enricobuehler	b53710da1a	feat(vdisplay): harden keep-alive reconnect — same-client preempt, quit-skips-linger, configurable idle ... On-glass testing (Test 2, KWin .116) surfaced that a reconnect within the QUIC idle-timeout window (~8s) lands on a fresh SECOND display instead of reusing the kept one: the old session was still Active (not yet Lingering), so the registry's keep-alive reuse (which only matches Lingering) skipped it and the old session kept streaming to nobody. Three fixes: #3 Same-client reconnect preempt (the real fix): admission::preempt_same_identity() lists a reconnecting client's OWN still-live session(s) (same cert fingerprint); serve_session signals their stop + waits the release grace BEFORE acquiring, so the zombie tears down → its display lingers → the reconnect REUSES it instead of making a second. Implements the "preempts downstream" the admission docs already promised. Independent of the mode_conflict policy; the pure core (same_identity_stops) is unit-tested. #2 Deliberate quit skips linger: a client that deliberately disconnects closes the QUIC connection with QUIT_CLOSE_CODE (0x51, shared in core::quic); the host reads the ApplicationClosed reason and tears the display down immediately (registry release() gained force_immediate → Linger::Immediate; multi-session-safe via the pure lifecycle machine), while a bare disconnect still lingers for reconnect. Threaded via a session quit flag → the DisplayLease. NativeClient::disconnect_quit() + punktfunk-probe --quit drive it; GameStream (Quit App / h_cancel) is a documented follow-up. #1 Configurable disconnect-detection latency: the QUIC control-connection idle timeout (stream_transport, 8s default) is host-tunable via --idle-timeout-ms / PUNKTFUNK_IDLE_TIMEOUT_MS, clamped >=1s with a keep-alive that scales to it so a live session never false-closes. Default unchanged (8s stays load-bearing for the Windows IDD-push reconnect flow). Workspace check + 63 core / 215 host / 47 vdisplay tests green; clippy clean.

enricobuehler	62e0367f4b	feat(punktfunk1): configurable data-plane UDP port (--data-port) ... The native data plane used a random ephemeral UDP port (hole-punched), which a strict firewall can't pre-open — so remote clients behind one couldn't connect. Add an optional fixed data port: - `Punktfunk1Options`/`NativeServe` gain `data_port`; `bind_data_socket` binds the fixed port (→ direct, no hole-punch) or falls back to a random port + hole-punch when unset or the fixed port is busy (a concurrent session already holds it). - `UdpTransport::from_socket`/`from_socket_punch` adopt an already-bound socket, so the host keeps the SAME data socket from handshake through streaming — no drop-then-rebind window in which a concurrent session could steal a fixed port. - `main.rs` wires the CLI flag through to `NativeServe`. - Firewall docs updated (troubleshooting.md + apt/pacman/bazzite READMEs): control plane is the fixed UDP 9777; the data plane is a separate random port that usually needs no rule, with the fixed-port option for strict firewalls. Unit-tested: default random+hole-punch, and fixed-port-then-fallback-when-busy. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-05 13:53:54 +00:00
enricobuehler	677a4f4cf5	perf(gamestream): move FEC packetization off the encode loop (3-stage pipeline) ... FEC/Reed-Solomon packetization ran inline on the encode loop (~3 ms/frame at 4K), serializing behind encode and capping the GameStream frame rate below what the encoder alone can sustain. Split it into a 3-stage pipeline, each stage on its own thread joined by a depth-2 bounded queue: encode loop → [raw AUs] → packetizer (FEC/RS) → [wire batch] → paced sender - `spawn_packetizer`: turns each `RawFrame`'s access units into wire datagrams via the stateful VideoPacketizer, off the encode loop. Above-normal priority (on the per-frame critical path). Tallies goodput (bytes to the wire) for the stats window. - Backpressure chains up: a slow sender blocks the packetizer, which fills the encode→packetizer queue, which makes the encode loop drop the NEWEST frame — encode itself never waits. - A dropped frame now consumes no client-visible frameIndex (packetization is downstream), so the host re-anchors the reference chain: a drop arms a keyframe on the next iteration (`recover_after_drop`), routed through the same coalesce gate as client IDR requests so a burst of drops (congestion) can't become an IDR storm. - Perf/stats relabeled: `pkt` = AU drain, `send` = enqueue to the pipeline (both should be near-zero now; nonzero = encode being stalled by pipeline backpressure). Goodput read from the packetizer's atomic at the 1 s stats boundary. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-05 13:53:43 +00:00
enricobuehler	87435e6547	feat(vdisplay): complete Stage 5 §6A group semantics — per-group restore, Mutter group-aware, gamescope groups ... Host-side completion of Stage 5 (§6A many-clients-as-monitors), all unit-tested; two-session on-glass validation still pending (no GPU on the dev VM): - Per-group topology restore (§6.1): the KWin `exclusive` restore no longer rides the per-session StopGuard (which re-enabled the physical the moment the FIRST of several exclusive sessions dropped, under a live sibling). KWin hands its restore to the registry as a closure (new trait `take_topology_restore`); the registry keeps it in the display group (`Entry.topology_restore`) and, on teardown, floats it to a surviving same-group sibling (`hand_off_restore`) or runs it when the group empties — outside the lock, before the last output's keepalive drops, so the compositor never sees zero outputs. All three teardown paths (lease drop / linger expiry / mgmt release) honor it. Single-display path byte-for-byte unchanged. Unit-tested: float / run-on-last / non-carrier-first / never-cross-backend. - Mutter group-aware (new trait `set_first_in_group`): the registry tells each backend whether it's the first display of its group; a non-first Mutter session EXTENDS into the already-exclusive desktop instead of re-applying a sole-monitor ApplyMonitorsConfig that would disable the first session's virtual. (Mutter connectors are un-nameable, so it can't build a keep-all-virtuals config; skipping is the safe equivalent.) Single-session unchanged. Residual APPLY_TEMPORARY revert documented. - gamescope groups (§6.1): `registry::group_key` makes each gamescope spawn its own group (independent nested session, no shared desktop) — never auto-rowed against or restore-/topology-grouped with another gamescope. Applied in both the /display/state assembly and the acquire-time position computation. Unit-tested. Remaining Stage 5: the web console arrangement table, on-glass validation, and the documented residuals (wlroots exclusive, Mutter APPLY_TEMPORARY). design doc updated. cargo build/test (214)/clippy --all-targets/fmt green.

enricobuehler	e0f15822ae	feat(vdisplay): Stage 5 layout foundation — arrangement engine + /display/layout + group placement ... §6A layout, riding the Stages 1-3 registry with no protocol change: - vdisplay/layout.rs: pure arrangement engine — auto-row (left-to-right in acquire order, top-aligned) + manual (per-identity-slot offsets, auto-row fallback for unpinned members). Unit-tested. - Registry group model (Linux): group = backend (one desktop per compositor session). /display/state groups entries, orders by acquire (gen), and computes each member's position via the engine (pure `assemble_displays`, unit-tested). DisplayInfo carries group/display_index/position/identity_slot/topology. The backend reports its resolved slot via the new VirtualDisplay::last_identity_slot (KWin only), so the arrangement + state key on per-client identity. - Registry-driven position apply: new VirtualDisplay::apply_position(x,y) (default no-op; KWin drives kscreen-doctor). Right after create the registry computes the new display's position over its whole group (pure `position_for_new`, unit-tested) and applies it — one seam for BOTH deterministic auto-row AND manual placement. Guarded: the origin (0,0) is skipped, so a single-display / first-of-group session (and every non-KWin backend) issues no positioning — the historical single-display path is unchanged. On-glass-validation-pending. - PUT /api/v1/display/layout: persists the console's manual arrangement via the pure EffectivePolicy::with_manual_layout transform (locks current effective behavior into explicit Custom fields + sets a manual layout, so arranging is orthogonal to the other axes). OpenAPI regenerated. - /display/settings `enforced` now lists all five axes (keep_alive, topology, mode_conflict [Stage 4], identity [Stage 3], layout [Stage 5]) — was stale at keep_alive+topology; the console reads it to know which controls are live. Still Stage-5 TODO (design/display-management.md §11): Mutter/wlroots group-aware analogues, per-group topology restore, the web arrangement table, gamescope decline. cargo build/test/clippy/fmt green; OpenAPI in sync.

enricobuehler	eddcd91f48	feat(vdisplay/kwin): group-aware exclusive — never disable a sibling output (Stage 5 §6.1) ... The critical latent bug Stage 3 introduced: per-slot output names mean a 2nd exclusive session's other_enabled_outputs() (which disabled 'everything not named Virtual-punktfunk') would black out the 1st session's Virtual-punktfunk-<id> output. Fix: recognise the whole managed group by the shared Virtual-punktfunk prefix — exclusive now disables only NON-managed outputs (bootstrap/physical), never a group sibling. Plus first-slot-wins for the group primary (a_managed_output_is_primary): a later session joins as a secondary monitor of the shared desktop instead of stealing the shell off the first. Unit-tested. Start of Stage 5 (§6A many-clients-one-desktop). Remaining: Mutter/wlroots group-aware analogues, layout (auto-row/manual + /display/layout + console), per-group topology restore, gamescope groups.

enricobuehler	23446fa177	fix(vdisplay): Windows admission default is reject, not join (single-capturer limit) ... Two concurrent Windows sessions both drive the same pf-vdisplay monitor's single-capturer IDD-push channel (newest-delivery-wins), which freezes the live client and can wedge the driver (observed live: a concurrent-session test wedged .173 → Moonlight 'no video'; needed a reboot). True multi-session capture is §6.6/ Stage 7. So on Windows 'separate' (incl. the unconfigured default) now resolves to REJECT — a 2nd client gets a clean 503 and the live session is protected — instead of join (which would freeze it). join/steal stay explicit opt-ins; Linux keeps separate (real multi-view). Centralized as admission::effective_conflict(), shared by the native handshake + GameStream h_launch. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-05 11:32:52 +00:00
enricobuehler	980939ed6b	refactor(gamestream): extract + unit-test gamestream_admission (Stage 4) ... Pull the GameStream mode-conflict decision out of h_launch into a pure gamestream_admission(live, req_fp, policy) -> GsDecision so the 503/join/take-over logic is unit-tested (no live session / same-client → Serve; different client → Reject/Join/Serve per policy; anonymous requester treated as different) — the GameStream path can't be driven without a Moonlight client, so this covers the logic.

enricobuehler	cfad0cf7ee	feat(vdisplay): finish Stage 4 — typed reject, Windows join-default, GameStream 503 ... Completes the mode-conflict admission surface deferred from the initial Stage 4: - REJECT now delivers the reason to the client: punktfunk/1 closes the QUIC connection with a distinct BUSY code (0x42) + the 'host busy: streaming WxH@Hz to <client>' string, which the client reads from ApplicationClosed (validated on loopback: the probe logs 'closed by peer: host busy … (code 66)'). - Windows default: separate (incl. the unconfigured default) resolves to JOIN — the Windows native host admits a second client at the live mode instead of the old silent last-wins reconfigure of the shared monitor (release-note behavior fix; the reconfigure is now opt-in as steal). separate stays multi-view on Linux. - GameStream 503: h_launch tracks the session owner fp (LaunchSession.owner_fp, kept [u8;32] for Copy) and applies the policy when a DIFFERENT paired client launches — reject → 503 (Moonlight 'host busy'), join → serve the live mode, steal/separate → take over. Same-client re-launch is never a conflict. Native reject-reason loopback-validated; Windows join-default pending .173 rebuild; GameStream 503 pending a Moonlight client (can't drive /launch autonomously).

enricobuehler	42b1158ea7	feat(vdisplay): mode-conflict admission — separate/join/steal/reject (Stage 4) ... The mode_conflict policy is now enforced at ADMISSION, before the punktfunk/1 Welcome, when a DIFFERENT client connects while another client's session is live: - separate (default, unconfigured → no change): each client its own display. - join: admit at the live display's mode (honest-downgrade — the Welcome carries it). - steal: signal the victim session(s)' stop flags, wait the release grace, serve. - reject: refuse the handshake with a busy reason (live mode + client label). New vdisplay/admission.rs: the pure decide() (unit-tested — same-client never conflicts, anonymous clients each distinct, join targets the oldest session) + a live-session registry (identity + mode + stop flag) sessions register in once up. Wired into punktfunk1 serve_session: admit() before validate_dimensions, register after the data plane binds. A same-client reconnect never conflicts. Validated on loopback (two probes, distinct identities, differing modes) across all four policies: separate→own mode, join→live mode, steal→victim interrupted, reject→handshake refused. Remaining Stage-4 surface (deferred): GameStream 503 path, Windows-specific defaults (separate→join map, silent-reconfigure→steal), reject reason delivered to the client as a typed message (currently host-side log + connection close).

enricobuehler	029d1134a9	harden(vdisplay/windows): verify+retry exclusive isolation; pack primary layout ... Exclusive (topology=exclusive) was fire-and-forget — a field-reported bug had a physical monitor STAY ACTIVE. isolate_displays_ccd now re-queries after each apply and RETRIES (up to 4x) until count_other_active()==0, never trusting rc alone; logs SOLE-active on success, an error if a display survives all attempts. Secure desktop correctness depends on the lock screen not landing on a stray panel. Primary: drop the temporary per-path diagnostic; pack the kept displays left-to- right from the virtual's right edge instead of blindly shifting each by virt_width (which left a dead gap when extend already placed them right).

enricobuehler	e35b6991e2	fix(vdisplay/windows): topology=primary force-extends to reactivate the physical ... Root cause: on a headless box the IDD auto-activates as the SOLE display, so QueryDisplayConfig sees only the virtual — the physical is already deactivated before set_virtual_primary_ccd runs (no physical to keep). Force EXTEND first to reactivate every connected display alongside the virtual, then reposition to make the virtual primary, keeping the physical active.

enricobuehler	913f6ce659	diag(vdisplay/windows): log active paths in set_virtual_primary_ccd ...

enricobuehler	d23bd9b0cf	fix(vdisplay/windows): DISPLAYCONFIG_PATH_SOURCE_INFO union field access ... modeInfoIdx lives in the Anonymous union (windows-rs), not directly on sourceInfo — set_virtual_primary_ccd now reads .Anonymous.modeInfoIdx.

enricobuehler	eda7cac78e	feat(vdisplay/windows): topology=primary — keep physicals active, virtual primary ... Implements the deferred Windows primary-only CCD (Stage 2). set_virtual_primary_ccd repositions the virtual output's source to (0,0) = primary and shifts the physical display(s) to its right, ALL kept active — one atomic CCD SetDisplayConfig (not GDI CDS_SET_PRIMARY, which storms MODE_CHANGE_IN_PROGRESS with another display live). The manager's should_isolate() becomes topology_action() (3-way): extend (skip), primary (set_virtual_primary_ccd), exclusive (isolate_displays_ccd). Restore-on-teardown covers both. Validates the user's two scenarios on a physical-monitor .173. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-05 09:17:41 +00:00
enricobuehler	d73951414c	feat(vdisplay): KWin per-slot output naming for persistent scaling (Stage 3) ... The KWin backend names its output Virtual-punktfunk-<id> from the client's stable identity slot, so KWin persists per-output config (scale/mode) by name in kwinoutputconfig.json and reapplies that client's scaling on reconnect — the KDE scaling ask. Also fixes the latent clash where two concurrent sessions both used Virtual-punktfunk (topology name-matching now uses the per-slot name). - identity::global() + resolve_slot(fp, mode, default) — the shared persisted map (Windows manager dropped its own field; both use the global — never same-process). Default identity is per-platform: PerClient on Windows, Shared on Linux, so unconfigured hosts keep today's behavior (Linux = single 'punktfunk' name). - KwinDisplay carries the client fp (set_client_identity), computes the per-slot name, threads it through the stream_virtual_output name + the topology helpers (set_custom_refresh / apply_virtual_primary[_only] / other_enabled_outputs).

enricobuehler	b150d79626	feat(vdisplay): platform-neutral identity map + per-client-mode (Stage 3) ... Generalize the Windows-only per-client stable-id map into vdisplay/identity.rs: - DisplayIdentityMap keyed on a composable string (identity_key: fingerprint, or fingerprint+resolution under per-client-mode); LRU at 15, persisted to display-identity.json (migrated from the legacy pf-vdisplay-identity.json). - Windows manager wired to it, picking the key from the identity policy. - Foundation for KWin per-slot output naming (persistent KDE scaling) — the KWin wiring is the next Stage-3 step (needs a KWin box). - Unit-tested (stable, per-client-mode split, LRU, key composition).

enricobuehler	cb7ddc0411	feat(vdisplay): topology decoupling — distinct primary level (Stage 2) ... The three topology levels become distinct behaviors (Stage 0 only did extend-vs-exclusive, faking primary): - vdisplay::effective_topology() -> the concrete level (console policy > legacy *_VIRTUAL_PRIMARY env > Auto default). Backends read it directly at create time; apply_session_env no longer writes the boolean env (one fewer connect- path env mutation). - Mutter: extend (no config), primary (virtual primary + physicals kept as secondaries — build_primary_keeping_physicals), exclusive (sole, physicals disabled). KWin: extend (no-op), primary (kscreen primary only), exclusive (primary + disable others). - Windows should_isolate treats primary as isolate (the primary-only CCD variant is a follow-up); wlroots exclusive + the physical-keep effect need a display-attached box (headless lab boxes can't observe primary vs exclusive).

enricobuehler	60816709c4	fix(vdisplay): call life.acquire() outside debug_assert (release no-op) ... The pooled entry's lifecycle transition was inside debug_assert_eq!, whose arguments don't evaluate in release builds — so acquire() never ran, the entry stayed Idle, and release saw Noop → immediate teardown (no keep-alive).

enricobuehler	783c52dfad	feat(vdisplay): Linux keep-alive pool — registry-owned display lifecycle (Stage 1b) ... The ownership split (design/display-management.md §3): the registry owns the per-session virtual-display lifecycle on Linux, so a display can outlive its session (keep-alive) and be reused on reconnect. - registry.rs: a Linux pool driven by the pure lifecycle machine. acquire() reuses a kept (lingering/pinned) display of the same backend+mode, else creates one and keeps the backend's keepalive so the compositor output (and its PipeWire node_id) survives the session. The session's capturer holds a gen-stamped DisplayLease instead of the real keepalive; its drop drives linger/teardown. Enabling fact: KWin/Mutter/gamescope put their node on the DEFAULT PipeWire daemon (remote_fd=None) — reconnect re-attaches by node_id, no fd re-open. wlroots (remote_fd=Some, xdpw portal) passes through unchanged (teardown-on-drop) pending the fresh-portal-capture re-attach. - Default (unconfigured) linger = Immediate → today's teardown-on-disconnect, so no behavior change without a keep-alive policy; concurrent sessions still each create their own output (reuse only matches LINGERING entries). - Wired build_pipeline (punktfunk1) + gamestream through registry::acquire; capture_virtual_output signature unchanged. Windows delegates to vd.create (the manager already leases) — unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-04 23:37:21 +00:00

enricobuehler	87f0ce7997	feat(vdisplay): lifecycle state machine + display state/release API (Stage 1) ... Stage 1 of design/display-management.md — the lifecycle core + the display management surface: - vdisplay/lifecycle.rs: pure per-slot state machine (Idle/Active{refs}/ Lingering{until}/Pinned) with acquire/release/expiry/force-release transitions. No I/O, no OS types — the platform-neutral distillation of the Windows manager's model. Unit + a 200k-iteration seeded property walk (no leaks / double-frees / refcount underflow across arbitrary interleavings). - vdisplay/registry.rs: neutral snapshot/release facade over the per-OS lifecycle owners. Windows reads/controls the VirtualDisplayManager; Linux keep-alive (a per-session pool) lands in a following increment (needs GPU-box validation). - windows/manager.rs: additive snapshot() + force_release() (no behavior change to the on-glass-validated path). - mgmt: GET /api/v1/display/state (live/kept displays) + POST /api/v1/display/release (tear down lingering/pinned now; refuses active). OpenAPI regenerated. - web console: Virtual displays card gains a live-display list (polled) with per-row + release-all buttons and a linger countdown.

enricobuehler	bbd98241e4	feat(vdisplay): display-management policy surface (Stage 0) ... A user-configurable policy layer above the per-compositor VirtualDisplay backends: keep-alive, topology, conflict, identity, layout, max-displays — persisted to display-settings.json, editable from the web console, applied per connect. Design: design/display-management.md. Stage 0 stands up the surface and wires the two behaviors the existing code can already express — the Windows monitor linger duration and the "make the streamed output the sole desktop" topology — through it; every other option is stored + echoed but not yet enforced (later stages). An unconfigured host (no display-settings.json) keeps today's exact behavior. - vdisplay/policy.rs: pure DisplayPolicy + 5 presets + JSON store (gpu-settings pattern) + EffectivePolicy; 9 unit tests. - vdisplay.rs: resolve_topology(Auto); apply_session_env drives *_VIRTUAL_PRIMARY from the policy only when a settings file exists. - windows/manager.rs: linger_ms() + should_isolate() read the policy when configured. - mgmt: GET/PUT /api/v1/display/settings (bearer-only); PUT rejects keep_alive forever until the lifecycle stage. OpenAPI regenerated. - web console: Host → Virtual displays card (preset picker + custom fields); en+de. - docs-site: virtual-displays.md + configuration.md cross-links.

enricobuehler	7930d2f0f4	fix(core): split WIRE_VERSION from ABI_VERSION — new clients locked out of every deployed host ... ABI_VERSION was doing double duty: the embeddable C surface AND the punktfunk/1 Hello/Welcome version that hosts equality-check. The WoL feature's v3 bump added a client-local FFI function without changing a single wire byte — and every new client started refusing against every deployed host ("ABI mismatch: client 3 host 2", observed live Deck → Bazzite). The wire now carries its own WIRE_VERSION (still 2); ABI_VERSION stays 3 for the C header and the mgmt API's informational field.

enricobuehler	22c0d92f2e	feat(core,host): Wake-on-LAN sender + host MAC advertisement ... Add a runtime-free Wake-on-LAN sender in punktfunk-core (per-interface subnet-directed broadcast + 255.255.255.255 on ports 9/7, repeated, optional last-known-IP unicast) exposed both as a Rust fn and a punktfunk_wake_on_lan C-ABI (ABI v3), plus a parse_mac helper. The host enumerates its wake-capable NIC MAC(s) and advertises them in a new mDNS `mac` TXT record (routed NIC first), and best-effort detects & warns (never modifies) when the NIC isn't armed for WoL. MAC delivery is via the unauthenticated mDNS TXT rather than the connection handshake by design: a spoofed MAC only makes a wake fail (the packet is inert; the cert fingerprint still gates the connection), and it avoids threading through the hot connect path.

The Steam-conflict gate scanned /sys/bus/hid/devices for non-virtual 28DE devices, but the usbip/gadget virtual Decks present a REAL USB device (vhci resolves through vhci_hcd, not /devices/virtual/) — so a just-ended session's pad still detaching, or a concurrent session's live one, read as "physical Steam controller attached" and degraded every back-to-back Deck session to DualSense (observed live on Bazzite). Exclude our pads by their PFDK… serial (HID_UNIQ), with the vhci_hcd path as belt and braces. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-04 11:14:24 +00:00
enricobuehler	5310176ab5	fix(client-linux,host): Deck video defaults to software decode + input-interception diagnostics ... Video (Deck): the VAAPI zero-copy path renders corrupt/gray/washed-out on the Deck — root-caused to Mesa >= 25.1 exporting radeonsi VCN decode surfaces TILED (the Flatpak runtime's Mesa 26 drives both the decoder and GTK's GL, and GTK's tiled-NV12 dmabuf import mishandles it; desktop Tier-1 validations ran distro Mesa with linear export). `auto` now resolves to software on a Deck (clean, correct-colour, easily handles 1280x800 HEVC); PUNKTFUNK_DECODER=vaapi still forces the hw path, with the descriptor modifier dump + GSK_RENDERER as the bisect levers. Also reserve extra_hw_frames=4 on the VAAPI decoder: the presenter pins mapped surfaces past receive_frame, and the fixed pool recycling a surface the renderer still samples is intermittent block corruption anywhere. Input (Deck): with Steam Input ON for Punktfunk, SDL sees only Steam's virtual X360 pad — the right trackpad arrives as a plain right stick and the left trackpad/paddles/gyro not at all, silently. The client now checks once the post-attach enumeration settles and raises a toast + warn naming the fix (disable Steam Input for the shortcut). The host logs a one-shot warning when InputPlumber is running (Bazzite default) since it can grab the virtual Deck pad and re-emit it under a different identity.

enricobuehler	00acf5e44e	fix(host/audio): WASAPI virtual mic — port the priming jitter buffer (crackling fix) ... Mac → Windows mic passthrough crackled heavily while the identical stream was clean on the Linux host. Cause: clients push mic audio in BURSTS on their own clock (the Mac input tap yields ~two 20 ms Opus packets every ~42 ms) while the WASAPI render loop pulled a block every ~10 ms device period and greedily drained whatever was queued, padding the rest with zeros — the queue sat near-empty and most periods inserted mid-stream silence. The Linux backend has absorbed this since day one with its priming jitter buffer; the WASAPI loop had none. Port the same semantics: emit silence until ~48 ms is buffered (covers the worst inter-burst gap), then play from the cushion (zero-filling only a momentary shortfall), re-prime only after a genuine full drain (client went quiet). Queue cap raised 80 → 120 ms for burst headroom; steady-state added latency ≈ the 48 ms cushion. Diagnosed live on .173: probe tone recording from CABLE Output proved the endpoint wiring, then the burst-vs-period math explained the crackle. Build-verified on Windows; on-glass listen pending.

enricobuehler	449a67ce8d	feat(protocol): per-AU host-timing plane (0xCF) — split host+network latency (stats phase 2) ... The unified-stats equation's host+network stage was one opaque number because the wire carried nothing but pts_ns. Now the host reports its own share per frame: when the client's Hello sets VIDEO_CAP_HOST_TIMING (0x08), the send thread emits a 13-byte 0xCF datagram — [tag][pts_ns u64][host_us u32] — right after the AU's last packet leaves the socket, so host_us = capture→fully-sent (capture read/convert, encode, FEC+seal, paced send) against the same anchor the wire pts carries. Clients correlate by pts_ns and derive network = (received + clock_offset − pts) − host_us; the two terms tile per frame by construction. Back-compat is free in all four combinations: old clients ignore unknown datagram tags, old hosts ignore unknown cap bits (client keeps the combined stage). The hardened data-plane format is untouched — this rides the established QUIC side-plane pattern (0xC8…0xCE). NativeClient ORs the bit in unconditionally and exposes next_host_timing(); the C ABI gains PunktfunkHostTiming + punktfunk_connection_next_host_timing (additive). The synthetic host emits 0xCF too, so pure-loopback protocol tests cover the plane. The probe reports the split (host_p50/p95_us · net_p50/p95_us) and is our direct analogue of Sunshine's "host processing latency" — ours additionally includes the paced send. Validated on loopback (synthetic host + probe, debug build): 240/240 AUs matched, host_p50 6.5 ms + net_p50 6.4 ms ≈ capture→received p50 13.0 ms. Core suite + new 0xCF roundtrip/truncation test green; host+core+probe clippy clean. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-03 21:22:12 +00:00
enricobuehler	09a5957c6d	feat(clients): unified stats vocabulary across every client + Moonlight comparison docs ... One stat model everywhere (design/stats-unification.md): four measurement points (capture/received/decoded/displayed), three stages that tile the interval exactly, and a HUD that shows the addition explicitly — end-to-end 14.2 ms p50 · 19.8 p95 · capture→on-glass = host+network 9.8 + decode 2.1 + display 2.3 replacing each client's ad-hoc mix of overlapping absolutes (the Apple HUD's three arrow lines that looked sequential but weren't), mean-vs-median decode times (Windows/Linux), missing same-host-clock flags (Windows/Linux), and three different names for the same capture→received measurement (probe's "reassembled", Apple/Android's "client", Windows/Linux's post-decode "lat"). Per client: Apple threads receivedNs through the VT decode via the frame refcon bit pattern so the decode stage exists at all (stage-1 fallback honestly degrades to a capture→received headline); Windows carries FrameTimes through the existing frame channel to the render thread and adds e2e p50/p95 post-Present; Linux stamps received at AU pop and rides decoded_ns on DecodedFrame to the paintable-set site; Android pairs receipt stamps with MediaCodec output buffers via the codec's pts round-trip (JNI stats array 14→16 doubles, indexes 0-13 unchanged). fps now uniformly counts received AUs; lost/(received+lost) per window, hidden at zero. docs-site gains "Understanding the Stats Overlay": what each line means, why the equation only approximately sums (percentiles), and a line-by-line Moonlight/Sunshine matrix — including that Moonlight has no end-to-end number and its "network latency" is an ENet control RTT, so punktfunk's headline must not be compared against any single Moonlight line. Verified here: linux client + probe + core check/clippy/fmt green, android native cargo-ndk arm64 check green. Pending: Windows CI + on-glass, swift test on the mac, on-device Android.

enricobuehler	c7630ff5dc	fix(host/audio): mic pump — open handshake on Linux + rapid-death backoff ... Found by a live boot-order test (host started before the user session's PipeWire): PwMicSource::open returned Ok before the daemon connection was attempted, so a PipeWire that wasn't running surfaced as an instantly-dead instance instead of an open failure — and the pump churned open→die→reopen at heartbeat rate (1 Hz "virtual mic ready" log spam) instead of backing off. - PwMicSource::open now has a bring-up handshake (mirrors the Windows backend): ready only after connect + stream connect succeed, so a down daemon is an open ERROR and the pump's backoff engages. - The pump triages deaths: an instance that lived >= 5 s (a one-off daemon restart) reopens immediately with the backoff reset; one that died right after opening counts as a failed open and backs off (2 s → 60 s cap). New pump test rapid_death_backs_off. Re-validated live: host started with PipeWire stopped → throttled "unavailable" warns, zero churn; daemon started → mic node up on the next retry; exactly one pump + one loop thread (no leak).

enricobuehler	2c7ded0f3c	fix(host/audio): rebuild mic passthrough — eager, self-healing virtual mic on both hosts ... Mic passthrough silently died on real hosts. Root causes, all fixed: - No liveness anywhere: a PipeWire restart (Linux) or any WASAPI device error (Windows) killed the backend worker; push() fed the dead queue for the rest of the host's life. VirtualMic now has a liveness contract (push -> bool, alive(), discard()) and the new shared audio::MicPump reopens with backoff, probing on an idle heartbeat so the mic heals BETWEEN sessions too. Validated live: systemctl restart pipewire -> node back in ~0.5 s, tone flows through the reopened backend. - Lazy creation: the mic device didn't exist until the first 0xCB frame, but games bind their capture device at launch and never re-follow. The pump opens eagerly at host start (node exists with zero clients, elected default source). - Windows headless dead-end: with VB-CABLE as the ONLY render endpoint (exactly what the installer ships), the anti-echo guard rejected the cable as the default render endpoint -> mic permanently dead. The new wiring_plan (pure, unit-tested on every platform) assigns the mic its endpoint FIRST (cable reserved for the mic), points the loopback at a DIFFERENT endpoint, and the capture side now yields (explicit endpoint or honest error) instead of the mic dying. Plan recomputed per (re)open — endpoints churn at boot/logon/driver installs. - Stale bursts: buffered audio from a previous session played into a newly-attached recorder (observed live). Timestamped chunks + a consumer-gap check in the process callback age everything past 1 s. The Linux node mechanism stays the stream-based Audio/Source with RT_PROCESS + priority.session: the canonical null-audio-sink adapter recipe was tested on this box (PipeWire 1.6.2) and never gets a clock (QUANT 0 -> pure silence), and WirePlumber reroutes a feeder targeting it to the default sink (echo). Decision documented in the module docs. Live-validated on this box (synthetic host + probe --mic-test, pw-record): eager node, both attach orderings, PipeWire-restart self-heal, post-session silence. Windows side compile/CI + on-glass validation pending. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-03 20:41:19 +00:00
enricobuehler	b7048446c4	fix(windows-host): IDD-push compose kick — idle desktop no longer fails the attach gate ... DWM presents a display only when something dirties it. On an idle desktop a perfectly healthy session sat at E_PENDING: the driver attached but no first frame ever landed, so wait_for_attach's 4 s gate failed the open (and a mid-session ring recreate hit the same stall against the 3 s recover-or-drop). A real client escaped only because its own input soon dirtied the desktop; a headless probe / input-less connect never did. kick_dwm_compose() injects two net-zero 1 px relative mouse moves via SendInput — pf-vdisplay has no hardware-cursor plane, so a cursor move is composited into the frame, a guaranteed real present onto the IDD swap-chain (the mechanism --input-test always relied on; the pointer ends where it started). Wired into wait_for_attach (first kick at 600 ms, then every 800 ms) and, rate-limited, into the GB1 recovery window. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-03 19:24:57 +00:00
enricobuehler	3f33ed30ae	fix(windows-host): claim the vdisplay single-instance guard eagerly at serve startup ... On-glass the lazy (first-session) claim let a second host started while the freshly-restarted service sat idle win the mutex and ADD a monitor on the real driver — priority backwards. The claim is now a process-global, retryable slot (a failed claim is not memoized, so it heals once the other instance exits), and `serve` claims it before any client can connect; ensure_device keeps the lazy claim for standalone punktfunk1-host runs.

enricobuehler	7e31020c1c	fix(windows-host): second-host guard — classify ACCESS_DENIED on the instance mutex as in-use ... On-glass the SCM service creates Global\punktfunk-vdisplay-manager as SYSTEM, so a second elevated-admin host's CreateMutexW fails ACCESS_DENIED (the implicit open is checked against the SYSTEM DACL) before the ALREADY_EXISTS branch can fire — right refusal, wrong message.

enricobuehler	fe54aff658	fix(windows-host): cross-plane IDD serialization, linger-expiry race, second-host guard ... Batch C of the audit's medium tier (M7+M8+M9): - M7: GameStream sessions now run the same begin_idd_setup dance as punktfunk/1 before creating the shared monitor. A GS connect could previously ADD/reconfigure the monitor while a native session was mid-build (and vice versa), and its sealed-channel delivery replaced the native ring (newest-wins) — each plane could freeze the other. GS has no cooperative stop plumbing, so it registers a flag nobody reads: a later session signals it, waits the 3 s grace, then force-preempts — the intended handover. - M8: the linger-expiry teardown now runs UNDER the state lock. Running it outside let a concurrent acquire see Idle and ADD+isolate while the old monitor's pinger-join / CCD-restore / REMOVE were still in flight — a failed or de-isolated session exactly at the expiry boundary. A racing acquire now waits the few teardown seconds instead. Lock order stays state → device everywhere; the pinger takes only the device lock. - M9: a named mutex (Global\punktfunk-vdisplay-manager) makes a SECOND host process fail its vdisplay open loudly instead of firing a startup CLEAR_ALL that razes the live host's monitors mid-stream (the admin footgun the shared watchdog then masked).

enricobuehler	20f0d2802f	feat(client/android): Snapdragon latency tuning — ADPF pipeline hints, game mode, max-clock decode ... Three levers to lower and steady decode latency on Snapdragon (Adreno) devices: - ADPF (Adaptive Performance Framework): a new dlsym-resolved hint session (native/src/adpf.rs; API-33+, resolved at runtime so there's no build-time link dependency and libpunktfunk_android.so still loads on API 31/32) tells the CPU governor the video pipeline runs a per-frame real-time workload, so it keeps those threads on fast cores at high clocks. It now covers all three latency-critical threads — the pf-decode feed/drain/present loop, the core data-plane pump (UDP receive + FEC reassembly), and the audio thread — via a new generic hot-thread registry on NativeClient (register_hot_thread / hot_thread_ids; the pump self-registers). The session is built lazily on the first presented frame, since ADPF createSession rejects a set containing any not-yet-live tid. - operating-rate -> Short.MAX ("as fast as possible"): pushes the Qualcomm decoder to run each frame at max clocks instead of merely sustaining the display rate at a power-saving clock that adds per-frame decode latency. - appCategory="game": makes the app eligible for OEM Game Mode / Game Dashboard performance profiles. The core registry is cross-platform (gettid on Linux/Android, a no-op elsewhere) — no Android-specific pollution of the shared core. Host workspace + 64 core tests green; Android arm64-v8a + x86_64 (platform 31) build + clippy clean. On-device Snapdragon validation pending.

enricobuehler	6f8fb15c9b	fix(windows-host): self-heal the hostless-zombie pf-vdisplay device (adapter cycle + re-probe) ... Fault-injection on-glass showed a killed/crashed WUDFHost leaves the devnode "started" but HOSTLESS: PnP Status OK, no WUDFHost process, zero device- interface instances — is_available() then fails every future session at the vdisplay::open gate (and a reopen inside VdisplayDriver::open finds nothing), until something cycles the device. Port reset-pf-vdisplay.ps1's adapter disable→enable step in-process (restart_vdisplay_device): the open gate now uses ensure_available() (cycle once + bounded re-probe; a genuinely uninstalled driver — no adapter devnode — still fails fast), and VdisplayDriver::open retries open_device over a short arrival window after a cycle, covering the manager's reopen path too.

enricobuehler	89455032a0	fix(windows-host): IDD-push resilience — driver-death recovery, reopenable control device, full interface discovery ... Batch A of the audit's medium tier (M1+M2+M3): - M1 driver-death detection: a dead WUDFHost stops publishing, which at the ring is indistinguishable from an idle desktop — SDR sessions streamed a frozen frame forever (next_frame's 20 s bail is unreachable once anything presented). The ChannelBroker's process handle now doubles as a liveness probe (SYNCHRONIZE at OpenProcess); while no fresh frame arrives, try_consume polls it (rate-limited) and fails the capturer, landing in the session's bounded in-place rebuild. - M2 reopenable control device: the manager's OnceLock-cached handle is now a retire/reopen DeviceSlot — a gone-classified IOCTL failure (driver upgrade / WUDFHost restart; pinger, create, or REMOVE) retires the handle and the next use reopens + re-handshakes. Retired handles are deliberately kept alive forever: bare-HANDLE holders (pinger, ChannelBroker) rely on never-closed, and a retired handle only fails IOCTLs. CLEAR_ALL runs on the FIRST open only (a reopen races live-ish sessions); acquire retries the monitor create once after a reopen. The JOIN path now probes the active monitor's WUDFHost pid and preempts a DEAD monitor instead of handing the rebuilding session its stale target — without this the whole recovery chain starved to the rebuild budget. - M3 interface discovery: enumerate ALL interface instances with an SPINT_ACTIVE filter (a Code-10 devnode at index 0 no longer shadows the live interface), HDEVINFO behind RAII (error paths leaked one per probe), the raw device handle wrapped before GET_INFO (leaked on handshake failure), and the detail-sizing result guarded before the cbSize write. - pf-driver-proto: SetFrameChannelRequest doc now states the real adopt-on-success contract (the old wording invited a driver-side close-on-error — a cross-process double-close against the host's reap). - install: pf_vdisplay_present() passes /connected so a phantom devnode can't suppress creating a live ROOT node.

enricobuehler	0da9d8ec10	fix(windows): IDD-push audit highs — keyed-mutex timeout, two per-frame leaks, IDD_PUSH knob, pooled-device threading ... Five verified findings from the IDD-push/pf-vdisplay deep audit: - Keyed-mutex acquire (BOTH endpoints): AcquireSync returns WAIT_TIMEOUT (0x102) / WAIT_ABANDONED (0x80) as SUCCESS-severity HRESULTs, which the windows-rs Result wrapper erases — a busy slot read as "acquired", so driver and host could race the same ring texture (torn frames) and the designed busy-skip backpressure was dead code. Both sides now classify the raw vtable HRESULT; WAIT_ABANDONED counts as acquired (ownership transfers — refusing it would wedge the slot forever). - Host SDR hot path leaked one ID3D11VideoProcessorInputView per converted frame: the D3D11_VIDEO_PROCESSOR_STREAM ManuallyDrop field suppressed the release after VideoProcessorBlt. Released by hand now, success or not. - Driver leaked IddCx's per-acquire surface reference (from_raw_borrowed on a TRANSFERRED reference — the MS sample Attach/Reset's it): the swap-chain surface set survived swap-chain destruction, the likely true root cause of the ~50 MB-per-reconnect VRAM loss that device pooling only mitigated. Now adopted via from_raw (publisher or not) and dropped pre-Finished. - PUNKTFUNK_IDD_PUSH removed: capture is unconditionally IDD-push, but the vdisplay manager still gated the lingering-monitor preempt (and render pin) on the knob, whose default was OFF — dev/CLI runs reused a lingering monitor whose IddCx swap-chain is dead (black reconnect). The preempt and the render-GPU pin are now unconditional; host.env comments no longer promise the removed DDA/WGC fallback. - Driver D3D device: dropped D3D11_CREATE_DEVICE_SINGLETHREADED (unsound since DEVICE_POOL shares one device across processors) and the pooled immediate context is now SetMultithreadProtected — two concurrent monitors' workers otherwise race an unlocked context (UB in the UMD). No wire-contract change (pf-driver-proto untouched); the driver fixes take effect on the next pf-vdisplay redeploy. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-03 16:27:13 +00:00
enricobuehler	f204a89cef	perf(encode/windows): AMF quality=speed + bf=0; drop the useless poll spin ... On-box A/B on the .173 Ryzen 7000 iGPU (720p60, real composition via input injection — an idle virtual desktop composes ~1 fps and gives meaningless encode timings): the encode-time-first `quality=speed` preset + explicit `bf=0` cut host-side encode_us from ~36 ms to ~19.5 ms. The blocking-poll idea from the prior commit was WRONG and is reverted to a single non-blocking receive (default PUNKTFUNK_FFWIN_POLL_MS=0): libavcodec's hevc_amf holds ~2 frames before releasing the oldest (needs frame N+2 to flush N), so a spin between submits provably never yields the owed AU — verified with a 150 ms cap pegging at exactly 150 ms across every usage preset and pipeline depth. That ~2-frame buffer is inherent to the libavcodec wrapper, not host scheduling; the real latency lever is a direct AMF SDK encoder (the AMF analogue of the direct-NVENC path), tracked as the next AMD work item. The env knob is retained for a future VCN/driver where a bounded spin can help. Also measured and rejected: PUNKTFUNK_ZEROCOPY=1 on AMF is ~2x WORSE (68 ms vs 36 ms) — the D3D11 import path adds sync overhead beyond the readback it saves, so the system-memory default stays. GPU-priority elevation is already process-wide (dxgi.rs), so it covers the iGPU encode session with no change. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-03 14:57:39 +00:00

enricobuehler	51a6ca7e02	fix(encode/windows): AMF latency — honor the loop's blocking-poll contract + preset polish ... The session loop's pipeline deferral was designed around direct NVENC, whose poll() BLOCKS in lock_bitstream; libavcodec's AMF wrapper is truly async (EAGAIN until the ASIC finishes), so a single non-blocking receive quantized AU retrieval to the submit cadence: +1–2 frame periods flat (~43 ms p50 at 720p60 on the Ryzen iGPU vs ~3.5 ms of actual encode). FfmpegWinEncoder now tracks in-flight frames and, while an AU is owed, spin-polls with short sleeps bounded to ~2 frame periods (an overloaded encoder degrades to next-tick pickup instead of stalling capture). Also: quality=speed (latency-first, iGPU-class VCN), explicit bf=0 (h264_amf defaults >0 on RDNA3+), AMF low-latency submission mode (FFmpeg ≥6.1, ignored on older).

enricobuehler	b9fde03f1e	feat(security): finish Windows firewall Public opt-in wiring + vuln-disclosure + doc cleanup ... Firewall (the service.rs core landed in efb1ba2): scope the web-console rule (TCP 47992) to Domain+Private by default with a `--allow-public-network` opt-in that deletes-then-re-adds the rule, and add the installer "Allow connections on Public networks" task (unchecked) forwarding the flag to `service install` and `web setup`. Default is now trusted-networks-only; Public is explicit. Vulnerability disclosure: SECURITY.md (report to security@punktfunk.com, scope, SLAs, safe harbor), a Gitea issue-template contact link, a README security line, and a Reporting section on the docs Security page.

enricobuehler	efb1ba26d7	fix(windows): opt-in pad-driver file logs + size-capped service log rotation ... Two disk-write fixes: - pf-xusb/pf-dualsense no longer write C:\Users\Public\pf*-driver.log unconditionally — the file log is now opt-in (debug builds, or the PFXUSB_DEBUG_LOG / PFDS_DEBUG_LOG system env var), mirroring the audit-§4.4 fix pf-vdisplay already got: a release driver never writes the world-writable Public file (info-leak/DoS surface), and the per-report OUTPUT/SET_STATE hex dumps stop being a sustained per-rumble disk-write path during gameplay. OutputDebugStringA stays unconditional; the host's driver-silence WARN and the gamepad-driver-health failure-mode table now say the log is opt-in. - service.log/host.log get one-generation rotation: at each (re)open a file over 10 MB is renamed to .old, so a crash-restart loop or a RUST_LOG=debug left in host.env can't grow the append-forever logs without bound. Rotation runs only before an open (never under a live appender — host.log's handle lacks FILE_SHARE_DELETE, so a racing rename harmlessly fails). Windows CI compile/clippy pending (drivers workspace + host are not Linux-cross-checkable); rides along with the next pad-driver redeploy.

enricobuehler	8005b11faf	feat(tray): system-tray status icon for the host (Windows + Linux) ... New crates/punktfunk-tray — a small per-user companion showing the host service state at a glance (running / stopped / starting / degraded / failed + the live session in the tooltip) with one-click actions: open web console, approve a pending pairing request, start/stop/restart, open logs. No more digging through logs to learn whether the service came back after a reboot or an update. Status is service-manager-FIRST (SCM / systemd user unit — a port squatter can never fake Running), then the new loopback-only unauthenticated GET /api/v1/local/summary (counts/booleans only; the mgmt token and cert.pem are SYSTEM/Admins-DACL'd on Windows, so a non-elevated tray cannot bearer-auth). Windows: windows_subsystem binary (a console exe in the Run key would flash a terminal at sign-in), Shell_NotifyIcon + hidden window, per-session single instance, TaskbarCreated re-add, --quit for the uninstaller; service actions elevate per click via ShellExecuteW "runas" onto the new `punktfunk-host service restart` (stop → wait Stopped → start). Linux: ksni/StatusNotifierItem over zbus, systemctl --user actions (no polkit), /etc/xdg/autostart entry whose --autostart self-gates to actual host users. Icons: scripts/gen-tray-icons.py (pure stdlib) renders the brand lens + status dot into committed .ico/hicolor assets; deb/rpm/arch ship binary+autostart+icons. Live-validated: Linux on the headless KDE session (SNI registration, state transitions, menu-driven start, dbusmenu layout); Windows on the RTX box (session-1 launch with no NIM_ADD failure, single instance, --quit, restart round-trip, summary loopback-200/LAN-401).
