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
- tar.create packages files and nested directories into uncompressed and gzip-compressed tar archives
- tar.extract unpacks archive contents restoring file hierarchy and data integrity
- tar.create and tar.extract support synchronous operations via the sync option
- tar.create and tar.extract filter entries using custom predicate functions
- tar.extract supports stripping leading path components using the strip option
