How can I diagnose a failed ember-cli-deploy deployment by examining its log output?

After running ember deploy with ember-cli-deploy, the command exits with a non‑zero status and the terminal shows a generic failure message, but the underlying reason for the failure is not immediately visible. The goal is to locate and interpret the detailed deployment logs that ember-cli-deploy generates so that the specific step or plugin that caused the error can be identified.

What log files or streams does ember-cli-deploy produce during a deployment run, and how can they be accessed when the deploy command fails? Are there configuration options to increase verbosity or redirect logs to a file for later inspection?
