-      Preloaded by full path so dxcompiler's own plain-name load resolves to it
-      and the DXIL leaves signed; spirv_to_dxil queries its validator version to

+      The only shader library the backend still needs. Loaded by full path from
+      the D3D12 folder next to the executable, then by plain name from the
+      system search path, because the signer's own plain-name load skips
+      D3D12/. D3D12 rejects an unsigned shader, so PipelineCache::Initialize
+      stops when IsSignerAvailable() is false and asks for a recent dxil.dll in
+      the D3D12 folder; that failure propagates to "Failed to setup
+      graphics_system!" (src/xenia/emulator.cc:427-431). Windows defaults to
+      gpu = "d3d12" (src/xenia/app/xenia_main.cc:70) and the backend factory
+      only falls back when D3D12GraphicsSystem::IsAvailable() is false, which
+      tests the D3D12 API itself, not the redistributable. Taken from
+      bin/x64/dxil.dll in dxc_2026_05_27.zip of DirectXShaderCompiler release
