A quiet nebula around a core tone — weighing every experience against an unargued inner compass.
Zone B · stack position
The canvas draws Fi as a nebula around a core: every experience that enters is weighed against one inner tone. Where Fi sits in a person's stack — the fixed order their eight functions come in — changes how that weighing runs. Click a position to see the change, and drag the maturity slider to watch the lower seats gain fidelity with age.
Loading description…
With age, lower stack positions gain fidelity, duty cycle, and structural complexity.
Zone C · feeder coupling
Fi judges; it does not gather. A perceiving function — its feeder — has to deliver the experiences it weighs, and which one does the delivering changes what the weighing builds. Click a feeder to watch the nebula change shape and motion.

Zone D · verification lab
Watch Fi weigh experiences against its one inner standard in real time. Each button sends in a different kind of event — true joy, true grief, flattery, a violation — and the meters track what each one costs.
Zone E · field notes
Patterns from the wild — how Fi shows up in daily life.
