Worked on enhancing the Boogie LExpr generator in the strata-org/Strata repository, focusing on improving reliability and correctness for future verification features. Addressed a critical bug by fixing incorrect typing that previously allowed generation of LExprs with free variables outside the intended context. Improved term generation by encouraging the use of factory functions and ensuring unary and binary functions are fully applied through redundant typing rules. Expanded support for bit-vector constants with various widths and deliberately avoided generating lambda expressions to simplify downstream verification. Leveraged Lean and applied expertise in compiler design, functional programming, and type theory throughout the development process.
