37-39: Review checkov configuration changesNew checkov arguments have been added:
--download-external-modules=true: This could impact CI performance and security- Skipping CKV_TF_1 check: Please document why this check is being skipped
Consider:
- The security implications of downloading external modules
- Whether skipping CKV_TF_1 (Ensure Terraform module sources use git URL with version tags) is appropriate given the recent addition of the helper module

8-8: Consistent region handling refactorThe changes to both resources align with the architectural decision to centralize region handling through the helpers module. This improves maintainability by reducing configuration duplication.
Consider documenting this architectural change in the module's README to explain the rationale behind using the helpers module for region determination.

5-5: Verify helper module integration
The change to use module.helpers.region aligns with the PR objective of centralizing region management. However, let's verify the helper module integration.
✅ Verification successful
Helper module integration verified successfully
The changes are consistent and properly implemented:
- The helper module is correctly configured in
shared/helpers.tfusing theterraform-core-helperssource module.helpers.regionis consistently used across the codebase in relevant files- The
regionvariable has been successfully removed from variables.tf - All references to
var.regionhave been replaced withmodule.helpers.region

21-21: Verify GCP service account configuration
The service account has been updated to use a different project (tf00 instead of tf91). Please ensure:
- The new service account exists and has the necessary permissions
- The workload identity federation is properly configured for this account
✅ Verification successful
Service account configuration appears consistent
The verification shows that:
- There are no remaining references to the old
tf91service account in the codebase - The new service account is properly configured with the workload identity provider in the same workflow file
- This is the only service account reference in the GitHub workflows
The change appears to be a clean migration to the new project's service account.

6-6: Verify compatibility with updated pre-commit hook versions
Significant version updates have been made:
- pre-commit-hooks: v4.6.0 → v5.0.0
- pre-commit-terraform: v1.95.0 → v1.96.2
- checkov: 3.2.254 → 3.2.344
Please ensure these updates are compatible with the new helper module and don't introduce breaking changes.
Also applies to: 14-14, 32-32
✅ Verification successful
Pre-commit hook version updates are safe to proceed
The version updates in .pre-commit-config.yaml are compatible with the codebase for the following reasons:
- The helper module (
terraform-core-helpers) is pinned to a specific version (v0.1.2) and doesn't have direct dependencies on pre-commit versions - The repository uses standard pre-commit hooks for common tasks (checkov, terraform-docs, etc.) which are backward compatible
- The README.md shows these tools are used for development purposes only and don't affect the core functionality of the module

15-15: Verify helpers module initialization
The change to use module.helpers.region aligns with the architectural goal of centralizing region handling. However, we should verify that the helpers module is properly initialized in this context.
✅ Verification successful
Helpers module initialization and usage verified
The helpers module is properly initialized in the codebase with a specific version (v0.1.2) from the osinfra-io repository. The module.helpers.region output is consistently used across multiple files:
- regional/main.tf
- regional/nat/main.tf (used in two resources)
- regional/nat/locals.tf (used in name construction)
While we couldn't verify the exact output definition from the remote module, the consistent usage pattern and proper module initialization indicate this is a valid architectural change for centralizing region handling.

5-5: Update documentation format
The documentation format has been updated from pre-commit-terraform to tf_docs. Ensure this change is consistent across all module documentation.
Also applies to: 45-45
✅ Verification successful
Documentation format is consistent across modules
Based on the verification results, all markdown files in the repository are using the new BEGIN_TF_DOCS format consistently. No instances of the old PRE-COMMIT-TERRAFORM format were found. The documentation format has been successfully updated across all module documentation.

14-14: Verify provider version compatibility
The Google provider has been updated to version 6.14.1. This is a major version bump from 5.x.x which may include breaking changes.
regional/README.md (3)
39-39: LGTM! Documentation formatting improvement
The HTML tag for line breaks has been properly fixed to use self-closing tags (<br/>), improving markdown rendering.
18-20: Consider using a more stable version of terraform-core-helpers
The module is depending on v0.1.2 of terraform-core-helpers which is an early version. Consider:
- Evaluating if a more stable version is available
- Adding a comment explaining why this specific version was chosen
- Setting up version constraint strategy (e.g., ~> 0.1.2 for patch updates)
14-14: Verify compatibility with major provider version upgrade
The Google provider has been upgraded from 5.x to 6.14.1. While this documentation is informational, ensure the parent module's provider configuration is compatible with this major version upgrade to avoid potential breaking changes.
README.md (1)
75-81: LGTM! Consistent documentation updates
The changes to the provider version and helpers module are consistent with the regional module documentation. The documentation structure remains well-organized and complete.
