C.43:4.1.2 - Explain controlled self-change through its acting and changed sides

A continuation can change the means of later control: a model used for interpretation, a policy, a performer’s capability, an allocation of work or the controlled system itself. Identify what is changed, what makes the change, why this intervention is selected or triggered, and how it alters later action. Then connect the resulting observations to the decision to retain, revise or undo that change where those alternatives are available. This extends the same account to changing control arrangements without assuming that their mechanism remains fixed.

Use A.12 to recover the acting participant and changed subject. Its Reflexive Split applies when both are distinct actual entity parts or subsystems of one containing holon, with established parthood. Shared hardware does not require that their functional contributions collapse, while different roles or successive versions alone do not establish different entity parts. An ordinary account can retain the demonstrated action and change when that stronger internal-parts claim is not available.

Reflexive Split answers who acts on what inside the whole. The control explanation additionally connects the change to its regulating rule or intended result and to the consequences for subsequent work. A perfectly identifiable updater can install an unsuitable setting. Temperature drift can alter the same device without being the intervention selected to obtain that result. Random generation of candidates can be part of controlled search when the generation, examination and retention of variants form the actual arrangement; determinism alone does not establish such an arrangement.

For adaptation, distinguish updating the estimate of the current situation, changing an estimated model, adjusting the controller and changing the actual subject dynamics. Direct adaptation can adjust controller parameters without first constructing a new plant model. When a property depends on those parameters, examine the combined operation of acting and updating under the conditions of the claimed property. A result for a fixed setting answers that fixed-setting question; the technical Method must establish which updates preserve it. Development adds the further question of changed attainable problems and means, developed in §4.8.
