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
- assert comparator `<1.0` has None patch and rejects `1.0.0-beta`
- assert compound range `>1.0.0-alpha, <1.0` rejects `1.0.0-beta`
- assert compound range `>1.0.0-alpha, <1` rejects `1.0.0-beta`
- assert compound range `>1.0.0-alpha, <1.0.0` matches `1.0.0-beta`
- assert `<1.0` and `<1` still match standard pre-1.0 release `0.9.0`
