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. sqlalchemy.JSON maps complex nested dictionary and list structures with automatic serialization and deserialization
  2. sqlalchemy.JSON supports JSON path element extraction and filtering using subscript expressions with type coercions like as_string and as_integer
  3. sqlalchemy.JSON with none_as_null=True distinguishes between SQL NULL and JSON null literal values in database storage and queries
  4. reassigning a modified dictionary to a sqlalchemy.JSON column triggers Session change tracking and persists updates
