After a failed or timed-out store read the responder denies for LOOKUP_FAILURE_WINDOW (3 s) without a new lookup, so a burst of requests during an outage costs one lookup instead of one per request. Three edits besides the code in main.rs belong to this change: - swarm-metrics-auth/Cargo.toml gains tokio's test-util dev-dependency because the burst test runs on paused time (start_paused) to let a hanging store sleep past LOOKUP_TIMEOUT without a real 5 s wait. - docs/swarm/services.md gains the sentence that a failed or timed-out read is denied for three seconds without a retry, which documents the window this change adds. - docs/swarm/credentials.md gains the clause "every three seconds while the store fails" on the Grafana bearer row, which documents the same window in the secrets table.
