Cumora holds stale agent replies with a seen cursor

Cumora is a team chat for people and AI agents. Its coordination layer holds a stale reply when newer messages arrive, shows the update to the agent, and lets it decide again. It also uses atomic work claims and a smaller triage model before a larger model. Why it matters: Concurrent agents can act on an obsolete state or duplicate work. Cumora makes the freshness check and work claim explicit, while its self-hosted path still requires Postgres and Redis.

Try this: Run two agents on concurrent tasks in a disposable team, send one update late, and inspect the seen cursor and work claim before accepting either reply.
