The Coal Industry Nationalisation Act 1946 vested the assets of approximately 800 private colliery companies in the National Coal Board (NCB), establishing a state monopoly over coal mining, processing, and wholesale distribution from 1 January 1947. Compensation was paid to former owners via government stock, and the NCB became one of the largest employers in postwar Britain, central to Attlee's programme of public ownership of the commanding heights.
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.
