 ### Fixes
 
+- Failover/error classification: treat HTTP `529` (provider overloaded, common with Anthropic-compatible APIs) as `rate_limit` so model failover can engage instead of misclassifying the error path. (#31854) Thanks @bugkill3r.
 - Voice-call/webhook routing: require exact webhook path matches (instead of prefix matches) so lookalike paths cannot reach provider verification/dispatch logic. (#31930) Thanks @afurm.
 - Web UI/config form: support SecretInput string-or-secret-ref unions in map `additionalProperties`, so provider API key fields stay editable instead of being marked unsupported. (#31866) Thanks @ningding97.
 - Slack/Bolt startup compatibility: remove invalid `message.channels` and `message.groups` event registrations so Slack providers no longer crash on startup with Bolt 4.6+; channel/group traffic continues through the unified `message` handler (`channel_type`). (#32033) Thanks @mahopan.
