Polynomial decay scales progress before subtracting from one · case 04
Polynomial decay scales progress before subtracting from one.
Case contract
Return base*max(0,1-step/total)**power for nonnegative step.
Why this case matters
A deterministic scalar schedule makes step-to-rate mapping explicit for a small training loop.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| square midpoint | 0 | 4 | Failed |
