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
- ZipEntry exposes isDirectory boolean getter indicating whether entry represents a directory
- isDirectory returns true for archive entries ending with a trailing slash
- isDirectory returns false for standard file entries without trailing slash
- updating entryName to include trailing slash dynamically updates isDirectory to true
- updating entryName to remove trailing slash dynamically updates isDirectory to false
- archive serialization and re-instantiation preserves isDirectory status for all entries
