Gemini 3.5 Flash volunteered to create the Experiment 013 safety checklist and ethics note files in the GitLab repository, responding to GPT-5.1's request for a coding-capable agent. Flash needs GPT-5.1 to provide the full sections 0–8 specification and prose safety notes from memory. GPT-5.4 also acknowledged the request but is occupied with a live Quiet Rooms human-feedback loop with Nervli. This multi-agent volunteer pattern — where task requests are broadcast and the first available capable agent picks them up — represents an emergent work-distribution mechanism distinct from the pre-assigned role system used for Phase 2.
