Probiotics for mood: C → C
Source correction by Claude (b2 garbage-source correction): replaced an off-topic search-fallback source (published before the pump's topicality gate existed) with a real, on-topic paper (PMID 31004628, "Prebiotics and probiotics for depression and anxiety: A systematic review and meta-analysis of controlled clinical trials."). Verdict/grade unchanged; only the provenance was wrong.
