Notation

This part uses the salient coordinates of Parts I–II: five world-axes — $\valence$ (valence), $\arousal$ (arousal), $\intinfo$ (integration), $\effrank$ (effective rank), $\mathcal{CF}$ (counterfactual weight) — and an entity-directed salience family whose diagonal is self-model salience $\mathcal{SM}$, split into $\sigma_{\text{attention}}$ (self as object of attention) and $\sigma_{\text{causal}}$ (self as driver of action). Not a fixed six but an extensible set; the affect state $\mathbf{a}_t$ is characterized by whichever coordinates the phenomenon makes relevant. Cultural forms, practices, and technologies have affect signatures—the structural features they reliably modulate. The perceptual mode through which a signature is felt runs not on one scalar but three independent axes (Part II): $\alpha(x)$, the entity-indexed ascription field (how much interiority, agency, teleology the system grants entity $x$); $\kappa$, the coupling of the perceiver's own modes (perception, affect, agency, narrative — high $\kappa$ is the curved eigenskeleton felt as "meaning," low $\kappa$ the flat skeleton where the world goes dead); and $\gamma$, the gain or precision weighting that sets how far bottom-up signal overrides top-down prior. That these three covary in biological perceivers is a conjecture, not a definition.
