Comparison synthesis: OpenAI's external groups (announced 2026-10-26) organize explanation and examination; Microsoft Discovery's documentation (updated 2026-09-04) describes reusable graph memory and checkpoints; 1Cademy's undated proposal (retrieved 2026-11-08) organizes prerequisite learning with separate topic/link review. These address different tasks: developing explanations, preserving research context and preparing readers to judge. The sources in this map do not provide a comparative effectiveness study. Operational scalability remains an open question: as contributions and revisions accumulate, do comprehension, correction quality and review coverage remain adequate relative to authoring, reviewing and maintenance time? More stored outputs or more participants alone would not answer that question.
