# 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** (`d4940046`) — `a967d12b` (parallel draw-list replay + recording) plus the parallel-replay command-pool reset (VUID-00050 fix) | built-in module | ✅ yes (`GodotSharp/`) |
| `engine/windows-x64/`  | **4.7.2** (`a967d12bf`) — same hash as macos-arm64: `e64890fd` plus parallel draw-list replay + recording (both default off; oracle 10/10, one VUID finding recorded); `template_release` here is still the `1e7be28b` tree | built-in module | ✅ yes (`GodotSharp/`) |

Mac is engine `d4940046` as of 2026-10-19 (`--version` `4.7.2.stable.mono.custom_build.d49400463`): `a967d12b` plus a per-frame reset of the parallel-replay secondary command pools (fixes VUID-vkBeginCommandBuffer-00050). `a967d12b` is `e64890fd` plus parallel draw-list replay (Vulkan only) and parallel draw-list recording (every driver), both engine-default off and turned on by the game; GodotSharp regenerated; oracle `parallel_draw_replay` Vulkan 10/10, Metal 5/5 (`engine/.agents/wiki/parallel-draw-replay.md`). **Windows is also engine `a967d12bf` as of 2026-10-19** — Forge ran the engine-side tests before publishing (engine `.agents/wiki/parallel-draw-replay.md` § Windows (Forge)): replay+record oracle Vulkan with validation **10/10 exit 0** but **10× VUID-vkBeginCommandBuffer-00050** in the first parallel state (secondary command buffers re-begun from pools without `RESET_COMMAND_BUFFER_BIT`; feature-off control = 0 VUIDs; NVIDIA tolerates it, MoltenVK never flagged — engine-owner fix owed); `draw_indirect_count` d3d12 with the newly installed debug layer **22/0 + expected SKIP line** (the old 22/2 was the no-layer run where base-instance ran instead of skipping); `multimesh_cull_pool` d3d12 **4524/4524** — parity with Mac. Vulkan SDK + Graphics Tools are now installed on Forge, closing the "--gpu-validation owed" notes. Still owed (same wiki section): the VUID-00050 fix + a `--gpu-validation` soak, tests=yes unit suites, crash checklist. Before this, Mac was engine `e64890fd` as of 2026-10-18: `4fde0e94` plus the Apple autorelease-drain fix (Mach-port leak, flat at ~640 ports now) and the G4 mergeable-draw census. Underneath, `4fde0e94` added G2 pooled GPU cull (`env gpucull pool`), fixed shadow LOD band (`env gpucull shadowband`) and `STATIC_SHADOW_AT_REST` (`env gpucull staticrest`; the game's `tree_wind.gdshader` uses it); all default off. 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`).

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