-
-The repo now ships a privacy-safe metrics contract for fleet monitoring:
-
-```python
-from crisis.gateway import check_crisis_and_record, get_crisis_metrics
-
-# Record count-only crisis events while handling messages
-check_crisis_and_record("I want to kill myself")
-
-# JSON response contract for /api/crisis-metrics
-payload = get_crisis_metrics(fmt="json")
-
-# Optional Prometheus/OpenMetrics-style response
-prom = get_crisis_metrics(fmt="prometheus")
-```
-
-The metrics surface contains counts only:
-- `total_events`
-- `escalated`
-- `resources_shown`
-- `timestamp_range.start`
-- `timestamp_range.end`
-
-No message content, indicators, or user identifiers are retained.
-
-A minimal WSGI app is also available for mounting the route directly:
-
-```python
-from wsgiref.simple_server import make_server
-from crisis.metrics import crisis_metrics_app
-
-with make_server("127.0.0.1", 8645, crisis_metrics_app) as httpd:
-    httpd.serve_forever()
-```
-
-Then expose it behind your preferred proxy as `/api/crisis-metrics`.

-Session-level crisis tracking and escalation for the-door (P0 #35).
-
-Tracks crisis detection across messages within a single conversation,

-
-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)

-    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)
-

+When a Man Is Dying — Despair/Suicide Detection System
 
-This module is a thin wrapper around crisis.detect for backward compatibility.
-All unique patterns have been merged into crisis/detect.py (see issue #40).
+Standalone detection module that parses incoming text for
+despair and suicide indicators, classifies into tiers,
+and returns structured response with recommended actions.
 
-This module will be removed in a future release.
+Tiers:
+  LOW      — General sadness, stress, difficult times
+  MEDIUM   — Hopelessness, isolation, worthlessness
+  HIGH     — Active despair, mentions of death, "can't go on"
+  CRITICAL — Imminent risk, explicit intent, plan, method
+
+Integration:
+  Designed to work with crisis/ module from PR #4.
+  When crisis/ is available, uses it as the detection backend.
+  Falls back to internal detection when crisis/ is not present.
