Operational Remediation Reports

Future State Remediation Report

Settle a future with a recorded failure count and turn the resolved value into an observe, retry, or failover remediation action.

settled result A `concurrent.futures.Future` resolved with `set_result` exposes a deterministic value, so the remediation action depends only on the recorded failure count.
