Archive vs Distribution fuzzy

I feel the discussion in is quite confusing about Source Distributions and Source Archives. They are clearly treated as separate, with a Source Archive coming "prior to creation of a Source Distribution" in the glossary, but the output of build --sdist is a "Source Archive" and everything below is called an archive, with "You should always upload a source archive and provide built archives for the platforms your project is compatible with.".

Is this making a false distinction between a distribution and an archive? All tools (python -m build --sdist and python setup.py sdist) make a source distribution which is in an archive format, and the only non-distributable archive I know of is the one GitHub tends to make from tags, which is not something that needs discussion here.

Inizia con la definizione nel glossario di “Source Archive” e con le sezioni che descrivono build --sdist, le distribuzioni sorgente e gli archivi generati. Analizza come vengono usati questi termini nella documentazione, quindi determina se la distinzione è intenzionale e rendi coerente la terminologia; il lavoro è completato quando il glossario e le istruzioni interessate non si contraddicono più.
