Ease of hiring/firing, collective-bargaining scope, minimum wage rigidity, temporary/permanent contract regulation.
Lei 99/2003 of 27 August 2003 introduced the first unified Código do Trabalho, consolidating fragmented labour legislation into a single code. Eased certain dismissal procedures, regularised temporary contracts, revised collective-bargaining framework with greater prominence to firm-level agreements. Replaced under Lei 7/2009 by Sócrates government but set the reformed template.
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.
