%description
Analyses government debt sustainability using the standard debt dynamics
framework from Blanchard (1990) <doi:10.1787/budget-v2-art12-en> and the
IMF Debt Sustainability Analysis methodology (IMF, 2013) and the Sovereign
Risk and Debt Sustainability Framework (IMF, 2022). Projects debt-to-GDP
paths, decomposes historical debt changes into interest, growth, and
primary balance contributions, and estimates fiscal reaction functions
following Bohn (1998) <doi:10.1162/003355398555793>. Produces stochastic
fan charts via Monte Carlo simulation, standardised stress tests, and IMF-
style heat map risk assessments. Computes S1/S2 sustainability gap
indicators used by the European Commission. All methods are pure
computation with no external dependencies beyond base R; works with fiscal
data from any source.
