Statutory and effective corporate tax rates, treatment of depreciation, and international competitiveness.
Progressivity of the personal income tax schedule, including top marginal rates, bracket spread, and targeted credits (EITC-equivalents).
General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
Immigration policy openness — work visas, family reunification, asylum processing, border enforcement posture.
Portugal's accelerated NATO defence-spending trajectory, announced by the Montenegro AD government at the July 2024 NATO Washington Summit, committed Lisbon to reach the 2% of GDP defence-spending target by 2029 — earlier than the prior 2030 target — through annual increases in the Defence Ministry budget and acquisition of new air, maritime, and land platforms (F-35 selection, KC-390 fleet, frigates). The intended effect was to align Portugal with NATO's burden-sharing pledge, modernise force structure, and signal Atlantic-alliance commitment amid the post-Ukraine European rearmament wave.
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.
