mapping-builder

Build a reviewed crosswalk (RequirementMappingSet YAML library + review xlsx/csv) between two CISO Assistant framework YAML files using Claude itself as the reasoning engine. Zero infrastructure — stdlib + pyyaml only, no embedders, no LM Studio, no Qdrant. Use when the user asks to map / crosswalk / generate a mapping between two frameworks (e.g. ccb-cff-2023-03-01.yaml ↔ cyfun2025.yaml), wants to contribute a community mapping to backend/library/libraries/, or says things like "build a mapping between framework X and Y", "create a crosswalk YAML", "generate requirement_mapping_set". Output matches the schema in backend/library/libraries/mapping-*.yaml exactly so the result is PR-able.
