Monthly summary for 2025-09 (riscv/riscv-cheri): Delivered comprehensive CHERI PTE documentation enhancements to improve clarity, consistency, and contributor recognition. Key changes standardized terminology (CW renamed to CRW), clarified interactions between PTE bits CW/CD/CRG, added explicit reserved-bit handling, updated the contributor list, and refined wording related to hardware CD update behavior and CRG bit behavior. No code fixes were required this month; effort focused on documentation quality and governance to reduce onboarding time and risk in future changes. This work strengthens maintainability, reduces ambiguity in low-level PTE semantics, and supports smoother collaboration across teams.

Month 2025-08: Focused on advancing the Svucrg extension memory model in riscv/riscv-cheri, aligning PTE handling with a 3-bit scheme and introducing a Capability Dirty (CD) bit to enable independent tracking and safer memory semantics. Completed refactoring to relocate PTE bits to resolve conflicts with existing specifications, enabling safer memory semantics and future Svucrg features. All changes are tracked against a single committed change, providing clear traceability for security-related memory protections and compliance with the CHERI model.
