Central Government Reform effective 6 January 2001 consolidating 22 ministries and agencies into 12 ministries (plus Cabinet Office). Strengthened Cabinet Office with Council on Economic and Fiscal Policy (CEFP), Council for Science and Technology Policy, and Gender Equality Bureau. Created Ministry of Land, Infrastructure and Transport (MLIT), Ministry of Education, Culture, Sports, Science and Technology (MEXT), and Ministry of Economy, Trade and Industry (METI, ex-MITI). Designed to strengthen political leadership over administrative ministries ahead of the Koizumi-era reform push.
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.
