A controller that reaches the host by USB passthrough — VirtualHere and friends, or simply a
pad plugged into the host — arrived there twice: once as the real device, once as the virtual
pad this client built from the same hands. Games read both, so a stick drifts against the
centred second pad and menus take every input twice.
New per-client setting, "Forward controllers", default on (today's behaviour). It is tier-P,
so a profile can decline what another profile forwards.
On Linux and Windows it is deliberately stronger than "send nothing". Opening a controller is
what CLAIMS it — SDL's HIDAPI drivers take the device node — and a claimed device is one a
passthrough tool cannot bind, so with this off the session opens no slot at all and never
enables the Valve HIDAPI drivers. Menu navigation is untouched: the launcher still opens the
active pad, and a session supersedes menu mode whether it forwards or not, so the pad is free
for the whole time a stream is up. The consequence, documented at both the setting and the
chord: the controller escape chord is read off forwarded pads, so it is unavailable there.
The Apple and Android input stacks claim nothing, so those clients keep their slots and their
chords and only gate the wire sends — losing tvOS's only controller way out of a stream would
have been the worse bug. Android does stop its DualSense and Steam Controller 2 USB captures,
which do claim the device.
Surfaces: GTK, WinUI, the console settings screen, Apple's touch and gamepad settings, the
Android touch and gamepad settings, and Decky (which also hides the rows that now have nothing
to act on). Everywhere the "which pad" and "pad type" rows grey out while it is off.
Verified: cargo clippy --all-targets -D warnings + 79 tests on pf-client-core, pf-console-ui,
punktfunk-client-session and punktfunk-client-linux (linux/amd64 container, gate proven
non-vacuous with a planted error); swift build for the Apple clients; gradle compile + 49 unit
tests for Android (likewise proven); tsc for Decky. clients/windows is UNCOMPILED — both
Windows boxes were offline; its edits were reviewed against the helper signatures by hand.

iPadOS releases the scene's pointer lock by itself when Escape is pressed — the platform's
built-in "let me out", mirroring the web Pointer Lock API's default unlock gesture. Nothing in
our code does it: a bare Esc never touches `captured`, and it keeps forwarding to the host as
the game key it is. But the lock going away flips the mouse onto the absolute UIKit path and
un-hides the iPadOS cursor, so pressing Esc for an in-game menu silently cost the capture until
the user clicked into the video to win it back.
Esc is a GAME key in a stream, not a request to hand the pointer back to iPadOS, so an unwanted
drop is now re-requested. `syncPointerLock` arms a short, bounded burst (3 attempts over ~0.6 s,
no restart inside 2 s) whenever the lock is wanted, was previously HELD, and is now gone; the
first attempt re-asserts `prefersPointerLocked`, later ones present a real false→true transition
and re-anchor the PointerLockChain. Every deliberate release (⌘⎋, ⌃⌥⇧Q, the Stream menu,
resigning active) clears `captured` first, so `wantsPointerLock` is already false when their drop
is observed and none of them are fought.
The "previously held" half of the condition keeps a scene that never qualifies (Stage Manager,
Split View) from paying for a lock that isn't coming — there, a first grant is still driven by
the chain engage in setCaptured/viewDidAppear exactly as before.
While a re-lock is in flight the local cursor stays hidden and absolute pointer MOTION stays
muted, so the couple of frames it takes read as "Esc did nothing to my mouse" rather than a
cursor that blinks in and out and a host cursor that teleports to the pointer's absolute
position. Buttons still forward (they carry no position), so a click mid-relock isn't swallowed.
The burst clears itself on give-up, so the cursor can never stay hidden on a lock the system
won't grant.

Until now the only way to stop sending the room was to end the session and turn
"Send microphone to the host" off in Settings — a per-app setting for something
that is really a per-conversation act. The mic now mutes from inside the stream:
a button on the HUD card, the Stream menu's ⌃⌥⇧A (macOS menu bar and iPad
hardware keyboards), the same chord while input is captured (both platforms
detect it in InputCapture, where the reserved ⌃⌥⇧Q/D/S already live — ⌃⌥⇧M is
the mouse-model flip, cross-client, so the mic gets A), and on iPhone/iPad a mic
disc beside the touch exit for the stats tiers whose HUD carries no buttons.
Muting is local and instant: it gates capture on this device, the host is never
asked and never told. The muted state gets its own badge over the stream —
independent of the stats overlay, because "am I muted?" is not a statistic and
the overlay is exactly what a player turns off. The badge is also the way back:
tapping it unmutes, which is the guaranteed path for a touch user who muted with
the overlay off.
Mute is session state and is deliberately not persisted. Every stream starts live
if the mic is enabled at all, rather than carrying a mute nobody remembers making
into a call three days later.
The mechanism is the one wave 1 built. `SessionAudio.setMicMuted` — which mutes
the voice processor's input on the combined engine and pauses the capture engine
on the split one — stays the single muting path; what changes is that it now
takes an EFFECTIVE mute the session composes from its two reasons: the user's
mute and the background keep-alive's privacy mute. Neither can clear the other,
so a user who muted before pocketing their phone comes back still muted, and
backgrounding no longer un-mutes anyone on return. It also latches the state, so
a mute made while the microphone permission prompt is still open lands on the
engine that grant creates instead of being lost.
The control is offered only where there is something to mute: the session's
resolved `micEnabled` (a profile can turn the mic on or off), a platform with an
app-accessible input (never tvOS), and a TCC grant the OS hasn't refused. Absent
rather than greyed on the HUD and the touch discs, greyed on the menu, and the
macOS start-of-stream banner only teaches ⌃⌥⇧A when the session actually sends a
microphone.

The Apple client on a loudspeaker was the primary reported echo source:
two AVAudioEngines by design (arbitrary mic/speaker pairs, two clocks)
meant no unit ever saw render and capture together, which is exactly
what setVoiceProcessingEnabled needs. With the mic enabled and the new
"Echo cancellation" toggle on (both defaults), playback and capture now
share ONE engine with the system voice processor engaged — AEC, noise
suppression and AGC — and the input node's other-audio ducking pinned
to .min with advanced ducking off, because this is a game stream, not a
call: the host's audio must never dip under the outgoing voice.
The two-engine path survives where it is the right answer: echo cancel
off, macOS sessions with a hand-picked speaker/mic UID or input channel
(the voice processor only follows the system default devices, and its
capture side is its own mono mix — a per-channel pick can't survive
it), and any machine whose voice processor refuses to engage. Every
failure falls back to a working configuration rather than silence. The
capture chain reads the input format after the processor is enabled,
so its mono/lower-rate output flows through the existing converter
unchanged; a first-run permission grant swaps the playback-only engine
for the combined one in place, reusing the same jitter ring and drain
thread; background mic muting mutes the processor's input instead of
pausing the shared engine (playback keeps running).
echo_cancel rides the full settings plumbing micEnabled has — defaults
key, effective settings, profile overlay (serialized as `echo_cancel`;
the Rust catalog carries it via unknown-key passthrough until it grows
the field), a captioned toggle beside the Microphone row, and a gamepad
settings row. tvOS behavior is untouched (playback only, as before).

The capture path carried three latencies that had nothing to do with the
network: a 2048-frame tap request (42.7 ms bursts before the first
sample could even be sliced), 20 ms Opus framing, and a mono signal
duplicated into both stereo channels because the encoder was configured
like the downlink. CoreAudio's Opus encoder takes mFramesPerPacket=480
and mChannelsPerFrame=1 just fine — probed empirically: the converter
truly emits 10 ms mono CELT packets (TOC config 30), one per 480-frame
chunk, and the stereo-shaped decoder upmixes them with the tone intact —
so the uplink now asks for 10 ms tap buffers and encodes 48 kbps mono
10 ms packets, with 960 kept only as an init-time fallback. The host
decodes any Opus frame ≤120 ms, so nothing changes on the wire's far
end.
The tap thread also stops burning cycles per callback: the mono fold and
resampler scratch buffers are allocated once (regrown only if a larger
device quantum ever arrives), and the chunk slicer walks a head index
instead of removeFirst — which memmoved the entire backlog for every
packet on a render-adjacent thread. iOS additionally asks the session
for 5 ms IO quanta at 48 kHz when the mic is on (best-effort; the
hardware decides).
Verified: swift build (macOS arm64), swift test OpusCodecTests +
AudioChannelFoldTests, and an iOS arm64 cross-build; the 480/mono
behavior confirmed by TOC inspection on macOS 15.

UIKit delivers Pencil events at the PANEL's cadence, and the deadline
link's rate hint pins the panel to the stream rate (min = preferred =
stream Hz, deliberately — the anti-idle-stall floor). Net effect: a 60 fps
stream on a 120 Hz iPad silently halved pencil sampling, 8.3 → 16.7 ms per
event batch — exactly the workload (drawing) that feels it most.
FrameRateHint gains a boost that lifts min/preferred to the range ceiling
while a Pencil is in range (hover or contact): PencilStream surfaces
proximity transitions from its emit() choke point, the view controller
debounces release by 2 s (edge-of-canvas hover flicker must not thrash the
link), and Stage2Pipeline/SessionPresenter stage it like the rate hint —
applied from the link's own thread, no-op under arrival/glass pacing.
Presents still pace at stream rate (extra updates vend into the
newest-wins stash), so the cost is empty link wakes scoped to proximity.
pf.present logs engage/release for on-glass verification.

Phase-locked capture had no client half on Apple — the host's v3 controller
(grid-locked submits, coherence-gated engage) shipped with only the Android
reporter feeding it. Now the stage-4 link thread flushes the same v2
circular arrival-phase statistic at ~1 Hz:
- PhaseReporter (Stage2Pipeline): the decode callback deposits per-AU
reassembly-completion stamps, the CAMetalDisplayLink update deposits the
latch grid (period = window-min of update spacing), and the flush ports
punktfunk_core::phase::circular_latch verbatim — a period-smeared Wi-Fi
link reads coherence ≈ 0 and the host correctly never engages; a wired
link opens the gate. Binds/unbinds per session like DecodeReport.
- PunktfunkConnection.reportPhase wraps the existing ABI entry point.
- Hello honesty: iOS/tvOS advertise CLIENT_CAP_PHASE_LOCK (macOS stays
without — the stage-2 arrival presenter has no latch grid), Android now
sets the bit its reporter already earned, and the ABI grows the
PUNKTFUNK_CLIENT_CAP_PHASE_LOCK mirror const (header regenerated).
Advisory in v1: the host arms on report receipt.
- Stage-3 doc comment no longer calls itself the tvOS default (stage-4 took
that over in the 2026-07 rebuild).

Three drawing-path defects on the pen clients:
- The Apple in-range heartbeat was re-armed on every emit (~120 run-loop
mutations/s during a stroke) and lived in .default run-loop mode only — a
tracking-mode excursion >200 ms with a stationary pen crossed the host's
force-release failsafe and dropped the held stroke. Now one long-lived
50 ms timer in .common mode, resending only after ≥50 ms of send silence.
- Both clients TRUNCATED an over-8-sample coalesced run instead of splitting
it into consecutive batches (the send_pen contract): Apple suffix(8)
dropped the oldest samples, the Android JNI clamped count. An over-cap run
means the UI thread hitched — exactly when dropping stroke geometry hurts
most. Apple splits in emit(); the Android JNI loops send_pen over ≤8-sample
chunks (Kotlin's per-emit ceiling is now 64 = a >250 ms stall).
- The iOS letterbox mapper did a lock+FFI currentMode() read per coalesced
sample on the main thread, contending the ABI lock the batch send takes
next — now a 250 ms TTL cache (mid-stream requestMode still tracked).

The Apple and Android apps carry their own copy of THIRD-PARTY-NOTICES.txt
and show it on the acknowledgements screen. `7fc2775f` refreshed the root
file but not the copies — running the python generator directly skips the
sync `scripts/gen-third-party-notices.sh` does — so they had drifted to a
531-crate snapshot that predates the whole vendored-source section.
That section is where the OS marks' attribution lives, so both apps have
been shipping Font Awesome's CC BY 4.0 icons with no attribution visible
at all. Re-synced, which also carries the Bazzite Apache-2.0 notice the
previous commit adds.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Three things were wrong with the host-card OS icons.
The Windows mark was Font Awesome 5's, which is still the Windows 8/10 flag
with the perspective skew — dated next to the flat four-pane mark Microsoft
has shipped since Windows 11. No icon set has the current one (Simple Icons
carries no windows/microsoft slug at all), so it is drawn here: four equal
squares at the authentic 11.377 + 1.246 proportion. The Decky plugin was
pulling FaWindows straight from react-icons, so it now inlines the masters
like the web console does, or it would have kept the old flag regardless.
Bazzite, CachyOS and Nobara collapsed onto their family's mark. The host
already advertises the full chain, so this is purely missing art: all three
now ship a leaf mark, because "a Bazzite box" and "a Fedora box" are
different machines to the person reading the card. CachyOS and Nobara come
from Simple Icons; Bazzite has no icon anywhere, so its "b" is lifted out of
the project's own badge (Apache-2.0, attributed).
On Android every non-square mark was stretched. A VectorPainter maps the
viewport onto the ImageVector's default size with independent x and y
scales, so declaring a 448x512 Tux as 24x24 dp squashed it — silently, no
crash, no warning. The longest viewport edge now sets the 24 dp box and the
other follows the ratio, which is what Icon()'s ContentScale.Fit expects.
A unit test pins the invariant; every other client was already correct.
Also: scripts/gen-os-icons.sh replaces the undocumented hand-run pipeline
that turns a master into the GTK symbolic SVG, the Windows PNG and the Apple
template PDF. It reproduces the committed artifacts byte-identically.
Verified: web and Decky typecheck, Decky bundles, Android compiles and its
tests pass, PunktfunkKit builds, osinfo's tests pass. Not verified on glass,
and the GTK/Windows client crates do not build on macOS.

`DiscoveredHost` reads the new `os=` TXT (sanitized in PunktfunkShared's
OsChain.swift — the pure grammar + walk, mirrored from pf-client-core so every
platform resolves identically, and dependency-free so the widget could use it);
`StoredHost` appends optional `osChain` per the frozen app↔widget contract
(optional + appended last; legacy JSON still decodes, pinned by the round-trip
tests), and `HostStore.updateOsChain` learns it beside the MACs.
The art rides PunktfunkKit's proven resource path (the fonts precedent): ten
template vector imagesets in Resources/OsIcons.xcassets, compiled by the Xcode
build into the Kit bundle's Assets.car (verified: all ten resolve in the built
app) and tinting via foregroundStyle like an SF Symbol. Saved and discovered
cards lead their status line with the mark; a host that advertises nothing
renders exactly as before. GamepadHome tile + widget marks are follow-ups.

The Apple half of settings profiles (design/client-settings-profiles.md §4) starts
with the thing the desktop shells got for free from the shared Rust core: a model,
and one place that resolves it.
`SettingsOverlay`/`StreamProfile`/`ProfileCatalog` mirror `pf-client-core::profiles`
field for field, unknown-key carry-through included — an older build that opens a
profile a newer one wrote must not gut it on save. The catalog lives in the App
Group suite beside the saved hosts, because the things that point at it are fields
on the host record: `StoredHost` gains `profileID` and `pinnedProfileIDs`, both
optional and appended last, because that JSON is a widget contract.
`EffectiveSettings` is the resolution — globals with the session's overlay on top,
computed once at connect and latched in `SessionSettings` for the rest of it. That
latch is the point. Ten sites across the app AND the kit read `UserDefaults`
directly mid-session (the presenter's priority and VRR, the vsync flip, the
match-window follower, the scroll sign, the touch model, the mouse model, 4:4:4,
the audio endpoints); a profile that reached some of them and not others would be
worse than no feature at all. They now read the latch, which off-session is the
plain globals — byte for byte what they saw before.
The deep-link grammar grows up with it: `DeepLink` becomes a full port of
`deeplink.rs` — routes, host-ref forms, `fp`/`host` recovery, one-off `profile`,
and every refusal code — and the Swift suite now runs
`clients/shared/deeplink-vectors.json` itself, read from the source tree so there
is no second copy to drift. All 44 cases green. The router refuses what it can't
honor by name: a profile that doesn't exist, an ambiguous one, a fingerprint that
contradicts the pin. A shortcut that streams with the wrong settings is worse than
one that explains itself.

Three separate things an iPad's keyboard and mouse got wrong.
Every mouse button past the first two clicked LEFT on the host. UIKit's
button mask is 1-based over the HID order, and only `.secondary` was read —
middle, back and forward all fell into the `else` and became button 1. Map
3/4/5 through `.button(_:)`; only middle and right swap places, because the
wire numbers them the other way round.
Holding a key deleted exactly one character. GameController reports a key
once on press and once on release — it has no repeat channel — and the host
injects exactly what it is told, so nothing downstream ever turned a held key
into a stream of presses. Generate the repeat client-side at the usual
delay-then-rate, newest key only, with modifiers and lock keys excluded.
macOS was never affected: NSEvent hands it the window server's own repeats.
Scrolling ignored the system's Natural Scrolling switch. UIKit has already
applied that preference by the time it hands over a pan translation — it is
what makes every UIScrollView on the device turn the right way — so negating
y pinned the stream to traditional scrolling and inverted the setting for
everyone on the default. Pass the sign through, exactly as the macOS path
passes `NSEvent.scrollingDeltaY` through, and let that one recognizer own
scroll under pointer lock too: it is the only way trackpad two-finger
scrolling ever arrives, so gating it on the lock had been dropping it
entirely there, and the raw GameController axis it deferred to carries no
such preference. iOS installs no GCMouse scroll handler now, so nothing
double-sends; tvOS, which has no scroll pan, keeps it.

`pf_dualsense.inx` gave all four hardware ids a single %DeviceDesc%, so Device
Manager labelled an emulated DualShock 4, DualSense Edge and Steam Deck pad
"punktfunk Virtual DualSense". The HID layer was always per-type — device_type
picks the PID (09CC for DS4), the report descriptor and the product string — but
the one place a user goes to check said DualSense for every choice, which reads
exactly like the controller-type setting being ignored.
Split into four model lines over the same install section, one description each.
No binding, service or descriptor change; stampinf's 9.9.MMdd.HHmm DriverVer
increments on every build, so pnputil takes the update. InfVerif on the WDK
runner: INF is VALID.
Also correct the Slot.pref comment from the previous commit: emulating a
DualShock 4 gives up adaptive triggers by construction. HidOutput::Trigger is
emitted only by dualsense_proto, and a DS4 has no trigger-effect reports — the
host never generates any to send. Rumble and the lightbar remain.

The "Controller type" setting reached the Hello and stopped there. Every pad then
opened with a GamepadArrival carrying its DETECTED kind, and the host builds each
virtual device from that arrival — the session default is only the fallback for a
pad that never declares one. So "emulate my DualSense as a DualShock 4" put a
DualSense on the host the instant the controller connected, and no amount of
reconnecting helped. Apple and the native clients both; Android already applied
the setting per pad.
The setting now rides the declaration too: explicit wins for every slot, Automatic
keeps per-pad detection so a mixed session stays honest. The physical kind still
drives the LOCAL feedback paths — a DualSense emulated as a DualShock 4 keeps its
lightbar and adaptive triggers, and a Deck keeps its rumble keep-alive.

`resetCursorRects` wore the host shape only when `hostCursors[st.serial]` hit,
and fell through to `invisibleCursor` on a miss. But a miss is the ROUTINE case,
not a degenerate one, and it is not a reason to hide the pointer:
* State (0xD0) is a per-frame datagram and announces the new serial the moment
the host QUEUES the bitmap on the reliable control stream, so on every single
shape change the client knows a serial before it holds the pixels.
* The shape ring drops the NEWEST under burst (CURSOR_SHAPE_QUEUE = 8) and the
host never re-sends it — it only sends on a serial CHANGE — so a dropped
serial stays un-backed until the pointer next changes shape. Crossing a
toolbar flips arrow/I-beam/hand/resize several times a second, and each flip
mints a fresh serial and a fresh bitmap, so bursts are ordinary.
Either way the pointer BLINKED OUT rather than lagging, and in the dropped case
it stayed gone for as long as the pointer held that shape — reported on glass as
"the I-beam never appears over text fields, every other cursor is fine".
Hold the last worn shape across the gap: only `st.visible == false` (the host
says the pointer is hidden) may hide it now, never a missing bitmap. Worst case
is a briefly stale pointer. This also makes two comments that already claimed
this behaviour true — the shape-rejected warning's "keeping the previous cursor"
and CURSOR_SHAPE_QUEUE's healing claim, both of which were fiction.
Host side is exonerated: on .221 the poller sees the I-beam handle (0x10005,
CURSOR_SHOWING set), and the monochrome AND-over-XOR conversion renders a correct
glyph — black beam, white outline — so the bitmap that goes on the wire is good.
swift build PunktfunkKit + cargo check punktfunk-core green; on-glass owed.

The flagship leg of design/pen-tablet-input.md §7: against a HOST_CAP_PEN host
the Pencil splits out of the finger path (independent of touch-input mode) into
PencilStream — state-full samples with force→pressure, altitude→polar tilt,
azimuth (+90° to the wire's north-clockwise convention), Pencil Pro rollAngle→
barrel roll (17.5+), coalesced touches batched ≤8/send for full 240Hz fidelity,
and Pencil hover (zOffset>0 distinguishes it from trackpad hover) as in-range
samples with distance. Squeeze holds barrel 1, double-tap clicks barrel 2 (the
Pencil has no hardware buttons/eraser — these are how host apps get those
affordances). Implements the ≤100ms heartbeat wire contract (80ms timer) so a
stationary held stroke survives the host's 200ms dead-client failsafe. Toward a
pen-less host nothing changes (Pencil stays a finger).
Also fixes hostSupportsCursor testing the STALE 0x04 bit — HOST_CAP_CURSOR
moved to 0x08 when TEXT_INPUT claimed 0x04; the old test would mistake a
text-input host (e.g. Windows) for a cursor grant and double-render the pointer.

The Mac client drew the host-forwarded cursor bitmap at its native pixel
size (pixel-as-points), so the on-screen pointer tracked the HOST's display
scaling: a 4K/high-DPI virtual display renders a 96 px pointer, which then
appeared huge on the client — and on retina every pointer was already
2x-inflated and upscaled-blurry, since the backing scale was ignored.
Cache the shape raw and rebuild the NSCursor at the live video-fit factor
(fit.width / mode.width — the same AVMakeRect fit the input mapping uses)
on each apply, re-fitting on resize / retina moves. The pointer now renders
at its true size relative to the streamed desktop at any host scaling:
crisp and 1:1 with the video at 100%, and proportional (not ballooning)
when the host sits at 200-300% — including a deliberately raised scale.
iOS/tvOS (UIPointerInteraction) and Android (no forwarded-bitmap path)
render the pointer differently and need no change; the SDL/Linux client has
the same native-size issue and will follow.

cursorChannelActive/hostCursors/cursorState stayed latched across

On-glass (Mac ↔ Windows M2c host): the host cursor's VISIBILITY is not a
usable 'a game grabbed the mouse' signal — Windows hides the pointer for
ordinary desktop activity (clicking, typing). The per-frame forwarder
turned those transients into relative_hint=true, so the client flipped
desktop→capture→desktop, which (a) warped the cursor to view-centre and
(b) flushed held buttons via releaseAll — a spurious mouse-up ~200 ms
into every press that broke window dragging/resizing.
Disable the auto-flip; the mouse model stays user-driven (⌃⌥⇧M). The
hint still rides the wire, unused, for a future M3 that keys off a REAL
pointer-lock signal (host-side ClipCursor/raw-input detection) instead
of visibility.

The Mac client now exercises the full cursor channel against capable
hosts: desktop-mode sessions advertise CLIENT_CAP_CURSOR, the host
stops compositing the pointer, and StreamView draws the forwarded
shapes as the real NSCursor — plus the M3 host-driven model flip.
- ABI v11: punktfunk_connect_ex9 (adds client_caps; ex7/ex8 pass 0 —
Android untouched), PunktfunkCursorShape/State + the two
next_cursor_* poll fns (audio-style borrow contract), and
PUNKTFUNK_CLIENT_CAP_CURSOR. Fixed in passing: the first insertion
split next_host_timing's cfg/no_mangle attributes off the fn, which
silently dropped the symbol from the header AND dylib — caught by
the Swift build, reattached with its docs.
- PunktfunkConnection: clientCaps connect param, hostSupportsCursor,
CursorShapeEvent/CursorStateEvent + nextCursorShape/nextCursorState
(one cursor thread drains both planes; cursorLock joins the close()
ladder).
- SessionModel: desktop-mode sessions (DefaultsKey.mouseMode) connect
with the cursor cap on macOS.
- StreamView: shape cache (serial → NSCursor, straight-alpha RGBA via
CGImage), resetCursorRects wears the HOST shape while the desktop
model is engaged (hidden host pointer ⇒ invisible), latest-wins
state pump, and the M3 auto-flip — edge-triggered on relative_hint,
⌃⌥⇧M sets an override latch cleared by the next host edge, leaving
relative warps the pointer to the host position via the inverse
letterbox mapping (CGWarpMouseCursorPosition, CursorCapture's
coordinate convention).

Folds the parked client-side-cursor machinery (cursorMode auto/always/
never, hidden while disabled) into the cross-client mouse model:
MouseInputMode capture|desktop under DefaultsKey.mouseMode, picked in
Settings ▸ Keyboard & mouse (macOS), resolved at session start and
gated off on gamescope hosts (relative-only EIS).
Desktop model = the un-neutered absolute path with the SDL cursor
policy: pointer never disassociated (enters/leaves the stream freely),
monitor forwards letterboxed absolute positions, and the local cursor
hides only while over the view via an invisible-cursor rect (the
host's composited cursor is the one you see; AppKit manages the rect,
so no hide/unhide balancing). ⌘⇧C becomes ⌃⌥⇧M — the same chord as

Task 1 (latency): the transactional present now commits from the RENDER
thread inside an explicit CATransaction + flush() instead of hopping to
main. The present harness (2026-07-21, 240 Hz Studio, full-size window)
measured the main hop batching presents at runloop-iteration rate when
main is busy — an active implicit transaction NESTS the explicit one —
which is the field's presents=55 @ fps=240 / display_p50 18.6 ms.
Off-main commits measured immune to main churn: glass p50 ~10 ms,
cadence a clean 4.17 ms at 240. flush() is load-bearing: without it the
render thread's own implicit transaction (drawableSize/colour writes)
swallows the explicit commit and NOTHING reaches glass — the harness
reproduced the exact freeze (every present dropped). Legacy main-hop
kept as PUNKTFUNK_TXN_PRESENT=main for field A/B. New pf-windowed
Console line (subsystem io.unom.punktfunk, category presenter)
decomposes the issue side per second.
Task 1 lever D: the f407f418 IOSurface contents-swap path is
resurrected format-aware as WindowedPresentMode.surface — bgra8 SDR /
rgba16Float+PQ-tagged HDR pool, swap committed off-main from the
completion handler; EDR anchored by the metal layer underneath.
Env-only prototype (PUNKTFUNK_WINDOWED_PRESENT=surface) until the HDR
composite is eyeballed on glass.
Task 2 (setting): punktfunk.windowedSafePresent (default ON =
transactional mitigation; OFF = the fast async path whose panic the
saga is about — the caption says so in plain words). Rows in the touch
Settings (Presentation) and gamepad settings, macOS-only.
PUNKTFUNK_WINDOWED_PRESENT=async|transaction|surface overrides for dev
A/B. maximumDrawableCount stays 3 — the harness measured 2 starving the
render loop (172/s) and worsening glass p50.

The windowed-macOS "mismatched swapID's" @UnifiedPipeline.cpp kernel
panic is the CAMetalLayer ASYNC image queue (commandBuffer.present,
mandatory with displaySyncEnabled=false) diverging from WindowServer's
compositor on a high-refresh composited session — it survived glass
pacing (PyroWave, 2026-07-18) and hit windowed HEVC on the same 240 Hz
Mac Studio (2026-07-21), so it's the async queue itself, at any codec
or pacing.
f407f418's mitigation routed windowed PyroWave through a BGRA8 IOSurface
layer.contents pool, which cannot carry HDR — extending it to HEVC would
have tone-mapped windowed HDR down to SDR. Instead, present the drawable
through a Core Animation transaction (CAMetalLayer.presentsWithTransaction)
for every windowed session: commit, waitUntilScheduled, then drawable.present()
inside a CATransaction, so the swap commits with the layer tree and stays
in lockstep with the compositor instead of racing it. The full
rgba16Float / PQ / EDR render path is untouched — windowed HDR is real
HDR again. Fullscreen keeps the async path (direct scanout, lowest latency,
no panic there).
Removes the IOSurface surface pool, its surfaceLayer sibling, and the
macOS windowed PQ->SDR tone-map (tvOS keeps its no-headroom tone-map).
Net -150 lines. swift build + 169 tests green. Needs on-glass soak on
the 240 Hz Mac Studio (kernel race — only real hardware confirms).

The two-pair investigation (wired Mac clients stuck at a rock-steady
~18-19 ms "network" that survived the load ending and cleared only on
reconnect) exposed two structural gaps, one of measurement and one of
recovery:
- Receipt was stamped at the hand-off PULL (Swift nextAU, pf-client-core,
Android decode loops), not at reassembly completion — so any client-side
standing state between the reassembler and the pull read as NETWORK
latency, undiagnosable from the HUD. ABI v9: `PunktfunkFrame`/`Frame`
grow `received_ns`, stamped by `Session::poll_frame` as the AU crosses
the session boundary. Every embedder now uses the core stamp; the Apple
client keeps the pull instant as `AccessUnit.pulledNs` and shows the
receipt→pull wait as its own "client queue" term (detailed HUD tier from
2 ms + a `queue_p50` stats-log field). Decode stages keep their pull
anchor on all platforms, so no historical stage shifts meaning.
- The jump-to-live detectors deliberately ignore anything under 6 queued
frames / 400 ms behind — so a small, constant, loss-free elevation (a
sub-frame standing backlog, or a stale clock offset after a wall-clock
step/slew) is carried for the rest of the session. New third detector
(`StandingLatency`, unit-tested ladder): window-MIN one-way delay
≥ 10 ms above the session floor with zero loss for ~4.5 s escalates
gently — a free clock re-sync first (an applied re-sync re-bases the
floor), then at most 3 flush+keyframe bleeds sharing the jump-to-live
cooldown, then a loud disarm naming what it means. Loss windows reset
the run: congestion belongs to FEC/ABR, not this detector.
Also: mid-stream re-sync apply/discard logs debug→info — they are the
forensic trail for the stale-offset case and were invisible in the field.

Re-lands the island rebuild: a concurrent session's pull-rebase reordered the
pick against the canvas-previews commit and the pre-rebuild file content won;
the working tree kept the intended final state (BrandColor.swift itself
survived tracked). Content identical to the original commit message:
The widgets rendered system BLUE because Color.brand lived in PunktfunkKit,
which the extension never links — moved to PunktfunkShared (Kit re-exports
Shared). Island rebuilt: expanded = identity leading + elapsed clock trailing
+ one purposeful bottom row (status dot/stage + live latency/bitrate stats
line, End at the trailing edge); compact trailing = the one glanceable number
(live latency green / disconnect countdown orange / state glyph); keylineTint
brand. Lock Screen banner shares the same StatusLine/StatsLine pieces.
swift build + PunktfunkWidgetsExtension build green on the rebased base.

Three real issues from the iPad session-start console:
- Stage444Probe tripped the Thread Performance Checker on every first connect:
the async VT decode (_EnableAsynchronousDecompression) + semaphore wait had
the userInteractive connect Task blocking on VideoToolbox's no-QoS callback
thread — a priority inversion. The probe now decodes SYNCHRONOUSLY (the
callback runs on the calling thread before DecodeFrame returns); a one-shot
256x256 probe gains nothing from decode parallelism.
- The widgets extension declared CFBundleShortVersionString 1.0 against the
0.9.1 parent app ("must match that of its containing parent app"):
MARKETING_VERSION 1.0 -> 0.9.1 in both widget configs.
- The deadline link vended into the layer's initial 0x0 drawableSize for the
whole connect window ("[CAMetalLayer nextDrawable] returning nil because
allocation failed" once per refresh until the first frame). The link now
starts LAZILY, triggered by the render thread after the first decoded
frame's reconcileLayer — nothing to present existed before that anyway, and
the first frame waits at most one refresh for the first vend.
Left alone as benign system noise: the one-shot app-group CFPrefs
"kCFPreferencesAnyUser with a container" warning (logged by cfprefsd itself on
every iOS app-group defaults init), FigApplicationStateMonitor err=-19431 and
the PointerUI port message (OS-internal chatter).

design/apple-presentation-rebuild.md (planning b8e8e41): spend the 2026-07
pacing saga's knowledge. Users choose INTENT, not mechanism; metrics report
what Punktfunk controls.
Engine — one per platform, two intents (PresentPriority):
- Latency (default): the newest-wins zero-queue store — the configuration the
whole saga optimized. Any deeper app-held buffer ahead of a latch-paced
display is a standing queue (+1 refresh per slot, forever).
- Smoothness(K): FrameStore.fifo — a small deliberate jitter buffer (K=1..3,
Automatic=2). Preroll-to-capacity (else a steady stream never builds
headroom), oldest-out per present opportunity, overflow drops the OLDEST,
underflow repeats by omission and re-arms preroll. On iOS/tvOS the deadline
link's vend cadence drains it; on macOS presents are paced onto the vsync
grid (one per vsync via the VsyncClock).
- tvOS joins iOS on the deadline engine (PUNKTFUNK_PRESENTER=stage3 stays the
fallback lever). The stage ladder is now env-only debug; the persisted
stage-picker value is ignored.
Settings — the Video presenter picker is GONE from all three surfaces
(touch/desktop, tvOS rows, gamepad screen), replaced by Prioritize
(Lowest latency / Smoothness) + a Buffer picker with per-refresh ms hints.
New keys punktfunk.presentPriority / punktfunk.smoothBuffer.
Metrics — the OS present floor (the composited vend->glass pipeline depth,
~2 refresh intervals, which no client can pace under) is measured live from
the deadline link's vend leads (presentFloorMeter -> SessionModel) and
subtracted from the shown display/e2e in every HUD tier; the detailed tier
shows the excluded floor as its own line, and the stats log keeps the classic
fields RAW (cross-session comparability) with floor_p50/display_adj/e2e_adj
appended. Self-adapting: reads ~1 interval if direct-to-display ever lands.
pf-present gains qDrop/qDry (smoothness buffer accounting).

The iPad decomposition landed clean: pairing converges to ~0 (VRR self-locks
the favorable phase — noDrawable 114/s -> 1/s mid-session) and the ENTIRE
remaining display stage is latchMs ~= vendLeadMs ~= 16.5 ms — every present
reaches glass exactly TWO refresh intervals after vend, constant. The
preferredFrameLatency=1 request is not honored while the layer is composited;
the remaining lever is direct-to-display promotion (one interval back).
- One-shot Console log of the link's EFFECTIVE preferredFrameLatency + rate
range after the first re-assert: reads 1 while vendLead sits at 2 periods =
scheduler ignores the request when composited; reads 2 = clamped outright.
- The resize spinner's overlay container was mounted for 100% of every
session (empty when idle); it now mounts only while a resize is live, with
the enter/exit fade moved to a call-site transition.

The iPad field read for stage-4 is a phase-locked 21.7 ms display stage
(p95-p50 = 0.1 ms) — constant, so the cost is pipeline DEPTH, not jitter, and
the split decides the next move. Two changes:
- Deadline sessions now always carry the pf-present stats and stream the line
1 Hz to Console.app (subsystem io.unom.punktfunk, category "present") — no
env var / Xcode attach needed on-device. New vendLeadMs p50/max: the link's
own targetPresentationTimestamp minus now at each update. ~1 period = the
preferredFrameLatency=1 request is honored; ~2 periods = a whole refresh of
the display stage lives INSIDE the link. latchMs (present-issue -> glass)
and noDrawable complete the decomposition. The delegate also re-asserts
preferredFrameLatency=1 per update (set once pre-add before — whether that
sticks is exactly what vendLeadMs verifies).
- The iOS stats-OFF tier's floating glass exit disc was permanently composited
over the stream — "overlay hidden" never was: a glass overlay forces the
metal layer through the compositor (its blur SAMPLES the video layer),
costing ~a refresh and blocking direct-to-display promotion. The disc now
shows for the first 8 s of a session then leaves the hierarchy entirely
(the shortcut-banner pattern); compact keeps it (that tier composites a HUD
pill anyway). Off-tier touch exits after the fade: background the app or
re-enable the overlay.

session's pf-client-core edits; this commit is Swift-only.

Session-start bootstrap deadlock in the deadline presenter (4fe3b779): the
CAMetalDisplayLink vends from the layer's CURRENT config, and the layer starts
at drawableSize 0 (never tracks bounds; the sublayer isn't even laid out when
the link spins up). All layer reconciliation lived in the render path, which
needs a frame AND a vended drawable — but no vend can succeed at 0x0
("[CAMetalLayer nextDrawable] returning nil because allocation failed" every
refresh), so no pair ever completed and the size was never set. Black screen.
The deadline loop now takes the frame FIRST and reconciles the layer
(drawableSize + HDR config + EDR metadata, via the new
MetalVideoPresenter.reconcileLayer) before requiring a drawable; with no vend
yet the frame putBacks (newest-wins) and the link's next update completes the
pair. Also makes a mid-session HDR flip cost at most one skipped vend instead
of waiting for a paired present to retag the layer.

Field verdict on the depth-2 gate (M4 iPad Pro, 2752x2064@120): display stage
22-28 ms vs depth-1's 14 — a REGRESSION, not the predicted 5-8. Post-mortem:
any bounded-FIFO pacing keeps a STANDING queue on the always-vsync-latch
platforms. One burst fills every admitted slot and, with arrivals and latches
then running at the same rate, occupancy never returns to zero — each gate
slot costs one full refresh, permanently (the ladder fits exactly: arrival ~3
slots -> 30+ ms, depth 2 -> 22-28, depth 1 -> 14). A bounded FIFO caps the
queue; nothing ever drains it. And depth 1 serializes presents on the on-glass
callback's delivery lag, so neither rung can approach the sub-refresh floor.
Stage-4 (PresentPacing.deadline) inverts drawable ownership instead:
- A CAMetalDisplayLink on its own runloop thread vends ONE deadline-timed
drawable per refresh (preferredFrameLatency 1) into a newest-wins LatestBox;
an unpresented vend is replaced by the next (back to the pool).
- The render thread pairs it with the newest decoded frame the moment either
half arrives — the common case presents a frame INSTANTLY into an already-
vended drawable, latching the upcoming refresh. No image queue can form and
nothing waits on on-glass callbacks (they only feed the meters now).
- A stashed drawable can lag a mid-session HDR reconfigure by one vend:
encodePresent skips the mismatched-format vend (frame re-rings) instead of
tripping Metal validation.
- iOS/iPadOS defaults to stage-4; tvOS keeps stage-3 until its own A/B
(PUNKTFUNK_PRESENTER=stage4); macOS resolves "stage4" back to its default
(the sync-off/DCP-panic saga — deadline pacing lands there deliberately or
not at all). Settings picker gains Stage 4 with the derived default marker.
- Gate depth defaults to 1 everywhere again; PUNKTFUNK_GATE_DEPTH stays only
to reproduce the standing-queue ladder on-device.
- PUNKTFUNK_PRESENT_DEBUG gains latchMs p50/max (present-issue -> on-glass:
standing queue reads ~n x period, healthy reads < 1 period) + noDrawable=.

Field report (iPad Pro 13" M4, 2752x2064@120): display 23.1 ms on the default
arrival pacing vs 14 ms glass-gated, dominating an otherwise ~14 ms pipeline.
On iOS the layer ALWAYS vsync-latches (displaySyncEnabled is macOS-only API)
and default-on VRR steers the panel to the stream rate, so arrival pacing's
sticky-FIFO saturation (~2-3 refreshes of queue) is the common case, not the
corner — the exact regime that made tvOS default to glass.
- PresenterChoice.platformDefault -> stage3 on iOS/iPadOS (joins tvOS);
explicit stage-2 stays the honest arrival A/B; macOS unchanged.
- PresentGate generalized to a capacity: depth 1 is bit-identical to before;
iOS runs depth 2 (one flip scanning out + one queued for the next latch),
so a decoded frame presents immediately and latches the very next vsync
instead of serializing on the previous flip's on-glass callback — expected
~5-8 ms at 120 Hz. tvOS keeps depth 1 (proven; A/B first), macOS is pinned
to 1 (glass there is the DCP swapID-panic mitigation — serialization is
its point). PUNKTFUNK_GATE_DEPTH (1-3) is the on-device A/B lever.
- Settings picker derives its "(default)" marker from presenterDefault
instead of hardcoding stage-2 as default / stage-3 as experimental.

Real-world PyroWave streaming maxed ~2.5 Gbps with sagging fps while raw
transport does 4.8. Root-caused to serial per-frame paths at BOTH ends
(the transport was never the limit); this fixes the two dominant ones.
Host (vendored shim, patch 0004): pyrowave_encoder_encode_gpu_synchronous
allocated four Vulkan buffers (meta + bitstream, Device + CachedHost) on
EVERY frame. At 240 fps with MB-scale bitstreams that per-frame allocator
churn stalled the encode itself. Pool them on the encoder and reuse across
frames (recreate only on a size grow); the sizes are session-fixed, so it
is pure reuse after frame 1. On an RTX 4090 the 5120x1440 submit+fence-wait
drops ~15 ms -> ~1 ms, i.e. the host serial ceiling goes 64 -> 1025 fps
(444+HDR 44 -> 614). Safe under the synchronous encode model; re-validated
by pyrowave_win_smoke (Windows) and pyrowave_smoke/_444 (Linux). Applies to
both host encoder paths (they share the shim).
Client (Apple Metal decoder): WaveletBitstream.parse reserved the payload
buffer per packet (reserveCapacity(count + words), an exact realloc each of
~3000 packets/frame => O(n²)) and copied word-by-word. Reserve once up
front and memcpy each packet's coefficients in one shot (all Apple
platforms are little-endian, so the wire's LE u32s land verbatim; memcpy is
alignment-free). 5.44 ms -> 0.055 ms per 1.44 MB frame (25x); byte-identical
(parser unit tests + golden-frame PSNR unchanged).
Also:
- native.rs: PUNKTFUNK_PYROWAVE_MAX_MBPS caps PyroWave's open-loop Automatic
bitrate pin for hosts on a constrained link (unset => no cap; an explicit
client rate bypasses it). The pin is all-intra + ABR-off, so at a high
pixel rate it can outrun the fabric (4:4:4+HDR 5120x1440@240 pins ~5.3
Gbps, over a 5 GbE link) and the overshoot just becomes loss.
- pf-encode caps(): report the real opened chroma instead of a hardcoded
4:2:0 default, so a genuine 4:4:4 session no longer trips the spurious
"encoder chroma disagrees with the negotiated Welcome" warn. Also fix a
latent Windows reset() that rebuilt at 4:2:0 for a 4:4:4 session.

Phases 4+5 of design/pyrowave-444-hdr.md. The Metal decoder needs NO new ABI:
every frame's sequence header carries chroma (444) and, since the Phase-3
stamps, the PQ/BT.2020 bits — so the decoder self-configures per session.
Decoder: WaveletLayout grows the 4:4:4 block space (chroma runs the full
pyramid like luma — no level-0 skip, no early half-res emit; the Metal
kernels were already chroma-agnostic, only the dispatch structure changes);
the parser accepts chroma_resolution=444, reads the PQ transfer bit, and
lifts the even-dims rule for 444; the plane ring allocates full-res chroma
and r16Unorm for PQ streams; CSC rows switch to depth-10 MSB-packed.
Presenter: planar HDR passthrough reuses pf_frag_planar on an rgba16Float
drawable (itur_2100_PQ + EDR metadata interpret the samples — same split as
pf_frag/pf_frag_hdr), plus a new pf_frag_planar_tm PQ->SDR tone-map (shared
pqToSdr tail refactored out of pf_frag_hdr_tv) for tvOS-without-headroom AND
macOS WINDOWED sessions, whose IOSurface present path (the DCP-panic
mitigation) is BGRA8-only. SessionModel stops stripping the HDR/10-bit/444
caps on the PyroWave opt-in.
New golden: au-dense444 + upstream's own 4:4:4 reference planes (regenerated
via the extended pyrowave_dump_golden); Metal decode matches at 64-67 dB
(420 fixtures re-verify 77-88 dB). Full Apple suite 157 tests green on a
real M-series GPU. Docs updated: the 8-bit-SDR-only wording is gone, the
Windows host is no longer 'on the roadmap', bpp scaling documented.

The DCP "mismatched swapID's" kernel panic reproduced on a 240 Hz Mac
Studio with stage-3 glass pacing active: a fully serialized,
one-in-flight present stream still races WindowServer's own swap
submissions. So the mitigation has to change the MECHANISM, not the
rate — the CAMetalLayer image queue itself is the racing path in a
composited (windowed) session.
Windowed PyroWave now presents the way video players do: the planar
CSC renders into a pooled IOSurface (4 × BGRA8, in-use-aware LRU
reuse) and the render thread hands it to a plain CALayer's `contents`
on main inside an ordinary CATransaction. WindowServer treats that as
normal layer damage on its own composite cadence — no out-of-band
image-queue swaps to race. Fullscreen keeps the CAMetalLayer path
(direct scanout, no compositing, no panic reports); the hosting view
pushes the window's composited state on every layout, and flipping
modes just covers/uncovers the metal layer (no black flash).
VT codecs keep the metal path everywhere: no panic reports there, and
their HDR/EDR presentation has no surface-contents equivalent wired.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Windowed PyroWave sessions were kernel-panicking Macs ("mismatched
swapID's" @UnifiedPipeline.cpp, WindowServer → AppleMobileDisp*-DCP).
The panic is an Apple DCP bug (SketchUp/Unity/240Hz-monitor reports hit
the same signature), but our stage-2 arrival pacing feeds the trigger
pattern: displaySyncEnabled=false out-of-band presents arriving faster
than the compositor latches them in a composited (windowed) session.
PyroWave makes that pattern routine — near-instant Metal wavelet decode
turns network clumps into same-millisecond present bursts, and it is
the codec that sustains stream rates above panel refresh.
Mitigation: PyroWave sessions on macOS now default to the stage-3
PresentGate (one presented-but-undisplayed swap in flight, serialized
on the on-glass callback, 100 ms stale backstop) — the racing pattern
cannot occur. Explicit stage2/stage3 picks (setting or
PUNKTFUNK_PRESENTER) still win, so the arrival-pacing A/B stays honest.
VideoToolbox codecs keep arrival pacing (decode latency spaces their
presents; no panic reports there).
PresenterChoice gains an `explicit` resolver (nil = no user selection)
so the codec-conditional default only applies when the user hasn't
picked a stage; pacing selection is a testable helper carrying the
rationale.

The W7/W8 client refactor (extracting FullscreenController/ApprovalRequest out of
ContentView, splitting Settings) landed the DefaultsKeys + scaffolding but dropped
the feature WIRING, which was uncommitted WIP shelved in a stash during the
16:28 clipboard/v4 reconcile. Recovered from that stash (+ its untracked-files
parent for the whole new ModifierLayout.swift) and re-ported onto the refactored
tree:
- invertScroll: applied in InputCapture.sendScroll (the one scroll sink) + Settings toggle
- modifierLayout (Cmd/Option switch): restored ModifierLayout.swift enum + KeyMaps
.applyModifierLayout + InputCapture.emitKey wire-boundary + Settings picker
- fullscreen shortcut (Ctrl+Cmd+F): InputCapture ⌃⌘F interception + onToggleFullscreen
+ StreamView wiring + Stream-menu item (the .punktfunkToggleFullscreen sink +
FullscreenController observer already survived on main)
- render scale: Settings picker + MatchWindowFollower renderScale/maxDimension
application + StreamView/StreamViewIOS plumbing (RenderScale.swift already on main)
StreamCommands re-ported by hand (the stash hunk deleted the since-landed clipboard
item — kept it, added the fullscreen item alongside). Recovered ModifierLayout +
RenderScale tests. swift build green; 15 tests pass.

Transcoding every image to PNG was the Phase-1 floor, but it bloats lossy
originals (a copied JPEG re-encoded lossless is 5-10x the bytes for zero
quality gain — feeding the render-timeout on constrained links) and flattens
GIFs to one frame. The wire already carries kind LISTS, so offer the original
format beside the portable fallback and let the destination pick:
- New wire kinds image/jpeg + image/gif (§3.5 extension; strings only, no
protocol change). image/png stays the universal floor every peer accepts.
- macOS: public.jpeg / com.compuserve.gif rows pass through verbatim both
directions; the PNG floor is announced whenever any image is present.
- Windows: registered JFIF/GIF formats read + promised verbatim; every image
offer still promises CF_DIB, whose delayed render now fetches the richest
offered kind (png > jpeg > gif) through the generalized image_to_dib.
- Linux maps gain the matching rows (native MIME pass-through).

macOS image copies rarely carry public.png — screenshots/Preview put TIFF on
the pasteboard, browsers add WebP/AVIF/GIF (observed live: TIFF+RTFD+WebP+AVIF+
8BPS+GIF, no PNG) — so the literal .png announce never fired and images
silently didn't sync. Announce image/png whenever a convertible image is
present (TIFF/HEIC alongside the native PNG check) and convert at serve time
via NSImage -> NSBitmapImageRep PNG (lazy, per design §3.5 — bytes still cross
only on a host paste).

this branch split quic/msgs.rs -> quic/{caps,control,...} and client.rs ->

- WorkerArgs.{clip_event_tx,clip_cmd_rx} -> client/worker.rs
- CLIP_EVENT_QUEUE -> client/planes.rs
- NativeClient clip fields, the 7 clip_* /
host_caps / next_clip methods, connect()
channel wiring -> client/mod.rs
- the control-task encode/decode arms and
the clipboard-task spawn -> client/pump.rs
Cargo.lock reconciled (adds pf-clipboard), punktfunk-host/Cargo.toml unions the W6
pf-* subsystem deps with pf-clipboard, and include/punktfunk_core.h is the cbindgen

repack, cancel-on-zero); Apple loses envelopeDeadline + sessionStaleSeconds + both tick
watchdogs (CoreHaptics realization untouched; mac xcframework rebuilt locally).
design/rumble-root-fix.md par. D. Engine 10/10 unit tests; core tests 176 Linux / 175
Windows + clippy -D warnings; swift build + RumbleTuningTests; Kotlin + android-native
compile green.

The NSPasteboard bridge completing Phase 1 (design/clipboard-and-file-transfer.md
§5) — with the host backends on this branch, copy/paste now crosses the wire in
both directions on macOS. Lazy in both directions:
- PunktfunkConnection grows the clipboard plane: its own clipboardLock (close()
joins it like the other pullers), hostCaps/hostSupportsClipboard from the
Welcome, the typed ClipEvent vocabulary, and the six ABI wrappers
(clipControl/clipOffer/clipFetch/clipServe/clipCancel/nextClipboard — borrowed
event payloads copied out before the next poll).
- ClipboardSync (PunktfunkKit, macOS-only): one drain thread bridging
NSPasteboard.general ↔ the QUIC clipboard plane. Local copies announce format
lists via a 500 ms changeCount poll (+ immediate on app activation); bytes
leave only on a host FetchRequest, answered from the live pasteboard and
seq-guarded against staleness. Host copies install one NSPasteboardItem whose
data provider fires only when a Mac app actually pastes, then blocks its
provider thread (never main) on a 10 s-bounded fetch. Concealed/Transient
pasteboards (password managers) are never announced; our own writes are
changeCount-suppressed (§3.4). Text/RTF/HTML/PNG; files ride Phase 2.
- UI: per-host "Share clipboard with this host" toggle (StoredHost.clipboardSync,
optional for saved-JSON forward-compat — wire-format tests extended), a
mid-session Share/Stop Sharing Clipboard item in the Stream menu (⌃⌥⇧C,
greyed without HOST_CAP_CLIPBOARD), SessionModel owning the lifecycle
(start on streaming after the trust gate, drain joined off-main on teardown).
swift build + swift test green (macOS). Requires the ABI v8 xcframework
(scripts/build-xcframework.sh).

Backgrounding a live session no longer freezes it when the user opts in: audio
keeps playing (UIBackgroundModes audio), the QUIC connection + pump stay live,
video decode is DROPPED, and a bounded timer auto-disconnects. Off by default.
- PunktfunkConnection.setVideoDropped/isVideoDropped: a tiny lock-guarded flag
both pumps read every iteration. StreamPump (stage-1), Stage2Pipeline (VT +
PyroWave) drain nextAU() for flow control but DISCARD the AU before any
VideoToolbox/Metal work — the crash/jetsam-safe seam (no GPU off-screen).
- SessionModel.enterBackground(timeoutMinutes:) / exitBackground(): set the drop
flag, mute the mic (privacy — SessionAudio.setMicMuted pauses the capture
engine), arm a DispatchSourceTimer that disconnect(deliberate:false)s on fire
(keeps host linger → fast late reconnect). exitBackground clears the flag and
requestKeyframe()s; the pump's freeze gate auto-arms on the resumed
frame-index gap so concealed frames are withheld until the IDR re-anchors.
disconnect() cancels the timer + clears isBackgrounded.
- ContentView scenePhase driver (iOS): .background+streaming+setting →
enterBackground; .active → exitBackground. scenePhase (not willResignActive)
so Control-Center/app-switcher peeks don't start the timer.
- Settings → General (iOS-only keepAliveSection): toggle + 1/5/10/30 timeout;
new keys backgroundKeepAlive (def off) / backgroundTimeoutMinutes (def 10).
- Info.plist: UIBackgroundModes [audio] + NSSupportsLiveActivities (for M3).
macOS swift build + swift test green (142 tests). The iOS-gated scenePhase
handler + settings section are not exercised by the macOS CI target (known §9
gap) — need on-glass verification (audio never gaps, video re-anchors <1s LAN,
timeout ends the session, phone-call audio-steal degrades gracefully).

Foundation milestone for Live Activities & Widgets (design/apple-live-
activities-and-widgets.md). No user-visible change beyond the URL scheme.
- New dependency-free PunktfunkShared SwiftPM target (+ library product) so a
future widget extension can link it WITHOUT PunktfunkKit (Rust staticlib +
presentation layer). Moves StoredHost (model + JSON codec), DefaultsKeys, and
punktfunkDefaultMgmtPort there; adds AppGroup.suiteName and the punktfunk://
DeepLink builder/parser. PunktfunkKit @_exported-imports it (no call-site
churn for consumers; intra-Kit files import it explicitly since imports are
file-scoped).
- HostStore reads/writes the shared App-Group suite (group.io.unom.punktfunk)
with a one-time migration from UserDefaults.standard (old value left in place
for staged rollout); reloads the "PunktfunkHosts" widget timeline on change.
- App Group entitlement on iOS/tvOS + macOS.
- CFBundleURLTypes scheme `punktfunk`; ContentView.onOpenURL routes
connect/<uuid>[?launch=<GameEntry.id>] into the existing connect() path
(unknown host / already-streaming guards; never tears down a live session).
- Round-trip tests: StoredHost JSON codec (+ legacy missing-optional decode),
DeepLink grammar. `swift build` + `swift test` green (142 tests, 0 failures).

Extends 56f9c8c4 (the Automatic-bitrate decode signal, core + Android) to the remaining
clients, so every platform caps Automatic at its real decoder limit instead of the network
link ceiling — the fix for a fast LAN feeding a slower hardware decoder.
- core/abi: punktfunk_connection_report_decode_us + _wants_decode_latency expose the
NativeClient methods to the C-ABI embedders (regenerated punktfunk_core.h, additive only).
- apple: PunktfunkConnection wrappers + Stage2Pipeline reports received→decoded from the
VideoToolbox decode-completion callback — every decoded frame, before the newest-wins ring
can drop the backlog. Stage-1 (AVSampleBufferDisplayLayer, no per-frame decode callback)
stays network-only; stage-2 is the metered path.
- windows/linux: the shared punktfunk-session client (pf-client-core) links core directly, so
it calls the NativeClient methods — report received→decoded from the pump, gated on
wants_decode_latency. Exact for the synchronous D3D11VA/software decode; received→submit
(still the decoder-input backpressure signal) for the async Vulkan-Video path.

The Apple client now decodes PyroWave natively on the presenter's own MTLDevice —
no MoltenVK, no upstream C++ in the app. Completes and wires up the decoder whose
early working-tree snapshot rode along in 9127c346:
- MetalWaveletShaders.swift: wavelet_dequant + idwt hand-ported from the vendored
GLSL (STORAGE_MODE 0 only; subgroup scans → 32-wide simdgroups; DCShift spec
constant → function constant; precision-1 split: fp16 levels 0-1 / fp32 2-4).
- MetalWaveletDecoder.swift: Swift reimplementation of push_packet/decode_packet
incl. the Phase-4 chunk-aligned window walk (FRAG chains, zeroed missing shards,
the >half-blocks partial rule), init_block_meta's block-index space, and the
42-dequant + 13-idwt dispatch structure with encoder-boundary barriers. SOF-dims
changes rebuild the size-dependent resources, which is also the mid-stream
resize path. Ring of 4 output plane sets on the presenter's queue.
- Presenter: pf_frag_planar (3xR8, the planar_csc.frag twin) + renderPlanar with
a shared present tail; ReadyFrame carries an image enum (.video | .planar).
- Stage2Pipeline: a dedicated PyroWave pump — no VideoToolbox machinery, no
keyframe/re-anchor recovery (all-intra; partials render as localized blur by
design), newest-frame-index staleness guard for late partials.
- Opt-in: "PyroWave (wired LAN)" codec entry (probe-gated, ≈A13 floor via a real
kernel-compile probe), selecting it advertises + prefers the codec and forces
the session SDR (HDR/10-bit/4:4:4 caps dropped, plan contract).
- Core ABI: punktfunk_connection_shard_payload() — the Welcome's negotiated shard
payload, needed by native decoders to walk chunk-aligned AUs.
- Validation: golden fixtures generated by the host encoder + upstream's own
decoder (pyrowave_dump_golden, RTX 5070 Ti); the Metal decode PSNR-matches at
77-88 dB across all planes for dense AND chunk-aligned AUs, and a hole-punched
partial still decodes. Parser unit tests cover the window walk, FRAG chains,
broken chains, the half-blocks gate, and the block-index layout.
Tests: apple 134 green (mac; iOS/tvOS build), host 312 w/ pyrowave on .21,
core 148 w/ quic; clippy/fmt clean.

- clients/apple: native Metal wavelet decoder + compute shaders (Phase 5),
decoding PyroWave without embedding MoltenVK.
- pf-client-core: plumb user_flags/completeness through Decoder::decode_frame
so the PyroWave backend parses chunk-aligned + partial AUs; gate the param's
unused-warning to exactly the non-pyrowave builds (fixes -D warnings on the
featureless Linux client build).
- punktfunk-host: on a mid-stream mode switch, re-resolve the "Automatic"
PyroWave bitrate for the new mode's ~1.6 bpp operating point (explicit rates
and H.26x ABR stay put); reject sub-128px PyroWave modes before the encoder
rebuild instead of after the ack.

The 2026 Steam Controller (Valve "Ibex" / SDL "Triton") captured on an
Android client is passed through AS-IS: the host presents a virtual pad
with the real wired identity (28DE:1302) and mirrors the physical pad's
raw HID reports, so Steam on the host drives it over hidraw exactly like
the real thing — trackpads, gyro, paddles, and its rumble/settings writes
flow back onto the physical controller. Protocol ground truth: SDL's
Valve-maintained SDL_hidapi_steam_triton.c + steam/controller_structs.h.
Core:
- GamepadPref::SteamController2 (wire byte 9; names steamcontroller2/
sc2/ibex) + PUNKTFUNK_GAMEPAD_STEAMCONTROLLER2 in the C ABI.
- Raw HID planes: RichInput::HidReport (0xCC/0x04, client→host input
reports verbatim, Copy fixed-64 body) and HidOutput::HidRaw (0xCD/0x05,
host→client feature/output writes for replay). Best-effort is sound by
the device protocol's own design (rumble re-sent every ~40 ms, settings
every ~3 s — losses self-heal); HidRaw bypasses hidout dedup for
exactly that reason.
Host (Linux):
- triton_proto.rs + steam_controller2.rs: Triton2Manager UHID backend —
no kernel driver binds the PID (hidraw only; Steam Input is the
consumer), raw mirroring with a typed-fallback 0x42 synthesizer until
the first raw report, SET_REPORT ack + raw forward, canned GET_REPORT
serial reply, rumble also parsed onto the universal 0xCA plane (phone
mirror). Rides the uhid + 28DE-conflict degrades; UHID promotion by
Steam is flagged in the creation log (usbip transport is the known
follow-up if Steam ignores Interface:-1 devices for Triton too).
Android:
- Sc2UsbLink (wired/Puck: vendor-interface claim detaches the OS driver,
interrupt read loop, lizard-off on the watchdog cadence, raw replay via
interrupt-OUT / SET_REPORT with hidapi report-id framing) and Sc2BleLink
(Valve vendor GATT service, notify subscribe machine, 0x45 re-framing,
HIGH connection priority).
- Sc2Capture orchestrator: raw plane + typed mirror (exit chord + host
degrade paths keep working) on a GamepadRouter external slot; raw
return path via GamepadFeedback.onHidRaw.
- nativeSendPadHidReport JNI (direct ByteBuffer, no per-report copy),
hidout raw decode, usb-host/BLUETOOTH_CONNECT manifest bits, opt-out
settings toggle, StreamScreen engagement incl. the USB permission flow.
Verified: core 149 + host 312 tests green on Linux (.21), on-box uhid
smoke creates/mirrors/tears down the virtual 28DE:1302, C ABI harness
round-trips, Android compileDebugKotlin green. On-glass with the real
controller owed.
