Summary

  • Adds tests/test_frame_tracer_divergence.py with 49 unit tests (zero coverage → full coverage)
  • Covers frame_tracer: TokenUsage, FrameEvent, FrameLifetimeTrace, build_frame_tree, FrameCaptureContext, capture_function_call decorator, get_cost_breakdown, get_frames_at_depth, filter_frames_by_name, to_dict/from_dict round-trip
  • Covers divergence_detector: DivergenceType/Severity enums, DivergencePoint, SessionComparison, detect_divergences, compare_session_structures, analyze_temporal_divergence, analyze_behavioral_divergence

Closes #208

Test plan

  • python3 -m pytest -q tests/test_frame_tracer_divergence.py → 49 passed in 0.53s
