Mutation ReasoningThe new claim is textually identical to the historical source evidence from 2018 (claim_id: d9810506bca0fd6f). No semantic, lexical, or structural deviation exists — same subject (CTG), same starting point (urban sewage treatment), same role (backbone role), and same objective (concerted effort to protect the Yangtze River). The contextual reference to the CPC Central Committee and State Council mandate provides background but does not alter the claim itself; it reinforces rather than mutates it. Therefore, no mutation is present.
