- Retry provider-confirmed transport failures once before substantive content is emitted, preventing transient disconnects from failing chats or duplicating output.
- Classify retryability explicitly per provider while leaving HTTP status retries to SDKs, avoiding deterministic-error replays and retry amplification.
- Persist usage from failed attempts and add unit and integration coverage for classification, recovery, and single-message persistence.
- flag transport-level provider errors explicitly - retry once before substantive stream content and persist usage - cover provider classification and stream recovery behavior
- cover Anthropic Bedrock connection failures - recognize raw httpx stream failures alongside botocore errors - add provider classification coverage
