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`.

-name: update-engine
-description: Install/update the local Tinqs engine (binary + GodotSharp C# bindings) from this builds repo so ariki-game runs on the current engine. Use when an engine update is announced, when setting up a new machine, or when the game shows ".NET assemblies not found" or "Wrapper class not found for type: Terrain3D" (terrain is water / animals don't animate). Covers macOS (arm64) and Windows (x64).
----
-
-# Update the Tinqs engine from `builds`
-
-**Only Ozan edits the engine source.** Everyone else installs the prebuilt engine from this
-repo into `../engine/bin/`, which is where `ariki-game` looks for it.
-
-## ⚠️ Read this first — binary + GodotSharp are a MATCHED PAIR
-
-The engine binary and its `GodotSharp/` folder (Godot's C# bindings) are **both generated from the
-same engine source** and must be installed **together**. The binary does **not** regenerate
-`GodotSharp` — it must sit next to the binary on disk. Mismatch symptoms:
-
-| Symptom | Cause |
-|---|---|
-| `.NET assemblies not found` dialog (looks for `engine/bin/GodotSharp/Api/Debug`) | no `GodotSharp` present |
-| `Wrapper class not found for type: Terrain3D` / `MultiSkinnedMeshInstance3D` — terrain renders as water, animals don't animate | **stale** `GodotSharp` from an older engine that predates the built-in Terrain3D / agent_skinned modules |
-
-So: always **replace `GodotSharp` wholesale** when you take a new binary, and clear the game's C#
-cache so it rebuilds against the new bindings.
-
-## Assumed layout
-
-```
-tinqs-ltd/
-  ariki-game/    ← the game  (looks for ../engine/bin/…)
-  engine/bin/    ← install target: binary + GodotSharp live here
-  builds/        ← this repo (prebuilt engine)
-```
-Adjust paths below if your checkout differs.
-
-## 1. Pull the latest build
-
-```bash
-cd <…>/builds
-tinqs pull          # never `git pull` — tinqs handles LFS (the binary + GodotSharp are LFS)
-```
-Check `builds/manifest.json` for the current version/commit per platform.
-
-## 2a. Install — macOS (arm64)
-
-```bash
-BUILDS="<…>/builds"; ENGINE="<…>/engine/bin"; GAME="<…>/ariki-game"
-mkdir -p "$ENGINE"
-# 1) binary
-cp "$BUILDS/engine/macos-arm64/tinqs.macos.editor.arm64.mono" "$ENGINE/"
-chmod +x "$ENGINE/tinqs.macos.editor.arm64.mono"
-# 2) GodotSharp — REPLACE wholesale (matched pair)
-rm -rf "$ENGINE/GodotSharp"
-cp -R "$BUILDS/engine/macos-arm64/GodotSharp" "$ENGINE/GodotSharp"
-# 3) clear the game's stale C# cache
-rm -rf "$GAME/.godot/mono"
-```
-
-## 2b. Install — Windows (x64), PowerShell
-
-```powershell
-$builds="<…>\builds"; $engine="<…>\engine\bin"; $game="<…>\ariki-game"
-New-Item -ItemType Directory -Force -Path $engine | Out-Null
-# 1) binaries
-Copy-Item "$builds\engine\windows-x64\tinqs.windows.editor.x86_64.mono.exe" $engine -Force
-Copy-Item "$builds\engine\windows-x64\tinqs.windows.editor.x86_64.mono.console.exe" $engine -Force
-# 2) GodotSharp — REPLACE wholesale (matched pair)
-Remove-Item -Recurse -Force "$engine\GodotSharp" -ErrorAction SilentlyContinue
-Copy-Item -Recurse "$builds\engine\windows-x64\GodotSharp" "$engine\GodotSharp"
-# 3) clear the game's stale C# cache
-Remove-Item -Recurse -Force "$game\.godot\mono" -ErrorAction SilentlyContinue
-```
-
-## 3. Verify
-
-```bash
-"$ENGINE/tinqs.macos.editor.arm64.mono" --version          # matches manifest.json
-ls "$ENGINE/GodotSharp/Api/Debug/GodotSharp.dll"            # MUST exist
-```
-Then run the game (`cd ariki-game && bash tools/game.sh run`). Healthy = terrain renders, animals
-animate, log shows **0** `Wrapper class not found` and no `.NET assemblies not found` dialog.
-
-## Notes
-
-- **GodotSharp must be present in this repo for the copy to work.** If `builds/engine/<platform>/GodotSharp`
-  is missing, the build owner needs to add it (it ships *with* the binary — see `manifest.json`).
-- Don't mix a new binary with an old `GodotSharp`. Always replace both, together.
-- Terrain3D and the skinned-animation classes are **built into the engine binary** now (no separate
-  `addons/terrain_3d` GDExtension `.framework`). If you still have `addons/terrain_3d/terrain.gdextension`
-  or the macOS `.framework`, remove them — they conflict with the built-in module.
