 - Agents/BTW: strip replayed tool blocks, hidden reasoning, and malformed image payloads from `/btw` side-question context so Bedrock no-tools side questions keep working after tool-use turns. (#64225) Thanks @ngutman.
 - Commands/btw: keep tool-less side questions from sending injected empty `tools` arrays on strict OpenAI-compatible providers, so `/btw` continues working after prior tool-call history. (#64219) Thanks @ngutman.
 - Agents/Bedrock: let `/btw` side questions use `auth: "aws-sdk"` without a static API key so Bedrock IAM and instance-role sessions stop failing before the side question runs. (#64218) Thanks @SnowSky1.
+- Agents/failover: detect llama.cpp slot context overflows as context-overflow errors so compaction can retry self-hosted OpenAI-compatible runs instead of surfacing the raw upstream 400. (#64196) Thanks @alexander-applyinnovations.
