Uncertainty budget
Components kept separate, in the value's unit (literature SCHEMA.md, UNCERTAINTY_CALIBRATION.md): effective = max(sqrt(max(printed, reading, method)^2 + composition^2 + conversion^2), scatter). The method floor is the robust between-study scatter of the method class in ORCHID (calibrated) or a documented prior; printed values and printed uncertainties are unchanged.
| Value | Unit | Printed | Reading | Method (class, basis) | Composition | Scatter | Conversion | Effective |

| -130.5 | per mol-atom | 0.05 | unit 'per mol-atom' not convertible to kJ/mol-atom | unit 'per mol-atom' not convertible to kJ/mol-atom | ||||
| -122.1 | kJ/mol-atom | 0.05 | 3.9 (model_calculated, calibrated) | 3.9 | ||||
| -117.4 | per mol-atom | 0.05 | unit 'per mol-atom' not convertible to kJ/mol-atom | unit 'per mol-atom' not convertible to kJ/mol-atom |
