+The normal wizard chooses registered sources, dependencies, safe blocks, and sensible tool labels for you. Registered-source visualization guidance comes from `config/sources.json`, so generated prompts cannot drift from the maintained domain contract. Repository names are the only technical concepts in the default path. Use a JSON profile when you need per-source requirements and tool control.
 
 The profile and prompts are ignored by Git. Their directory uses mode `0700` and each file uses mode `0600`. They may still reveal repository names and workflow intent, so treat them as private configuration.
