Reform to Ley Federal del Trabajo published 30 Nov 2012 (end of Calderón sexenio, passed in cooperation with PRI-incoming Peña Nieto). Introduced trial-period contracts (up to 30 days), initial-training contracts (up to 180 days), hourly pay, part-time work, seasonal contracts, outsourcing framework (later tightened by AMLO 2021). Capped severance back-pay at 12 months. Largest labour reform since 1970.
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.
