  2. Phase 4 features are optional enhancements - These are "nice to have" features that don't block core functionality.

  3. Documentation should be updated - The ORDER_MANAGEMENT_LOGIC.md file should be updated to reflect that Issues 1-10 are now implemented, and Phase 4 features are marked as "Future Enhancements".

  4. No breaking changes - All implementations are backward compatible.
