This technical note clarifies the conceptual architecture linking a distributed set of previously published records on interface-mediated observability, contextual clockability, non-invertibility, inferential residuals, and regime-dependent limits of global closure. Rather than introducing new dynamics or new ontological commitments, the note makes explicit a common structural perspective that was previously distributed across diagnostic and methodological works developed in different domains. The central claim is methodological: scientific descriptions are not only theory-dependent, but also constrained by the structure of the interfaces through which information becomes observable, by the reductions through which it is processed, and by the conditions under which traces remain comparable across contexts. Within this perspective, three recurring structural conditions become central: limits of manifestation, arising from interface-mediated access and possible non-invertibility; limits of global closure, arising when locally valid descriptions cannot be fully integrated into a single globally coherent account; contextual comparability, arising from the requirement that traces be sufficiently stable, accessible, and mutually comparable to support temporally ordered description. This record makes explicit that a number of previously published diagnostic notes are not isolated case studies, but parts of a coherent structural research program on the limits of scientific description.
