The engine decides. The model describes.
No finding in this system originates from a language model.
Measurements, findings and severity are produced by a versioned deterministic rule engine reading the stored samples. A language model is used only to turn validated findings into readable prose — it is never asked what the ECG shows, and a statement it produces that is not traceable to a validated finding is a defect.
Quality is a gate, not a footnote.
An uninterpretable recording produces no interpretation, not a cautious one.
Automated interpretation is published only when the recording passes quality validation. Where it does not, the result is the explicit statement that interpretation was withheld — which is a different thing from a normal ECG, and is presented as such.
A person is in the loop, by permission rather than by habit.
Review, override and sign-off are separately permissioned acts, and disagreement is recorded.
A signature is bound by digest to the exact interpretation it covers and to the person who gave it. An override is stored as an override for ever: the automated finding, the clinician’s finding and the reason, all attributable.
Nothing is asserted without the evidence for it.
Every claim on this site about a capability maps to something the software does.
The limits stated on these pages are not modesty. Automatic renewal, email delivery, invoices and refunds are genuinely absent, and the product reports them as absent in its own health probe rather than leaving them to be discovered.
