Decision Traces as Multi-Layer Provenance Objects
Business decisions are rarely the conclusion of a single inference: they assemble facts, mechanisms, and scope judgements drawn from heterogeneous graph layers. This article argues the right primitive for capturing such assemblies is a decision trace — a typed graph walk traversing the context, causal, and knowledge layers of the enterprise architecture, recording the local material the decision rests on. The trace is a provenance object in the W3C PROV sense, typed by the layer it traverses — and that typing is what makes it operationally useful.
