Research direction

Open algebra-core/src/main/scala/algebra/instances/double.scala at line 8 and inspect the surrounding instance definitions. Confirm the missing package object matches the project’s existing patterns, then run the relevant algebra-core tests; done means the package object is present and the tests pass.
