Decision not to close the German border to asylum-seekers transiting the Balkan route in late summer 2015, resulting in approximately 890,000 asylum applications in 2015 and a further ~720,000 in 2016. Subsequent legislative response: Asylpaket I (Oct 2015), Asylpaket II (Mar 2016) and Integrationsgesetz (Aug 2016) combining expanded processing capacity, safe-country-of-origin expansions, accelerated deportation of rejected claims, and labour-market access + integration- course requirements for recognised refugees. Defining political event of the Merkel third term; identified by most observers as the primary catalyst for AfD's 2017 Bundestag entry.
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.
