 ### Fixes
 
+- Discord/subagents: pass runtime config into thread-bound native subagent binding and require it at the helper boundary so Discord channel resolution keeps account-aware config. Fixes #71054. (#70945) Thanks @jai.
 - Agents/failover: stop body-less HTTP 400/422 proxy failures from defaulting to `"format"` classification, so embedded retries surface the opaque provider failure instead of falling into a compaction loop. Fixes #66462. (#67024) Thanks @altaywtf and @HongzhuLiu.
 - Plugins/loader: use cached discovery-mode snapshot loads for read-only plugin capability lookups, keep snapshot caches isolated from active Gateway registries, and make same-plugin channel/HTTP route re-registration idempotent so repeated snapshot or hot-reload paths no longer rerun full plugin side effects or accumulate duplicate surfaces. Fixes #51781, #52031, #54181, and #57514. Thanks @livingghost, @okuyam2y, @ShionEria, and @bbshih.
