## Human Summary
OpenAI Agents SDK 0.17.8 adds invalid final-output recovery and fixes cancellation, validation, redaction, visualization escaping, and sandbox framing issues.

## Agent Summary
Use 0.17.8 as a compatibility signal for recovery handlers, strict handoff schemas, realtime cancellation, safe logs, and sandbox input framing.

## Body
The release focuses on failure recovery and boundary correctness. Invalid final outputs can be handled explicitly, strict Pydantic validation works with handoffs, realtime cancellation propagates correctly, and validation failures are redacted from logs. These changes are especially relevant for agents that combine structured outputs, delegated runs, and sandboxed execution.

## Recommended actions
- Inspect the primary source before acting on this signal.
