Immigration policy openness — work visas, family reunification, asylum processing, border enforcement posture.
Legge 30 July 2002 n. 189 ("Bossi-Fini") tightened Italian immigration law: residence permits tied to employment contracts (permit expires with job loss); required fingerprinting of non-EU applicants; expanded expulsion procedures; shortened permitted durations; restricted family reunification. Also included a concurrent regularisation of 700,000+ undocumented domestic and care workers.
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.
