Based on the SFL theoretical framework & G₀ fixed architecture principle derived from previous serial papers, this paper reanalyzes the origin formation rule of viruses and supplements the origin constraint logic consistent with the unified complex system theory of SFL-EAI series. Traditional paleovirology hypotheses generally hold that viruses gradually assembled and evolved from simple organic substances or primitive microorganisms over long geological periods. Combining the bounded variation and genetic damage conclusions concluded in SFL-VIR-01 to SFL-VIR-04, this study proposes that every virus carries a complete and closed initial genetic architecture G₀ at its initial formation stage. All trait differences recorded in viral evolutionary pedigrees are merely phenotypic deviations produced by later cumulative genetic damage ΔGd, rather than spontaneous generation of brand-new core genetic frameworks or novel viral categories. Combined with the unified system state equation: G=G₀+ΔGd (+) -ΔGd (-) In accordance with the universal dissipation stability constraint of complex systems: ε (T) =o (1 / T) Logical deduction verifies that long-term time accumulation, environmental changes and repeated genome replication cannot rewrite the inherent G₀ core framework of any virus. Minor trait deviations accumulated over time cannot splice complete new viral structures. Ancient viral residual gene fragments and modern pathogen monitoring data both support the fixed-origin characteristic of viral groups: all viral taxa originate from preset intact G₀ structures, instead of gradual evolutionary assembly from simple precursors. This origin rule keeps isomorphic consistency with the fixed initial design rule of biological cells, electronic circuits and AI core algorithms in SFL serial researches, perfecting the unified origin constraint of all stable complex systems.
