Sector-specific licensing regimes, concentration / quota allocation, state-controlled entry (energy, telecoms, healthcare, banking).
Targeted industrial and sectoral subsidies (renewable energy, chip manufacturing, agriculture, green hydrogen, etc).
Trade policy openness — tariffs, non-tariff barriers, FTAs, industrial protection.
General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
France's accession to the European Economic Community via the 1957 Treaty of Rome committed Paris to a customs union, common external tariff, and progressive elimination of internal trade barriers among the original six member states. Ratification embedded French agriculture, industry, and services into a supranational regulatory and subsidy framework (later the CAP) and locked in tariff liberalisation alongside continued sectoral planning at home.
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.
