Direction of monetary-base expansion decisions relative to trend. Separate from fiscal.transfer_expansion even when correlated.
Finance Minister Inoue Junnosuke and the Hamaguchi cabinet restored gold convertibility in January 1930 at the prewar parity after more than a decade of suspension. Because the yen returned at an overvalued rate into a worsening world slump, the decision imposed a strongly deflationary adjustment through falling prices, tighter credit, and export stress. Gold outflows and recession forced abandonment of the policy in late 1931, making it one of the clearest prewar Japanese cases of orthodox monetary contraction worsening an external downturn.
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.
