6. C++

The C++ domain class is decomposed into nested sub-structs (the C1202 pattern from PRs #1047/#1071/#1075/#1083/#1085): the implicit scaffolding columns (version, tenant_id, workspace_id, the primary key) and the columns marked :group: identity above fold into an instrument_identity identity; member (see the ores.trading.instrument_identity field-group model), the implicit audit columns fold into an ores::dq::domain::audit_record audit; member (see the ores.dq.audit_record field-group model), and the remaining columns stay flat in between. The SQL schema, DB entity and column lists are unaffected — only the domain class and the mapper's domain-side accesses nest. The entity templates consume these annotations; domain and repository profiles regenerate correctly.
