Typed Pipelines: Make Spark Renames Fail at Compile Time

Field notes

The service works against a customer's existing repository rather than offering a hosted dashboard. Its five-part scope includes documenting implicit schema assumptions, introducing case classes and TypedEncoders at stage boundaries, running migration paths in parallel, and wiring Spark/Scala-specific artifacts. The page names Frameless 0.17.0, supports Scala 2.12 and 2.13, and lists Spark 3.4.4–4.2.0. Property-test generation is explicitly tuned through Frameless environment variables to avoid exhausting the heap.
