All hidden tests passed
42 of 42, including the three boundary cases.
Performance not scored
This ran on a dev-grade node, so a timing comparison against the reference hardware would be dishonest.
Coverage below the minimum
71% against a required 80%. The test-quality axis zeroes when either gate fails — that rule is what stops `assert False` from scoring full marks.
Wrong answer on a hidden test
Nothing downstream of correctness is scored.
