Contributed to the riscv/riscv-cheri repository by delivering three targeted documentation features over two months, focusing on clarifying complex aspects of the CHERI ISA. Addressed ambiguity in the scbndsr instruction’s rounding behavior, ensuring both base and top bounds are precisely defined to match intended semantics. Enhanced documentation around permission stripping for loaded capabilities and detailed the utidc register’s role in thread identification and compartmentalization. Used Markdown and asciidoc to draft and refine technical content, aligning closely with issue tracking and commit hygiene practices. These updates improved specification clarity, reduced misinterpretation risk, and supported downstream development and maintenance efforts.
