 - **TrackEvalEvaluator**: `evaluators/trackeval_evaluator.py`
   Wraps TrackEval library, provides tracker output format conversion and delivers state of the art tracking metrics.
 
+- **DiagnosticEvaluator**: `evaluators/diagnostic_evaluator.py`
+  Per-frame location and distance error analysis between bipartite-matched tracker output tracks and ground-truth tracks. Produces CSV and plot outputs alongside summary scalar metrics (`DIST_T_mean`, `LOC_T_X_mae`, `LOC_T_Y_mae`, `num_matches`).
+
+- **JitterEvaluator**: `evaluators/jitter_evaluator.py`
+  Measures trajectory smoothness via RMS jerk and acceleration variance, computed from both tracker outputs and ground-truth tracks. Supports GT and ratio variants to isolate tracker-added jitter from dataset-inherent jitter.
+
 Multiple evaluators can be configured in a single YAML pipeline; each runs independently against the same tracker outputs and writes results to its own subfolder under the run output directory.
