Belief-Register Update

Canonical definition

The event in which the posterior a Ground-Resolution cycle returns is written into the Belief Register. The write is Ground-Resolution's output rather than a further operation performed on it; there is no step between resolving and storing. Once written, the posterior becomes the prior for the next Ground-Resolution cycle and the template the Observer reads on its live salience-computation pass. Habit-timescale action-selection is driven by the cached-value (habit) store intrinsic to the Decision Hub, acted on directly; that store is distinct from the Belief Register, which the Observer reads for salience-conditioning. Only the Thinker writes to the Belief Register. The Observer and the Decision Hub are read-only with respect to the Belief Register: they read what the Thinker has committed, and they have no mechanism to write to it. This asymmetric read-write structure is load-bearing: it means that insight does not translate immediately into changed behaviour. Before a revised deliberative posterior propagates downstream, the Thinker must perform a sufficient number of Belief-Register Updates to move the Belief Register’s stored posterior close enough to the revised deliberative posterior for the Observer and habit-selection to track the revision. The number of Updates required depends on the magnitude of the revision and the slow-layer parameters governing the replicator-Bayes operator (Appendix A.5.6). Repeated Updates over time is the architectural basis of the insight-behaviour lag formalised in the Adoption-Action Distinction.
