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
- An outer top-level pandas.merge matches one missing Int64 key across both sides and reports three both, two left_only, and one right_only rows.
- validate='one_to_one' raises pandas.errors.MergeError when an ordinary left join key is duplicated.
- left_anti returns only keys 1 and 4 while right_anti returns only key 2, excluding the missing key because pandas treats it as matched.
