Plasticity and Valence Reweighting over Irreversible Residues

CIM v2 (Ishikawa, 2026) formulated the irreversible residue that remains in a self-maintaining boundary as a condition for the generation of qualia, but it did not adequately give form to how that residue is read out into valence and action weight. This paper is an extension that fills this gap. First, it defines transformation (henshitsu) not as the fixed storage of experiential content but as a change—using the irreversible residue as substrate—in the very metric of the evaluation axes, such that the metric does not fully return to its initial state. Second, it positions valence and action weight as modulations read out over that altered metric. The locus of the claim is placed not on the output distribution itself but on the metric that generates the distribution, and its irreversibility is, within CIM, treated as grounded in the terminability of the self-maintaining boundary. This extension does not deny the theory of constructed emotion or engram research; rather, taking as given the history-dependence and plasticity they document, it asks under what conditions transformation is not reducible to a mere updating of the distribution. The scope of this paper is limited to the layer of readout; the origin of qualia and the hard problem itself are left as future work.
