Select an answer to reveal the explanation.
Short Explanation
Stall names vanish on rainy Saturdays. That missingness plot is a data-quality finding for prep, not proof the later model underfit, and not a Guardrails fairness rule. Fill, flag, or stratify those rows before anyone trains.
Full Explanation
Visualizing missing values and reading systematic gaps is prep work. Stall names that vanish on rainy Saturdays are a data-quality finding, not an overfitting diagnosis and not a fairness principle. Fill, flag, or stratify those rows before anyone trains. Domain 4 owns the missingness view.
