Rule of law as institutional substrate — contract enforcement, judicial independence, equal treatment before the law. Upstream of most other axes.
Law no. 666 of 30 June 1912 rewrote the political electoral law and massively enlarged the electorate. Men over 30 gained the vote without literacy or property requirements, while many younger men could vote if they had completed military service or met existing education criteria. The electorate more than doubled and liberal Italy moved decisively away from a narrow notables' franchise toward mass male politics. The reform did not democratise the regime fully, but it materially broadened formal political inclusion before the First World War.
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.
