How this guide is layered
Every guide on this site is read through the same twelve layers, in the order that fits its topic: data, format, network, validation, tax, accounting, lifecycle, evidence, direct intent, transaction, jurisdiction, obligation. The layers are a reading method, not a claim about any single system.
Evidence basis: Primary sources named in the sources section, checked 2026-10-27; country guides are dated research routes, not mandate calendars. Scope: General educational information only; no individual legal, tax, accounting or compliance advice; jurisdiction and transaction specific checks remain with the reader.
