Commonly assumed
Exhausted retries always raise RetryError, including result predicates with a fallback callback and exception retries configured with reraise=True.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- A result predicate that still requests retry after the third attempt raises RetryError whose last_attempt is a successful Future containing the rejected None result.
- retry_error_callback receives the third RetryCallState and returns its fallback value instead of raising RetryError.
- Exception exhaustion raises RetryError by default and retains the final ValueError in last_attempt.
- With reraise=True, exception exhaustion raises the final ValueError directly after the same bounded attempt count.
