Modifier keys arrive only as flagsChanged, and the direction was recovered
by diffing the device-dependent L/R bits (NX_DEVICE*KEYMASK) alone. Those
bits are undocumented and some keyboards omit them (only the class bit,
e.g. NX_CONTROLMASK, is set), so the diff saw no transition and the key
never reached the host — no Ctrl shortcuts. SDL/Moonlight key off the
event's keyCode for exactly this reason; do the same: keyCode names the
changed key, the class bit says up, the device bits (when present) pick
the side, and a tracked-held-state flip covers keyboards without them.
PUNKTFUNK_INPUT_DEBUG=1 now also logs every flagsChanged (keyCode + raw
flags) so a field report is diagnosable from client logs.

Direct-SDK AMF encoder (encode/windows/amf.rs), the AMD analogue of the
direct-NVENC path, replacing the libavcodec *_amf dispatch. C-vtable FFI
pinned to AMF headers v1.4.36, runtime-loaded from the driver's amfrt64.dll
(no build feature, no new dependency) exactly as NVENC loads its DLL.
- AVC/HEVC (SDR NV12 + 10-bit HDR P010) and AV1 (RDNA3+, probed); a bounded
poll retires the libavcodec ~2-frame output hold; native in-place reset().
- Intra-refresh wave (PUNKTFUNK_INTRA_REFRESH), in-band HDR mastering/CLL
metadata (*InHDRMetadata -> HEVC SEI / AV1 OBU), and a native codec probe
feeding the GameStream advertisement (windows_backend_is_ffmpeg ->
windows_backend_is_probed).
- AMD dispatch / advertisement / 4:4:4 are native-only; the libavcodec AMF
fallback and the PUNKTFUNK_AMF_FFMPEG hatch are removed. FFmpeg serves QSV
only (its AMF path retained solely as the latency A/B comparator).
- Overload back-pressure: submit bounds in-flight surfaces below the input
ring, draining finished AUs (buffered for poll, FIFO-preserved) to free a
slot and retry on AMF_INPUT_FULL instead of tearing the encoder down and
forcing an IDR; this also closes a latent ring-overwrite corruption seen
under load on-glass.
Validated on the lab Ryzen iGPU (AMF runtime 1.4.37): HEVC/AVC across a
native reset, HEVC Main10 mastering+CLL SEIs byte-verified, intra-refresh
accepted, a backpressure burst FIFO-clean, and end-to-end via the macOS
client. Measured §5.2 latency A/B: native encode_us p50 ~5 ms (0.31 frame
periods) vs libavcodec ~17 ms (1.01). 4:4:4 stays unsupported (VCN hardware
limit). Live-gated tests skip cleanly on non-AMD boxes.

Like the Linux client, the Windows client had WOL send + MAC storage + a Wake
action + fire-and-forget auto-wake, but no poll-until-up + IP re-key. Add the
polished flow (mirrors Apple HostWaker + the request_access screen pattern):
- connect::wake_and_connect — send the magic packet, show a cancelable
Screen::Waking busy page, poll discovery::browse() until the host reappears
(re-sending every 6 s, 90 s budget), then dial; re-key the saved host
(KnownHosts::upsert) if it woke on a new IP.
- Screen::Waking + waking_page, routed in app/mod.rs (mirrors RequestAccess).
- the saved-host tile routes an offline-with-MAC tap to wake_and_connect;
MENU_WAKE stays a pure send-only button.
Reviewed against the request_access reference — DiscoveredHost/KnownHost/Target
types, the widgets, .call()/.lock(), and the initiate signature all match;
compile-verified by Windows CI (no local Windows toolchain).

The Linux client already had WOL send + MAC storage + a Wake action + auto-wake-
on-connect, but the auto-wake just fired a packet and did one dial to the stored
address — so a host that woke on a new DHCP lease failed, and there was no
"waiting" feedback. Add the polished flow (mirrors Apple/Android HostWaker):
- ui_trust::wake_and_connect — send the magic packet, poll mDNS until the host
reappears (re-sending every 6 s, 90 s budget) behind a cancelable "Waking…"
dialog, then connect; if it woke on a new IP, re-key the saved host first.
- trust::rekey_addr — no-churn addr/port update keyed by fingerprint.
- the hosts page routes an offline saved-host-with-MAC tap to on_wake_connect
(the new flow) instead of fire-and-forget wake + immediate dial.
Builds + clippy + fmt clean.

The core's deliberate-quit close (NativeClient::disconnect_quit → QUIT_CLOSE_CODE,
host skips the keep-alive linger) was implemented but never called by any client.
Wire it to each client's explicit user-disconnect action — NOT to a network drop /
host-ended / app-background (those keep the linger for a reconnect):
- core: new C-ABI punktfunk_connection_disconnect_quit(c) for the ABI clients
- Linux (direct-core): Ctrl+Alt+Shift+D + the controller escape chord
- Windows (direct-core): Ctrl+Alt+Shift+D
- Apple (C-ABI): PunktfunkConnection.disconnectQuit() + a `deliberate` flag on
SessionModel.disconnect() (sessionEnded passes false → keeps the linger)
- Android (JNI): new nativeDisconnectQuit export, called from the back gesture +
the Select+Start+L1+R1 chord (not the host-gone watchdog)
- probe already did this via --quit (77871d6)
Verified: core + Linux client + Android (cargo-ndk + gradle) build clean;
Windows/Apple compile-checked by CI.

`cargo fmt --all --check` (a CI gate) failed on main: config.rs (the new

The library browser was browse-only — the A button (and a tap) did nothing.
Wire it to connect + boot straight into the selected title: thread a `launch`
id (the store-qualified library id `steam:<appid>` / `custom:<id>`) through
nativeConnect → NativeClient's Hello.launch (was hardcoded None), add a shared
connectToHost() the ConnectScreen and the library launcher both use, and have
LibraryScreen dial the host with launch=game.id on A / tap — with a launching

app+kit Kotlin compiles (gradle, 3 ABIs).

On-glass A/B on the Ryzen 7000 iGPU (1080p120 HDR P010, hevc_amf,
PUNKTFUNK_PERF stage split): the system-memory readback costs the encode
thread 2.7-2.9 ms p50 (6.6 ms p99) per frame in submit; the zero-copy D3D11
pool path does the same work in 0.26 ms p50 (0.5 ms p99) — and on an iGPU the
readback also burns the shared memory bandwidth the game needs. The docs-site
already promised "on by default ... D3D11 on Windows" since the Linux flip
(9814368 was Linux-only); the Windows code now delivers it.
PUNKTFUNK_ZEROCOPY becomes a tri-state override: unset defers to a per-vendor
default in zerocopy_enabled(vendor) — ON for AMF (validated above; open
failures still fall back to system-memory readback), OFF for QSV until it is
validated on Intel glass (the fallback only catches *setup* errors; a QSV
derive that opens but maps wrong would corrupt silently, so probe-never-assume
applies). Explicit values force either way: 0|false|off|no = readback,
anything else = zero-copy, so the old presence-style =1 keeps working.

Field reports: Windows AMD/Intel streams freeze after ~3-5 min regardless of
desktop activity. Root cause: the libavcodec AMF/QSV poll is non-blocking
(EAGAIN -> Ok(None)), and the encode loop's drain treated None as benign
without popping `inflight` — a wedged driver (QueryOutput stops producing)
meant frames kept being submitted, inflight grew unboundedly, no AU ever
reached the send thread, and nothing logged: a silent permanent freeze. The
input-side twin: once libavcodec's one-frame buffer fills, avcodec_send_frame
EAGAINs and the submit `?` killed the whole session.
Add `Encoder::reset()` (in-place encoder rebuild; implemented for AMF/QSV by
dropping the wedged libavcodec encoder so the next submit re-opens it on the
current device, forced IDR) and an encode-stall watchdog in the stream loop:
trip on a poll error, on no AU within max(2 s, 8 frame intervals) while frames
are owed, or on an owed backlog worth more than the window's frames (the
slow-leak latency-runaway form). Recovery is a bounded (5 consecutive, cleared
by any delivered AU) in-place rebuild + forced IDR — a logged ~one-second
hiccup instead of a dead stream; exhaustion or a reset-less backend still
fails the session with a clear error. Submit failures route through the same
bounded recovery. The three existing pipeline-rebuild paths (session switch,
mode switch, capture loss) now also clear the stale in-flight records that
pointed at the dropped encoder.
Backends whose poll blocks (direct NVENC sync, software) can't false-trip:
they never return Ok(None) mid-stream and drain inflight below depth each
tick. Validated: clippy -D warnings (nvenc,amf-qsv), 191 host tests, synthetic
E2E 300/300 frames, and an on-glass AMD iGPU session (1080p120 HDR hevc_amf).

cur_node_id (the capture 5-tuple's node id, added for the Linux dedicated-
game-exit check) is read only under #[cfg(target_os = "linux")], so on the
Windows nvenc/amf-qsv build it was assigned but never read — failing
`clippy -D warnings`. Read it on non-Linux platforms (the `let _ = &launch`
idiom already used in this file).

Release 0.8.1: game-mode + dedicated game sessions, zero-copy GPU import
process-isolation (and zero-copy on by default on all backends), user-defined
custom display presets, and a physical-monitor refresh-preservation fix.

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).

Connecting reset an existing physical monitor's refresh (e.g. 120->60 Hz)
because the topology code read the physical's mode AFTER the virtual output
perturbed the compositor layout — by which point it had already been
downgraded. Read/preserve each physical's mode from a pre-connect snapshot.
- Mutter: build_primary_keeping_physicals takes the pre-virtual snapshot and
preserves each physical's real mode (pick_keep_mode, unit-tested)
- KWin: capture each output's mode when disabling for exclusive, re-assert it
on re-enable (a bare enable defaulted to ~60 Hz)
- Windows: skip the refresh-resetting SDC_TOPOLOGY_EXTEND when a physical is
already active

Save named bundles of the display-management policy (the six behavior axes
plus the game-session axis) as custom presets, alongside the built-ins. A
custom preset is data — stored in <config>/display-presets.json — not a Preset
enum variant, so DisplayPolicy::effective() stays pure and the built-in set is
untouched; applying one writes a Custom policy via the existing PUT
/display/settings.
- policy.rs: CustomPreset/CustomPresetInput + load/add/update/delete store
- mgmt.rs: GET/POST /display/presets + PUT/DELETE /display/presets/{id},

The tiled EGL/GL→CUDA import crashed the whole host (SIGSEGV inside
libnvidia-eglcore via cuGraphicsMapResources) when the compositor
invalidated an imported dmabuf mid-map — reproduced on the Bazzite F44
Game→Desktop switch (design/zerocopy-hardening-handoff.md). A driver
SIGSEGV is uncatchable in-process, so the whole EglImporter (tiled
EGL/GL→CUDA and LINEAR Vulkan→CUDA) now runs in a per-capture
`zerocopy-worker` subprocess: dmabuf fds go over a SEQPACKET socketpair
(SCM_RIGHTS, sent once per buffer keyed by dmabuf st_ino; NeedFd resend
self-heals cache desync), frames come back as CUDA-IPC pooled device
buffers (still zero-copy, +one socket RTT/frame). Worker death poisons
the capturer so the existing capture-loss rebuild runs — the host
survives; 3 consecutive deaths latch the GPU import off (CPU/SHM path).
PUNKTFUNK_ZEROCOPY_INPROC=1 keeps the old in-process import for
debugging/A-B.
Also fixed along the way: a failed *tiled* import no longer falls
through to the CPU mmap de-pad (which scrambled tiled bytes; LINEAR
keeps the fallback); Nv12Blit dropped its GL textures while still
CUDA-registered (unregister now runs first); GlBlit had no Drop at all
(GL objects leaked per size change); VkBridge's per-fd src cache is now
invalidated on renegotiation/eviction instead of never.
Design: design/zerocopy-worker-isolation.md. Unit tests: 14 new
(protocol fd-passing, worker dispatch, client handshake/death/NeedFd,
death latch). On-glass validated on the RTX 5070 Ti/GNOME box (.21):
the worker path streams at p50 1.30 ms (NV12, 1800 frames 0-mismatched,
parity with the in-process path), and a kill -9 of the worker
mid-stream is survived by the host and recovered — poison -> capture
lost, rebuilding pipeline in place -> a fresh worker in ~185 ms ->
streaming resumes (2385 frames, 0 mismatched). A real KWin
compositor-crash repro is still pending (a worker kill -9 is strictly
harsher, so it corroborates).

- Pin android-actions/setup-android, appleboy/scp-action, and
appleboy/ssh-action to commit SHAs (version kept in a trailing comment).
These run in jobs holding the Android signing keystore, Play

- Add a bun-audit job to audit.yml over web/bun.lock — the console holds
the login gate, session sealing, and mgmt token, so its deps matter too

Remediates the two web-console residuals from the 2026-07-05 posture audit:
- Brute-force throttle (loginThrottle.ts): per-IP exponential backoff
after 5 free attempts, plus a global floor for spread-out floods, keyed
on the socket peer IP (not spoofable X-Forwarded-For) with a size-capped
map. The constant-time compare already stopped the timing leak; this
bounds guess *volume* against a by-design LAN-exposed console.
- Session seal key now derives from the high-entropy mgmt token instead of
the low-entropy login password, so a captured cookie is no longer an
offline password oracle. Falls back to the password only when no token
is configured (dev/local). Rotating the token now invalidates sessions.
- Replace the process-wide NODE_TLS_REJECT_UNAUTHORIZED=0 with per-request
Bun TLS scoped to the loopback proxy hop; a non-loopback mgmt URL now
verifies normally. Dropped the env var from the systemd unit, Steam Deck
installer, Windows run scripts, env examples, and web README.

Close the latency gap on the Android client with per-SoC decoder tuning, an
event-driven decode loop, and full system integration.
- Decoder selection: rank MediaCodecList decoders in Kotlin (hardware/vendor
preferred, software avoided, FEATURE_LowLatency probed) and create the chosen
one by name. Per-SoC low-latency keys gated on the codec-name prefix: Qualcomm
picture-order + low-latency, Exynos (also Google Tensor), Amlogic, HiSilicon;
MediaTek vdec-lowlatency set unconditionally. operating-rate = MAX (Qualcomm)
vs priority = 0 (else) are mutually exclusive. NVIDIA/Rockchip/Realtek have no
vendor key — covered by ranking + the standard low-latency key.
- Async decode loop: AMediaCodec async-notify replaces the poll loop, presenting a
decoded frame the instant it is ready instead of waiting out a poll interval.
Behind USE_ASYNC_DECODE with the synchronous loop kept for A/B during bring-up.
- System integration: Wi-Fi FULL_LOW_LATENCY lock and HDMI ALLM
(setPreferMinimalPostProcessing) for the stream's lifetime; game_mode_config.xml
opting out of OEM downscaling / FPS overrides.
- Pipeline: boost the data-plane pump + audio thread priorities, AAudio usage=Game,
DSCP marking on by default on Android, ADPF setPreferPowerEfficiency(false),
and setFrameRateWithChangeStrategy(ALWAYS) to force the HDMI mode switch on TV.
- lowLatencyMode master toggle (default on) as the escape hatch; the stats HUD now
shows the resolved decoder name.

Split the docs' single distro×desktop axis (ubuntu-gnome / ubuntu-kde / fedora-kde) into two,
which deduplicates the shared mechanics and scales to distros that run several desktops (Arch):
- Install the host — per distro/OS (ubuntu, fedora, arch, bazzite, steamos-host, windows-host):
GPU driver + package + input group, then a canonical "Configure your desktop" funnel.
- Configure your desktop — per compositor (kde, gnome, gamescope, sway): host.env, compositor
quirks, the headless session, and starting the host.
New shared web-console page (enable · login password · arm pairing) removes the console/password
block that was copy-pasted across all seven host pages. Merged ubuntu-gnome + ubuntu-kde into
ubuntu; renamed fedora-kde to fedora; kept bazzite and steamos-host as dedicated appliance guides
(trimmed of duplication). Moved the KWin headless session, the GNOME EGL/lock traps, and the
gamescope attach/managed model out of the distro pages onto their compositor pages.
Fixed while restructuring: distro-specific paths on kde (kde-desktop-setup.sh is Fedora/Bazzite-only;
the .deb ships host.env.kde under /usr/share/punktfunk-host), the interactive "start the host" step
that was lost in the merge, sway over-claiming Hyprland, and a pre-existing broken anchor in
how-it-works.
Removal of the three old pages was captured by the preceding commit b28ddfc (a concurrent commit
swept up the staged git-rm); the net docs tree is correct. Fumadocs build + internal link/anchor
check green.

Console polish on the Virtual displays card + shell:
- Topology help now leads with the streamed display's role (Extend/Primary/Exclusive) instead of
the confusing physical-monitor-only framing; notes the headless case. Identity help spells out the
actual behavior (stable per-client identity → the desktop reapplies that client's scaling/resolution
on reconnect) + what Shared / Per-client / Per-client+resolution each do.
- Cap description/help width at max-w-prose so long help text isn't a full-viewport line on large screens.
- Mobile bottom nav: 8 flat tabs were too cramped → 4 pinned tabs + a "More" tab whose sheet holds the
rest (Performance/Logs/Pairing/Settings), "More" highlighted when the active route is in the overflow.
- More breathing room under the "Preset" heading.
web tsc + biome + vite build green.

rust-toolchain.toml pinned the floating "stable" channel, so the CI image baked whatever
stable existed at image-build time. When the image is rebuilt onto a newer stable,
rustfmt's rules shift and `cargo fmt --all --check` fails on files nobody touched — the
recurring format-drift that keeps red-lighting CI.
Pin channel = "1.96.0" (== today's stable: rustc ac68faa20, rustfmt 1.9.0-stable), the
exact build CI already runs, so this is a no-op now but locks formatting for good: local
dev, the Linux CI image, and the Windows runner all use rustup and honor this file, so
they converge on one rustfmt. Formatting now only changes in a deliberate bump-this-pin-
and-reformat commit. ci.yml cache comment updated to match.

The >60 Hz virtual-monitor path (RecordVirtual "modes" with the client's exact WxH@Hz)
was gated behind PUNKTFUNK_MUTTER_VIRTUAL_REFRESH, default OFF, after a high-refresh
virtual CRTC SIGSEGV'd gnome-shell on session teardown. That crash was since fixed by
stopping the screencast before any monitor reconfig, so the gate is dead weight — and a
silent footgun: every non-headless GNOME client was capped at Mutter's PipeWire-derived
60 Hz unless they knew the hidden flag.
Make it the default: the custom-mode path now runs whenever mode.refresh_hz > 60 (≤60 Hz
stays byte-identical to before — Mutter's 60 Hz default is already correct), and the
virtual_refresh_enabled() env read is removed. Docs updated (configuration.md env table,
vrr-plan.md reference).

when false) for clippy::unnecessary_lazy_evaluations.

The reconnect-preempt (e8531a9, preempt_same_identity) reads the process-global admission table
and signals same-identity live sessions. The three in-process-host tests each bind a fixed loopback
port and share that ONE table, so running them concurrently let one test's connection preempt +
close another's live session — an intermittent `next_au: Closed` in c_abi_connection_roundtrip
(surfaced under full-workspace load; a lucky pass hid it at e8531a9). Serialize them on a
poison-tolerant lock. Test-isolation only — in production a host is one process with unique client
certs, so same-identity preempt is correct. Full workspace `cargo test` now green (18 suites, 3× clean).

Bring the Android client to parity with Apple's gamepad experience and finish
Wake-on-LAN.
- Console/gamepad home: host carousel, aurora chrome, mTLS game-library coverflow,
and an input-aware legend that switches between gamepad face buttons and a
TV-remote select-ring + arrows based on the last-used input.
- Wake-on-LAN: the fire-and-forget send is upgraded to wait-until-up
(WakeController/WakeOverlay: resend + mDNS poll, 90s timeout, cancel/retry,
fingerprint-matched so a host that cold-boots onto a new DHCP IP still connects),
plus host edit (touch dialog + console form) with an auto-filled MAC.
- Android TV: brand banner (android:banner), density-aware console scaling, D-pad/
remote nav (Up = Settings, Down or the pad Select button = host Options),
emergency stream-exit chord, and 120Hz console refresh.
- Touch UI: settings split into subpages with a tablet NavigationRail, axis-aware
tab animation (horizontal on phones, vertical on the tablet rail), animated
settings navigation, and a licenses screen with a back button + the real
workspace version (read from Cargo.toml).
- Vector Lock/controller icons (no emoji); bundled Geist font.

Stage 8 polish. `GET /api/v1/local/summary` (the tray's loopback-only unauthenticated status
source) gains `kept_displays` — the count of lingering/pinned virtual displays (held with no live
session), over the already-validated `registry::snapshot()`. The tray shows it in the idle tooltip
("idle · 1 display kept"), so a user knows a display — and, under exclusive topology, their physical
monitors — is being held (e.g. a gaming-rig `forever` pin). Release stays via the console: a
state-changing release can't be an unauthenticated endpoint, and the non-elevated Windows tray
can't read the SYSTEM-DACL'd mgmt token, so a tray release button isn't cleanly cross-platform.
`#[serde(default)]` on the tray side keeps it compatible with an older host. Tray tests green.

Bring the user-facing + project docs in line with the shipped, on-glass-validated state (Stages
0-5 §6A + keep-alive hardening + gaming-rig) ahead of a merge decision:
- docs-site/virtual-displays.md: drop the now-false "stored but not yet enforced / following

multi-monitor layout are all live; gaming-rig/forever ships (freed via Release); document the
reconnect-always-resumes + deliberate-quit-skips-linger behavior and the PUNKTFUNK_IDLE_TIMEOUT_MS
knob. KDE persistent scaling → ✅ today (validated); Windows primary → shipped; Sway exclusive
stays "following release".
- README: a "displays you configure, not just create" differentiator bullet.
- CLAUDE.md: the display-management invariant now reflects Stages 0-5 shipped (all axes enforced,
forever/Pinned, hardened reconnect) instead of "Stage 0 shipped".

`let (mut paths, mut modes)` — `modes` is only read (`modes.as_slice()`), never mutated. A
pre-existing unused_mut (from 8fa4757) that the Linux CI never caught because win_display.rs is
#[cfg(windows)]; surfaced by a manual .173 build. Would fail the release-gated Windows clippy.

Completes the last §6A-era preset. The Linux registry already resolved forever→Pinned (pure
lifecycle machine); the blockers were the Windows manager, the mgmt reject, and the console tag:
- Windows manager: new `MgrState::Pinned { mon }` — the last-released monitor under keep_alive=forever
is kept indefinitely (like Lingering but the linger timer never fires). A reconnect preempts +
recreates it (same as Lingering — a reused IddCx swap-chain is dead), snapshot reports "pinned",
and `force_release` (POST /display/release, the §8 escape hatch) frees a pinned monitor. release()
branches on the new `keep_alive_forever()`; all MgrState matches made exhaustive over Pinned.
- mgmt PUT /display/settings: stop rejecting keep_alive=forever (now honored on both platforms with a
release path). OpenAPI regenerated.
- web: un-disable the gaming-rig preset (DISABLED_PRESETS now empty) — one-click applies.
Linux paths + web/tsc/openapi green; 47 vdisplay tests pass. The Windows manager.rs is #[cfg(windows)]
(not compilable on the Linux dev box) — build-verified + on-glass validation on .173 to follow.

Two probe test-infra fixes needed to validate the keep-alive hardening (e8531a9) on glass:
- `--seconds N` caps the receive loop (was a hardcoded 120s), so a probe against a live `serve`
host ends its session promptly and reaches the graceful `conn.close`.
- After `conn.close`, wait for the endpoint to flush the CONNECTION_CLOSE frame (bounded 2s)
before exiting — otherwise the process drops the endpoint before quinn sends the close, and the
host waits out the idle timeout instead of seeing the close CODE (which the `--quit` deliberate-
quit path and normal code-0 close both depend on).

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.

On-glass testing (Test 2, KWin .116) surfaced that a reconnect within the QUIC idle-timeout
window (~8s) lands on a fresh SECOND display instead of reusing the kept one: the old session
was still Active (not yet Lingering), so the registry's keep-alive reuse (which only matches
Lingering) skipped it and the old session kept streaming to nobody. Three fixes:
#3 Same-client reconnect preempt (the real fix): admission::preempt_same_identity() lists a
reconnecting client's OWN still-live session(s) (same cert fingerprint); serve_session signals
their stop + waits the release grace BEFORE acquiring, so the zombie tears down → its display
lingers → the reconnect REUSES it instead of making a second. Implements the "preempts
downstream" the admission docs already promised. Independent of the mode_conflict policy; the
pure core (same_identity_stops) is unit-tested.
#2 Deliberate quit skips linger: a client that deliberately disconnects closes the QUIC connection
with QUIT_CLOSE_CODE (0x51, shared in core::quic); the host reads the ApplicationClosed reason
and tears the display down immediately (registry release() gained force_immediate →
Linger::Immediate; multi-session-safe via the pure lifecycle machine), while a bare disconnect
still lingers for reconnect. Threaded via a session quit flag → the DisplayLease.
NativeClient::disconnect_quit() + punktfunk-probe --quit drive it; GameStream (Quit App /
h_cancel) is a documented follow-up.
#1 Configurable disconnect-detection latency: the QUIC control-connection idle timeout
(stream_transport, 8s default) is host-tunable via --idle-timeout-ms / PUNKTFUNK_IDLE_TIMEOUT_MS,
clamped >=1s with a keep-alive that scales to it so a live session never false-closes. Default
unchanged (8s stays load-bearing for the Windows IDD-push reconnect flow).
Workspace check + 63 core / 215 host / 47 vdisplay tests green; clippy clean.

The preset options were raw <button>s — flat, no motion/material — unlike the rest of
the console. They now render as the `interactive` AnimatedCard (motion hover + specular
material, consistent with every other card), keyboard-accessible (role=button + Enter/
Space), with a 2px primary ring for the active one and a proper disabled state for
gaming-rig.

- Every option in the custom form now renders through one `Field` wrapper (label →
control → help at a consistent `space-y-3`), so the label→input gap is roomier and
identical across keep-alive, the button groups, and max-displays — the first field no
longer spaces differently from the rest.
- Reworded the multi-monitor layout help: it now says Auto is side-by-side and Manual
gives a per-display X/Y editor "in the Live displays section below once two or more are
streaming" — instead of pointing at an "arrangement table" that isn't visible until
clients connect.

Two UX fixes on the Virtual displays Configuration card:
- Keep-alive is no longer implicitly "on" by typing in the seconds field. It's an
explicit two-button toggle — **Off** (tear down at disconnect) vs. **Keep for** [N]
seconds — and the seconds input only appears when "Keep for" is selected. The
duration is remembered across toggles, and the help text explains both modes.
- Opened up the cramped custom form: the fields container is `space-y-6` with more
padding (`p-5`, rounded-lg), each option group is `space-y-2.5`, and the Save button
sits below a divider — so it reads as sections with room instead of a pressed stack.

The Host page was crowded (identity, codecs, ports, GPU, displays, compositors) and the
virtual-display config surface is large enough to warrant its own home.
- New **Virtual displays** nav section: `/displays` route + `sections/Displays` (moved
DisplayCard out of `sections/Host`), a `MonitorPlay` sidebar entry after Host, and
`nav_displays` i18n. Removed the displays card from the Host page/view.
- On its own page the card splits into two: **Configuration** (presets + custom axes) and
**Live displays** (the live list + arrangement table) — room to breathe.
- Presets now render in a max-2-column grid (`sm:grid-cols-2`) with larger padding, a bigger
section heading + preset titles (text-base semibold), roomier spacing, and bottom-aligned
"what it sets" badges so the cards line up.

The Virtual displays card previously only exposed keep_alive/topology/max_displays as
editable custom fields; conflict/identity/layout (enforced since Stages 3-5) had no
controls, and the presets weren't surfaced as one-click options. Rework the card so the
whole policy is configurable WITHOUT any client connected:
- Presets front-and-center: each of the five (default/shared-desktop/hotdesk/workstation/
gaming-rig) is a one-click row showing its story AND what it sets (keep-alive · topology ·
conflict · identity badges), highlighting the active one. A click applies it immediately.
gaming-rig stays disabled + "coming soon" (keep_alive: forever isn't cross-platform yet).
- Custom mode reveals EVERY axis editably — keep-alive, topology, conflict, identity, layout,
max-displays — seeded from the current effective behavior, with a Save button. A reusable
`Choice` button-group + a tolerant `tr()` label lookup keep it tidy.
- The live-display list + multi-monitor arrangement table stay below (they need a live
session); the settings above work standalone.
- en+de i18n for the new controls; refreshed the effective-preview row to show all axes.

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.

FEC/Reed-Solomon packetization ran inline on the encode loop (~3 ms/frame at 4K),
serializing behind encode and capping the GameStream frame rate below what the
encoder alone can sustain. Split it into a 3-stage pipeline, each stage on its own
thread joined by a depth-2 bounded queue:
encode loop → [raw AUs] → packetizer (FEC/RS) → [wire batch] → paced sender
- `spawn_packetizer`: turns each `RawFrame`'s access units into wire datagrams via
the stateful VideoPacketizer, off the encode loop. Above-normal priority (on the
per-frame critical path). Tallies goodput (bytes to the wire) for the stats window.
- Backpressure chains up: a slow sender blocks the packetizer, which fills the
encode→packetizer queue, which makes the encode loop drop the NEWEST frame — encode
itself never waits.
- A dropped frame now consumes no client-visible frameIndex (packetization is
downstream), so the host re-anchors the reference chain: a drop arms a keyframe on
the next iteration (`recover_after_drop`), routed through the same coalesce gate as
client IDR requests so a burst of drops (congestion) can't become an IDR storm.
- Perf/stats relabeled: `pkt` = AU drain, `send` = enqueue to the pipeline (both
should be near-zero now; nonzero = encode being stalled by pipeline backpressure).
Goodput read from the packetizer's atomic at the 1 s stats boundary.

Completes Stage 5's web piece (design/display-management.md §6.2): a `DisplayArrangement`
editor in the Virtual displays card. For a ≥2-display group, it renders an x/y table over
the live displays that carry a stable identity slot (the manual-layout key), seeded from
the current computed positions; Save writes `PUT /display/layout` (via the generated
`useSetDisplayLayout`), which switches the host to a manual layout applied from the next
connect. Shared/anonymous displays (no identity slot) are omitted (they can't be pinned).
Also refreshes the now-stale `display_pending_note` copy (conflict/identity/layout ARE
enforced as of Stages 3-5) in en + de.

Host-side completion of Stage 5 (§6A many-clients-as-monitors), all unit-tested;
two-session on-glass validation still pending (no GPU on the dev VM):
- Per-group topology restore (§6.1): the KWin `exclusive` restore no longer rides
the per-session StopGuard (which re-enabled the physical the moment the FIRST of
several exclusive sessions dropped, under a live sibling). KWin hands its restore
to the registry as a closure (new trait `take_topology_restore`); the registry
keeps it in the display group (`Entry.topology_restore`) and, on teardown, floats
it to a surviving same-group sibling (`hand_off_restore`) or runs it when the group
empties — outside the lock, before the last output's keepalive drops, so the
compositor never sees zero outputs. All three teardown paths (lease drop / linger
expiry / mgmt release) honor it. Single-display path byte-for-byte unchanged.
Unit-tested: float / run-on-last / non-carrier-first / never-cross-backend.
- Mutter group-aware (new trait `set_first_in_group`): the registry tells each
backend whether it's the first display of its group; a non-first Mutter session
EXTENDS into the already-exclusive desktop instead of re-applying a sole-monitor
ApplyMonitorsConfig that would disable the first session's virtual. (Mutter
connectors are un-nameable, so it can't build a keep-all-virtuals config; skipping
is the safe equivalent.) Single-session unchanged. Residual APPLY_TEMPORARY revert
documented.
- gamescope groups (§6.1): `registry::group_key` makes each gamescope spawn its own
group (independent nested session, no shared desktop) — never auto-rowed against or
restore-/topology-grouped with another gamescope. Applied in both the /display/state
assembly and the acquire-time position computation. Unit-tested.
Remaining Stage 5: the web console arrangement table, on-glass validation, and the
documented residuals (wlroots exclusive, Mutter APPLY_TEMPORARY). design doc updated.

§6A layout, riding the Stages 1-3 registry with no protocol change:
- vdisplay/layout.rs: pure arrangement engine — auto-row (left-to-right in
acquire order, top-aligned) + manual (per-identity-slot offsets, auto-row
fallback for unpinned members). Unit-tested.
- Registry group model (Linux): group = backend (one desktop per compositor
session). /display/state groups entries, orders by acquire (gen), and computes
each member's position via the engine (pure `assemble_displays`, unit-tested).
DisplayInfo carries group/display_index/position/identity_slot/topology. The
backend reports its resolved slot via the new VirtualDisplay::last_identity_slot
(KWin only), so the arrangement + state key on per-client identity.
- Registry-driven position apply: new VirtualDisplay::apply_position(x,y) (default
no-op; KWin drives kscreen-doctor). Right after create the registry computes the
new display's position over its whole group (pure `position_for_new`, unit-tested)
and applies it — one seam for BOTH deterministic auto-row AND manual placement.
Guarded: the origin (0,0) is skipped, so a single-display / first-of-group session
(and every non-KWin backend) issues no positioning — the historical single-display
path is unchanged. On-glass-validation-pending.
- PUT /api/v1/display/layout: persists the console's manual arrangement via the pure
EffectivePolicy::with_manual_layout transform (locks current effective behavior
into explicit Custom fields + sets a manual layout, so arranging is orthogonal to
the other axes). OpenAPI regenerated.
- /display/settings `enforced` now lists all five axes (keep_alive, topology,
mode_conflict [Stage 4], identity [Stage 3], layout [Stage 5]) — was stale at
keep_alive+topology; the console reads it to know which controls are live.
Still Stage-5 TODO (design/display-management.md §11): Mutter/wlroots group-aware
analogues, per-group topology restore, the web arrangement table, gamescope decline.
cargo build/test/clippy/fmt green; OpenAPI in sync.
