Progressivity of the personal income tax schedule, including top marginal rates, bracket spread, and targeted credits (EITC-equivalents).
Targeted industrial and sectoral subsidies (renewable energy, chip manufacturing, agriculture, green hydrogen, etc).

1.5% payroll levy on gross salary matched by a 1.5% employer contribution, introduced via the Finance Act 2023 (Jul 2023 effective date). Ruled unconstitutional on 28 Nov 2023 by the High Court for lack of legal framework and discrimination between formal and informal sectors. Reinstated by the standalone Affordable Housing Act 2024 (assented 19 Mar 2024) which extended the levy to all income earners (including informal sector) and established the Affordable Housing Board. Funds earmarked for the 250k-unit-per-annum Affordable Housing Programme. A flagship but heavily contested pillar of the Ruto fiscal/industrial programme.
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.
