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. puddle.NewPool initializes a type-parameterized resource pool with constructor and MaxSize config
  2. pool.Acquire creates and leases a resource handle whose Value is accessible and increments AcquiredResources
  3. resource.Release returns the resource to the pool making it available as an idle resource
  4. resource.Destroy removes the resource from the pool invoking the Destructor callback
  5. pool.Close closes the pool and causes subsequent Acquire calls to return ErrClosedPool
