The Master Experimental Blueprint: Observational Protocols, Benchmark Signals, and Falsification Criteria for the Finite-Capacity Latency–Erasure Theory

We construct the unified experimental and observational protocol paper of the finite-capacity latency–erasure framework and convert the full theory program into an explicit falsification architecture. Earlier FCLET papers established the ontology of bounded realization, the canonical latency field, weak-field corrections, matter coupling, moderated cosmology, stochastic latency noise, thermodynamic closure, compact-object completion, binary timing effects, primordial fluctuation structure, numerical strong-field evolution, quantum-field-theoretic ultraviolet completion, galactic dark-matter mimicry, and finite-capacity entanglement. The present paper gathers these sectoral results into one benchmark matrix and states, in operational form, what experimental teams must measure, where they must look, what signal families the theory predicts, and what outcomes would exclude specific branches or the program’s canonical core. We derive a sector-by-sector blueprint covering precision optical clocks, atom interferometers, pulsar timing, compact-object imaging, gravitational-wave ringdown and echo searches, cosmic-microwave-background low- suppression, galactic rotation benchmarks, and cross-sector parameter consistency. The purpose is not to repeat isolated predictions already given elsewhere, but to organize them into a unified protocol language: observable, instrument class, scaling law, benchmark window, null expectation, finite-capacity deviation, and exclusion threshold. In this way, the finite-capacity framework is no longer presented only as a theoretical architecture. It is presented as a disciplined experimental program. The paper culminates in a falsification matrix that distinguishes between branch-level failure and core-kernel failure. Some observational outcomes would eliminate particular effective descendants while leaving the canonical backbone intact; others would directly violate the central finite-capacity structure itself. This distinction is essential for theoretical maturity. A framework becomes scientifically serious not when it merely accumulates explanatory sectors, but when it states clearly how it survives, how it is constrained, and how it can fail. The result is the final Popper-structured capstone of the FCLET program: a master experimental blueprint that translates finite-capacity physics into a unified measurement agenda.
