you:         why does payment-svc cap its pool at 40?

no captain:  pool.go sets it to 40. Likely to avoid exhausting database
             connections — a common pattern. You could raise it if your
             database handles more concurrent connections, though you may
             want to load-test first and monitor p99 during the rollout.

captain:     The July 3 flash-sale incident: pool exhaustion took p99 to 8s.
             adr-payments-pool-sizing fixed the cap because RDS connections
             were the real limit. PR-1841, services/payment/pool.go:88.

             goal-replace-apigee retires the layer in front of this service.
             Don't invest in the current routing.

Numbers

The measurement is a real agent doing real work: a headless Claude Code session answering questions about four pinned public repos — cloudnative-pg, etcd, kubernetes/enhancements, postgres — scored on what it cites. 72 questions, the same agent with and without a captain, 144 runs, Claude Sonnet 5 in both arms and as the judge.
