NugetStore.GetLocalPackages mirrors newer local-folder .nupkgs into the global cache so dev Stride.* shadows public versions. Drops the metadata-delete in StrideAutoPackDeploy (the mirror replaces it), adds stride-local + Stride.* mapping in nuget.config, bumps Microsoft.Build / NuGet / DependencyModel to the .NET 10 SDK versions.
NuGet skips re-extracting when the version matches, leaving stale DLLs in consumer bins. Remove the extracted dir after each pack.
…ructure The new Stride.Games.AutoTesting + sample-screenshot pipeline replaces the SamplesTestServer / ConnectionRouter / Games.Testing path end-to-end. ConnectionRouter stays — Game Studio, EffectCompilerServer and TestRunner still use it.
End-to-end screenshot regression pipeline for samples. * Stride.Games.AutoTesting harness — drives input, captures PNGs, writes done.json. * In-proc LPIPS-AlexNet comparator + optional Claude-vision fallback for non-deterministic frames. * xunit Theory wrapper discovers fixtures from tests/samples/*.cs and runs regen + build + launch + compare per sample. * GH Actions matrix: D3D11 gating, D3D12/Vulkan best-effort (Vulkan via Lavapipe), daily schedule + manual update-baselines workflow.
ConfirmRenderingSettings clamps the requested back-buffer size to fit Window.ClientBounds — fine for dev, wrong for headless CI capture (a portrait 640x1136 sample gets clipped to 640x749 on a shorter desktop). Adds SkipBackBufferClampToWindow on GraphicsDeviceManager (copied to PresentationParameters in ChangeOrCreateDevice). ConfirmRenderingSettings honours it; the Vulkan swap-chain creation also bypasses surfaceCapabilities.currentExtent when set. The autotesting harness sets the flag in OnGameStarted, before device creation.
