Roh Tae-woo's Nordpolitik foreign-policy doctrine extending 1988 Seoul Olympics legitimacy gains into diplomatic normalisation: Hungary (Feb 1989), Poland (Nov 1989), USSR (30 Sep 1990), North- South Korean Basic Agreement (13 Dec 1991), Joint Declaration on Denuclearization (20 Jan 1992), China (24 Aug 1992).

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.
