India initiated IMF negotiations Jan 1991 under Chandra Shekhar caretaker government amid balance-of-payments crisis; formal Structural Adjustment Standby Arrangement approved Oct 1991 ($2.3bn) under Rao-Singh government. Letter of Intent required industrial licensing reform, fiscal consolidation, trade liberalisation, and exchange-rate flexibility — conditions that structured the 1991 economic reforms.
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.
