You are explaining the precedence of Claude Code configuration scopes to the team.

The correct general precedence is managed configuration, command-line arguments, local configuration, project configuration, and then user configuration.

Managed configuration has the highest authority because it contains centrally administered organizational and compliance controls that ordinary engineers must not be able to override. Command-line arguments provide temporary session-level overrides where the relevant setting permits them. Local settings apply to one user within a specific repository and take precedence over the shared project configuration. Project settings apply to every contributor using that repository and override general user preferences. User settings form the lowest tier because they provide personal defaults across projects and apply only when no higher-precedence source supplies a value.

Anthropic documents this order explicitly: managed, command line, local, project, and user. It also notes that permission rules may merge rather than behave as simple scalar overrides, and certain security-sensitive keys have specialized precedence behavior. Claude Code Configuration Scopes

The ordering allows personal customization without permitting it to defeat repository conventions or centrally mandated security requirements. Architects must still examine the merge behavior of the individual configuration property rather than assuming every array or permission rule is replaced wholesale.
