (a canary version has no tag to clone), stale NVENC-only
header fixed, and options=('!lto' '!debug') — makepkg's lto option injects
-flto=auto into CFLAGS, aws-lc-sys compiles its C with it, and rust's lld
cannot read GCC LTO bitcode: 'undefined symbol: aws_lc_*' at link (reproduced
minimally on Arch + rust 1.90). Full build + clean-container install
smoke-tested locally (binaries run, payload + scriptlets intact).

Layering is a last resort per the Bazzite docs (slows every OS update, can
block upgrades until removed); a sysext never enters an rpm-ostree
transaction, survives OS updates, and installs/updates with no reboot —
the mechanism Fedora Atomic ships via fedora-sysexts.
- build-sysext.sh wraps the built host+web RPMs into punktfunk-<V-R>-x86-64.raw:
/etc payload relocated to /usr/share/punktfunk/etc (a sysext carries only
/usr), the punktfunk-sysext helper embedded, ID=fedora + VERSION_ID pinned
(merges on Bazzite via ID_LIKE; REFUSED after a major rebase instead of
running soname-broken binaries — both behaviors validated live on Bazzite 43).
SELinux labels are baked in as squashfs pseudo-xattrs from matchpathcon:
unlabeled files run fine for user units but system daemons are DENIED
(udev couldn't read the gamepad rule under enforcing) — validated on-glass.
Refuses duplicate input package names (a stale noarch punktfunk-web next to
the x86_64 one built a chimera image with the dead node launcher once).
- punktfunk-sysext.sh: install/update/status/remove against per-Fedora-major
feeds (…/generic/punktfunk-sysext/f43[-canary]), SHA-256-verified, applies
the udev/sysctl scriptlet work + /etc copies, prints the layering-migration
hint. Live-validated on the .41 Bazzite box incl. service restart + web console.
- publish-sysext-feed.sh + rpm.yml: build + publish the image per matrix leg
(fedver 43/44), canary feeds pruned to 6, stable release assets attached.
- update-punktfunk.sh warns when the sysext shadows a layered install.

The v0.7.2 flatpak build failed: `error: Unknown socket type pipewire` — this
flatpak-builder toolchain (and the Deck's flatpak 1.16 override CLI) don't
accept --socket=pipewire. --filesystem=xdg-run/pipewire-0 binds the same native
socket and is the portable form already validated on-Deck (pipewire-0 appears
in the sandbox, client audio node registers, no pw-connect error). Keep only
that + --socket=pulseaudio.

The Linux client speaks the native PipeWire protocol (audio.rs `pw connect`),
but the manifest granted only --socket=pulseaudio, so the sandbox had just
`pulse/native` and no `pipewire-0`. Playback + mic both died with
"pw connect (is PipeWire running in this session?)" — reproduced live on a
Steam Deck in Gaming Mode (no client audio node ever appeared).
Add --socket=pipewire (canonical) + --filesystem=xdg-run/pipewire-0 (portable
bind of the same socket). Validated on-Deck via a `flatpak override
--filesystem=xdg-run/pipewire-0`: pipewire-0 then appears in the sandbox and
the client registers its "punktfunk-client" PipeWire node with no pw-connect
error.

`rpm-ostree upgrade` re-resolves layered packages only when the BASE image
changes; on a frozen Bazzite base (pinned :stable tag / paused rebase) it
reports "No updates available" and never bumps the layered punktfunk even
when newer RPMs are live in the repo — observed on the .41 host stuck at
0.6.0 while 0.7.x sat in the registry.
- Add packaging/bazzite/update-punktfunk.sh: detects the layered punktfunk
packages, refreshes rpmmd, and forces a re-resolve via
`rpm-ostree update --uninstall <pkg> --install <pkg>` (the one-transaction
idiom that actually pulls a new layered version on a static base).
- Document the trap + the fix in packaging/bazzite/README.md, including the
channel gotcha: an enabled punktfunk-canary.repo (<next-minor>.0-0.ciN)
outranks stable X.Y.Z-1, so the box silently tracks canary — enable one
channel only.

Batch B of the audit's medium tier (M4+M5+M6):
- M4: adapter_init_finished now reads AdapterInitStatus (was ignored) and
only stashes the adapter on NT_SUCCESS, per the MS sample. A failed async
init previously produced a HUSK adapter: monitors created on it arrive
but the OS never assigns a swap-chain — every session black-screens with
no visible cause (the exact signature live fault-injection produced after
a WUDFHost kill). Unset adapter → ADD fails cleanly (host-retryable) and
a re-entrant D0 retries the init; the status is now in the debug log.
- M5: pooled_device checks GetDeviceRemovedReason on a cache hit — a TDR'd
device was returned for its LUID forever (SetDevice fail-loop, black
virtual display until device teardown); now it falls through to a fresh
create.
- M6: an AvSetMmThreadCharacteristicsW failure no longer aborts the worker
before draining (which stalled the monitor and leaked the WDF swap-chain
object) — continue unprioritized like the MS sample; revert only if MMCSS
actually engaged.
