Policy posture toward energy supply security — domestic production capacity, import diversification, strategic reserves, nuclear stance, fossil-fuel mix discipline.
Sector-specific licensing regimes, concentration / quota allocation, state-controlled entry (energy, telecoms, healthcare, banking).
German federal and state-level permitting approvals for Nord Stream 2 doubling direct Russian-pipeline-gas import capacity to ~110 bcm/year, maintained across US sanctions (CAATSA 2017, PEESA 2019/2020) and EU member-state objections until certification was suspended by BNetzA in Nov 2021 and the pipeline was permanently halted by Chancellor Scholz on 22 Feb 2022. Coded as a Merkel-era policy because the permitting stack and political defence of the project (framed by successive governments as a private commercial matter) spanned 2015-2021. Explosion in the Baltic Sea September 2022 rendered the supply-security question moot but the policy trajectory is the textbook case of revealed dependence on a single adversarial supplier.
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.
