- Change type: Changed
- Affected operations: parcel assignment, pending-quote cancellation, parcel destination handling
- Description: Parcel assignment became polymorphic; pending quotes gained cancellation with validation for ineligible transitions; parcel destinations lock once set.
- Integration impact: Cancellation attempts on ineligible quotes now fail with explicit errors instead of succeeding silently.
- Migration: Handle cancellation error responses; no data migration needed.
