+- New `value_error_thresholds` parameter added to both `evaluate_semantic()` and `evaluate_agentic()` for range-based absolute error tolerances on numeric property value comparisons:
 
-### Added
+  - Accepts a dict mapping `(min, max)` tuples to absolute error thresholds. When a ground-truth value falls inside a range, the extracted value is accepted if `|extracted - ground_truth| ≤ threshold`. Values outside all configured ranges fall back to exact comparison.
+
+  - **Semantic evaluation**: handled inside `_is_value_in_range()` via the new `_get_error_threshold()` helper in `MaterialsDataSemanticEvaluator`.
+
+  - **Agentic evaluation**: a new `GetValueErrorThresholdTool` (CrewAI `BaseTool`) is added to the composition evaluator agent when thresholds are configured. The agent calls this tool with the reference value to retrieve the tolerance before deciding on each numeric match. No tool is added and no prompt changes are made when no thresholds are provided.
