 ### Fixes
 
+- Discord/Threading: recover missing thread parent IDs by refetching thread metadata before resolving parent channel context. (#24897) Thanks @z-x-yang.
 - Web UI/i18n: load and hydrate saved locale translations during startup so non-English sessions apply immediately without manual toggling. (#24795) Thanks @chilu18.
 - Plugins/Config schema: support legacy plugin schemas without `toJSONSchema()` by falling back to permissive object schema generation. (#24933) Thanks @pandego.
 - Cron/Isolated sessions: use full prompt mode for isolated cron runs so skills/extensions are available during cron execution. (#24944)
