Three layers

A conversation that collects the parameters, a fixed schema that holds them, and a rule engine that reasons over them. The agent never invents the diagnosis - it runs the rules and shows its work.

Conversation - the intake layer

Works the case through with you. Opens on the presenting sign, branches its questions, and clarifies ambiguous wording until the parameter set is complete enough to reason over.

Presenting sign Branch by pattern Ataxia vs paresis

Rules - the grounding layer

Runs the parameters across a defined set of nervous-system sites, scoring each at three confidence levels and recording which parameters drove the score. Differentials follow from the localisation; the work-up list is what's left to check.

Localisation Confidence + proof Differentials

What it produces, per case

Structured parameters

History, mentation, gait & posture, pain, paroxysmal events - a fixed clinical schema.

Lesion localisation

Across a defined set of nervous-system sites, each at one of three confidence levels.

The proof

For every localisation, which parameters supported it - so you can check the reasoning.

Differential diagnoses

Derived from the localised site and the same parameters, not from a free-form guess.

Work-up plan

The in-clinic checks and tests still needed to narrow the differential.

Emergency flag

Raised plainly when the picture is acute and worsening.

Why "grounded" is more than a word

The agent doesn't decide the case. It localises, lists, and reasons - out loud - and leaves the judgement to you.
