What this is

What counts as Data contracts enforcement?

A data contract specifies what a table or stream must always look like — column names, types, semantics, freshness — and is enforced by tooling rather than by Slack reminders. Tools in this category either declare contracts on the catalog side, or block writes/reads that violate them on the testing side. The strongest implementations do both.

Inclusion here is one boolean on each tool's structured profile — if a tool you'd expect is missing, the field is recorded false or not yet verified, never an editorial call. See the methodology for how each field is sourced.
