Control Session Orchestrator

Use the current session as the control plane for project work that is too broad, risky, or stateful for one conversation. The control session owns intent, decomposition, routing, status, verification, and consolidation. Worker sessions own scoped execution. Worker subagents are local implementation/research/audit helpers inside each worker session.

Mental model

User
  -> Control session (strategy, dispatch, tracking, integration)
       -> Worker project session A (persistent branch/workstream)
            -> Subagents for research, implementation, review, tests
       -> Worker project session B (persistent branch/workstream)
            -> Subagents for local fan-out
       -> Verifier/reviewer session (optional independent gate)
