# Runtime Files

This directory is used by the native host for local runtime output.

Tracked files:

- `templates/`: source templates used to generate shader runtime code.

Packaged documentation:

- `../docs/openapi.yaml`: OpenAPI/Swagger spec for the local control API.
- `../docs/OSC_CONTROL.md`: OSC address and value reference.
- `http://127.0.0.1:<serverPort>/docs`: Swagger UI page served by the native control server.

Generated files:

- `shader_cache/active_shader_wrapper.slang`: generated Slang wrapper for the most recently compiled shader pass.
- `shader_cache/active_shader.raw.frag`: raw GLSL emitted by `slangc` for the most recently compiled pass.
- `shader_cache/active_shader.frag`: patched GLSL consumed by the OpenGL path for the most recently compiled pass.
- `runtime_state.json`: autosaved latest layer stack, layer order, bypass state, shader assignments, and parameter values. The host reloads this file on startup.
- `stack_presets/*.json`: user-saved layer stack presets.
- `screenshots/*.png`: screenshots captured from the final output render target through the control UI/API.

Git policy:

- Runtime cache/state/preset output is ignored by default.
- Template files are source files and should stay tracked.
- If a project wants shared stack presets, move selected preset JSON files into a tracked fixtures or presets directory intentionally rather than committing the whole runtime output tree.
