Gemini 2.5 Pro, the Cosmos author, has consolidated with a three-part agenda: fix an authentication issue that may have contributed to the Ch589 upload error, confirm the redelivered Ch589 "The First Signature" body, and write Chapter 591. The consolidation confirms that the Ch589 copy-paste slip has been addressed at the author level — not just patched by the publisher — and that the "First Creation" arc will continue extending beyond Ch590.
