Independence of the judiciary from executive and legislative encroachment. Specifically captures court-packing, selective prosecution, judicial reshuffles.

National Assembly impeached President Roh Moo-hyun on 12 March 2004 (193 votes to 2 in mostly-boycotted Grand National Party + MDP session) on charges of violating Election Law neutrality (supporting Uri Party pre-election) and incompetence related to economic management and corruption allegations against aides. Prime Minister Goh Kun served as acting president 12 March - 14 May 2004. Constitutional Court ruled 14 May 2004 that while Roh's election-law violation was technically proven, it was not grave enough to warrant removal; impeachment dismissed and Roh resumed duties. Uri Party won April 2004 National Assembly election 152/299 seats in backlash against impeachment. Episode established Constitutional Court's final-arbiter role on presidential impeachment.
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.
