 - Protocol/Swift model sync: regenerate pending node work Swift bindings after the landed `node.pending.*` schema additions so generated protocol artifacts are consistent again. (#41477) Thanks @mbelinky.
 - Discord/reply chunking: resolve the effective `maxLinesPerMessage` config across live reply paths and preserve `chunkMode` in the fast send path so long Discord replies no longer split unexpectedly at the default 17-line limit. (#40133) thanks @rbutera.
 - Logging/probe observations: suppress structured embedded and model-fallback probe warnings on the console without hiding error or fatal output. (#41338) thanks @altaywtf.
+- Agents/fallback: treat HTTP 499 responses as transient in both raw-text and structured failover paths so Anthropic-style client-closed overload responses trigger model fallback reliably. (#41468) thanks @zeroasterisk.
