Warehouse Reads (BQ/Snowflake Free Tiers)

# Warehouse Reads (BQ/Snowflake Free Tiers) 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.
