With liquid flash systems, jobsite damage can be repaired by applying liquid flash to that specific spot, whereas with other products damage (e.g., a ladder dropped against wrap) creates a permanent weakness that allows water penetration and spreading damage below

Capillary action pulls water through fastener penetrations and into house wrap materials when pressure is applied, which is why cap fasteners that break capillary action perform better than plain staples

Jordan emphasizes that proper installation is a major tricky part of waterproofing: getting details right around windows, doors, and penetrations requires careful execution, and this is where stapled products make it difficult because they don't stick and require complex 'origami' to get details right

China policy in the early 1980s under Deng Xiaoping's economic opening was the 'height of this discussion'—the moment when Taiwan unification seemed most plausible—because China was at its most liberal point; for any future Taiwan unification scenario to succeed, China would need to evolve in a more liberal direction, not toward greater coercion.

From an elite-politics-dynamism perspective, the current era is a 'nadir' compared to earlier decades: Xi's big-bang consolidation is over and leadership, PLA modernization, and economic reform are all in cruise control, even as China is more powerful as a share of global national power than ever before.

Xi will be disinclined to move to the 'second line' (the late Deng model) and will instead try to push off dealing with succession, leaning toward the Mao model, because he has two historical examples of succession going badly, a cult of personality, and a belief that he is indispensable—making a voluntary step-back a low-probability event absent real health issues.

Potential successors without real PLA connections (like Hua Guofeng, Zhao Ziyang, and Hu Yaobang historically) failed to stick; because Xi is preventing any party figure from developing those military connections, it will be very hard for any future successor to consolidate.

Xi's analysis of younger potential successors faces a hard information problem because he lacks personal relationships with people in his age cohort's children's generation, unlike US presidents who blend one or two close associates with many professionals—Xi's Standing Committee is uniquely composed almost entirely of decades-long friends.
