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
- Double-quoted values interpret escape sequences whereas single-quoted values preserve characters literally in python-dotenv parsing
- assert inline comments are stripped from unquoted values but preserved inside quotes
- assert leading export prefixes are stripped from environment variable definitions
- assert variable expansion ${VAR:-default} resolves to default when the variable is unset
- assert circular variable references resolve safely to empty strings without recursion errors
- assert get_key retrieves values and returns None for missing keys
- assert set_key modifies key bindings in place preserving surrounding comments
- assert unset_key removes bindings returning (True, key) for existing keys and (None, key) for missing keys
