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
- env_ignore_empty=True ignores empty environment variable strings so fields retain their default values instead of failing validation or assigning empty strings
- BaseSettings without env_ignore_empty treats an empty string as a literal value, overriding string defaults or failing int type conversion
- Non-empty environment variables populate fields normally under env_ignore_empty=True
