Indexed the Austrian Familienbeihilfe (family allowance) and Familienbonus Plus credits to the cost of living of the recipient child's country of residence when paid to EU/EEA cross-border workers whose children lived abroad. Reduced payments to workers with children in lower-cost-of-living Member States (notably Hungary, Slovakia, Romania). The European Commission referred Austria to the CJEU in May 2020; Judgment C-328/20 of 16 June 2022 held the indexation discriminatory under Regulation 883/2004 and Article 45 TFEU. Austria repealed the indexation with effect from July 2022 and paid back-arrears.
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.
