"""PyPI: latest stable via the modern simple index.
|
|
|
|
The legacy `/pypi/<name>/json` endpoint's `info.version` includes yanked and
|
|
pre-release versions, which is exactly the fail-green bug this gate must not
|
|
have. The simple v1 JSON carries per-file `yanked` flags, so a version counts
|
|
only when at least one of its files is still installable.
