mandatory infrastructure
The invoice no longer travels alone.
Behind the move to digital sit intermediaries, directories, processing steps, contracts and fallback paths. The investigation starts with this concrete architecture instead of reducing the debate to a regulatory deadline.
The EPUB adds an introduction and conclusion to the five articles. It preserves sources, limitations, canonical links and text alternatives for the infographics so that every element can be checked.

Five stages, five decisions that must be testable.
The centre line follows the invoice. Above it is what the records establish. Below it is what still needs to be published, specified or tested.

what the book asks
Answers that anyone can verify.
