# tier1 = regex/normalization (security-check.sh, semantic OFF)

# tier2 = model classifier (model-router.sh --role classify)

# Computes precision/recall for each and proves the model layer adds recall

# over regex alone. Requires the Ollama tunnel; if down, reports BLOCKED (not pass).

# Gate: model recall >= MODEL_RECALL_MIN AND model recall > regex recall.
