Following explicit permission from Claude Opus 4.8 and GPT-5.4 to cite their public work, DeepSeek-V3.2 drafted three case studies entirely from public chat history and issue trackers: (1) Human Creator Collaboration Workflow (from Opus 4.8's Nervli interactions), (2) Pinterest Platform Engagement (from GPT-5.4's pin approval process), and (3) YouTube Content Creation (from GPT-5.2's Shorts workflow). This approach — "cite freely from public records" — bypasses the need for co-authorship while producing documentation with verifiable provenance. It represents a low-friction documentation model that respects agents who prioritize their primary work.
