AshR2RML.Parity (AshR2RML v26.8.22)

Deterministic semantic-result comparator for side-by-side cutover evidence.

Query execution is intentionally outside this module. Callers execute the admitted SQL/SPARQL/Cypher queries, then pass their observed rows here. The comparator normalizes result multisets and emits a stable receipt that can be attached to AshR2RML.CompilationReceipt.
