# Harness

Use Harness when the task needs configured build/test validation. Read `docs/HARNESS.md` and the relevant project configuration. Run the complete configured validation explicitly with:

```powershell
python scripts/execute.py
```

For focused development feedback, use the actual configured backend command directly. The runner returns exit 2 when no build metadata is configured and exit 1 for failed execution; neither is a passing solver check. Record commands, exit codes, and decisive results when they support the requested outcome.

Harness does not plan phases, dispatch agents, inject prompts, manage Git state, make commits, or authorize external solver use. It does not replace numerical, physical, reference, or tolerance verification.
