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 a Group with invoke_without_command=True renders [COMMAND] as optional in its usage help synopsis
  2. assert a standard Group with invoke_without_command=False renders COMMAND as required in its usage help synopsis
  3. assert invoke_without_command=True executes the root group callback when invoked without subcommands
  4. assert invoke_without_command=False exits with usage error code 2 when invoked without subcommands
