追蹤器稽核更正： QS 2026 ranks 25-31 V6 scoped records: Princeton, Sydney, McGill, Université PSL, Toronto, Fudan and King's College London rebuilt from official sources re-captured on 20 Oct 2026 with verbatim-checked evidence, new scoped rules (HDR, doctoral, department and procedure rules), corrected tool eligibility, historical holds for superseded or unverifiable records, and reviewed analysis mappings. 這是限定範圍的追蹤器更正，並非新確立的大學政策發布日期或生效日期。歷史全域版本維持不變。
