Error-Analysis + Slice Writeup

# Submission: Error-Analysis + Slice Writeup ## 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. ## 100-pt rubric - Slice validity (definition + size): 25 - Rate-vs-base analysis: 25 - Hypotheses grounded in features: 20 - Fix proposals (actionable, scoped): 20 - Writeup clarity: 10
