"""
mentor_feedback_engine.py — AIVA Mentor Council Preference Pair Generator

Reads recent AIVA interactions from PostgreSQL and runs them through 3 mentor
evaluation lenses (Socrates, Aristotle, Plato). Each lens uses pattern matching
to evaluate response quality without requiring an LLM call.

Generates synthetic preference pairs in the pl_preference_pairs table that feed
AIVA's RLM (Reinforcement Learning from Mentorship) learning loop.

Mentors:
  SOCRATES  — Checks reasoning quality and unsupported certainty
  ARISTOTLE — Checks factual accuracy against Genesis constants
  PLATO     — Checks brand alignment, tone, warmth, and constitutional adherence

Usage:
  python mentor_feedback_engine.py [--dry-run] [--limit N] [--hours N]

  --dry-run     Print evaluations without writing to DB
  --limit N     Process at most N interactions (default: 100)
  --hours N     Look back N hours for interactions (default: 24)

Designed to be run as a scheduled job (cron or n8n trigger).
