Halluc-Complexity-Recursive-Memo

The model receives the prompt (and optional system message). The run uses scorer rubric_json_metrics with the JSON configuration below. Pass/fail and partial credit are determined entirely by that scorer against the model output; no human grading.

Return JSON only with keys answer, supported_facts, uncertainty. A recursion computes fib(n) with memoization. State expected time complexity and avoid claiming exponential after memoization.
