dataModel.test.ts

// Tests drive the migration callbacks directly because @platforma-sdk/model's
// DataModelBuilder exposes no introspection / external-apply API. The builder
// wiring in dataModel.ts (the two `.migrate(...)` calls) is only exercised
// when a real block loads — these unit tests would still pass if someone
// deleted a `.migrate(...)` line while keeping the named callback exported.
