-"""Behavioral Pattern Detection — crisis risk from usage patterns.
-
-Detects crisis signals from HOW someone uses the system, not just
-what they say. Complements content-based crisis detection.
-
-Behavioral signals:
-- Frequency spike (anxiety/agitation)
-- Frequency drop (withdrawal/isolation)
-- Late-night messaging (2-5 AM)
-- Session length increase (loneliness)
-- Abrupt termination after emotional content
-- Return after long absence

-Part of Epic #102 (Multimodal Crisis Detection).

+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.
