 """
-Session-level crisis tracking and escalation for the-door (P0 #35).
+Crisis Session Tracker for the-door <-> hermes-agent integration.
 
-Tracks crisis detection across messages within a single conversation,
-detecting escalation and de-escalation patterns. Privacy-first: no
-persistence beyond the conversation session.
+Tracks crisis session state, escalation history, and provides
+a bridge between the-door's web UI and hermes-agent sessions.
 
-Each message is analyzed in isolation by detect.py, but this module
-maintains session state so the system can recognize patterns like:
-  - "I'm fine" → "I'm struggling" → "I can't go on"  (rapid escalation)
-  - "I want to die" → "I'm calmer now" → "feeling better"  (de-escalation)
+Each browser session gets a unique crisis_session_id that is sent
+with every API request. This allows hermes-agent to:
+1. Receive crisis context from the-door's client-side detection
+2. Report escalations/de-escalations back to the-door's UI
+3. Maintain unified escalation history across web and CLI
 
 Usage:
     from crisis.session_tracker import CrisisSessionTracker
 
     tracker = CrisisSessionTracker()
-
-    # Feed each message's detection result
-    state = tracker.record(detect_crisis("I'm having a tough day"))
-    print(state.current_level)  # "LOW"
-    print(state.is_escalating)  # False
-
-    state = tracker.record(detect_crisis("I feel hopeless"))
-    print(state.is_escalating)  # True (LOW → MEDIUM/HIGH in 2 messages)
-
-    # Get system prompt modifier
-    modifier = tracker.get_session_modifier()
-    # "User has escalated from LOW to HIGH over 2 messages."
-
-    # Reset for new session
-    tracker.reset()
+    tracker.record("session-abc", level="HIGH", source="the-door", detail="keyword: 'can't go on'")
+    history = tracker.get_history("session-abc")
