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).

The Construir Portugal package of 2024, introduced by the Montenegro AD government under Decree-Law 10/2024 and follow-on measures, rolled back parts of the previous PS "Mais Habitacao" housing reform — restoring the Non-Habitual Resident tax regime in modified form, scrapping the additional IMI on local accommodation, easing rent-control bands, and lifting purchase restrictions on short-term rentals. The intended effect was to reactivate residential investment supply, restore international capital inflows into housing, and reverse what AD framed as anti-investment measures that had constrained construction starts.
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.
