1.0.0b5 (2026-04-22)

All HTTP responses now include an x-request-id header for request correlation. Value is resolved in priority order: OTEL trace ID → incoming x-request-id header → new UUID.
Error responses (4xx/5xx) with a JSON error body are automatically enriched with error.additionalInfo.request_id matching the x-request-id response header, enabling client-side error correlation.
Persistence failure resilience — when storage operations fail, responses now complete gracefully with status: "failed" and error.code: "storage_error" instead of crashing or leaving responses permanently stuck at in_progress. Covers all execution modes (streaming, background+streaming, background+non-streaming, synchronous). For streaming responses, terminal SSE events are buffered, persistence is attempted, and on failure the terminal event is replaced with response.failed carrying error_code="storage_error". Synchronous persistence failures return HTTP 500 with the storage error details.
Foundry storage logging now includes the traceparent header (W3C distributed trace ID) in all log messages, enabling correlation between SDK log entries and backend distributed traces.

Fixed crash in FoundryStorageLoggingPolicy when a transport-level failure (DNS resolution, connection refused, timeout) occurs before any HTTP response is received. The policy previously attempted to access response.headers unconditionally, raising an unrelated exception that masked the real transport error. Transport failures are now logged at ERROR level and the original exception propagates cleanly.
Fixed ResponseContext.get_input_text() and ResponseContext.get_input_items() silently dropping text when ItemMessage.content is a plain string. String content is now correctly expanded into MessageContentInputTextContent.

Removed x-ms-request-id from Foundry storage response logging (unused service header).
