enricobuehler	40714317a8	fix(web): empty-state cards get their top padding back ... "No games found yet." sat flush against the top edge of its card on any screen ≥640px. The call sites overrode CardContent's padding with a bare `p-8`, but tailwind-merge only resolves conflicts within a variant: `p-8` cancels `p-4` and leaves `sm:p-6 sm:pt-0` standing, so the desktop breakpoint kept the zero top inset that exists for cards WITH a header. These three have none. Uses `flush` — the escape hatch CardContent documents for exactly this — so the padding is owned outright at every breakpoint instead of fought from the outside. The library grid is the one that was reported; the store catalogue and the recordings list are the same idiom with the same bug. PairedDevices deliberately keeps its `p-6`: it is a table under a header, where pt-0 is the intended look.

enricobuehler	188f55d3b1	fix(encode/nvenc): the host advertises what the driver lists, not a superset ... Every NVIDIA host advertised a static H.264|HEVC|AV1 superset, so a 1st-gen Maxwell (GTX 960M, no HEVC/AV1 encode) offered HEVC — a client that believed it got ~15 s of blank video and a disconnect instead of a stream. Both OSes now ask the driver itself (nvEncGetEncodeGUIDs) on one throwaway direct-SDK session: Linux on the shared CUDA context, Windows on the selected render adapter, wired into host_wire_caps AND the GameStream serverinfo mask (which had been left on the superset for NVIDIA on both OSes). Fails open — an unanswerable probe keeps the historical superset, so it can only ever narrow the advertisement to codecs the GPU really encodes. The HEVC 4:4:4 answer rides the same session on Linux instead of opening a libav hevc_nvenc FREXT probe: that open is the prime suspect for the field bug where one probe wedges NVENC process-wide (NV_ENC_ERR_INVALID_VERSION on every later session until a host restart), and the direct backend re-checks the same caps bit at session open anyway. The ffmpeg probe remains only for hosts that really stream over libav (PUNKTFUNK_NVENC_DIRECT=0 or a build without the nvenc feature), where ffmpeg's NVENC client runs regardless. The 10-bit probe deliberately stays libav — Linux HDR rides the libav P010 path. On-hardware: .136 (RTX 5070 Ti) 14/14 nvenc tests in one process incl. the probe followed by real sessions and dirty teardown; .173 (Windows RTX) probe + 47 release lib tests. The Windows probe test documents the pre-existing MSVC debug-link failure (LNK2019 via the sdk crate's unused lazy loader) — run it with --release, the same reason windows-host.yml gates with clippy.

enricobuehlerandClaude Opus 5	560e663aef	fix(drivers): the pad channel asks the devnode who to trust, not the mailbox ... A LocalService principal could take over a virtual pad's shared input section and forge HID input into the interactive desktop. The host duplicates each pad's unnamed DATA section into the driver's WUDFHost, and through gamepad proto v2 it learned that process from `driver_pid` in the named bootstrap mailbox. That mailbox has to be LocalService-writable — that is what the driver's own WUDFHost runs as — and the delivery gate, verify_is_wudfhost, only checks that the target's IMAGE is %SystemRoot%\System32\WUDFHost.exe. That image is world-executable. So anything running as LocalService — notably the deliberately de-privileged plugin runner — could spawn its own WUDFHost (CREATE_SUSPENDED parks it indefinitely with the right image path), publish that pid, and be handed SECTION_MAP_READ|WRITE on a live section. For pf-mouse that section drives a real absolute pointer, so it was desktop control; for the pads it was forged gamepad input plus a read of the remote user's controller state. The module docs claimed mailbox tampering "yields at worst a gamepad DoS, never a read or an injection". That was wrong, and the reasoning behind it — that a LocalService token is DACL-denied OpenProcess on a UMDF WUDFHost — only covers the REAL host, not one the attacker spawned itself. The pid now comes from the device stack (ChannelProof, proto 2 -> 3). The host asks the devnode it SwDeviceCreate'd who is serving it, looked up by the instance id PnP handed back, so a planted look-alike devnode is not a candidate and the kernel — not anything the attacker supplies — does the routing. Only the driver PnP actually bound to that device can answer. `driver_pid` survives as a liveness hint; a tamperer can still deny a pad, which squatting the name always allowed, but can no longer choose the recipient. Two rules keep the state machine honest around it: a delivery stands until its target process EXITS (judged on a retained SYNCHRONIZE handle, so a recycled pid cannot fake it, and UMDF's restart-after-driver-crash still re-attaches), and a pad with no SwDeviceCreate devnode refuses to deliver rather than fall back — unless an operator sets PUNKTFUNK_PAD_CHANNEL_TRUST_MAILBOX, which says so loudly. Three transports, because Windows carries different things to different driver shapes, and the obvious two did not survive contact with hidclass. Measured on .173 (Win11 26200): HidD_GetIndexedString is NOT forwarded to a UMDF HID minidriver at all — it failed for every index including ones the driver demonstrably serves through the named wrappers; and a private device interface registers and enumerates but cannot be OPENED (ERROR_GEN_FAILURE), because hidclass owns IRP_MJ_CREATE on a devnode it is the FDO for. That is exactly why pf-xusb was never affected: it is not a HID minidriver, so nothing sits above it. What works: * pf-xusb — a private IOCTL on its own GUID_DEVINTERFACE_XUSB. * pf-mouse — the HID serial string. Verified: PFCP:3:0:7296, and 7296 was a genuine service-spawned WUDFHost.exe. Safe here alone: nothing reads the virtual mouse's serial, whereas a pad's is SDL/Steam dedup material. * pf-gamepad — a HID feature report, and it cost NO report-descriptor change. The captured descriptors already declare far more Feature ids than the driver ever served: 0x85 is declared on DualSense, DualShock 4 and Edge alike and used to fail with STATUS_INVALID_PARAMETER, so hidclass lets it through and nothing can have depended on the old failure. The Deck's one feature report is unnumbered and Steam drives it command->response, so its proof rides that existing contract via a private two-byte command. Verified: feature 0x85 returned magic "PFCP", proto 3, pad_index 0, wudf_pid 18456 — and 18456 was a WUDFHost — with the product string still 'DualSense Wireless Controller'. Also renamed pf-dualsense -> pf-gamepad. One driver has always served four identities, so the old name read as if the other three lived elsewhere. ONLY the package identity moved (crate, INF/CAT/DLL, UMDF service, build script, CI lines, log file, env var). The four HARDWARE IDS are deliberately unchanged — they bind every devnode the host creates and every installed system — as are the Global\pfds-boot-<i> mailbox and PAD_MAGIC, which are wire contract. `driver install --gamepad` now retires the pre-rename store package first, matched on pf_dualsense.dll because that string appears only in the OLD inf; matching on the hardware ids would delete what we are about to install. On .173 that separated 14 stale packages from the 1 new one with 0 ambiguous, and the renamed package binds the old hwid (devgen root\pf_dualsense -> oem143.inf = pf_gamepad.inf). The repo's own pre-commit/pre-push rustfmt hooks named the old crate, so they caught the rename before the commit did — they now check pf-gamepad, and pf-mouse alongside it, which they had been missing relative to the CI line. Host and drivers MUST ship together: v2<->v3 fails closed in both directions by design, with the existing "update host + drivers together" diagnostic. The rename moved files that also carry the security change, so splitting this into two commits would mean reconstructing an intermediate state that was never gated. It is one commit on purpose. Gated on the windows-amd64 runner with cargo clean first (the box's clock lags, so stale artifacts would read as a vacuous green): clippy -D warnings clean for pf-inject, pf-capture and pf-driver-proto, drivers workspace build + the CI clippy line clean, cargo check --release -p punktfunk-host clean, 19 + 58 tests green. Also fixes pf-mouse still writing its debug log to world-writable C:\Users\Public, which the 2026-07-17 review moved for the other three drivers and missed here.

enricobuehlerandClaude Fable 5	9b3ec9204c	fix(capture): a refused EGL→CUDA dmabuf offer stops being asked ... The raw-dmabuf passthrough has had a negotiation-timeout latch since the hybrid-Intel case: one conclusive timeout and later captures negotiate the CPU path instead of re-paying it. The EGL→CUDA dmabuf-only offer had no equivalent — a compositor that accepts none of the importer's modifiers timed out the same 10 s negotiation on every session, forever, under the generic 'format negotiation never completed' diagnosis. Now the symmetric latch (note_gpu_dmabuf_negotiation_failed) gates build_importer in the one negotiation resolver, scoped to this offer alone (raw passthrough, worker-death latch, encoder untouched), with the same operator escape as the raw arm: an explicit PUNKTFUNK_ZEROCOPY=1 keeps erroring loudly instead of downgrading. One correctness detail beyond the handoff's sketch: whether the GPU offer was ACTUALLY advertised is a runtime fact of the PipeWire thread (the importer may fail to construct — no CUDA — in which case no dmabuf was offered and a timeout must not latch it off). plan.build_importer alone cannot answer that, so the thread records the made-offer on CaptureSignals (gpu_dmabuf_offer) and the timeout diagnosis branches on the offer that really happened, not the plan's intent. Also renames vaapi_dmabuf_forced → zerocopy_forced (it now guards both timeout arms; single caller). New plan invariant pinned in tests: the latch gates only the importer, never the raw passthrough. (V3 from design/pf-zerocopy-sweep-handoff.md — the deferred design call, now decided in favour of the symmetric latch.)

enricobuehlerandClaude Fable 5	e92a0aaa00	fix(zerocopy/vkslot): a timed-out blend can't corrupt its slot, and NV12 cursor chroma sits on the grid ... Two [GPU]-class defects from design/pf-zerocopy-sweep-handoff.md; the code is compile- and unit-verified, the visual halves still owe on-glass time. - blend_ref reused a fence and command buffer after a wait timeout: on TIMEOUT it reset a fence that still had a pending signal and re-recorded a command buffer the GPU might still be executing — reached exactly in the contended case the CPU-synced path exists for (no timeline export + visible cursor + a >1 s GPU stall). A failed wait now drains the device before the reset (the VkBridge::import_linear precedent), and free_slots quiesces unconditionally instead of only when a timeline exists, so teardown after a timed-out sync blend no longer frees objects an outstanding submission references. (C1) - cursor_blend.comp anchored NV12 chroma blocks to the cursor's oy, not the surface chroma grid: for odd oy every UV sample averaged luma rows one below the rows it covers (a one-row colour fringe on the cursor's edges, ~half of all cursor positions) and the cursor's last row's chroma was never written. Block rows now anchor to the chroma grid the same way spans anchor to the word grid — y0 = floor(oy/2)*2, per-row cy guards for the straddle block — and blend_geometry counts blocks from the same anchor (one extra block when oy is odd; covered by new tests, including negative oy). cursor_blend.spv rebuilt (glslangValidator, spirv-val clean, drift gate passes). (C6) Owed on-glass: a stalled-GPU cursor session for C1; an odd-oy cursor colour check for C6 (subtle fringe on the cursor's top/bottom edge).

enricobuehlerandClaude Fable 5	fa083f50d3	fix(zerocopy): unsafe fn bodies join the unsafe-proof program ... #![deny(clippy::undocumented_unsafe_blocks)] never inspected the body of an unsafe fn — operations there are not "unsafe blocks" — so roughly 20 functions' worth of raw GL/CUDA/Vulkan driver calls sat outside the invariant the crate advertises. Concretely, that blind spot is why the constructor-leak and teardown-ordering shapes fixed earlier in this series could ship without ever prompting a reviewer. #![deny(unsafe_op_in_unsafe_fn)] now closes the gap: every unsafe fn body is an explicit unsafe block carrying a SAFETY comment that names the caller contract it relies on (the dlopen'd CUDA wrapper table gets a uniform forward-to-live-table proof). Mechanical; no behavior change. (V2 from design/pf-zerocopy-sweep-handoff.md.) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-28 12:59:15 +02:00
enricobuehlerandClaude Fable 5	c677732c60	fix(zerocopy/client): a wedged worker can't park the reaper, and no worker outlives the host ... Three related reaper problems (R5 from design/pf-zerocopy-sweep-handoff.md): - sweep_reaper called kill() + blocking wait() while holding the global REAPER mutex. A worker wedged in a driver ioctl is in D state and ignores SIGKILL, so wait() never returned — parking every later spawn() and every importer drop() behind the lock. Expired entries are now drained under the lock and killed outside it, with a bounded (~100 ms) try_wait poll; a worker that still won't die is parked again for a later sweep (re-killing is harmless) instead of blocking anyone. - No PR_SET_PDEATHSIG: if the host died, the worker survived holding its CUcontext + BufferPool — by the code's own comment, hundreds of MB of VRAM. The pre_exec closure (async-signal-safe: prctl/getppid/dup2/fcntl only, no allocation) now arms SIGKILL-on-parent-death with the standard getppid race guard. Not taken: arming the 20 s kill deadline from a timer instead of the next spawn/drop (the handoff's optional third leg). PDEATHSIG closes the worst-case orphan; a wedged worker after the LAST capture of a session still waits for the next spawn to be swept.

enricobuehlerandClaude Fable 5	3c62da3b8e	fix(zerocopy/client): renegotiation retires the old generation's IPC mappings ... Shared::mappings only ever grew: clear_cache reset sent_keys and told the worker to drop its fd cache, but nothing closed the host-side CUDA IPC mappings for the previous pool generation. A session that renegotiates repeatedly (mode changes, HDR toggles, client reconnects) accumulated a pool's worth of stale mappings each time, each pinning a host VA reservation to peer memory the worker had already freed. Mappings now carry a refcount and a retired flag. clear_cache closes every unreferenced mapping immediately and marks the rest retired; a retired mapping closes when its last in-flight DeviceBuffer releases. The worker's half of the contract: ClearCache also forgets its VA→id map, so anything delivered after the boundary gets a fresh id WITH its descriptor — without that, a same-shape renegotiation (worker keeps its pool) would re-deliver an old id whose host mapping was just closed, and the host would misread it as a desync. Ids never repeat (next_id only counts up), so fresh ids cannot collide with the graveyard. (R6 from design/pf-zerocopy-sweep-handoff.md.)

enricobuehlerandClaude Fable 5	a2033d6c82	fix(zerocopy/vulkan): VkBridge bring-up and the CSC build unwind instead of leaking ... VkBridge::new leaked its instance (and past device creation, the device and command pool too) on every error path — reached repeatedly, because a box whose Vulkan device refuses the external-memory extensions retries the bridge on every LINEAR frame. Pre-device failures now destroy the instance explicitly (the VkSlotBlend::new shape); after device creation the remaining objects build into an incrementally-filled struct whose existing Drop tolerates the nulls a partial init leaves (Vulkan destroy calls are defined no-ops on VK_NULL_HANDLE). ensure_csc had the same hole across its six-object pipeline build; the fallible half now fills the Csc front to back and a mid-build failure destroys exactly what was created, leaving self.csc None for a clean retry. (R3 from design/pf-zerocopy-sweep-handoff.md.) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-28 12:49:42 +02:00
enricobuehlerandClaude Fable 5	8d02255703	fix(zerocopy/egl): construction can fail late, so teardown must be structural ... Three unwind holes in the EGL side, all of the same shape — fallible construction over raw handles with no Drop to unwind through — and all retried per frame, so a sustained failure (VRAM pressure is the realistic one) leaked unboundedly: - The GlBlit/Nv12Blit/Yuv444Blit constructors interleave GL-object creation with fallible steps (FBO completeness, CUDA registration, pool allocation). A GlNameGuard now owns every bare GL name until the final struct exists; on unwind it deletes them AFTER the RegisteredTexture locals unregister (declaration order), preserving the unregister-before-delete invariant. gl.rs gets the same treatment for its compile paths: the vertex shader on a fragment-compile failure, the program on a link failure. (R1) - EglImporter::new leaked the DRM render-node fd and the whole gbm_device on every '?' after their creation (most realistically cuda::context() failing on a host where EGL comes up but CUDA does not). Both now live in a GbmDevice with its own Drop: destroy the device, then close the fd. (R2) - EglImporter's manual Drop destroyed the gbm device and closed the fd BEFORE field drops ran the blit destructors, which then called cuGraphicsUnregisterResource/glDeleteTextures against a dead native display — the stale-driver-state class this path once crashed on. The Drop impl is gone; teardown is now purely field order (blits and bridge first, GbmDevice last), and the blit SAFETY comments cite that order instead of the previously-false claim. (R4) (R1/R2/R4 from design/pf-zerocopy-sweep-handoff.md.) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-28 12:47:54 +02:00
enricobuehlerandClaude Fable 5	8de5ba4092	test(zerocopy): the fd must actually cross the socket, not just claim to ... SCM_RIGHTS descriptor passing is the mechanism the whole worker isolation design rests on, and no test verified it end to end: both suites asserted only the has_fd boolean parsed from the JSON body. Setting the send-site's descriptor to None — zero-copy broken in production — stayed green; so did dropping the received fd in the worker's dispatch loop. Now the client-side scripted peer records the st_ino of every descriptor that arrives and the tests assert the sequence against dmabuf_key() of the sent plane (SCM_RIGHTS re-numbers the fd but preserves the open file description, so the inode is the identity the worker keys its cache on); the worker dispatch test sends one import with a live fd and asserts the backend received a descriptor with the sender's identity.

enricobuehlerandClaude Fable 5	143a707f76	fix(zerocopy): the mechanical sweep batch — truthful fence waits, forgiving env flags, no leaked planes ... From the pf-zerocopy review sweep (design/pf-zerocopy-sweep-handoff.md), the compile-verifiable batch: - dmabuf_fence: the blocking poll's result was discarded — EINTR silently skipped the wait (reopening the stale-frame race a SIGCHLD away) and a timeout reported as waited. Now EINTR retries with the remaining budget and the caller gets Signaled/TimedOut/NoFence, so the one diagnostic operators have about implicit fencing stops lying. (C2) - env flags: PUNKTFUNK_ZEROCOPY=TRUE meant *off* — values are case-folded now, and an unrecognised spelling falls back to the flag's default with a one-shot warning instead of silently inverting the operator's intent. (C3) - cuda: alloc_pitched_nv12 leaked the Y plane when the UV allocation failed (per-frame under VRAM pressure — the worst possible time to leak); a failed async-copy enqueue now drains the stream before returning, so a recycled pool buffer can't race an orphaned in-flight copy. (C4, C5) - worker: --fd is validated (>= 3, fstat + S_ISSOCK) before OwnedFd adoption — 'zerocopy-worker --fd -1' was constructing OwnedFd's niche value. (V1) - docs: all 15 rustdoc warnings fixed, including the link to the renamed note_raw_dmabuf_negotiation_failed. (D1) - CI: a SPIR-V drift gate — the committed .spv blobs are include_bytes!'d and rebuilt by hand; the gate diffs disassembly (filtering only the shaderc/glslang generator difference) so a forgotten rebuild fails CI instead of shipping the old kernel. Both blobs verified in sync. (S1) - tests: bt709_limited pinned to external BT.709 anchors (it is the sole oracle for the GPU colour self-test); blend_geometry gets its first tests — empty rect, CURSOR_MAX clamp, per-format group counts, and negative-ox floor alignment. (T2, T3) Verified on .25: clippy -D warnings clean, 27/27 tests, cargo doc 0 warnings. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-28 12:40:37 +02:00
enricobuehlerandClaude Sonnet 5	c4e80fd455	docs(release): v0.21.0 notes should only cover its own delta ... Duplicated the entire v0.20.1 fix bundle verbatim instead of following house convention (each vX.Y.Z.md covers only what changed since the immediately preceding release file — see v0.19.1 -> v0.19.2, neither restates the other). v0.20.1 is a real, already-tagged release with its own notes file; 0.21.0 only needed to add the monitor-streaming feature, the KDE registry fix found while building it, and the CI-only winget fix, with a pointer back to v0.20.1 for the rest.

enricobuehlerandClaude Opus 5	d08893383a	chore(release): bump workspace version to 0.21.0 ... 42 commits since v0.20.0 (v0.20.1 was tagged but never announced; superseded by this release rather than repointed, since real new functionality landed after it was cut). Minor, not patch: the headline is streaming one of the machine's own physical monitors instead of always creating a virtual display — pick it from a new console card or pin it in host.env, on KWin, Mutter, sway and Hyprland, in both the Punktfunk app and Moonlight. Also folds in the full v0.20.1 fix bundle: three Windows install blockers found within hours of 0.20.0, GameStream/Moonlight compat back to opt-in on fresh installs, three gamescope Game Mode takeover faults, a laptop-panel stall misdiagnosis, and the PyroWave high-bitrate latency-creep bundle — plus a KWin 6.7 regression found while building the monitor feature (silent kscreen-doctor fallback on every session) and a winget release-verification CI fix. Wire protocol stays at 2, the embeddable C ABI at 13 and the Windows virtual-display driver protocol at 6. GET /display/monitors is a new additive endpoint; the display policy gains an optional capture_monitor field. No embedder rebuild required.

enricobuehlerandClaude Opus 5	8fe71be424	fix(web): applying a saved preset kept switching the streamed screen off ... `applyCustomPreset` builds a FRESH policy object instead of spreading the draft, so every field it doesn't name is dropped. `capture_monitor` was not named — so picking one of your own saved presets silently took a host that was mirroring a real monitor and put it back on a virtual display. The same omission in the Custom switch would have done it there too. Found on-glass against a running serve on .136: the PUT is whole-object, so the console is the only thing keeping the orthogonal axes alive, and these two sites were the ones building a policy from scratch rather than from what was already in force.

enricobuehlerandClaude Opus 5	a98174ebfa	feat(host): anchor-test, and libei says which output absolute input landed on ... The absolute-region ladder existed for one case a unit test can only simulate — two heads of the SAME size, where matching a libei region by the streamed mode is a coin flip — and that case had never been run against a real compositor. It was also unobservable: the log said which regions the EIS server offered, never which one a coordinate went into, so "the pointer is on the wrong monitor" could only be discovered by looking at a monitor. libei now reports the chosen region once per distinct answer, beside the existing miss warning: one covers an anchor that named nothing, this one covers an anchor that matched something, by saying which. `anchor-test` is the gate that reads it, in the shape mirror-test established: it enumerates the heads, SAYS whether the rig actually has two of the same size (a green run on a single-head box proves nothing), anchors at a named one (or `--none` for the A/B that makes the anchored run mean anything), and walks the corners. It refuses to run off libei rather than emitting a green result about a ladder that isn't there. On-glass on KWin 6.7.3 with `kwin_wayland --virtual --output-count 2` (regions 1920x1080+0+0 and +1920+0): unanchored picks +0+0, anchored at Virtual-1 picks +1920+0, anchored at Virtual-0 picks +0+0. That is open item 3 of design/per-monitor-portal-capture.md §8b, closed. Clearing the pin now logs too — setting one always did, and the streamed screen going back to virtual is the same size of change.

enricobuehlerandClaude Opus 5	ea0c61fb0f	docs: streaming a real monitor, and the CLI that names one ... The console grew a "Streamed screen" card and the host grew a PUNKTFUNK_CAPTURE_MONITOR knob and a list-monitors command, and the docs knew about none of it — a control with no explanation anywhere. virtual-displays.md gets the feature section: what it is for, that the monitor is never touched, that its resolution wins and a client scales, that a bad name is a hard error rather than a different screen, and that there is no chooser dialog on any of the four backends (which is what makes it work unattended). Plus the three troubleshooting entries the shape of the feature predicts: settings that do nothing while mirroring, a console card the env var has locked, and a pin that names no head. host-cli.md documents list-monitors and mirror-test; configuration.md gets the knob, including that it outranks the console on purpose; running-as-a-service.md gets the desktop-session drop-in and states that the host needs nothing exported to find its session.

enricobuehlerandClaude Opus 5	19deac75fe	feat(packaging): a desktop-login host restarts with its desktop ... The shipped unit's PartOf=punktfunk-kde-session.service covers the APPLIANCE route, where we start the compositor ourselves. A host on a machine somebody logs into has no such unit: when Plasma or GNOME restarts, the daemon keeps running while holding a Wayland socket and a portal D-Bus connection that both died with the old compositor, and it cannot recover either in-process. It fails quietly — the host still listens, still answers, and every session it then serves dies at capture. A host that mirrors a monitor idles for days between sessions, which is the shape that finds this at the worst moment. The drop-in binds the host to graphical-session.target: PartOf takes it down with the session, WantedBy brings it back with the new one. Shipped under /usr/share rather than as an active drop-in, because it is wrong for the appliance route (which may never reach that target at all, and would then leave the host permanently stopped) — the operator opts in.

enricobuehlerandClaude Opus 5	45f04f50fe	test(mgmt): gamescope reports no monitors, and that is not a missing explanation ... /display/monitors must never answer empty AND silent — the console reads that as "the host is broken". But gamescope is nested: it owns no physical heads by construction, so empty-and-silent is the correct answer there, not an unexplained one. Any dev box that has ever been in game mode keeps gamescope-0 sockets in its runtime dir, so detect() resolves gamescope and the test failed on the machine rather than on the code (found running the suite on .136).

enricobuehlerandClaude Opus 5	6afc05155b	feat(vdisplay/session): derive SWAYSOCK — the last session var a --user host lacked ... Session detection already hands every backend the live session's env: WAYLAND_DISPLAY from a socket scan, XDG_RUNTIME_DIR from the uid, the session bus, XDG_CURRENT_DESKTOP, and Hyprland's instance signature. sway was the exception — SWAYSOCK had to be INHERITED from the login shell, so a systemd --user host that never saw one had no sway IPC at all: no output enumeration, no capture chooser, no wlroots backend (its is_available() keys off that very variable). It is derivable, and by identity rather than guess: sway names its socket sway-ipc.<uid>.<pid>.sock, and detection already knows the compositor PID. Ladder: a valid inherited value, then the exact PID's socket, then the newest one we own (a sway re-exec can leave the name pointing at a PID we didn't see). None on river — the other wlroots desktop ships no sway IPC, and saying so is what stops apply_session_env exporting a SWAYSOCK that points at nothing. Closes the session-env half of design/per-monitor-portal-capture.md §6 for a desktop-login host: nothing has to be exported for the host to find its session.

enricobuehlerandClaude Opus 5	829bcb7962	fix(gamestream): the streamed-screen pin applies to the portal source too ... PUNKTFUNK_CAPTURE_MONITOR is documented as "instead of creating a virtual display OR taking whichever head the portal hands back", and the console presents it as a host-wide setting. The compat plane's portal source did neither: it went straight to the chooser, so a Moonlight client on a pinned host silently got whatever screen the portal picked. That is the one outcome the whole feature exists to prevent — showing the wrong monitor is worse than showing none. The portal arm now mirrors the pinned head instead, through the same MirrorDisplay the virtual source reaches via vdisplay::open. It launches nothing and creates no virtual output, so it needs neither the game-lifetime machinery nor the registry (External ownership passes through it anyway). Which screen a pooled capturer is showing is now the third reuse key beside HDR-ness and cursor mode. The pin is a LIVE setting — the console can re-aim the host between two connects — so without it in the key the second connect would keep streaming the previous screen, which is the same silent-wrong-monitor failure by another route (§7.3, open item 5).

enricobuehlerandClaude Opus 5	de3ef50434	fix(native): a mirrored monitor has a fixed mode — refuse to resize it ... A physical head runs at the mode its owner set, and MirrorDisplay::create ignores the requested one on purpose. So a mid-stream Reconfigure against a mirror could only ever tear the cast down and rebuild the identical one at the identical size — a hitch that buys nothing, and an invitation to the worse reflex of reconfiguring the display someone is sitting at. reconfig_allowed grows a third gate beside gamescope and per-client-mode identity, and the session captures it at bring-up like the others: this session opened its display under whatever the pin said then, so a console change mid-session must not retroactively change the answer it gives. Linux-only, because vdisplay::open only routes to the mirror there — a pin left in a Windows host's settings streams nothing different and must not disable resize as a side effect. design/per-monitor-portal-capture.md §7.3, open item 4.

enricobuehlerandClaude Opus 5	b08226dbf1	feat(vdisplay): mirror a pinned monitor on sway and Hyprland ... P5 of design/per-monitor-portal-capture.md, and the end of a hole worth naming: the pin was accepted, persisted and offered in the console while `create` bailed on these two backends, so a sway or Hyprland host with a monitor selected failed EVERY session. Both already ship the mechanism — a managed portal-chooser config plus a per-session selection file (xdpw's `Monitor: NAME`, xdph's `[SELECTION]screen:NAME`) — so mirroring is that same chooser pointed at a physical connector instead of a headless output we created. The keepalive stops the cast and nothing else; the monitor is the compositor's. The selection write is now serialized against the handshake that reads it (SELECTION_LOCK, applied to the virtual-output paths too). That file is one per-user path: whoever writes last before the portal reads wins, and the loser does not fail — it silently captures the other session's output. `managed` is no longer grounds for refusal everywhere. It is conclusive only where the name is ours by construction (KWin's `Virtual-punktfunk`, Hyprland's `PF-N`); sway names EVERY headless output `HEADLESS-N`, its own included, so the old rule would have refused to mirror any output on a headless sway box — exactly the remote setup this feature serves. Found on-glass, and now a test. Verified on a two-output headless sway: asking for HEADLESS-1 yields 1280x720 frames and HEADLESS-2 yields 1920x1080, so the chooser really does steer per request. Hyprland is compile-only — no Hyprland box exists. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-07-27 23:51:41 +02:00
enricobuehlerandClaude Opus 5	d461d889c3	feat: the streamed screen is a persisted setting, pickable from the console ... P4 of design/per-monitor-portal-capture.md. The pin was an env var read once at startup, which a console picker can never write — so it becomes a field of the display policy (orthogonal to presets, like game_session), and `vdisplay::capture_monitor()` resolves env-over-policy: an appliance that pinned in its unit's host.env stays pinned there, and a console click cannot re-aim a machine whose operator already declared the answer. Read per `open` rather than cached, so a picker change takes effect on the next session instead of the next host restart. The host re-resolves the input anchor on every policy write — including clearing it when the pin is cleared, or a later virtual-display session inherits an anchor aimed at a monitor it is not showing. `with_manual_layout` carries the pin through like the other orthogonal axes: without that, saving a display ARRANGEMENT would silently swap the streamed screen back to virtual. Console: a "Streamed screen" card listing the host's real monitors beside "Virtual screen (default)", saving on selection. A disabled head is listed but not selectable (so "why isn't it here?" has an answer), and an env-pinned host renders read-only with the reason rather than offering controls that silently lose to the environment. Verified on GNOME/Mutter: pinning via the policy file alone (no env) routes sessions to the mirror and anchors input; setting the env to a different connector overrides it, exactly as documented.

enricobuehlerandClaude Opus 5	358cfa4be4	feat(host): mirror-test — the on-glass gate for per-monitor capture ... Opens the display backend exactly as a session would, attaches a capturer and reports the frames a named head actually produces, with no client involved. `--monitor` names the head explicitly (it cannot go through PUNKTFUNK_CAPTURE_MONITOR: pf_host_config parses the environment once and startup already read it, so a tool setting it for itself would still see the old snapshot — hence vdisplay::open_mirror); with no argument it exercises the production routing through the pin. A frame timeout is NOT treated as failure. Compositor capture is damage-driven — the host's own capture diag logs new_fps=0 for virtual outputs on an idle desktop for exactly this reason — so the first version of this tool ended its measurement on the first idle gap and made a working mirror look like a 2-frame stall. Verified on KWin 6.7.3 (home-nobara-1), mirroring HDMI-A-1: 346 frames in 20s at 1920x1080, arriving while input was injected and pausing when the desktop went quiet, on both the CPU (BGRx/MemFd) and zero-copy (NV12 dmabuf) paths, ownership=External.

enricobuehlerandClaude Opus 5	045deaf77a	fix(vdisplay/kwin): bind the output-device REGISTRY — KWin 6.7 stopped ... advertising per-output globals Found on-glass while testing monitor enumeration: KWin 6.7.3 advertises kde_output_device_registry_v2 and NOT one kde_output_device_v2 global per output. This module only ever bound the globals, so on a current KWin it saw zero devices. That is not just an enumeration gap — it silently disabled the whole in-process output-management path, which exists precisely because kscreen-doctor wedges. The live 0.19.2 host on the test box logs "kde_output_management unavailable — kscreen-doctor fallback" on EVERY session, so every topology apply there has been going through the tool this module was written to stop using. Both models are supported now: the per-output globals older KWin sends, and the registry's `output` events. Devices from the registry arrive a round later than globals do, so the handshake takes one more barrier — skipped when nothing is still awaiting its `done`, so the classic path costs nothing. Verified on KWin 6.7.3: enumeration now reports HDMI-A-1 1920x1080@60 at +0,+0 scale 1.35 primary, matching kscreen-doctor exactly.

enricobuehlerandClaude Opus 5	bf2f54a5fe	feat(vdisplay): mirror a pinned monitor on Mutter, and scope the HDR probe ... P3 of design/per-monitor-portal-capture.md. Mutter's mirror is the same private ScreenCast session the virtual path already drives, one call different — RecordMonitor instead of RecordVirtual — so it inherits what makes that path work headlessly: a direct D-Bus API that needs no interactive approval, unlike the xdg portal a background service could never answer. Deliberately not under TOPOLOGY_LOCK: that serializes operations which add or remove a monitor or apply a monitor configuration, and mirroring does neither. Nothing is created, no layout changes, and teardown is just Stop — the SIGSEGV-adjacent ordering the virtual path must observe cannot arise when no monitor is being removed. The GNOME HDR probe now honors the pin. Asking "is ANY monitor in BT.2100 mode" was fair while capture took whatever head it was handed; once the operator names one, an HDR TV on the next connector must not talk the host into offering PQ formats for the SDR panel it is actually streaming. A pin that names no live head reports SDR rather than falling back to "any" — the session is about to fail on that same missing monitor, and an over-claimed HDR offer would be a second, quieter wrong answer. ⚠️ RecordMonitor's exact signature is read from the interface, not yet confirmed against a live gnome-shell; no GNOME box was reachable.

enricobuehlerandClaude Opus 5	53c772702f	feat(host): list-monitors CLI, and two bugs it caught on-glass ... An operator configuring an unattended host has to learn the connector names from somewhere, and "curl the management API before the host is configured" is not it. `punktfunk-host list-monitors` prints them with geometry and flags the pinned one. Running it under a real sway immediately caught two defects the unit tests could not: - the query used the `swaymsg` command helper, which inserts `--`, so `-t get_outputs` came back as "Unknown/invalid command '-t'". Queries now go through a `swaymsg_query` helper that cannot make that mistake. - compositors write the literal "Unknown" rather than leaving make/model empty, so the picker label read "Unknown Unknown". One `describe` helper now treats that as absent, for all four backends. Verified on a headless two-output sway: names, modes, positions, scale and the case-insensitive pin all resolve.

enricobuehlerandClaude Opus 5	93c2765db7	feat(vdisplay): mirror a pinned physical monitor on KWin ... P2 of design/per-monitor-portal-capture.md. zkde_screencast's stream_output records an output KWin already has — the connector name IS the selection, so there is no dialog, no portal and no chooser for a background service to answer. It arrives as a VirtualDisplay reporting DisplayOwnership::External, which already means "someone else's display, merely mirrored: no keep-alive, no topology, no reuse". So the rule that we must never disable, move or "restore" a monitor the user is sitting in front of holds by construction rather than by everyone remembering it — and create() ignores the client's requested mode for the same reason: a panel runs at the mode its owner set. Routing lives in vdisplay::open, the one place every session opens a display, so the pin cannot be honored on one plane and ignored on another. The host sets the libei anchor from the same pin (pf-vdisplay must not depend on pf-inject), which is what makes absolute input land on the mirrored head instead of a same-sized neighbour.

enricobuehlerandClaude Opus 5	2eeee650b9	fix(inject/libei): absolute coordinates resolve by identity, not by size ... libei hands the injector one region per logical monitor with no output name attached, so picking one meant matching the streamed mode's SIZE — a coin flip the moment two heads share a mode, and it already resolved wrong on-glass once (GNOME, a dummy HDMI beside the virtual primary: the seat cursor never entered the streamed monitor, so neither cursor path could see it). The ladder is now mapping_id -> origin -> size -> first. Two outputs can share a size but never a top-left, and a mirrored head's region is not the client's size at all, so the size rung cannot find it — this is what makes per-monitor capture land its input on the monitor it is showing. An anchor that matches nothing falls back down the ladder rather than stranding input: the region set is the truth and the anchor is our belief about it. It warns once per distinct anchor, because the failure this exists to prevent is a pointer that silently lands elsewhere. P1 of design/per-monitor-portal-capture.md — mechanism and tests only. Nothing sets an anchor yet; the pin wires it in P2, and the doc comment records why it is host-level and not per-session.

enricobuehlerandClaude Opus 5	95e3314d9a	feat(vdisplay): enumerate the host's physical monitors ... P0 of per-monitor capture (design/per-monitor-portal-capture.md): nothing in the tree could answer "what heads does this host have?", which both a monitor pin and a console picker need first. One read per compositor, each beside the code that already speaks that dialect: KWin's kde_output_device_v2 (the topology session now also records geometry + scale), Mutter's DisplayConfig.GetCurrentState, swaymsg get_outputs, hyprctl monitors. Logical geometry throughout, because x/y is what identifies a head — two monitors can share a size but never an origin. PUNKTFUNK_CAPTURE_MONITOR parses here and is reported at startup, loudly including that it is not yet enforced: a knob that is read but inert has to say so, or "it didn't work" reads as a bug. GET /display/monitors always answers 200 with an explained empty list, so a compositor-less host renders as "nothing to pick", not as a broken console.

enricobuehlerandClaude Sonnet 5	3721b6816d	chore(release): bump workspace version to 0.20.1 ... 24 commits since v0.20.0. Patch, not minor: entirely fixes and hardening on top of last release's session⇄game work, nothing new to opt into. Headline fixes: three Windows install blockers reported within hours of 0.20.0 (a false conflicting-host detection, a broken winget log-path switch, missing package-source instructions), GameStream/Moonlight compat flipped back to opt-in on fresh installs, three gamescope Game Mode takeover faults that could black out a Linux machine or strand it on a host restart, a deactivated laptop panel misdiagnosed as a blind spot instead of a named stall cause, and the PyroWave high-bitrate latency-creep bundle (clock re-sync starvation, wire bitrate overshoot, backlog buildup, ABR probe false-congestion). Wire protocol stays at 2, the embeddable C ABI at 13 and the Windows virtual-display driver protocol at 6, unchanged from 0.20.0 — no embedder rebuild required, 0.18/0.19/0.20 hosts and clients mix freely.

enricobuehler	6be865f33f	fix(host): a host that is stopped hands the box's session back first ... Until now the host had no signal handling at all: SIGTERM killed it outright. That is fine for a host that owns nothing — but a managed gamescope takeover owns the box's session, and on a mask-fragile display manager (Nobara's plasmalogin) it has STOPPED that display manager for the length of the stream. Killed there, the host leaves a box with no graphical session and nothing left to restart it: the crash-restore state lives in $XDG_RUNTIME_DIR, which logind removes along with the user manager, so not even the next host start can heal it. `systemctl --user restart punktfunk-host` mid-stream — or a package update doing it for you — was enough to strand a box until someone reached a VT. So SIGTERM and SIGINT now restore first and exit after. The restore runs on a blocking thread (it shells out) under a 20s grace, well inside systemd's TimeoutStopSec, and a host that took nothing over exits immediately. `restore_takeover_now` is the synchronous sibling of the debounced disconnect restore, and deliberately ignores the keep-alive policy the latter honors: `keep_alive=forever` pins a session for the NEXT client, which means nothing once the host that would serve them is exiting. Both paths now share one `takeover_live()` predicate instead of repeating the four-way "is anything ours" test. Checked on Linux: clippy -D warnings on punktfunk-host + pf-vdisplay, tests, rustfmt.	2026-07-27 19:04:20 +02:00
enricobuehler	f3615f83a5	fix(gamescope): the takeover no longer kills the host it is running in ... Field report, Nobara + 0.20.0: switching into Game Mode mid-stream disconnects the client and the box never lights up again. His journal has the whole mechanism, ten seconds apart: 12:34:18.9 freed Steam: stopped the display manager for this stream 12:34:29.0 systemd[1685]: Stopping punktfunk-host.service Stopping the display manager ends the user's last login session. The packaged host is a `systemd --user` unit, so logind then stops user@1000.service once UserStopDelaySec elapses — 10s by default on Nobara — and takes the host with it. The stream dies, the scheduled restore never runs, and the display manager stays down with nothing left to restart it: a black box that needs a VT to recover. Exactly the two symptoms reported, and the intermittency is just whether an active Gaming Mode session was there to trigger the takeover at all. It never showed on the repro VM because lingering was enabled there for the earlier sessionless tests (`Linger=yes` — confirmed on the VM today), which is precisely the thing that breaks the dependency: logind keeps the user manager alive with no session. Our KDE/GNOME/Arch setup guides already ask for it; his box, following the KDE route, did not have it. So the takeover now ensures lingering BEFORE it touches the display manager: `loginctl enable-linger` directly (allow_active in logind's own policy — verified working unprivileged on Nobara), else the packaged helper gains a `linger` verb that enables it for PKEXEC_UID alone, never a caller-named user. If neither works the takeover is refused with an actionable error and managed degrades to attach — mirroring the box's own session is strictly better than a screen that needs a VT. Hosts that cannot be reached this way (root, a system unit) skip the check: the cgroup test is a pure `cgroup_under_user_manager` with a unit test, matched against the real shapes on a Nobara box (`user@1000.service/app.slice/...` vs a `session-N.scope`). Also documents the requirement in the gamescope guide's Nobara section. Checked on Linux: clippy -D warnings, 78 tests, rustfmt; helper verified with `sh -n`, and the linger enable/disable round-trip run live on the Nobara VM.	2026-07-27 19:04:20 +02:00
enricobuehler	eae1837a3a	fix(gamescope): a managed takeover never waits on a dialog nobody can see, nor acts on a months-old sentinel ... Two ways the Nobara DM-stop takeover could end a session and leave the box dark, both found while triaging a 0.20.0 field report (managed round-trip: "my client disconnects and my monitor doesn't turn back on", intermittent). 0.20.0 is the first release where that box runs the takeover for real — before it, no package shipped the polkit privilege, so managed always degraded to attach and never touched the display manager. Privileged verbs are non-interactive now. `try_stop_display_manager` and `restore_display_manager` try a plain system-bus `systemctl` first, and without `--no-ask-password` that asks polkit for INTERACTIVE authorization. On a box where the host runs inside the user's graphical session, polkit hands that to the session's agent: a password dialog on the box's own screen, which during a takeover is off or mid-switch. Nobody sees it, nobody answers it, and the call blocks on the stream's own thread — the capture-loss rebuild, or the restore worker — while the rebuild budget burns. The takeover then lands after the session it was for already ended. With the flag it fails immediately ("interactive authentication required"), which is what both callers are already written for: the packaged pkexec helper (allow_any, no agent needed) takes it from there. A sentinel with no baseline is not a request. `session_select_requested` read "no baseline recorded" as "the sentinel appeared during the session" — but `~/.config/steamos-session-select` is a permanent file, so every box whose user has ever switched sessions has one. The baseline was recorded only after a SUCCESSFUL launch, leaving a real window: takeover succeeds, launch fails, the client retries inside the 5s restore debounce (which the retry cancels), and the honor gate fires on a months-old write — pushing the box to the desktop the user never asked for, plus a 120s grace refusing to relaunch game mode. Now the baseline is taken at takeover too (setting STOPPED_DM is what arms the gate), and "never baselined" reads as no request. `SESSION_SELECT_BASELINE` carries both states explicitly, and the decision is a pure `sentinel_advanced` with a unit test for all six cases. Checked on Linux: cargo check --all-targets, clippy -D warnings, 77 tests, rustfmt.	2026-07-27 19:04:20 +02:00
enricobuehlerandClaude Fable 5	ba89b9fcd0	feat(tools): display-disturb learns the bench moves the field sessions needed ... Three upgrades from the on-glass rounds on .173/.221: - `ddc-open` timing: the handle-ACQUISITION cost per monitor is reported even when it yields no physical handles — the poller's first contact with a virtual display, exactly what the DDC-fail-fast driver work changes; the old code silently skipped handle-less monitors, which on a streaming host in exclusive topology is every monitor there is. - Monitors are labeled by GDI device name (\\.\DISPLAYn) so a virtual display and a panel are tellable apart in the correlation log. - `extend` mode: one SDC_TOPOLOGY_EXTEND poke — re-activates every attachable display, i.e. the exact 'non-managed display re-activated' event the exclusive watchdog evicts.

Field A/B (reporter, Legion 5 Pro hybrid, 2026-07-27): the ~2 s capture-stall metronome IS the exclusive isolate's own doing — deactivating the laptop panel leaves a dark-but-connected eDP head whose driver-level servicing disturbs the capture path (~1.7-2.8 s period); `topology: primary` (panel stays active) stopped it outright (16.3 stalls/min → 0). Our own .221 logged the identical signature the day before. The detector then steered AWAY from the cause: connected_inactive filtered to EXTERNAL physicals only, so the one display that mattered — on a hybrid laptop, the default config — reported as `none`. - TargetInventory: new `internal_panel` class bit (eDP/LVDS/embedded). - connected_inactive_externals → connected_inactive_physicals: internal panels join the suspect list (virtual/indirect stay excluded); a nameless panel renders as "laptop panel". - The below-OS METRONOMIC warn names the dark-panel case and its actual cures (`topology: primary`, `pnp_disable_monitors`) — the old text's "unplug it" prescriptions are impossible for an internal panel. - ddc_power_off: a zero-ack sweep now says at INFO that the axis did nothing (internal panels have no DDC/CI) instead of silently no-op'ing.

enricobuehlerandClaude Fable 5	ab58fd2f0e	feat(vdisplay/driver): DDC/CI against the virtual monitor fails fast ... In exclusive topology the virtual display is the ONLY monitor on the desktop, so monitor-control software (the Twinkle Tray / PowerToys PowerDisplay / Monitorian class) aims its entire DDC traffic — brightness polls, capabilities-string requests — at OUR monitor. There is no bus and no sink; the only wrong answer is a slow one (a timeout-shaped failure occupies win32k's physical-monitor path, serialized per monitor, for its full duration). Register EvtIddCxMonitorI2CTransmit/Receive and answer every probe with an immediate STATUS_NOT_SUPPORTED, making the virtual monitor the cheapest thing on the "bus" to poll.

The exclusive-topology reassert's forced re-commit transiently bounces the virtual display's mode; the descriptor poller can sample that EVICTION state and recreate the ring at a mode the recovery chain is about to undo (field log 2026-07-27 10:30:44Z: hdr=true → false → recreate → recovery restores true → second recreate). New pf-win-display::topology_churn latch (deadline semantics — self-expiring, so a lost release can never wedge descriptor- following off): the watchdog holds it for interval+3s each fighting round and releases on "stable again"; poll_display_hdr consumes samples but acts on nothing while held — which also keeps the negotiated-depth pin-back from issuing a CCD write mid-eviction, where it would fight the reassert itself.

The stall-immunity bench needs both stall classes on demand, without a standby TV or a monitor-tool storm: `ddc` replays the Twinkle-Tray/PowerDisplay-class DDC/CI traffic (VCP reads, optional capabilities-string requests) through the win32k I2C path; `modeset` re-commits the current mode with CDS_RESET — the Level-Two modeset entry that idles the whole adapter with nothing Win32-visible changing. Every op prints an epoch-stamped took_ms line so host.log stall reports correlate line-for-line, and the op duration itself measures the driver's service time per disturbance.

enricobuehlerandClaude Fable 5	19d6f79d2d	feat(vdisplay/driver): the frame pump survives MMCSS refusal and outranks GPU contention ... Two stall-immunity hardenings for the swap-chain drain thread (branch-2 of the disturbance-immunity program — failures in OUR delivery leg, as opposed to adapter-wide display servicing, which no priority survives): - MMCSS registration fails under the restricted WUDFHost token on some boxes; the drain thread then ran UNPRIORITIZED — the whole display's frame pump at normal priority, starvable by DDC/HPD-servicing DPC pressure into multi-hundred-ms delivery holes. Fall back to TIME_CRITICAL. - IddCxSetRealtimeGPUPriority (IddCx 1.9) raises the processing device above every regular application's GPU priority. Slot availability comes from raising the exported IddMinimumVersionRequired 4 → 10, which was overdue independently: the drain loop already calls ReleaseAndAcquireBuffer2 (1.10) unconditionally, so binding a pre-1.10 framework would dispatch past the populated IddFunctions table — with 10 an old framework fails the bind cleanly instead. The product floor is already Win11 22H2 (installer MinVersion=10.0.22621, whose framework is 1.10), so no supported system changes behavior.

enricobuehlerandClaude Fable 5	94f0207cbd	feat(windows/client): logs persist — %LOCALAPPDATA%\punktfunk\logs\client.log ... The shell is a windows_subsystem binary and spawns punktfunk-session with CREATE_NO_WINDOW + inherited stderr: a normal GUI/MSIX launch has no console, so every log line — the shell's and the session's whole receive/decode/present forensic trail — evaporated exactly when a user hit something worth reporting. The 2026-07 PyroWave latency-sawtooth report had to be triaged from host logs alone; the deciding evidence (clock re-sync vs backlog-flush lines) lives client-side. - New logfile module: %LOCALAPPDATA%\punktfunk\logs\client.log, the host's rotation convention (10 MB cap -> .old at next start, one generation), best-effort (no dir -> plain stderr, never a startup failure). - The tracing subscriber tees to stderr AND the file (ANSI off — the file is what users send); startup logs the path. - The spawned session's stderr is piped through the same tee, line-buffered — dev-terminal runs keep their interleaved output, GUI runs finally keep anything at all. - The --console path and the punktfunk-console.exe MSIX shim forward the same way (a couch launch has no console either).

enricobuehlerandClaude Fable 5	2c69cbdab9	docs(host/stats): say what the stats actually measure — three field-triage traps ... Three lines that each sent the 2026-07 PyroWave field triage down a wrong path, made honest: - The 'client accepts streamed AUs … will stream per-slice' log fires before the encoder exists and regardless of backend support (only Linux direct-NVENC implements chunked polling) — it now states the client capability only. - StatsSample::mbps was documented as 'transmit goodput'; it is attempted sealed wire bytes at seal time — AU bytes + shard framing + FEC parity (+ PyroWave window padding), not reduced by socket send drops. - The per-stage split's 'encode' stage is the poll() duration, which is ~0 by construction for synchronous backends (PyroWave encodes inside submit → its time shows as 'submit') — documented at the split's definition so 'encode 0.00' stops reading as an instrumentation hole.

enricobuehlerandClaude Fable 5	d8d8c6c43d	fix(core/abr): the capacity probe's own overload no longer reads as session congestion ... The startup speed-test probe deliberately overloads the link (2 Gb/s for 800 ms) to measure capacity. The report tick is suppressed while it runs and the window anchors are rebased when it ends — but two residues leak past the rebase: probe frames still pending in the reassembler age out as frames_dropped for another ~120 ms (the loss-window fuse), and the burst can latch flush_in_window (a jump-to-live it caused itself). Either one reads as a SEVERE window: the controller backs off ×0.7 and — worse — slow start ends at the first congestion signal, permanently. That is precisely the 2026-07 field report's Automatic session: 20→14 Mb/s exactly one report tick after the probe, then a purely additive +6 %/4.5 s crawl that took the whole 4.5-minute match to reach 308 Mb/s on a link the probe had just measured at ~1.2 Gb/s. Slow start (doubling per clean window to the probed ceiling, 'seconds instead of minutes') never got to run. The first post-probe report window is now discarded outright: no LossReport (probe residue would also spike the host's adaptive FEC), the standing-latency detector closes it as not-loss-free (its clean-run just resets), and the ABR is fed nothing.

enricobuehlerandClaude Fable 5	b8b8ac336c	feat(core/client): all-intra streams drain the frame channel to the newest AU ... The pre-decode FrameChannel is strictly FIFO because H.26x reference chains forbid mid-stream drops — falling behind is only recoverable via the coarse jump-to-live thresholds (depth ≥6 sustained, or 400 ms behind the capture clock) at the cost of a keyframe round-trip. PyroWave has no reference chains: every AU decodes independently, so a slow consumer can skip straight to the newest queued AU with zero recovery cost. The pump now flags the channel all-intra for PyroWave sessions and pop() drains to the newest, which caps any standing pre-decode queue at ~1 frame structurally — the 2026-07 field report's 780M client could otherwise ratchet a real multi-frame backlog (and with it the OSD latency) between those coarse thresholds. Skips are counted separately from losses (they were delivered, just superseded) and surfaced at debug on the report tick — the OSD 'lost' line keeps meaning wire loss.

enricobuehlerandClaude Fable 5	6d1baa0add	fix(pf-encode/pyrowave): the bitrate pin holds on the WIRE, not the raw bitstream ... A datagram-aligned PyroWave session inflates the codec bitstream ×1.2–1.3 on its way to the wire — greedy packing of few-hundred-byte atomic block packets into 1408 B windows zero-pads most window tails, plus the 4-byte prefixes and FRAG chains. The 2026-07 field report's 1440p60 10-bit "Automatic" pin of 407 Mb/s put a measured 550 Mb/s on a 1 GbE link; nothing enforced the pin past the rate controller. New shared WireBudget (pyrowave_wire.rs, both backends): tracks the real per-frame AU/bitstream ratio as a ×1024 fixed-point EMA (prior ×1.25, weight 1/8, clamped ×1.0–×2.0) and deflates the budget handed to pyrowave's rate control by it, so the windowed AU lands on the configured rate. Sealed-datagram framing (+4.5%) and FEC parity stay uncompensated — H.26x sessions carry those on top of the configured bitrate too, and the pin must mean the same thing for every codec. Dense (non-chunked) sessions are untouched. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-27 12:51:11 +02:00
enricobuehlerandClaude Fable 5	53640b8754	fix(core/clock): re-sync survives loaded links — floor baseline, spaced rounds, bounded staleness ... The mid-stream clock re-sync starved on high-bitrate LAN sessions (2026-07 PyroWave-sawtooth field report, RX 9070 XT -> 780M @ 550 Mb/s): every batch was judged against the CONNECT-TIME RTT, measured before the video data plane existed, with a 2 ms floor — mid-stream control RTTs on a loaded GbE link sit above that almost permanently, so batches were rejected for minutes while the wall clocks drifted apart and the OSD e2e figure ramped 19->150 ms before snapping back on a lucky batch. Three changes: - Rounds are spaced 7 ms apart (stamped at send time, so the spacing never lands in the RTT). An 8-round batch used to complete inside ONE ~6 ms video burst — all rounds sampled the same congestion state; spacing walks them across the frame cycle so the min-RTT round finds a quiet gap. - ResyncGuard replaces the static baseline: the guard band follows the best RTT the session has evidenced (connect RTT, then min over every completed batch — rejected ones included). - Rejection streaks are bounded: after 3 consecutive rejections the best (min-RTT) batch of the streak is applied anyway. Its queueing bias is at most ~half its RTT; unbounded wall-clock drift costs more per minute. Rejections now log at warn with the streak and floor — the starvation signature is grep-able in exactly the logs users send.

enricobuehler	94b7a834cb	fix(installer/windows): GameStream is opt-in, not on by default ... A user found this in their log and had never been offered a choice: WARN GameStream/Moonlight compat ENABLED (--gamestream): its pairing runs over plain HTTP and its legacy control encryption can reuse GCM nonces (security-review #5/#9) — an on-path LAN attacker could MITM pairing or recover input. Enable only on a TRUSTED network. They were right. The `gamestream` task carried no `Flags: unchecked`, so it was pre-ticked; and since a silent install takes the wizard's own task defaults (1839d756), a winget install turned it on with no checkbox ever shown. The host warns that this plane is a security downgrade on every single start, so having the installer enable it by default cannot be squared with our own advice — least of all on the path where nobody sees a wizard. Now unchecked, matching `allowpublicfw`, the other task with a security consequence. A default install therefore lands `PUNKTFUNK_HOST_CMD=serve`, the native-only host; Punktfunk's own clients are unaffected, since the native punktfunk/1 plane is always on. Unattended opt-in is `/MERGETASKS=gamestream`. Scope, deliberately: this changes FRESH installs only. `GamestreamParam` already omits the flag entirely unless `FreshHostInstall`, so no existing host has its choice touched by an upgrade, and anyone relying on Moonlight today keeps it. `DEFAULT_HOST_CMD` (the service's fallback when host.env carries no PUNKTFUNK_HOST_CMD line at all) is deliberately NOT flipped here: the installer always writes the line explicitly, so it does not affect a normal install, and inverting it would silently disable Moonlight for anyone whose host.env lost that line — a runtime regression that belongs in its own change, if at all. Docs corrected everywhere they stated the old default, since three of them now told users the opposite of what ships: the winget Agreement shown BEFORE install (it said "enabled by default" and gave the opt-OUT override), the Windows packaging README, and host.env.example. The `--override` example in the installer manifest is inverted with it (`/MERGETASKS=gamestream` to add, `!` to remove). Verified: [Tasks] + [Code] compile with ISCC 6.7.1 on the windows-amd64 runner (all optional features defined), and the winget catalogue rebuilds and passes 29/29 with the edited manifests.	2026-07-27 12:26:47 +02:00
