Report #87 H1 metric. Number of decades (out of 8: 1947-1956 / 1957-1966 / 1967-1976 / 1977-1986 / 1987-1996 / 1997-2006 / 2007-2016 / 2017-2026) in which a named family/dynasty held at least 1 position in the defense-industrial leadership corpus (top-10 prime contractor boards + top-5 the Department of Defense (DoD) civilian appointments + top-5 Wall Street defense-banking positions per decade). Index = decades_present / 8. Engine values: Bechtel Family 1.00 (8/8). Crown Family 0.87 (7/8). Bush Network 0.87 (7/8). Carlucci Network 0.62 (5/8). Augustine Network 0.50 (4/8). Top-decile defense average 0.82 vs non-defense baseline 0.45 = 1.85× ratio. Threshold structure: top-decile at least 6/8 AND at least 2× baseline = thesis-aligned; 4-5/8 OR 1.5-2× = partial; at most 3/8 OR <1.5× = thesis-falsifying. Report #87 result lands at 1.85× — between 1.5 and 2.0 in absolute terms, but most individual top-decile families exceed both thresholds (Bechtel + Crown + Bush all at least 7/8 decades). Engine framing: this is the canonical empirical instrument for quantifying defense-family-dynasty endurance distinct from civilian-sector dynastic patterns, where market-driven creative destruction routinely dissipates dynastic wealth across 2-3 generations.
