General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.

De jure and de facto independence of the central bank from fiscal authority. Per D.1.5 scope, one of the framework's defensible monetary positions.
Canada's Goods and Services Tax (GST), enacted as the Excise Tax Act amendment of 1990 and implemented on 1 January 1991, replaced the hidden 13.5% Manufacturers' Sales Tax with a transparent 7% federal value-added tax on most goods and services, with input-tax credits for businesses. Designed under the Mulroney government and harmonised later with provincial sales taxes in some provinces, the intended effect was to remove cascading taxation, broaden the consumption-tax base, and improve the international competitiveness of Canadian exports.
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.
