The MIT OR Apache-2.0 SOURCE license is clean (audit found no copied copyleft); the
gaps were all binary-distribution (Layer-2). This makes the shipped artifacts honest:
- Windows host + client: bundled FFmpeg BtbN gpl-shared -> lgpl-shared (AMF/QSV/decode
unaffected; the GPL-only x264/x265 were never used), and ship the FFmpeg LGPL notice
+ license text in the installer + MSIX (licenses/).
- THIRD-PARTY-NOTICES.txt generated + bundled into installer/MSIX/deb/rpm. Offline
generator (scripts/gen-third-party-notices.{py,sh}) + cargo-about config (about.toml/
.hbs) with a permissive-only accepted-license allow-list as a copyleft regression gate.
- Reword the win32u GPU-preference hook comments to reflect independent reimplementation
(no Apollo/Sunshine GPL-3.0 source copied).
- README dual-license + inbound=outbound contributor clause + non-affiliation trademark
disclaimer; new CONTRIBUTING.md.
- LICENSE files into the standalone driver + vk-layer workspaces; deb copyright holder
aligned to "unom and the punktfunk contributors".

- Add the centered punktfunk wordmark banner at the top (assets/punktfunk-logo.svg,
the same logo + layout the marketing site's README uses).
- Refresh the now-stale Windows-host facts: all-vendor (NVENC + AMF/QSV), its own
all-Rust pf-vdisplay IddCx virtual display (was SudoVDA), bundled UMDF virtual-gamepad
drivers (ViGEmBus gone), HDR incl. Vulkan-game HDR; x64-only, no longer NVIDIA-only.
- Note punktfunk-host covers Linux + Windows; point design/ at its new README index.

The Android app is in Google Play Internal Testing, so the public Play Store URL
doesn't resolve for non-testers. Lead the Android install instructions with a
"request a tester invite on Discord" CTA (the Play listing unlocks once a Google
account is added to the test track), and surface the Discord + r/Punktfunk
community links in the README, the docs intro, and the docs-site nav.

Drop the "Linux-first" framing across the README and docs site in favor of
first-class Linux AND Windows hosts, and surface the Windows IDD-push
virtual-display path as a distinct differentiator (punktfunk's own indirect
display driver the host pushes frames into — a real virtual display, no physical
monitor or dummy plug, even on the secure desktop).

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.

Refresh the README and documentation for public visitors:
- README: public-facing rewrite with accurate status for all four native
clients (macOS, Linux, Windows, Android) and the Windows host.
- docs site: fix stale client status (Android is a full client, not a
scaffold; Windows client is stage-1 complete + signed MSIX), add the
missing Android client section, correct "which client" guidance.
- Windows host: corrected from "deferred/scoped" to implemented & shipping
(NVIDIA-only, x64-only) across windows-host, roadmap, status,
requirements, running-as-a-service, and the README.
- Remove internal infrastructure from public docs (box names, private IPs,
SSH/token commands, deploy topology); rewrite status.md as a public
project-status page; sanitize ci.md and implementation-plan.md.
- Update clients/android and clients/apple READMEs to current state.

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.

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.

Make the host docs match the real distribution path and the actual CLI. Reviewed by a
multi-agent pass (6 editors against one verified fact sheet + an accuracy reviewer); its
findings (a wrong client-Recommends claim, a native-concurrency overstatement) folded in.
- Install front door: new README "Install (host)" method-picker + docs-site/install.md
(+ nav), routing each distro to its package registry; source build demoted to a fallback.
- Registry-first install: ubuntu-gnome/ubuntu-kde now lead with the apt registry (not a
cargo build); bazzite leads with the Gitea RPM registry (was COPR/source). Source builds
moved to an appendix.
- CLI accuracy: serve --native arms pairing from the web console (NOT --allow-pairing, which
with --require-pairing/--max-concurrent is m3-host-only); --open disables mandatory pairing.
host-cli/configuration/pairing/quickstart/troubleshooting corrected; mgmt API documented as
always HTTPS+token. Native host serves one session at a time (extras queue) — not multi.
- Firewall: real ports documented (native UDP 9777 + the ephemeral data port caveat +
GameStream ports) for Debian + Arch (ufw + nftables), not just Bazzite.
- Sync/accuracy: punktfunk-client (GTK4) presented as a shipping client (not "roadmap"),
punktfunk-client-rs as the headless tool; host Recommends punktfunk-web only (not the
client); COPR chroots f43/44; bootc header says Gitea registry not COPR.

Per the new docs workflow (docs-site = KB layer; repo docs/ keeps design notes):
- Add a canonical Status & Progress tracker (status.md): milestones, per-box live
state, and a dated progress log — the go-forward place to track progress.
- Add setup guides: GNOME/Mutter host (gnome-box — Secure Boot MOK enroll, the
libnvidia-gl EGL fix, autologin, screen-lock disable, appliance unit), headless
KDE box, and Bazzite host (ujust input group, gamescope session, gotchas).
- Roadmap is now canonical in docs-site (synced the skew-handshake section 12
update); removed the repo docs/roadmap.md copy and repointed README to docs-site.
- Nav (meta.json) + landing cards updated; site builds (bun run build).

- README: replace the stale M0/M2-in-flight status with reality — M1 hardened, M2
GameStream host live to stock Moonlight, M3 punktfunk/1 validated, M4 Apple first
light, web console + unified host; FFmpeg 7/8; Bazzite-deployed. Layout adds
web/, packaging/, native_pairing, dualsense.
- CLAUDE: protocol-growth item now reflects the unified host + web-console native
pairing (done) and flags the next steps; layout updated.
- roadmap §7 Windows: de-risked via SudoVDA (the Sunshine Virtual Display Adapter) —
no self-signed kernel IDD needed; the virtual-display backend drops XL→M.
- roadmap §8 (new) Pairing & trust hardening: mandatory PIN pairing by default
(TOFU-open is insecure on a LAN) + delegated pairing approval (an already-paired
device approves a new one, no out-of-band PIN).
- windows-host.md: SudoVDA path throughout (status, table, phasing, effort M not L).

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.

The clients/apple scaffold is now a working macOS client, validated live against this
repo's host across the LAN: gamescope virtual output → NVENC HEVC → lumen/1 (GF(2¹⁶) FEC +
AES-GCM over UDP, QUIC control) → VideoToolbox → AVSampleBufferDisplayLayer at 720p60,
mouse/keyboard flowing back as QUIC datagrams into the host's gamescope EIS injector
(~3.7k events injected in one session).
LumenKit:
- LumenConnection: the predicted cbindgen compile fixes (C17 header spells the typedefs as
integers while the enum constants import as a distinct Swift type — bridge by rawValue);
close() is now safe from any thread (a close flag + pumpLock held across the blocking
poll enforce the C contract "never close with a next_au in flight"; flag prevents
lock-starvation by back-to-back polls).
- StreamView: per-pump cancellation token (reconnects can't double-pump), flush + re-gate
on the next in-band parameter sets when the layer fails, no stale enqueue after restart.
- InputCapture: fractional-delta accumulation (sub-pixel motion isn't truncated away),
pressed-state tracking with release-all on focus loss and stop() (nothing sticks down
host-side), global-singleton ownership guard (GC has one handler slot per process),
X1/X2 buttons, horizontal scroll, full keypad/CapsLock/ISO-102nd/PrintScreen/Menu VKs.
- LumenClient app shell (swift run LumenClient): connect form, fps/Mb-s HUD,
LUMEN_AUTOCONNECT/LUMEN_MODE for scripted first-light runs.
- Tests: Annex-B byte-level units; real-codec round trip (VTCompressionSession-encoded
HEVC rebuilt as the host's wire shape → AnnexB → VTDecompressionSession → pixels);
test-loopback.sh (Swift client vs a real local m3-host over loopback — the Swift twin of
c_abi_connection_roundtrip); RemoteFirstLightTests (full pipeline over the LAN).
Host/build fixes that fell out:
- The workspace builds on non-Linux again: gamestream audio (opus) and sendmmsg batching
are now platform-gated with stubs/fallback, per the crate's "compiles everywhere" rule.
- Horizontal scroll was inverted end-to-end: the injectors negated BOTH axes onto the
ei/wl axes, but GameStream's horizontal convention is positive = right
(moonlight-qt/Sunshine pass it through unnegated) — only vertical flips now. This also
un-inverts real Moonlight clients.
- AnnexB drops all zeros preceding a start code (trailing_zero_8bits padding), ffmpeg's
policy, instead of leaking them into the preceding NAL.
- build-xcframework.sh: deployment targets pinned to the package floor + an otool guard —
cargo does not fingerprint MACOSX_DEPLOYMENT_TARGET, so warm caches can silently ship
too-new minos objects.
Adversarially reviewed (5-dimension multi-agent pass, every finding refutation-verified):
14 confirmed findings, all fixed above; the send-while-polling core-contract gap flagged
here is closed by the lumen/1 session-planes work (&self pulls + per-plane borrow slots).

Five confirmed findings from a 46-agent review panel:
- Empty --mgmt-token no longer satisfies the non-loopback token gate
(critical: 'Bearer ' with an empty token authenticated; parse_serve now
bails on blank tokens and mgmt::run treats blank as none)
- axum's built-in body rejections (400/415/422) now wear the documented
ApiError envelope via an ApiJson extractor, and the spec documents them
- GET /health carries security([{}]) in the spec, matching the server's
auth exemption
- unpairClient's description no longer claims revocation the TLS layer
doesn't enforce yet (gamestream/tls.rs accepts any cert — known gap)
- CLAUDE.md/README.md no longer reference the deleted web.rs
