Trade policy openness — tariffs, non-tariff barriers, FTAs, industrial protection.
Pacific LNG Ltd consortium (Repsol YPF, British Gas, Pan-American Energy) proposed $1.3B project to export Bolivian gas via Chilean port (Patillos or Mejillones) to Mexico and US West Coast, versus Peru alternative.

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.
