This paper formalises Tier-4 observation as a constrained interface within the Paton System. Observation is shown to be a bounded representation of admissible structure rather than direct access to the full system. Across both scale and tier, structure is transformed under constraint, producing limits of resolution and legibility. The observable region is defined as a constrained window in which structure becomes partially legible, while beyond this region structure remains inaccessible due to resolution limits or compression under constraint. This establishes observation as a local interpretive interface rather than a central or global perspective.
