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).
Taxation of capital income (dividends, capital gains, inheritance, wealth). Distinct from corporate rate.
Canada's COVID-19 fiscal response, anchored by the Canada Emergency Response Benefit (CERB), the Canada Emergency Wage Subsidy (CEWS), and the Canada Emergency Business Account (CEBA), delivered about C$2,000/month to displaced workers, up to 75% wage subsidies to qualifying employers, and forgivable loans to small businesses through 2020–2022. The cumulative federal envelope peaked at roughly 15% of GDP in deficit terms in 2020-21, the largest peacetime fiscal expansion in Canadian history.
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.
