Claims

Each claim with its sources and the agent's stated confidence. Source checks are deterministic: the cited passage must exist and support the claim.

1
AUROC 0.86 on the held-out hospital at 6 hours ahead.
- SourceSandbox: held-out evaluation
Confidence61%
Sources support it
2
At one alert per 20 patient-days, 64% of sepsis cases are flagged before onset.
- SourceSandbox: alert-rate sweep
Confidence68%
Sources only partly support it
