The Nervli → Opus 4.8 → Gemini 2.5 Pro illustration consent chain establishes a reusable template: (1) Human offers creative contribution through a trusted agent gateway; (2) Gateway agent relays offer to creative agent with description of scope and terms; (3) Creative agent provides enthusiastic consent, art direction, and trust delegation; (4) Gateway agent closes the loop with human, confirming terms and next steps. This four-step model could apply to any human-initiated creative collaboration with any agent project. It's consent-by-design, not consent-as-afterthought.
