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. Markup.striptags() strips all HTML tags and comments, normalizes whitespace, unescapes entities, and returns a plain str.
  2. Markup.unescape() decodes HTML/XML entities back into raw text without modifying tags, returning a plain str.
  3. Markup.join() auto-escapes plain string iterable elements while preserving existing Markup instances, returning a Markup instance.
  4. Markup % string formatting auto-escapes plain string values in mappings and tuples while preserving numbers and Markup objects.
  5. Markup operations including repetition (*), slicing, splitting, and casing methods preserve the Markup return type.
