Nx Cloud has identified a possible root cause for your failed CI:

The failing test "e2e-angular:e2e-ci--src/projects-linting.test.ts" encountered a package installation failure during test setup, not a failure related to the pull request's changes.

Pull Request Intent:
The PR implements functionality to propagate parent target environment variables to atomized targets. When Nx atomizes a target (splits it into individual test files like "test--path/to/file.ts"), the changes ensure that environment variables defined for the parent target (e.g., in ".test.env") are correctly applied to the atomized child targets.

The implementation adds:

• A new function "getOwnerTargetForTask()" that uses the project graph to identify the parent target for atomized tasks by checking "project.data.metadata.targetGroups"
• Updates to "getTaskSpecificEnv()" and related functions to accept and use the project graph parameter
• Logic to resolve the parent target name from atomized target names when loading environment files

Error Analysis:
The test failed with "ERR_PNPM_FETCH_404 GET http://localhost:4873/retry: Not Found - 404" during the installation of @nx/angular@22.0.0 dependencies. The package "retry" (a transitive dependency via @nx/rspack -> @rspack/dev-server -> p-retry -> retry) was not available in the local e2e test registry.

Why This Is An Environment Issue:

1. The error occurs during package installation, before any Nx task execution or environment variable loading
2. The local registry at localhost:4873 is missing the "retry" package, indicating an incomplete or corrupted registry state
3. The code changes only affect runtime environment variable resolution for tasks, not the package installation process
4. No similar failures appear in the master branch's task outputs, suggesting this is a transient registry issue
5. The failure happened during test setup when running "pnpm add -D @nx/angular@22.0.0", which is completely independent of the env variable propagation logic

No Code Fix Required:
This is an infrastructure issue with the e2e test environment's local npm registry. The PR's changes to environment variable handling for atomized targets are unrelated to package resolution. The test should pass when the registry is properly populated with all required dependencies.

A code change would likely not resolve this issue, so no action was taken.
