Struct SupplementDescriptor 

pub struct SupplementDescriptor {
    pub summary: &'static str,
    pub schema: Option<&'static str>,
    pub diagnostic_codes: &'static [&'static str],
    pub requires: &'static [&'static str],
}

Self-reported metadata about what a supplement validates and declares — colocated in the same module as the parse_and_validate_*/validate() logic that actually produces diagnostic_codes, so a change to one is a scroll away from the other, not a separate hand-maintained copy in a different crate. etdl capabilities/etdl supplement list read this generically (ExtensionRegistry::list/lookup + descriptor()) instead of each caller hard-coding a per-supplement summary — see crate::performance’s descriptor() for the reference shape every built-in supplement follows.

Fields

summary: &'static str

One-line human summary of what this supplement validates/declares. Empty (the default) for an extension that doesn’t override EtdlExtension::descriptor — e.g. a dynamically loaded .wasm plugin, whose wire ABI (docs/reference/supplement-plugins.md) carries no description field to report here.

schema: Option<&'static str>

The schema/version string this supplement’s x-* field is versioned against (e.g. "etdl.performance/1.0"), if it has one distinct from EtdlExtension::version().

diagnostic_codes: &'static [&'static str]

Every diagnostic code this supplement’s own validation can produce.

requires: &'static [&'static str]

Other supplement ids this one has a real dependency on, if any (e.g. etdl.security on etdl.tree-event — see crate::security’s module docs for what “dependency” means in practice here).
