Four Theta Moment Intervals Close the First Cubic Gate
Directed enclosures of the four completed-theta moments prove
0.3605445479650506<C3<0.3605445479659221,
and place the source on the low-reserve branch through the rational bound
Q(C3/7)<0.9351102213017192<1.
The cross-multiplied global-flux numerator has strict lower bound
Z43Z2−Z5Z33>5.88147833916049×10−17,
and the complete algebraic lower-gate gap satisfies
C3C4−(3C3−7C4)2>0.1384003865828292.
Thus the first hostile cubic theta interface passes by positive completed
variance flux rather than by a large static reserve.
