7.1 Clinical Boundary

Human FBM is structural nutrition language, not a diagnostic system, and not medical care.

When disease, acute symptoms, severe metabolic disturbance, or medically supervised states appear, structural backtrace should stop and the case enters clinical boundary.

Acute symptoms, rapid weight change, and severe metabolic disturbance are clinical-boundary signals.

Marked liver-kidney dysfunction, pregnancy, and lactation are clinical-boundary contexts.

Chronic disease management requiring medical supervision cannot use generic structural pages as sole interpretation layer.

At clinical boundary, structural variables may still be recorded but are no longer the sole explanatory layer.

Structural language can provide background understanding but cannot replace medical supervision.

Under clinical boundary, outputs may be highly volatile and difficult to explain with single-substrate variables.

Stopping structural backtrace prevents complex clinical states from being reduced to diet-structure adjustment problems.

This page provides no diagnostic conclusion, no medical-care promise, and no outcome guarantee.

Structural nutrition language and clinical management must remain layered.
