carrier noise
Static contains several weak correlated structures; attention, motion, and time change which one crosses the threshold from noise into evidence.
surface
Only static is visible and audible.
disturbance
Stillness integrates one weak correlation while movement reveals another; touching compresses entropy locally before noise takes the field back.
recognition
Signal and noise are not permanent categories. A relationship can become evidence only after the observer supplies enough integration.
system
Layered procedural noise, temporal accumulation buffers, matched visual/audio spectra, band-pass filtering, and optional model confidence as a hidden influence.
