Use these records without custom-field extensions
Context
Custom fields require an explicit per-entity product declaration.
Decision
Retain these Commerce records without custom fields under the cited opt-in architecture ruling.
Alternatives Considered
Add custom fields to warehouse or shipment registrations. The registration contains no approved declaration for shipment or warehouse custom fields.
Consequences
Additional schema or custom-field needs require a product decision. Existing screens use their built components and schemas.
