Japanese National Railways Reform Law (28 Nov 1986) broke JNR into six regional passenger companies (JR East, JR Central, JR West, JR Hokkaido, JR Shikoku, JR Kyushu) plus JR Freight and JR Bus, effective 1 Apr 1987. JNR Settlement Corporation absorbed JPY25.5tn of JNR's accumulated debt. JR East IPO Oct 1993, JR West Oct 1996, JR Central Oct 1997. Retrenchment cut ~200,000 jobs; shinkansen and urban services achieved profitability.
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.
