Rule of law as institutional substrate — contract enforcement, judicial independence, equal treatment before the law. Upstream of most other axes.
General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
Tambon Council and Tambon Administrative Organization Act 1994 (revised 1999) under 1997 Constitution mandated direct election of sub-district (tambon) councils from 1999. First nationwide TAO elections held 22 May 1999 for ~7,000 sub- districts. Direct tax-raising powers, infrastructure responsibility, local-service delivery devolved to TAO level. Paired with direct election of provincial administrative organisations (PAO) from 1997 and municipal-level councils. Fiscal decentralisation framework in Decentralisation Act 1999 required 35% of government revenue to be local within 10 years (target modified, but local-share rose from ~5% to ~25% of total).
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.
