Policy posture toward energy supply security — domestic production capacity, import diversification, strategic reserves, nuclear stance, fossil-fuel mix discipline.
Environmental regulation stringency — emissions caps, standards, phase-out mandates, carbon pricing, renewable portfolio standards.
Security of private property rights — formal recognition, expropriation risk, titling systems.
Reversal of the 2010 lifetime-extension (Laufzeitverlängerung) for German nuclear reactors following the Fukushima Daiichi accident of 11 March 2011. 13th amendment to the Atomgesetz (6 August 2011) immediately shut eight reactors and set phased closure of the remaining nine by end-2022 (extended briefly in 2022-2023 under Russia-gas crisis, final three closed April 2023). Complementary expansion of EEG renewable-feed-in framework. Germany's share of nuclear electricity fell from ~22% (2010) to 0% (2023); gas-and-coal share rose to fill the gap until 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.
