Corpus Scope and Screening Profile
At screening level, the corpus is large enough to establish pattern credibility rather than anecdotal impression. The working review ledger for this chapter records 905 screened records, 498 included after a preliminary conceptual gate, and 129 retained for extraction-level analysis. This yields a post-screen extraction ratio of 14.3 percent and a post-preliminary extraction ratio of 25.9 percent. Excluded records total 776 relative to the screened pool. Evidence rows extracted for synthesis coding total 810. The screened and extracted sets remain cross-domain rather than domain-monolithic, with strongest concentration in biology, engineering, computer science, and management. That spread is what enables cross-domain definition synthesis.12 Overall, the corpus profile confirms that the cross-domain modularity definition synthesis in Chapter 2 rests on a sufficiently large and methodologically filtered evidence base to support the frame-dependent modularity claim that the thesis advances. Therefore, the domain distribution documented here — with evolutionary biology, product design, and computer science as the primary concentrations — establishes that the synthesised definition is grounded in the fields from which the thesis’s theoretical framework draws its key modularity precedents.
