Walkthrough

A single change in src/evo/deterministicmns.h modifies CDeterministicMNListDiff::Unserialize(Stream& s) to explicitly clear addedMNs before reading, with a comment indicating resetting all collections prior to deserialization. This aligns addedMNs with existing resets for updatedMNs and removedMns. The rest of the deserialization logic (reading addedMNs, updatedMNs, removedMns from the stream) remains unchanged. No exported/public signatures were altered.

543-544: Good defensive programming practice!

Adding addedMNs.clear() ensures consistent behavior with the other collections (updatedMNs and removedMns) and prevents potential issues with residual data from previous deserializations.
