Repeating radix fraction: remainder transition · case 05
The exact repeating radix fraction result violates the stated contract at remainder transition.
Case contract
Input [p,q,base], 0<=p<q, q>0, base2..10; return nonrepeating digit list and repeating digit list. Bounds: 2<=q<=19 and 2<=base<=8.
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.
