Overview

Executes a single workload's warmup and measured samples in the current process (spec section 12.2, steps 4-9). Process isolation across workloads is layered on top by ProcessRunner. SQL count/ duration, allocations, and GC deltas are collected only inside the workload's explicit Perfgate.measure block; duration falls back to wall-clock timing of the whole workload when Perfgate.measure is never called (spec section 13.1).

A failed assertion or raised exception inside the workload is an execution error, not a performance regression (spec section 12.2): it aborts this workload's run and is reported as status: "error" rather than raising out of call.
