Rule of law as institutional substrate — contract enforcement, judicial independence, equal treatment before the law. Upstream of most other axes.
Political dissolution of the CD&V-N-VA electoral cartel on 21 September 2008, removing the Bart De Wever flemish-nationalist current from governing Christian-democratic cooperation. Set up the post-2010-election N-VA surge that produced the 541-day government-formation crisis and the 2014 Suédoise coalition. Not a policy in the narrow sense but a political institutional structural shift with persistent policy consequences for Belgian federalism and state reform.
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.
