Concurrent agent memory queries melted under alert storms: 140 recall calls cut to 4, P99 latency down to 185ms

The author's team built an incident-response agent using Hindsight memory and stress-tested what happens when a large alert storm triggers many concurrent memory queries.
- Failure mode: the naive approach generated 140 outbound recall calls during a storm, with P99 recall latency hitting 9,120ms
- Fix: structural fingerprinting plus single-flight coalescing reduced calls to 4 and P99 latency to 185ms (98% drop)
- The article covers the failure mode, the fix architecture, Hindsight's recall/retain flow, and lessons on concurrency in agent memory design
