retry

Retry decorator + report for connection-style transient errors.

Wraps a callable; retries on a configurable set of exceptions with exponential backoff. Exhausted failures are pushed onto a RetryReport so the eval harness can surface them in the final report rather than aborting.

funccall_with_retry

(fn, *args, *, max_attempts=5, backoff_base=1.0, backoff_cap=16.0, retriable=None, report=None, context='', **kwargs) -> T | None

Call fn(*args, **kwargs) retrying on transient errors.

On exhaustion: records to report (if supplied) and returns None. Non-transient exceptions propagate immediately - eval bugs shouldn't be silently retried.
