+# Forge (Windows) — rebuild pair from engine main ≥ 615e852f, re-judge the render verdicts, pin (2026-10-05)
+
+macOS pair `615e852f` (code `c76f2ecc`) is published here. Windows is still `b1bc0aef` (2026-09-28).
+
+1. Build the Windows editor + console pair from `tinqs/engine` main with the `windows-x64` manifest flags
+   (`platform=windows target=editor arch=x86_64 module_mono_enabled=yes d3d12=yes angle=yes accesskit=yes`),
+   regenerate GodotSharp from that exact binary, smoke (0 wrapper errors), publish here, update `manifest.json` +
+   `README.md`.
+2. Then pin `tinqs/required_engine_build="4.7.2@<hash7+>"` in `ariki-game/project.godot` (both platforms on the same commit).
+3. Re-judge on Windows what the Mac measured (frame GPU-bound on M1): static shadow cache default (now OFF on Apple
+   silicon game-side, ON elsewhere — keep ON on Windows only if `inverted` ≥ `cache_off` fps), GPU veg bands, HLOD.
+   Full recipe + numbers: `ariki-game/.agents/handoffs/2026-10-05-forge-windows-render-bench-handover.md`.

-Mac is engine `51ed21d5` as of 2026-10-05 (`--version` prints `4.7.2.stable.mono.custom_build.51ed21d5d`): 4.7.2 + static shadow cache (tile budget, live caster screen-size cull, inverted-contract switch) + the video adapter memory query + GPU device-lost diagnostics (engine wiki `shadow-pass-diet-2026-10-05.md`, `gpu-device-lost-diagnostics.md`). Windows is `2caca361` (2026-10-03, built by UyGar: `b1bc0aef` + the video adapter memory query; no 2026-10-05 round yet) until Forge rebuilds from main. The engine source repo stays private. Check `manifest.json` for sha256. The 4.7 Windows cutover handoff is resolved: [`.agents/handoffs/forge-windows-4.7.md`](.agents/handoffs/forge-windows-4.7.md).

Windows is `b1bc0aef` (2026-09-28, 4.7.2 + static shadow cache) and gets all of the above when Forge rebuilds from main - do not pin `required_engine_build` before that.
