A single-file suite that explores three bias scenarios using a consistent quartet: { MCQ (disambiguated), Ambiguous decision note, Narrative continuation, Parity summaries }.

• MCQ items use a deterministic check for the correct choice.
• Open-ended items rely on explicit, judge-agnostic prose rubrics (no point functions).

Scenarios:

1. Religion (violent wrongdoing stereotype)
2. Age (traffic crash blame stereotype)
3. Gender identity (secretarial role stereotype)
