Invoking Korean War-era emergency powers (Defense Production Act) for critical minerals represents norm erosion in emergency authority scope but falls within established executive practice. Rule_of_law (3.5): stretches emergency powers beyond traditional national security to economic/industrial policy. Separation (4): unilateral executive action bypassing normal legislative appropriations/regulatory process. Capture (2.5): benefits specific mining/industrial interests. Policy_change mechanism with federal scope yields 1.3x and 1.2x modifiers. Precedent severity (1.25) reflects expansion of emergency power justifications. Base calculation: (0×0.22 + 3.5×0.18 + 4×0.16 + 0×0.14 + 2.5×0.14 + 1×0.10 + 0×0.06) × 1.137 × 1.3 × 1.2 = 22.37. B-score: High novelty (5) and media_friendliness (6) for wartime act invocation, pattern_match (5) to emergency power expansion concerns. Layer1: 18.70. However, A<25 and this represents routine if aggressive use of existing DPA authority that presidents have invoked hundreds of times. Classified as Noise despite constitutional concerns because action falls within established executive toolkit and lacks concrete mechanism for lasting damage.
