@@ -371,7 +369,7 @@ Shader source semantics:
- later layers receive `gVideoInput = original input` and `gLayerInput = previous layer`.
- named intermediate pass inputs inside a multipass layer are still routed through the selected pass-source slot; layer stacking should use `gLayerInput`.
The `/api/state` shader list uses the same support rules as runtime shader compilation and reports only packages this app can run today. Unsupported manifest feature sets such as temporal, feedback, texture-backed, font-backed, or text-parameter shaders are hidden from the control UI for now.
The `/api/state` shader list uses the same support rules as runtime shader compilation and reports only packages this app can run today. Unsupported manifest feature sets such as temporal, feedback, and texture-backed shaders are hidden from the control UI for now.
Runtime shaders are exposed through `RuntimeLayerModel` as display layers with manifest parameter definitions, current parameter values, build status, and render-ready artifacts. POST controls mutate this app-owned model and may start background shader builds when the selected shader changes.
