Statutory and effective corporate tax rates, treatment of depreciation, and international competitiveness.

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.
Successive Finance Acts from 1998 onwards layered tax incentives for property development, including Section 23/Section 50 rental reliefs, urban and rural renewal schemes, hotel and student accommodation reliefs, and Living-City and Living-over-the-Shop measures. The reliefs subsidised property investment during the Celtic Tiger property boom; many were retrospectively criticised by the 2009 Commission on Taxation as procyclical tax expenditures.
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.
