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

In October 2021 Ireland joined the OECD/G20 Inclusive Framework agreement on a global minimum effective corporate tax rate of 15% for in-scope multinationals (Pillar Two), and a partial reallocation of taxing rights for the largest groups (Pillar One). Joining the agreement required raising Ireland's effective minimum rate above 12.5% for affected companies, a structural break with two decades of low-rate competition strategy.
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.
