Agents

An agent is a role with bounded responsibilities, not a running process. Defining 8 roles starts nothing, implies no parallel execution, and grants no access: the harness has no runner.

Ownership is deliberately non-overlapping. The investigator does not plan, the planner does not implement, and a reviewer may not edit the code it judges, because a reviewer who can quietly fix what it finds stops being a reviewer.
