Circular sequence windows miss the origin-spanning start · case 04

Circular sequence windows miss the origin-spanning start.

Member previewVariant 4 · 3 implementations · 6 checks per implementation

Case contract

For nonempty ACGT string and 1<=k<=length, return exactly length windows of size k wrapping around origin, in start-index order. Empty returns [].

Why this case matters

An offline abstract sequence-data model; useful for testing representation invariants without biological inference.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
