 ## The decision
 
-Each Use Case (a subcategory, or a flat section) lists at most its Obvious Choices — up to 3, plus up to 2 marked Challengers, hard maximum 5 (numbers provisional, to be reviewed after the prune). Admission is by maintainer editorial judgment, informed primarily by PyPI download counts rather than GitHub stars, and stated as final; judgment overrides the signal's known failure modes (CI/dependency-inflated counts, model releases consumed as weights rather than pip installs, large-but-specific audiences misread as "niche"). Once a Use Case is at cap, the only way in is Displacement: the PR names the entry it replaces and argues the newcomer does that job better. Use Cases are defined by the list's existing structure; an entry PR can never create the subcategory it needs. Standard-library entries hold a slot only where the stdlib module is itself the obvious choice. The existing stock gets the same test retroactively: a staged, worst-first prune (per-section sweep commits), with removed entries deleted outright — git history is the archive. Resources sections (Newsletters, Podcasts, Websites) are out of scope for now.
+The list's scope test is "serves Python developers", replacing the old "primarily written in Python (>50%)" requirement: implementation language and packaging are irrelevant when Python developers use the thing in their Python work (uv and ty are Rust; agent skill packs are markdown), while a pure-Python project nobody uses in Python work does not belong.
