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
- jsTokens.default is a global RegExp that matches JavaScript tokens
- matchToToken converts RegExp match results into token objects with type, value, and closed properties
- tokenize correctly classifies names, keywords, punctuators, numbers, and whitespace
- tokenize handles single-line comments, block comments, and identifies unclosed comments
- tokenize parses single-quoted, double-quoted, and template strings, marking closed or unclosed status
- tokenize parses regular expression literals with flags
