General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
Rule of law as institutional substrate — contract enforcement, judicial independence, equal treatment before the law. Upstream of most other axes.
Federal Republican Austerity Law (DOF 19-nov-2019) capping senior-official salaries below the President's, prohibiting certain office-related expenditures, restricting consultancy contracts, and over the term eliminating ~100 public fideicomisos (trust funds) — including health, research and disaster-response trusts — redirecting balances to the Tesorería. Central to AMLO's fiscal self-discipline frame.
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.
