Rational row reduction: pivot row cursor · case 02
The exact rational row reduction result violates the stated contract at pivot row cursor.
Case contract
Input nonempty rectangular integer matrix; return RREF with each rational entry [p,q].
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 | [[[2, 1], [1, 1]]] | [[[1, 1], [1, 2]]] | Failed |
