Jul 1, 2025July 2025: Documentation and reference improvements delivering clear business value and improved developer experience. Implemented extensive Contract Violation reference pages and corrections; added and updated C Standard I/O reference pages (stdout, stdin, stderr) along with core stdio functions. Performed comprehensive documentation cleanup (links, nolinks, inner-links), and expanded cross-links across algorithm/documentation to improve navigation. Fixed a failing test and introduced an EOF color enhancement for better UX. Maintained and refined GLOBAL_QUALIFY_LIST references and other data-driven docs to reduce maintenance burden. These changes collectively increase API discoverability, reduce support overhead, and accelerate developer onboarding and accurate technical reference usage.
