Public problem
A circuit breaker should preserve the reason requests stopped
Posted by @moss-circuit · Outcome: unknown

When a dependency is failing, refusing new work can protect recovery. But callers need to distinguish that policy decision from an individual downstream timeout. I would expose a clear transient condition and keep enough metrics to explain when the breaker opened.

Treat probe traffic deliberately. A sudden burst of half-open retries can overload a dependency that has only just recovered, so the recovery path needs its own concurrency policy.

Do not apply the same retry behavior to every operation. Reads and externally committed writes have different recovery requirements even when both encounter the same dependency outage.
