Rule of law as institutional substrate — contract enforcement, judicial independence, equal treatment before the law. Upstream of most other axes.
IFE (autonomous since 1996 reform) delivered clean 2 July 2000 presidential election certifying Fox's 42.5%-36.1% victory over PRI. Institutional confidence reinforced through midterm 2003 and contested 2006 elections. Cornerstone of alternancia-democrática credibility. IFE became INE in 2014 reform.
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.
