General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
Targeted industrial and sectoral subsidies (renewable energy, chip manufacturing, agriculture, green hydrogen, etc).
Policy posture toward energy supply security — domestic production capacity, import diversification, strategic reserves, nuclear stance, fossil-fuel mix discipline.
Japan's first FY2026 supplementary budget created a JPY3.1tn framework financed by special deficit-financing bonds. It included a JPY100bn priority support local allocation grant, restored general contingency reserves after electricity and natural-gas charge assistance, and set a JPY2.5tn reserve fund for responding to the Middle East situation and other international shocks. The MOF overview states that the reserve is for urgent expenses required to respond to energy-price effects on Japan's economy and daily life, including support tailored to local circumstances such as extra-high voltage power users and LP gas.
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.
