# WHY: implementation-directory membership is not presentation reachability;
# scanning core SQL, synchronization codecs, and catalogs confuses durable raw
# diagnostics/identifiers with renderer copy.
# CONTRACT: this reviewed allowlist contains every active renderer plus the two
# known presentation-producing helpers. A new renderer must be added here and
# defaults to failure as soon as it contains uncatalogued French copy.
# INVARIANT: database/sync/sync_history/catalog implementations are not UI-copy
# owners and cannot become implicit exceptions through this audit.
