Agent Will Not Start

Check these four things first:

1. whether the project has been initialized
2. whether execution.modelId exists
3. whether the target model can be resolved in the global model pool
4. whether environment variables and project configuration are actually ready

Recommended troubleshooting order

city agent status
city agent start --foreground

Foreground startup usually makes startup-stage errors much easier to see.

If foreground mode already shows a clear configuration error, do not keep bouncing back to background mode and retrying blindly.
