Presidential humanitarian pardon + right-of-grace 24 Dec 2017 granted to Alberto Fujimori (serving 25-year sentence post-2009 conviction for Barrios Altos + La Cantuta extrajudicial killings + corruption). Issued 3 days after Kenji Fujimori-led abstention bloc saved PPK from first impeachment vote. Inter-American Court of Human Rights found 30 May 2018 pardon disregarded victims' rights; Peruvian Constitutional Tribunal upheld pardon Mar 2022. Political-cost trigger for PPK resignation.
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.
