We propose a unified reinterpretation of three phenomena usually treated separately—particle production from the vacuum, decoherence,and Hawking radiation—within the framework of Bulk–Brane theory, in which observable physics emerges as a regime of readability ofcompatible configurations within a finite band. We show that these phenomena can be interpreted as variations of a single operational quantity: band accessibility. The emergence of states corresponds to an increase in readability, while decoherence and Hawking radiation correspond to a loss of access and closure of the constraint.Hawking radiation is derived as an effect of exponential loss of matching, in which the thermal factor naturally emerges from a loga-rithmic singularity of the operational coordinate, producing a Planckian spectrum without postulating ontological particle creation.The framework is compared with experimental data. Spin corre-lations of ΛΛ̄ pairs measured by the STAR Collaboration exhibit adecay compatible with a reduction of accessibility. In contrast, strong lensing time-delay data from H0LiCOW/TDCOSMO show no statis-tically significant improvement over the standard model, indicating that possible band effects are subdominant at current observationalprecision. Measurements of cosmic birefringence from Planck PR4 and ACT DR6 are compatible with a cumulative phase interpretation ofthe readability function, but are not discriminative with respect to alternative physical interpretations or systematic effects.These results do not constitute a verification of Bulk–Brane theory, but show that it provides a coherent structural grammar connectingvacuum phenomena, information, and emergent gravity within a single operational scheme.
