Editor’s Note

The clearest signal this week is not a new model — it’s that the ‘agent control plane’ is becoming a genuine moat. On GitHub’s 8/13 chart, orca (parallel agent fleets), brigade (org-chart-style multi-agent with long-term memory Tideline), corsair (credential isolation + approval chains) and semantica (graph-native auditable context) dominate the agent periphery.
