# Test data

`golden/` and `bgfx-reference/` contain historical reference screenshots. `assets.list` and `assets-good.txt` list asset samples; `m2-numeric.json` records Granny oracle comparisons.

Build the asset tools without a UI engine:

```sh
cmake -S . -B build-tools -DMT_BUILD_TOOLS=ON
cmake --build build-tools -j8
```

The active 40250 port tests run through `script/port_gate.sh macos`. The native SDL/Vulkan client has its own acceptance runner, `script/native_mac_acceptance.mjs`.
