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. readStringContents parses single-quoted strings with newline and hex escape sequences up to the closing delimiter
  2. readStringContents parses double-quoted strings with escaped quotes and tab characters
  3. readStringContents parses template literal contents across multiple lines and unicode escapes
  4. readCodePoint parses braced unicode code point escape sequences and returns the numeric code point
  5. readCodePoint parses 4-digit hexadecimal unicode escape sequences into character code points
