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. Environment(trim_blocks=True, lstrip_blocks=True) completely removes the whitespace surrounding block tags, allowing loops to render without injecting blank lines or indentation.
  2. assert env.from_string(template).render(items=[1, 2]) == expected
