Next-Level Diagnostics.... with ZIO
summary
ZIO provides line‑level execution traces that show what did and would have happened across async and parallel regions, plus a fiber dump that lists every fiber, who it waits on and which fiber cancelled it. Features include lossless error causes, cancelable effects, deterministic testing, retry schedules (exponential from 10ms doubling to a 60s cap, up to 100 attempts), and an example load tester firing 1,000 concurrent requests — all demonstrated working end‑to‑end.
