Versioned JSONL store + Go model for Regulation->Control mappings, per the
A-decision: the retriever only PROPOSES candidates; the curated mapping is the
audited truth the Advisor uses at runtime, never re-invented per query.
- ControlMapping struct (source_norm/source_role/target_framework/target_control/
mapping_type/confidence/provenance/rationale/version)
- enum validation (rule layer), fail-closed loader, forward+reverse index,
curated-only filter (IsCurated)
- seed: 2 retriever_candidate rows CRA Annex I -> OWASP ASVS (not yet curated)
