Brief
Report 3 error slices on holdout predictions with a fix proposal per slice.
Dataset
Holdout predictions + labels; error-slice template provided.
Starter guardrails (88)
- Template slots: slice definition -> size -> error rate vs base -> hypothesis -> fix.
- Slices must cover >= 5% of holdout each (no anecdote slices).
Deterministic checks
Slice rates recompute from predictions; sizes meet the 5% floor.
