engine(windows-x64): publish 2caca361 — b1bc0aef + get_video_adapter_memory

Windows editor built from tinqs/engine 2caca361 on UyGar's machine (2026-10-03),
the build ariki-game's settings/hardware lane has been running on. --version
prints 4.7.2.stable.mono.custom_build.2caca3619; d3d12, angle and accesskit
confirmed present in the binary.

GodotSharp regenerated from this binary (glue has Terrain3D +
GetVideoAdapterMemory) and replaced wholesale: nupkgs are 4.7.2 only (the game
pins Godot.NET.Sdk/4.7.2), and the stray nested GodotSharp/GodotSharp copy is
gone (the Mac layout never had it).

Not included: the 2026-10-05 round (shadow pass diet, staggered/fit cascades,
shadow_lod_bias, GPU MultiMesh cull Stage A/B). ariki-game guards each of those
(HasMethod checks, ProjectSettings no-ops), so the game runs; those knobs just
do nothing on Windows until a build from main.

+# Handoff → Forge (Ozan's Windows box): rebuild windows-x64 with the static shadow cache (2026-09-28)
+
+**From:** Fable orchestrator on the Mac · **Why:** `tinqs/engine` main gained the directional static shadow cache
+(Part 1) and the stepped-sun crossfade (Part 2) — Forward+ renderer, new project settings, six+four
+`RenderingServer` methods, a second depth atlas. The game (`ariki-game` ≥ 19490e358) calls the new methods by
+name and degrades loudly on an engine without them, so Windows teammates keep working on the old binary but get
+no cache. Rollout plan: `ariki-game/.agents/handoffs/2026-09-28-static-shadow-cache-rollout.md`.
+
+## Steps (mirror of `forge-windows-4.7.md`, same toolchain as the fec9847 build)
+
+1. `cd engine && tinqs pull` → `git log --oneline -1` must show the Part 2 commit named in the rollout plan.
+2. Build (the flags recorded in `manifest.json` for fec9847):
+   ```
+   scons platform=windows target=editor arch=x86_64 module_mono_enabled=yes d3d12=yes angle=yes accesskit=yes
+   scons platform=windows target=editor arch=x86_64 module_mono_enabled=yes d3d12=yes angle=yes accesskit=yes windows_subsystem=console
+   ```
+3. Regenerate glue + GodotSharp (matched-pair law — do not skip even though no C# binding is *required* by the
+   compiler; the manifest promises the pair):
+   ```
+   bin\tinqs.windows.editor.x86_64.mono.exe --headless --generate-mono-glue modules\mono\glue
+   python modules\mono\build_scripts\build_assemblies.py --godot-output-dir=bin --godot-platform=windows
+   ```
+4. Copy into this repo: `engine/windows-x64/tinqs.windows.editor.x86_64.mono.exe`, `...mono.console.exe`, and the
+   whole `GodotSharp/` (replace, never merge).
+5. `manifest.json` → `engine.windows-x64`: `version` (from `--version`), `engine_commit`, both sha256s, `built_on`,
+   `built_by`, `note` ("static shadow cache Part 1 + Part 2; GodotSharp regenerated"). Leave `macos-arm64` alone.
+6. `tinqs push` (LFS).
+
+## Verify
+
+On a Windows `ariki-game` checkout: run the `update-engine` skill, `game.sh run`, host a world, then
+`POST /command {"command":"env","key":"staticshadow","value":"on"}` — the log must NOT print
+`[STATIC-SHADOW] engine without the cache`, and `GET /perf` must show `staticShadow` with `enabled: true`.
+Terrain renders, animals animate, 0 `Wrapper class not found`.

+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).
