The National Minimum Wage Act No. 9 of 2018, negotiated at NEDLAC under the Ramaphosa-led Deputy Presidency from 2015-2017 and signed into law in November 2018 to take effect 1 January 2019, introduced a statutory minimum wage of R20/hour (with lower tiers for farmworkers R18, domestic workers R15, EPWP R11). It capped sectoral-determination divergence and set an annual review mechanism.
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.
