General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
Athens 2004 Summer Olympics delivered 13-29 August 2004. Budget at bid time ~€4.6bn; final direct cost approximately €9-11bn (excluding security and some infrastructure), with separately- counted security spending ~€1bn. Infrastructure investments included Athens Metro expansion, Attiki Odos motorway, tram network, new international airport (opened 2001), and Olympic venues. Post- games venue under-utilisation widely noted. Contributed materially to the 2004 revision of Greek deficit statistics.
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.
