  • Gates & Guardrails Confidence thresholds, safety boundaries.
  • Dynamics & Evolution Feedback loops, skill drifts, metrics.

Key Differentiators

  • Models evolving relationship over time
  • Defines trust-building milestones
  • Captures emergent pair capabilities
  • Balances autonomy with accountability
