 - Agents/Compaction: pass model metadata through the embedded runtime so safeguard summarization can run when `ctx.model` is unavailable, avoiding repeated `"Summary unavailable due to context limits"` fallback summaries. (#3479) Thanks @battman21, @hanxiao and @vincentkoc.
 - Providers/Groq: avoid classifying Groq TPM limit errors as context overflow so throttling paths no longer trigger overflow recovery logic. (#16176) Thanks @dddabtc.
 - Agents/Overflow: detect additional provider context-overflow error shapes (including `input length` + `max_tokens` exceed-context variants) so failures route through compaction/recovery paths instead of leaking raw provider errors to users. (#9951) Thanks @echoVic and @Glucksberg.
+- Agents/Overflow: add Chinese context-overflow pattern detection in `isContextOverflowError` so localized provider errors route through overflow recovery paths. (#22855) Thanks @Clawborn.
 - Agents/Compaction: cancel safeguard compaction when summary generation cannot run (missing model/API key or summarization failure), preserving history instead of truncating to fallback `"Summary unavailable"` text. (#10711) Thanks @DukeDeSouth and @vincentkoc.
 - Agents/Failover: treat HTTP 502/503/504 errors as failover-eligible transient timeouts so fallback chains can switch providers/models during upstream outages instead of retrying the same failing target. (#20999) Thanks @taw0002 and @vincentkoc.
