Provided Methods

fn identity_tokens( &self, _id: NodeId, _data: &dyn DataAccess, ) -> BinocResult<Option<Vec<IdentityToken>>>

Partition-identity tokens for a node (CFM-72), or None when no registered IdentityExtractor matches an artifact the node carries.

The engine owns the dispatch: it tries each registered extractor’s format against the node’s artifacts and runs the first match. The rule stays format-ignorant — it sees only opaque, globally-comparable tokens — so the same partition rule serves every partition-capable format. Computed JIT over whatever node the caller asks about (intended: the unmatched residue); never stored.
