Assemble the end-to-end capstone pipeline

Stakeholders want one scheduled workflow that pulls weather, normalizes it, skips duplicates, batches the rest, checks quality, and separates clean results from failures — the full toolkit from this chapter on one canvas.

Build it from scratch: Schedule Trigger and HTTP Request for data ingestion, Code nodes for transforms and deduplication, Loop Over Items for batching, then an evaluation gate with If to split pass/fail outcomes.
