Tripartite incomes-policy phases under Callaghan government extending the 1974 Social Contract framework. Phase 3 (August 1977-July 1978) set a 10% pay norm; Phase 4 (August 1978-1979) proposed a 5% norm. TUC General Council cooperated with government wage restraint in exchange for retained union rights and welfare-state protection. Phase 4 broke down in the 1978-79 Winter of Discontent when public- sector unions refused compliance.
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.
