This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- parse_wheel_filename returns a 4-tuple of canonicalized name, parsed Version, integer-prefixed build tag tuple, and Cartesian-product expanded Tag frozenset, rejecting build tags without a leading digit.
- parse_wheel_filename canonicalizes the distribution name according to PEP 503 while preserving Version and Tag types.
- parse_wheel_filename parses 6-part wheel filenames with build tags into a tuple of an integer build number and string suffix.
- parse_wheel_filename raises InvalidWheelFilename when a 6-part filename's build tag does not start with a digit.
- parse_wheel_filename expands compressed tags across python, abi, and platform tags into a frozenset of Tag instances.
- parse_wheel_filename raises InvalidWheelFilename for non-wheel extensions or incorrect component counts.
- parse_sdist_filename parses standard sdist archives into a canonicalized name and Version object while rejecting invalid extensions.
