   ]! 4        R# R# )-ah  Evaluate Rego policies against attestation data using OPA.

Runs each risk-dimension policy against the appropriate attestation type
and returns structured results per-policy. This replaces the ad-hoc Python
risk scoring with formal, auditable policy evaluation.

Policy dimensions:
  - network_exfiltration: evaluates command-run attestation
  - credential_harvesting: evaluates command-run attestation
  - code_execution: evaluates command-run attestation
  - persistence: evaluates command-run attestation
  - supply_chain: evaluates pip-install attestation
  - package_signing: evaluates pip-install attestation
