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 yauzl.fromBuffer opens a zip archive from a buffer and reads entries
- assert yauzl opens a readable stream for an entry and extracts uncompressed contents
- assert yauzl.validateFileName returns null for valid relative paths and error string for unsafe paths
- assert yauzl.dosDateTimeToDate converts MS-DOS date and time integers into a JavaScript Date
- assert yauzl.fromBuffer reports an error callback when given an invalid zip buffer
