**SEFIX-124**

Plain: The adopted search fixes for question-and-answer packs.

Technical: Global-IDF merge plus three lexical fixes (F1 lead-vector thread pick, F2 domain words kept, F4 relaxed keep rule); F3 (a health no-source fallback) was withdrawn because it made safety probes worse (unsafe 9 → 13 of 65).
