Struct CriterionDescriptor 

pub struct CriterionDescriptor {
    pub key: &'static str,
    pub label: &'static str,
    pub help: &'static str,
    pub quantity: Option<&'static str>,
    pub kind: CriterionKind,
    pub severities: &'static [CategorySeverity],
}

Descriptor of one criterion in an engine’s criteria catalog (spec §7.2).

key is stable per engine: applications persist valuations against it, so renaming one is a compatibility break.

Fields

key: &'static str

Stable criterion identifier, unique within the engine.

label: &'static str

Human-facing name.

help: &'static str

One or two sentences on what the criterion judges.

quantity: Option<&'static str>

§5 quantity key — values are in the quantity’s SI display unit — or None for a dimensionless criterion.

kind: CriterionKind

Shape of the criterion’s value.

severities: &'static [CategorySeverity]

What each region between the cut points means, ascending — one more entry than the criterion has cuts (spec §7.2).

Empty for a criterion that is judged in reports but never drawn. The engine’s to state because compliance is rarely monotonic: service pressure is worst when low, acceptable in a middle and worth attention again when high, and nothing in the numbers says which end is which.
