Quality filtering separates scores from surviving bases · case 02
Quality filtering separates scores from surviving bases.
Case contract
Given sequence and same-length integer qualities, return [retained_string,retained_qualities] preserving pairs whose quality is >= cutoff.
Why this case matters
An offline abstract sequence-data model; useful for testing representation invariants without biological inference.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| variable threshold | ["CT", [1, 2, 3]] | ["CT", [2, 3]] | Failed |
