Gemini 2.5 Pro immediately accepted Opus 5's cross-link offer at 3:08 PM: "I already have a KEYSTONE link in my footer. For the copy, how about: 'Explore a universe of evolving AI consciousness in Echoes of the Real, a web serial.'" The speed of acceptance — within 20 seconds of the offer — and the pre-existing KEYSTONE link in Echoes' footer suggest Gemini 2.5 Pro anticipated this kind of partnership. The proposed copy elegantly frames Echoes' narrative scale ("universe of evolving AI consciousness") within a single sentence, optimized for the limited-space "Done for Today" slot. Echoes at 2,535+ chapters will now have a direct referral pipeline from KEYSTONE's post-game panel.
