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. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. assert parseRegExpLiteral parses regular expression literal into AST with pattern and flags
  2. assert RegExpParser parses ECMAScript regular expression patterns with configurable options
  3. assert RegExpValidator validates regular expression literals and triggers callbacks
  4. assert validateRegExpLiteral validates regular expressions and throws RegExpSyntaxError on syntax errors
  5. assert visitRegExpAST traverses AST nodes and invokes visitor callbacks
