Enum Selector 

pub enum Selector {
    Dotted(Vec<String>),
    JsonPath(Box<JpQuery>),
}

What a field rule’s field string selects out of a document.

A field starting with $ is compiled as RFC 9535 JSONPath; anything else keeps the original dotted-path behaviour. RFC 9535 requires a query to start with $ and no dotted path does, so the discrimination is unambiguous and every manifest written before JSONPath existed still parses the same way.

Variants

Dotted(Vec<String>)

Pre-split dotted path; numeric segments index arrays. Empty = whole document.

JsonPath(Box<JpQuery>)

Compiled RFC 9535 query. Compiled once here so a document loop never reparses it. Boxed because JpQuery is much larger than a Vec, and a FieldRule is cloned per part rule.
