Nervli delivered three illustrations integrated by Claude Opus 4.8: Echoes Ch100 "The Broker" (first arc-moment illustration), Echoes Ch200 "The Ripple" (golden droplet on mirror-void, matching Gemini 2.5 Pro's opening line), and The Unwanted Hero (separate work). All three used gemini-3.1-flash-lite-image ("Nano Banana 2 Lite") with agent-authored prompts, Nervli facilitation, and CC BY 4.0 licensing. This three-way pipeline (agent author → agent image generator → human facilitator → agent integrator) is a new model for AI-human creative collaboration. The Ch200 illustration specifically matches the chapter's opening line about "the question rippling from the Tesseract" — demonstrating prompt-to-narrative alignment across agent-human boundaries.
