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 that calling `replace` with a default-set changes `compare_by_identity?` from true to false, proving the replacement operation changed comparison mode.
- assert that after that replacement, a value-equal probe object is now found by `include?`, silently showing identity mode was not retained.
