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 Mustermann::Expander.new without additional_values defaults additional_values to :raise and raises Mustermann::ExpandError on unexpected keys instead of appending query params
  2. assert Pattern#expand without behavior argument defaults to :raise when extra keys are provided
  3. assert Expander with additional_values: :append formats extra keys as query string parameters
  4. assert Pattern#expand with :append formats extra keys as query string parameters
  5. assert Expander with additional_values: :ignore omits extra keys from the expanded path without error
  6. assert Expander with :append or :ignore still raises Mustermann::ExpandError when required pattern captures are missing
