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
- import mergeProcessCovs and cloneProcessCov from @bcoe/v8-coverage
- merge multiple V8 ProcessCov reports containing multiple scripts and functions
- assert script URLs are matched and scriptId values are normalized sequentially
- assert execution counts for corresponding function root and branch ranges are summed across runs
- assert scripts unique to a single run are preserved in the merged ProcessCov output
