Trade policy openness — tariffs, non-tariff barriers, FTAs, industrial protection.
Targeted industrial and sectoral subsidies (renewable energy, chip manufacturing, agriculture, green hydrogen, etc).
Rule of law as institutional substrate — contract enforcement, judicial independence, equal treatment before the law. Upstream of most other axes.
Zambia joined Angola, the Democratic Republic of the Congo, the United States, the European Union, and development-finance partners in the Lobito Corridor partnership, using the railway and logistics corridor to connect Copperbelt and critical-minerals exports to the Atlantic port of Lobito. The policy aligned Zambian infrastructure planning, border facilitation, and mining export logistics with a multi-country financing and coordination platform.
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.
