Meld. St. 25 (2015-2016) Kraft til endring — Energipolitikken mot 2030 and concurrent petroleum-tax policy white paper reaffirming the ring-fenced 78% combined tax on offshore petroleum income (22% ordinary + 56% special tax post-2013 adjustment) alongside the accelerated depreciation / uplift regime. White paper preserves the SDFI (State Direct Financial Interest) framework and the symmetric loss-offset structure that makes the special tax broadly neutral at the margin on profitable fields. 2020 temporary uplift enlargement treated separately as COVID-era amendment.
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.
