# `harness.runner`

A {py:class}`~milp_flare.harness.runner.base.Runner` is the compute backend that
launches the FLARE agent container for a populated working directory. Each
{py:meth}`~milp_flare.harness.runner.base.Runner.start` call returns an
{py:class}`~milp_flare.harness.runner.base.AgentRun` handle that owns the
lifecycle of the in-flight run.
