acceptance_criteria_grader $0.001 per call

Deterministically grades a candidate text against a checklist of acceptance criteria. Each criterion specifies either a plain substring ('contains') or a regular expression ('pattern', JS regex, case-insensitive) to search for in the text, and whether it is required. Returns per-criterion pass/fail plus an overall score. Pure offline pattern matching, no LLM and no network calls.
