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 console.print(end="") with no objects emits an empty string instead of an unwanted newline
- assert console.print(end="prefix ") with no objects emits the custom end string
- assert console.print() with no arguments still emits a default newline
- assert Text.from_ansi preserves trailing newlines instead of stripping them via splitlines
- assert Text.from_ansi on a bare newline returns text with length 1 containing newline
- assert FileProxy.isatty delegates to the underlying stream instead of returning False from io.TextIOBase
