During March 2025, Peter refined the CHERI ISA documentation in the riscv/riscv-cheri repository, focusing on clarifying the rounding behavior of the scbndsr instruction. He analyzed ambiguities in the existing specification and rewrote the documentation to specify that both the base and top bounds are rounded to fully cover the requested range. This technical writing effort, using adoc and leveraging his documentation skills, addressed potential misinterpretations and aligned the documentation with intended semantics. The update improved the accuracy and maintainability of the CHERI ISA, supporting safer downstream integrations and providing clearer guidance for developers working with capability-based instructions.
