Targeted industrial and sectoral subsidies (renewable energy, chip manufacturing, agriculture, green hydrogen, etc).
Rule of law as institutional substrate — contract enforcement, judicial independence, equal treatment before the law. Upstream of most other axes.
On 1 January 2012 the Jonathan administration announced full removal of the PMS petrol subsidy, pump price rising from N65 to N141/litre. An eight-day general strike and mass "Occupy Nigeria" protests across Lagos, Abuja, Kano and Kaduna, organised by NLC/TUC and civil society coalitions, forced partial rollback to N97/litre on 16 January 2012 — roughly 50% of the announced price increase. The House of Representatives' Farouk Lawan committee subsequently documented large-scale fraud in the subsidy regime (~N1.07 trillion over 2009-2011), implicating marketers. The episode set the template for subsequent Nigerian subsidy-removal politics until 2023.
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.
