General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
Statutory and effective corporate tax rates, treatment of depreciation, and international competitiveness.
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.
Coalition-government (Conservative + Liberal Democrat) deficit- reduction programme responding to post-GFC fiscal deterioration. Key elements: real-terms cuts to most non-NHS departmental budgets, public-sector pay freeze 2010-2013, corporate tax reduction from 28% to 20% (phased through 2015), welfare reform consolidation (Universal Credit rollout 2013-ongoing, benefit cap), VAT raised to 20% (2011). Debt-to-GDP still rose (inherited debt + slow growth + counterfactual counterfactual). Contested: IFS / Resolution Foundation assessment varies.

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.
