Worked on the riscv/riscv-cheri repository to enhance the CHERI ISA documentation by clarifying the rounding behavior of the scbndsr instruction. Focused on reducing ambiguity, the update established explicit rules for rounding both the base and top bounds to ensure the requested range is accurately covered. This technical writing effort, using adoc for documentation, aligned the specification with intended semantics and minimized the risk of misimplementation. The improved documentation quality supports safer downstream integrations and future maintenance, providing developers with clearer guidance. The work demonstrated attention to detail in documentation and a methodical approach to technical communication within the ISA context.
