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 empty directories and directories containing only non-Ruby assets or hidden dotfiles do not autovivify namespace modules and raise NameError on constant access rather than resolving to Module instances
  2. assert loader.all_expected_cpaths only tracks directories that contain Ruby source files, omitting empty and non-Ruby directories while cpath_expected_at still computes hypothetical inflection names
  3. assert accessing nested constants through directories lacking matching Ruby files autovivifies intermediate namespace segments strictly as Module instances, which causes class re-opening to fail with TypeError
  4. assert providing an explicit matching Ruby file defining a Class allows subsequent nested classes and class re-openings without TypeError
  5. assert loader.eager_load walks all valid Ruby file trees and autovivifies intermediate modules while leaving empty and non-Ruby directories completely uninitialized
