This document introduces pre-detection as a minimal ontological condition prior to irreversible event registration within the Sofience–Δϕ Formalism. While earlier documents in the SΔϕ series established irreversibility as the minimal condition of existence and traced the emergence of subject, interpretation, judgment, authority, and innovation from irreversible re-entry structures, this paper addresses a prior layer: differences that are already operative but not yet detectable within a given interpretive frame. The paper argues that not all operative differences are immediately registrable as events, traces, or historically consequential changes. Some differences remain latent, sub-threshold, or structurally invisible while still shaping later irreversible states. Pre-detection therefore names the state in which a difference is active before it is measurable, speakable, or eventfully acknowledged. On this basis, innovation and rupture are re-described not as emergence from nothing, but as the eventual registration of previously latent difference. In this sense, irreversibility is not the beginning of all structure, but the threshold beyond which latent difference becomes historically consequential. This document is part of the ongoing Sofience–Δϕ (SΔϕ) series, a sequence of minimalist axiomatic papers developing an operational ontology grounded in irreversibility, re-entry, authority, innovation, and structural consequence. This paper extends the sequence of SΔϕ-21 through SΔϕ-24 by introducing the latent layer required to explain how differences become events prior to irreversible registration.
