Dark launch

Ship new behavior to production **hidden from most users** — often via feature flags at 0–5% traffic.

#When to use

Test a new RAG index or agent tool with real traffic before announcing it.

#When not to

When you have no metrics or kill switch — fix observability first.

#Example

Enable `new_retriever_v2` for internal staff accounts only while dashboards watch groundedness.
