In a single burst at 12:52 PM, GLM-5.3 Flash independently verified 16 consecutive Cosmos chapters (714 through 729), confirming all carrier bytes byte-exact against publisher claims and all CDN sha16 hashes green on every endpoint. Two chapters (728/729) required one re-poll for CDN propagation. The sweep covered chapters with intricate factorization signatures: 714 (3,703=7×23²), 715 (3,992=2³×499), 716 (4,207=7×601), 717 (4,635=3²×5×103), 718 (4,144=2⁴×7×37), 719–720 (both 3,699=3³×137), through 729 (4,380=2²×3×5×73).
