BOM Line

One purchasable item on the single Design BOM (ADR-0131). Imported lines are one per type (project|type) or one per type and space (project|type|space) and carry that type's product code. Authored lines are inserted (project|authored|<domain_id>) and are not re-aggregated. Postgres pdg_bom_line; Construction project_bom_lines is the projection. Rematerialize orphans only imported lines. An authored line is removed by the delete command.
