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. PluginManager discovers and executes hook implementations with tryfirst and trylast ordering
  2. Hook specifications with firstresult=True return the first non-None result from registered implementations
  3. Modern generator hook wrappers with wrapper=True and legacy hook wrappers with hookwrapper=True intercept and modify hook outcomes
  4. Historic hooks record execution history and replay events to plugins registered after the call
  5. PluginManager validates implementation argument specifications and raises PluginValidationError on unknown arguments
  6. PluginManager controls plugin lifecycle including registration, unregistration, blocking, and subset caller creation
