Tail Latency & System Behavior

Runnable Java experiments on the failure patterns that show up under real load: tail latency, queueing, hedged requests, coordinated omission, backpressure, and SLO engineering. Deterministic outputs, checked-in CSVs, reproducible on any machine.

Queueing Theory for Engineers
A deterministic Java queueing simulation where p99 stays at 10ms through rho=1.00, then jumps to 109ms at rho=1.05 and 605ms at rho=1.30 while service time stays fixed.

Why Average Latency Lies
A deterministic Java simulation where baseline p99=34ms becomes fan-out p99=597ms without changing the downstream latency sampler. Average latency is structurally incapable of catching that tail pain.
