Successive UK governments have maintained statutory Green Belt protections around major conurbations through the National Planning Policy Framework, which presumes against new construction in designated Green Belt land except in very special circumstances. Originally designed under the Town and Country Planning Act framework to prevent urban sprawl, sustained protection materially restricts greenfield housing supply on the urban fringe of London and other cities.
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.
