December 2024 monthly summary for jasmin project (jasmin-lang/jasmin). Focused on delivering measurable business value by strengthening LaTeX integration and increasing correctness of code-generation translation. Key features delivered and major fixes include enhancements to LaTeX output with informative usage comments and a robust fix to EC extraction to prevent nested loop variable name collisions.

Month: 2024-11. Focused on delivering targeted tactic improvements and robust loop reasoning to enhance proof automation and correctness in EasyCrypt/easycrypt. Key features delivered: (1) Flexible split tactic with an optional conjunction index to specify which conjunction to split on, enabling targeted application when multiple conjunctions exist in a goal (commit 096ff0d77fb7e4332c16011c460e788599e8a2f4); (2) Lossless one-sided while rule for invariant-preserving proofs, adding a robust lossless proof mechanism for while-loop reasoning (commit e6c14f7a6ee0eb5e547ad3aab50547ef0b6959f5). Major bugs fixed: none reported this month. Overall impact: reduces manual proof steps, increases automation reliability, and strengthens invariant preservation in complex proofs, accelerating verification cycles. Technologies/skills demonstrated: tactic development, invariant-preserving reasoning, lossless transformation concepts, and contribution to the EasyCrypt proof infrastructure.
