M4 extends the M3 response + response-time + gaze + pupil measurement backbone with a sequential latent response-process state. The state is a statistical configuration of process measurements, not a psychological construct.

sim <- simulate_multimodal_m4(n_person = 30, n_item = 8, seed = 20260820)
spec <- multimodal_m4_spec(n_states = 2, trait_conditioning = c("theta", "tau"))
print(spec)

The reference scored-response model remains state-independent. States shift RT, gaze, and pupil process channels only, and posterior state probabilities are the primary inferential object.
