Rule of law as institutional substrate — contract enforcement, judicial independence, equal treatment before the law. Upstream of most other axes.
Independence of the judiciary from executive and legislative encroachment. Specifically captures court-packing, selective prosecution, judicial reshuffles.
The Prevention of Corruption Act 1960 strengthened Singapore's anti-corruption powers and, under Lee Kuan Yew's government, was paired with an empowered Corrupt Practices Investigation Bureau, high civil-service discipline, and prosecution credibility. The policy content moved institutional enforcement rather than redistribution or macro demand management.
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.
Legacy WGI evidence is post-1996 and should not be treated as direct causal proof of the 1960 act.
