## TL;DR

Data contracts define expected schemas, quality checks, service levels, and governance constraints between data producers and consumers.

## Core Explanation

Pipelines break downstream systems when a table loses a column, changes a type, violates freshness expectations, or silently degrades quality. Data contracts make those assumptions explicit and put them close to the pipeline.

For agentic analytics and ML systems, contracts help agents decide whether a dataset can be trusted, whether a pipeline change is breaking, and which downstream consumers need review before a schema change lands.
