Continued fraction convergents: denominator seeds · case 04
The exact continued fraction convergents result violates the stated contract at denominator seeds.
Case contract
Input nonempty coefficients with positive terms after first; return every convergent as [numerator,positive denominator].
Why this case matters
Exact discrete arithmetic with observable algorithmic state; no floating point approximation is used.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| explicit oracle 0 | [[1, 1], [2, 2]] | [[1, 1], [2, 1]] | Failed |
