# Proactive Diagnostics

GET https://api.loreos.app/v1/sessions/{session_id}/proactive-diagnostics

Explain whether this session would send a proactive message right now, and if not,
which configured thing is blocking it. Read-only: it evaluates the same candidate
selection and gates the scheduler uses without writing a decision, sending anything, or
touching cooldown state. Use it when proactive is enabled everywhere you can see but
the character still never reaches out.
