2003 Stability and Growth Programme responded to Portugal's 2001 4.4% deficit (first EU Excessive Deficit Procedure case) with civil- service wage and recruitment freezes, VAT rate increase (17% to 19% in June 2002), one-off revenue measures (privatisation and tax amnesty), and delayed investment programmes.

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.
