"note":"Mac. Engine 9dcc5d45 = 7fb81364 + screen-space contact shadows for directional lights (backport of upstream 4.8 #118045/#123814; ProjectSettings rendering/lights_and_shadows/contact_shadow/{enabled,shadow_length,surface_thickness}, Light3D.shadow_contact_shadows_allow/blur, RenderingServer.light_set_allow_contact_shadows; default off, game dial env contactshadow; ~0.43 ms on M1 Max), hero shadow min-combine (RenderingServer.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; the game retunes the sun ShadowBias 0.04 -> 0.014 with the pin), RenderingDevice.draw_list_draw_indirect_count (Metal emulation; oracle 24/24 on M1 Max). GodotSharp regenerated from this binary (API + Tools). Smoke: the owner's game in-world, horizon + static prefill OK, hero combine on, contact shadows on/off, ~72 fps, no new error types. windows-x64 is STILL 7fb81364b: Forge must rebuild from engine main (handoff .agents/handoffs/forge-windows-sscs-9dcc5d45.md). The game pin is 4.7.2@9dcc5d458, so Windows engines are refused until that publish (owner's call, 2026-10-18)."
"note":"Windows carries 4fde0e94d — engine main = 9dcc5d45 (SSCS + hero combine + shadow fixes + draw_indirect_count, see that pair) PLUS 4fde0e94d7 G2 pooled cull: one reset + one cull dispatch per camera render over shared arenas (multimesh_gpu_cull_set_pooled / project setting rendering/occlusion_culling/gpu_cull_pooled, DEFAULT OFF), fixed shadow band (multimesh_gpu_cull_set_shadow_fixed_band, multimesh_set_gpu_shadow_band), STATIC_SHADOW_AT_REST spatial built-in, multimesh_get_cull_command_offset; either shadow switch re-renders every static tile. Validated on M1 Max Metal pre-push (doctests 7/7, multimesh_cull_pool oracle 4524/4524, draw_indirect_count 24/24, StaticShadow 21/21). GodotSharp regenerated from this binary — Api AND Tools (MultimeshGpuCullSetPooled + MultimeshGpuCullSetShadowFixedBand + MultimeshSetGpuShadowBand present). Headless game boot clean (0 binding errors). Windows oracle for multimesh_cull_pool NOT yet run (D3D12 base-instance gap may bite the pooled draws — owed). Game pin set to version-only 4.7.2: macos-arm64 is still 9dcc5d45 — when Kraken publishes 4fde0e94d, pin 4.7.2@4fde0e94d. In-world gpucull checks (pooled on/off, census via multimesh_get_cull_command_offset, shadow band) still owed on Windows. Editor target only — template_release still 1e7be28b. D3D12 Agility DLLs not shipped (Vulkan game). Crash-report checklist (8 steps) also still owed."
