Read-only layer (service + thin route + tests) that returns the controls
mapped to a use-case/topic, ranked by a deterministic precision proxy
(is_primary + mapping confidence + registry keyword relevance) over the
existing mc_use_case_mappings seed. No schema change.
Shared handoff point: the document specialist agents AND the CRA
finding-mapper draw from this one controls index instead of separate
retrievals.
