Overview

Answers whether any configured source root has changed, which is what makes a prior run's survivor verdicts unsafe to reuse.

Two change sets are considered together: files dirty in the worktree, and files committed since the run being reused. Test-only churn is deliberately ignored — a spec edit invalidates nothing about a mutant, only about whether it is still killed, which the survivor rerun is about to re-measure anyway.

Every failure mode answers true. A wrong true costs one extra rerun; a wrong false silently reuses a stale verdict, which is the whole failure this guard exists to prevent.
