# 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](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. When a worker looks stuck, score interventions by evidence and reversibility before acting: observe more (free, fully reversible), then nudge, then replace the worker, then restart the runtime — escalate only when observable state, not impatience, rules out the cheaper step. Stop the observe-nudge cycle once the worker reaches a terminal status or the caller's observation window ends; past that point further intervention manufactures noise, not evidence. Named failure mode — **prompt-send optimism**: treating a successfully delivered prompt as a working worker; delivery proves transport, not engagement. Anti-pattern: restarting an unresponsive worker as the first move. Corrective: capture its observable state first — a restart destroys the evidence of why it stalled, and rescue is usually cheape...
