Checkpoint
One last thing before we move on. Same surface as a write step — but the lesson doesn't complete until this passes.
Checkpoint. Route a batch of tasks to packages. Write route(tasks)
that returns the list of packages for each task (use the chapter's map;
"unknown" for anything unlisted).
For ["tables and csv", "deep learning", "pretrained llm"]:
['pandas', 'torch', 'transformers']
