The July 2026 windows-rs brings a reconciler keyed-child-order fix (#4728), widget
validation (#4727), a DPI collision fix (#4751), icon elements (#4736), multi-window
support (#4730) and scroll virtualization (#4710) — the re-render fixes the Windows
client has been working around at the architecture level. All three pinned deps
(windows-reactor, windows, windows-reactor-setup) move together so windows-core
stays unified across the swap-chain hand-off, and pf-client-core moves with them.
The bulk of the diff is #4689: windows/windows-sys now generate straight from the
Windows SDK, so the `Win32_*` namespace features became one feature per SDK header
(winuser, dxgi, d3d11, …), the PascalCase namespace modules became header-named
modules, struct-returning COM methods take explicit out-params and return HRESULT,
Win32 functions return their raw BOOL/HANDLE instead of Result, and flag constants
are plain integers. Both crates' Win32 code is rewritten to that shape; behaviour
is unchanged on every path.
Riding along, all already stale before the bump: the README and the three Windows
workflows stop claiming windows-reactor's build.rs needs CARGO_WORKSPACE_DIR (that
build.rs no longer exists — staging moved to windows-reactor-setup via OUT_DIR);
the README layout section stops describing modules that moved into the session
binary long ago and gains the manual smoke checklist; the notices generator learns
the SPDX for crates that ship license files without a `license` field, which turns
windows-reactor-setup's UNKNOWN into MIT OR Apache-2.0; and the crate records its
real rust-version (1.96) instead of inheriting the workspace's 1.82.
Verified: cargo check/clippy/fmt clean on punktfunk-client-windows, pf-client-core
and punktfunk-client-session; both bins build; --discover finds the LAN hosts; the
GUI shell comes up (WinAppSDK bootstrap intact under the new reactor-setup).

Clients want to show which OS/distro a host runs. The host now detects it once
per process (new osinfo module: compile-time on Windows/macOS, os-release on
Linux) and advertises an icon-friendly specificity chain, generic → specific —
`windows`, `macos`, `linux[/<family>][/<id>]`, e.g. `linux/fedora/bazzite`,
`linux/arch/steamos`. A client walks the chain most-specific-first and shows the
first token it has art for, so an unknown distro degrades to its family's mark
and finally to plain Tux — the host emits the full chain precisely so clients
need zero distro→parent knowledge. The middle token is the first recognized
ID_LIKE ancestor (the spec orders them most-similar-first); the leaf is ID
verbatim, sanitized to TXT-safe `[a-z0-9._-]` because it feeds a DNS record.
Two carriers, both additive: a new advisory mDNS `os=` TXT key (same trust
posture as `mac` — unauthenticated, a wrong value only draws a wrong icon), and
`HostInfo.os` + `HostInfo.os_name` on the mgmt API (`os_name` is the os-release
PRETTY_NAME, REST-only so the TXT stays small). GameStream serverinfo and the
QUIC Welcome are untouched. api/openapi.json regenerated (drift test green on
Linux) and the TS SDK gen refreshed from it — which also catches the committed
gen up with earlier spec changes it had missed (monitors, native_paired_clients,
encoder_backend).
assets/os-icons/ gains the ten master SVG marks every client derives its
per-platform art from (Font Awesome Free brands CC BY 4.0 + Simple Icons CC0 —
provenance in its README), with attribution folded into THIRD-PARTY-NOTICES.txt
via the generator (regenerating also catches the stale crate manifest up with
the current lockfile).

plan §4.6 + Phase 3 productization:
- Pinned bitrate: an Automatic client (bitrate 0) on a PyroWave session
resolves to the codec's ~1.6 bpp operating point for the mode (≈200
Mbps at 1080p60) instead of the 20 Mbps H.26x default; explicit rates
are honored. Mid-stream SetBitrate retargets are refused with the
pinned rate acked (guards old/foreign clients), and the client-side
AIMD controller + startup capacity probe stay off for the codec — no
rate descent into wavelet mush, no climb probe whose VBV reasoning
doesn't apply to hard per-frame CBR. Unit-tested.
- All-intra silencing: the data plane drops drained keyframe/RFI
requests on PyroWave sessions (the next frame IS the recovery), so
the forced-IDR cooldown, RFI attempt, and storm coalescing never run.
- Opt-in UI: 'PyroWave (wired LAN)' joins the console's Video-codec
cycler; trust::Settings maps it to CODEC_PYROWAVE. Safe everywhere by
the negotiation contract — an un-advertised preference falls back
through the ladder.
- FEC: decision recorded — adaptive FEC (10% start, loss-report driven)
stays as-is for the MVP opaque-AU mode; the FEC≈0 policy belongs to
the Phase-4 datagram-aligned mode.
- THIRD-PARTY-NOTICES: the generator now lists third-party trees
vendored inside first-party crates (pyrowave, Granite subset, volk,
Vulkan-Headers) with their full license texts; file regenerated.
- docs-site: 'PyroWave (wired-LAN codec)' page — what it is, the
bandwidth table, how to enable it, current limits.
Validated on .21: 309 host + 148 core + 26 client tests green,
console-ui clean, both feature configs.

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".
