The Petroleum Industry Act signed 16 August 2021 after 20 years of drafts (originally tabled 2008) rewrote Nigerian upstream, midstream and downstream oil-and-gas law. Converted NNPC into a commercial limited- liability company (NNPC Limited) subject to the Companies and Allied Matters Act, created the Nigerian Upstream Petroleum Regulatory Commission (NUPRC) and the Nigerian Midstream and Downstream Petroleum Regulatory Authority (NMDPRA), introduced a new fiscal regime (hydrocarbon tax plus CIT replacing the PPT), and established a 3% host-community development trust fund.
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.
