General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.

The Private Sector Involvement (PSI) operation completed in March 2012 swapped roughly EUR 200 billion of Greek-law sovereign bonds held by private creditors for new instruments with longer maturities and reduced face value, imposing a haircut of about 53.5% in nominal and around 75% in net-present-value terms. Athens activated retrofit collective-action clauses (Law 4050/2012) to bind holdouts, marking the largest sovereign restructuring in history.
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.
