Rule of law as institutional substrate — contract enforcement, judicial independence, equal treatment before the law. Upstream of most other axes.
Independence of the judiciary from executive and legislative encroachment. Specifically captures court-packing, selective prosecution, judicial reshuffles.
On 6 Oct 1976, one month after Mao's death, Hua Guofeng with support from Marshal Ye Jianshuai and Wang Dongxing ordered the arrest of the Gang of Four — Jiang Qing, Zhang Chunqiao, Yao Wenyuan, Wang Hongwen — ending Cultural-Revolution-era mass-mobilisation politics. Ten-million-signature 1980-1981 show trial handed death sentences (commuted). Not an economic policy per se but the institutional pivot enabling subsequent economic reform.
Per invariant 3, reforms are scored by what they did on each channel-separated axis, not by the party that enacted them. This fingerprint is how the policy-match engine finds historical analogues.
Explicit links are curated by the author. Inferred links are hypotheses in the library that test the same axes this policy moved — the framework's answer to "what does the data say about a policy like this?".
Ranked by axis-fingerprint overlap with this policy. Direction match bolded — those are the closest historical analogues. Shape of the match is what drives policy-outcome comparison, not the country or party label.
