Month: 2025-11 focused on documentation improvements for riscv/riscv-cheri. The primary deliverable was clarifying the M-bit modification semantics in the docs, indicating that updating the M-bit may be a no-op for certain capabilities. This reduces user confusion and supports better onboarding and adoption. No code-level bugs were fixed this month; activity centered on documentation quality and clarity. Commit 0283e879f861878abb1dcb89468d00ae53918ac8 documents this change and is signed by Alexander Richardson.

September 2025: Delivered targeted documentation alignment for CHERI RISC-V with Zca extension naming in riscv/riscv-cheri. The work renames identifiers and file references from 'C' to 'Zca' to reflect current extension naming conventions, improving accuracy and onboarding. No major bugs fixed this month; effort focused on documentation hygiene and alignment. Overall impact: enhanced maintainability, reduced ambiguity for users and contributors, and smoother cross-team collaboration. Technologies/skills demonstrated: documentation engineering, CHERI knowledge, naming-convention governance, and version control discipline (commit tracing).

May 2025: Documentation update to reflect the exception handling change for misaligned capability data memory accesses in riscv/riscv-cheri. Previously, a misaligned access could raise a misaligned exception; the behavior now raises an access fault due to the presence of a hidden valid tag per CLEN-aligned memory region. This documentation update communicates the change in system behavior and aligns user-facing docs with the implementation. Change tracked in commit 171066f5c7883712e1660a67395bf0ebf7c67bcc ("Raise an access fault on misaligned capabilities").

April 2025: Delivered focused CHERI RISC-V documentation improvements for integration and PC extension, clarifying capability-check semantics, improving file-extension formatting readability, and clarifying PC-to-Program Counter extension. This work reduces onboarding time, minimizes interpretation errors for developers, and lowers support overhead; all changes are documentation-only with no new functionality shipped this month.

November 2024 (llvm/llvm-zorg): Stabilized bootstrapping by ensuring correct linking to installed libc++ and libc++abi, preventing build-tree layout from interfering with the libc++ installation, and improving build reliability across environments. This work reduces CI fragility and enhances developer onboarding through more reproducible builds.
