 ### Changes
 
+- Docs/Subagents: make thread-bound session guidance channel-first instead of Discord-specific, and list thread-supporting channels explicitly. (#23589) Thanks @osolmaz.
 - Channels/Config: unify channel preview streaming config handling with a shared resolver and canonical migration path.
 - Discord/Allowlist: canonicalize resolved Discord allowlist names to IDs and split resolution flow for clearer fail-closed behavior.
 - Memory/FTS: add Korean stop-word filtering and particle-aware keyword extraction (including mixed Korean/English stems) for query expansion in FTS-only search mode. (#18899) Thanks @ruypang.
