API and persisted records use PowerOnModel system fields: - sysCreatedAt, sysCreatedBy, sysModifiedAt, sysModifiedBy Removed legacy JSON/DB field names: - _createdAt, _createdBy, _modifiedAt, _modifiedBy Frontend (frontend_nyla) and gateway call sites were updated accordingly. Database: - Bootstrap runs idempotent backfill (_migrateSystemFieldColumns) from old underscore columns and selected business duplicates into sys* where sys* IS NULL. - Re-run app bootstrap against each PostgreSQL database after deploy. - Optional: DROP INDEX IF EXISTS "idx_invitation_createdby" if an old index remains; new index: idx_invitation_syscreatedby on Invitation(sysCreatedBy). Tests: - RBAC integration tests aligned with current GROUP mandate filter and UserMandate-based UserConnection GROUP clause; buildRbacWhereClause(..., mandateId=...) must be passed explicitly (same as production request context).
