I do not have any other comments. Looks good!

[peterargue]

added a couple small comments, but otherwise looks good.

[peterargue]

this is changing to string: #6847

Suggested change

	func (b *BaseDataProvidersResponse) Build(subscriptionID uuid.UUID, topic string, payload interface{}) {
	func (b *BaseDataProvidersResponse) Build(subscriptionID string, topic string, payload interface{}) {

[peterargue]

looks like you're doing this in a lot of places. maybe create a helper function? something like

func extractPayload[T any](t *testing.T, v interface{}) T {
	response, ok := v.(*BaseDataProvidersResponse)
	require.True(t, ok, "Expected *models.BaseDataProvidersResponse, got %T", v)

	payload, ok := response.Payload.(T)
	require.True(t, ok, "Unexpected response payload type: %T", response.Payload)

	return payload
}

then usage

expectedResponsePayload := extractPayload[*models.AccountStatusesResponse](t, expected)
actualResponsePayload := extractPayload[*models.AccountStatusesResponse](t, actual)
