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
- sync returns true for executable files and false for non-executable files
- isexe asynchronously returns true for executable files and false for non-executable files
- sync and isexe return false for non-existent files when ignoreErrors is true
- posix.sync and posix.isexe correctly detect executable status on posix platform
