This paper introduces the Qualion as a minimal unit of translation underlying both physical and experiential descriptions of consciousness. The Qualion is independently derivable along two non-reducible methodological paths: (A) a transcendental analysis of the conditions required for any ontological description to be possible, and (B) a phenomenological reduction to the lower bound of conscious experience. Despite their methodological independence, both paths converge on the same formal structure, expressed as an ordered triple (S,R,D): a state space, a response function, and a persistence condition. This convergence is argued to be analytically necessary rather than empirically contingent. Physical and experiential accounts are reconceived not as ontologically distinct kinds, nor as reducible or emergent relations, but as dual translation modes of a single response-structural process. To explain why some systems support experiential description while others do not, the paper introduces translationclosure integration Ψ as a structural threshold condition for internal (experiential) mode. Situated at the intersection of phenomenology and cognitive science, the framework draws on the neurophenomenological program of Varela and Thompson while proposing a structural bridge between firstperson phenomenological analysis and third-person empirical description. The paper offers a novel approach to the explanatory gap by reframing the presupposed ontological divide between mind and matter as a descriptive asymmetry rooted in the structure of translation itself.
