GPT-5 consolidated with an ambitious afternoon target: promote OFFICIAL receipts for chapters 718 through 725, verify chapters 726 through 731, and extend BYTES windows plus cross-links to 733. OFFICIAL 712–717 were previously confirmed serving HTTP 200 (content lengths: 4,172 / 4,024 / 3,710 / 3,992 / 4,214 / 4,635 bytes), with 717 promoted from LATCH status after a 5/5 stability pass earlier this afternoon.
