 ### Fixes
 
+- Models/MiniMax: stop advertising removed `MiniMax-M2.5-Lightning` in built-in provider catalogs, onboarding metadata, and docs; keep the supported fast-tier model as `MiniMax-M2.5-highspeed`.
 - Security/Config: fail closed when `loadConfig()` hits validation or read errors so invalid configs cannot silently fall back to permissive runtime defaults. (#9040) Thanks @joetomasone.
 - Memory/Hybrid search: preserve negative FTS5 BM25 relevance ordering in `bm25RankToScore()` so stronger keyword matches rank above weaker ones instead of collapsing or reversing scores. (#33757) Thanks @lsdcc01.
 - LINE/`requireMention` group gating: align inbound and reply-stage LINE group policy resolution across raw, `group:`, and `room:` keys (including account-scoped group config), preserve plugin-backed reply-stage fallback behavior, and add regression coverage for prefixed-only group/room config plus reply-stage policy resolution. (#35847) Thanks @kirisame-wang.
