"unom" alone is not the legal entity name. Updated the copyright line in
all nine first-party license files -- the root MIT/Apache pair and the
hand-maintained copies under clients/apple, clients/decky,
packaging/windows/drivers and packaging/windows/pf-vkhdr-layer (there is
no script that syncs these, so each is edited directly).
The Linux and Windows clients' About screens pick this up automatically:
both `include_str!` the root LICENSE-MIT / LICENSE-APACHE at compile time.
Deliberately untouched:
- Third-party license texts (Geist OFL, FFmpeg, VB-CABLE, the vendored
pyrowave/Granite tree, KDE protocol XMLs, the os-icon licenses) -- those
are other parties' copyrights.
- Publisher/author/maintainer metadata, which is identity rather than
license text and is reported separately for a decision.
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".

NVIDIA/AMD Vulkan ICDs refuse to *advertise* an HDR color space for a surface on an
IddCx indirect/virtual display, so Vulkan games (Doom: The Dark Ages, id Tech, Indiana
Jones, …) report "device does not support HDR" — even though Windows HDR, DWM compose,
and the client PQ stream all work, and the ICD happily *accepts + presents* a forced HDR
swapchain there. The whole gap is enumeration; the community (Apollo/Sunshine/VDD) wrote
this off as kernel-side / unfixable.
Add VK_LAYER_PUNKTFUNK_hdr_inject (packaging/windows/pf-vkhdr-layer/): a standalone
cdylib Vulkan implicit layer that appends {A2B10G10R10, HDR10_ST2084} + {RGBA16F, scRGB}
to vkGetPhysicalDeviceSurfaceFormats[2]KHR (no need to hook vkCreateSwapchainKHR — the
ICD doesn't validate the color space there). Self-gated on the surface monitor's actual
advanced-color state (DisplayConfig GET_ADVANCED_COLOR_INFO), so it is a complete no-op
on SDR sessions and real monitors (dedup). Always-on (registry-discovered) so it works
regardless of how a game is launched — env-scoping silently fails for already-running
Steam. Escape hatches: DISABLE_PF_VKHDR, PF_VKHDR_EXCLUDE, and a built-in kernel-anti-
cheat denylist.
The installer builds/signs/stages it and registers it under
HKLM64\SOFTWARE\Khronos\Vulkan\ImplicitLayers (opt-out "Install the HDR Vulkan layer"
task); windows-host CI fmt+clippy-gates it (msvc-only FFI).
Live-validated on the RTX box: Doom: The Dark Ages enables HDR over the pf-vdisplay
virtual display.
