It corrects stale current-release metadata and release narrative on the homepage, adds Task Facts and the complete previous-release list to llms.txt, separates current release from historical benchmark baseline in the research README, names Brando Schema in the comparison metadata, and corrects the examples JSON-LD so Foundation no longer appears to produce a Compiled Brand Context by itself.
