Interview Prompt
The platform team is doing a year-end pass on a representative pipeline. Compose the operational state. Five-pillar coverage on the curated table; lineage catalog with column-level provenance; query tags with a cost rollup; slim-CI with the four test layers; environment data shapes (sample dev, slim-CI subset, masked staging, prod) with PII hashing; declarative-vs-imperative choice named on each pipeline; ownership audit with quarterly cadence; five-phase deprecation in place; cost rhythm with the five levers and an accountability owner. Show one representative pipeline on the canvas with every piece wired so the program is reproducible across the rest.
