Where this statement fits

Mononoke developer challenges Anthropic's account of building Scion

Anthropic described building its Scion source-control system with Claude in five months. Rain, a former Mononoke developer, argued that the article understated the contribution of Meta's earlier design. Rain says they have no objection to reuse but objects to attribution and presentation. Anthropic's article now carries an October 15 update explicitly crediting Mononoke and its Bonsai data model.
