RAG Best Practices
A cost-ordered ladder of fixes that says what each rung forces you to redo, how to ship a query-time change and cut over an index you can roll back, launch gates written as tests, and the levers that cut latency and cost.

After this section you can
- Choose the rung that fixes the gate which lost the chunk, cheapest first
- Ship a query-time change behind a flag, with a canary and a rollback
- Write each launch gate as a test, and price a change at list prices

RAG Best Practices
When answers are wrong, which fix to try first, how to ship it safely, which tests must pass before launch, and what the bill and the latency depend on.
Key idea
A wrong answer has a gate that lost the right chunk, one of five checks in RAG Architecture. Climb the fix ladder from the cheapest rung that gate allows, ship one rung per release behind a flag, and ship nothing until its launch gates pass as tests.
Climb from the cheapest rung, and prove each one before it ships
