Define a Model Signature and Schema
Declare expected inputs and outputs explicitly.
What Goes In, What Comes Out
A model's signature declares exactly what inputs it expects and what outputs it returns. It is the model's contract. 📜
Why Signatures Matter
With a clear schema, callers know which columns and types to send. Bad input gets caught early instead of crashing at predict time.
