Update RISK_SYSTEM_PROMPT with two-step process (context understanding → criteria generation) - Add _default_source_context_message() method with clear producer context formatting - Change source_context injection from generic label to structured system message - Add debug logging for total criteria count across risk categories The prompt now instructs the LLM to use source context to generate MORE RELEVANT criteria rather than skipping evaluation entirely. This ensures consistent risk evaluation while tailoring criteria to the producer's domain.
