James Ball enhanced the RISC-V ISA documentation and automation pipelines across the riscv/riscv-isa-manual and riscv/riscv-cheri repositories, focusing on normative rule tagging, build automation, and compliance-ready outputs. He standardized YAML-based normative rule definitions, refactored Makefile build targets, and migrated tooling from Ruby to Python to streamline CI/CD and reduce manual overhead. By improving anchor consistency, documentation clarity, and schema alignment, James enabled machine- and human-readable outputs in HTML and JSON, supporting auditability and faster onboarding. His work demonstrated depth in Python scripting, YAML configuration, and technical writing, delivering maintainable, scalable solutions for specification management and standards compliance.
During March 2026, delivered substantial ISA normative rule enhancements for riscv/riscv-isa-manual, targeting accuracy, consistency, and maintainability. Notable work includes expanding WARL normative rules for wavedrom register layouts, standardizing implementation-definitions, and clarifying vector and HPM rule coverage. The changes improve compliance tracking, reduce duplication, and enable smoother release readiness by aligning schemas, tags, and docs with the latest resources. Key outcomes: improved rule coverage for mip/mie CSRs, new impldef tagging and base/extension metadata, and dedup removal of HPM counter rules. These efforts demonstrate strong cross-cutting skills in documentation, YAML/Docs resources, and code-review discipline, delivering business value through clearer specifications and reduced risk in ISA manuals.

January 2026 monthly summary for riscv/riscv-isa-manual: Delivered a major normative rules overhaul for the RISC-V ISA manual with improved organization and accessibility, including ~2000 normative rules updates across core content and extensions. Implemented HTML and JSON outputs for normative rules to support compliance audits and easier reviewer access. Integrated upstream CSC contributions and aligned with the latest docs-resources, including submodule updates and related build tooling improvements. Resolved quality issues such as duplicates, typos, and mis-tagging, and corrected references across normative rules, ensuring robust tagging for priv/unpriv sections and key extensions. Extended build targets to generate static normative rule artifacts (norm-rules.html and norm-rules.json) for deployment and audits. Outcome: enhanced maintainability, audit readiness, and business value through faster reviews and clearer documentation for compliance-focused stakeholders.
