CODEOWNERS

This repository uses CODEOWNERS to enforce clear ownership and review accountability for critical areas of the codebase.

Purpose

The CODEOWNERS file defines who must review changes to specific files or directories before they can be merged. This ensures:

Consistent review standards

Proper subject-matter oversight

Reduced risk for sensitive or high-impact changes

Clear accountability as the project scales

How It Works

When a pull request modifies files covered by CODEOWNERS, GitHub automatically requests reviews from the designated owners.

If branch protection rules require it, approvals from CODEOWNERS are mandatory before merge.

Ownership is enforced structurally, not informally.

What Is Covered

Typical ownership areas include:

Schema and data models (risk to analytics correctness)

Validation logic (data quality and integrity)

Performance and optimization scripts

CI/CD and automation configuration

Security-sensitive configuration

Enforcement

CODEOWNERS enforcement is active only when:

Pull requests are required before merging

“Require review from Code Owners” is enabled in branch protection or rulesets

Without enforcement enabled, CODEOWNERS acts as documentation only.

Security Note

CODEOWNERS does not grant write access.
It controls review responsibility, not permissions.

Best Practices

Keep ownership scoped and specific

Assign teams where possible instead of individuals

Review ownership regularly as the codebase evolves

Pair CODEOWNERS with branch protection rules

🔧 Critical Issues Fixed

I've updated this PR to address the review findings:

✅ CODEOWNERS File

• Moved CODEOWNERS.md → .github/CODEOWNERS (correct location without .md extension)
• Updated all team references to @mr-adonis-jimenez (valid GitHub username)
• Enhanced with specific ownership patterns for SQL, Python, docs, and data files

✅ Policy Enforcement Workflow

• Restored full security validation pipeline:
  • Branch naming convention enforcement
  • Signed commit verification
  • YAML configuration linting
  • Dependency vulnerability scanning with severity thresholds
  • CI policy summaries

📋 Changes Summary

• Maintains production-ready CI/CD security posture
• GitHub will now properly enforce code ownership rules
• All policy checks are active for quality assurance
