The Aznar government's Real Decreto-ley 5/2001 (and Ley 12/2001) modified the Workers' Statute to ease the use of permanent contracts, reduce employer dismissal-cost differentials, and broaden the scope of part-time and temporary contracting. The reform extended the contrato de fomento de empleo with reduced severance liability designed to encourage firm-side hiring on permanent terms.
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.
