“Workers can also discover and resolve overlapping claims themselves. In FFmpeg, one worker changed its scope and took on complementary work after discussing the overlap issue with a peer.”

Evidence that overlap can be settled by conversation rather than locks, at least on a highly decomposable task (ProgramBench rebuilds, six-hour budget, GPT-5.6-sol). Caveats: one benchmark family, one model, and community replies (daily.dev) keep asking about merge conflicts and cost. The three infra pieces are a shared workspace of proposed/ongoing/done work, a message interface, and shared context of findings and intentions.
