different-length fingerprints appear identical.
Case contract
Return Hamming distance for equal-length strings; return None for unequal lengths.
Why this case matters
This deterministic toy operation makes one dataset equivalence or representative rule explicit.
One recorded failure

| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| unequal suffix | 0 | null | Failed |
