A digital twin can organize geometry, measurements and knowledge about an asset. A system that also promises to predict future conditions or compare interventions makes additional commitments. It needs a model of change, a way to update that model from evidence, and an account of uncertainty. Calling the system a world model is useful only […]

To support a conservation decision, we also need to know when the image was taken, what else was measured, which interpretation was proposed, and who reviewed it. Those relationships do not emerge automatically from a mesh or a textured surface. A useful first step is […]

An assistant can produce a fluent explanation of a sensor reading without knowing whether that reading is new, whether the same situation occurred last winter, or whether a proposed intervention was actually carried out. For conservation work, those omissions are not details. They are part of the decision. A useful agent therefore needs an evidence […]
