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.
Advisory referendum 23 March 1980 on Sweden's nuclear-power future. Three lines: Line 1 (Moderate) 18.9% for continued expansion; Line 2 (SAP+Liberal) 39.1% for 12-reactor completion then phase-out; Line 3 (Centre+Communist) 38.7% for immediate phase- out. Parliament interpreted the Line 2 victory as mandate to run the 12 reactors for ~25 years then close — a commitment Sweden later partly reversed.
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.
