Four distinct schemas must align for correct data interpretation — source schema, storage schema, decision schema, and the model's own prior — and they are only simultaneously knowable at the moment of decision, meaning ontology merging should be deferred just-in-time rather than fixed upfront.
Reframes schema design from a static, upfront modeling exercise into a runtime concern tied to a specific decision context, which changes where ontology logic lives in a pipeline (at inference time, not in the warehouse DDL).
Any system that maps heterogeneous data into a decision-ready representation should treat the mapping as decision-scoped and computed at query/decision time rather than as a global invariant.
You will never know all four schemas (source, storage, decision, prior) at the same time except at the moment of decision.
There is no superschema.
