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.
Second-term Blair government committed to matching EU average health spending share of GDP, implemented via NHS capacity expansion (NHS Plan 2000). Public-sector headcount grew substantially. Working Tax Credit + Child Tax Credit expanded (2003). Sure Start children's centres. Large absolute increase in public spending as % of GDP (~37% in 2000 to ~48% in 2009 — partially crisis-driven). Critics distinguish pre-crisis deliberate expansion from 2008-2009 automatic-stabiliser + crisis-response component. Forward-referenced policy from uk_blair_brown_fiscal_expansion_2001_2010 movement.
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.
