22 Jan 1990 merger of President Roh Tae-woo's Democratic Justice Party (DJP), Kim Young-sam's Reunification Democratic Party (RDP), and Kim Jong-pil's New Democratic Republican Party (NDRP) to form the Democratic Liberal Party (DLP) on explicitly Japanese-LDP conservative-coalition template. Created 218-seat parliamentary supermajority enabling labour-law and fiscal reforms; fractured Korean opposition between Kim Young-sam (now ruling) and Kim Dae-jung (PDP opposition).
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.
