Data engineering pipeline​

Ambient Core ships the catalog (typed data options and metrics) and ambient_pipeline helpers. Lakehouse jobs and schedules live in the application repository that pins a core tag.

Canonical order: map columns → coerce types → unpivot → stamp lineage → (optional Silver validate) → contract assert → write. Gold vertical products evaluate catalog formulas with ambient_calc after Silver.
