Train/inference skew (step 7/7) · feature pipelines, experiment tracking, and registries

Checkpoint

One last thing before we move on. Same surface as a write step — but the lesson doesn't complete until this passes.

Checkpoint. Produce a full skew report. Write skew_report(train, serve) that returns both directions — features missing at serve and unexpected extras at serve — each sorted:

missing at serve: ['age']; unexpected: ['zip']
