What happens

modelSettings.retry.policy for the openai:agents provider accepts the presets never, providerSuggested, networkError, retryAfter, and httpStatus, any and all objects. Any other value is silently ignored:

• A misspelled preset such as networkErrors resolves to no policy, so the configured retry behavior never applies.
• Inside any or all, an invalid entry is dropped and the rest still run. all: [{ httpStatus: [429] }, networkErrors] retries on every 429 instead of only on 429 network errors.
• Malformed objects such as { any: [] } or { httpStatus: 429 } are also ignored or crash with an unrelated error.

Reproduce

providers:
  - id: openai:agents:support-agent
    config:
      agent:
        name: Support Agent
        instructions: Answer briefly.
        model: gpt-5-mini
      modelSettings:
        retry:
          maxRetries: 2
          policy: networkErrors

The eval runs with no warning and the typo has no effect.

Expected

An invalid retry policy fails with a clear configuration error that lists the supported values, before any request is sent.
