  "_comment": "Canonical fast-moving facts the react-ops skill encodes. scripts/check-react-facts.py asserts SKILL.md + references name these consistently (--offline) and probes the npm registry for major-version drift (--live). Edit deliberately: a change here is a skill-content decision, not housekeeping. documented_major is the major the skill's prose commits to (react/react-dom/next) or the current tracked major for ecosystem libs the prose names without pinning a version.",
