name	ccd-cognitive
description	Scalar active inference on case diagrams — beliefs, variational free energy, belief updates, prediction error, EFE, N400/P600 proxies. Use for §7; use src.daif for distributional returns and full ERP pipeline (§7c).

When to use

• Scalar (single-distribution) FEP quantities: KL / variational FE, Bayesian belief updates, precision-weighted PE, expected free energy, simple ERP amplitude proxies.
• Not for full return distributions, quantile TD, or Bethe/VMP blocks — those live in daif/.
