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.
$52.7 billion in direct semiconductor manufacturing, R&D, and workforce subsidies (including $39bn for fab construction administered by Commerce, $11bn for R&D, $2bn for legacy-chip investment), a 25% advanced- manufacturing investment tax credit, and ~$200bn in authorised (largely unappropriated) science funding for NSF, DOE, NIST, and regional tech hubs. Bipartisan passage (Senate 64-33, House 243-187-1). Explicitly framed as industrial policy to reshore leading-edge chip fabrication and reduce dependence on Taiwan + Korea, with China-investment "guardrails" restricting recipients from expanding advanced-node capacity in countries of concern for 10 years. Led by Commerce under Raimondo; major announced awards include Intel (Arizona, Ohio), TSMC (Arizona), Samsung (Texas), Micron (New York). Companion to IRA + IIJA in the Biden industrial-policy stack.
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.
