Rule of law as institutional substrate — contract enforcement, judicial independence, equal treatment before the law. Upstream of most other axes.
Referendum held February 21, 2016 asking voters whether to amend Article 168 of the 2009 Constitution to allow continuous re-election of the President and Vice-President. The "No" side won 51.3% to 48.7% with high turnout, preserving the two-consecutive-term limit. MAS initially accepted the result but by 2017 had pursued a Constitutional Court ruling that effectively reversed it. The date "21F" became a civic rallying symbol for the subsequent 2019 opposition protests.
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.
