Struct LoadReport 

pub struct LoadReport {
    pub presets: Vec<Preset>,
    pub errors: Vec<(PathBuf, PresetError)>,
    pub warnings: Vec<(PathBuf, String)>,
}

The outcome of loading a preset directory: the presets that compiled, in filename order, plus the files that failed and the non-fatal problems found in the ones that succeeded (so the caller can surface both).

Fields

presets: Vec<Preset>

Successfully compiled presets, sorted by filename for a stable cycle.

errors: Vec<(PathBuf, PresetError)>

(path, error) for each .toml that failed to read or compile.

warnings: Vec<(PathBuf, String)>

(path, warning) for each non-fatal problem in a preset that did load — today, a binding naming a parameter its system does not consume (ADR-0020). Surfacing these is what stops a typo from failing silently; the preset itself is in presets and renders normally.
