Alea
A Jev/System One-inspired decision model: given a shared state and a set
of typed questions, returns bounded probabilistic answers in one
forward pass — no autoregressive generation.
Backbone: Qwen3-0.6B (bidirectional via a custom 4D mask) + ISAB
set-attention readout heads. Primitives: choice (categorical dist),
noul (Bernoulli), score (ordinal dist), regress (19 monotone
quantiles). Option-order permutation invariance and question isolation are
exact by construction.

training roadmap + metrics ledger.
