fidelity
This term describes a strict adherence to a standard, whether that standard is a moral commitment to a person or a technical requirement for accuracy. In interpersonal contexts, it carries a heavy weight of honor and devotion, often implying a lifelong or sacred bond.
In technical and academic spheres, the word shifts toward the concept of precision. It describes the absence of distortion or error, where the value of the reproduction is measured by how little it deviates from the original source.
