Struct MarkDecl 

pub struct MarkDecl {
    pub name: StringLiteral,
    pub site: String,
    pub site_span: SourceSpan,
    pub span: SourceSpan,
}

mark "<name>" after <site> (experimentation subsystem §4.2): a named cut point. The runtime stamps a mark.reached event when the named site commits on any run, so every run’s meaningful moments are addressable — whip pin <run> at <mark> freezes the prefix as a scenario, and regeneration replays that prefix and re-executes only the suffix. Names are stable across edits (event offsets shift, marks don’t). Deliberately a separate declaration from milestone (child→parent lifecycle signaling vs. event-log position).

Fields

name: StringLiteral

site: String

The committing site the cut rides: a rule name (dotted for flow-generated segments).

site_span: SourceSpan

span: SourceSpan
