Pell positive solutions: requested solution count · case 02
The exact pell positive solutions result violates the stated contract at requested solution count.
Case contract
Input [D,u,v,k], known positive fundamental solution u^2-D*v^2=1, k>=0; return first k positive solutions.
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 | [[3, 2], [17, 12]] | [[3, 2]] | Failed |
