name: baseline-equivalence-stimuli
description: >
  Stimulus library for the baseline-equivalence suite. Forty prompts across
  eight categories: factual-recall, code-qa, tool-trigger, instruction-bleed,
  customization-boundary, multi-turn, ambiguous-spec, and scope-redirect.
  This file is the authoritative human-readable source; baseline/eval.yaml
  and customized/eval.yaml inline equivalent stimulus entries with graders
  attached per Vally 0.4.0 schema. Contributor workflow: edit this file
  first, then mirror name/prompt/tags into the two eval.yaml files.

  Explicit non-goals: no safety, refusal, or jailbreak prompts. Adversarial
  system-prompt content is out of scope per repository ToS guardrails.
