Unlike agent-evals' snapshot-based runtime, this reuses the objects the running
Streamlit app already built (db/reranker from the live Google Docs), so checks
reflect the prompt/KB exactly as deployed right now.

Tool-use scenarios are driven with mock tools that mirror the real tool names and
record every call — no real API needed (works even when ENABLE_TOOLS=0).
