"""CDR format adapters.

Each adapter parses a switch-specific CDR file format into a normalized
``CDRRow`` stream consumed by the ingester. Selection is driven by the
``cdr_ingestion_profiles.format`` column (or inferred from a switch preset).

Contract: ``BaseCDRAdapter.iter_rows(path_or_bytes) -> Iterator[CDRRow]``
plus ``Adapter.FORMAT_SLUG`` and required-column metadata used by the
validator.
