+- [x] 4.3 (P) Confirm no regression to existing reconciliation and the rest of the snapshot format
   - Run the existing replay-based reconciliation test coverage and the full existing test suite unchanged; confirm they all still pass exactly as before this feature.
   - Confirm no other previously-supported snapshot field's save/load behavior changed.
   - Observable completion: a full test run shows zero new failures and zero behavior change outside the allocation/scheduling-representation fields this feature touches.
