Merkle tree diffs produce sorted leaf indices that map directly to key ranges when the tree is built with key-sorted input, enabling anti-entropy repair that transfers only divergent key ranges rather than full dataset comparisons.
Sorted key input + sorted index output = direct mapping from diff results to key ranges needing repair
