Size of cash and near-cash transfer programmes (unemployment benefits, means-tested assistance, universal child benefits). Architecturally distinct from forced-saving schemes — see condition welfare_architecture.
General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
Rule of law as institutional substrate — contract enforcement, judicial independence, equal treatment before the law. Upstream of most other axes.
Trade policy openness — tariffs, non-tariff barriers, FTAs, industrial protection.
The DPJ's Individual Household Income Compensation Programme for farmers, launched in fiscal 2010, paid direct income transfers to producers of rice, wheat and other staples to cover the gap between standard production cost and average market price. It replaced parts of the prior price-support and acreage-set-aside regime with a direct-payment system, fulfilling a 2009 manifesto pledge to support household incomes in agriculture.
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.
