Routing calibration

Use tools/calibration/recipe/router_calibration_loop.py and the versioned probe schema in config/schemas/recipe-probes-v1.schema.json. Keep recipe changes in the local checkout; remote systems are validation mirrors only.

Treat endpoint credentials, hostnames, and private fleet details as secrets. Before a live run, validate the probe manifest and identify the exact recipe, backend, and rollback point. Record the evaluated inputs, outputs, and observed quality rather than inferring success from process health.

Run make check, then make verify DOMAIN=maintained-recipes for live recipe verification.
