enricobuehler	890c7531d8	Merge branch 'midstream-resize': mid-stream resolution resize ... Lands the mid-stream resolution resize feature (client-driven Reconfigure so the host's virtual display + encoder follow a resized client window without a reconnect), all paths default OFF: - host hardening H1-H5 + session-binary Match window (C1) - Apple macOS/iPadOS Match-window trigger + settings (C3) and the resize overlay (blur + spinner) client UX - Windows on-glass fixes: corrective-ack actual resolution + pf-vdisplay monitor re-arrival for out-of-list mid-stream modes - Linux backend matrix + the live-reconfigure gate unit tests Validated on-glass: Windows IDD-push (.173), Linux Mutter + KWin. Android (C4) deferred; Apple full build pending on a Mac.	2026-07-11 15:59:07 +02:00
enricobuehler	e6fbcecdb9	fix(clients/windows): GUI text inputs read the live value, not a stale render snapshot ... A component() page re-renders reliably only when its props change: root wraps every screen in a stable animated border, so once the entrance tween settles the reconciler skips that unchanged-props subtree and a page's own use_state writes never force a re-render. Three text fields read their value at click time from that stranded local state: - PIN pairing sent an empty PIN, so pairing always failed with "wrong PIN, or not armed?" — the reported bug. The CLI --pair path bypasses the reactor and worked. - "Add host" Connect captured the empty mount-time address and silently did nothing (you open the modal precisely when the host isn't being discovered, so no discovery tick re-renders the page while you type). - Rename round-tripped the draft through an always-deferred AsyncSetState into a controlled text box, fighting the caret on fast typing and dropping the last character when Save was clicked before the write landed. Fix: hold each field's live value in a use_ref cell written on every keystroke and read at commit time (uncontrolled input), instead of a render-time snapshot. Rename is seeded when its target changes and no longer re-renders the whole page per keystroke. Reviewed the rest of the app (settings, speed test, library, stream, connect/request-access/waking, forget) — all driven by root-state props and wired correctly.

enricobuehler	f01c5e210c	feat(resize/apple): resize overlay — blur + spinner during mid-stream resize ... Make a Match-window resize deliberate instead of a stutter: blur the live stream and show a spinner while the host rebuilds its virtual display + encoder and VideoToolbox re-inits on the new-mode IDR. No new protocol — driven entirely by existing client signals. - ResizeIndicator (pure core, unit-tested): START = follower steering, END = a decoded frame at the target size, TIMEOUT = 2.5s safety net for a rejected/capped switch that never yields a new-size frame; re-arms only on a CHANGED target, not a repeated same-size drag. - MatchWindowFollower.onResizeTarget fires the instant the window differs from the live mode (deduped via lastSteered); a new onDecodedSize callback threads each new-mode IDR's coded dims through StreamPump/Stage2Pipeline → SessionPresenter → both stream views. - SessionModel gains @Published resizing (+ resizeTargeted/resizeDecoded, a tick on the 1 Hz stats timer, reset on disconnect); ContentView blurs the stream 16px and overlays ResizeIndicatorView while resizing (the 32px trust-prompt blur is unchanged and takes precedence). tvOS declares the props but never fires the follower (it drives modes via AVDisplayManager), so the overlay stays dormant there. Pure core verified on the Linux toolchain; full AppKit/UIKit build pending on a Mac. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-11 15:58:14 +02:00
enricobuehler	d294b3923c	test(resize): extract + unit-test the live-reconfigure gate (H1 gamescope / H5 per-client-mode) ... The Linux §6 on-glass matrix can validate the gamescope must-REJECT behavior only on native-gamescope hardware (the NVIDIA dev box fails headless GBM allocation — a nested Hyprland/sway/gamescope output comes up 0×0), so pin the gate down deterministically instead: extract the inline `live_reconfig_ok` decision into a pure `reconfig_allowed(compositor, per_client_mode)` and test it — gamescope rejects in every identity mode, a per-client-mode policy rejects on every backend, and all other compositors (plus the synthetic protocol-test source) with the default identity accept. Also fmt-normalizes the re_add block from the prior commit (whitespace only). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-11 14:56:59 +02:00
enricobuehler	4c18bb80ca	feat(resize/win): mid-stream resize on-glass fixes — corrective-ack actual res + monitor re-arrival ... On-glass validation on the .173 Windows IDD-push host confirmed the Reconfigure protocol + host rebuild work end-to-end and genuinely change pixels for an advertised mode (1920x1080 -> 1280x720: two SPS/IDR sets, ffprobe both res). It also surfaced two gaps for out-of-EDID-list target modes, both fixed here. Fix 2 (corrective ack carries the ACTUAL resolution): the H2/H3 corrective ack recovered only the achieved REFRESH (interval_hz), taking width/height straight from the request — so when a backend delivered a different RESOLUTION (Windows pf-vdisplay falling back to its advertised mode) the client was told it got a size it never received, and by the D2 discipline never re-asked. New `delivered_mode(frame.{w,h}, interval)` derives the ack from the captured frame's real dims (what the encoder opened at / the client decodes) in both the success and rollback branches. Unit-tested. Fix 1 (reach arbitrary mid-stream modes via monitor RE-ARRIVAL): the pf-vdisplay driver freezes a monitor's advertised mode list at IOCTL_ADD, and IddCx exposes no live update-modes DDI, so an in-place ChangeDisplaySettingsExW to a mode not advertised at arrival returns DISP_CHANGE_BADMODE. The manager's mid-stream reconfigure now REMOVEs + re-ADDs the driver monitor at the exact new mode, reusing the slot's stable per-client id (EDID serial / ContainerId) so the OS keeps identity + saved DPI. The rebuilt Monitor PRESERVES gen (lease/refcount continuity) and the group restore snapshot; reisolate_after_swap re-isolates the new target without recapturing it. Host-only — no driver change. One monitor hotplug per switch (the design's accepted "re-arrival for everything"). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-11 14:34:22 +02:00
enricobuehler	89ff326ebf	feat(resize/apple): Match-window mid-stream resize trigger + settings (C3) ... design/midstream-resolution-resize.md Phase 2, Apple client. The stream mode follows the session window/scene: a windowed macOS window resize or an iPad Stage Manager / Split View scene change renegotiates the host's virtual display + encoder via the existing PunktfunkConnection.requestMode, so a windowed session streams native-resolution pixels instead of scaling. Decode/present need nothing — VideoToolbox recreates its session on the keyframe-derived format-description change (§1 table). - MatchWindowFollower (new): the shared D2 trigger discipline — physical pixels even-floored + clamped ≥320×200, debounce to resize-end, ≥1 s between requests, skip a size equal to the live mode, request each distinct size at most once (stops re-asking a rejected size / looping on a host rollback). Pure normalize/request core is unit-tested (MatchWindowTests). - macOS StreamLayerView: fed from layoutPresenter() (bounds → convertToBacking), guarded to once-in-a-window. - iOS StreamViewController: fed from viewDidLayoutSubviews (bounds × render scale); iOS-only (iPhone fullscreen no-ops, tvOS uses AVDisplayManager). - Settings: "Match window" toggle in the Stream mode section (iOS + macOS), DefaultsKey.matchWindow, read per session by the follower. Verified on a Linux Swift 6.1.2 toolchain (the app target needs AppKit/UIKit, unavailable here): the real MatchWindowFollower.swift type-checks in Swift 5 mode against a connection stub, and the pure discipline + the follower's decision path pass a standalone harness (drag-settle + grow → exactly two switches, refresh preserved, no re-request loop). A full build + on-device run (macOS window, iPad Stage Manager) remains for a Mac. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-11 13:36:03 +02:00
enricobuehler	d0d9bd5bfb	feat(resize): mid-stream resolution resize — host hardening (H1–H5) + session-binary Match window (C1) ... design/midstream-resolution-resize.md Phase 0 + Phase 1. Host (Phase 0): - H1/H5: per-backend Reconfigure acceptance gate — reject for gamescope (all sub-modes; a resize must never relaunch the title) and under the per-client-mode identity policy (a resize would resolve a different display slot). Synthetic stays reconfigurable on purpose (the protocol test source; the C-ABI roundtrip test rides it). Plus a 500 ms host-side min-interval backstop against Reconfigure spam. - H2: rollback/corrective ack — the data plane reports the mode actually live after a failed rebuild (or a refresh the backend capped) through a reconfig_result channel; the control task forwards it as a second accepted Reconfigured so the client's mode slot self-corrects. - H3: live stats mode — SendStats reads a packed AtomicU64 (w|h|hz) updated on every switch instead of latching the session-start mode. - H4: registry::retire(gen) — a mode-switch rebuild force-releases the superseded Linux display, so linger/forever keep-alive policies don't accumulate kept monitors at stale modes. VirtualOutput carries pool_gen (fresh AND reused) and the Pipeline tuple threads it to the switch arm. Client (Phase 1, default off): - Settings: match_window policy + persisted last window size; exposed as the Resolution tri-state (Native / Match window / explicit) in the Skia console, GTK and WinUI settings pages. - pf-presenter: window opens at the persisted size; Hello mode follows the window's pixel size; D2 trigger discipline (400 ms debounce to resize-end, ≥1 s spacing, even-floor + ≥320×200 clamp, each distinct size requested at most once — covers rejects and host rollbacks) as a pure, unit-tested decision; HUD line + title refresh on a switch. - Session binary wires both --connect and --browse paths; the WinUI shell is session-always, so this covers Windows too. Verified: workspace tests + clippy green; synthetic --remode end-to-end; live session-binary run (window at persisted 1000×600 → Hello 1000×600@60). On-glass per-backend matrix (Mutter/KWin/gamescope-reject, keep-alive accumulation) still pending before any default flip.

enricobuehler	64b9d11ee6	fix(ci/windows): reclaim runner disk before building ... A full Windows CI pass writes ~50 GB of cargo target output into the shared C:\t (x64) / C:\t-a64 (arm64) scratch dirs on the intentionally-small (100 GB) windows-amd64 runner. Left to accumulate across runs, that overflowed the disk and every build died with "no space on device" (os error 112) — bytemuck_derive, cc, bindgen, windows, tracing-subscriber, fs4 all failing mid-compile, taking down pf-vdisplay/host builds. ensure-windows-toolchain.ps1 already runs first in every Windows job, so reclaim disk there before provisioning/building: call the runner-baked reclaimer (unom/infra installs C:\Users\Public\act-runner\clean-runner-disk.ps1 + a scheduled task) in threshold mode so THIS job starts with headroom regardless of when that task last ran, and keep incremental caches warm when there's room. A small inline fallback covers a runner not yet re-baked with the reclaimer. The whole step is best-effort — a cleanup hiccup never fails the build.

enricobuehler	ca61477c3c	docs(roadmap): surround 5.1/7.1 is shipped, not planned ... 5.1 and 7.1 surround now works end to end (host encodes multichannel via multistream Opus; native clients render >2 channels via AudioDec::Surround). Move it to Shipped + the at-a-glance table, and narrow the Planned entry to the genuinely-future object-based spatial audio work. Corrects the stale 'every path is stereo end to end / no client renders it yet' claim. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-11 11:26:48 +02:00
enricobuehler	68a1ec41c2	Merge pull request 'Rumble envelopes (0xCA v2) + 0.9.2' (#3) from rumble-envelopes into main	2026-07-11 01:35:01 +00:00
enricobuehler	4873e8925d	fix(apple/test): unwrap optional leaseSeconds in RumbleTuningTests ... RumbleTuning.leaseSeconds returns TimeInterval? (nil for the no-lease sentinel); XCTAssertEqual(_, _, accuracy:) needs a non-optional Double. Coalesce with .nan so a nil (which must not happen for a real ttl) still fails the assertion. Test-only — the production Swift built clean. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-11 03:16:56 +02:00
enricobuehler	01d10f46ea	chore(release): bump workspace version to 0.9.2 ... Release 0.9.2 — self-terminating rumble envelopes (0xCA v2) make "stuck rumble" inexpressible on the wire and retire the per-client staleness guesses, plus the Windows game-abandoned-residual stop and the Steam Deck Game-Mode HDR fix (bind gamescope's Wayland socket).

enricobuehler	73c911cae4	feat(rumble): host-authoritative self-terminating envelopes (0xCA v2) ... Rumble was level-triggered, unbounded state on a lossy channel: a non-zero level meant "buzz until further notice", healed only by the host re-sending state every 500 ms, and every client guessed when the host had died with its own magic timeout (SDL 1.5 s, Apple 1.6 s, Android up to 60 s). A lost stop, a reordered start, or a dead host could drone the motor for seconds. Make "stuck rumble" inexpressible on the wire. The 0xCA datagram grows a length-tolerant tail — [u8 seq][u16 ttl_ms] — so it self-terminates: the host authorizes a level for at most ttl_ms and renews it (~120 ms) while it holds, letting an abandoned one lapse client-side. seq is a per-pad wrapping reorder gate (reusing GamepadSnapshot::seq_newer) so a reordered stale start can't re-light a stopped motor. Decoders read the first 7 bytes as a plain level and ignore the tail, so no wire-version bump: an old client renders a new host's levels, and a new client falls back to its prior staleness heuristic against an old host (ttl = None). All four generation pairings render correctly. - core: encode_rumble_datagram_v2 / decode_rumble_envelope (datagram.rs); the client demux applies the seq gate then forwards (pad, low, high, Option<ttl>); next_rumble is unchanged (drops ttl), next_rumble_ttl keeps it; ABI adds punktfunk_connection_next_rumble2 + PUNKTFUNK_RUMBLE_NO_TTL, ABI_VERSION 4->5 (WIRE_VERSION unchanged — the tail is backward-compatible). - host (punktfunk1.rs): the flat 500 ms refresh becomes a renewal loop that bumps seq + stamps a fresh TTL on active pads and drains a short post-stop zero burst, then goes quiet. Hatches: PUNKTFUNK_RUMBLE_ENVELOPE=0 (legacy v1 + flat refresh, a bisect switch), PUNKTFUNK_RUMBLE_TTL_MS (clamped [150, 5000]). - renderers honor the TTL as their playback duration/deadline and keep their old heuristic only for a legacy (ttl=None) update: pf-client-core (the Deck haptic keep-alive is now deadline-bounded so it can't sustain a host-stopped rumble), clients/windows (SDL duration), android (JNI packs the lease out-of-band in bit 48 so any u16 ttl is unambiguous; Kotlin createOneShot(ttl)), apple (RumbleRenderer.envelopeDeadline + nextRumble2; sessionStaleSeconds demoted to the legacy fallback). - tests: codec round-trip + tail tolerance + seq-gate reorder (Rust); the probe asserts the v2 tail arrived under PUNKTFUNK_TEST_FEEDBACK; the Apple loopback asserts ttlMs round-trips end to end; RumbleTuning lease-decision cases. The host-side idle-timeout from the previous commit is defense in depth on the game side; this is the guarantee on the client side. Design: punktfunk-planning/design/rumble-envelope-plan.md.

enricobuehler	19e9828e8d	fix(host/windows): force off a stale rumble residual the game abandoned ... XInput vibration is level-triggered — it persists until the game sets it to zero — so a game that latches a rumble and then stops calling XInputSetState (a residual left at a menu/loading screen, or a plain forgotten stop) drones to the client forever (measured: a stuck (0,512) resent every 500 ms for 5.5 minutes). A real controller stops when the app stops driving it; mirror that. Keyed on game ACTIVITY (any SET_STATE, even an unchanged one), so a rumble the game keeps asserting is never cut — only an abandoned residual is; kept above SDL's ~2 s resend so an SDL-driven host game refreshes the activity clock before it fires. This is the game-facing half of the rumble-stop story; the wire-facing half is the self-terminating envelope model in the following commit. They compose: this bounds a game-abandoned rumble at the host, envelopes bound a host-abandoned rumble at the client. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-11 03:07:58 +02:00
enricobuehler	a1e79a0d69	fix(flatpak): bind gamescope's Wayland socket for Deck Game-Mode HDR ... The Vulkan-layer env vars alone left hdr10_format=None on a Deck OLED: the FROG gamescope WSI layer loads but must open a Wayland connection to gamescope's private socket ($GAMESCOPE_WAYLAND_DISPLAY = gamescope-0) to negotiate HDR10 via the gamescope_swapchain protocol. The Deck runs games as X11 clients, so --socket=wayland binds nothing and that socket never enters the sandbox → the layer silently can't reach the compositor → PQ tone-mapped to SDR, badge dark. Bind xdg-run/gamescope-0 (as chiaki-ng does); with the layer path + ENABLE_GAMESCOPE_WSI + the socket, the surface offers HDR10 and the presenter's existing HDR10 swapchain path engages — no client code change. Harmless off-Deck (the layer no-ops with no gamescope socket to bind). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-11 03:07:50 +02:00
enricobuehler	313f194c63	fix(ci/flatpak): the DNS failures are runner-load packet drops, not nsswitch — widen the retry budget ... Live-debugged on home-runner-1: confirmed the dnf install in Tooling does NOT actually rewrite /etc/nsswitch.conf (no authselect trigger fires), so the nss-resolve sed from 68b5376f/5f687a70 was never the actual fix. gitea-runner-fleet on this box is a shared, resource-capped fleet (3 replicas, --cpus 5/--memory 7g each, on 16c/24G) serving punktfunk AND several other orgs' repos concurrently. A push to main fans out ~8 punktfunk workflows at once on top of that other traffic, and the box's Docker embedded DNS resolver (127.0.0.11) drops UDP lookups under the combined load — exactly what retry.sh's own header already documented. Manually dispatching this job while the box was idle succeeded instantly, with or without the sed. retry.sh's 5-attempt (~100s) budget isn't always enough to outlast a synchronized multi-org burst; bumped the three flathub-facing calls (remote-add, install-deps-only, download-only) to 10 attempts (~9min). Verified end-to-end on a live re-run (run 8993) after this change: full success including publish + OSTree deploy. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>	2026-07-11 02:22:17 +02:00

enricobuehler	9e6bd790a3	feat(ci): accept deploy_host input so deploy-all can target a fresh box ...

enricobuehler	68b5376fb8	fix(ci/flatpak): reapply nss-resolve DNS fix after dnf pulls systemd upgrade ... The earlier fix (5f687a70) dropped `resolve` from nsswitch.conf before the Tooling step's dnf install. But that install pulls flatpak's recommended xdg-desktop-portal -> pipewire/wireplumber, which drags in a systemd package upgrade whose RPM trigger re-runs authselect and regenerates nsswitch.conf — silently re-adding the `resolve` entry and clobbering the fix before `flatpak remote-add` ever runs. Reapply the sed right after the dnf install, immediately before the first flatpak network call. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>	2026-07-11 01:40:03 +02:00
enricobuehler	35d97ae6ac	feat(windows): parallel virtual displays — proto v3 ring binding, manager slot map, group topology (W0–W3) ... design/windows-parallel-virtual-displays.md (display-management Stage 7 / §6.6): N simultaneously-live pf-vdisplay monitors, one sealed ring each, every idd-push-security invariant preserved per-ring. - proto v3: SharedHeader._pad → target_id — the ring NAMES its monitor, host-stamped before the magic; the driver publisher refuses a cross-bound ring via the shared, unit-tested frame::check_attach (new DRV_STATUS_BIND_FAIL — the gamepad pad_index validation applied to frames, invariant #10); the host's wait_for_attach surfaces the refusal loudly and self-checks its own stamp. - manager: the one-monitor MgrState becomes a slot map keyed by the client's identity slot (0 = anonymous/GameStream); per-slot reconnect + dead-WUDFHost preempts, slot-scoped begin_idd_setup (a different identity is an admission question, never a preempt), ONE device-level watchdog pinger, per-slot /display/state + /display/release. - group topology: isolate_displays_ccd takes the managed target SET (a sibling slot is never deactivated); SavedConfig + the DDC/PnP axes move to the group record (first-in captures, last-out restores); desktop layout via CCD source origins from the pure layout::arrange (auto-row default, manual pins win), re-applied on create + reconfigure. - admission: the Windows separate→reject override now sits behind the PUNKTFUNK_WIN_SEPARATE=1 validation hatch (the wedge it guarded is structurally gone — a second identity gets its own monitor + ring; default flips in W5 after soak); max_displays and NVENC session-unit budgets decline an unaffordable display AT admission; kick_dwm_compose is process-globally throttled and per-display — cursor jump + 35 ms dwell (a sub-tick jump composes nothing; DWM reads dirties from current state at the next vsync tick). On-glass on the RTX box: V1/V2/V4/V5/V6/V9 green — two paired clients on two monitors streaming ~60 fps each with zero mismatches and zero bind failures, churn-hammer clean (no 0x80070490), per-ring mode-change recreate leaves the sibling untouched, typed budget rejection, fault-injected cross-bind refused loudly with the sibling undisturbed. V7: WUDFHost-kill shared fate is clean; in-process device recovery is a known follow-up (the retired-never-closed control handles block the adapter cycle — reset-pf-vdisplay.ps1 recovers). DWM composes two IDD monitors concurrently at 60 fps — the plan's load-bearing unknown, answered yes. Also carries the client-HDR EDID forwarding that shared this working tree (Hello::display_hdr → AddRequest luminance tail → the monitor's CTA-861.3 HDR block, PUNKTFUNK_CLIENT_PEAK_NITS hatch) and the Deck client fixes (40 ms rumble keep-alive with 1-LSB jitter, HDR self-diagnosing presenter warn, flatpak HDR env).

enricobuehler	3078528b28	feat(video): 4:4:4 defaults — the host allows it, the client chooses it ... Capability now lives on the host, choice on the client. PUNKTFUNK_444 flips to DEFAULT ON with an explicit-off grammar (0/false/off/no — the old presence-only flag() would have read =0 as on); every existing gate still applies (client advertisement, HEVC, full-chroma capture, encode probe, Windows HDR-display downgrade), so an unset host merely stops refusing. The Apple client's "Full chroma (4:4:4)" toggle flips to DEFAULT OFF: full chroma is a per-session trade — a clear win for desktop/text, but at a fixed bitrate game content spends those bits better at 4:2:0, and the encode/decode pixel rate rises. Persisted user choices survive both flips. Live-verified on the CachyOS VM: host with no env negotiates chroma_format_idc=3 for a 4:4:4-advertising client; PUNKTFUNK_444=0 resolves 4:2:0.

enricobuehler	0dacb37088	feat(linux): zero-copy 4:4:4 — the EGL worker converts to planar YUV444 on the GPU ... A 4:4:4 session no longer falls to the CPU path (SHM capture + swscale RGB→YUV444P + re-upload — the fps-ceiling triple tax). The zero-copy worker grows a Yuv444Blit: three full-res R8 GL passes (the proven BT.709 coefficients; studio or full range per PUNKTFUNK_444_FULLRANGE, read by both processes so pixels and VUI flip together) into ONE stacked 3-plane pitched CUDA allocation — which keeps the worker↔host wire and IPC single-plane. The encoder copies the planes into ffmpeg's yuv444p CUDA surface and hevc_nvenc emits Range-Extensions 4:4:4 natively. ImportKind::Tiled444 is APPENDED to the worker protocol (a worker outliving a replaced host binary must keep the old tags stable; an old worker just errors the import, which the fail machinery already handles). A 4:4:4 session on a LINEAR/gamescope capture — no convert wired there — fails with a clear message instead of letting hevc_nvenc silently subsample. caps().chroma_444 now keys off the session (it missed the GPU path when keyed off the swscale's existence). Live-verified on the CachyOS VM (RTX 5070 Ti): per-frame "imported to CUDA yuv444=true", stream Rext/yuv444p/bt709 in both tv and pc range, no CPU-path warning.

enricobuehler	5f687a7083	fix(ci/flatpak): drop nss-resolve so flatpak can resolve DNS in the container ... fedora:43 nsswitch routes host lookups through the resolve module (systemd-resolved), absent in a CI container. git/curl/dnf fall through to the dns module (Docker 127.0.0.11); flatpak/ostree's resolver trips [!UNAVAIL=return] and dies with '[6] Could not resolve hostname'. Was masked as flaky 'busy runner drops DNS' + retry.sh, but it's deterministic on runners where the resolve module tips that way (started failing when jobs landed on the newly-added home-runner-2). Drop the resolve entry -> plain dns lookups. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-10 18:03:43 +02:00

enricobuehler	3ba19f28a2	feat(apple): the gamepad UI comes to tvOS - focus-driven, with real session controls ... The console UI now runs on tvOS through the NATIVE focus engine: carousel cards and settings rows are focusable Buttons (Siri Remote and pads both navigate; imperative scrollTo replaces the drop-prone scrollPosition binding), while iOS/macOS keep the 60 Hz poll untouched - on tvOS it carries only what focus has no concept of: X/Y screen actions and left/right value adjust with the poll's dominant-axis feel (onMoveCommand proved input-source-dependent: keyboard intercepted, pad dpad not -> double steps). Text entry uses the system fullscreen keyboard (TVTextEntry); pairing + library present as covers under the launcher; the game library defaults ON; settings values slide a quiet 14 pt in the step's direction. Session controls: controller/remote input routes EXCLUSIVELY through GameController during a stream (GCEventViewController, interaction disabled) - a pad's B no longer doubles as a UIKit menu press that ended sessions mid-game. Deliberate exits only: the cross-client escape chord (hold L1+R1+Start+Select 1.5 s - pf-client-core's contract, now implemented on all Apple platforms) and holding the remote's Back >= 1 s; the start-of-stream banner (now also on tvOS) teaches both. The Siri Remote's touch surface drives the host pointer - press = left click, Play/Pause = right click, release-tail jumps gated so motion stays truly relative. tvOS 26 regressions fixed at the root: the app-wide brand tint rendered every unfocused control as a blank pill (tint dropped on tvOS) and the 17 pt root font shrank the whole platform (29 pt there), plus 10-foot sizing across host cards, the gamepad screens, and the stats HUD (whose misleading "Press Menu" hint is gone). Acknowledgements scrolls by focus-sized chunks and Menu pops instead of suspending; full-width focusSections make the home actions reachable from any column. The presenter defaults to stage-3 glass pacing on tvOS (a 60 Hz panel fed a 60 fps stream is the sticky-FIFO worst case behind the 50 ms display stage) and is pickable from the gamepad settings; HDR capability advertises from AVPlayer.eligibleForHDRPlayback instead of the current mode's EDR headroom, so an SDR home screen no longer hides an HDR TV.

enricobuehler	1fcf9e11ec	fix(video): honor the signaled CSC matrix end-to-end + tvOS HDR presentation ... Clients derive Y'CbCr->RGB from the stream's SIGNALED matrix x range x depth via shared csc rows (Rust csc_rows + Swift CscRows) instead of hardcoded 709/2020 - a BT.601-signaled stream (a Linux host's RGB-input NVENC) no longer renders with a constant hue error. Host-side signaling made honest across NVENC/VAAPI/openh264/GameStream and the session plan's chroma/bit-depth. Decoded color-bar fixtures (601/709 x limited/full) pin the math in tests on both cores. Same presenter, tvOS HDR: tvOS has no Metal EDR API and a bare PQ colorspace tag composites UNTONE-MAPPED (the "overblown" Apple TV report), so HDR now splits on the display's live EDR headroom - PQ passthrough when the per-session AVDisplayManager mode switch landed (a real HDR10 output tone-maps itself), else an in-shader PQ->SDR tone-map (203-nit reference white, extended-Reinhard 1000-nit knee, 2020->709) into the proven SDR layer config.

enricobuehler	a011aebef5	feat(host,web): experimental PnP monitor-devnode disable for Exclusive sessions ... Second experiment against the connected-but-dark-head stutter (field-proven on the reporter's box: unplugging his standby HDMI TV removes a metronomic ~4 s double-jolt; DDC/CI is a dead end for TVs — measured on the lab LG, VCP 0xD6 gets no I2C ACK). An Exclusive isolate only removes physical monitors from the CCD topology; their PnP devnodes stay live, so every standby wake (auto input scan, Instant-On HPD cycling) still triggers the full Windows reaction: PnP arrival/removal, CCD re-evaluation, DWM invalidation — the suspected hiccup mechanism (Apollo #368's Device-Manager-refresh signature). - New `pnp_disable_monitors` display-policy axis (default off): orthogonal to presets like game_session/ddc_power_off, surfaced in GET/PUT /display/settings + the enforced list, carried through the layout transform. - windows/monitor_devnode.rs: after the isolate takes, disable exactly the deactivated monitors' devnodes — CCD target → monitor device path (DISPLAYCONFIG_TARGET_DEVICE_NAME) → PnP instance id → CM_Disable_DevNode with CM_DISABLE_PERSIST, so a hot-plug RE-ARRIVAL stays disabled (that persistence is the whole point). Teardown re-enables BEFORE the CCD restore (+300 ms re-arrival settle) so restored paths have their monitors back. Precise selection — co-installed third-party virtual displays are never touched. - Crash safety: instance ids journal to <config>/pnp-disabled-monitors.json before disabling; serve startup re-enables leftovers from a crashed host. Worst case is documented in the console help (Device Manager re-enable). - Web console: second Experimental-badged toggle (the DDC block refactored into a shared ExperimentalToggle), EN/DE strings, preset-switch carry. Verified: Linux 263 tests + clippy + fmt clean; Windows (RTX box) 220/220 + clippy clean; web tsc + production build clean; openapi.json regenerated.

enricobuehler	d1770c3476	refactor(host): shared send-pacing policy for the native and GameStream video planes ... Networking-audit deferred plan §5. Both planes spread a frame's wire packets across a time budget in chunked bursts; the schedule logic, PUNKTFUNK_VIDEO_DROP loss injection, and percentile helper were duplicated between punktfunk1::paced_submit and gamestream::stream::spawn_sender. Now one host-local send_pacing::pace_frame carries the policy; each plane keeps its exact historical parameterization and its own syscall layer (GSO Session vs sendmmsg over the RTP socket — policy shared, plumbing not): native burst_bytes = PUNKTFUNK_PACE_BURST_KB (microburst stage), fixed 16-packet chunks, budget = 0.9 × time-to-deadline gamestream no burst stage, bounded steps (≤ 12, chunk ≥ 16, the old pace_layout), fixed budget = 0.75 × frame interval Deterministic-schedule unit tests pin both parameterizations against verbatim transcriptions of the legacy math (burst split, chunk layout, step counts — including pace_layout's historical test anchors) and the sleep-target formula (GameStream's legacy per_step form agrees to ≤ steps/2 ns; the unified fraction form is used for both). Deliberate sub-observable normalizations, all on test-knob or ns-scale paths: PUNKTFUNK_VIDEO_DROP is now parsed once per process and clamped to 1..=90 on the GameStream plane too (was per-stream, unclamped), and the native sleep floor comparison is now >= (was >, differs only at exactly 500 µs). Validation: - 263 host tests green, incl. the end-to-end sender_delivers_batches (spawn_sender → pace_frame → sendmmsg, byte-identical delivery) - PUNKTFUNK_VIDEO_DROP FEC sweep at 5 % and 8 % injected wire loss: all 11 punktfunk1 integration tests (full host↔client roundtrips through send_loop → paced_submit) recover and pass - pending: one real Moonlight smoke session against this build (the legacy-plane timing gate) — recipe handed to the operator Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-10 16:26:41 +02:00

enricobuehler	ddb93c533c	fix(core,android): networking-audit small follow-ups — bounds, oversized AUs, probe flag ... Networking-audit deferred plan §6: - 6.1 client reassembler ceiling derived from the negotiated rate: Welcome::session_config (client role) now sets max_frame_bytes to clamp(4 × bitrate_kbps×125 / refresh_hz, 8 MiB, 64 MiB) instead of the blanket 64 MiB p1_defaults bound — the hostile-header memory ceiling was ~10× larger than any real access unit. Local only (the host never reassembles video; the wire is self-describing); a bitrate-0 (older) host keeps the old bound. Unit-tested floor/derived/host/old-host cases. - 6.2 ProbeState.active is cleared when the host's ProbeResult lands, so the pump stops mirroring receive counters once the burst is over. - 6.3 Android: an AU larger than the codec input buffer is DROPPED with a recovery-keyframe request and a counter, on both the sync (feed) and async (feed_ready) paths — a truncated AU is corrupt input the decoder chews on silently, poisoning the reference chain until the next IDR. The async path recycles the never-queued input slot; the sync path returns the dequeued slot with zero valid bytes. - 6.4 bounded uplink channels: mic_tx at 64 (~320 ms of 5 ms frames; overflow sheds the fresh frame with a debug log — a tokio mpsc can't shed from the head, and past 320 ms of backlog the mic is broken either way; the bound is about memory) and ctrl_tx at 32 (sparse requests; a full queue means a wedged control task, reported as Closed). input_tx stays unbounded per the plan: keyboard/mouse events must never silently drop, and gamepad state is snapshot-healed. - 6.5 (wire version byte says P1 while streaming Gf16): record-only, resolves with the P2 packet revision. include/punktfunk_core.h: cbindgen re-emitted in the new module order after the quic/ split (item 3) — no semantic change beyond the reorder. cargo ndk check (arm64-v8a), workspace clippy, core+host tests green.

enricobuehler	9afcbcd307	feat(transport): Windows DSCP via qWAVE flows — PUNKTFUNK_DSCP now real on the wire there ... Networking-audit deferred plan §4 (the qos.rs follow-up). On Windows set_tos_v4 succeeds but the stack strips the mark without a qWAVE flow, so PUNKTFUNK_DSCP=1 was a silent wire no-op there. Now (Apollo/Sunshine's approach): QOSCreateHandle once per process; QOSAddSocketToFlow per connected media socket — video → QOSTrafficTypeAudioVideo, audio → QOSTrafficTypeVoice (QOS_NON_ADAPTIVE_FLOW) — then best-effort QOSSetFlow(QOSSetOutgoingDSCPValue, 40/48) to pin the exact CS5/CS6 the other platforms mark. The pin lands for elevated processes (the host runs as the SYSTEM service — exactly where the video egress is) or under the "allow non-admin DSCP" policy; otherwise the traffic-type default marking stands (still WMM-useful). Gating + contract unchanged: opt-in via dscp_enabled(), every step debug-logs and continues. set_media_qos now returns an RAII QosFlow guard (QOSRemoveSocketFromFlow on drop) that must outlive the socket's traffic: stored in UdpTransport (declared before the socket, so drop order removes the flow first) and held for the stream's scope by the GameStream video/audio senders — whose tagging moved after connect(), since qWAVE derives the flow's 5-tuple from the connected socket (behavior-neutral on Linux). Off-Windows the guard is inert and never constructed. Validated: cargo check -p punktfunk-core --target x86_64-pc-windows-msvc green (the full host can't cross-check from Linux — aws-lc-sys needs MSVC tooling; it builds on-box via deploy-host.ps1). Remaining on the next Windows pass per plan: deploy to the RTX box and pktmon/Wireshark the client side — DSCP ≠ 0 on video egress with PUNKTFUNK_DSCP=1, 0 without.

enricobuehler	d4467a44e2	feat(core): mid-stream clock re-sync — live offset survives wall-clock steps and drift ... Networking-audit deferred plan §2. The host↔client offset was measured once at connect; an NTP step or slow drift silently corrupted the clock-based jump-to-live signal, the ABR one-way-delay signal, and every latency stat — 4a3b1ae2's disarm backstop stopped the IDR storm but lost the detector for the session. Now the client re-estimates mid-stream and recovers it. - quic: ClockResync — the connect-time 8-round probe/echo estimate as a select!-driven state machine (rounds matched by echoed t1, stale batches ignored), plus accept_resync (batch min-RTT ≤ max(2 ms, 1.5× connect RTT) so a congested window can never bias the offset). No wire change: the host has always answered ClockProbe at any time on the control stream. - client: the offset lives in an Arc<AtomicI64> seeded at connect; the control task re-probes every 60 s and immediately after the pump's FIRST no-op clock flush (the "clock stepped under me" signal, sent on the next report tick). On apply: store, reset stale_frames/noop_clock_flushes, re-arm the clock detector if a step had disarmed it. The disarm heuristic stays as the final backstop. Public NativeClient::clock_offset_ns keeps the connect-time value (ABI untouched); new clock_offset_now_ns() / clock_offset_shared() expose the live value. - consumers migrated to the live offset: pf-client-core session stats, the pf-presenter e2e stamp, Windows session/render, Android feeder/drain/ DisplayTracker (the tracker holds the shared handle, not the client, so the leaked render-callback refcount can't pin the session). - probe: --clock-resync runs a second full handshake mid-connection and asserts a sane, consistent estimate. Live against the local canary host: offsets 8646/2139 ns, disagreement 6 µs, 8/8 rounds — OK. Unit tests cover the round collection, stale-echo rejection, batch restart, min-RTT selection, and the acceptance guard. cargo ndk check green. Remaining manual validation: `sudo date -s "+2 sec"` on a live streaming client → expect one no-op flush, a re-sync, re-armed detector, no IDR pulse.

enricobuehler	68a863866a	perf(core): packetize straight into the wire pool — zero-alloc host send path ... Stage B of the zero-copy host packetize path (networking-audit deferred plan §1): Packetizer::packetize_each yields (header, shard) pairs in exact wire order; Session::seal_frame writes seq(8) ‖ header(40) ‖ shard ‖ tag scratch directly into the pooled wire buffer and seals [8..] in place. The per-packet intermediate Vec (header ++ body) and its extra memcpy are gone — with Stage A, every data byte is now copied once (frame → wire) instead of three times, and the ~2 transient allocs/packet on the send thread are zero after pool warmup (~180k allocs/s at 1 Gbps rates). packetize() stays as a thin wrapper over packetize_each — the reference implementation used by tests and the loss harness. - wire-equivalence test: pooled path vs wrapper path byte-identical across multi-block/partial-tail/exact-multiple/empty frames, fec 0%/50%, both schemes, crypto on/off - loss-harness sweep: recovery rates identical to the pre-item-1 baseline - bench pipeline (end-to-end incl. client half) vs pre-item-1 baseline, stages A+B cumulative: gf16/64K -3.6%, gf16/1M -3.2%; gf8 cases are Cauchy-math-bound and unchanged within noise - cargo ndk check (arm64-v8a) green Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-10 15:22:53 +02:00

Only the frame's final (possibly partial) shard is staged in a reusable zero-padded scratch; blocks are consecutive shard ranges, so every other shard is a full payload-sized slice. - gf8: encode_sep() over the same Cauchy codec — parity byte-identical to nanors/Moonlight (nanors_exact_parity_vectors unchanged and green) - gf16: reed_solomon_simd::encode is already generic over AsRef<[u8]> - loss-harness sweep: recovery rates identical before/after - bench pipeline (end-to-end, host+client): gf8/64K -3.0%, gf16/64K -2.2%, gf16/1M -3.4%, gf8/1M -0.7% Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-10 15:16:07 +02:00

Every session sealed with the literal salt b"pkf1", so GCM nonce uniqueness (nonce = salt || sequence) rested ENTIRELY on the per-session key being fresh — correct today, but a single key-reuse bug anywhere in the handshake path would have meant immediate catastrophic nonce reuse instead of merely a wrong key. Random salt per session keeps the documented second line of defense real. The salt is negotiated via Welcome, so every deployed client just follows — no wire or compat change.

enricobuehler	6fbab53d56	feat(audio): libopus packet-loss concealment on the client audio plane ... The 0xC9 audio datagrams ride the lossy plane with no FEC, and no client ever consulted the per-packet sequence: a lost 5 ms Opus packet played out as a hard gap in the ring — an audible click/pop on every drop, i.e. constantly on the Wi-Fi links where video loss is already being FEC-absorbed. Now a shared `AudioGapTracker` (punktfunk-core::audio — pure data, wrap-safe, unit-tested incl. u32 wraparound / reorder / duplicate cases) tells the decoder how many packets went missing immediately before each received one, and both native clients (pf-client-core PipeWire path, Android AAudio path) synthesize that many frames of libopus packet-loss concealment first: `decode` with empty input (the opus crate maps it to a NULL data pointer = PLC), sized by the last real frame's sample count. Interpolated fade instead of a click. Bounds: a gap is capped at 10 packets (50 ms) — libopus PLC fades to silence after a few frames anyway, so past the cap the rings' existing underrun/re-prime path takes over. Reorders and duplicates conceal nothing (the plane has no reorder buffer; playing a late packet where it lands is the existing behaviour). In-band Opus FEC (LBRR) is deliberately NOT used: the host sends 5 ms frames and LBRR needs ≥10 ms frames to carry anything. The cap is a crate-private const so cbindgen keeps it out of the C ABI header. Host cargo tests + clippy green; android crate verified via cargo ndk check.

enricobuehler	4a3b1ae2e3	fix(core): jump-to-live survives a mid-session clock step — disarm on no-op flushes ... The clock-based jump-to-live detector compares wall-clock receive time against the CONNECT-TIME skew offset. A wall-clock step on either end (NTP mid-session, resume-from-sleep correction) shifts every future frame's apparent latency by a constant: past the 400 ms bound the detector fires forever — one backlog flush + recovery IDR every 2 s cooldown, and the bitrate controller rides the repeated "flushed" bad windows down to its floor. A stream that was perfectly live turns into a periodic quality pulse with no recovery path. The tell is in the flush itself: a genuine 400 ms backlog is ≥~170 datagrams even at the 5 Mbps bitrate floor, but a clock-step flush finds nothing to discard. So: two consecutive clock-triggered flushes that discarded <64 datagrams and zero queued AUs disarm the clock detector for the session (logged). This also covers upstream router bufferbloat — delay standing in a queue a local flush can't drain, where the OWD signal to the bitrate controller is the actual remedy and a 2 s IDR cadence only feeds the congestion. The clock-free queue-depth detector stays armed either way; it measures the local queue directly and can't be fooled by a clock. Rode along: the 11-field `Negotiated` tuple is now a documented struct — the connect/worker plumbing reads as named fields instead of positional magic.

enricobuehler	c7b8007ce7	fix(core): receive path — replay window covers the loss window, zero-alloc open ... Two receive-path findings from the networking audit: 1. The anti-replay window (4096 seqs) silently re-tightened the "late ≠ lost" fix: at 1 Gbps (~125k pkt/s) it spans only ~33 ms, so a Wi-Fi-retry-delayed shard the reassembler's 120 ms loss window would still use was dropped HERE first as "older than the window" — recreating the false-loss → recovery-IDR churn the time-based loss window was built to kill, exactly on the high-rate links punktfunk targets. Widened to 32768 (covers 120 ms up to ~270k pkt/s, ≈2 Gbps+); the bitmap costs 4 KiB per session and the replay-hiding bound stays finite. 2. Every received datagram still paid one Vec allocation in the AES-GCM open (and a to_vec on the plaintext probe path) — ~125k allocs/s of cross-thread allocator churn at line rate, the same class of overhead that was the documented single-core wall on the macOS receive path. New `SessionCrypto::open_in_place` (mirror of seal_in_place; GCM verifies the tag BEFORE decrypting, so a forged packet never yields plaintext) lets `poll_frame` decrypt inside the recv ring and hand the reassembler a slice. Byte-identical semantics, unit-tested against `open` incl. tamper/runt cases; criterion entry added next to seal_in_place. Tests: 94 core unit + loopback/c_abi suites green; clippy clean.

enricobuehler	cca5008805	feat(host,web): experimental DDC/CI monitor power-off for Exclusive sessions ... The sole-virtual-display stutter investigation's active experiment: when the Exclusive isolate deactivates a physical monitor, the dark-but-connected head keeps getting serviced (monitor standby auto-input-scan / DP link churn) at a seconds-scale cadence — the leading suspect for the periodic double-jolt. A panel commanded off over DDC/CI (the VESA monitor-control channel in the video cable) believes it has an owner and, on cooperating firmware, stops probing. - New `ddc_power_off` display-policy axis (default off): orthogonal to presets like game_session, stored in display-settings.json, surfaced in GET/PUT /display/settings + the enforced list, carried through the layout transform. - windows/ddc.rs: VCP 0xD6 power-mode control via the dxva2 Physical Monitor API. Deliberately DPMS-off (0x04, DDC stays responsive, signal return wakes) and never power-button-off (0x05, bricks-until-button on many monitors). Probe-before-write; every failure is skip-and-log — monitors without DDC/CI, OSD-disabled, or behind docks/KVMs degrade to a logged no-op. - Manager wiring: panels commanded off immediately BEFORE the Exclusive CCD isolate (an HMONITOR — and with it the DDC channel — only exists while the display is active); teardown wakes them right after the CCD restore, where returning signal alone already wakes most firmware. - Web console: an Experimental-badged on/off control on the display card, applied immediately like the game-session axis and preserved across preset switches; EN/DE strings incl. the wake-failure escape hatch (press the monitor's power button once, turn the option off). Diagnostic value on top of the fix: if this kills a reporter's stutter, the churn is monitor-firmware-initiated; if only topology=primary/extend does, the driver services dark heads regardless — the two remaining root-cause classes. Verified: Linux 258 tests + clippy + fmt clean; Windows (RTX box) 220/220 + clippy clean; web tsc + production build clean; openapi.json regenerated.

enricobuehler	f68f6bc590	fix(linux): zerocopy worker survives the host binary being replaced on disk ... A pacman canary upgrade under a running host (0.5284→0.5338, 09:24 today) unlinked /usr/bin/punktfunk-host; current_exe() then readlinked to "<path> (deleted)", every worker spawn failed ENOENT, and each session silently fell back to the CPU linear-copy capture — observed as the box "regressing" to ~90 fps at 5-7 MP until a service restart. - RemoteImporter::spawn now pins a read fd to /proc/self/exe (once, kept for the process lifetime) and execs the worker via /proc/self/fd/<n>. The magic link names the running image's inode, not its path, so the spawn survives replacement/deletion — and the worker is always byte-for-byte the host's own build, so a mid-upgrade spawn can't hit a worker-protocol skew either. If the fd draws number 3 (the worker's socket slot — the pre-exec dup2 would clobber it) it is re-numbered; if /proc is unavailable the old path-based spawn remains as fallback. - argv[0] is set to "punktfunk-host" and the worker prctl-renames its comm to "pf-zerocopy" — exec-by-fd-path would otherwise show a bare fd number in ps and top. - zerocopy-probe now also spawns the worker (handshake + modifier query), so the probe catches spawn-level breakage, not just FFI/GPU bring-up. Verified end-to-end on the dev box: probe with the binary unlinked mid-run (/proc/self/exe → "(deleted)") still spawns the worker and reports all 13 modifiers. New unit tests cover the pinned spawn and the deleted-file exec; the latter retries ETXTBSY (fs::copy's write fd leaks into other tests' forked children until their execs clear it — a copy-then-exec harness artifact, not a production concern).

enricobuehler	7ab97bb1a3	feat(host): capture-stall watch — DWM-level self-diagnosis for the Exclusive-topology stutter ... Field repro (Mounjay, still present on 0.9.0): the ~4 s double-jolt stutter appears ONLY while the virtual display is the sole active display (Exclusive topology) and stops the instant Windows switches to Extend — live, both ways. Cross-project research (Apollo #179/#358/#368/#563/#776, VDD #36, Tom's HW) points at the display/present path BELOW capture: an inactive-but-connected DisplayPort head being periodically serviced (standby HPD/AUX/link events), with a DWM software-vsync clock beat as the secondary (different-signature) class. Neither ends in anything our recovery-side detector can see unless the client actually loses data — so give the HOST a direct sensor at the ring: - StallWatch (idd_push.rs): a >150 ms hole in DWM frame delivery counts as a capture stall only when the 8 preceding frames arrived within 400 ms — sustained >=20 fps flow, so an idle desktop, a caret blink, or a paused video can never trip it. Per-stall debug line; when stalls settle into an evenly-spaced multi-second cycle, one rate-limited WARN names the class: 'capture stalls are METRONOMIC', with the topology=primary/extend and refresh-rate leads. Ring-recreate recovery gaps reset the watch (self- inflicted, already logged by the recreate path). - The evenly-spaced-cycle detector moves out of punktfunk1.rs into metronome.rs (RecoveryCadence -> Metronome, unchanged logic + tests) so the IDR-serve detector and the stall watch share one implementation; the recovery WARN now cross-references the capture-stall lines. Diagnosis map for an Exclusive-mode stutter log: 'slow display-descriptor poll' = something holds the win32k display lock; 'capture stalls are METRONOMIC' without it = DWM stopped composing (DP servicing / present clock, below us); recovery-IDR METRONOMIC alone = frames flowed but clients lost data. Verified: Linux tests+clippy+fmt clean; Windows (RTX box) 220/220 + clippy clean. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-10 11:05:21 +02:00
enricobuehler	aaed4380e5	chore(release): bump workspace version to 0.9.1 ... Release 0.9.1 — a patch release led by three field-reported crash/brick fixes, a security-review hardening pass, and the tiered stats overlay landing on every platform. The regression that forces the release: 0.9.0's stats-HUD display stage hard-linked an API-33 NDK symbol believed API-26, so the native library failed to load on every Android < 13 device — "Identity unavailable: …NativeBridge", dead pair button, no discovery. The callback is now dlsym-resolved (pre-13 devices simply lose that one HUD row), and a new CI guard fails the APK build if the native lib ever imports a symbol beyond the API-28 floor. Two more crash-class host fixes ride along. GNOME: one console Approve admitted every parked knock a retrying client had stacked up — three instant Mutter virtual monitors segfaulted gnome-shell down to the GDM greeter; knock generations now admit exactly one, Mutter topology mutations are serialized process-wide, stale session-env is cleared, and an opt-in PUNKTFUNK_RECOVER_SESSION_CMD hook can revive a dead session on the next connect. Windows: twin identical GPUs died in a TEX_FAIL retry loop when the IDD-push ring opened on the wrong twin — the ring now rebinds once onto the render LUID the driver reports, and GPU inventory ordering is LUID-sorted and stable for the boot. Input: held gamepad state is rock-solid — Android pins one qualified pad device (motion-sensor siblings zeroed axes on every event interleave), and pad state now travels as sequence-gated idempotent snapshots (HOST_CAP_GAMEPAD_STATE, negotiated; either end older falls back to the per-transition path). Security review findings addressed: sliding-window anti-replay on the AEAD-authenticated data-plane sequence, 0600 client key + 0700 config dir (existing stores re-locked), the web console's post-login open redirect closed, the Windows installer's FFmpeg DLLs SHA-256-pinned, and a fork guard on PR jobs sharing signing-runner labels. Features: the 3-tier stats overlay (Compact/Normal/Detailed) ships on every platform with cycle shortcuts and settings pickers; Apple gains the experimental stage-3 glass-gated presenter (fixes the hidden 29-30 ms display-stage queue on 120 Hz ProMotion; stage 2 stays default) and a morphing, device-corner-concentric overlay card. Plus repo-wide docs sync and the flatpak CI network hardening. The [workspace.package] version (inherited by every crate via version.workspace) is the release being cut; the 14 workspace entries in Cargo.lock and the api/openapi.json info.version are refreshed to match (CI builds --locked). Canary derives from the tag as minor+1 of the latest stable. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> v0.9.1	2026-07-10 10:49:10 +02:00
enricobuehler	3d6c06bb06	fix(ci): flatpak job rides out the runner's network flake — retry every single-shot fetch ... The flatpak run dies most pushes at `flatpak remote-add` with an instant "[6] Could not resolve hostname" (runs 8755/8702/8689), 25ms after dnf pulled 329 packages fine — and deploy-docs separately hits "dial tcp: i/o timeout" to unom-1 (8716/8679). The busy runner drops UDP DNS + TCP dials under parallel-job load; tools with built-in retries (dnf) ride it out, single-shot fetches killed the whole 2h build slot. * scripts/ci/retry.sh: linear-backoff wrapper (5 tries, attempt*10s); stdout passes through untouched so $(…) capture works. * Tooling: retry the flathub remote-add. * Build split: a retried prefetch phase (--install-deps-only, then --download-only for every crate in cargo-sources.json) warms the state dir; the long compile then runs with no network left to flake on. * Seed step: probe (retried) whether the server repo exists — ONLY first publish may continue fresh. The old blanket `rsync || warn` swallowed transient failures too, producing the single-branch summary that clobbers the other channel (the exact bug the step's comment documents). * Deploy: retry the idempotent ssh/rsync calls to unom-1. * raw.githubusercontent curl: --retry 5 --retry-all-errors. docker.yml's deploy-docs has the same disease but sits on drone-ssh; left for a follow-up. Real root cause is runner-host networking (conntrack / upstream DNS under burst load) — retries make the jobs indifferent to it.

enricobuehler	f5e5297a2a	style: cargo fmt — settle comment/assert layout the last two fixes left unformatted ... `cargo fmt --all --check` on main flags decode.rs (android dlsym fix), probe/main.rs (0600 key fix), and session.rs (anti-replay tests). The probe one is restructured rather than machine-formatted: rustfmt wanted the key- permissions comment gutter-aligned to the trailing `// the certificate is public` comment, so fold both into one block comment above the write instead.
