Aug 1, 2025August 2025 (cpprefjp/site): Delivered local validation tooling and documentation improvements that strengthen content quality, version navigation, and sponsor references. Implemented a centralized local CI checks workflow (check.py) to emulate CI validation locally, along with scripts for Markdown/documentation quality controls, reference list sorting, and removal of invisible characters. Fixed primary/overload list sorting logic to ensure correct grouping order and data consistency across versions. Updated C++ standards references, See Also links, and C++26 Working Draft coverage, plus sponsor updates, improving navigability and accuracy across releases. These efforts reduce CI feedback loops, improve data integrity, and demonstrate strong scripting, documentation, and data maintenance capabilities.
