General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
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.
Progressivity of the personal income tax schedule, including top marginal rates, bracket spread, and targeted credits (EITC-equivalents).
$1.9 trillion pandemic fiscal package passed via reconciliation on party-line Democratic vote. Core components: $1,400 per-person direct payments; extension and $300/week top-up of federal unemployment insurance through September 2021; fully refundable and expanded Child Tax Credit for 2021 (monthly advance payments, up to $3,600 per child); $350bn State and Local Fiscal Recovery Funds; $123bn K-12 Elementary and Secondary School Emergency Relief; expanded ACA premium subsidies; expansion of EITC for workers without children; rental assistance, SNAP extensions, vaccine and testing funding.

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.
