"note":"Windows carries 9dcc5d458 \u2014 SAME hash as macos-arm64 (built at 9dcc5d458f, the docs-only commits 91b11b70/a77eb1781 excluded so both platforms and the 4.7.2@9dcc5d458 pin share one hash): screen-space contact shadows for directional lights (SSCS, default off, env contactshadow dial), hero shadow min-combine (instance_light_directional_set_hero_shadow_spot), tight cascade caster culling on the real cascade frustum (#121775), shadow bias no longer shrunk by blur < 1 (#124348; game sun ShadowBias 0.014 applies with this pin), RenderingDevice.draw_list_draw_indirect_count (D3D12 native path). GodotSharp regenerated from this binary \u2014 Api AND Tools (InstanceLightDirectionalSetHeroShadowSpot + DrawListDrawIndirectCount present). Checks: headless game boot clean (0 binding errors); oracle draw_indirect_count on D3D12 (RTX 5080): 22 passed, 2 failed \u2014 the 2 base-instance cases are the documented D3D12 gap (shaders do not see base instance there yet; expected-fail per draw-indirect-count.md). WITH --gpu-validation the D3D12 run could not start (debug layer not installed on Forge \u2014 Graphics Tools owed); validation-layer cleanliness still to verify. In-world checks (herocombine, contactshadow, SSCS in --gpu-profile, sun acne with bias 0.014) still owed on Windows. Editor target only \u2014 template_release in this folder is still the 1e7be28b tree. D3D12 Agility DLLs (D3D12Core.dll, d3d12SDKLayers.dll) are NOT shipped \u2014 the game runs Vulkan, same decision as 2026-10-05. Crash-report checklist (8 steps) also still owed on Windows."
