Uncertainty is a measurement, not a disclaimer.
A point forecast tells a decision-maker what a model believes. An interval, a stress case and a validity horizon tell them how much that belief is worth. Decision-grade inference keeps all of them visible.
Why conventional approaches fail
Precision is easy to manufacture.
A model fitted closely to historical noise produces narrow bands and confident alerts. Neither survives contact with a new sample or a changed regime, and the decision-maker has no way to tell the difference from the output alone.
Grand Thera treats uncertainty as a first-class output. Every inference carries its interval, the conflict that remains unresolved, its robustness under perturbation and the horizon after which it is stale.
One stream, three readings
From raw information to decision-relevant evidence.
Persistence
A signal must survive being challenged.
Within one model family the question is not whether it detected something, but whether the decision-relevant property persists when reasonable analytical choices change.
Four distinct outputs
Different questions deserve different numbers.
Calibrated probability
How often events like this one actually occur when the model says p. A frequency-honest target, checked against realized outcomes.
Fuzzy membership
How closely the current state resembles a defined condition. A degree of resemblance, not a probability, and never presented as one.
Stress response
How the conclusion moves under an adverse but plausible scenario. Sensitivity, not likelihood.
Calibration status
Whether the probabilities have recently been honest. A diagnostic of the model, not a measure of confidence in the event.
Computational epistemology
No single score can replace interval, conflict, robustness, horizon and lineage.

Ontology structures what is available to the machine. Computational epistemology structures what the machine is permitted to conclude from it.
