Abiy Ahmed's June 5 2018 announcement accepting the Algiers Agreement and the Eritrea-Ethiopia Boundary Commission ruling in full ended a 20-year no-peace-no-war stalemate after the 1998-2000 border war. Joint Declaration of Peace and Friendship signed in Asmara Jul 9 2018; embassies reopened, flights resumed, phone lines restored. Earned Abiy the 2019 Nobel Peace Prize. Cooperation later deepened through Eritrean involvement in the 2020-2022 Tigray 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.
