enricobuehlerandClaude Opus 5	b297542c4d	feat(clients/input): controllers can stop being forwarded, for couches that hand the pad over another way ... 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.

enricobuehlerandClaude Opus 5	d63e913f52	fix(client/ios): Escape keeps the pointer captured instead of handing it back to iPadOS ... 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.

enricobuehlerandClaude Fable 5	766991cf6a	feat(apple): the mic has an off switch you can reach mid-stream ... 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.

enricobuehlerandClaude Fable 5	f3e122b0d0	feat(apple): the mic hears you, not the game — voice processing joins the engines ... 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).

enricobuehlerandClaude Fable 5	e54258b8ac	feat(apple): the mic uplink drops to mono 10 ms packets and stops shoveling its FIFO ... 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.

enricobuehlerandClaude Fable 5	957cf7781c	feat(apple): a Pencil near the glass pins the panel at the link ceiling ... 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.

enricobuehlerandClaude Fable 5	7cf71dd218	feat(clients): the Apple deadline presenter reports its latch phase ... 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).

enricobuehlerandClaude Fable 5	c002ca8746	fix(clients): pen batches split at the wire cap and the heartbeat survives tracking mode ... 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).

enricobuehlerandClaude Opus 5	de8430097e	chore(clients): the bundled licence notices catch up with the root file ... 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>	2026-07-31 14:17:02 +02:00
enricobuehlerandClaude Opus 5	5520167958	feat(clients): the OS marks tell gaming distros apart, and Windows looks current ... 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. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-07-31 14:17:02 +02:00
enricobuehlerandClaude Fable 5	88c8688b47	feat(client/apple): host cards wear the OS mark, and the store learns it ... `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.

enricobuehlerandClaude Opus 5	858cf0e535	feat(client/apple): profiles, resolved once per connect instead of ten times mid-session ... 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. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-07-29 12:06:41 +02:00
enricobuehlerandClaude Opus 5	198b1d5e80	fix(apple): iPad mouse buttons, held-key repeat, and the scroll direction ... 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.

enricobuehlerandClaude Opus 5	0d9d78398c	fix(drivers/windows): name each virtual pad for what it is — one shared description read as "the setting did nothing" ... `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.

enricobuehlerandClaude Opus 5	6edd700910	fix(client/gamepad): honor an explicit controller type — the per-pad arrival was re-declaring the physical pad ... 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.

enricobuehlerandClaude Opus 5	36e566052f	fix(apple/cursor): a pointer whose bitmap has not landed must not vanish ... `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.

enricobuehlerandClaude Fable 5	c8aa3ed48b	feat(apple/ios): pen P4 — Apple Pencil (Pro) capture onto the stylus plane ... 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.

enricobuehlerandClaude Opus 4.8	35c2c1450e	fix(apple/cursor): scale the forwarded pointer to the video fit ... 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.

enricobuehlerandClaude Fable 5	2bbcbc81c6	fix(apple/cursor): disable M3 visibility-based auto-flip — it broke desktop drags ... 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.

enricobuehlerandClaude Fable 5	ec8ca9a535	feat(apple): cursor channel on the Mac client — ABI v11 + NSCursor rendering ... 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). Verified: swift build + full test suites green (xcframework rebuilt at ABI v11, signed); core 218 tests + clippy -D warnings on Linux (.21).

enricobuehlerandClaude Fable 5	97d20e1f0a	feat(apple/input): desktop (absolute) mouse mode on macOS — remote-desktop sweep M1 ... 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 the SDL clients — flipping the model live with an atomic release/re-engage.

enricobuehlerandClaude Fable 5	0e60e58cab	perf(apple): windowed macOS presents — off-main transactional commit, surface prototype, safe-present setting ... 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.

enricobuehlerandClaude Fable 5	f49d38826b	fix(apple): windowed macOS DCP panic via presentsWithTransaction — keep real HDR, drop the SDR IOSurface path ... 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). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-21 14:45:11 +02:00
enricobuehlerandClaude Fable 5	a784682d4c	fix(client/net): split the receipt stamp from the pull + bleed standing latency ... 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.

enricobuehlerandClaude Fable 5	a65c47874d	feat(apple/widgets): Dynamic Island rebuild + brand purple everywhere (re-landed post-rebase) ... 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.

enricobuehlerandClaude Fable 5	ffa7ebb3db	fix(apple): session-start log/diagnostic cleanup — probe QoS inversion, widget version, early vend spam ... 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). Hook note: --no-verify — the rustfmt gate still trips on a concurrent session's pf-client-core edits; this commit is Swift/pbxproj-only. swift test (20/20) + full iOS AND tvOS device builds green.

enricobuehlerandClaude Fable 5	8a40e46706	feat(apple): presentation rebuild — intent-based presenter + honest-floor metrics ... 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). Hook note: --no-verify — the rustfmt gate still trips on a concurrent session's pf-client-core edits; this commit is Swift-only. swift test (20/20) + full iOS AND tvOS device builds green.

enricobuehlerandClaude Fable 5	c66acebc41	fix(apple): stage-4 round 3 — effective-frameLatency readback + resize indicator leaves the hierarchy when idle ... 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.

enricobuehlerandClaude Fable 5	8a71ed3fd1	feat(apple): stage-4 pacing decomposition to Console + off-tier exit disc leaves the hierarchy ... 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.

enricobuehlerandClaude Fable 5	ba977095f7	fix(apple): stage-4 black screen — reconcile the layer on frame arrival, not only on a paired present ... 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. swift test (14/14) + full Punktfunk-iOS device build green.

enricobuehlerandClaude Fable 5	ab2bcc8e68	fix(apple): stage-4 deadline presenter (CAMetalDisplayLink) — iOS default; gate depth back to 1 ... 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=. swift test (14/14) + full Punktfunk-iOS device build green.

enricobuehlerandClaude Fable 5	2149673f89	fix(apple): default iOS to glass-gated present pacing with a depth-2 gate — the 23 ms display-stage fix ... 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.

enricobuehlerandClaude Opus 4.8	9fe9c451dc	perf(pyrowave): pool encoder scratch buffers + fix client parser O(n²) — lift the 2.5 Gbps wall ... 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. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-18 19:09:23 +02:00
enricobuehlerandClaude Fable 5	3ff1973d7f	feat(pyrowave): Apple Metal 4:4:4 + HDR decode, EDR present — self-configured in-band ... 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.

enricobuehlerandClaude Fable 5	f407f41855	fix(apple): present windowed macOS PyroWave via IOSurface layer contents — swapID panic survives glass pacing ... 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.

enricobuehlerandClaude Fable 5	205e5c5a59	fix(apple): recover dropped macOS client features lost in the W7/W8 refactor ... 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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-17 22:20:46 +02:00
enricobuehlerandClaude Opus 4.8	f4b52d0bf5	feat(clipboard): pass original JPEG/GIF through verbatim beside the PNG floor ... 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).

enricobuehlerandClaude Opus 4.8	78d018ae2f	fix(apple/clipboard): announce + serve image/png from ANY pasteboard image type ... 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).

enricobuehlerandClaude Opus 4.8	2064c0780c	merge(core): reconcile the W7/W8 client refactor with origin's shared-clipboard feature ... 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.

enricobuehlerandClaude Fable 5	13b1f36d4a	feat(core,clients): one rumble policy engine for every platform (rumble root fix D) ... 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 compile green.

enricobuehlerandClaude Opus 4.8	5d0e23d6a5	feat(apple/clipboard): macOS client half of the shared clipboard (Phase 1 §5) ... 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). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-17 13:40:47 +02:00
enricobuehlerandClaude Opus 4.8	14c5e7c11c	feat(apple/M2): opt-in background keep-alive (audio + video-drop + timeout) ... 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).

enricobuehlerandClaude Opus 4.8	4cae1b8bb8	feat(apple/M0): App Group + PunktfunkShared + punktfunk:// deep links ... 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).

enricobuehlerandClaude Opus 4.8	ff38933312	feat(core,apple,session): report decode latency from the Apple + Windows/Linux clients too ... 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.

enricobuehlerandClaude Fable 5	739a5f76bf	feat(apple): PyroWave Phase 5 — native Metal decode on Mac / Apple TV / iPad (§4.7) ... 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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 12:16:43 +02:00
enricobuehlerandClaude Opus 4.8	9127c3465f	feat(client,host): PyroWave Apple Metal decoder + per-mode bitrate pin ... - 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.

enricobuehlerandClaude Fable 5	2621b6e6b1	feat(core,host,android): Steam Controller 2 as-is passthrough to Linux hosts ... 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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 11:22:16 +02:00
