Presidential election 12 June 1993, widely regarded as Nigeria's freest to that date, was won by MKO Abiola (SDP) with ~58% over Bashir Tofa (NRC). Babangida annulled the result 23 June 1993 citing unspecified irregularities and transferred power to an Interim National Government under Ernest Shonekan 26 August. ING was overthrown by Abacha 17 November 1993. The annulment became the defining legitimacy rupture in post-1979 Nigerian civilian politics.
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.
