Feature Overview (aka. Goal Summary)  

An elevator pitch (value statement) that describes the Feature in a clear, concise way.  Complete during New status.

• As a GCP customer deploying OpenShift in a shared VPC environmentI want ccoctl to automatically grant compute.subnetworks.use permissions to the host project, so that I can successfully install clusters without manual permission configuration.
• As a platform administratorI want ccoctl to handle shared VPC permissions automatically, so that I can reduce installation failures and support escalations.
• As a DevOps engineerI want seamless OpenShift installation in shared VPC environments, so that I can leverage existing network infrastructure without additional manual steps.

Goals (aka. expected user outcomes)

The observable functionality that the user now has as a result of receiving this feature. Include the anticipated primary user type/persona and which existing features, if any, will be expanded. Complete during New status.

• Automated Permission Management: Eliminate manual compute.subnetworks.use permission grants for shared VPC installations

• Enhanced Installation Success Rate: Reduce installation failures in GCP shared VPC environments
• Improved Customer Experience: Streamline the installation process for shared VPC deployments
• Reduced Support Burden: Minimize support cases related to shared VPC permission issues

• Standardized Deployment Process: Provide consistent behavior across different GCP network configurations

Requirements (aka. Acceptance Criteria):

A list of specific needs or objectives that a feature must deliver in order to be considered complete.  Be sure to include nonfunctional requirements such as security, reliability, performance, maintainability, scalability, usability, etc.  Initial completion during Refinement status.

• ccoctl automatically detects shared VPC (XPN) environment during credential creation.

• ccoctl grants compute.subnetworks.use permission to the identified host project.

• ccoctl validates that permissions were successfully applied before proceeding.

• Installation succeeds in shared VPC environments without manual intervention.

• Feature works with existing ccoctl workflows and command syntax.

• Proper error handling and rollback if permission grant fails.

Anyone reviewing this Feature needs to know which deployment configurations that the Feature will apply to (or not) once it's been completed.  Describe specific needs (or indicate N/A) for each of the following deployment scenarios. For specific configurations that are out-of-scope for a given release, ensure you provide the OCPSTRAT (for the future to be supported configuration) as well.

Use Cases (Optional):

Include use case diagrams, main success scenarios, alternative flow scenarios.  Initial completion during Refinement status.
