Rule of law as institutional substrate — contract enforcement, judicial independence, equal treatment before the law. Upstream of most other axes.
Joint press announcement by Foreign Ministers Yun Byung-se (Korea) and Fumio Kishida (Japan) on 28 December 2015 declaring a "final and irreversible" resolution to the wartime military-sexual-slavery ("comfort women") issue. Included Prime Minister Abe's apology of "deepest remorse" conveyed via Kishida, a ¥1bn (~$9m) Japanese government contribution to a Korean-administered Reconciliation and Healing Foundation for surviving victims (46 living at time of agreement), and mutual commitment to "refrain from accusing or criticising each other" in the international community. Controversial domestically in Korea for bilateral nature excluding victim participation; Moon Jae-in administration dissolved the Reconciliation Foundation November 2018 while noting the agreement itself was not formally revoked.
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.
