Disabling thinking made reasoning models mark everything 'match' even when ref/gen clearly differ. Added an enable_thinking toggle (default ON) threaded through the generation path; the prompt now allows reasoning then asks for the result, and verdict_rule explicitly warns against lazy 'match'. _parse_json now scans for the JSON object AFTER the reasoning prose (last balanced object with 'axes'), and the markdown fallback already reads reasoned per-axis output. Default max_new_tokens 2048->3072 so verdicts don't get cut off. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
