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 init kwargs override os.environ and .env files
  2. assert os.environ overrides .env file definitions
  3. assert .env file values override class field defaults
  4. assert passing a nested dict in init kwargs deep-merges with env and .env sources
  5. assert passing an instantiated model in init kwargs masks all lower-priority env sources with instance defaults
  6. assert nested environment variables are ignored unless env_nested_delimiter is explicitly set
  7. assert nested models without env_nested_delimiter require a JSON-encoded string in the parent env variable
