Struct Metadata 

pub struct Metadata {
    pub stage_id: String,
    pub sig_id: String,
    pub name: String,
    pub published_at: u64,
    pub note: Option<String>,
    pub signature: Option<Signature>,
}

Per-implementation metadata (<StageId>.metadata.json).

Fields

stage_id: String

sig_id: String

name: String

Human-friendly name (e.g. “factorial”). Lives here, not in the implementation hash, so renames don’t change StageId.

published_at: u64

note: Option<String>

Free-form notes (e.g. “fixes overflow on n>20”).

signature: Option<Signature>

Optional Ed25519 signature over the UTF-8 bytes of stage_id (#227). Set on publish when the caller provides a signing key; consumers verify via lex_vcs::verify_stage_id. Absence means “unsigned” — policy decides whether to accept it.
