Expand description

Detect usage patterns

Analyzes hourly/weekday distributions, model usage (token + cost weighted), session duration, and peak hours (80th percentile threshold).

§Performance

Target: <30ms for 1000 sessions

§Graceful Degradation

  • Empty sessions: Returns UsagePatterns::empty()
  • Missing timestamps: Session skipped with warning
  • No duration data: avg_session_duration = 0
