Strand canonicalization compares a word with its reversal · case 05
Strand canonicalization compares a word with its reversal.
Case contract
Return lexicographic minimum of an ACGT string and its reverse-complement using A:T,C:G. Empty maps to empty.
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 | "GTTTTT" | "CAAAAA" | Failed |
