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. escape converts HTML special characters (&, <, >, ', ") into corresponding HTML entities
  2. escape preserves strings that do not contain HTML special characters
  3. unescape converts HTML entities (&amp;, &lt;, &gt;, &#39;, &quot;) back to original characters
  4. unescape preserves strings without HTML entities
  5. escape and unescape are inverse operations for valid HTML strings
  6. escape and unescape handle empty strings and non-string inputs coerced to string
