is_retryable

Function: warmhub.is_retryable

is_retryable(error: object)

Whether an error kind is generally safe to retry.

True for exactly NETWORK, CANCELLED, BACKEND, RATE_LIMITED. Every other kind — including backend pass-through domain codes — is False. Conservative by design: read WarmHubError.message before giving up on a False, because the backend reuses some codes for transient conditions.

Asking this about a cancellation propagates it rather than answering: to_warmhub_error refuses to classify a BaseException that is not an Exception, and this function must not convert that refusal into a True that sends a cancelled task back around a retry loop.
