Contig aliases choose an arbitrary reference target · case 02
Contig aliases choose an arbitrary reference target.
Case contract
Names identify canonical contigs; aliases may collide. Exact canonical match wins; ambiguous or absent aliases return None.
Why this case matters
An abstract offline coordinate model isolates this software mapping defect; it does not model biological interpretation.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| ambiguous alias | "contig2" | null | Failed |
