Definition
The answer tells you what; confidence tells you whether to act. A common starting pattern divides confidence into three ranges: high confidence acts automatically, medium confidence proceeds with confirmation or review, and low confidence does not act at all.
Gates appear throughout the docs and cookbooks: a 0.7 escalation gate in the SDE cascade, a 0.8 auto-accept gate for citations, a 0.6 floor in voice banking. The values are policy, so start conservative, test on your own data, and adjust.

Use the answer to decide what to do and confidence to decide whether to act: the voice-banking example routes below 0.6 to a human and needs 0.85 or more to auto-approve a transfer.
