Royal Decree-Law 3/2012, ratified as Law 3/2012, deregulated Spanish labour markets by giving firm-level agreements primacy over sector deals, ending the automatic ultraactividad of expired collective contracts, simplifying objective dismissal grounds, cutting unfair-dismissal severance from 45 to 33 days per year of service (capped at 24 months), and broadening grounds for unilateral wage and condition adjustments.
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.
