-### CSM-018 — `@moduledoc false` Epidemic
-- **Files:** `lib/bds/i18n.ex`, `lib/bds/map_utils.ex`, `lib/bds/bounded_atoms.ex`, `lib/bds/document_fields.ex`, `lib/bds/import_definitions.ex`, `lib/bds/publishing.ex`, `lib/bds/settings.ex`, `lib/bds/templates.ex`, `lib/bds/ai.ex`, `lib/bds/mcp.ex`, `lib/bds/scripting/capabilities.ex`, `lib/bds/scripting/api_docs.ex`
-- **Fix:** Write `@moduledoc` descriptions for all public modules. Keep internal helpers documented or mark them `@moduledoc false` only if truly private.
