Add a seed lane alongside text/image: Agent Emit gains an optional seed input (graph -> agent), Agent Receive gains a seed output (agent -> graph, 0 if none), and comfy_pull/comfy_push carry it. Wire a KSampler seed into Emit to tell the agent, or have the agent comfy_push(seed=...) to drive the next generation. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
