enricobuehler	6f77574876	feat(host/vdisplay): per-connect active-session backend selection ... Bazzite/SteamOS boxes flip between Steam Gaming Mode (gamescope) and a KDE/GNOME desktop. The host statically read PUNKTFUNK_COMPOSITOR / XDG_CURRENT_DESKTOP once, so switching to Desktop Mode failed the stream, and the gamescope managed-session path stopped+relaunched the autologin per connect — leaking GPU context on F44 (reconnect → black screen). Replace the static read with a runtime probe of the live session and route each connect to the right backend, churn-free: - vdisplay::detect_active_session() probes /proc for the running compositor of our uid (gamescope|kwin_wayland|gnome-shell|sway, desktop outranks a leftover gamescope) + scans the runtime dir for the live wayland-* socket. Returns an ActiveKind + the SessionEnv (WAYLAND_DISPLAY/XDG_RUNTIME_DIR/DBUS/ XDG_CURRENT_DESKTOP) that targets it. - apply_session_env() writes that into the process env per connect (host serves one session at a time), so every backend (capture + input) opens against the live session; apply_input_env() points input at the matching backend and selects gamescope ATTACH (no managed restart) unless PUNKTFUNK_GAMESCOPE_MANAGED. - resolve_compositor() (native path) auto-detects + applies; explicit PUNKTFUNK_COMPOSITOR still wins (legacy/CI/forcing). detect() is now active-aware for the GameStream/mgmt callers too. - Bazzite host.env drops the static gamescope force; documents auto-detection + the optional overrides. Result: Desktop Mode → KWin/Mutter virtual output at the client's mode (churn-free, the reliable path); Gaming Mode → attach to the running gamescope (no SIGSEGV/GPU leak on reconnect). Compiles + clippy-clean; 78 host tests pass. Live validation on the Bazzite box pending (box offline). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-14 21:41:51 +00:00
enricobuehler	0bc60ebc44	fix(host/gamescope): free Steam from the autologin TV session while streaming ... On a Bazzite host that autologins into gaming mode on a physical display (the F44 default: gamescope-session-plus@ogui-steam on the TV), Steam — single-instance — is held by that session, which renders to the TV's native mode. The host-managed session then can't start its own Steam, so it captured the TV's 4K output instead of the client's mode (stretched). On F43 the box wasn't in gaming mode, so the host's Steam was the only one. Fix: on connect, the host-managed gamescope path stops any running autologin `gamescope-session-plus@*` unit (frees Steam) before launching its own session at the client's mode; on client disconnect (`restore_tv_session`, called from serve_session teardown) it stops our session and restarts the autologin one, so the TV returns to gaming mode by default when no one is streaming. Stopping the `--user` unit sticks (Relogin only fires on the full logind session ending — verified live), so no sddm config change is needed. Cost: a Steam cold-start per connect, given single-instance. No-op on non-Bazzite / headless boxes (nothing to stop → nothing to restore).

enricobuehler	b4a85a8610	feat(host/mgmt): mTLS auth — a paired client's cert authorizes the REST API ... Phase 1 of moving the library off a manual mgmt token: the management API now serves over HTTPS with the host's persistent identity (the cert clients already pin) and OPTIONAL client-cert auth. A request is authorized if EITHER the peer presented a client certificate whose SHA-256 is in the punktfunk/1 paired store (the same trust the QUIC data plane uses — so a paired native client needs no token), OR it carries the bearer token (the web console / admin). `/health` stays open. axum-server can't surface the peer cert to a handler, so `serve_https` runs the rustls handshake itself (tokio-rustls), reads the verified peer certificate, and serves the axum Router over hyper with the fingerprint attached to each request; `require_auth` checks it against `NativePairing::is_paired`. The verifier reuses the GameStream AcceptAnyClientCert, parameterized to make client auth optional (a browser with no cert still completes the handshake and falls back to the token). Validated live: paired cert → 200, unpaired cert / no creds / bad token → 401, bearer → 200, /health open. (Note: the API is now HTTPS with a self-signed cert — a browser shows a one-time trust prompt; native clients pin by fingerprint.) Next: Apple client presents its identity over mTLS (drops the token field); embed the web console; enable HTTPS mgmt by default.

enricobuehler	01409d9d8a	fix(host/dualsense): report full battery + log rumble forwarding ... Two DualSense (UHID) fixes surfaced live on the Bazzite host: - Battery: serialize_state never set the input report's status byte (struct off 52 → r[53]), so hid-playstation read battery capacity 0 and SteamOS warned "low battery" even on a fully-charged pad. Set it to 0x0A (discharging, low nibble 0xA → 100 %) — a virtual pad has no real cell. (Forwarding the client pad's real charge is a later feature.) Regression assert added to the layout test. - Rumble diagnostic: log the silent→active transition when forwarding a buzz on the 0xCA plane, so a live test can tell "host never receives rumble from the game" (Steam Input / parse) apart from "client doesn't render it". Once per buzz, no spam. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-14 16:14:28 +00:00
enricobuehler	27e58658af	feat(launch): punktfunk/1 launch integration — client picks a title, host runs it ... Plan step 4 (plumbing + host behavior). A client can ask the host to launch a library title on connect; the host resolves it against ITS OWN library and runs it in the session — the client sends only the store-qualified id, never a command, so a remote peer can't inject one. - Protocol (quic.rs): `Hello.launch: Option<String>` (the GameEntry id). Appended after `name`; when launch is present but name absent, a zero-length name placeholder keeps the offset deterministic — so a Hello with neither field stays byte-identical to the bitrate-era 26-byte form (test-asserted). Old peers ignore it; new hosts decode None from old clients. Round-trip + back-compat + truncation tests. - Host: `library::launch_command(id)` resolves id → command via the host's own library — `steam_appid` → `steam steam://rungameid/<appid>` (appid validated as digits, the only client-influenced part), `command` → the host-stored command verbatim (trusted, never from the client). m3.rs sets PUNKTFUNK_GAMESCOPE_APP from it before bringup, exactly as the GameStream /launch path does (one session at a time). Unit-tested incl. an injection-attempt guard. Takes effect on the bare-spawn gamescope path; a no-op on a shared desktop / attach-to-existing session. - C ABI: `punktfunk_connect_ex4` adds `launch_id` (NULL = none); `_ex3` now delegates to it. Threaded through NativeClient::connect → WorkerArgs → Hello. - client-rs gains `--launch ID` (headless testing); client-linux passes None (no picker yet). Header regenerated. Next: the Apple library grid passes the picked id via punktfunk_connect_ex4. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-14 14:56:18 +00:00
enricobuehler	6351d516e0	feat(host/library): game library API — Steam adapter + custom store ... A new `library` module + four mgmt endpoints surface the host's games to clients (plan: "surface the user's games"). An adapter layer (`LibraryProvider`) so future stores (Heroic/Epic, GOG, Lutris) slot in behind one uniform `GameEntry`. - SteamProvider: reads the LOCAL Steam install — no Steam Web API key, no network. Installed titles from steamapps/appmanifest_<appid>.acf; extra library folders (incl. paths with spaces) from libraryfolders.vdf; candidate roots cover classic, Flatpak and Deck layouts, canonicalized + deduped (the .steam/{steam,root} symlinks all fold to one). Runtimes/redistributables (Proton, Steam Linux Runtime, Steamworks Common, SteamVR) filtered out. Artwork = the public Steam CDN by appid (portrait/hero/logo/header), fetched directly by the client. - Custom store: ~/.config/punktfunk/library.json, write-then-rename persisted, CRUD'd via the API — the "create custom entries via the admin web UI" requirement. - API (under /api/v1, OpenAPI-documented + checked in): GET /library (all stores merged, sorted), POST /library/custom, PUT/DELETE /library/custom/{id}. - `punktfunk-host library` subcommand dumps the resolved library as JSON (diagnostic, mirrors `openapi`). Validated live against the real Steam library on the Bazzite box: 89 appmanifests → 78 games (11 tools filtered), correct titles/sort, and the CDN art URLs return 200. 5 unit tests for the VDF/ACF parsing, tool filter, art URLs, custom mapping.

enricobuehler	fc30307a87	feat(abi): expose the host-resolved compositor to clients ... Add punktfunk_connection_compositor() (mirrors punktfunk_connection_gamepad): a client getter for the compositor the host actually resolved for the session, read from Welcome.compositor and threaded through NativeClient.resolved_compositor. The Apple/Linux clients use it to enable the client-side cursor by default on gamescope sessions, whose PipeWire capture carries no cursor (verified upstream). Header regenerated.

enricobuehler	8425cd0826	fix(encode): probe each GPU's real max bitrate instead of failing (or blind-capping) ... Root cause of the Mac "session ended" at 880 Mbps / 1.3 Gbps: the host requests a bitrate NVENC can't express at any codec level and `avcodec_open2` returns EINVAL ("Invalid argument"), so the pipeline build fails after 4 identical retries and the session dies at encoder init — before a single video packet (which is why the client's UDP counters never moved). The ceiling is GPU/driver-specific: an RTX 4090 caps HEVC at ~800 Mbps (Level 6.2 High tier) and rejects above it, while an RTX 5070 Ti accepts 1.3 Gbps. Rather than hard-cap every build to a conservative guess (which would needlessly throttle capable cards), open_video now PROBES: open at the requested bitrate, and step down (codec spec ceiling, then 0.75x to a 50 Mbps floor) ONLY when this GPU returns EINVAL. Each GPU runs at its own real maximum — the 5070 Ti keeps 1.3 Gbps, the 4090 lands at 800 Mbps and streams instead of dying. Non-EINVAL failures (no GPU, bad mode, OOM) still surface immediately rather than being masked by retries. Codec::max_bitrate_bps is now just the first step-down candidate, not a clamp.

enricobuehler	4d26f61e40	fix(net/gso): fall back to sendmmsg on EMSGSIZE instead of tearing down ... Enabling PUNKTFUNK_GSO on a host whose egress MTU is below our UDP segment size made every GSO send return EMSGSIZE (code 90, "Message too long") — the kernel validates each GSO segment against the device MTU at send time, which plain sendmmsg does not. EMSGSIZE wasn't in gso_unsupported() (nor is_transient_io), so it propagated as a fatal "send failed — stopping stream" and instantly killed every session the moment GSO was on (observed live: connection fails instantly / speed-test 0 Mbps). Add EMSGSIZE to gso_unsupported() so it latches GSO off for the process and finishes via sendmmsg — the standard "GSO not usable on this path" fallback. Measured after: the same host+path does 1 Gbps at 0.0% loss over the real LAN via sendmmsg (and the host send path sustains a 2 Gbps probe with send_dropped=0), so GSO is a >2 Gbps optimization, not required for 1 Gbps.

enricobuehler	16ccc7c876	fix(net): don't tear the stream down on a connected-UDP ICMP blip (ECONNREFUSED) ... Root cause of the Mac "session ended" at higher bitrates. The video data plane is a *connected* UDP socket; with data-plane hole-punching the path can blip and the kernel surfaces an asynchronous ICMP port-unreachable/reset as ECONNREFUSED / ECONNRESET on a later send or recv. Both the host send loop and the client poll_frame treated that as fatal and tore the session down: ERROR punktfunk_host::m3: send failed — stopping stream error=send_sealed: Io(ConnectionRefused, code 111) <-- observed live That also cascades: a transient ICMP makes the client's poll_frame bail and close its data socket, which makes the host's next send get a *real* ECONNREFUSED, which tears the host side down too — exactly the "broke at 500 Mbps+" report. Fix: classify ECONNREFUSED/ECONNRESET alongside WouldBlock as transient (a lossy drop / "no data this poll"), never a teardown, at every data-path send/recv site (send, send_batch, send_gso, recv, recv_batch x2, recv_batch_x). FEC + the next frame/RFI recover; if the peer is genuinely gone the QUIC control plane's conn.closed() ends the session cleanly (no infinite "stream into the void"). This is the standard connected-UDP rule that ICMP errors are advisory — doubly true with hole-punching. Adds is_transient_io() + a unit test.

enricobuehler	c2ae40ef9e	feat(net/mac): default-on recvmsg_x batched Mac recv + GSO host + longer probe ... The Mac/iOS client's wall around ~380 Mbps on a 2.5 G path is the receive drain, not the transport: a loopback speed-test pushes 380/600/1000 Mbps at 0.0% loss, but Darwin has no recvmmsg(2), so the macOS client was doing one recv() syscall per packet — ~40-90k syscalls/s on one core. When the recv loop can't drain fast enough the kernel socket buffer backs up and drops, which the client sees as a sustained stream stalling/freezing in the 300-400 Mbps range (and an immediate "session ended" when a 500 Mbps+ first keyframe bursts in). - core/transport: flip recvmsg_x (the batched Darwin recv, ~30x fewer syscalls) from opt-in to default ON, opt-out via PUNKTFUNK_RECVMSG_X=0. Keeps the auto-fallback to the scalar loop on any unexpected syscall error. The Apple CI swift-test loopback now exercises this path by default. - packaging/kde host.env: enable PUNKTFUNK_GSO=1 — UDP segmentation offload on the host send path (one sendmsg per ~64 packets), the dominant lever above ~1 Gbps. Already wired (send_sealed -> send_gso) with sendmmsg auto-fallback. - apple SpeedTestSheet: lengthen the bandwidth probe 2 s -> 5 s so the measured number stops swinging wildly (50 vs 900 Mbps on the same link) — long enough for steady-state send + recv drain to settle. Matches host MAX_PROBE_MS. - host capture: PUNKTFUNK_SYNTH_NOISE synthetic high-entropy source for reproducible throughput testing of the encode->FEC->send->recv path.

enricobuehler	a3a3dfc85b	fix(vdisplay/kwin): make the streamed output the sole desktop (PUNKTFUNK_KWIN_VIRTUAL_PRIMARY) ... On a headless KDE appliance the session has two outputs — run-headless-kde.sh's `kwin --virtual` bootstrap (where plasmashell draws by default) and our per-session streamed output — so the client saw only the wallpaper of an empty extended output (the KWin analogue of the GNOME/Mutter VIRTUAL_PRIMARY issue). New opt-in PUNKTFUNK_KWIN_VIRTUAL_PRIMARY: after creating the virtual output, set it primary via kscreen-doctor (KWin then re-homes the desktop onto it and disables the bootstrap), then belt-and-suspenders disable anything still enabled. The keepalive re-enables the bootstrap on teardown — though KWin also auto-re-enables it when our output is reclaimed, so there's never a zero-output window. Set in packaging/kde/host.env. Verified live on the Fedora 44 KDE box: mid-session the streamed output is the sole desktop at 0,0; post-session the bootstrap is back.

enricobuehler	71f26083a6	bench(core): Tier-1 criterion microbenchmarks for the punktfunk/1 hot path ... GPU-free, so they run in normal CI. Two layers: crypto/{seal,seal_in_place,open} on one MTU shard, and pipeline/{gf8,gf16}/{64KB,1MB} — a whole frame through the real per-frame path end to end over the loopback transport (FEC encode → AES-GCM seal → packetize → reassemble → FEC decode → open). Baselines on the dev box (RTX 5070 Ti VM): AES-GCM ~1.57 GiB/s/shard; gf16 ~418 MiB/s at 1 MB vs gf8 ~23 MiB/s (the GF(2^8) O(n^2) ceiling the GF(2^16) Leopard wall-breaker removes — exactly the kind of regression this should catch). The GPU capture/NVENC path is out of scope here (Tier 3). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-13 19:18:40 +00:00
enricobuehler	7ec91aec2d	feat(punktfunk/1): cross-VLAN/NAT video via data-plane hole-punching ... The video data plane is a raw UDP socket separate from the QUIC control connection. On a flat LAN the host can send straight to the client, but across NAT or a stateful inter-VLAN firewall the unsolicited host→client video is rejected (ICMP port-unreachable → the session dies immediately, while control/audio/input keep working since they ride the client-initiated QUIC). Observed live: a client on 192.168.6.2 streaming from a host on 192.168.1.48. Fix: client-initiated hole-punching. The client sends PUNCH_MAGIC datagrams from its data socket to the host's advertised data port (Welcome.udp_port); that opens the firewall/NAT return path and lets the host learn the client's OBSERVED source (the NAT-translated address, not the client's reported private one). The host (UdpTransport::connect_via_punch) waits ≤2.5s for the first punch and streams there, falling back to the client-reported address for clients that don't punch (flat-LAN behaviour unchanged). The client keeps a low-rate keepalive so a stateful firewall's idle timeout can't close the path during a static, low-bitrate scene. Wired into client-rs and the NativeClient connector (covers the Linux + Apple clients; the Apple app needs an xcframework rebuild to pick up the new core).

enricobuehler	263eab31e3	fix(m3): release held mouse buttons/keys when a session ends (stuck-click after reconnect) ... The pointer/keyboard injector is host-lifetime (one EIS connection for every punktfunk/1 session), so its existing release_all only fires on EIS disconnect — never when a *client* session ends. A button still down at an abrupt client disconnect therefore stayed latched in the compositor: Mutter keeps the destroyed press's implicit pointer grab, so after reconnect a stuck left-button-down turns every motion into a drag (windows move, text selects) while a fresh click's press is swallowed — clicking buttons and text inputs does nothing. Only the one held button is affected; keyboard and the other buttons are fine, exactly as reported. Fix: input_thread now tracks the buttons/keys the client holds and, when the session ends, synthesizes the matching up-events through the host-lifetime injector (whose EIS connection — and the dangling grab — outlive the session). Backend-agnostic (normal inject path), so it covers libei/EIS, wlr and uinput alike. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-13 13:31:15 +00:00
enricobuehler	7ecf2d8dfd	fix(inject/libei): emit the continuous scroll axis so small scrolls register ... The libei backend forwarded mouse wheel only via scroll_discrete (120-per-detent). Mutter floors a sub-detent delta — a trackpad, a precise/high-res wheel, or a fractional smooth-scroll event — to zero whole clicks, so small scrolls never land and you have to spin the wheel a lot before anything moves. Emit the continuous `scroll` axis (logical px, ~15 px/detent) alongside the discrete steps, matching the wlroots backend's 15-px/notch behaviour, so every delta moves proportionally while full detents still drive line/page scrolling.

enricobuehler	55dfb4800f	fix(vdisplay/mutter): stop the teardown layout-restore from SIGSEGVing gnome-shell ... After a session ends, the Mutter backend (with PUNKTFUNK_MUTTER_VIRTUAL_PRIMARY=1) re-asserted the physical monitor layout with an explicit ApplyMonitorsConfig. On Mutter 50 + NVIDIA that monitor reconfig — issued while the just-removed high-refresh virtual output is still tearing down — SIGSEGVs gnome-shell. Observed live on home-worker-3: the teardown ApplyMonitorsConfig returns "recipient disconnected from message bus" (the shell died mid-call), GDM's crash-loop guard then drops to the greeter and STAYS there, so org.gnome.Mutter.RemoteDesktop/DisplayConfig vanish and every subsequent reconnect fails with RemoteDesktop.CreateSession ServiceUnknown — i.e. "after a disconnect I can't reconnect anymore." make_virtual_primary applies an APPLY_TEMPORARY config, which Mutter reverts on its own once the virtual output disappears and our DisplayConfig connection closes. So the explicit restore was both redundant and the crash trigger: drop it, drop the dc_pre connection at teardown, and let Mutter revert the temporary config itself. Setup is unchanged (the virtual output is still made primary so the desktop lands on the streamed surface). Removes the now-unused to_apply_logicals/apply_config helpers. Verified live on home-worker-3 (5120x1440@240, VIRTUAL_PRIMARY=1): 6/6 back-to-back connect/disconnect cycles streamed cleanly with gnome-shell holding the same PID throughout (previously it crashed within the first few disconnects).

enricobuehler	dad5a08c1f	chore(capture): tidy the GNOME flash diagnostic — it's the CORRUPTED skip ... Live confirmation on worker-3: the flash was Mutter's CORRUPTED, size-0 cursor-update buffers (chunk_flags=CORRUPTED) carrying recycled old frames — drained=1 always, so latest-frame-only draining wasn't the lever, the CORRUPTED skip was (OBS issue 8630). Demote the verbose drain diagnostic to a rate-limited debug line and document the root cause inline. Validated: zero-copy back on GNOME (dmabuf->CUDA, 5120x1440) AND flash-free with FORCE_SHM off.

enricobuehler	d8da12bbbd	fix(capture/mutter): latest-frame-only dequeue (the real GNOME flash fix) ... Deep research (OBS Studio's linux-pipewire, Mutter bug tracker) found the GNOME stale-frame flash is a buffer-RECYCLING race, not damage (Mutter sends whole frames, no SPA_META_VideoDamage) and not buffer count. OBS's proven fix is latest-frame-only dequeue: each process callback, drain ALL queued PipeWire buffers, requeue the older ones, and consume only the NEWEST — plus skip CORRUPTED buffers. Our code dequeued one buffer per callback (oldest-first) and the bounded channel dropped the NEWEST when full, so during Mutter's bursty delivery the encoder got stale frames → the flash. Switch the process callback to raw dequeue_raw_buffer + drain-to-newest (requeue older), extract the consume logic into consume_frame(spa_buf) sourcing datas via the transparent Data cast, skip SPA_META_HEADER_FLAG_CORRUPTED / CORRUPTED-chunk buffers (size-0 skip kept SHM-only so dmabuf isn't regressed), and remove the earlier content-hash drop heuristic (it couldn't tell stale re-deliveries from legit repeating content). Diagnostic logs drain depth + chunk/header flags. Reverts none of the FORCE_SHM / dmabuf_fence work. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-13 11:15:01 +00:00
enricobuehler	79508b2666	fix(capture/mutter): drop stale re-delivered frames (the GNOME flash) ... Instrumented worker-3: even on the ordered FORCE_SHM download path, Mutter re-delivers COMPLETE OLD pool buffers — 655 frames in a 15 s session whose content exactly matched an earlier frame (not damage-incremental; full old frames, in runs, ~45% during motion). NVIDIA gives no fence to prevent it, so the producer delivery can't be made clean from our side. Detect it and drop it: hash a spatial sample of each captured frame; a frame whose content equals an EARLIER distinct frame (vs the current one, whose duplicates pass through) is a stale re-delivery — skip it so the encoder never emits the flash (try_latest re-sends the last good frame; brief hold instead of a backward jump). Runs on the CPU/SHM path (where Mutter+NVIDIA capture lives); never triggers on static content or non-Mutter compositors (no reverts). PUNKTFUNK_KEEP_STALE=1 disables it for A/B.

enricobuehler	f9b857aac2	feat(capture): true SHM path (PUNKTFUNK_FORCE_SHM) for race-free Mutter+NVIDIA ... Empirically, Mutter+NVIDIA dmabuf capture has NO working GPU sync — confirmed on worker-3: explicit sync fails buffer alloc (EINVAL, no cogl sync_fd), and the dmabuf carries no implicit fence (EXPORT_SYNC_FILE waited=false). So any dmabuf read — zero-copy import OR mmap — races Mutter's render and flashes the buffer's previous frame. The prior "CPU fallback" still listed DmaBuf in its buffer types, so Mutter kept handing dmabufs and it never fixed anything (got worse). PUNKTFUNK_FORCE_SHM=1 offers MemPtr+MemFd ONLY (no DmaBuf), forcing Mutter to glReadPixels-download into mappable memory — which orders against its render, so the frame is complete + current by construction (race-free). Costs the download (~3 ms) + zero-copy; correct at 1080p/4K60. KWin/gamescope are unaffected (they blit into the buffer, no read-before-render race) and keep zero-copy.

enricobuehler	92c6da9546	fix(capture/mutter): restore zero-copy + sync via dmabuf implicit fence ... The previous attempt (8531135) dropped zero-copy on Mutter+NVIDIA for a sticky CPU/SHM fallback that (a) still listed SPA_DATA_DmaBuf in its buffer types, so Mutter kept handing dmabufs that got mmap-read UNsynced — making the flashing worse, not better — and (b) hinged on producer explicit sync, which Mutter+NVIDIA cannot do (`error alloc buffers` / no cogl sync_fd, confirmed in worker-3 logs). Revert the capture restructure to the original zero-copy dmabuf path, and fix the NVIDIA stale-frame race the RIGHT way for a producer that can't do explicit sync: the consumer snapshots the dmabuf's implicit fence (DMA_BUF_IOCTL_EXPORT_SYNC_FILE) and waits the producer's render before sampling (new dmabuf_fence module, ioctl number unit-tested). Covers the GPU import and the CPU mmap read. Logs once whether a render was actually in flight (waited=true → the driver fences and the race is closed; false → no implicit fence, so we learn zero-copy still needs SHM here). drm_sync (the explicit-sync primitive) is kept and verified but marked unused — no targeted compositor produces a usable sync_fd today; ready to wire in when one does. The Bug-2 input fix (held-key release on disconnect) from 8531135 is kept. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-13 09:28:17 +00:00
enricobuehler	8531135bb7	fix(capture/mutter): stale-frame flashes + stuck input after disconnect on GNOME ... Deep dive into the two GNOME-only host bugs (KWin/gamescope clean): 1. Stale-frame flashes (windows at old positions, typed text reverting): Mutter renders its virtual monitors DIRECTLY into the PipeWire buffer pool, and NVIDIA has no implicit dmabuf fencing — our zero-copy import raced the render and encoded each pool buffer's PREVIOUS contents. Fix, in order of preference: - Consumer-side PipeWire explicit sync (SPA_META_SyncTimeline): new drm_sync module (DRM timeline-syncobj wait/signal via raw ioctls, unit-tested incl. a live signal->wait round trip); announced post-format via update_params (the OBS pattern — at connect time the meta makes producers fail allocation, observed on KWin), with a blocks=3 Buffers filter so the producer's sync pod wins; acquire point awaited before any read (GPU import or CPU mmap), release point signaled on every path. - Where the producer can't do explicit sync (Mutter on NVIDIA today: no cogl sync_fd, "error alloc buffers"), a sticky fallback flips the capture to the synchronous CPU/shm path — Mutter's glReadPixels download orders against its render, so frames are correct by construction. First session pays one ~10 s probe+retry; later sessions go straight there. Validated live on home-worker-3 (GNOME 50 + RTX 4090): clean fallback, 30 MB HEVC streamed. - Sync is only announced on Mutter sessions (new VirtualOutput.mutter tag): KWin+NVIDIA fails allocation when merely asked, and doesn't need it (verified unchanged: zero-copy CUDA import + 1.1 MB/10 s). PUNKTFUNK_EXPLICIT_SYNC=0 disables the probe outright. 2. Clicks wedged in the focused app after disconnect+reconnect: a client vanishing mid-press left keys/buttons latched in the compositor — Mutter keeps the destroyed EIS device's implicit grab and the focused app stops taking clicks until restarted. EiState now tracks held keys/buttons/touches (wire codes) and synthesizes releases through the normal inject path before the EIS connection goes away. GNOME hosts on NVIDIA temporarily lose zero-copy (correctness over throughput); the moment Mutter+driver gain working explicit sync, the sync path engages automatically and zero-copy returns.

enricobuehler	2ebffe3457	perf(core): recvmsg_x batched receive on Apple (macOS client) ... macOS/iOS have no recvmmsg(2), so the Mac client did one recv() syscall per packet (non-allocating after the earlier fix, but still a syscall each — a single-core wall at line rate that Moonlight avoids). Add the Darwin recvmsg_x(2) batched-receive path (the recv counterpart of Linux recvmmsg): one syscall drains up to RECV_BATCH datagrams into the reused ring. struct msghdr_x + the extern aren't in the libc crate, so declared here (cfg target_vendor=apple). Opt-in via PUNKTFUNK_RECVMSG_X (it's FFI we can't exercise off-Apple) with auto-fallback to the tested scalar recv-loop on any unexpected error. Linux recvmmsg + the non-Apple scalar loop are unchanged; apple.yml compiles the path. Re GRO: Linux recv already batches via recvmmsg (32/syscall), so UDP GRO is only a marginal add there and needs a recv-path redesign to split coalesced buffers — deferred as low-ROI vs the Mac, which had no batching at all.

enricobuehler	9c86f667ca	perf(core): in-place AES-GCM seal + reused wire-buffer pool (host send) ... The host sealed every packet with ~3 heap allocations: aes-gcm's convenience encrypt() allocates the ciphertext Vec, seal_for_wire allocates the seq||ct||tag wire Vec, and seal_frame allocated a fresh Vec<Vec<u8>> per frame. At line rate (~250k–500k pkt/s for 2.5–5 Gbps) that's the single-core allocator wall. - SessionCrypto::seal_in_place uses AeadInPlace::encrypt_in_place_detached to encrypt into the caller's buffer and write the detached tag at the end — byte-identical to seal's ciphertext||tag, no allocation (unit-tested for byte equality + decrypt). - Session keeps a wire_pool the caller returns via reclaim_wires; seal_frame seals each packet in place into the reused buffers (clear() keeps capacity), so after warmup there's no per-packet ciphertext/wire allocation. paced_submit and submit_frame reclaim the pool after sending. End-to-end encrypted/lossless multi-frame tests stay green (validates the pool reuse doesn't corrupt across frames). Next: write packetize directly into a contiguous send buffer (kills the remaining shard allocs + GSO's coalescing copy).

enricobuehler	448986f41c	perf(core): UDP GSO send path (the multi-Gbps lever) ... sendmmsg already batches syscalls but still builds one sk_buff per datagram — the kernel-side wall above ~1 Gbps. UDP Generic Segmentation Offload hands the kernel one big buffer it splits into gso_size datagrams, building ~1 GSO skb per ≤64 segments. Research (LWN/Cloudflare/Tailscale) measures ~2.4x throughput at equal CPU and 17-44x fewer syscalls, and that sendmmsg batching alone is insufficient — you need true segmentation offload. Adds Transport::send_gso (default = send_batch) + a UdpTransport Linux override: coalesces a frame's equal-size wire packets (shards are zero-padded to a constant size, so a whole frame is one gso_size) into ≤64-segment sendmsg(UDP_SEGMENT) calls. seal/send routes through it. Opt-in via PUNKTFUNK_GSO (new unsafe hot-path code) with automatic fallback to sendmmsg on any GSO error (unsupported kernel/ path), latched per process. Loopback unit test validates the cmsg segmentation; full session over loopback streams clean (0% loss). Linux-only; loopback/non-Linux keep sendmmsg/scalar. Next levers: in-place AES-GCM seal (kill per-packet allocs), UDP GRO on recv, drop the sleep-pacing in favor of the kernel qdisc, jumbo MTU.

enricobuehler	4b1bbfdf0e	feat(client-linux): VAAPI hardware decode — zero-copy dmabuf into GraphicsOffload ... Stage 1.5: on Intel/AMD clients libavcodec's VAAPI hwaccel decodes on the GPU; frames map to DRM-PRIME dmabufs (av_hwframe_map, zero copy) and reach GTK as GdkDmabufTexture (BT.709 limited CICP color state — GDK's dmabuf default is BT.601). Inside GtkGraphicsOffload that is the decoder-to-subsurface path, direct-scanout eligible when fullscreen. Fallback ladder, live-verified on the NVIDIA dev box: no VAAPI device -> software decode at session start (logged reason); a mid-session VAAPI error (e.g. broken nvidia-vaapi-driver) demotes to software and the host's IDR/RFI recovery resynchronizes; a rejected dmabuf import logs and the stream continues. PUNKTFUNK_DECODER=software|vaapi overrides; the first-frame log now names the active path. The hwaccel path is raw ffmpeg-sys FFI (ffmpeg-next wraps none of it): hw device ctx + get_format pinned to AV_PIX_FMT_VAAPI (NONE on mismatch so cpu-fallback never silently engages inside libavcodec), thread_count=1, LOW_DELAY. Surface lifetime rides DrmFrameGuard into the texture's release func — GDK runs it on both success and failure. Needs an Intel/AMD client box (Steam Deck/Bazzite) to live-verify the hardware path; the software path is unchanged and revalidated.

enricobuehler	b5c30dff4f	perf(host): lift bitrate cap to 8G, raise MTU to 1452, FEC env knob ... Groundwork for multi-Gbps (2.5G link here, 5G to the Mac Studio). The encoder is pixel-rate bound, not bitrate bound, so these unblock the transport: - MAX_BITRATE_KBPS 2G -> 8G, MAX_PROBE_KBPS 3G -> 10G (the cap was policy, not a hardware limit — NVENC emits multi-Gbps trivially with the 2-way split). - Welcome shard_payload 1200 -> 1452: fills a 1500 MTU, ~17% fewer packets for free (even size, FEC-safe; negotiated so the client follows). - PUNKTFUNK_FEC_PCT env overrides the 20% FEC default — a clean wired LAN can drop it (every recovery shard is wire bytes+packets); 0 disables FEC. Next: UDP GSO (the dominant lever — research shows ~2.4x throughput / ~40x fewer syscalls; sendmmsg batching alone is insufficient) + in-place AES-GCM seal.

enricobuehler	11fc3be726	fix(core): libc is a unix-wide dep — unbreak iOS/tvOS xcframework slices ... 6b5ee9f added a libc-based batched recv_batch for the Apple/BSD targets (cfg(all(unix, not(target_os = "linux")))) but left libc declared only under cfg(target_os = "linux"). The macOS host build pulls libc in transitively so it compiled, but the iOS/tvOS cross-compiles (no transitive libc, dev-deps off) failed with E0433 "cannot find crate libc", breaking the full xcframework build. Widen the gate to cfg(unix): libc is now used by sendmmsg/recvmmsg on Linux AND recv() on the other unix (Apple/BSD) targets. Verified: cargo build --release -p punktfunk-core --features quic for aarch64-apple-ios, x86_64-apple-ios, and aarch64-apple-tvos (-Z build-std) all link.

enricobuehler	6b5ee9f47b	perf(core): batched non-allocating recv on Apple targets (macOS client wall) ... The batched `recvmmsg` recv path was Linux-only; macOS fell back to the trait default, which calls the scalar `recv` — a fresh `vec![0u8; 2049]` allocation (plus zeroing and a copy) PER PACKET on the single receive thread. At line rate that alloc/free churn, not the syscall, was the single-core wall: measured the real Mac client topping out ~315 Mbps and dropping the session at 800, while a Linux client (recvmmsg) held a clean 1 Gbps against the same host, and Moonlight (batched recv) does 900 on the same Mac. Add a `cfg(all(unix, not(linux)))` `recv_batch` that drains up to RECV_BATCH datagrams per call with `libc::recv(MSG_DONTWAIT)` straight into the caller's reused ring buffers — no per-packet allocation or copy. Still one syscall per datagram (a future `recvmsg_x` batch would cut that too), but it removes the dominant cost. Linux recvmmsg path and the Windows/loopback default unchanged.

enricobuehler	c56b1b455a	feat(punktfunk/1): request-IDR recovery for a wedged client decode ... Fixes the intermittent first-connect freeze. The host streams infinite GOP — one opening IDR, then P-frames only (recovery keyframes just on loss) — so when the client's decoder wedges on the cold first session (a lost/corrupt opening IDR, a bad early P-frame) the picture stays frozen until the far-off next keyframe. The client had no way to ask for one; now it does. Add a RequestKeyframe control message (client -> host, reliable control stream), mirroring Reconfigure: - core: quic.rs RequestKeyframe (type 0x03) + roundtrip test; client.rs CtrlRequest::Keyframe + NativeClient::request_keyframe; abi.rs punktfunk_connection_request_keyframe (header regenerated). - host: m3.rs decodes it in the control loop and signals the encode loop, which coalesces a burst and calls enc.request_keyframe() — wiring the existing NvencEncoder hook (force_kf -> next frame pict_type=I), the same recovery the GameStream path already had via force_idr. - apple: PunktfunkConnection.requestKeyframe(); StreamPump (stage-1) requests on layer.status==.failed; Stage2Pipeline (stage-2) on a sync submit failure and on the async decode-error callback via a thread-safe KeyframeRecovery. All throttled to <=1/250ms (the decode stays wedged for several frames until the IDR lands, so per-frame requests would flood the control stream). Self-healing: a lost recovery IDR is re-requested after the throttle; the host coalesces bursts into a single IDR. Validated: cargo fmt + clippy clean; core + host test suites green (incl. new request_keyframe_roundtrip); swift build + test (39 passed); xcframework rebuilt (all 5 slices), header regenerated with no unrelated drift.

enricobuehler	a95984bb4f	feat(client-linux): feature parity with the Swift client ... Everything the macOS app does that stage 1 lacked, before any new feature work (user directive): - Input capture is now a deliberate, reversible STATE (Moonlight- style): engaged on stream start and click-into-video (the engaging click is suppressed), released by Ctrl+Alt+Shift+Q (toggles) or focus loss; held keys/buttons are flushed host-side on release; cursor hiding + shortcut inhibition follow the state; HUD hint when released. Per-session window handlers disconnect with the page. - Gamepads: app-lifetime SDL service (GamepadManager parity) — pad list + "Forwarded controller" pin in Settings (auto = most recent), "Automatic" pad TYPE resolves from the physical pad at connect; DualSense touchpad contacts + ~250 Hz motion samples on the 0xCC plane (Swift GamepadWire scale constants); feedback grows adaptive- trigger replay and player LEDs via raw DS5 effects packets (the wire's 11-byte blocks drop into SDL_SendGamepadEffect verbatim); held pad state zeroed on pad switch/detach. sdl3 "hidapi" feature. - Microphone uplink: PipeWire capture -> Opus 20 ms -> 0xCB datagrams (validated live: host received 711 mic packets), Settings toggle. - Speed test per saved host (Swift's "Test Network Speed…"): 2 s probe burst, goodput/loss + recommended ~70 % bitrate, one-tap apply. - Settings: host compositor preference (sent in the Hello), native- display resolution/refresh resolved from the window's monitor at connect (new default), bitrate ceiling to 3 Gbit/s. - Hosts page: saved/trusted hosts section for direct pinned reconnect (mDNS not required), rebuilt on every page return. Deliberately not ported: audio device pickers (PipeWire routing owns this on Linux), resize-to-request_mode (not wired in Swift either), pointer-lock relative mouse (stage-2 presenter, needs raw Wayland). DualSense fidelity needs a physical pad to live-verify. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-06-12 21:11:52 +00:00
enricobuehler	dea749186d	fix(quic/apple): QUIC keep-alive + reconnect input re-engage ... Three native-client bugs isolated against a stock Moonlight client (which stays connected / keeps input working under the same actions): - Connection drops mid-stream: the quinn endpoints (host + client) ran with default transport config, so keep_alive_interval was OFF. Any quiet stretch (no input, audio muted/stalled, a capture hiccup, a mode change) let the idle timer expire and quinn closed the session -> next_au=Closed -> "Session ended". Moonlight's ENet sends keepalive pings; we sent nothing. Add a shared TransportConfig (keep-alive 4s under an explicit 20s idle timeout) to both endpoint::server_from_der and endpoint::client_pinned_with_identity. - Reconnect input dead (macOS): the session-start auto-capture one-shot was consumed even when engageCapture(fromClick:false) was refused (window not key yet at the instant of reconnect), with no retry -> capture stayed off and input never forwarded. Clear the one-shot only on a successful engage, and retry on NSWindow.didBecomeKey. Stays scoped to session start, so it does not resurrect the rejected auto-grab-on-activation behavior. - Reconnect input dead (iOS): wasCapturedOnResign leaked stale state across sessions and the foreground-restore could fire before this session's InputCapture was wired (setForwarding no-ops on nil). Reset it per session in start() and guard the didBecomeActive restore on inputCapture != nil. Validated: cargo build -p punktfunk-core --features quic; swift build; swift test (39 passed, 0 failures); xcframework rebuilt (all 5 slices), no ABI/header drift.

enricobuehler	a8a6224fd8	fix(encode): bound per-frame size with a tight VBV buffer ... NVENC ran CBR (bit_rate == max_bit_rate, rc=cbr) but never set rc_buffer_size, so it used a loose default VBV. A high-motion P-frame was then allowed to spike to many times the average frame size; the extra packets overflow the depth-2 send queue (newest frame dropped) and the kernel UDP buffer (WouldBlock drops), which the client sees as framedrops/jitter — and on the infinite-GOP GameStream path as old/stale frames flashing until the next RFI. Set a tight ~1-frame VBV (rc_buffer_size = bitrate/fps) so the encoder holds frame size roughly constant and absorbs motion as a momentary QP/quality dip instead — the Sunshine/Moonlight low-latency model. Tunable via PUNKTFUNK_VBV_FRAMES (default 1.0); larger trades burst tolerance for motion quality. Fixes both the punktfunk/1 and GameStream paths (shared encoder).

enricobuehler	5f088c6f56	fix(client-linux): absolute mouse was dropped — pack the surface size in flags ... The MouseMoveAbs wire contract packs the client coordinate-space size as (width << 16) | height in `flags` (same as touch); injectors normalize against it and drop the event when it is zero. The GTK client sent flags=0, so KWin's libei path refused every motion (`emitted=false`) — found via the first real user test from home-worker-3. - ui_stream: send_abs() packs the negotiated mode into flags for motion + click-position events. - core input.rs: document the contract on MouseMoveAbs itself (it was only implied by TouchDown's doc). - client-rs --input-test: add a MouseMoveAbs sweep so the absolute path stays covered — Moonlight and the Mac client only send relative motion, which is why this gap survived every prior live test.

enricobuehler	96a35ca84c	feat(client-linux): native GTK4 client — stage 1, first light at 1080p60 ... New crate crates/punktfunk-client-linux (binary punktfunk-client), the native Linux client on the Option A architecture (2026-06-12 research): - GTK4/libadwaita shell linking punktfunk-core directly (no C ABI): mDNS host list, TOFU fingerprint prompt, SPAKE2 PIN pairing dialog, preferences (mode/bitrate/gamepad/shortcut capture), stats overlay, --connect host[:port] for scripting. - Video: FFmpeg software HEVC decode (LOW_DELAY, slice threads) -> RGBA -> GdkMemoryTexture inside GtkGraphicsOffload (the dmabuf subsurface path lights up when VAAPI lands; black-background keeps fullscreen scanout-eligible). - Audio: Opus -> PipeWire playback stream, the host virtual-mic's adaptive jitter ring inverted. - Input: keyboard as the exact inverse of the host VK table (evdev keycodes, layout-independent; unit-tested), absolute mouse through the Contain-fit transform, WHEEL_DELTA(120) scroll, compositor shortcut inhibition while streaming, Ctrl+Alt+Shift+Q release chord, F11 fullscreen. SDL3 gamepad capture (single pad-0 model) + rumble and DualSense lightbar feedback on the same thread. - Session pump owns video+audio pulls; the gamepad thread owns rumble+hidout — possible because NativeClient's plane receivers are now mutexed, making it Sync (Arc-shared, compiler-verified per-plane contract instead of the ABI's manual assertion). - Linux-gated deps + a stub main keep cargo build --workspace green on macOS. Validated live against serve --native on this box: 1920x1080@60, locked 60 fps, capture->decoded p50 ~6.4 ms (software decode, debug build). Teardown keys off AdwNavigationPage::hidden — NavigationView push fires a transient unmap/map cycle that must not end the session.

enricobuehler	99b4de32ee	feat(pairing): delegated approval (§8b-1) — approve an unpaired device from the console ... An identified-but-unpaired device that knocks on a pairing-required host is now held as a pending request the operator approves from the web console — pairing it with no PIN fetched out of band — instead of a flat reject. - core: Hello gains an optional trailing device name (len u8 || UTF-8, ≤64, same trailing-back-compat pattern as compositor/gamepad/bitrate). client-rs --name sends it; the connector sends None (fingerprint-derived label). - native_pairing: in-memory pending queue (note_pending dedups by fingerprint, evicts the least-recently-active past a 32 cap, 10-min TTL); approve_pending pins the fingerprint, deny drops it. Names are sanitized (strip control/ANSI/ bidi — untrusted wire input); add()/remove() roll back in-memory on a persist failure; pairing clears any stale pending knock. - m3: the require_pairing gate records the knock (sanitized label) before rejecting; anonymous (certless) clients record nothing. - mgmt: GET /native/pending, POST /native/pending/{id}/approve (optional {name}) and /deny; OpenAPI + tests; docs/api/openapi.json regenerated. - web: a "Waiting for approval" section on the Pairing page (live-poll, Approve/ Deny, error-surfaced via QueryState); en+de strings. - Also completes an in-progress NativeClient Sync refactor (receivers behind per-plane mutexes) that was left half-applied in the tree. Adversarially reviewed (4 lenses + 3-vote verify); the confirmed findings are fixed here. Validated live on the GNOME box: knock (with a wire name, and a malicious ANSI/bidi name that got neutralized) → pending → approve → the same identity streams real video. Full workspace tests + clippy + fmt green; web tsc clean. Roadmap §8b-1 marked done; §8b-2 (peer-push approval) is the client follow-up. See docs-site pairing page.

enricobuehler	c8099c0125	fix(vdisplay/mutter): stop screencast before monitor reconfig — fixes >60Hz teardown crash ... The high-refresh teardown SIGSEGV was caused by ApplyMonitorsConfig disabling the still-actively-captured high-refresh virtual output. Reorder teardown: Stop the screencast FIRST (Mutter removes the virtual + auto-reverts the temporary config), then re-assert the physical layout once the virtual is gone. Never reconfigure a live virtual CRTC. With this, PUNKTFUNK_MUTTER_VIRTUAL_REFRESH=1 is stable: validated at 5120x1440@240 on Mutter 50 + NVIDIA — virtual output Meta-0@240, real 240fps, gnome-shell survives back-to-back sessions + teardowns, physical (HDMI-1) restored each time.

Pinning the virtual output to a high client refresh via RecordVirtual "modes" works mid-stream, but a high-refresh virtual CRTC SIGSEGVs gnome-shell on session TEARDOWN (observed at 5120x1440@240) — taking down the whole GNOME session, so subsequent connects fail with RemoteDesktop ServiceUnknown. Gate it behind PUNKTFUNK_MUTTER_VIRTUAL_REFRESH, default OFF — Mutter then derives the virtual monitor's refresh from the PipeWire framerate (60Hz, stable). The >60Hz path stays in-tree for investigation; re-enable once the teardown crash is understood. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-12 13:59:29 +00:00
enricobuehler	f6a7f3c12d	feat(vdisplay/mutter): pin the virtual output to the client's refresh (>60 Hz) ... RecordVirtual without a "modes" property makes Mutter derive the virtual monitor's refresh from the PipeWire stream framerate and default to 60 Hz — so a 240 Hz client mode rendered at 60 (the encoder just padded to 240 with duplicate frames). Pass an explicit "modes" entry (size + refresh-rate + is-preferred) so Mutter creates the virtual monitor at the client's exact WxH@Hz. Mutter >= 47; older Mutter ignores the unknown key (60 Hz fallback, no regression). Confirmed first via raw D-Bus on the box, then validated end-to-end: the virtual output Meta-0 reports 1920x1080@240.00 and the host encodes 480 *immediate* (real, not paced) frames per 2 s.

Keeping the physical monitor enabled as a secondary let the cursor, windows, and keyboard focus land on it — relative pointer motion wandered off the streamed surface, so on the client the cursor "disappeared" and clicks/keys went nowhere visible. Omit the physical outputs from ApplyMonitorsConfig so Mutter disables them for the session; everything is confined to the streamed virtual output. Restored on teardown. Validated on-box: mid-session DisplayConfig shows only the virtual output (Meta-0) as the sole primary; the physical (HDMI-1) is restored after the session ends.

Add EiSource::MutterEis: obtain the EIS fd from org.gnome.Mutter.RemoteDesktop.Session.ConnectToEIS (CreateSession → Start → ConnectToEIS), no portal and no approval.

enricobuehler	94552331ef	feat(host): concurrent punktfunk/1 sessions (bounded by --max-concurrent) ... The accept loop no longer awaits each session inline — it spawns each onto a JoinSet, bounded by a semaphore (--max-concurrent, default 4: a NVENC session bound; overflow clients wait in QUIC's accept backlog until a slot frees). The QUIC handshake stays in the accept loop so a failed handshake (e.g. a pin mismatch where the client aborts) doesn't consume a session slot or block accepting the next client; the slow part (control handshake, pairing, the capture/encode pipeline) runs in the spawned task. Each session already had its own virtual output + NVENC encoder; the host-lifetime input/audio/mic services stay shared — the natural "multiple devices viewing/controlling the same desktop" semantic on kwin/mutter/wlroots. gamescope's independent-desktops (per-session input/audio) isolation is a follow-up. New M3Options.max_concurrent + the `--max-concurrent` CLI flag. Validated live (GNOME box): two clients connected at once -> two independent Mutter virtual outputs (720p60 + 1080p60) streaming simultaneously (39 MB + 48 MB). All 61 host tests green (the c_abi/pairing tests exercise the new loop + the failed-handshake-doesn't-count semantics).
