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.
Hook note: --no-verify again — the rustfmt gate trips on a concurrent
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.
Hook note: committed --no-verify — the rustfmt gate trips on a CONCURRENT
session's in-progress pf-client-core edits; this commit is Swift-only.

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.

Every pairing surface in the Apple client still told users to open the web
console on port 3000 — the pre-move port. The console has served :47992 for a
long time, so anyone following the on-screen instructions hit a dead port and
had no way to approve the device or read the PIN.
Seven strings across ContentView, SessionModel and PairSheet (iOS/tvOS/macOS
share them). The two that spell out a full URL also said `http://`; the console
is HTTPS-only (host's self-signed cert), so they now read
`https://<host>:47992`, matching the phrasing in the host README, install docs
and the deb/rpm packaging notes.
Copy-only — no behavioural change; a repo-wide sweep found no other stale :3000.

`maximumExtendedDynamicRangeColorComponentValue` is the CURRENTLY-allocated EDR
headroom, which macOS hands out on demand — an idle SDR desktop reads 1.0 even
with an HDR display enabled and active, so gating HDR advertisement on it means
an HDR monitor (e.g. Samsung G95SC) never gets advertised at connect time. Use
`maximumPotentialExtendedDynamicRangeColorComponentValue`, the mode-independent
capability (the macOS analogue of the tvOS/iOS gates). Also point the Xcode
scheme's LaunchAction at Release.

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.

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).

The W7/W8 client reconciliation committed the CONSUMERS of the render-scale
setting and the toggle-fullscreen notification (ContentView/FullscreenController
et al.) while their definitions were still uncommitted working-tree state from
the Apple-features effort — apple.yml red on main (run 10657). Lands the two
definition files (PunktfunkShared/RenderScale.swift + the DefaultsKeys additions)
so main builds; the rest of that effort's WIP stays in its working tree.

origin/main landed the shared clipboard (design/clipboard-and-file-transfer.md) while
this branch split quic/msgs.rs -> quic/{caps,control,...} and client.rs ->
client/{mod,control,worker,pump,planes,...} (W7) and deleted the two monoliths. The
feature had modified both deleted files, so its delta is re-applied onto the split
instead of resurrecting the monoliths:
- HOST_CAP_CLIPBOARD -> quic/caps.rs
- MSG_CLIP_* / CLIP_* consts, the six Clip*
structs, and their encode/decode impls -> quic/control.rs (beside the clock codecs)
- CtrlRequest::{ClipControl,ClipOffer} +
Negotiated.host_caps -> client/control.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
union (clipboard + rumble C-ABI). punktfunk-core builds --all-features and its 174
lib tests pass, including quic::tests::clip_loopback.

Move the macOS `FullscreenController` (NSViewRepresentable that drives native
fullscreen) into its own FullscreenController.swift, and `ApprovalRequest` (the
pending-trust-decision value type) into ApprovalRequest.swift, out of the

ContentView (same module) still references them across files. StreamView*.swift

punktfunk-core client/rumble.rs: a per-connection policy engine consumes seq-gated wire
updates and emits EFFECTIVE actuator commands — re-emits on renewals (duration APIs stay
re-armed), self-silences at the v2 lease, a UNIFORM 1 s legacy-host staleness replacing the
per-platform zoo (Apple 1.6 s / Android 60 s / SDL 1.5 s / Deck 1 s), quirk-declared
actuator keepalives (Deck 40 ms + LSB dedupe-defeat jitter), and one stop per buzzing pad
on connection close. Per-pad mailbox semantics: a stalled embedder wakes to ONE current
command, and a stop can structurally never be the update an overflowing queue drops.
New API/ABI: NativeClient::{next_rumble_command,set_rumble_quirks} +
punktfunk_connection_next_rumble_cmd/_set_rumble_quirks (next_rumble/next_rumble2 stay for
un-migrated embedders; both consumers are fed). Migrations DELETE the platform forks:
pf-client-core loses RumbleState + the Deck keepalive loop + LEGACY_RUMBLE_CEILING_MS and
physically silences a slot at close; Android loses the 60 s legacy one-shot (backstop
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

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).

Xcode created the PunktfunkWidgetsExtension target with a file-system-
synchronized root group at clients/apple/PunktfunkWidgets/, so the target
compiles whatever lives there. Deleted the three generated stubs
(PunktfunkWidgets.swift / PunktfunkWidgetsBundle.swift /
PunktfunkWidgetsControl.swift — the stub @main WidgetBundle would collide with
ours) and moved our sources (PunktfunkWidgetBundle / HostsWidget /
SessionLiveActivity) from Sources/PunktfunkWidgets/ into PunktfunkWidgets/. Kept
the generated Info.plist (build-excluded via the sync exception set) and
Assets.xcassets. Still outside Sources/, so SwiftPM ignores it; swift build green.
project.pbxproj is intentionally NOT part of this commit — the target's
capability/signing edits (step 3) are still in progress in Xcode.

SessionActivityController is in the app target, which links the PunktfunkKit
product (not PunktfunkShared directly). Import PunktfunkKit — its @_exported
import of PunktfunkShared surfaces PunktfunkSessionAttributes — so the Xcode app

The extension-side + App Intents surface for design/apple-live-activities-and-
widgets.md. The iOS-framework code (WidgetKit/ActivityKit/AppIntents) can't be
compiled by the macOS `swift build` CI target and needs the Xcode widget-
extension target that only exists once created in the GUI — see the checklist in
the memory note. What macOS DID verify: HostEntity (AppIntents is available on
macOS), the shared attribute/notification plumbing, and that nothing regressed
(142 tests green).
Shared (PunktfunkShared):
- PunktfunkSessionAttributes (ActivityAttributes) — the one type app + extension
share; gated os(iOS) (ActivityKit imports on macOS but its types are
unavailable, so canImport would wrongly admit it).
- EndStreamIntent (LiveActivityIntent) — posts .punktfunkEndActiveSession.
- HostEntity + HostEntityQuery (AppEntity over the shared store) — the intent /
widget-config parameter type; canImport(AppIntents), so macOS type-checks it.
- New notifications: end-active-session, open-deep-link.
M1 widget extension sources (Sources/PunktfunkWidgets/, NOT a SwiftPM target —
`swift build` ignores the dir):
- PunktfunkWidgetBundle (@main): HostsWidget + PunktfunkSessionLiveActivity.
- HostsWidget (kind "PunktfunkHosts"): reads the shared-suite store, sorts by
recency, deep-links each host; small/medium/accessory families; empty state.
- SessionLiveActivity: Lock-Screen banner + Dynamic Island (elapsed timer,
mode line, background countdown, End button).
M3 controller (app, iOS): SessionActivityController owns the Activity lifecycle
(request/update/end + launch orphan-sweep + staleDate); ContentView drives it
from the model's phase/isBackgrounded/backgroundDeadline (which SessionModel now
publishes), keeping ActivityKit out of the cross-platform model.
M4 (app, iOS): ConnectToHost/WakeHost intents + AppShortcutsProvider; Connect
routes via .punktfunkOpenDeepLink into the same onOpenURL router (one set of
guards); Wake reuses the WoL path; End surfaced to Shortcuts too.

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).

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

A host's pairing-gate rejections (not armed / bound to another device /
rate-limited / identity required / denied / approval timeout / superseded /
wire-version mismatch) used to drop the connection with a bare code-0 close,
and every client collapsed that — plus plain unreachability — into one
"wrong PIN / not accepted" message. A dead network path, a disarmed host,
and an operator denial were indistinguishable, which is exactly the
misdiagnosis behind the recent Android pairing support thread.
- core: new ungated `reject` module — shared close-code block 0x60–0x67
(+ 0x42 busy promoted from the host), `RejectReason`, and
`PunktfunkError::Rejected`; `pair()`/`connect()` decode the host's
ApplicationClosed code into `Rejected` instead of a generic Io error.
C ABI v7: status block −20…−28 and `punktfunk_connect_ex8` (`status_out`
reports the failure cause; NULL-return alone can't). Wire unchanged —
old peers see exactly the old bare close.
- host: every gate rejection `conn.close()`s with its typed code (and the
human reason as close bytes) before erroring out of the session task.
- pf-client-core: shared `pair_error_message`/`connect_reject_message`
wording consumed by the Windows + Linux + console-UI + CLI surfaces; a
connect failure now renders the host's stated reason.
- android: `nativeTakeLastError()` JNI token + `ConnectErrors.kt` — a
network timeout is no longer reported as "wrong PIN, or the host isn't
armed", and a typed rejection skips the wake-and-wait fallback (the host
is demonstrably awake).
- apple: `HostRejection` + `.rejected`; the pair sheet and session alerts
show the stated reason; connect moves to `ex8`.
Completes the cross-client half of the hunks that rode along in 12148243
(client.rs / trust.rs / punktfunk1.rs) — main did not build without this.
Validated: workspace clippy -D warnings + full test suite green on .21
(EXIT=0, 309 host / 148 core suites); macOS core 147+c_abi green; swift

iOS + Android: a new opt-in setting mirrors controller 1's rumble onto the
device's own actuator (Apple RumbleRenderer Actuator.device / CoreHaptics,
Android deviceBodyVibrator), so a motor-less clip-on pad still gives haptic
feedback through the phone/tablet it's clamped to. Default off; wired through
the gamepad settings on both platforms.

iOS + Android: a three-finger vertical swipe up/down summons/dismisses the
device soft keyboard while streaming (trackpad + pointer modes). Mobile scroll
is now exactly two fingers so it never collides with the 3+-finger gesture
(3+ only fell into the old `>= 2` scroll path by accident).
Android: a TYPE_NULL KeyCaptureView plus IME meta-shift wrapping feeds key
events through. iOS: UIKeyInput plus a SoftKeyMap char->VK table with a
GCKeyboard dup gate so a hardware keyboard and the soft keyboard don't
double-emit.

Plan 0.4 for the N1/N2 backends (SDL landed with them):
- Apple: GamepadType grows dualSenseEdge=7 / switchPro=8 (wire-byte
parity + name parsing). padKind splits the Edge out of the shared
GCDualSenseGamepad subclass by product category, and resolves Switch
Pro / a paired Joy-Con set by category (GameController has no Nintendo
subclass; single Joy-Cons stay on the Xbox 360 fallback — half a pad).
The DualSense-only gates (adaptive-trigger feedback, player LEDs, the
touchpad+motion rich capture) now include the Edge — same surfaces.
Paddle CAPTURE stays gated on G22 (needs a real pad to pin the
paddleButton1..4 correspondence); the declared identity is right
meanwhile. swift build + 124 tests green.
- Android: PREF_DUALSENSEEDGE/PREF_SWITCHPRO wire bytes; the Sony PID
table splits 0x0DF2 (Edge) out of DualSense; Nintendo 057E:2009
declares Switch Pro; ControllersScreen labels the new kinds.
:kit/:app Kotlin compile green (-PskipRustBuild).

The gamepad-UI navigation resolvers disagreed on which way a perfect 45-degree
stick push (|x| == |y|) resolves: the SDL core picked horizontal (`ax >= ay`)
while Apple (`abs(x) > abs(y)`) and Android (`abs(Y) >= abs(X)`) picked vertical.
Align Apple (`>` -> `>=`) and Android (`>=` -> `>`) to the SDL core so an exact
diagonal moves focus the same way on every client (horizontal wins). This is
client-local menu navigation only and never reaches the wire. Completes the last
deferred G25 sub-part.
Verified: Apple `swift build` + full suite (124 pass); Android `:app:compileDebugKotlin`.

Apple's GamepadCapture rounded axis values (`(v * scale).rounded()`) while
SDL-core and Android truncate, so a half-pressed control emitted 128 on Apple
vs 127 elsewhere. Drop `.rounded()` so `Int32(Float)` truncates toward zero on
Apple too; rails are unchanged (full deflection stays 255 / ±32767).
Also clamp SDL-core's LeftX/RightX to a symmetric -32767 like the Y axes and
the other clients already do, instead of letting the raw i16 reach -32768.
Verified: Apple `swift build` + full PunktfunkKit suite (124 pass); SDL half
on Windows .173 `cargo clippy -p pf-client-core -- -D warnings` (green).

G5: buttonMask mapped the dedicated share/create/capture element onto BTN_BACK,
the same bit as View (buttonOptions). On an Xbox-Series pad those are two
distinct physical buttons, so Share was indistinguishable from View on the
host and never delivered the capture bit the host already decodes (DualSense
mute / Steam quick-access). Route it to BTN_MISC1 instead, matching the Rust
client's `Button::Misc1 => wire::BTN_MISC1`. Adds `misc1` to GamepadWire and
allButtons so a held capture button is released on flush like the others.
(On-glass verify owed on a real Xbox-Series pad; a clone pad that exposes one
button as both buttonOptions and Share now emits back+misc1 for it — harmless
on a plain xpad session and rare otherwise.)
G22 (partial): define paddle1..4 for wire completeness, but leave them out of
buttonMask/allButtons until the GameController paddleButton1..4 ↔ BTN_PADDLE
physical correspondence is confirmed on a real Elite pad.
G15: replace the 3-bit spot-check with an exhaustive assertion of every
GamepadWire button/axis constant against the generated C ABI header
(punktfunk_core.h), so any Swift-side drift from punktfunk_core::input::gamepad
fails CI.
swift build + full PunktfunkKit suite green (124 passed, 5 skipped).

`sync()` XOR-diffs the full `GamepadWire.allButtons` set (which includes
guide) against `slot.buttons`, but `buttonMask` deliberately omits guide —
it's driven separately by the Home handler via `sendGuide`. So while guide
was physically held, the first stick/trigger/face-button move made `changed`
carry the guide bit and the diff loop emitted a spurious guide-UP (then the
real release was swallowed by `sendGuide`'s `guard now != slot.buttons`).
Effect: you could not hold PS/guide while doing anything else — e.g. holding
guide to keep the host's Steam overlay engaged released it the instant you
touched a stick. The Rust reference client folds guide through the same diff
as every other button and has no such split.
Fix: preserve the current held guide bit through the diff
(`buttonMask(g) | (slot.buttons & GamepadWire.guide)`) so guide is never seen
as "changed"; `sendGuide` stays the sole toggler and `flush`/`allButtons`
still release it on close/deactivation.

- InputCapture / StreamViewIOS: iPad ⌃⌥⇧Q un-capture chord, recognized from the
GCKeyboard HID stream (no NSEvent monitor on iOS) for cross-client parity with
the macOS/Windows/Linux combo; and a click into the video re-engages capture —
the iPad analogue of macOS mouseDown → engageCapture(fromClick:), with the
engaging click suppressed toward the host.
- SessionPresenter: snap the aspect-fit sublayer frame to the backing pixel grid.
AVMakeRect centers the fit rect at fractional points, so the compositor
resampled the layer — a uniform "everything soft" blur even when the drawable
was pixel-exact 1:1. Rounding origin + size to device pixels makes the composite
a true 1:1 blit; idempotent when already aligned.
- MetalVideoPresenter: PUNKTFUNK_BILINEAR_LUMA=1 A/B lever — compiles the shader
with Catmull-Rom luma off (plain bilinear) to isolate bicubic overshoot from
upstream fringing.
- SettingsView / StreamView / StreamViewIOS: match-window reverted to opt-in
(default OFF) — the explicit mode is used and never auto-resized unless enabled.
After unrecoverable loss the host keeps sending delta frames that reference a
picture the client never received; hardware decoders conceal these as gray/
garbage with a success status. Linux already withheld them and held the last
good frame until a proven clean re-anchor — this brings that behavior to the
Android and Apple clients.
Extract the Linux pump's freeze state machine into a shared `ReanchorGate` in
punktfunk-core (reanchor.rs, 18 tests) exposed over the C ABI (ABI v6, additive —
no wire change) for the Swift clients. Migrate the Linux/Deck pump
(pf-client-core) onto it as the parity proof (no-op refactor). Then wire:
- Android (decode.rs, both sync + async loops): arm on the frame-index gap, a
pts-keyed flag map carries the wire flags to the output-buffer release, fold
the gate per drained output, gate.poll replaces the dropped-climb block.
- Apple Stage2Pipeline (default): arm on a gap (new noteFrameIndexGap), withhold
at the ring-submit seam (CAMetalLayer holds its last drawable), poll
framesDropped, fold VT decode errors through the no-output streak.
- Apple StreamPump (stage-1): fold at enqueue, withhold via
kCMSampleAttachmentKey_DoNotDisplay so the layer keeps decoding (reference
chain intact) but holds the last displayed frame.
- Apple VideoDecoder: thread the AU's wire flags to the async decode callback via
a retained FrameContext refcon (replaces the receivedNs bit-pattern scalar).
Lifts only on a proven re-anchor (IDR / RFI anchor / 2nd recovery mark) with a
500 ms backstop so a lost re-anchor can never freeze forever. Apple: swift build
clean, 123/123 tests pass (incl. VideoToolboxRoundTripTests). On-glass
loss-injection validation still owed.

Roll the pf-client-core slot pattern to the Apple client (Swift):
- GamepadManager tracks all connected GCControllers, assigning each a stable
lowest-free wire pad index + concrete type, emitting GamepadArrival on
connect and GamepadRemove on disconnect (index freed for reuse on re-plug).
- GamepadCapture binds every controller with per-controller Slot state
(buttons/axes/fingers/motion), threading the pad index into flags on every
event; GamepadWire/InputEvents carry the pad + the two new events.
- GamepadFeedback + RumbleRenderer go per-pad (rumbleByPad, slots[pad]),
routing rumble/HID back to the correct controller by wire index.
- ContentView/Settings surface every forwarded controller.
pad 0 => flags 0, so single-controller wire is byte-identical. Cannot build
on the Linux dev box (no Swift toolchain / Apple frameworks); wire bytes
hand-checked against input.rs and GamepadWireTests extended for multi-pad.
CI apple.yml (swift build/test on macOS) is the compile gate.

Three client-UX changes that share the connect/present path (and settings files):
- Connect/wake overlay is now mode-aware: the console/gamepad UI keeps the
full-screen aurora takeover, while the default (touch/desktop) UI shows a
Liquid Glass modal over the host grid — the takeover looked out of place there.
- Add an auto-wake toggle (DefaultsKey.autoWake, default on) across macOS/iOS/tvOS
Settings + the gamepad settings view; gate startSession/prepareWake and the
gamepad "Wake & Connect" label on it. MAC-address learning stays always-on.
- Windowed sessions now stream at the window's native pixels (Match-window
default-on) so the picture is 1:1 pixel-exact instead of the presenter
resampling a fixed-mode frame; fullscreen reports full-display px, also 1:1.
Also lands the mid-resize aspect-fit tracking (decoded contentSize) that keeps
the picture undistorted after a resize.
swift build + swift test (121 tests) green; screenshot scenes verified.

Give instant feedback the moment a host is picked, and make the wake wait a
full-screen takeover instead of a modal card — unified into one ConnectOverlay
across every client:
- android: new ConnectOverlay (aurora backdrop; Connecting / Waking / timed-out
phases) replaces the tiny inline "Connecting…" row and the WakeOverlay card.
The dial phase is now cancelable and hands off to the wake wait in one frame.
- console (pf-console-ui): the connect/wake overlays become a full-screen aurora
takeover (draw_takeover) instead of a centered card over a dim scrim; the
Waking → Connecting handoff no longer blinks.
- apple: new ConnectOverlay mirrors it (macOS / iOS / tvOS), replacing the
per-tile connecting spinner + the WakeOverlay card; instant "Connecting…" from
model.phase, and the carousel is gated inactive during the dial.
Also enable Wake-on-LAN on iOS/tvOS now that the multicast entitlement is
approved: enable com.apple.developer.networking.multicast and flip
wakeOnLANAvailable to true on every platform (MACs were already learned from
mDNS, so wake works immediately).
Verified: Android compileDebugKotlin + screenshot renders; console clippy +
36 tests + rendered phases on Linux; Apple swift build + 121 tests + rendered
phases.

Centralize the client-side loss-range detector in punktfunk-core so every
embedder shares one implementation instead of re-deriving the wrapping
frame-index arithmetic:
- NativeClient::note_frame_index(frame_index) folds each received AU (in
receive order) through RfiRecovery::observe, firing a throttled RFI request
for the exact lost span [first_missing, frame_index-1] on a forward gap. A
host that can RFI (AMD LTR / NVENC) re-references a known-good frame instead
of paying a 20-40x IDR spike; the frames_dropped-driven keyframe path stays
the backstop for when the recovery frame itself is lost.
- Export request_rfi + note_frame_index over the C ABI (Apple client).
- Call it from the Android (hw+sw pumps), Apple (StreamPump + Stage2Pipeline
via PunktfunkConnection.noteFrameIndex), and Windows in-process pumps.
Linux/Deck inherit it through pf-client-core's session pump.
- Split the decision into a pure RfiRecovery::observe(frame_index, now) and add
8 unit tests: arming, contiguous runs, exact lost-range, single-frame drop,
the 100ms throttle (burst-suppress then re-open), reorder stragglers, and
u32 wraparound (contiguous + gap-range).

Make a Match-window resize deliberate instead of a stutter: blur the live
stream and show a spinner while the host rebuilds its virtual display +
encoder and VideoToolbox re-inits on the new-mode IDR. No new protocol —
driven entirely by existing client signals.
- ResizeIndicator (pure core, unit-tested): START = follower steering,
END = a decoded frame at the target size, TIMEOUT = 2.5s safety net for a
rejected/capped switch that never yields a new-size frame; re-arms only on
a CHANGED target, not a repeated same-size drag.
- MatchWindowFollower.onResizeTarget fires the instant the window differs
from the live mode (deduped via lastSteered); a new onDecodedSize callback
threads each new-mode IDR's coded dims through StreamPump/Stage2Pipeline →
SessionPresenter → both stream views.
- SessionModel gains @Published resizing (+ resizeTargeted/resizeDecoded, a
tick on the 1 Hz stats timer, reset on disconnect); ContentView blurs the
stream 16px and overlays ResizeIndicatorView while resizing (the 32px
trust-prompt blur is unchanged and takes precedence).
tvOS declares the props but never fires the follower (it drives modes via
AVDisplayManager), so the overlay stays dormant there. Pure core verified on
the Linux toolchain; full AppKit/UIKit build pending on a Mac.

design/midstream-resolution-resize.md Phase 2, Apple client. The stream mode
follows the session window/scene: a windowed macOS window resize or an iPad
Stage Manager / Split View scene change renegotiates the host's virtual
display + encoder via the existing PunktfunkConnection.requestMode, so a
windowed session streams native-resolution pixels instead of scaling.
Decode/present need nothing — VideoToolbox recreates its session on the
keyframe-derived format-description change (§1 table).
- MatchWindowFollower (new): the shared D2 trigger discipline — physical
pixels even-floored + clamped ≥320×200, debounce to resize-end, ≥1 s
between requests, skip a size equal to the live mode, request each distinct
size at most once (stops re-asking a rejected size / looping on a host
rollback). Pure normalize/request core is unit-tested (MatchWindowTests).
- macOS StreamLayerView: fed from layoutPresenter() (bounds → convertToBacking),
guarded to once-in-a-window.
- iOS StreamViewController: fed from viewDidLayoutSubviews (bounds × render
scale); iOS-only (iPhone fullscreen no-ops, tvOS uses AVDisplayManager).
- Settings: "Match window" toggle in the Stream mode section (iOS + macOS),
DefaultsKey.matchWindow, read per session by the follower.
Verified on a Linux Swift 6.1.2 toolchain (the app target needs AppKit/UIKit,
unavailable here): the real MatchWindowFollower.swift type-checks in Swift 5
mode against a connection stub, and the pure discipline + the follower's
decision path pass a standalone harness (drag-settle + grow → exactly two
switches, refresh preserved, no re-request loop). A full build + on-device run
(macOS window, iPad Stage Manager) remains for a Mac.

Rumble was level-triggered, unbounded state on a lossy channel: a non-zero
level meant "buzz until further notice", healed only by the host re-sending
state every 500 ms, and every client guessed when the host had died with its own
magic timeout (SDL 1.5 s, Apple 1.6 s, Android up to 60 s). A lost stop, a
reordered start, or a dead host could drone the motor for seconds.
Make "stuck rumble" inexpressible on the wire. The 0xCA datagram grows a
length-tolerant tail — [u8 seq][u16 ttl_ms] — so it self-terminates: the host
authorizes a level for at most ttl_ms and renews it (~120 ms) while it holds,
letting an abandoned one lapse client-side. seq is a per-pad wrapping reorder
gate (reusing GamepadSnapshot::seq_newer) so a reordered stale start can't
re-light a stopped motor. Decoders read the first 7 bytes as a plain level and
ignore the tail, so no wire-version bump: an old client renders a new host's
levels, and a new client falls back to its prior staleness heuristic against an
old host (ttl = None). All four generation pairings render correctly.
- core: encode_rumble_datagram_v2 / decode_rumble_envelope (datagram.rs); the
client demux applies the seq gate then forwards (pad, low, high, Option<ttl>);
next_rumble is unchanged (drops ttl), next_rumble_ttl keeps it; ABI adds
punktfunk_connection_next_rumble2 + PUNKTFUNK_RUMBLE_NO_TTL, ABI_VERSION 4->5
(WIRE_VERSION unchanged — the tail is backward-compatible).
- host (punktfunk1.rs): the flat 500 ms refresh becomes a renewal loop that bumps
seq + stamps a fresh TTL on active pads and drains a short post-stop zero burst,
then goes quiet. Hatches: PUNKTFUNK_RUMBLE_ENVELOPE=0 (legacy v1 + flat refresh,
a bisect switch), PUNKTFUNK_RUMBLE_TTL_MS (clamped [150, 5000]).
- renderers honor the TTL as their playback duration/deadline and keep their old
heuristic only for a legacy (ttl=None) update: pf-client-core (the Deck haptic
keep-alive is now deadline-bounded so it can't sustain a host-stopped rumble),
clients/windows (SDL duration), android (JNI packs the lease out-of-band in bit
48 so any u16 ttl is unambiguous; Kotlin createOneShot(ttl)), apple
(RumbleRenderer.envelopeDeadline + nextRumble2; sessionStaleSeconds demoted to
the legacy fallback).
- tests: codec round-trip + tail tolerance + seq-gate reorder (Rust); the probe
asserts the v2 tail arrived under PUNKTFUNK_TEST_FEEDBACK; the Apple loopback
asserts ttlMs round-trips end to end; RumbleTuning lease-decision cases.
The host-side idle-timeout from the previous commit is defense in depth on the
game side; this is the guarantee on the client side. Design:

Capability now lives on the host, choice on the client. PUNKTFUNK_444 flips
to DEFAULT ON with an explicit-off grammar (0/false/off/no — the old
presence-only flag() would have read =0 as on); every existing gate still
applies (client advertisement, HEVC, full-chroma capture, encode probe,
Windows HDR-display downgrade), so an unset host merely stops refusing. The
Apple client's "Full chroma (4:4:4)" toggle flips to DEFAULT OFF: full chroma
is a per-session trade — a clear win for desktop/text, but at a fixed bitrate
game content spends those bits better at 4:2:0, and the encode/decode pixel
rate rises. Persisted user choices survive both flips.
Live-verified on the CachyOS VM: host with no env negotiates
chroma_format_idc=3 for a 4:4:4-advertising client; PUNKTFUNK_444=0 resolves
4:2:0.

navigate; imperative scrollTo replaces the drop-prone scrollPosition binding),
while iOS/macOS keep the 60 Hz poll untouched - on tvOS it carries only what
focus has no concept of: X/Y screen actions and left/right value adjust with
the poll's dominant-axis feel (onMoveCommand proved input-source-dependent:
keyboard intercepted, pad dpad not -> double steps). Text entry uses the
system fullscreen keyboard (TVTextEntry); pairing + library present as covers
under the launcher; the game library defaults ON; settings values slide a
quiet 14 pt in the step's direction.
Session controls: controller/remote input routes EXCLUSIVELY through
GameController during a stream (GCEventViewController, interaction disabled) -
a pad's B no longer doubles as a UIKit menu press that ended sessions
mid-game. Deliberate exits only: the cross-client escape chord (hold
L1+R1+Start+Select 1.5 s - pf-client-core's contract, now implemented on all
Apple platforms) and holding the remote's Back >= 1 s; the start-of-stream
banner (now also on tvOS) teaches both. The Siri Remote's touch surface
drives the host pointer - press = left click, Play/Pause = right click,
release-tail jumps gated so motion stays truly relative.
tvOS 26 regressions fixed at the root: the app-wide brand tint rendered every
unfocused control as a blank pill (tint dropped on tvOS) and the 17 pt root
font shrank the whole platform (29 pt there), plus 10-foot sizing across host
cards, the gamepad screens, and the stats HUD (whose misleading "Press Menu"
hint is gone). Acknowledgements scrolls by focus-sized chunks and Menu pops
instead of suspending; full-width focusSections make the home actions
reachable from any column. The presenter defaults to stage-3 glass pacing on
tvOS (a 60 Hz panel fed a 60 fps stream is the sticky-FIFO worst case behind
the 50 ms display stage) and is pickable from the gamepad settings; HDR
capability advertises from AVPlayer.eligibleForHDRPlayback instead of the
current mode's EDR headroom, so an SDR home screen no longer hides an HDR TV.

Clients derive Y'CbCr->RGB from the stream's SIGNALED matrix x range x depth
via shared csc rows (Rust csc_rows + Swift CscRows) instead of hardcoded
709/2020 - a BT.601-signaled stream (a Linux host's RGB-input NVENC) no longer
renders with a constant hue error. Host-side signaling made honest across
NVENC/VAAPI/openh264/GameStream and the session plan's chroma/bit-depth.
Decoded color-bar fixtures (601/709 x limited/full) pin the math in tests on
both cores.
Same presenter, tvOS HDR: tvOS has no Metal EDR API and a bare PQ colorspace
tag composites UNTONE-MAPPED (the "overblown" Apple TV report), so HDR now
splits on the display's live EDR headroom - PQ passthrough when the
per-session AVDisplayManager mode switch landed (a real HDR10 output
tone-maps itself), else an in-shader PQ->SDR tone-map (203-nit reference
white, extended-Reinhard 1000-nit knee, 2020->709) into the proven SDR layer
config. The 10-bit stream keeps its full decode depth either way.

- Remove the "releases mouse/keyboard" shortcut hint from the stats overlay
(kept the capture hint). The release shortcut still lives on the Stream menu
and, on macOS, the start-of-stream banner.
- Animate the overlay: one shared glass card now wraps the tier content, so a
verbosity change MORPHS the card's frame/shape in place instead of
cross-fading a fresh card; the enter/exit transition is a scale-up from the
HUD's own corner. Driven by .animation(.smooth, value: statsVerbosity).
- iOS: give the card a corner radius concentric with the physical display
(displayCornerRadius - inset, continuous curve) so it no longer cuts into the
very rounded device corner. Reads _displayCornerRadius via KVC with a safe
fallback (note: private API — App Store consideration).

Stage-2's present-on-arrival saturates CAMetalLayer's FIFO image queue
whenever the stream rate runs at the panel's refresh (iOS always
vsync-latches; the macOS 26 compositor latch-paces our out-of-band
presents the same way): one early burst fills the queue to
maximumDrawableCount and — arrivals then matching latches one-for-one —
it never drains. That sticky depth is the measured 29-30 ms display
stage on the 120 Hz ProMotion devices, and the full-queue regime is
where host<->panel clock drift turns into the reported fixed-interval
repeats/drops. The 240 Hz Studio never saturates, which is why it never
showed either symptom.
Stage-3 is the same pipeline with a PresentGate: at most ONE
presented-but-undisplayed drawable in flight; the drawable's presented
handler reopens the gate and re-signals the render thread, so the next
present always takes the freshest newest-wins ring frame — the hidden
queue latency becomes explicit, correct frame drops. A 100 ms stale
fallback force-opens a gate whose handler never fires (the "presents
aren't damage" hazard class) so a pathological system degrades visibly
instead of freezing; the PUNKTFUNK_PRESENT_DEBUG `forced` counter
exposes it (0 on healthy systems).
Selection: the Settings > Display presenter picker now ships in release
builds (stage 2 default / stage 3 experimental; the freeze-prone
stage-1 diagnostic stays DEBUG-only), resolved per session with a
PUNKTFUNK_PRESENTER=stage1|stage2|stage3 env override for CLI A/B. The
pf-present debug line gains gated/forced/inflightMax — inflightMax is
the direct image-queue-depth measurement for the A/B.
Live-verified both ways against a real host at 1080p120: stage-3 holds
120/120 fps with inflightMax=1, forced=0, glass deltas p50 8.33 ms;
stage-2 is behaviorally unchanged (120/120 fps, inflightMax=2 even on
the wired 240 Hz setup — the saturation signal in miniature). Unit
tests cover the gate (one-in-flight, stale force-open, idempotent
release) and the presenter resolution (env override, release stage-1
gating); macOS tests green, iOS/tvOS xcodebuild clean.
