The Single European Act, signed in 1986 and entering into force on 1 July 1987, was the first major revision of the EEC treaties since 1957. It set a binding deadline of 31 December 1992 for completing the internal market with free movement of goods, services, capital, and persons, replaced unanimity with qualified-majority voting on most single-market measures, and constitutionalised the broader programme set out in the 1985 Cockfield White Paper (COM(85) 310).
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.
