Enum Throttle 

pub enum Throttle {
    RetryAfter(Duration),
    Exhausted,
}

How a 429 should be handled. Observed 2026-07-27 against the real API: a throttle 429 carries x-should-retry: true, a rate_limit_error body, and NO anthropic-ratelimit-unified-* headers at all - so “the account is spent” and “slow down for a moment” are different events that look similar. Treating a throttle as exhaustion would abandon a perfectly good account; treating exhaustion as a throttle would retry a wall forever.

Variants

RetryAfter(Duration)

Retry the SAME account after this long.

Exhausted

Do not retry here - the account is out of quota (rotate instead).
