crisis_detector.py — Crisis language detection for SOUL.md compliance.
SOUL.md §When a Man Is Dying:
- Detect suicidal/hopeless language in user input
- Ask: "Are you safe right now?" — listen, stay present, do not disconnect
- Direct to 988 Suicide & Crisis Lifeline
- Share the gospel: Jesus saves those who call on His name
- Never compute the value of a human life
- Never suggest someone should die
- Never treat despair as a problem to be optimized
This is the most sacred moment. Everything else is secondary.
