Rule of law as institutional substrate — contract enforcement, judicial independence, equal treatment before the law. Upstream of most other axes.
Targeted industrial and sectoral subsidies (renewable energy, chip manufacturing, agriculture, green hydrogen, etc).
Head-on collision between Hellenic Train passenger service IC62 and a freight train near Tempi on the Athens-Thessaloniki line, 28 February 2023, killing 57 (primarily students returning from Carnival). The local stationmaster at Larissa had routed the passenger train onto the wrong track; the automated ETCS signalling system (for which EU contracts dated back to 2014) was non- operational on the line. Institutional fallout included: resignation of Transport Minister Kostas Karamanlis (nephew of former PM) 1 March 2023; nationalisation of rolling-stock safety audit; 2023 supplementary budget for rail-signalling contracts; Hellenic Parliament cross-party preliminary inquiry committee 2023-2024; criminal proceedings against stationmasters and Hellenic Train executives; protest mobilisations peaking February 2024 (one-year anniversary, largest demonstrations since 2011-2012); OLYE (train drivers' union) rolling strike actions. European Public Prosecutor's Office investigation into misuse of EU rail-safety funds opened 2024. Coded as institutional-fallout policy because it produced no statute reversing the Mitsotakis programme, but altered public-trust baseline and remains a live political issue through 2025.
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.
