Reference deletions fail to advance alignment position · case 03

Reference deletions fail to advance alignment position.

Member previewVariant 3 · 3 implementations · 6 checks per implementation

Case contract

Map a zero-based query base through M/I/D operation lengths; inserted and absent query bases 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
