Quantum Observability under Causal Cloud Cosmology (CCC) Projection-Compressed Manifestation, Residual Coherence, and Local Realization Selection

This work presents a CCC (Causal Cloud Cosmology) interpretation of quantum observability, focusing on interference, measurement, residual coherence, and local realization selection within a continuous global causal structure. Rather than treating quantum measurement as a destruction of underlying possibilities, the framework interprets measurement as a modification of coexistence conditions under realizability constraints. Observable collapse is therefore understood as a locally selected manifestation emerging from constrained observability, while residual coherence may remain globally preserved within CCC structure. Within this interpretation, interference reflects the coexistence of realizable possibilities prior to local observability selection. Which-path information increases realizability constraints and reduces the ability of multiple possibilities to remain jointly manifested within the observable layer. Projection-compressed manifestation is therefore interpreted as an observable consequence of realizability selection rather than a literal elimination of alternative possibilities. The framework provides a unified interpretation for double-slit interference, which-path experiments, weak measurement, entanglement, temporal interference, and wavefunction collapse without altering standard quantum predictions or modern experimental consistency.
