STYXX
the live signature
A real model's geometry of meaning, reacting in real time to its own internal state. The constellation is gemma-2-2b's 96 measured concepts. As styxx reads 32 real statements through the model's layer-12 truthfulness probe — before a single token is generated — grounded statements keep the field calm and cyan; ungrounded ones ignite the red signature. The probe is right about three times in four on these fresh facts, and its misses are shown honestly. This is an instrument with a stated operating range, not a polygraph.

GROUNDED
internal grounding
real activations · truthfulness probe 0.75 on fresh facts · calibrated signature, not a verdict
constellation: gemma-2-2b's norm-equalized concept geometry (96 concepts, PCA-3D, real cosine edges).
signal: styxx layer-12 truthfulness probe, read from the residual stream before generation — a calibrated in-distribution correlate of believed-truth, not a universal lie verdict.
