enricobuehler	0324719b6e	feat(host/windows): USO batched send for the GameStream video plane ... The GameStream video sender did one send() syscall per packet on Windows (the #[cfg(not(target_os="linux"))] sendmmsg_all fallback), capping throughput at high packet rates. Wire it to UDP Send Offload (the Windows analogue of Linux GSO) so each paced 16-packet burst goes out in one WSASendMsg(UDP_SEND_MSG_SIZE) syscall instead of 16, preserving the microburst pacing. Expose a reusable punktfunk_core::transport::send_uso_all (Windows-only) that reuses the proven native-plane USO primitive (send_one_uso + the uso on/off latch + uso_unsupported), with the same uniform-size guard and ≤512-segment chunking as UdpTransport::send_gso. It returns how many leading packets it sent via USO; the GameStream sendmmsg_all sends any remainder (USO off via PUNKTFUNK_GSO=0, a size-mixed burst, or a frame's short final packet) with per-packet send. On-wire packet boundaries are unchanged. Resolves #4 in docs/apollo-comparison.md. Linux build unaffected; punktfunk-core type-checks for x86_64-pc-windows-msvc. Host Windows compile deferred to CI / dev box. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-16 10:21:33 +00:00
enricobuehler	ba4e9a8672	docs(apollo): mark cursor #13 done, reclassify #21 as already-handled ... #13 (two-pass alpha+XOR cursor) implemented in capture/dxgi.rs. #21 (composite moved cursor without a new desktop frame) is already handled: DXGI returns S_OK for pointer-only updates so punktfunk recomposites in present_acquired; the original premise (stutter via timeout) was incorrect. Adds status banner + per-item resolution notes in Part 4 and Part 3. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-16 09:49:20 +00:00
enricobuehler	6d7301ccf5	fix(windows): two-pass cursor compositing (alpha + XOR) in DXGI capture ... A single DXGI cursor shape can need BOTH an alpha-blended layer AND a screen-inverting (XOR) layer at once — a masked-color text I-beam (opaque hot-spot + inverting bar) or a monochrome cursor mixing opaque and invert pixels. The old path produced ONE BGRA image per shape and picked ONE blend (cursor_invert) for the whole shape, so such mixed cursors rendered wrong (masked-color opaque pixels forced through the invert blend; monochrome (AND=1,XOR=1) invert pixels approximated as solid black). Port Apollo/Sunshine's decomposition: convert_pointer_shape now returns a CursorShape with optional alpha/xor layers; CursorCompositor holds tex_alpha + tex_xor and draw_layer renders each with its own blend (alpha = src-over, HDR-scaled; XOR = inversion, unscaled — it operates on the framebuffer reference). The CPU software path blends both layers too. Empty layers are never uploaded or drawn. Removes the single cursor_invert flag. Fixes #13 in docs/apollo-comparison.md. Independently reviewed (ship); Windows-only code — compile verified by CI / dev VM. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-16 09:48:34 +00:00
enricobuehler	f44317fb33	feat(windows): stable code-signing cert for the MSIX (one-time per-machine trust) ... Sign every MSIX build with one STABLE self-signed cert instead of a fresh per-build cert, so the Trusted People import is a one-time, per-machine step that survives upgrades (a fresh cert each build forced a re-import every time). The cert (CN=unom, SHA-1 CD1EFDEE…E941, valid to 2036) lives in the MSIX_CERT_PFX_B64 / MSIX_CERT_PASSWORD Actions secrets; its public half is checked in as packaging/punktfunk-codesign.cer and published next to each .msix. pack-msix.ps1 now always exports the signing cert's public .cer (extracted from a supplied pfx too, not just the ephemeral-generated path) and warns if the cert subject != manifest Publisher (the mismatch Add-AppxPackage would otherwise reject). Documents the path to a publicly-trusted (no-import) cert: swap the two secrets + pass a matching -Publisher. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-16 09:17:30 +00:00
enricobuehler	7bf2899301	fix(host/windows): secure-desktop black screen — capture the real frame, don't seed black ... Root cause (confirmed live: "black until I pressed a key, then the image came back"): the secure desktop (lock/login/UAC) is STATIC, and DXGI Desktop Duplication only emits a frame on CHANGE. On the normal→secure switch the duplication is rebuilt (recreate_dupl / try_reduplicate), and we then SEEDED A BLACK frame as last_present — which the static secure desktop never replaced (no change-frame) until the user pressed a key. So we streamed black. Fix: after rebuilding the duplication, CAPTURE the current desktop frame instead of seeding black. A freshly-created duplication's first AcquireNextFrame returns the full current desktop; grab it and present it. New `present_acquired` factors the frame-processing out of `acquire`; both recovery paths now call it: - recreate_dupl: after adopting the new duplication, acquire+present the real frame (born-lost ACCESS_LOST / no-initial-frame → seed black as fallback and let the 250ms-throttled caller retry — a brief flash, then real content). - try_reduplicate: adopt-first, then capture its probe frame (was discarded). Also (independently-correct safe fixes, per the adversarial review): - DesktopWatcher computes the current desktop synchronously in start() before returning, so a session that begins on the secure desktop (reconnect to a locked box) doesn't relay one stale normal-desktop frame (the "flash"). - DuplCapturer::open reasserts SudoVDA isolation at open time (mirrors recreate_dupl) — forces the secure desktop back onto the virtual output if a lock/UAC re-attached a physical monitor. - Instrumentation: dbg_black_seeds counter + a throttled warn when black is seeded, and an info when a real secure-desktop frame is captured on recovery. Pending: the user's real-lock smoke test on the 4090 (a headless PsExec LockWorkStation runs as SYSTEM and can't lock an interactive session, so this must be validated with an actual lock).

enricobuehler	cbeece119f	fix(windows): link the client as a GUI subsystem — no console window on launch ... The binary had no windows_subsystem attribute, so it linked as a console (CUI) app and Windows opened a console window alongside the WinUI window on every launch (incl. the MSIX). Add #![cfg_attr(windows, windows_subsystem = "windows")] so the windowed/MSIX launch is window-free (verified: the built exe's PE subsystem flips from WINDOWS_CUI=3 to WINDOWS_GUI=2). To keep the CLI paths usable, main now calls AttachConsole(ATTACH_PARENT_PROCESS) at startup — it binds to an existing parent console only (never creates one), so --headless/--discover still print to the launching terminal while Explorer/MSIX launches stay console-free. Adds the Win32_System_Console windows feature. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-16 09:06:31 +00:00
enricobuehler	183ddd5fa1	docs: Apollo (Sunshine fork) vs punktfunk architecture map + transfer backlog ... Map Apollo's architecture for future agents and compare against punktfunk, with a deep-dive on the Windows host (the focus area). Produced by the apollo-vs-punktfunk multi-agent workflow; every claim carries file:line into both codebases. Contents: Apollo architecture map + Apollo->punktfunk file index; subsystem parity; a reference-grade Windows-host deep-dive (DXGI/WGC capture, cursor compositing, HDR, NVENC-on-D3D11, SendInput/ViGEm, SudoVDA, SYSTEM/secure desktop); and a prioritized 96-item improvement backlog (89 Windows-host, 24 high-severity). Top confirmed Windows gaps: GameStream TLS accepts any client cert (verify_client_cert returns assertion()), no NVENC reference-frame invalidation, SudoVDA watchdog ignores its ioctl result, absolute-mouse mapping discards the virtual-desktop rect.

enricobuehler	bb11b2faf7	feat(windows): MSIX packaging + publish workflow for the WinUI client ... Package the Windows client as a signed MSIX (Start tile, clean install/uninstall) and publish it to Gitea's generic registry, mirroring the host's .deb/.rpm and the Mac's DMG. Validated end-to-end on the build VM: cargo build --release -> makeappx pack (16 payload files, 58 MB) -> signtool -> Add-AppxPackage deploy -> framework-dependency resolution all green. - packaging/AppxManifest.xml: full-trust Win32 app (Windows.FullTrustApplication + runFullTrust), templated {VERSION}/{PUBLISHER}. windows-reactor packages cleanly despite being built "unpackaged" because it calls MddBootstrapInitialize2 with OnPackageIdentity_NOOP — under MSIX identity the bootstrapper no-ops and the App SDK resolves from the manifest's PackageDependency on Microsoft.WindowsAppRuntime.2 (reactor pins MAJORMINOR 0x20000 = 2.0). - packaging/pack-msix.ps1: assemble layout (exe + reactor/SDL3 auto-staged DLLs + resources.pri + FFmpeg DLLs + tile assets), makeappx, signtool. Cert precedence: MSIX_CERT_PFX_B64 secret, else an ephemeral self-signed cert whose .cer is published alongside (swap in a real cert later, no manifest change). - assets: tile/store logos rasterized from packaging/flatpak/io.unom.Punktfunk.svg. - .gitea/workflows/windows-msix.yml: runs on the Windows runner on main pushes + win-v* tags + dispatch. MSIX version is 4-part numeric — win-vX.Y.Z -> X.Y.Z.0, else 0.2.<run>.0. shell: pwsh + CARGO_TARGET_DIR=C:\t like windows.yml.

enricobuehler	ec2907fc32	perf(host/windows): SendInput retry-on-failure model (two-process step 2) ... The injector reattached the input desktop (OpenInputDesktop + SetThreadDesktop, two syscalls) before EVERY event. Now it stays bound to its desktop and only reattaches on a SendInput short write (the input desktop switched into UAC/lock) + retries once — Sunshine's model. No steady-state per-event overhead; still follows the desktop across the secure boundary, serving both desktops. Validated on the RTX 4090 (host as SYSTEM): client-rs --input-test injected for ~6s with no "blocked desktop" errors. Completes all 6 steps of the two-process secure-desktop build; only a real-UAC user smoke test remains. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-16 08:30:49 +00:00

enricobuehler	1b68890dbf	feat(host/windows): two-process step 6 — helper relaunch watchdog ... A WGC-helper exit (crash, or a console disconnect killing its session) used to end the stream. Now virtual_stream_relay rebuilds the output + helper and resumes on the new helper's opening IDR. Rebuild — not respawn-on-the-old-target — because an abruptly-killed helper leaves the SudoVDA's DXGI output briefly unresolvable ("no DXGI output for target N yet"), and a console reconnect needs a fresh output in the new session; `build` (the same path reconfigure uses) recreates both. Bounded: 500ms backoff per attempt, give up after MAX_HELPER_FAILS (20) consecutive failures; the counter resets on the first relayed frame. Live-validated on the RTX 4090 (host as SYSTEM): force-killed the helper PID mid-stream → exactly one "WGC helper exited — rebuilt output + helper fails=1" → the stream recovered and client-rs decoded 645 HEVC Main-10 frames continuously across the kill (an earlier respawn-on-stale-target attempt storm-failed with "no DXGI output", which the rebuild fixes).

enricobuehler	e39f65a228	ci(windows): set CARGO_TARGET_DIR=C:\t — dodge MAX_PATH in CMake-from-source builds ... With the BOM fixed (shell: pwsh), the build got far enough to compile audiopus_sys, which does a CMake-from-source build of libopus. The runner's host workdir sits deep under C:\Windows\System32\config\systemprofile\.cache\act\<hash>\hostexecutor\, so target\debug\build\ audiopus_sys-*\out\build\CMakeFiles\CMakeScratch\TryCompile-*\...\.tlog overran Windows' 260-char MAX_PATH and MSBuild's tracker failed to create its .tlog (DirectoryNotFoundException -> MSB6003, "CL.exe konnte nicht ausgeführt werden"). Pointing CARGO_TARGET_DIR at C:\t shortens every nested build path well under the limit (fixes audiopus_sys + SDL3, both CMake-from-source).

enricobuehler	4edfcd4b43	feat(host/windows): two-process mux test toggle + live-validate step 5 ... PUNKTFUNK_SECURE_TEST_PERIOD_MS=N drives a square-wave secure/normal toggle in virtual_stream_relay (instead of the real DesktopWatcher), to exercise the mid-session helper↔DDA mux without a live UAC/lock. Gated behind the env var, in the style of PUNKTFUNK_VIDEO_DROP / PUNKTFUNK_FEC_PCT. Live-validated on the RTX 4090 (host as SYSTEM): with a 4s toggle the mux switched secure(DDA)↔normal(WGC relay) cleanly 5× in one session and the client decoded 308 HEVC Main-10 frames continuously across every switch — the wait-for-IDR latch held with no decode break. The real Winlogon DDA capture is pre-proven by the single-process secure path (f4b4a6c); the toggle exercises the new surface (the mux). Doc updated with the validation + the SYSTEM-mode audio caveat. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-16 08:13:16 +00:00
enricobuehler	372483abf0	ci(windows): use shell: pwsh (PowerShell 7) — fixes GITHUB_ENV BOM corruption ... Windows PowerShell 5.1's Out-File -Encoding utf8 prepends a UTF-8 BOM, corrupting the first GITHUB_ENV line so CARGO_WORKSPACE_DIR silently never got set -> windows-reactor build.rs panic -> CI build failed (runs 8765/8768). pwsh 7 writes UTF-8 without a BOM. Installed PowerShell 7.6.2 MSI on the runner and put C:\Program Files\PowerShell\7 on the daemon wrapper PATH so jobs find pwsh; switched all windows.yml steps to shell: pwsh. (Reproduced locally with CARGO_WORKSPACE_DIR set: the build is green in 2m37s — the BOM was the only issue.) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-16 08:10:30 +00:00
enricobuehler	8d6cbb81fe	fix(host/windows): merge host PUNKTFUNK_* env into the WGC helper's environment ... CreateProcessAsUserW gives the spawned helper the *user's* environment block, so the host's PUNKTFUNK_ENCODER=nvenc (and ZEROCOPY/PERF/…) were dropped and the helper fell back to the software (H.264-only) encoder — the client negotiated H265 → "WGC helper exited". `merged_env_block` now parses the user block, strips any PUNKTFUNK_* it carried, overlays this (host) process's PUNKTFUNK_* vars, and passes the merged UTF-16 block. Validated live on the RTX 4090 (host as SYSTEM): the helper spawns via CreateProcessAsUserW, runs WGC with no hang (HDR FP16 BT.2020 PQ), opens NVENC (D3D11 Main10), and relays AUs over the pipe — client-rs decoded 411 HEVC Main-10 frames over the LAN. Step 4 (spawn + relay) complete. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-16 08:05:43 +00:00
enricobuehler	140209bbfc	feat(host/windows): two-process secure-desktop step 5 — DDA mux on Winlogon ... `virtual_stream_relay` now muxes the AU source by input desktop. A DesktopWatcher (SYSTEM-only Winlogon-name poll) drives it: the user-session WGC helper relay feeds the normal (Default) desktop; the host's OWN DDA capturer+encoder — opened lazily on the first secure transition, on the same SudoVDA target with a no-op keepalive (the host still holds the real isolation owner) — captures the secure (Winlogon: UAC/lock/login) desktop that WGC can't see. Every switch latches "wait for IDR" and forces the now-active source to emit a keyframe (the two encoders keep independent infinite-GOP state, so the client must resume on an IDR); returning to the helper also drains its stale buffered AUs first. Reconfigure drops the stale-target DDA; keyframe requests route to the live source. Send path (FEC/seal/paced-send) unchanged. Also: wgc_relay gains try_recv (drain on switch-back); open_dda takes dims as args (avoids a closure borrow of the reassigned cur_mode); the forward! macro returns bool with `break 'outer` at the call site (no in-macro label hygiene). cfg-gated windows-only. Live validation (UAC switch over a session) pending. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-16 07:55:29 +00:00
enricobuehler	9f50b3930d	feat(host/windows): two-process secure-desktop step 4 — spawn helper + relay AUs ... The SYSTEM host now sources the normal-desktop video from a user-session WGC helper instead of capturing in-process (WGC won't activate as SYSTEM). New `capture/wgc_relay.rs`: `HelperRelay::spawn` launches `m3-host wgc-helper` in the interactive user session via CreateProcessAsUserW (WTSQueryUserToken → DuplicateTokenEx(TokenPrimary) → lpDesktop="winsta0\\default", CREATE_NO_WINDOW) with three anonymous pipes — stdout (framed Annex-B AUs → parsed back to RelayAu), stdin (control: force-keyframe), stderr (helper logs → host tracing). The host holds the SudoVDA keepalive (sole isolation/topology owner); the helper captures by GDI name only. m3.rs: `virtual_stream` dispatches to the new `virtual_stream_relay` when `should_use_helper()` (running as SYSTEM, or PUNKTFUNK_FORCE_HELPER; disable with PUNKTFUNK_NO_HELPER). The relay loop feeds the existing send thread — same FEC/seal/paced-send path. Reconfigure rebuilds the output + re-spawns the helper; keyframe requests forward over the control pipe; helper pts_ns (same-machine monotonic clock) is used directly as capture_ns. Disconnect ends the stream (step 6 adds the relaunch watchdog). wgc_helper.rs: reads the stdin control byte to request an IDR; --bit-depth flag threaded through so SDR 10-bit (Main10) negotiation reaches the helper's encoder. cfg-gated windows-only; Linux/macOS build unaffected. Step 5 (DesktopWatcher mux to host DDA on the Winlogon secure desktop) is next. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-16 07:43:20 +00:00
enricobuehler	7a814b5f18	ci(windows): restore paths filter + document global runner scope ... Re-add the paths filter (the trigger was never the problem — the runner was registered at the wrong scope, so org-repo runs found 'no fitting runner' despite the runner showing idle). Document in setup-windows-runner.ps1 that the registration token must be GLOBAL (Site Administration -> Actions -> Runners), like the Linux runner. CARGO_WORKSPACE_DIR is set via GITHUB_ENV in a step (the job-env ${{ github.workspace }} form didn't resolve, leaving it unset -> reactor build.rs panic).

Opens WGC on the EXISTING SudoVDA output by GDI name only (never creates a virtual output — a second topology owner re-trips the ACCESS_LOST born-lost storm), encodes via NVENC, and ships framed Annex-B AUs on stdout for the SYSTEM host to relay onto the live QUIC session: `[u32 magic "PFAU"][u32 len][u64 pts_ns][u8 keyframe][data]`. tracing → stderr so stdout stays the pure AU stream. cfg-gated windows-only; Linux build unaffected. scripts/headless/win-build.cmd: the canonical box build script (sets PUNKTFUNK_BUILD_VERSION so build.rs stamps the version + the NVENC LIB path).

enricobuehler	dd9dfecbe4	ci(windows): drop paths filter (trigger reliability) + NO_COLOR runner logs ... The paths filter wasn't dispatching the run on the newly-added workflow (the runner is healthy and 'declare successfully', but received no task). Match apple.yml: trigger on every push to main + PRs.

enricobuehler	80e222d3b8	feat(host/windows): DesktopWatcher (secure-desktop detection) — step 1 of the two-process build ... Polls the input-desktop name (OpenInputDesktop + GetUserObjectInformationW(UOI_NAME)) on its own thread → Default/Winlogon atomic; the authoritative normal-vs-secure signal for the capture mux + input path (WTS notifications miss UAC). Not yet wired into the mux (needs the SYSTEM host + WGC helper, steps 3-5 in docs/windows-secure-desktop.md). NOTE: detecting the secure desktop requires the host to run as SYSTEM (a user-token process can't OpenInputDesktop the Winlogon desktop).

enricobuehler	5c2bcbc2a2	docs(windows): secure-desktop two-process design + WGC impersonation attempt (vestigial) ... Validated design for adding secure-desktop (UAC/lock/login) coverage on top of the shipped WGC animation fix. Key verified constraint: WGC won't activate under SYSTEM (0x80070424) even with thread-level ImpersonateLoggedOnUser, and DDA+SendInput on Winlogon need LOCAL_SYSTEM — so one process can't do both. Architecture: SYSTEM host (QUIC + SudoVDA + DDA-secure + SendInput + AU mux) + a USER-session WGC helper (CreateProcessAsUser) that relays encoded Annex-B AUs over a named pipe; the host muxes helper-AUs (normal desktop) vs its own DDA encoder (secure desktop), switched by a desktop-name watcher. No shared GPU texture (rejected — MIC/keyed-mutex pain); just AU bytes. docs/windows-secure-desktop.md has the ordered, box-testable steps. The impersonate_active_user() in wgc.rs is kept as a harmless no-op (under a user-token process WTSQueryUserToken fails → no impersonation → WGC works natively); it does NOT make WGC work under SYSTEM (the two-process design uses a real user process for WGC instead). + Win32_System_RemoteDesktop.

enricobuehler	589b364c01	ci(windows): fix runner registration CWD + capture clean daemon logs ... Two fixes after live setup on home-windows-1: register from $RunnerHome (act_runner writes .runner relative to CWD, so it must run there — it had landed in the SSH home and the daemon couldn't find it), and run the daemon under cmd-level redirect (>> runner.log 2>&1) so its native stderr stays out of PowerShell's error stream.

The daemon's env wrapper hard-codes this box's MSVC/WinUI toolchain (cargo/rustup, NASM, CMake, LLVM, FFmpeg, the ASCII CARGO_HOME SDL3's PCH needs) so the Windows workflow inherits a working toolchain.

enricobuehler	28ab448a29	feat(host/windows): WGC capture backend (overlay/HDR-correct) with watchdog'd DDA fallback ... The capture-architecture reset from the research: add a Windows.Graphics.Capture (WGC) backend that captures the COMPOSED desktop — including the overlay/independent-flip/MPO planes DXGI Desktop Duplication misses — which structurally fixes the frozen HDR animations + video (proven live: a WGC frame decodes to the real 5120x1440 HDR content DDA freezes on). It reuses the whole pipeline unchanged: the WGC frame's GPU texture → same scRGB→BT.2020-PQ shader → NVENC zero-copy; the OS composites the cursor (IsCursorCaptureEnabled) so no manual cursor pass. crates/punktfunk-host/src/ capture/wgc.rs; find_output/make_device/HdrConverter/nudge_cursor_onto made pub(crate) for reuse. Reliability findings + mitigations (live on the RTX 4090): - WGC can't activate under the SYSTEM account (0x80070424) — it needs the interactive user token. The host must run as the user for WGC (run.cmd: drop PsExec -s). DDA still needs SYSTEM for the secure desktop — that token reconciliation (impersonation) is the remaining task. - WGC's Direct3D11CaptureFramePool::CreateFreeThreaded intermittently HANGS on the headless SudoVDA (IddCx) display, correlated with accumulated SudoVDA churn (failed REMOVEs leaving lingering displays); clean-state opens reliably. Since it's a blocking hang, capture_virtual_output runs WGC open on a watchdog thread with a 5s timeout and falls back to DDA on hang/error — the session is NEVER left black: WGC when it opens (fixed animations), DDA otherwise. First-frame nudge added (WGC fires FrameArrived on change; a static desktop otherwise never delivers the first frame). - Default WGC; PUNKTFUNK_CAPTURE=dda forces DDA. DDA path unchanged.

enricobuehler	84e17fbb49	feat(windows-client): polish the WinUI 3 UI — Mica, cards, typography ... The first cut was a flat stack of buttons. Reworked the chrome to match the windows-reactor gallery's look: - Mica backdrop on the window. - A centred, scrollable, max-width column (`page()` helper) instead of full-width sprawl. - Card surfaces (`border` + `ThemeRef::CardBackground`/`CardStroke`, rounded, padded) grouping content, with all-caps section labels. - Host rows are clickable cards: name (semibold) + address + a PIN/Open/Paired badge + chevron, laid out with a grid so the badge/chevron sit right; tap to connect. - Header row with title + Settings button; a ProgressRing while searching / connecting; settings as grouped "Stream" / "Audio" cards; the pairing screen is a centred card. Pure styling/layout — no logic change. Build + clippy + fmt green on x86_64-pc-windows-msvc. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-16 05:28:15 +00:00
enricobuehler	3b3940dc8c	docs(windows-client): correct the WinUI 3 record — reactor IS used (PR #4499) ... The winit-commit docs claimed "Reactor rejected, no SwapChainPanel hatch" — that was wrong. windows-rs PR #4499 added the SwapChainPanel widget; the client now uses WinUI 3 via windows-reactor. Update CLAUDE.md M4, the bootstrap-doc status banner (reactor integration: pinned git dep, CARGO_WORKSPACE_DIR, App-SDK build.rs, LL-hook stream input), and the docs-site clients page (WinUI 3, launch-and-pick-a-host).

enricobuehler	5029fa727e	feat(windows-client): stream input — Win32 low-level keyboard/mouse hooks ... windows-reactor exposes no raw key-down/up or pointer-position/wheel events (only keyboard accelerators + pointer button-state), so the WinUI 3 stream page captures input below XAML via WH_KEYBOARD_LL / WH_MOUSE_LL, installed on the UI thread when the stream page mounts and removed on unmount (held keys/buttons flushed). The SwapChainPanel fills the window, so the pointer maps through the client rect (Contain-fit into the negotiated mode); keys carry the native Windows VK directly (the wire contract — no table needed). While captured, events inside the video area are swallowed so Alt+Tab/Win reach the host; Ctrl+Alt+Shift+Q toggles capture; clicks on the title bar (outside the client rect) pass through. Mouse buttons (L/M/R/X1/X2), vertical + horizontal wheel, and absolute motion all forwarded. Build + clippy + fmt green on x86_64-pc-windows-msvc.

enricobuehler	4994f7f4ba	feat(windows-client): WinUI 3 (windows-reactor) UI — host list, settings, pairing, SwapChainPanel present ... Replaces the winit + raw-HWND-D3D11 shell with a native WinUI 3 UI via windows-reactor (a declarative React-like framework backed by WinUI). The earlier "Reactor can't host a swapchain" read was wrong — PR #4499 (merged 2026-06-01) added a SwapChainPanel widget with `set_swap_chain` over `CreateSwapChainForComposition`. Builds + clippy + fmt green on x86_64-pc-windows-msvc. - Cargo: drop winit/raw-window-handle; add windows-reactor + the `windows` crate, both pinned to the SAME windows-rs commit (b4129fcc) so the `IDXGISwapChain1` handed to `set_swap_chain` satisfies reactor's `windows_core::Interface`. Reactor's build.rs downloads the Windows App SDK NuGets + stages the bootstrap DLL/resources.pri — it requires `CARGO_WORKSPACE_DIR` set (now in the VM build env); /temp + /winmd gitignored. - present.rs: composition swapchain (B8G8R8A8 FLIP_SEQUENTIAL premultiplied) bound to the SwapChainPanel; WARP fallback, runtime D3DCompile shaders, dynamic RGBA texture, Contain-fit letterbox; driven by reactor's per-frame `on_rendering`. - app.rs: the WinUI 3 shell — host list (live mDNS + saved + manual), settings (resolution/ refresh/mic combos+toggle), in-app SPAKE2 PIN pairing screen, and the stream page. Trust gate mirrors the GTK client (pinned → silent, pair=optional → TOFU, else PIN); a pinned-fp mismatch routes to re-pair. The session pump + decoded-frame handoff cross to the UI thread via a Mutex side-channel + thread-locals (the SwapChainPanel sample's pattern). - gamepad: `ctl` sender now `Arc<Mutex<…>>` so GamepadService is `Sync` (shared across the UI and session-pump threads). main.rs: windowed = in-app UI; `--headless`/`--discover` keep the CLI paths. Not yet wired: raw stream keyboard/mouse input (next commit — reactor exposes no raw key/ pointer events, so it needs Win32 low-level hooks or Microsoft.UI.Xaml bindings). On-glass validation pending a display (the dev VM is headless/GPU-less). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-15 22:58:48 +00:00
enricobuehler	296b976b8f	feat(windows-client): SDL3 gamepads + docs — full stage-1 parity, MSVC-green ... Adds the SDL3 gamepad service (near-verbatim port of the GTK client's — SDL3 is cross-platform) and wires it into the winit app: per-session capture (buttons/axes, DualSense touchpad + motion 0xCC), feedback (rumble, lightbar, raw DualSense effects), single-pad-forwarded model with auto pad-type from the physical controller. Built from source on Windows (no system SDL3). - gamepad.rs: GamepadService (app-lifetime SDL thread) attach/detach on session connect/end; auto_pref resolves "Automatic" to the attached pad's type. - app.rs: hold the service, attach on Connected, detach on Ended/Failed/close. Also simplify the keydown path (drop the identical if/else arms). - main.rs: start the service for the windowed path, resolve GamepadPref from settings + the physical pad. Build gotcha documented + fixed in the dev loop: SDL3's build-from-source MSVC precompiled-header chokes on the `ü` in the dev box's username embedded in the cargo registry path (MSB8084/C4828) — CARGO_HOME must be an ASCII path (C:\Users\Public\.cargo). Unrelated to our code. Docs: CLAUDE.md M4 + docs/windows-client-bootstrap.md status banner (winit-not-Reactor rationale, CARGO_HOME gotcha, what's pending) + docs-site clients.md "Windows desktop client (in development)". Crate is build + clippy + fmt + test green on x86_64-pc-windows-msvc. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-15 22:11:35 +00:00
enricobuehler	e4bdec97bd	feat(windows-client): winit + D3D11 present, WASAPI render, input — builds live on MSVC ... Builds on the prior headless scaffold (which was committed but never VM-built — its audio.rs had two non-compiling wasapi calls). This makes the whole crate build + clippy + fmt + test green on x86_64-pc-windows-msvc and adds the windowed client. - Fix audio.rs: `DeviceEnumerator::new()?.get_default_device(...)` (the free fn doesn't exist) and the 3-arg `write_to_device` (wasapi 0.23). WASAPI shared-mode event-driven render + mic capture now compile and link. - present.rs: D3D11 renderer with WARP fallback (GPU-less dev box), runtime-compiled fullscreen-triangle shaders, dynamic RGBA video-texture upload, Contain-fit letterbox draw, and a flip-model swapchain on the window HWND. - app.rs: winit 0.30 ApplicationHandler — present loop + Moonlight-style click-to-capture input (keyboard via the physical-KeyCode→VK keymap, absolute mouse, wheel, F11), held state flushed on release/focus-loss. - keymap.rs: winit physical KeyCode → Windows VK (layout-independent positional mapping, the analogue of the Linux client's evdev table). - main.rs: windowed default + `--headless` counting mode, `--discover` (mDNS list), `--pair PIN` (SPAKE2 ceremony), `--pin HEX`/known-host/TOFU trust, settings-backed CLI defaults. UI decision: winit + raw D3D11 (the bootstrap doc's sanctioned fallback), confirmed by a research pass — windows-rs "Reactor" ships no SwapChainPanel / SetSwapChain escape hatch, so it can't host the presenter; winit+WARP validates on the GPU-less VM. Native-chrome host-list/settings GUI + D3D11VA hardware decode + 10-bit/HDR present are follow-ups. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-15 21:59:40 +00:00
enricobuehler	ef30afcf0b	fix(apple): fill the notch in macOS fullscreen — stop letterboxing below the camera housing ... The macOS sessionView branch was missing the .ignoresSafeArea() its iOS/tvOS siblings have, so in fullscreen the stream was laid out in the safe area below the notch; the aspect-fit video then scaled down to that smaller area and left black borders. Add .ignoresSafeArea() so the stream fills the whole display including behind the camera housing (a thin top-center strip occluded — normal fullscreen- video behavior); at the display's native mode it's now a 1:1 fill. Inert in windowed mode and on non-notched displays. NSPrefersDisplaySafeAreaCompatibilityMode is deliberately not used (it shrinks the whole window with borders on all sides).

enricobuehler	4b0b775e8e	fix(apple): allow CoreHaptics audioanalyticsd mach-lookup under the macOS sandbox ... GCDeviceHaptics.createEngine returns a CHHapticEngine (the only controller-rumble API on Apple platforms); starting it spins up CoreHaptics, which looks up the system audio-analytics daemon over Mach. The App Sandbox denies that global-name lookup and the framework's precondition turns the denial into a hard crash ("Process is sandboxed but com.apple.security.exception.mach-lookup.global-name doesn't contain com.apple.audioanalyticsd") the moment a controller's rumble engine starts. Add the documented, App-Store-acceptable temporary-exception whitelisting exactly that one service. Verified embedded into the signed binary (codesign -d --entitlements) alongside the existing entitlements. macOS-only (iOS/tvOS reject temporary-exception keys and don't need it).

enricobuehler	b9f4cf1f3e	fix(host/windows): don't 2-way-split-encode Main10 — it's SLOWER on Ada (fixes broken HDR animations) ... The "broken animations in HDR" was an encode-throughput cliff, not the ACCESS_LOST churn. Measured at 5120x1440@240 HEVC Main10 on the RTX 4090: forced 2-way split-encode = 7.6 ms/frame (~131 fps, well over the 4.17 ms/240fps budget → choppy), while SINGLE engine = 2.8-3.9 ms/frame (~256-357 fps, fits 240). The split/merge overhead dominates for 10-bit; a single Ada NVENC engine already handles 5K@240 Main10 comfortably. So the split decision now forces DISABLE for Main10 (bit_depth >= 10), keeping the existing forced-2 only for 8-bit above 1 Gpix/s. PUNKTFUNK_SPLIT_ENCODE still overrides. Added a split-mode log line. Validated live on the 4090: encode_us_p50 7.6 ms → 3.9 ms at 5K240 HDR with no env override.

enricobuehler	b1e95a386f	fix(host/windows): tiered DXGI recovery — cheap re-DuplicateOutput for the HDR ACCESS_LOST churn ... The HDR path produced a constant ACCESS_LOST churn during real desktop activity (window resize / Start menu / DWM transitions): the duplication keeps getting invalidated but the OUTPUT stays valid (probe passes — 0 born-lost over 72 rebuilds). The old recovery did a FULL rebuild (new device + factory) on every loss, which re-inits NVENC + seeds black + was throttled to 4x/s → mostly-frozen, re-init churn = "broken animations". Now recovery is tiered (mirrors Sunshine): try_reduplicate() does a fresh DuplicateOutput on the EXISTING device+output — no new device, so NO encoder re-init, NO black seed, gpu_copy/HDR textures/last_present kept → frames resume immediately. Only a genuine output loss (secure-desktop switch) or a dead device (DEVICE_REMOVED/RESET) falls back to the full, throttled recreate_dupl. Both paths probe the new duplication and reject a born-lost one. Validated synthetically (1080p60 + 5120x1440@240 HDR): pipeline stable, 0 churn, frames flow. The real-desktop churn needs live validation (can't synthesize DWM animations). Secure-desktop "UI never appears in-session" is a separate issue (output gone in-session; only a fresh monitor re-add works) — still open.

enricobuehler	0a3b92d994	fix(host/windows): HDR cursor brightness (203-nit) + probe-before-adopt recovery; windows-client bootstrap doc ... - HDR cursor: sRGB→linear decode + scale to HDR graphics white (PUNKTFUNK_HDR_CURSOR_NITS, default 203 per BT.2408) in the FP16 cursor composite, so it's no longer ~2.5x too dim. SDR path unchanged; the masked-color (I-beam) inversion blend left unscaled. Cursor cbuffer widened 16→32 + bound to PS. (Validated live: cursor now correct brightness in HDR.) - Secure-desktop recovery: recreate_dupl now PROBES the rebuilt duplication with a 50ms AcquireNextFrame and only adopts it when live (Ok/WAIT_TIMEOUT); a born-lost one (immediate ACCESS_LOST) is dropped so the caller repeats the last frame + retries. Plus reassert_isolation() re-detaches physical displays on every recovery (re-routing the secure/HDR desktop to the virtual output, the delta a fresh reconnect has). NOTE: the born-lost ACCESS_LOST storm in HDR is NOT yet resolved by these — still under investigation (animations/secure-UI/cursor-trail in HDR remain). - docs/windows-client-bootstrap.md: handoff for the native Windows Rust client (windows-rs Reactor + WinUI 3 SwapChainPanel, D3D11VA decode, WASAPI audio, SDL3 input; ports crates/punktfunk-client-linux; 10-bit/HDR present; dev boxes + gotchas).

enricobuehler	e99a1aea43	fix(apple): resolve QoS priority inversions + two Swift concurrency warnings ... Priority inversions (Thread Performance Checker): the Apple client drains every plane on .userInteractive threads (video pump, audio, gamepad feedback) and connects on a .userInitiated Task, but the connector's producer threads ran at the default QoS — so a high-QoS consumer parked waiting on a lower-QoS producer. Pin the connector's producers (outer worker thread, all tokio runtime threads via on_thread_start, and the data-plane spawn_blocking pump) to .userInteractive on Apple so they match the consumers. #[cfg(target_vendor = "apple")] helper using the existing libc dep; no-op off Apple, no Swift-side change (no latency regression). GamepadFeedback.swift: the init's MainActor hop captured self implicitly-strong while the inner $active sink captured it weakly — capture [weak self] in the hop too (the sink stays weak to avoid the retain cycle). StreamPump.swift: the @Sendable pump-thread closure captured the non-Sendable AVSampleBufferDisplayLayer. enqueue/flush are documented thread-safe and only the pump thread drives it after start(), so assert that with nonisolated(unsafe). cargo build/test/clippy/fmt green (core + host); xcframework rebuilt; swift build + iOS/tvOS targets clean with both warnings gone. Runtime confirmation of the inversion warnings needs a GUI run under Xcode's Thread Performance Checker.

enricobuehler	bbabc04bca	feat(hdr): Windows HDR10 + 10-bit end-to-end, negotiated; non-blocking capture recovery ... Adds true HDR (BT.2020 PQ) and 10-bit (HEVC Main10) streaming, negotiated so an 8-bit/SDR client is never sent a stream it can't decode, plus a robust fix for the capture losing the stream across a secure-desktop transition. Protocol (punktfunk-core/quic.rs): - Hello gains `video_caps` (VIDEO_CAP_10BIT / VIDEO_CAP_HDR), Welcome gains `bit_depth`, both as optional trailing bytes (back-compat). client-rs advertises 10-bit via PUNKTFUNK_CLIENT_10BIT; the connector advertises 0 for now (in-band detection drives the native clients). Regenerated punktfunk_core.h. Windows host: - 10-bit Main10: host enables it only when the client advertised VIDEO_CAP_10BIT AND PUNKTFUNK_10BIT is set; threaded through open_video → NVENC (profile Main10, pixelBitDepthMinus8). - HDR: when the captured desktop is scRGB FP16 (R16G16B16A16_FLOAT, HDR on), copy it to an FP16 surface, composite the cursor there, convert scRGB → BT.2020 PQ 10-bit (R10G10B10A2) via a shader, and encode HEVC Main10 with the BT.2020/PQ colour VUI (ABGR10 input). Fixes the freeze + cursor-trail that came from feeding FP16 into the BGRA path. Reacts dynamically to the HDR toggle. - Capture recovery: rebuild is now a single NON-BLOCKING attempt, throttled to ~4×/s, repeating the last good frame between attempts (format-tagged last_present). During a secure-desktop dwell SudoVDA's output is gone; the old blocking 12 s retry starved the send loop for seconds so the client timed out and disconnected — now the session stays fed (frozen) until the desktop returns. Also seeds a black frame on recovery. Apple client (PunktfunkKit): - Detects HDR in-band from the stream VUI (PQ transfer function), decodes to 10-bit P010, and presents via an rgba16Float + BT.2020 PQ CAMetalLayer with EDR; SDR path unchanged. Switches automatically on a mid-session HDR toggle. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-15 20:28:52 +00:00
enricobuehler	f5eae24c87	feat(apple): tabbed macOS Settings + stats-overlay placement/toggle + Stream menu ... The macOS Settings window had outgrown one scrolling pane — split it into a tabbed preferences window (General / Display / Audio / Controllers / Advanced). Each settings group is now a shared @ViewBuilder section, so iOS keeps its single grouped Form and tvOS its pushed-picker layout, each defined once. No setting moved or dropped. New statistics-overlay controls (Settings → Display → Statistics): a show/hide toggle (DefaultsKey.hudEnabled) and a corner picker (HUDPlacement / DefaultsKey.hudPlacement) — the HUD moves to the chosen corner and aligns its text to that edge. A Scene-level "Stream" menu (StreamCommands) carries Show/Hide Statistics (⌘⇧S) and Disconnect (⌘D). Disconnect moved off the HUD button into the menu so it survives the overlay being hidden, wired via .focusedSceneValue. On iOS a material-backed exit chip appears when the HUD is hidden (touch users have no menu/⌘D); tvOS disconnect is unchanged (Siri-Remote Menu button). Builds on macOS/iOS/tvOS; swift test green. Adversarially reviewed (8 findings refuted, 2 minor — the iOS exit-chip contrast fix is included here). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-15 22:11:39 +02:00
enricobuehler	26fbd9ec64	perf(host/windows): zero-copy NVENC — encode the capturer's texture in place (halve 3D-engine load) ... The Windows host pegged the GPU 3D engine at ~97% during high-fps desktop streaming — measured (per- process GPU-engine counters) as OUR process, not DWM. Cause: TWO VRAM->VRAM CopyResource per frame (dupl->gpu_copy in the capturer, then gpu_copy->nvenc_pool in the encoder), and on Windows D3D11 routes copies to render-target textures through the 3D engine (the DMA copy engine sat idle at 7%), so at 240 fps they saturate it and contend with a game's own rendering. Eliminate the second copy: NVENC now registers the capturer's D3D11 texture directly (cached by raw pointer, the cloned texture kept alive until unregister) and encode_pictures it IN PLACE — no encoder-owned input pool, no per-frame copy. Safe because the host encode loop is synchronous (capture -> submit -> poll, where lock_bitstream blocks until the encode finishes), so the capturer never overwrites the texture mid-encode; documented in the module header in case that ever changes. 2 GPU copies/frame -> 1 (the remaining dupl->gpu_copy is unavoidable; that DXGI surface is transient). Measured: SM/compute ~10-15% at ~217 fps 5K (was ~20% at only ~48 fps with two copies), 3687 frames decoded clean. Windows-only; Linux/macOS unaffected.

enricobuehler	c830246037	feat(host/windows): UDP send offload + NVENC 2-way split-encode (1 Gbps+ / 5K@240) ... The Windows host couldn't sustain high-throughput / high-fps streams — two gaps vs the Linux host, both found via live RTX 4090 measurement (PERF timing + nvidia-smi per-engine attribution): - UDP Send Offload (USO). punktfunk-core's UdpTransport sent one packet per `send` syscall on Windows (send_batch/send_gso were Linux-only), capping throughput at high packet rates. Add a Windows `send_gso` override using `WSASendMsg` + `UDP_SEND_MSG_SIZE` (the Windows analogue of Linux UDP GSO) via windows-sys — one syscall segments a coalesced <=512-segment super-buffer to the connected peer. On by default with auto-fallback (PUNKTFUNK_GSO=0 disables, error latches off); plugs into the existing paced send path. SO_SNDBUF (32MB) was already cross-platform. - NVENC 2-way split-frame encoding. A single Ada NVENC session tops out ~0.8 Gpix/s, so 5K@240 (1.77 Gpix/s) took ~8 ms/frame -> a ~125 fps ceiling at high motion (the in-game stutter). Set NV_ENC_INITIALIZE_PARAMS.splitEncodeMode = TWO_FORCED above ~1 Gpix/s (matching the Linux libavcodec split_encode_mode path) to use both 4090 encoders — measured ~8 ms -> ~4 ms/frame at throughput. Env override PUNKTFUNK_SPLIT_ENCODE; init-failure fallback disables it (e.g. H264). Windows-only paths; Linux/macOS unaffected. Builds clean on x86_64-pc-windows-msvc.

enricobuehler	49cdafc042	feat(android): connect-screen redesign — Apple-style cards, FAB + bottom sheet, fixed status bar ... Polish pass on the connect screen. - Host cards: ElevatedCard with a colored letter-avatar (Apple-contact style), name + address, a colored status pill (Paired / PIN pairing / Trust on first use), and an overflow menu with Forget on saved hosts. Tapping a card connects. Unifies the old saved/discovered rows into one HostCard. - Manual connect moved behind an "Add host" ExtendedFloatingActionButton that opens a ModalBottomSheet with the Host/Port form (the current M3 pattern) — declutters the list. - Empty state when there are no saved/discovered hosts; single scrollable column; removed the "core ABI v2" footer. - Status bar: enableEdgeToEdge driven explicitly dark (transparent bars + light icons) so the status/nav bars blend with our always-dark surface instead of showing a black band (the no-arg edge-to-edge had picked the system light/dark theme). Verified live (emulator screenshots): cards render with avatars + status pills + Forget menu; the FAB opens the bottom-sheet form; the status bar blends with light icons.

enricobuehler	f4b4a6c1e4	feat(host/windows): native res, cursor, secure-desktop capture, windowless SYSTEM launch ... Live-validated Mac <-> RTX 4090 at the display's native 5120x1440@240: - Resolution: set_active_mode enumerates the IDD's advertised modes and sets the requested resolution at the best supported refresh (keeps 5120x1440@240; no more silent fallback to the 1080p OS default when an exact mode is briefly unavailable). - Bitrate auto-cap: NVENC init probes and steps the average bitrate down to the GPU's codec-level max so a high client bitrate connects (matches the Linux host; we do not split NVENC sessions). - Mouse cursor: DXGI duplication excludes the HW cursor; capture the pointer shape/position (GetFramePointerShape) and GPU-composite it before NVENC. Color cursors alpha-blend; masked-color (the text I-beam) uses an INV_DEST_COLOR inversion blend so the caret inverts the screen and shows on any background (no black box); monochrome handled too. - Secure desktop (lock / login / UAC): run as SYSTEM in the interactive session, follow the input desktop via SetThreadDesktop, and on the WinSta switch recreate the D3D11 device and re-resolve the virtual output's GDI name from the stable SudoVDA target id (the name changes across the topology rebuild; the old failure hunted the stale \\.\DISPLAYn and dropped). ACCESS_LOST / INVALID_CALL / device-removed are recoverable, and a mid-stream resolution change is followed (capturer + NVENC re-init at the new size). isolate_displays detaches other monitors so Winlogon renders to the virtual output. One real session recovered 1012 desktop switches and completed cleanly. Windows-only backends; Linux/macOS unaffected. Builds clean on x86_64-pc-windows-msvc.

The signing rollout is confirmed end to end: the latest published RPM (0.2.0-0.ci1089) carries a header GPG signature (added by `rpm --addsign`) and passed the in-CI `rpmkeys --checksig` self-verify before publishing (a bad/unsigned build fails that gate and never reaches the registry). So flip every .repo snippet from gpgcheck=0 to gpgcheck=1 and add the package-signing public key (served from the generic registry, committed at packaging/rpm/RPM-GPG-KEY-punktfunk) to gpgkey= alongside the Gitea metadata key — dnf/rpm-ostree imports both. Covers rpm/README, packaging/README, the bootc Containerfile, and the docs-site bazzite/fedora-kde install pages; rpm/README's signing section reframed from "dormant/enabling" to active (+ key-rotation notes).

enricobuehler	ecd7d4a7e3	feat(android): mic uplink + connect-screen redesign ... Microphone uplink (client → host's virtual mic, 0xCB) and a cleaner connect screen. Mic (Rust-heavy, mirrors the audio playback path in reverse): - crates/punktfunk-android/src/mic.rs: AAudio LowLatency **input** → realtime callback hands captured f32 to a channel → a worker thread Opus-encodes 20 ms stereo frames (48 kHz, VOIP, 64 kbps) and calls NativeClient::send_mic. MicCapture owns the stream + encode thread (RAII stop). - session.rs: SessionHandle gains a `mic` slot; nativeStartMic/nativeStopMic JNI (mirror of audio); stopped in Drop. NativeBridge: the two externs. - Settings: a `micEnabled` flag + a Microphone toggle in SettingsScreen that requests RECORD_AUDIO (denied → stays off). StreamScreen starts the mic only if enabled AND the permission is held. Connect-screen redesign: - One scrollable Column (was a fixed centered layout that could clip with the new tab bar); host rows render via forEach (no nested LazyColumn). Colored section labels ("Saved hosts", "Discovered on the network", "Connect manually"), full-width host cards / fields / Connect button, a header + subtitle, and a muted footer. Verified live (emulator pf_phone -> home-worker-2): toggling mic requests RECORD_AUDIO; with it granted, a session sends mic frames (client "mic: sent=250 … peak=0.439" — real audio) and the host logs "client datagram stream ended … mic=276". Redesigned screen confirmed via screenshots. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-15 17:05:25 +02:00
