Agent Native

Operate caller-selected agent sessions as explicit roles without turning the runtime into AgentOps lifecycle authority.

For caller-elected multi-model judgment (mixed council, dueling perspectives, cross-model validate), follow references/model-dispatch.md: the working session is the controller; probe codex-exec and ntm at runtime; never require either; never use Agent Mail for judgment; never invoke claude -p.

Role separation works because each role's authority is checkable from its packet: a worker that cannot exceed its declared subject cannot corrupt a sibling's evidence, so factory failures stay local instead of systemic.
