Analysis Rule Override Scope Across Nested Project Configurations

Question

In a code analysis platform, nested project configurations often allow teams to override inherited rule severities while sharing a common baseline. The precise boundary where an override stops applying remains unclear when projects are organized in a monorepo with multiple configuration files.

The uncertainty centers on whether an override declared in a child configuration applies only to files under that child's directory tree, or whether it also affects sibling modules that import shared libraries. Permission boundaries around who may declare overrides add another layer of complexity in multi-team repositories.

Does a project-level rule severity override in codeac apply strictly to the directory subtree of the defining configuration, or does it propagate to dependent modules outside that subtree? Is there a documented permission boundary that restricts which teams or roles may introduce overrides in shared parent configurations? If an override is scoped by directory, what is the expected behavior for generated files or vendored dependencies located inside the subtree?

Rule Override Propagation and Scope
In directory-based configuration systems, rule severity overrides apply strictly to the directory subtree where the configuration file is defined. Overrides do not propagate to dependent modules outside that subtree, nor do they affect sibling modules that import shared libraries from the overridden directory.

Inheritance Logic and Boundaries
The system typically follows a "closest-win" hierarchy. When the analysis engine evaluates a file, it searches for the nearest configuration file in the directory tree. If a child configuration exists, its settings take precedence over the parent baseline for all files within that specific folder and its descendants.

Sibling Modules: A sibling module importing a library from an overridden directory is governed by its own local configuration or the common parent baseline, not the library's local overrides.
  Generated/Vendored Files: Files located inside the subtree—including generated code or vendored dependencies—inherit the subtree's overrides by default. To prevent this, these files must be explicitly excluded using ignore patterns or a separate configuration file within the vendor directory.

Permission Boundaries
Most analysis tools do not implement internal role-based access control (RBAC) for configuration files. Instead, permission boundaries are managed at the version control level. Teams typically use CODEOWNERS files to restrict who can modify shared parent configurations while allowing individual teams to manage overrides within their own project subdirectories.

Verification Steps
To verify the scope of an override in your current environment, perform the following tests:

Child Scope: Create a child configuration with a specific rule set to warning while the parent is error. Run analysis on a file in that child directory to confirm the warning status.
  Sibling Isolation: Run analysis on a file in a sibling directory that imports the child module; confirm the error status from the parent baseline persists.
  Vendor Check: Place a dummy generated file in the child subtree and verify if the override applies.

Missing Diagnostic: To provide a more precise answer regarding permission boundaries, please specify if you are using a self-hosted configuration or a cloud-managed platform with built-in project permissions.
