Underneath, `4fde0e94` added: G2 pooled GPU cull over shared storage arenas (`rendering/occlusion_culling/gpu_cull_pooled`, game dial `env gpucull pool`), a fixed shadow LOD band for gpu-culled MultiMeshes (`gpu_cull_shadow_fixed_band`, `env gpucull shadowband`) and the `STATIC_SHADOW_AT_REST` shader built-in (`static_casters_at_rest`, `env gpucull staticrest`); all default off. GodotSharp regenerated (API + Tools). Oracles on Metal: `multimesh_cull_pool` 4524/4524, `draw_indirect_count` 24/24. Windows is also engine `4fde0e94` as of 2026-10-18 — Forge built it in parallel with the Mac (`.agents/handoffs/forge-windows-g2-4fde0e94.md`), so both platforms and the `4.7.2@4fde0e94d` pin (the game's `tree_wind.gdshader` uses the new built-in) share one hash. Underneath is the `9dcc5d458` pair (SSCS contact shadows, hero shadow min-combine, upstream 4.8 shadow fixes #121775/#124348 with the game sun bias 0.014, `draw_list_draw_indirect_count`), where the D3D12 oracle on RTX 5080 was 22 passed / 2 failed — the base-instance pair, the documented D3D12 gap (`.agents/handoffs/forge-windows-sscs-9dcc5d45.md`); `--gpu-validation` needs the D3D12 debug layer, which Forge lacks (Graphics Tools not installed). Still owed on Windows: `multimesh_cull_pool` oracle (gates making pool the default), the validation pass, and in-world checks (`herocombine`, `contactshadow`, SSCS in `--gpu-profile`, sun acne at bias 0.014, pooled gpucull census).
