Description copied from class: Filter

Tests whether a record passes this filter.

Contract for subclasses (see also docs/authoring/Filter.md):

• Return true to keep the record.
• Return false to discard the record (routed to a discard writer if the host FilteringReader is configured with one).
• Must be a pure decision — do not mutate the record here.
• Throw DataException only for unrecoverable filter failures; for ordinary "data fails predicate" cases, return false.
