Read the flagship's feature table from a free-tier warehouse; no new infra.
1. What to do
Create the free-tier project, load the starter CSV (or query the sample dataset), run the 3 provided read queries (row counts, null audit, one join), and save the query history as evidence.
2. Why reads, not pipes
The flagship trains from versioned files; the warehouse lesson proves you can read governed tables (types, partitions, quotas) without owning a pipeline. Full ingestion pipelines stay in the DE track.
3. Quota guardrails
Free-tier query caps per month; always preview (LIMIT, dry-run bytes) before
full scans. Log bytes-billed per query in the flagship appendix.
