# tinqs/builds

Build artifacts for the Tinqs stack — engine editor binaries (+ their GodotSharp C# bindings).
**Binaries and GodotSharp are stored via Git LFS** (see `.gitattributes`). Source lives in
`tinqs/engine`, `tinqs/ariki-game`, `tinqs/ariki-sim`. See `manifest.json` for exact versions.

> **Use `tinqs pull` / `tinqs push`, never raw git** — these are LFS-heavy.

## Installing / updating the engine

**Don't copy files by hand — run the `update-engine` skill (it lives in the game repo, which everyone has):**
[tinqs.com/tinqs/ariki-game · .agents/skills/update-engine](https://tinqs.com/tinqs/ariki-game/src/branch/main/.agents/skills/update-engine/SKILL.md).
Hand it to your agent; it `tinqs pull`s ariki-game + builds, installs the binary + GodotSharp into
`../engine/bin/`, wipes stale caches, and verifies. Covers macOS + Windows.

## ⚠️ The one rule: binary + GodotSharp are a MATCHED PAIR

Each engine binary ships with a `GodotSharp/` folder (Godot's C# bindings) **generated from that
exact engine build**. You must install them **together** and replace any old `GodotSharp`.

- The engine does **NOT** regenerate GodotSharp at runtime. If it's missing you get a
  **`.NET assemblies not found`** dialog pointing at `engine/bin/GodotSharp/Api/Debug`.
- A **stale** GodotSharp (from an older engine) against a newer binary throws
  **`Wrapper class not found for type: Terrain3D`** → terrain renders as water, animals don't animate.

This matters now because **Terrain3D and `agent_skinned` are native engine modules** (no separate
`addons/terrain_3d` GDExtension `.framework`). Built-in module classes need their wrappers baked
into GodotSharp, so GodotSharp had to be regenerated — and must ship here alongside the binary.

## Current contents

| Platform | Engine | Terrain3D | GodotSharp shipped? |
|---|---|---|---|
| `engine/macos-arm64/` | **4.7.2** (`73d20a40`) — `d4940046` plus the #250 parallel-recording nesting fix and the Texture2DRD bind-race fix | built-in module | ✅ yes (`GodotSharp/`) |
| `engine/windows-x64/`  | **4.7.2** (`73d20a40b`) — same hash as macos-arm64: parallel replay+recording (game ships both ON) + VUID-00050 pool reset + the #250 recording-nest FATAL fix + the Texture2DRD bind-race fix (milky ocean); `template_release` here is still the `1e7be28b` tree | built-in module | ✅ yes (`GodotSharp/`) |

Mac is engine `73d20a40` as of 2026-10-19 (`--version` `4.7.2.stable.mono.custom_build.73d20a40b`): `d4940046` plus `219b914c` (#250, parallel draw-list sub-recordings nest; Windows Ultra-bench FATAL) and `73d20a40` (RD texture wrappers allocate their RS texture before the render-thread bind, fixing the milky ocean under the separate render thread); GodotSharp regenerated, API unchanged. **Windows is also engine `73d20a40b` as of 2026-10-19** — Forge fast-published on the owner's request after GodotSharp regen (oracle + headless smoke on this exact hash still owed; both fixes sit in the engine's own oracle coverage). Before this, Windows `d49400463` verified the VUID-00050 pool-reset fix with a validated oracle run (10/10, zero VUIDs) and carried the parallel features' fps-lane results (no regression, rGPU 8.1→6.8 ms, soak + eye check pass, game ships both ON); `draw_indirect_count` d3d12 22/0 with debug layer, `multimesh_cull_pool` d3d12 4524/4524 (pooled-cull gate met); Vulkan SDK + Graphics Tools installed on Forge. Still owed on Windows: oracle on `73d20a40b`, a `--gpu-validation` in-game soak, tests=yes unit suites, crash checklist. Underneath: `e64890fd` (Apple autorelease-drain + G4 census) on `4fde0e94` (G2 pooled cull, fixed shadow band, `STATIC_SHADOW_AT_REST`) on 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`).

Long-term: CI (Gitea Actions) builds on push and publishes here / to S3 —
`docs/ai/plans/build-pipeline-architecture-2026-06-07.md`.
