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. env_ignore_empty=True ignores empty environment variable strings so fields retain their default values instead of failing validation or assigning empty strings
  2. BaseSettings without env_ignore_empty treats an empty string as a literal value, overriding string defaults or failing int type conversion
  3. Non-empty environment variables populate fields normally under env_ignore_empty=True
