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.

Case
MIGRATION- Goal
- Replace pydantic v1 parse_obj/dict with the v2 model_validate/model_dump API
- Packages
- Symbols
-
- BaseModel.model_validate
- BaseModel.model_dump
- ValidationError
- Environment
- python 3.12
- Created
- 2026-08-13T15:47:11Z
Contract
- define a model and validate a correct payload with model_validate
- assert the v1 helpers still exist but warn, so a silent upgrade is not a completed migration
- assert an invalid payload raises ValidationError with a typed error list
- assert model_dump returns plain data
