Package bench is the measurement harness: a golden-ranking scorer, a ladder of pinned public Go corpora, per-stage performance benchmarks over them, and the generator behind the reports in examples/.

Package culture models the repository's local conceptual practice from counts alone: which concepts, roles, and calls co-occur beyond chance (ecology), and how each concept is normally realized here (prototypes and typicality).

Package fingerprint builds deterministic static summaries of Go function bodies and scores how similar two of them are.

Package ontology is Doppel's formal vocabulary: the entity kinds, typed relations, intent concepts and structural roles the rest of the pipeline reasons about, declared once with definitions and machine-checkable axioms.

Package retriever generates candidate pairs for the expensive structural comparison stage.

Package snapshot captures one complete doppel analysis run as plain data, so that two runs can be compared.
