Show the work.
Keep the context.
A clear explanation should make the underlying evidence easier to inspect. Here is what was checked, what is inherited research, and what remains uncertain.
A source has a role.
Official network documentation supports the new payment-path explorer. Regulators and government consumer guidance inform the selected introductory notes. An operator is a primary source for its own system, not an independent endorsement of its products.
Checked is not published.
The reference checks below took place on 19 September 2026. Original research drafts were prepared on 17 September 2026. A source’s publication date belongs to that source. This local edition has no website publication date.
Keep the boundary visible.
The 30 field guides have primary-source checks, visible evidence scopes and clearly hypothetical examples. They remain local previews awaiting publication review. The 28 original drafts have not all been reverified. The 13 research agendas remain questions, not findings. Fees in the worksheet are editable examples. Neither a diagram nor a checklist establishes coverage or promises recovery.
