Policy posture toward energy supply security — domestic production capacity, import diversification, strategic reserves, nuclear stance, fossil-fuel mix discipline.
Rule of law as institutional substrate — contract enforcement, judicial independence, equal treatment before the law. Upstream of most other axes.
Finland's accession to the North Atlantic Treaty Organisation, ending 75 years of military non-alignment that followed the 1948 Finno-Soviet Agreement of Friendship, Cooperation and Mutual Assistance. Application submitted jointly with Sweden on 18 May 2022, nine weeks after the Russian invasion of Ukraine. Ratified by the Eduskunta 1 March 2023 (184-7); accession instruments deposited in Washington 4 April 2023 making Finland the 31st Ally. Extended NATO's direct land border with Russia by 1,340 km. Complemented by a bilateral Defence Cooperation Agreement with the United States signed 18 December 2023, authorising US access to 15 Finnish military sites. Policy initiated under the Marin government and completed under the Orpo government with very broad cross-party consensus; public support for NATO membership shifted from 20-30 percent pre-invasion to 75-80 percent by April 2022.
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.
