Immigration policy openness — work visas, family reunification, asylum processing, border enforcement posture.
Lag (2016:752) om tillfälliga begränsningar av möjligheten att få uppehållstillstånd i Sverige, in force 20 July 2016 in response to the 2015 asylum peak of ~163,000 claims. Switched permanent residence permits to three-year temporary permits for subsidiary-protection and Convention-refugee status, tightened family reunification, and aligned Sweden with EU-minimum asylum standards — the sharpest single-year restriction of Swedish migration policy in the post-war era. Made permanent via Utlänningslag amendments in 2021.
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.
