Trade policy openness — tariffs, non-tariff barriers, FTAs, industrial protection.
Rule of law as institutional substrate — contract enforcement, judicial independence, equal treatment before the law. Upstream of most other axes.
EU-Turkey Association Council Decision 1/95, signed 6 March 1995 and entering into force 1 January 1996, established a customs union covering industrial goods and processed agricultural products (excluding primary agriculture, services, and public procurement). Turkey adopted the EU Common External Tariff and aligned on commercial policy, competition law, and IP protection. At the time it was the deepest non-member EU economic tie.
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.
