enricobuehler	7b99b41ede	docs(design): trim shipped plans, consolidate cluster, add index ... Much of design/ described work that has since shipped. Trim each doc to its durable rationale + still-open items (the code is the source of truth for shipped detail; git history holds the full originals). - Shipped plans -> status stubs: stats-capture, gamestream-host-plan, apple-stage2-presenter, windows-service. - Trimmed completed-out / open-kept: implementation-plan, hdr-pipeline, host-latency, gpu-contention (fixed stale status table), game-library, linux-setup (fixed m0->spike + stale zero-copy claim), session-aware-host-followups, windows-client-bootstrap, windows-dualsense-{scoping,game-detection}, windows-virtual-display, security-review (per-finding status table; #12 still open), apollo-comparison (shipped backlog collapsed to one-liners). - Windows-host cluster consolidated: windows-host.md -> redirect into windows-host-rewrite.md (whose stale scorecard is corrected -- goal1 is merged, M4 done); windows-secure-desktop.md archived (now a fallback behind IDD-push primary). - Kept evergreen: ci.md, gamescope-multiuser.md, windows-build-and-packaging.md. - New design/README.md: per-doc status table + consolidated open-items roll-up so nothing is tracked in only one buried doc. - Repoint 5 code comments to the archived secure-desktop doc path.

enricobuehler	5bf787eb2b	feat(host): web-console performance capture — record stream stats, graph them ... Arm streaming-perf-stats capture from the web console, play, stop, and review the run as graphs; finished captures are saved to disk as browsable/exportable recordings. Covers both the native punktfunk/1 path and GameStream. - stats_recorder.rs: one shared Arc<StatsRecorder> ring (created in gamestream::serve, shared with the mgmt API + both streaming loops, mirroring NativePairing). The hot-path gate is a runtime AtomicBool that replaces the startup-only PUNKTFUNK_PERF for *recording* (PERF stdout logging unchanged); bounded ring (~3 h); atomic temp+rename writes to ~/.config/punktfunk/captures/*.json; path-traversal-safe ids; poison-resilient locks. - native (punktfunk1.rs) + GameStream (stream.rs) emit a StatsSample at their existing ~2 s / ~1 s aggregation boundary — per-stage latency p50/p99, fps new/repeat, goodput, loss/FEC deltas — with no new per-frame work beyond the cheap atomic check. FrameMsg.was_measured keeps pre-arm in-flight frames out of the first window's percentiles (without zeroing the Windows-relay path's fps/encode). - mgmt.rs: 7 bearer-only /api/v1/stats/* endpoints (capture start/stop/status/live; recordings list/get/delete); api/openapi.json regenerated, in sync. - web: new "Performance" page (recharts, rendered SSR-safe) — capture control, live graphs while armed, recordings table (view / download-JSON / delete), and a detail view with the latency stacked-area bottleneck breakdown (p50/p99 toggle) + throughput + health. Charts adapt to either path's stage set. Design: design/stats-capture-plan.md. Built and adversarially reviewed via a multi-agent workflow; workspace build/clippy(-D warnings)/fmt/tests green, OpenAPI no-drift. Not yet on-glass validated against a live session.

enricobuehler	f6490f4c28	fix: complete the docs/→design/ and openapi→api/ rename references ... The file moves (docs/ → design/, docs/api/openapi.json → api/openapi.json) landed in d01a8fd, but the matching reference updates did not — so mgmt.rs's drift-test `include_str!("../../../docs/api/openapi.json")` pointed at a path that no longer exists and the host failed to build. This restores it and updates every reference: - mgmt.rs include_str! → ../../../api/openapi.json (fixes the build) - web/orval.config.ts codegen target, web/Dockerfile, .dockerignore - deb/rpm/Arch packaging install paths - CLAUDE.md, the .gitea CI workflows, code doc-comments, design-doc cross-links docs-site route URLs (/docs/...) untouched.

enricobuehler	7aa787a789	docs(host): prove the last 3 files + crate-root deny (unsafe-proof program 4/N, final) ... Completes the unsafe-proof program now that the parallel WIP has landed: - idd_push.rs (25 sites), nvenc.rs (7), punktfunk1.rs (21): a SAFETY proof on every unsafe block — D3D11/DXGI COM (same-device textures, immediate-context single-thread, keyed-mutex-held convert), the NVENC SDK table (versioned POD, register/map/lock-bitstream pairing), cross-process shm reads (atomic magic/generation handshake), and the C-ABI harness (each call cross-checked against its abi.rs `# Safety` doc). No SUSPECT (UB) blocks. - capture.rs / encode.rs: the parent-module deny is restored (their WIP children are now proven), and main.rs gains a crate-root #![deny(clippy::undocumented_unsafe_blocks)] — the permanent catch-all gate so no future unsafe block anywhere in the crate can land without a proof. - Fixed 4 blocks the agents missed: unsafe blocks nested inside `assert_eq!(...)` macro args (the comment-above-statement didn't associate) — hoisted to a `let`. - rustfmt-canonicalized the Windows files (the agents' SAFETY comments + some pre-existing 1.9.0 drift) so `cargo fmt --all --check` is clean. Verified: cargo clippy -p punktfunk-host --all-targets -- -D warnings AND cargo fmt -p punktfunk-host --check both green with the crate-root deny active. Windows cfg(windows) re-verified on the box next. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-26 09:57:00 +00:00
enricobuehler	c87ca577a3	feat(windows-host): launch the chosen library title into the interactive session ... Make the no-op Windows `set_launch_command` real. New `windows/interactive.rs` `spawn_in_active_session` (WTSGetActiveConsoleSessionId → WTSQueryUserToken → CreateProcessAsUserW(winsta0\default) under the LOGGED-IN USER token, factored from the wgc_relay primitive) + `library::launch_title` resolving a store-qualified id to a concrete process via `windows_launch_for` (steam_appid → Steam.exe/explorer.exe steam:// URI; command → cmd.exe /c). Threaded as `SessionContext.launch` into both native data-plane paths (`virtual_stream`, `virtual_stream_relay`) and fired after capture is live so the title renders onto the captured desktop and grabs foreground. Security invariant intact: the client sends only the store-qualified id; the host resolves the recipe from its own library and the URI/flags are handed to a concrete EXE as plain args (never cmd /c of a client string). Linux unchanged (gamescope nesting via the handshake PUNKTFUNK_GAMESCOPE_APP path). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-26 06:51:10 +00:00
enricobuehler	38c68c33e5	refactor(windows-host): confine platform code under windows/ + linux/ folders (Goal-1 stage 6) ... Move 36 platform-specific files into per-module `windows/` and `linux/` subfolders (and the shared HID codecs into `inject/proto/`): capture/{windows,linux}/ encode/{windows,linux}/ inject/{windows,linux,proto}/ audio/{windows,linux}/ vdisplay/{windows,linux}/ src/windows/ (service, wgc_helper, win_adapter, win_display) src/linux/ (dmabuf_fence, drm_sync, zerocopy/) Done with `#[path]`, NOT a module rename: every file moves into its folder while the `crate::*::*` module names stay FLAT, so all caller paths and every internal `super::`/`crate::` reference are unchanged — only the parent `mod` decls gained `#[path = "..."]`. This is the codebase's existing pattern (inject's gamepad_windows) and makes the move byte-identical in behaviour with ZERO reference churn, far lower risk than collapsing to a single `crate::capture::windows::` namespace (that deeper rename is an optional follow-on; this delivers the cfg-sprawl folder confinement the stage is about). Done LAST, after the semantic stages, so the path churn didn't fight them. Verified: Linux cargo check + clippy (-D warnings) clean; my mod-decl changes fmt-clean (the 3 remaining fmt diffs are pre-existing local-rustfmt-version skew that moved with their files); all 36 `#[path]` targets exist; no internal `#[path]`/`include!`/file-child-mod in any moved file (the inline `mod X {` blocks are self-contained). Box build to follow. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-25 18:53:45 +00:00
enricobuehler	0a63154293	feat(windows-host): SessionPlan — resolve capture/topology/encoder once per session (Goal-1 stage 3) ... New src/session_plan.rs: a Copy `SessionPlan { capture, topology, encoder, bit_depth, hdr }` resolved ONCE from HostConfig (+ the negotiated bit_depth) at the top of `virtual_stream`, logged, and threaded through build_pipeline_with_retry/build_pipeline. The three scattered Windows dispatch points now read this one typed artifact instead of re-deriving from config (plan §2.4, the "capture and encode disagree on the backend" hazard): * capture: capture::capture_virtual_output takes a CaptureBackend IN (was re-reading config().idd_push / capture_backend / no_wgc internally). CaptureBackend::resolve() is the single resolver, shared with the GameStream + spike call sites. * topology: virtual_stream reads plan.topology; should_use_helper is deleted (its body is session_plan::resolve_topology, verbatim). The IDD-push reconnect-preempt guard reads plan.capture too. * encoder: recorded as EncoderBackend from encode::windows_resolved_backend (config-backed + GPU-vendor cached since stage 2 -> already a single source). Threading encoder/input_format into the encoder+capturer opens (which removes the capture->windows_resolved_backend() back-reference recomputed in dxgi.rs) is stage 5. Behavior-preserving by construction: each resolved decision is provably equivalent to the pre-stage-3 reads (same config() + the same cached running_as_system()/GPU-vendor probes), so old==new. SessionPlan is platform-neutral so it threads the shared virtual_stream/build_pipeline signatures; on Linux it resolves to the single portal/single-process path. Also fixes a pre-existing mod-ordering fmt drift in main.rs (mod config; / mod capture;). Verified: Linux cargo check + clippy (-D warnings) + fmt clean on the touched files. Box build (Windows compile) + on-glass (NVENC + IDD-push + mode switch) pending on the RTX box. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-25 17:47:48 +00:00
enricobuehler	a3eefc2374	feat(windows-host): HostConfig foundation + staged Goal-1 roadmap (Goal-1 stage 1) ... config.rs: typed HostConfig parsed ONCE from env (idd_push/encoder_pref/no_helper/force_helper), replacing per-call env::var re-reads (PUNKTFUNK_ENCODER was re-read on EVERY windows_resolved_backend() call; PUNKTFUNK_IDD_PUSH is read 8x across the host — the recompute that lets capture + encode disagree on the backend, plan §2.4). Migrated the two highest-churn dispatch reads onto it (encode::windows_resolved_backend, punktfunk1::should_use_helper). Behavior-identical: the env is constant for the process lifetime (the service loads host.env before launch), so a lazily-parsed global == parsed-once-at-startup. docs/windows-host-goal1-plan.md: the ORDERED, independently-shippable execution plan for Goal-1 (the plan's biggest unstarted goal — a from-scratch layered host architecture). Six behavior-preserving, box-verified stages (HostConfig -> SessionPlan -> SessionContext/SessionFactory -> seam-trait tightenings -> src/windows tree), because the host is live-validated and a monolithic rewrite would strand it broken. Stage 1 done here; stages 3-5 rewire the deployed path and require on-glass re-test. Verified: Linux + box (--features nvenc) cargo check clean.

enricobuehler	e60cda3939	refactor(windows-host): move CCD/HDR display helpers to a neutral module — F1 complete (audit §9) ... Moved the remaining 6 SudoVDA reach-in helpers + SavedConfig (resolve_gdi_name, set_advanced_color, advanced_color_enabled, set_active_mode, isolate/restore_displays_ccd) verbatim from vdisplay::sudovda into a backend-neutral crate::win_display module (the plan's windows/display_ccd.rs). The capturers (idd_push/dxgi/wgc), pf_vdisplay, and punktfunk1 now depend on these as PEERS via crate::win_display instead of reaching into the SudoVDA backend. With win_adapter (F1 pt1), all 7 reach-in helpers are now neutral — the circular reach-in is broken, so SudoVDA can eventually be deleted (Goal 2) without losing the display utilities. sudovda re-exports the ones it still uses internally; its now-unused CCD/GDI imports were removed. Verified: host clippy (nvenc) clean on the RTX box; Linux check clean (the new modules are #[cfg(windows)]).

enricobuehler	d638a93e04	refactor(windows-host): move resolve_render_adapter_luid to a neutral module (audit §9 / F1 pt 1) ... The discrete-render-GPU LUID picker was display-utility living in the SudoVDA backend; moved it verbatim to a backend-neutral crate::win_adapter module (the plan's windows/adapter.rs). The IDD-push capturer + pf-vdisplay backend now depend on it as a PEER instead of reaching into vdisplay::sudovda — the first step in breaking the circular reach-in so SudoVDA can eventually be dropped (Goal 2). sudovda re-exports it for its own callers. Remaining F1 increments: the CCD/HDR helpers (resolve_gdi_name, set_advanced_color, advanced_color_enabled, set_active_mode, isolate/restore_displays_ccd) → a neutral win_display module. Verified: host clippy (nvenc) clean on the RTX box. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-25 13:33:23 +00:00
enricobuehler	b0c82333d2	feat(gamepad): pure-user-mode Windows DualShock 4 + Xbox 360 (drop ViGEm) + installer + multi-pad ... Windows virtual gamepads now have zero external dependencies - ViGEmBus is removed. - DualShock 4: Windows UMDF backend (inject/dualshock4_windows.rs + dualshock4_proto.rs), reusing the DualSense SwDeviceCreate game-detection identity fix. The one UMDF driver serves the DS5 or DS4 identity/descriptor/features/strings per a device_type byte the host stamps into shared memory. Driver also gains IOCTL_HID_GET_STRING and a 41-byte calibration feature. - Xbox 360: a new UMDF2 XUSB companion driver (packaging/windows/xusb-driver/) that registers GUID_DEVINTERFACE_XUSB and answers the buffered XInput IOCTLs from a shared section, so classic XInputGetState/SetState work with no kernel bus driver. inject/gamepad_windows.rs is rewritten to drive it and the vigem-client dependency is removed. Xbox One folds to the 360 XInput path. - Installer: vendor + pnputil-install the three UMDF drivers (packaging/windows/gamepad-drivers/ + install-gamepad-drivers.ps1, wired into pack-host-installer.ps1 + punktfunk-host.iss). - Multi-pad: the host stamps each pad index into the device Location (pszDeviceLocation); the driver reads it via WdfDeviceAllocAndQueryProperty to map its own *-shm-<index>, with UmdfHostProcessSharing=ProcessSharingDisabled giving each pad its own host (per-pad statics). Validated live on the Windows host: Cyberpunk native DualSense detection, DS4 identity + descriptor, XInputGetState + rumble round-trip, two pads -> two distinct XInput slots, and a full installer build.

enricobuehler	6db3525e29	fix(gamepad): working per-session SwDeviceCreate for the Windows DualSense ... create_swdevice now succeeds. The two requirements (each E_INVALIDARG otherwise): the enumerator name must have no underscore (use "punktfunk"), and the completion callback is mandatory (the docs mark pCallback [in], not optional -- NULL is rejected). Back on the typed windows-rs SwDeviceCreate (a raw-FFI diagnosis confirmed it's the OS, not the binding), parameterized by pad index (instance pf_pad_<index>), waiting on the callback. Per-session device: created on connect, SwDeviceClose'd on drop -- no leftovers, no phantom. Live-verified on the RTX box: device materializes, the UMDF driver binds, SDL3 identifies it as a PS5 ("DualSense Wireless Controller"), input flows; removed on disconnect. The dualsense-windows-test CLI now cycles input + prints any 0x02 feedback for diagnosis. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-22 10:34:58 +00:00
enricobuehler	fde438a1ed	feat(gamepad): SwDeviceCreate per-session devnode (best-effort) + windows self-test ... DualSenseWindowsManager now SwDeviceCreate's the pf_dualsense devnode per session (SwDeviceClose on drop), matching the Linux UHID pad's lifecycle. It's best-effort: SwDeviceCreate currently hits an unresolved E_INVALIDARG when a completion callback is passed (an underscore in the enumerator name was a second cause, fixed by using "punktfunk"), so on failure the host keeps the section + data plane and falls back to an out-of-band devnode (installer/devgen) — see docs/windows-dualsense-scoping.md. Add a `dualsense-windows-test` host CLI that drives the manager (create devnode + push a frame + hold), used to validate the path. Live on the RTX box: the manager creates the section + pushes report 0x01 and a devnode serves it to a HID read (b1=0xC0, b8=0x28) — the host-side data plane works end to end. cargo check + clippy -D warnings clean on x86_64-pc-windows-msvc.

enricobuehler	4a73102d48	feat(gamepad): virtual DualSense on the Windows host (UMDF shm channel) ... Wire the Windows UMDF DualSense driver into the host as a real pad backend, so a client that requests a DualSense gets a genuine one on a Windows host (instead of folding to Xbox 360). - Extract the transport-independent DualSense contract (DsState + from_gamepad, serialize_state, parse_ds_output, DUALSENSE_RDESC, feature blobs, DS_* consts) out of the Linux-only UHID backend into inject/dualsense_proto.rs, shared by both platforms; dualsense.rs is now just the /dev/uhid plumbing. - Add inject/dualsense_windows.rs: DualSenseWindowsManager mirroring the Linux DualSenseManager (same new/handle/apply_rich/pump/heartbeat surface) over a DsWinPad that creates the Global\pfds-shm-<idx> section (CreateFileMappingW + SDDL D:(A;;GA;;;WD) so WUDFHost can open it), writes serialize_state -> input slot, polls output_seq -> parse_ds_output -> rumble/hidout callbacks. - Un-gate the seam: PadBackend::DualSenseWindows arm; pick_gamepad gains a windows flag (DualSense honored on linux||windows; DS4/Xbox One stay Linux-only). Verified: Linux cargo test gamepad_resolution_precedence + clippy clean; Windows cargo check + clippy -D warnings clean (on the RTX box). Device lifecycle still uses an out-of-band devnode (devgen/installer); SwDeviceCreate per session is next. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-21 20:36:53 +00:00
enricobuehler	54b75c9be4	feat(host): GameStream/Moonlight compat is now opt-in (--gamestream) — secure native-only by default ... Follows the security audit (#5/#9): the GameStream-compat plane carries inherent on-path weaknesses that can't be fixed on the wire without breaking stock Moonlight — its pairing runs over plain HTTP (#9, MITM-able during the pairing window) and its legacy control encryption can reuse GCM nonces (#5, a passive eavesdropper can recover/forge input). The native punktfunk/1 plane (SPAKE2 PIN pairing + per-direction AEAD nonces) has neither. So flip the default to secure-by-default: - `serve` → native punktfunk/1 plane + management API ONLY (no GameStream surface). - `serve --gamestream` → ALSO the GameStream/Moonlight-compat planes (nvhttp pairing, RTSP, ENet control, _nvstream mDNS). Opt-in, logged with a trusted-LAN caveat. `--moonlight` is an alias. - The native plane is now ALWAYS on in `serve` (`--native` is a kept-for-compat no-op); the unified GameStream+native host is `serve --gamestream`. `gamestream::serve` gates the GameStream spawns (nvhttp/rtsp/control/mdns) on the flag; the native plane + mgmt + native-pairing handle always run. To avoid silently regressing validated Moonlight deployments, the explicit deployment configs PRESERVE Moonlight via `--gamestream` (each documents dropping it for a secure native-only host): the Linux systemd unit, the Steam Deck installer, and the Windows service default (DEFAULT_HOST_CMD). The bare `serve` default (new/manual use) is secure. Docs swept to match (host-cli, moonlight, quickstart, install, packaging READMEs, CLAUDE.md, README, …): Moonlight setup now instructs `--gamestream`; native/console refs use bare `serve`. OpenAPI regenerated (a stale "run `serve --native`" string). fmt + clippy clean; 94 host tests green. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-21 10:19:40 +00:00
enricobuehler	3526517eb1	feat: HDR Step-0 colour-metadata transport + security-audit hardening ... Two strands, entangled in punktfunk1.rs, committed together (one builds-green tree). HDR pipeline Step 0 — glass-to-glass colour-metadata transport (docs/hdr-pipeline-plan.md): - Protocol/ABI: ColorInfo on the Welcome + a 0xCE HdrMeta datagram carry the source colour space + HDR10 static mastering metadata (quic.rs, abi.rs connect_ex5 fixing caps=0). - New platform-independent, unit-tested HDR static-metadata helpers (hdr.rs): chromaticities (1/50000), mastering luminance (0.0001 cd/m2), MaxCLL/MaxFALL in HDR10/ST.2086 units. - Capture/encode hooks (capture.rs, encode.rs set_hdr_meta) + Linux client / probe plumbing. Security-audit hardening — top 3 from docs/security-review.md, each adversarially verified: - #1 [HIGH] Secret file permissions. The host key.pem/cert.pem and both trust stores are now written owner-only: 0600 + dir 0700 on Unix (mirrors mgmt_token), best-effort SYSTEM/Administrators/OWNER-only icacls DACL on Windows (%ProgramData% is Users-readable). Closes a local key-disclosure -> host-impersonation gap. New gamestream::{create_private_dir, write_secret_file} + a 0600 regression test. - #2 [HIGH] Native SPAKE2 PIN is single-use. The PIN is consumed the moment the host sends its key-confirmation (which lets the client test its one guess), before reading the proof, so any completed attempt -- right OR wrong -- disarms the window. A wrong PIN isn't observable host-side (the client aborts before sending its proof), so consuming on first attempt is what delivers the documented "one online guess" instead of an unbounded brute-force of the static 4-digit PIN. Test verifies single-use. - #3 [MEDIUM] RTSP packetSize is bounded ([64,2048] in stream_config) and VideoPacketizer::new uses saturating .max(1), killing a PRE-AUTH div-by-zero/underflow panic of the video thread. Tests for {0,15,16,17} + out-of-range rejection. fmt + clippy -D warnings clean; full workspace test suite green (93 host tests).

enricobuehler	aef552f04a	feat(host/windows): HDR scRGB→P010 in a shader — NVENC native P010, off the SM ... On the Windows WGC HDR path the FP16 scRGB capture was fed to NVENC as R10G10B10A2 (BT.2020 PQ), and NVENC did the RGB→YUV CSC internally on the contended SM — adding to the encode_ms wall under a GPU-saturating game. (NVIDIA's D3D11 VideoProcessor can't do RGB→P010 for HDR; that path renders green, confirmed live — so the convert must be ours.) New `HdrP010Converter` fuses the tone-map with the BT.2020 RGB→YUV matrix and emits P010 (10-bit limited range) directly: a luma pass → an R16_UNORM plane RTV (full-res) and a chroma pass → an R16G16_UNORM plane RTV (half-res, 2x2 box average) of a DXGI_FORMAT_P010 texture. NVENC then takes native P010 and skips its SM-side convert. Gated behind PUNKTFUNK_HDR_SHADER_P010 (default OFF → the existing R10→NVENC path is byte-for-byte unchanged). Colour validated by a new `hdr-p010-selftest` subcommand: a synthetic scRGB pattern → P010 → readback, compared to a BT.2020 PQ 10-bit reference — max abs error Y=0.99 / Cb=0.82 / Cr=0.75 codes on an RTX 4090. Live-validated HDR colours correct (no green). Build + clippy (--features nvenc -D warnings) green on x86_64-pc-windows-msvc.

enricobuehler	1fc6f73784	perf(host/linux): NV12 GPU convert — feed NVENC native YUV, off the contended SM (Tier 2A) ... The Linux zero-copy tiled-GL path can now produce NV12 (BT.709 limited range) on the GPU and feed NVENC native YUV, deleting NVENC's internal RGB->YUV CSC — which runs on the SM/3D-compute engine a saturating game pins at 100% (the game-vs-encode contention headache). Windows already does this via the D3D11 video processor; this closes the Linux gap. See docs/host-latency-plan.md §2A. Gated behind PUNKTFUNK_NV12 (default OFF → the RGB/BGRx path is byte-for-byte unchanged; zero regression). Only the tiled EGL/GL path converts; the LINEAR/Vulkan-bridge (gamescope) path stays RGB. - zerocopy/egl.rs: Nv12Blit — BT.709 limited Y pass (R8, full-res) + UV pass (RG8, half-res, GL_LINEAR 2x2 average); both CUDA-registered; import_nv12. - zerocopy/cuda.rs: two-plane DeviceBuffer (Y W*H@1B + interleaved UV (W/2)*2 x H/2), paired Y+UV pool, copy_mapped_nv12 + copy_nv12_to_device, on the per-thread priority stream (dmabuf-recycle sync preserved). - encode/linux.rs: nvenc_input(Nv12)->NV12; submit_cuda copies two planes into NVENC's surface; VUI signalled BT.709 limited (colorspace/range/primaries/trc). - capture/linux.rs: gate (PUNKTFUNK_NV12 && tiled), report format Nv12. - main.rs + zerocopy/mod.rs: `nv12-selftest` subcommand. Validated on RTX 5070 Ti two ways: (1) nv12-selftest — synthetic RGBA->NV12 round-trip vs a BT.709 reference, max abs error Y=0.56/U=0.33/V=0.26 LSB; (2) live capture->NV12->NVENC->decode of animated red content matches the RGB path's colour (avg RGB 230,18,18 vs 231,18,20). build/clippy/fmt green.

enricobuehler	112a054c35	perf(host): latency hardening for the game-vs-encode GPU contention collapse ... Verified, prioritized analysis in docs/host-latency-plan.md (multi-agent investigation + adversarial verification). Lands the two low-risk tiers: Tier 2B — Linux scheduling hygiene: - boost_thread_priority now nices the capture/encode (-10) and send (-5) threads on Linux (setpriority, best-effort; no-op without CAP_SYS_NICE), and the wrong "gamescope caps the game" doc-comment is corrected. - CUDA context created with CU_CTX_SCHED_BLOCKING_SYNC (frees a core on the shared box instead of busy-spinning on completion). - Copies moved off the default stream onto a per-thread highest-priority CUDA stream (cuStreamCreateWithPriority, graceful NULL-stream fallback) with a per-stream sync that no longer blocks on the other worker thread's in-flight copies. Stream priority is measure-then-keep (NVIDIA Linux may ignore it); never regresses. Tier 3A — Windows session tuning (new session_tuning.rs, raw C-ABI FFI, no-op off Windows): once-per-process 1ms timer + DwmEnableMMCSS + HIGH priority class; per-thread MMCSS "Games" + keep-display-awake. Wired into both the native (boost_thread_priority) and GameStream (stream.rs) paths. We had zero session tuning before (Apollo streaming_will_start parity). Tier 2A (Linux NV12 convert) is specified but intentionally not landed: it is colour-correctness-critical and needs A/B validation on a GPU box with a display (green-screen risk). Builds + clippy + fmt green on Linux. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-18 23:05:57 +00:00
enricobuehler	9c8fa9340c	refactor: drop milestone names + consolidate clients; loss-recovery & rumble fixes ... Two bodies of work in one commit (the rename moved files the fixes also touched). Naming/structure cleanup (pre-launch): - Host modules m3.rs->punktfunk1.rs, m0.rs->spike.rs; CLI m3-host->punktfunk1-host, m0->spike; bare `punktfunk-host` now prints help. Types M3Options/M3Source-> Punktfunk1Options/Punktfunk1Source. - Clients consolidated out of crates/ into clients/: punktfunk-client-rs-> clients/probe (crate punktfunk-probe), client-linux->clients/linux, client-windows->clients/windows, punktfunk-android->clients/android/native (crate punktfunk-client-android; kept [lib] name=punktfunk_android so the JNI contract is unchanged). crates/ now holds only core + host. - Milestone codes M0-M4 purged from code/CLI/CLAUDE.md/README/docs/docs-site, kept only in docs/implementation-plan.md. docs/m2-plan.md-> docs/gamestream-host-plan.md. CI/gradle/flatpak paths updated. Client loss-recovery (video froze and never recovered after a brief drop): - Export punktfunk_connection_frames_dropped through the C ABI (the core already tracked it for the client keyframe-recovery loop; it was never reachable from the ABI clients). Regenerated punktfunk_core.h. - Apple (StreamPump + Stage2Pipeline) and Android (decode.rs) now poll frames_dropped and request a keyframe when it climbs -- the same loss-driven recovery Linux/Windows already had. Under infinite GOP the decoder silently conceals reference-missing frames, so the decode-error trigger rarely fires. Apple rumble robustness (worked then went spotty -- DualSense + Xbox): - Add CHHapticEngine stopped/reset handlers (rebuild on app background / audio interruption / server reset) and drop the permanent `broken` latch on a transient drive failure; latch only when the controller truly has no haptics. - Surface swallowed SDL set_rumble errors on Linux/Windows + diagnostic logging. Verified: cargo build/clippy/fmt --workspace, C-ABI harness, header drift. Not runnable on this box (verify in CI): Gitea workflows, gradle/Android, flatpak, Swift/decky.

enricobuehler	0ce2e37faf	refactor(host/windows): clean up DDA path + add a proper Windows service ... Final cleanup after the DDA-parity work, plus an end-user service to replace the PsExec/VBS/scheduled-task launch chain. Cleanup (behavior-preserving): - sudovda.rs: drop the dead legacy GDI isolate_displays/restore_displays (CCD is the sole isolation path), the always-empty Monitor.isolated field, and the vestigial reassert_isolation + PUNKTFUNK_ISOLATE_DISPLAYS knob; fix stale comments. - dxgi.rs: downgrade leftover debug warns/infos (DuplicateOutput1 retry, FALLBACKS, hook-hits, AcquireNextFrame idle timeout) to debug!; remove the PUNKTFUNK_NO_CURSOR per-frame test knob. Windows service (src/service.rs, `punktfunk-host service`): - SCM supervisor (windows-service crate) that duplicates its LocalSystem token, retargets it to the active console session, and CreateProcessAsUserW's the host there (Sunshine/Apollo model) — relaunching on exit and console session switch, inside a kill-on-close job object so a service crash never orphans the host. - install/uninstall/start/stop/status subcommands: one elevated `service install` registers an auto-start LocalSystem service + firewall rules + a default host.env. - Config moves to %ProgramData%\punktfunk\host.env; config_dir() now resolves to %ProgramData%\punktfunk on Windows (replacing the APPDATA=C:\Users\Public hack), with a PUNKTFUNK_CONFIG_DIR override. Logs land in %ProgramData%\punktfunk\logs\. - merged_env_block (shared with the WGC helper) now also carries RUST_LOG. - docs/windows-service.md + scripts/windows/host.env.example; windows-host.md updated.

enricobuehler	7cfeddc770	fix(host/windows): install the GPU-preference hook at process start (before any DXGI) ... The win32u hook only works if it patches before DXGI caches the hybrid preference. It was installed in DuplCapturer::open (first capture), but the SudoVDA render-adapter selection creates a DXGI factory during virtual-display setup — seconds earlier — so the preference was already cached and the hook had no effect (churn persisted; log showed "render adapter chosen" at :02, "hook installed" at :04). Call install_gpu_pref_hook() at the top of real_main(), before any command runs, so it beats the first DXGI factory. (open() still calls it too; Once makes the earliest call win.) Also fix the cosmetic function-cast-as-integer warning. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-16 12:39:50 +00:00
enricobuehler	9f50b3930d	feat(host/windows): two-process secure-desktop step 4 — spawn helper + relay AUs ... The SYSTEM host now sources the normal-desktop video from a user-session WGC helper instead of capturing in-process (WGC won't activate as SYSTEM). New `capture/wgc_relay.rs`: `HelperRelay::spawn` launches `m3-host wgc-helper` in the interactive user session via CreateProcessAsUserW (WTSQueryUserToken → DuplicateTokenEx(TokenPrimary) → lpDesktop="winsta0\\default", CREATE_NO_WINDOW) with three anonymous pipes — stdout (framed Annex-B AUs → parsed back to RelayAu), stdin (control: force-keyframe), stderr (helper logs → host tracing). The host holds the SudoVDA keepalive (sole isolation/topology owner); the helper captures by GDI name only. m3.rs: `virtual_stream` dispatches to the new `virtual_stream_relay` when `should_use_helper()` (running as SYSTEM, or PUNKTFUNK_FORCE_HELPER; disable with PUNKTFUNK_NO_HELPER). The relay loop feeds the existing send thread — same FEC/seal/paced-send path. Reconfigure rebuilds the output + re-spawns the helper; keyframe requests forward over the control pipe; helper pts_ns (same-machine monotonic clock) is used directly as capture_ns. Disconnect ends the stream (step 6 adds the relaunch watchdog). wgc_helper.rs: reads the stdin control byte to request an IDR; --bit-depth flag threaded through so SDR 10-bit (Main10) negotiation reaches the helper's encoder. cfg-gated windows-only; Linux/macOS build unaffected. Step 5 (DesktopWatcher mux to host DDA on the Winlogon secure desktop) is next. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-16 07:43:20 +00:00
enricobuehler	a0f6cddc70	feat(host/windows): WGC helper subcommand (two-process secure-desktop, step 3) ... `m3-host wgc-helper --target-id N --gdi NAME --mode WxHxHz --bitrate K`: the USER-session half of the two-process secure-desktop design (docs/windows-secure-desktop.md). Opens WGC on the EXISTING SudoVDA output by GDI name only (never creates a virtual output — a second topology owner re-trips the ACCESS_LOST born-lost storm), encodes via NVENC, and ships framed Annex-B AUs on stdout for the SYSTEM host to relay onto the live QUIC session: `[u32 magic "PFAU"][u32 len][u64 pts_ns][u8 keyframe][data]`. tracing → stderr so stdout stays the pure AU stream. cfg-gated windows-only; Linux build unaffected. scripts/headless/win-build.cmd: the canonical box build script (sets PUNKTFUNK_BUILD_VERSION so build.rs stamps the version + the NVENC LIB path).

enricobuehler	8ab262f8f8	feat(trust): host-gated trust-on-first-use — PIN pairing mandatory by default ... TOFU let anyone who could reach the host click "Trust" and stream, which defeats the point on a LAN. Make SPAKE2 PIN pairing the default and only way to trust a NEW host; TOFU survives as an explicit HOST opt-in (for fully trusted networks), advertised over mDNS so clients render their trust UI from the host's policy rather than offering trust on faith. Contract: - Host advertises pair=required (default) or pair=optional. pair=required rejects unpaired clients at the handshake; pair=optional accepts them (TOFU). - Clients: a pinned host whose fingerprint matches connects silently; a pinned host whose fingerprint CHANGED forces re-pairing via PIN (no re-trust shortcut); a NEW host is offered TOFU only if it advertised pair=optional, otherwise PIN pairing is mandatory; a manually-typed or unknown-policy host is always PIN. Host (crates/punktfunk-host/src/main.rs): - m3-host now REQUIRES pairing by default (was open by default). New --allow-tofu opts into accepting unpaired clients + advertising pair=optional; pairing is always armed (PIN logged at startup). serve --native was already secure-by-default (serve --open). The mDNS advert and the accept loop already mapped require_pairing -> pair=required + reject; only the m3-host CLI default + help text changed. Clients honor the advertised policy: - Android (MainActivity.kt): TOFU only for a discovered pair=optional host; manual/unknown -> PIN; fp-change -> re-pair only (dropped the "Forget & re-TOFU" shortcut). - Apple (HostDiscovery/SessionModel/ContentView/HostCards/HostStore): new allowsTofu (pair==optional, distinct from unknown); connect() gates .awaitingTrust on it; unpinned non-optional hosts route to the PIN sheet; "Forget Identity" re-pairs rather than re-TOFUs. - Linux (app.rs/ui_hosts.rs/session.rs): ConnectRequest.pair_required -> pair_optional; initiate_connect routes pinned/fp-changed/optional/else; manual + --connect unknown -> PIN; a pinned connect rejected on trust grounds re-pairs. Docs (CLAUDE.md, README.md, docs-site/content/docs/pairing.md): describe the gated model — PIN is the default, TOFU an explicit opt-in with an impostor warning. Verified: host cargo check/clippy/fmt clean; Android built + live (emulator -> home-worker-2): a manual connect now opens the PIN dialog (no Trust button) and the PIN ceremony streams; Apple swift build clean; Linux clippy -D warnings + fmt clean on the Linux box.

enricobuehler	fe9921cc1c	fix(dist): kill the version-shadow + add build provenance (P0) ... The stale code a default install/upgrade got was a TAG LEAK: deb.yml/rpm.yml shared `tags: ['v*']` with the Apple-client release.yml, so the v0.1.0/v0.1.1 tags cut to ship the macOS app ALSO published host packages versioned 0.1.1 — which outranks every rolling 0.0.1~ciN / 0.0.1-0.ciN build in both registries (dpkg/rpm version compares confirm), so `apt install`/`rpm-ostree install` silently fetched ~99-commits-stale code while the READMEs claimed auto-tracking. Two fixes: - Decouple host publishing from Apple `v*` tags: deb.yml/rpm.yml now trigger on `host-v*` only, so a client tag can never poison the host channel again. - Bump the rolling base 0.0.1 -> 0.2.0 (deb `0.2.0~ciN`, rpm `0.2.0-0.ciN`): sits ABOVE the stray 0.1.1 yet BELOW a future 0.2.0 tag, and still climbs monotonically by run number — so `apt upgrade`/`rpm-ostree upgrade` genuinely move forward. Spec default + build scripts + PKGBUILD pkgver bumped to match. Build provenance (so a stale/shadowed host is detectable): build.rs stamps PUNKTFUNK_BUILD_VERSION (set by CI = the full package version, e.g. 0.2.0~ci120.g802e98d; falls back to the crate version for a plain `cargo build`) into the binary via rustc-env. Surfaced in `punktfunk-host --version`, the startup log, and the mgmt /health + /host `version` field (was a hardcoded CARGO_PKG_VERSION). Deliberately env-driven, not git-derived — the RPM builds from a git-archive tarball with no .git. Version computed BEFORE the build in deb.yml; the spec %build exports it from %{version}-%{release} (and gains --locked for reproducibility parity with the .deb path). Validated: plain build reports 0.0.1, env-stamped build reports 0.2.0~ci999.gdeadbee. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-15 10:30:21 +00:00
enricobuehler	b2e5878711	feat(host/mgmt): HTTPS + token auth by default (no loopback no-auth fallback) ... The mgmt API already always serves HTTPS (the host identity cert), but on a loopback bind with no token it ran unauthenticated — any local process could drive it. Make auth required ALWAYS: - new mgmt_token::load_or_generate(): token precedence is --mgmt-token > env PUNKTFUNK_MGMT_TOKEN > persisted ~/.config/punktfunk/mgmt-token > freshly generated 32-byte hex, persisted 0600 in KEY=VALUE form (so the bundled web console can source it directly as a systemd EnvironmentFile — one source of truth). config_dir() made pub(crate). - parse_serve() resolves the token via load_or_generate() when unset, so a bare `serve` Just Works with auth on and no operator step. - mgmt::run() drops the loopback no-token exemption and requires a token; require_auth()'s unauthenticated fallback now returns 401. The paired-cert (mTLS) branch is unchanged — Apple client + library auth unaffected. - web /api proxy: 503 (legible) instead of forwarding an empty bearer. - tests: test_app/test_app_native default a token, send() auto-attaches the bearer; blank-token test asserts the new "no token" refusal. 80 pass. - docs: mgmt module doc + host.env.example reflect always-on auth + auto-gen. Compiles, clippy/fmt clean, openapi no drift. Part B (bundle the web console into apt, auto-wired to this token) follows.

enricobuehler	5fddaac6af	fix(host): compile punktfunk-host on windows (x86_64-pc-windows-msvc) ... Gate the Linux-only bits so the host crate builds on MSVC (it already built on Linux + macOS): drm_sync/dmabuf_fence use DRM ioctls + libc (a linux-only target dep) and have no non-Linux callers; VirtualOutput.remote_fd is a PipeWire concept. The full dep tree (aws-lc-rs, quinn, rusty_enet, axum) builds clean on MSVC and the binary runs (openapi emits the spec) — only these 3 cfg-gates were needed.

enricobuehler	6351d516e0	feat(host/library): game library API — Steam adapter + custom store ... A new `library` module + four mgmt endpoints surface the host's games to clients (plan: "surface the user's games"). An adapter layer (`LibraryProvider`) so future stores (Heroic/Epic, GOG, Lutris) slot in behind one uniform `GameEntry`. - SteamProvider: reads the LOCAL Steam install — no Steam Web API key, no network. Installed titles from steamapps/appmanifest_<appid>.acf; extra library folders (incl. paths with spaces) from libraryfolders.vdf; candidate roots cover classic, Flatpak and Deck layouts, canonicalized + deduped (the .steam/{steam,root} symlinks all fold to one). Runtimes/redistributables (Proton, Steam Linux Runtime, Steamworks Common, SteamVR) filtered out. Artwork = the public Steam CDN by appid (portrait/hero/logo/header), fetched directly by the client. - Custom store: ~/.config/punktfunk/library.json, write-then-rename persisted, CRUD'd via the API — the "create custom entries via the admin web UI" requirement. - API (under /api/v1, OpenAPI-documented + checked in): GET /library (all stores merged, sorted), POST /library/custom, PUT/DELETE /library/custom/{id}. - `punktfunk-host library` subcommand dumps the resolved library as JSON (diagnostic, mirrors `openapi`). Validated live against the real Steam library on the Bazzite box: 89 appmanifests → 78 games (11 tools filtered), correct titles/sort, and the CDN art URLs return 200. 5 unit tests for the VDF/ACF parsing, tool filter, art URLs, custom mapping.

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

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

enricobuehler	4fff4641bb	feat(discovery): native-protocol LAN auto-discovery over mDNS ... Both the unified host (serve --native) and standalone m3-host now advertise the native punktfunk/1 service over mDNS (_punktfunk._udp) — the analogue of the GameStream _nvstream._tcp advert. TXT records carry proto, the host cert fingerprint (fp, the value clients pin), the pairing requirement (pair=required|optional), and the host id. New crate::discovery module, wired into m3::serve so both host entry points get it; best-effort, never blocks streaming (--connect always works). Client gains `punktfunk-client-rs --discover [SECS]`: browses the LAN and prints each host (name, addr:port, pairing, fingerprint), then exits. Apple clients browse the same service natively via NWBrowser (service type + TXT keys are the contract). Validated cross-LAN: the dev box discovered the GNOME-box appliance (pair=required) and a standalone synthetic host (pair=optional); fingerprint and pairing state correct in both. Also refresh the now-stale sendmmsg caveat in the bitrate doc (batched/paced send landed + validated to 1 Gbps) and mark the encode|send thread split done in §12.

enricobuehler	9a6058cd20	feat(host): §8a — require native pairing by default (serve --open to disable) ... An open punktfunk/1 host any LAN device can trust-on-first-use and stream from is insecure. The unified host now gates native sessions on pairing by DEFAULT: a client must complete the SPAKE2 PIN ceremony (armed from the web console) before it's admitted; paired devices persist. `serve --open` keeps the old TOFU behavior for trusted single-user setups. native_serve_opts now takes a NativeServe { port, require_pairing }; parse_serve builds it with require_pairing = !--open. GameStream pairing (separate) is unchanged. The require_pairing gate + ceremony are already covered by m3::pairing_ceremony_and_gate.

enricobuehler	19666ba57e	feat(host): unified host + native pairing over the management API ... `serve --native` now runs the GameStream host AND the native punktfunk/1 (QUIC) host in ONE process, sharing a single NativePairing handle with the management API — so native pairing is operable from the web console instead of journalctl. - gamestream::serve gains a native_port: spawns crate::m3::serve in the same runtime and passes the shared NativePairing to mgmt::run. Validated live: one process binds both RTSP 48010 and QUIC 9777. - mgmt API: new `native` endpoints — GET /native/pair (status), POST /native/pair/arm (mint a fresh, time-limited PIN to DISPLAY), DELETE /native/pair (disarm), GET/DELETE /native/clients (list/unpair). GameStream-only hosts report enabled:false. OpenAPI regenerated (checked-in doc + drift test). - main.rs: serve --native / --native-port flags. The native host arms pairing on demand (the operator reads the PIN from the console; the SPAKE2 ceremony is host-shows-PIN). New mgmt + native_pairing tests.

enricobuehler	5ca860533e	refactor(native-pairing): extract shared on-demand arming state ... Groundwork for web-UI-driven native (punktfunk/1) pairing. Replaces m3's fixed startup PIN + local paired store with a shared `NativePairing` (new module): arm-on-demand with a fresh, time-limited PIN (`arm(ttl)`), `current_pin()` read per ceremony so a lapsed window stops pairing, plus the trust store (list/add/ remove/is_paired) and a `status()` snapshot. The management API (next commit) and the QUIC accept loop share one handle. CLI `--allow-pairing`/`--require-pairing` still arm at startup (no expiry, PIN logged) — back-compat. m3 pairing ceremony + gate and the C-ABI roundtrip stay green; new unit tests for arm/expire/pair.

enricobuehler	59edeedf07	feat(dualsense): Phase C/D/E — virtual DualSense routing + 0xCC/0xCD planes + C ABI ... PUNKTFUNK_GAMEPAD=dualsense now routes a session's gamepad through a real virtual DualSense (UHID + hid-playstation) end to end: - host: a `PadBackend` enum (m3.rs) selects `GamepadManager` (uinput xpad, default) or the new `DualSenseManager` (dualsense.rs) per session. The manager keeps each pad's full DsState so touchpad + motion (rich-input plane) persist across button/stick frames, and services the !Send /dev/uhid fd only on the input thread (which cycles <=4ms, so the GET_REPORT init handshake completes). - feedback: `service()` now returns `DsFeedback { hidout, rumble }`. Motor rumble stays on the universal 0xCA plane (so non-DualSense clients still feel it; manager dedups change); lightbar / player LEDs / adaptive-trigger effects ride the new 0xCD HID-output plane (host->client) as `HidOutput`. - rich input: touchpad contacts + motion ride the 0xCC plane (client->host) as `RichInput`, applied via `DualSenseManager::apply_rich` (merged with button state; touch normalized 0..65535 -> the touchpad resolution). - connector + C ABI: `NativeClient::next_hidout` / `send_rich_input`, exported as `punktfunk_connection_next_hidout` (-> PunktfunkHidOutput) and `punktfunk_connection_send_rich_input` (<- PunktfunkRichInput); header regenerated. - reference client: `--rich-input-test` drives the DualSense touchpad + motion and logs the 0xCD feedback that comes back. Validated live on-box: a synthetic-source m3-host + client-rs created the real kernel DualSense, drove 0xCC, and decoded 12 live 0xCD events (the kernel's actual lightbar/trigger init reports) with the data plane unaffected (600/600 frames). Adversarial review fixes folded in: the input loop no longer skips the rich drain + feedback pump on a dropped gamepad event, and the touch contact id is clamped to its slot. Remaining: the Apple client renders triggers/rumble on a real DualSense. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-11 08:36:12 +00:00
enricobuehler	2372b02620	feat(host): virtual DualSense via UHID (hid-playstation) — device + report mapping ... Roadmap #5 (rich DualSense). A UHID device presents a real Sony DualSense to the kernel's hid-playstation driver (matched by VID 054C/PID 0CE6), which exposes the full controller — gamepad, motion sensors, touchpad, lightbar/player LEDs, adaptive triggers — unlike the uinput X-Box-360 pad. - inject/dualsense.rs: hand-rolled /dev/uhid codec (no bindgen) mirroring the uinput style; the canonical inputtino 232-byte USB HID report descriptor + the feature-report replies (calibration 0x05 / pairing 0x09 / firmware 0x20) — answering hid-playstation's GET_REPORTs during init is REQUIRED or it creates no input devices. DsState::from_gamepad maps a GameStream/XInput frame → the DualSense input report (buttons/sticks/triggers/dpad, + touchpad/motion fields); service() answers GET_REPORTs and parses HID OUTPUT (rumble / lightbar RGB / player LEDs / adaptive triggers) into quic::HidOutput. - scripts/60-punktfunk.rules: grant /dev/uhid to the 'input' group (like /dev/uinput). - `punktfunk-host dualsense-test`: standalone validation (no streaming session). Validated live: `dualsense-test` → hid-playstation binds + loads ff_memless + led_class_ multicolor; the kernel creates "Punktfunk DualSense 0" (event/js gamepad + Motion Sensors + Touchpad + Headset Jack) at VID 054c/PID 0ce6, plus the lightbar at /sys/class/leds/ input*:rgb:indicator; js shows the Cross button firing + the left-stick sweep. Clippy/fmt clean, workspace tests green. Wiring into the session (pad-type select, touchpad/motion routing, HID-output back-channel) is the next commit.

enricobuehler	9fdc3c3246	feat(headless-kde): reliable bring-up — readiness probe, fix portal ordering/env (roadmap #1 phase 1) ... Headless KDE startup was a chain of timing-sensitive handoffs gated by a blind `sleep 2`, the dominant source of black screens. Phase-1 fixes: - New `punktfunk-host probe-compositor` subcommand: exits 0 iff the detected compositor is up AND ready to create a virtual output now. KWin gets a real check (connect + registry roundtrip + the privileged zkde_screencast global must be advertised — what the backend needs); gamescope/Mutter/wlroots create on demand so the probe just confirms Linux. (vdisplay::probe dispatcher + kwin::probe; reuses kwin.rs's existing roundtrip path.) - run-headless-kde.sh: replace `sleep 2` with an active readiness wait (poll probe-compositor until ready, 30s deadline, and bail with kwin's log if kwin_wayland exits during init). Move the portal restart to AFTER readiness, and precede it with `systemctl --user import-environment` + `dbus-update-activation-environment` (the missing env import — the Sway script does this; without it a restarted portal inherits a stale/empty WAYLAND_DISPLAY, which is the "streams but eats no input/audio" failure). kwin's stderr → a log file. Validated: probe-compositor exits 0 "Kwin ready" against the live session, exit 1 with a clear diagnostic when the compositor is absent. 114 tests green, clippy/fmt clean.

enricobuehler	ff4fe197be	fix(punktfunk/1): adversarial-review fixes — SPAKE2 pairing, renegotiation hardening, +more ... Triaged the multi-agent review of the renegotiation + pairing + Sway + AV1/surround batch (1 critical, 11 major/minor confirmed). Fixes: CRITICAL — PIN pairing was offline-brute-forceable. The HMAC-of-PIN proof let an active MITM who terminates the TOFU ceremony recover the 4-digit PIN by offline dictionary search (all other inputs observable) and forge a correctly-bound proof. Replaced with **SPAKE2** (balanced PAKE, `spake2` crate) + key-confirmation MACs, binding both cert fingerprints as the SPAKE2 identities: an attacker gets exactly ONE online guess, no offline search, and mismatched cert views (a real MITM) never reach a shared key. Also reworked the UX to an "arming PIN" — one PIN per arming window shown at host startup (the SPAKE2 client needs the PIN to build its first message, so it can't be minted per-connection). Validated live: wrong PIN rejected in 0.1s, right PIN pairs + persists + the paired identity streams. Pairing hardening: `--allow-pairing`/`--require-pairing` must arm pairing (default rejects unsolicited ceremonies); per-host cooldown bounds online guessing; the client flushes its CONNECTION_CLOSE so a refused ceremony can't wedge the sequential host for the full timeout; atomic (temp+rename) paired-store writes. Protocol: control/pairing messages use a distinct CTL_MAGIC (PKFc) — fully disjoint from the positional Hello namespace (a future abi_version can't be misparsed as a control message); all typed decodes are length-exact. ABI_VERSION → 2 (punktfunk_connect signature gained the identity params; header regenerated). Renegotiation: drain the reconfig channel to the NEWEST mode (one rebuild, not one per stale step); validate refresh_hz; build the new pipeline BEFORE dropping the old so a rebuild failure keeps the session on its current mode instead of killing it. GameStream: packetDuration snaps to {5,10} (an in-between value isn't a legal Opus frame size and would kill audio). Sway: chooser file moved to $XDG_RUNTIME_DIR (was a fixed world-writable /tmp path — DoS / capture-misdirection by another local user). Swift: fixed two compile breakers in the new pairing/identity APIs (Int32 status .rawValue, UInt cap cast). New SPAKE2 + namespace-disjointness + pairing-roundtrip unit tests; the in-process pairing test now also exercises the arming PIN + cooldown. 114 tests green, clippy -D warnings clean (both feature sets), fmt, C-ABI harness.

enricobuehler	4d26ac5c85	feat: punktfunk/1 — mid-stream mode renegotiation + PIN pairing ceremony ... Renegotiation (no reconnect on resize): the handshake bi-stream stays open; the client sends Reconfigure{mode} (typed post-handshake message), the host validates + acks Reconfigured and rebuilds capture/encoder/virtual output at the new mode while the data plane (keys, ports, FEC) runs untouched — the first new-mode AU is an IDR with in-band parameter sets. NativeClient::request_mode / punktfunk_connection_request_mode; mode() reflects the active mode. Validated live on KWin: one continuous stream, 225 frames @1280x720 then 395 @1920x1080, ~90 ms pipeline rebuild (ffprobe shows both resolutions). PIN pairing (mutual trust, kills TOFU MITM): clients get persistent self-signed identities presented via QUIC client auth (generate_identity / client auth offered but optional server-side — legacy clients still connect). Ceremony on the control stream: PairRequest{name} → host shows a 4-digit PIN (log) + PairChallenge{salt} → client proves with HMAC-SHA256(PIN‖salt, client_fp‖host_fp) — binding both certs means a MITM can't forward a proof, single attempt per PIN, constant-time compare → PairResult; host persists the fingerprint (~/.config/punktfunk/punktfunk1-paired.json), client pins the host's. m3-host --require-pairing gates sessions on the paired set. NativeClient::pair + punktfunk_pair/punktfunk_generate_identity in the ABI; reference client: --pair PIN --name LABEL + auto-generated persistent identity, --remode for live renegotiation testing. Swift wrapper: ClientIdentity/generateIdentity()/pair(), requestMode()/currentMode(); README handoff updated. Tested: reconfigure/pairing wire roundtrips, C-ABI mode switch ack, full in-process ceremony (wrong PIN → Crypto, anonymous-vs-gate rejection, success → pinned session); live wrong-PIN ceremony against the serving host (PIN logged, proof rejected).

enricobuehler	bfd64ce871	rename: lumen → punktfunk, everywhere ... Full project rename, decided 2026-06-10: - Crates/binaries: punktfunk-core / punktfunk-host / punktfunk-client-rs. - C ABI: punktfunk_* symbols, Punktfunk* types, include/punktfunk_core.h, PUNKTFUNK_FEATURE_QUIC guard (header regenerated; cbindgen renames updated, incl. PUNKTFUNK_BTN_*/PUNKTFUNK_AXIS_* wire constants). - Protocol: punktfunk/1 — control-plane magic LMN1 → PKF1, nonce salt lmn1 → pkf1. WIRE BREAK: clients must be rebuilt from this revision. - Env knobs: PUNKTFUNK_VIDEO_SOURCE / PUNKTFUNK_COMPOSITOR / PUNKTFUNK_ZEROCOPY / …. - Host config dir: ~/.config/punktfunk (the box's dir was migrated in place — the persistent identity is unchanged, pinned fingerprints stay valid). - Swift package: PunktfunkKit + PunktfunkCore.xcframework + PunktfunkConnection (Sources/PunktfunkClient app + tests renamed with it); build-xcframework.sh updated. - scripts/: 60-punktfunk.rules, punktfunk-host.service; OpenAPI doc regenerated. Also: scripts/headless/run-headless-kde.sh — full headless Plasma bringup. Root cause of "desktop but no apps/settings" over the stream: plasmashell launched without XDG_MENU_PREFIX=plasma-, so the launcher resolved a nonexistent applications.menu and rendered an empty menu. The script sets the complete KDE session env (menu prefix, KDE_FULL_SESSION, session version) and rebuilds ksycoca before starting plasmashell. Gate: 97/97 tests, clippy -D warnings (both feature sets), fmt, C-ABI harness PASS, zero lumen references left outside .git.
