/**
 * BUG-1056 (TASK-rectification-grounding-20260927 T2): the rectification
 * 「重试（重新生成）」 is gone. The rewrite was a blind `agent.generate` with no
 * question stripping, range sentence, number or word checks, persisted as is.
 * Ordinary consultation keeps its regenerate button. The database function
 * `regenerate_agentic_rectification_turn` is deliberately left in place
 * (AGENTS §7.6: code first, retire the function in a later round).
