Sources
The wiki’s source registry lists every external URL cited by an article. Each entry carries the URL, the language of the source, and the date it was retrieved.
Definition
A source in this wiki is an external document that backs a factual
claim in an article. Sources are catalogued under Wiki/sources/,
each as a small Markdown stub. Articles refer to a source by its slug,
enclosed in square brackets with the source: prefix.
Scope
A source is not a bibliographic reference. It is the URL plus a short provenance note, sufficient to verify the quoted claim.
Placeholder — the real registry lives here once the source database
populates. The Wiki/sources/ directory holds several hundred first-party
stubs that already underpin the trick data set.
