enricobuehler 85e8400028 feat(vdisplay): KWin per-slot output naming for persistent scaling (Stage 3)
The KWin backend names its output Virtual-punktfunk-<id> from the client's
stable identity slot, so KWin persists per-output config (scale/mode) by name in
kwinoutputconfig.json and reapplies that client's scaling on reconnect — the KDE
scaling ask. Also fixes the latent clash where two concurrent sessions both used
Virtual-punktfunk (topology name-matching now uses the per-slot name).

- identity::global() + resolve_slot(fp, mode, default) — the shared persisted map
  (Windows manager dropped its own field; both use the global — never same-process).
  Default identity is per-platform: PerClient on Windows, Shared on Linux, so
  unconfigured hosts keep today's behavior (Linux = single 'punktfunk' name).
- KwinDisplay carries the client fp (set_client_identity), computes the per-slot
  name, threads it through the stream_virtual_output name + the topology helpers
  (set_custom_refresh / apply_virtual_primary[_only] / other_enabled_outputs).

enricobuehler b0bc15af8e feat(vdisplay): platform-neutral identity map + per-client-mode (Stage 3)
Generalize the Windows-only per-client stable-id map into vdisplay/identity.rs:
- DisplayIdentityMap keyed on a composable string (identity_key: fingerprint,
  or fingerprint+resolution under per-client-mode); LRU at 15, persisted to
  display-identity.json (migrated from the legacy pf-vdisplay-identity.json).
- Windows manager wired to it, picking the key from the identity policy.
- Foundation for KWin per-slot output naming (persistent KDE scaling) — the
  KWin wiring is the next Stage-3 step (needs a KWin box).
- Unit-tested (stable, per-client-mode split, LRU, key composition).

enricobuehler a0281289c0 feat(vdisplay): topology decoupling — distinct primary level (Stage 2)
The three topology levels become distinct behaviors (Stage 0 only did
extend-vs-exclusive, faking primary):
- vdisplay::effective_topology() -> the concrete level (console policy > legacy
  *_VIRTUAL_PRIMARY env > Auto default). Backends read it directly at create
  time; apply_session_env no longer writes the boolean env (one fewer connect-
  path env mutation).
- Mutter: extend (no config), primary (virtual primary + physicals kept as
  secondaries — build_primary_keeping_physicals), exclusive (sole, physicals
  disabled). KWin: extend (no-op), primary (kscreen primary only), exclusive
  (primary + disable others).
- Windows should_isolate treats primary as isolate (the primary-only CCD variant
  is a follow-up); wlroots exclusive + the physical-keep effect need a
  display-attached box (headless lab boxes can't observe primary vs exclusive).

enricobuehler 9d32cb58ee fix(vdisplay): call life.acquire() outside debug_assert (release no-op)
The pooled entry's lifecycle transition was inside debug_assert_eq!, whose
arguments don't evaluate in release builds — so acquire() never ran, the entry
stayed Idle, and release saw Noop → immediate teardown (no keep-alive). Caught
on-glass on the CachyOS box.

enricobuehler ed0881a9b9 feat(vdisplay): Linux keep-alive pool — registry-owned display lifecycle (Stage 1b)
The ownership split (design/display-management.md §3): the registry owns the
per-session virtual-display lifecycle on Linux, so a display can outlive its
session (keep-alive) and be reused on reconnect.

- registry.rs: a Linux pool driven by the pure lifecycle machine. acquire()
  reuses a kept (lingering/pinned) display of the same backend+mode, else
  creates one and keeps the backend's keepalive so the compositor output (and
  its PipeWire node_id) survives the session. The session's capturer holds a
  gen-stamped DisplayLease instead of the real keepalive; its drop drives
  linger/teardown. Enabling fact: KWin/Mutter/gamescope put their node on the
  DEFAULT PipeWire daemon (remote_fd=None) — reconnect re-attaches by node_id,
  no fd re-open. wlroots (remote_fd=Some, xdpw portal) passes through unchanged
  (teardown-on-drop) pending the fresh-portal-capture re-attach.
- Default (unconfigured) linger = Immediate → today's teardown-on-disconnect,
  so no behavior change without a keep-alive policy; concurrent sessions still
  each create their own output (reuse only matches LINGERING entries).
- Wired build_pipeline (punktfunk1) + gamestream through registry::acquire;
  capture_virtual_output signature unchanged. Windows delegates to vd.create
  (the manager already leases) — unchanged.

enricobuehler f818f1ec3d packaging: ship firewalld services on rpm + deb too, share from packaging/linux
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.

enricobuehler 8a06c7545b docs(arch): fish-safe repo setup, firewalld services, fix client label
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.

enricobuehler f79d5c5b49 fix(apple/macos): drop the rejected audioanalyticsd sandbox exception
App Review declined 0.4.2 (3384) under guideline 2.4.5(i): the temporary
com.apple.security.temporary-exception.mach-lookup.global-name =
com.apple.audioanalyticsd exception "is not appropriate and will not be
granted." It had been added on the theory that CoreHaptics controller
rumble (RumbleRenderer / MenuHaptics) hard-crashes under the App Sandbox
without it, since the framework reaches the audio-analytics daemon over
Mach and the sandbox denies that global-name lookup.

Tested the theory directly on macOS with a real Xbox pad: a
CHHapticEngine start + full-intensity rumble in a genuinely enforced
sandbox (NSHomeDirectory redirected into the app container) with no
exception on the codesigned binary runs fine — no crash — even with a
live AVAudioEngine stream running concurrently. CoreHaptics tolerates
the denied lookup; the exception was never load-bearing.

So just remove it: CoreHaptics session rumble and menu haptics keep
working on macOS unchanged (no source change needed). DualSense stays on
its raw-HID path — a genuine Sony-motor gap — which needs no exception
either.

Resubmit requires a new build number and clearing the App Store Connect
App Sandbox entitlement-usage justification for this exception.

enricobuehler b988053a31 feat(vdisplay): lifecycle state machine + display state/release API (Stage 1)
Stage 1 of design/display-management.md — the lifecycle core + the display
management surface:

- vdisplay/lifecycle.rs: pure per-slot state machine (Idle/Active{refs}/
  Lingering{until}/Pinned) with acquire/release/expiry/force-release
  transitions. No I/O, no OS types — the platform-neutral distillation of the
  Windows manager's model. Unit + a 200k-iteration seeded property walk
  (no leaks / double-frees / refcount underflow across arbitrary interleavings).
- vdisplay/registry.rs: neutral snapshot/release facade over the per-OS
  lifecycle owners. Windows reads/controls the VirtualDisplayManager; Linux
  keep-alive (a per-session pool) lands in a following increment (needs GPU-box
  validation).
- windows/manager.rs: additive snapshot() + force_release() (no behavior change
  to the on-glass-validated path).
- mgmt: GET /api/v1/display/state (live/kept displays) + POST /api/v1/display/release
  (tear down lingering/pinned now; refuses active). OpenAPI regenerated.
- web console: Virtual displays card gains a live-display list (polled) with
  per-row + release-all buttons and a linger countdown.

enricobuehler 21f3c1326f feat(vdisplay): display-management policy surface (Stage 0)
A user-configurable policy layer above the per-compositor VirtualDisplay
backends: keep-alive, topology, conflict, identity, layout, max-displays —
persisted to display-settings.json, editable from the web console, applied
per connect. Design: design/display-management.md.

Stage 0 stands up the surface and wires the two behaviors the existing code
can already express — the Windows monitor linger duration and the
"make the streamed output the sole desktop" topology — through it; every
other option is stored + echoed but not yet enforced (later stages). An
unconfigured host (no display-settings.json) keeps today's exact behavior.

- vdisplay/policy.rs: pure DisplayPolicy + 5 presets + JSON store (gpu-settings
  pattern) + EffectivePolicy; 9 unit tests.
- vdisplay.rs: resolve_topology(Auto); apply_session_env drives *_VIRTUAL_PRIMARY
  from the policy only when a settings file exists.
- windows/manager.rs: linger_ms() + should_isolate() read the policy when configured.
- mgmt: GET/PUT /api/v1/display/settings (bearer-only); PUT rejects keep_alive
  forever until the lifecycle stage. OpenAPI regenerated.
- web console: Host → Virtual displays card (preset picker + custom fields); en+de.
- docs-site: virtual-displays.md + configuration.md cross-links.

enricobuehler dd4e2d4fa8 fix(packaging/arch): correct pacman setup — import the registry key, cache cargo git
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.

enricobuehler b622e53dc1 feat(packaging/arch): distribute binary packages via the Gitea Arch registry
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).

enricobuehler f299aaeb3d feat(packaging/bazzite): systemd-sysext replaces rpm-ostree layering as the primary install path
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.

ABI_VERSION was doing double duty: the embeddable C surface AND the punktfunk/1
Hello/Welcome version that hosts equality-check. The WoL feature's v3 bump added
a client-local FFI function without changing a single wire byte — and every new
client started refusing against every deployed host ("ABI mismatch: client 3
host 2", observed live Deck → Bazzite). The wire now carries its own
WIRE_VERSION (still 2); ABI_VERSION stays 3 for the C header and the mgmt API's
informational field. Bump WIRE_VERSION only when the handshake/planes actually
change incompatibly.

The notarized Developer ID .dmg was SIGKILLed at launch ("Launchd job spawn
failed", POSIX errno 163) before main() ran: the sandboxed macOS app declares
the MANAGED keychain-access-groups entitlement, which AMFI only honors when an
embedded provisioning profile authorizes it. The DMG embedded none — App Sandbox
and the network/device keys are self-asserted for Developer ID, but a keychain
access group is not — so every launch was killed at spawn. Validly signed and
notarized (Gatekeeper accepted it), which is why this looked like a mystery. ⌘R
and the App Store build hid it: Xcode embeds a development / App Store profile;
the raw-codesign DMG path did not, so "⌘R == DMG" never held for this entitlement.

Embed a "Punktfunk macOS Developer ID" profile (Keychain Sharing) into
Contents/embedded.provisionprofile before codesign so its entitlements authorize
the access group, exactly like the App Store build's profile does. If the profile
isn't installed on the runner, warn and strip keychain-access-groups instead so
the app still launches via ClientIdentityStore's legacy file-keychain fallback —
a missing/expired profile can never reship the errno-163 brick again.

enricobuehler b37c48b32d feat(client-linux): in-process GL presenter — hardware decode ships on the Steam Deck
VAAPI decode stays; what changes is who touches the YUV. The direct path hands
the NV12 dmabuf (tiled AMD modifier since Mesa 25.1) to GdkDmabufTexture, and
GTK's tiled-NV12 import renders corrupt/gray/washed-out on the Deck. Moonlight
and mpv are clean on the same box because they import the dmabuf into their own
EGL context and convert with their own shader — video_gl.rs is that
architecture for the GTK client: per-plane EGLImages (R8 + GR88, modifier
passed through) → our YUV→RGB shader (matrix/range from the stream's CICP
signaling, unit-tested) → RGBA texture in a GdkGLContext-shared context →
fence-synced GdkGLTexture. GTK composites plain RGBA; no YUV negotiation, no
compositor CSC.

The Deck's decoder default flips back to hardware (the software stopgap is
gone); desktops keep the direct dmabuf path (offload/scan-out eligible).
PUNKTFUNK_PRESENT=direct|gl overrides either way. New failure ladder: GL
converter init failure or a convert-error streak raises a shared flag and the
session pump demotes the decoder to software with a keyframe re-request — the
same mechanism also closes the old silent-black-screen gap where a rejected
dmabuf import had no recovery at all.

enricobuehler fb709d68ce feat(clients): Wake-on-LAN in apple/linux/windows/android/decky
Each client learns a host's MAC from the mDNS `mac` TXT while it's awake, persists it on the saved-host record, and — when reconnecting to an offline host — sends a magic packet before connecting, plus an explicit "Wake host" action. Apple wraps the C-ABI; linux/windows call the core fn directly (linux also gains a --wake CLI mode); android via a new nativeWakeOnLan JNI export (the mDNS browse record gains a 7th mac field); decky shells out to the linux client's --wake before launching the stream.

iOS/tvOS need the managed com.apple.developer.networking.multicast entitlement (pending Apple approval), so the wake path + UI are gated off via PunktfunkConnection.wakeOnLANAvailable and the entitlement is commented out — keeping iOS/tvOS releasable. MAC-learning stays active on every platform so it lights up the moment it's ungated. macOS works today.

enricobuehler 3bf14a3df7 feat(core,host): Wake-on-LAN sender + host MAC advertisement
Add a runtime-free Wake-on-LAN sender in punktfunk-core (per-interface subnet-directed broadcast + 255.255.255.255 on ports 9/7, repeated, optional last-known-IP unicast) exposed both as a Rust fn and a punktfunk_wake_on_lan C-ABI (ABI v3), plus a parse_mac helper. The host enumerates its wake-capable NIC MAC(s) and advertises them in a new mDNS `mac` TXT record (routed NIC first), and best-effort detects & warns (never modifies) when the NIC isn't armed for WoL.

MAC delivery is via the unauthenticated mDNS TXT rather than the connection handshake by design: a spoofed MAC only makes a wake fail (the packet is inert; the cert fingerprint still gates the connection), and it avoids threading through the hot connect path.

enricobuehler bcf972e341 fix(apple/gamepad): deliver PS/Home + Share buttons on macOS
macOS reserves the controller Home/PS and Share/Create buttons for its own system gestures and never delivers them to the app unless it declares the Game Controllers capability. Add GCSupportsControllerUserInteraction=YES to the macOS target only (iOS/tvOS rely on the focus engine, so it must not be in the shared plist), alongside the existing preferredSystemGestureState=.disabled.

enricobuehler 17a157761d docs(security): record measured WDA_EXCLUDEFROMCAPTURE behavior + capture-vs-viewer framing
Tested on .173: a WDA_EXCLUDEFROMCAPTURE window (affinity readback 0x11,
confirmed active) is pixel-identically visible in the punktfunk/1 stream
across no-flag / flag-set / flag-cleared phases — the flag makes no
difference to a present-tap capture. Replace the "untested, treat as
expected" note in the IDD-push residual list with the measured result,
and correct the framing: WDA visibility matches what a person at the
screen sees (it exceeds an ordinary capture tool, not the physical
viewer).

Add the matching public-facing paragraph to the security page covering
both asymmetries — WDA windows appear (same as a physical viewer), DRM
video is blanked (less than a physical viewer) — tied back to the page's
"a client sees what someone at the machine sees" model.

enricobuehler 24d53b7584 fix(host): don't count punktfunk's own virtual Deck as a physical Steam controller
The Steam-conflict gate scanned /sys/bus/hid/devices for non-virtual 28DE
devices, but the usbip/gadget virtual Decks present a REAL USB device (vhci
resolves through vhci_hcd, not /devices/virtual/) — so a just-ended session's
pad still detaching, or a concurrent session's live one, read as "physical
Steam controller attached" and degraded every back-to-back Deck session to
DualSense (observed live on Bazzite). Exclude our pads by their PFDK… serial
(HID_UNIQ), with the vhci_hcd path as belt and braces.

enricobuehler db63647337 fix(client-linux): Deck trackpad clicks — bind to the correct pad, stop riding the button plane
SDL's Steam Deck mapping delivers the pad clicks as gamepad BUTTONS with no
surface identity: the generic `touchpad` button is the LEFT pad's click and
`misc2` the RIGHT's (SDL_gamepad_db.h `touchpad:b17,misc2:b16`). The client
forwarded `touchpad` as wire BTN_TOUCHPAD — which the host maps to the RIGHT
pad click (DualSense convention) — and dropped `misc2` entirely: a left-pad
click registered on the right pad, a right-pad click nowhere, and the
mis-routed state could stick.

Clicks from a multi-touchpad pad now ride the rich plane as TouchpadEx with
their surface, reusing the surface's live contact point (click buttons carry
no position). forward_touch carries the held click through motion frames so a
touch update can't clear a click mid-press, and the flush lifts held clicks on
detach/pad-switch. A DualSense's single touchpad button stays on the button
plane unchanged.

enricobuehler f2cf65ef33 fix(client-linux): Deck raw-pad capture — clear Steam's SDL device filter, honest degradation warning
The Deck's built-in controller can never leave Steam Input ("Steam Controller"
is always-required in the shortcut's matrix; Disable Steam Input only affects
other controller brands), so the raw 28DE:1205 device is the only path to the
trackpads/paddles/gyro. Steam hides it from SDL by launching shortcuts with
SDL_GAMECONTROLLER_IGNORE_DEVICES naming every physical pad it virtualized —
clear it (and _EXCEPT) at startup while single-threaded, logging what Steam set
as field evidence. The post-attach warning now states the real condition (raw
pad never enumerated; sticks + buttons still work) instead of advising a
Steam Input toggle that doesn't exist for the built-in controller.

enricobuehler 959ec30003 fix(client-linux,host): Deck video defaults to software decode + input-interception diagnostics
Video (Deck): the VAAPI zero-copy path renders corrupt/gray/washed-out on the
Deck — root-caused to Mesa >= 25.1 exporting radeonsi VCN decode surfaces TILED
(the Flatpak runtime's Mesa 26 drives both the decoder and GTK's GL, and GTK's
tiled-NV12 dmabuf import mishandles it; desktop Tier-1 validations ran distro
Mesa with linear export). `auto` now resolves to software on a Deck (clean,
correct-colour, easily handles 1280x800 HEVC); PUNKTFUNK_DECODER=vaapi still
forces the hw path, with the descriptor modifier dump + GSK_RENDERER as the
bisect levers. Also reserve extra_hw_frames=4 on the VAAPI decoder: the
presenter pins mapped surfaces past receive_frame, and the fixed pool recycling
a surface the renderer still samples is intermittent block corruption anywhere.

Input (Deck): with Steam Input ON for Punktfunk, SDL sees only Steam's virtual
X360 pad — the right trackpad arrives as a plain right stick and the left
trackpad/paddles/gyro not at all, silently. The client now checks once the
post-attach enumeration settles and raises a toast + warn naming the fix
(disable Steam Input for the shortcut). The host logs a one-shot warning when
InputPlumber is running (Bazzite default) since it can grab the virtual Deck
pad and re-emit it under a different identity.

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

that + --socket=pulseaudio.

enricobuehler d1af6304c7 fix(flatpak): expose native PipeWire socket so client audio works
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.

enricobuehler 2f7dae2404 docs(bazzite): fix the "rpm-ostree upgrade doesn't update punktfunk" trap
`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.

enricobuehler 7eea9836b8 fix(clients): GTK + Decky polish batch from live Deck/Windows testing
GTK Linux client:
- hosts/library: clicking a card was dead — the handler was on
  FlowBoxChild::activate (never emitted on click); bridge child-activated
  → child.activate() on the FlowBox (ui_hosts, ui_library).
- stream: the Ctrl+Alt+Shift+D/Q/S chords (and all key forwarding) were
  dropped because the key controller sat on the overlay, which loses focus
  to the header back button after nav.push+fullscreen — move it to the
  window and remove it on teardown.
- video: a mid-session VAAPI decode error rebuilt a software decoder but
  never requested a keyframe, so under the infinite GOP the picture stayed
  gray/frozen forever. Request an IDR on any VAAPI error, keep the hardware
  decoder, and demote to software only after repeated failures.
- stream: fix a per-session Capture↔overlay reference cycle that leaked the
  overlay subtree + the Arc<NativeClient> on every session end — hold the
  overlay weakly.
- stream: accumulate the fractional wheel remainder so precision-scroll
  (Deck trackpad / hi-res wheels) sub-unit deltas aren't dropped.
- gamepad library: keep the launcher smooth on the Deck — freeze the aurora
  and trim the visible card range (fewer 3D offscreen passes) on low-power.
- gamepad: log full pad identity (vid:pid:name:type:virtual) on attach to
  diagnose an empty controller list on the Deck.
- cli: --connect host:<badport> silently did nothing; default to 9777 + warn.
- css: add the missing .pf-neutral pill rule; fix the clipped most-recent
  accent (inset outline instead of a corner-clipped box-shadow bar).

Decky plugin:
- surface the on-screen library browser: label the host-row Games button.
- fix silent pin data-loss — the detached Games modal captured a frozen
  pins array, so pinning a second game clobbered the first; mirror pins in
  a ref and track the modal's pinned ids locally for a live label.
- route pair-required hosts through the pairing modal from the fullscreen
  Stream button (parity with the QAM panel).

enricobuehler 5610f4f210 fix(flatpak): keep both channels in the OSTree summary (fixes stable "No such ref")
The surfaced install command
  flatpak install --user https://flatpak.unom.io/io.unom.Punktfunk.flatpakref
failed with "No such ref 'app/io.unom.Punktfunk/x86_64/stable'". The stable
commit's objects are on the server, but the repo *summary* (what flatpak reads
to resolve refs) listed only canary.

Root cause: each CI run builds a fresh SINGLE-branch local OSTree repo,
build-update-repo regenerates the summary from that one branch, and rsync
uploads it without --delete. Objects for both channels accumulate, but the
summary is overwritten every run and only names that run's branch. Canary runs
on every main push, stable only on tags — so a tag published stable, then the
next canary push clobbered the summary back to canary-only.

Fix: seed the local repo from the live server (rsync repo/ DOWN) before the
build, so it carries every published branch; the build only adds this run's
commit and the regenerated+signed summary keeps both channels. Single shared
repo kept (no URL/Caddyfile change; existing installs fixed transparently).
Adds a refs log after build-update-repo as a clobber tripwire. Also adopts
scripts/ci/pf-version.sh for the canary base (see previous commit).

enricobuehler e459109818 ci(release): derive canary version from git tags (single source of truth)
Every release workflow hardcoded a canary base version (0.5.0 in
Apple/Android/rpm/flatpak/deb, 0.3 in windows-msix/windows-host/decky) that
had to be hand-bumped on each stable release and wasn't. With stable at
v0.6.0, every canary was a version *behind* stable — e.g. the Apple canary
showed up on TestFlight as 0.5.0 while 0.6.0 was already published.

Add scripts/ci/pf-version.{sh,ps1} (bash + pwsh twin) as the single source of
truth: stable = the vX.Y.Z tag; canary = latest stable tag with minor+1,
patch 0 (v0.6.0 -> 0.7.0), so canary is always exactly one minor ahead of the
newest release with zero maintenance. Falls back to the workspace Cargo.toml
version when no tag is fetchable. All workflows now eval/call it and format
their own channel suffix off $PF_BASE; only the canary branch changed, stable
branches and per-channel suffixes are untouched. channels.md drops the old
manual "bump the canary base" release step.

enricobuehler e56470cf56 fix(apple-client/audio): capture the right channel of a multi-channel mic + diagnostics
The mic uplink handed the host pure digital silence on a multi-channel
interface: AVAudioConverter's N→stereo downmix takes channels 0/1, but a
pro interface puts the mic on ONE higher discrete channel. Fold the input
to a mono bus ourselves instead — pick the mic's channel (or sum all) and
resample that to the encoder's 48 kHz stereo, so the silent 0/1 downmix
never happens.

- New "Microphone channel" setting (macOS): Auto (sum every channel — a
  lone hot mic passes at full level) or pin 1-based channel N. Picker
  appears only for multi-channel devices, driven by the device's input
  channel count.
- Diagnostics that make this class of failure self-naming next session:
  log the actual live capture device + format + fold mode, warn on a
  silent UID fallback, and a one-shot silence tripwire on the EXTRACTED
  signal (WARN on 10 s of zeros, else peak dBFS).
- foldToMono extracted as a pure, unit-tested helper (pin / sum-clamp x
  interleaved / deinterleaved / mono / out-of-range).

enricobuehler 477adeaad8 feat(probe): --mic-burst — real-client mic pacing for jitter-buffer regression tests
The steady 5 ms mic-test cadence never trips host-side buffering bugs:
the WASAPI crackle (fixed in the previous commit) only reproduced under
a real client's bursty input tap. --mic-burst paces the tone the same
way (two 20 ms Opus packets every 40 ms), so recording the host mic and
counting silence gaps regression-tests the jitter buffer headlessly.
Validated against the fixed Windows host on the lab box: 15 s of bursty
tone, zero mid-stream gaps >=3 ms (gaps confined to the first 40 ms
priming window).

enricobuehler 547bc250b6 fix(host/audio): WASAPI virtual mic — port the priming jitter buffer (crackling fix)
Mac → Windows mic passthrough crackled heavily while the identical
stream was clean on the Linux host. Cause: clients push mic audio in
BURSTS on their own clock (the Mac input tap yields ~two 20 ms Opus
packets every ~42 ms) while the WASAPI render loop pulled a block every
~10 ms device period and greedily drained whatever was queued, padding
the rest with zeros — the queue sat near-empty and most periods
inserted mid-stream silence. The Linux backend has absorbed this since
day one with its priming jitter buffer; the WASAPI loop had none.

Port the same semantics: emit silence until ~48 ms is buffered (covers
the worst inter-burst gap), then play from the cushion (zero-filling
only a momentary shortfall), re-prime only after a genuine full drain
(client went quiet). Queue cap raised 80 → 120 ms for burst headroom;
steady-state added latency ≈ the 48 ms cushion.

Diagnosed live on .173: probe tone recording from CABLE Output proved
the endpoint wiring, then the burst-vs-period math explained the
crackle. Build-verified on Windows; on-glass listen pending.
