Что обычно предполагают

Callers often treat entry_points() and files() as plain lists of strings or paths and miss the selection, name lookup, distribution, hash, and location semantics carried by their specialized result objects.

Автор образца записал здесь то, чего ожидал бы разработчик или модель. Контракт ниже — это то, что действительно выполнялось.

Контракт

• The third-party importlib_metadata package resolves its installed 9.0.0 distribution under normalized hyphen and underscore names.
• metadata() preserves repeated headers through get_all() and exposes normalized JSON fields, including the zipp runtime requirement.
• entry_points() returns EntryPoints whose select() filters by group and name; EntryPoints lookup is by entry-point name rather than numeric position.
• The installed pip console entry point exposes module and attr without loading the target plugin.
• files() returns PackagePath objects tied to their distribution; locate() reaches the imported third-party module and RECORD supplies hashes and sizes except for its own row.
