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
- fs.move rejects with 'dest already exists.' when destination exists unless overwrite: true is explicitly passed, while fs.copy defaults overwrite to true
- fs.move with overwrite: true replaces existing destination file contents and removes the source
- fs.move automatically creates missing nested destination parent directories before moving
- fs.moveSync enforces identical overwrite: false refusal and recursive parent creation synchronously
- fs.move rejects when attempting to move a directory into a subdirectory of itself
