Teammate (agent teams)
emergingReal practice, thin evidence. Mostly vendor-stated or reported rather than measured.
The vendor's name for what this catalog calls a lane, with the coordination mechanics shipped rather than improvised: pending tasks whose dependencies are unresolved cannot be claimed, claims lock files, and each teammate has a mailbox. The documentation's own guidance is three to five, and it names dependency-heavy or same-file work as the wrong fit — which is the same constraint the lane entry states, arrived at independently.
