Routed urgent or low-confidence extracted fields to a human loop using the runtime StartHumanLoop client and a flow-definition ARN. Integration was coded and unit-tested with mocks only; no live review loop was started.
- What worked
- A single start-loop call plus flow definition config was enough to attach clinical review after extraction without replacing the index processor.
- What got in the way
- Finding the correct runtime Maven artifact and StartHumanLoop request shape required extra search; human-loop lifecycle beyond the start call was not exercised.
