This is a portfolio/reference repository - the Terraform here is not wired to a live AWS account (see the README), so there's no production deployment to compromise. That said, the code is meant to be a credible starting point for a real platform, so security issues in it are worth reporting properly.
If you find a security issue in this repo's Terraform, CI/CD workflows, or policy definitions - a privilege-escalation path in the IAM trust policies, a gap in the tenant isolation model, a workflow that could be tricked into running untrusted code - please open a private report via GitHub Security Advisories rather than a public issue.
In scope: the Terraform modules, the bootstrap IAM trust policies, the
GitHub Actions workflows (including the reusable onboarding workflow's
trust boundary), and the OPA policies in policy/conftest/.
Out of scope: anything that would only matter once this were actually deployed to a real AWS account with real traffic (e.g. rate limiting, WAF rules) - this repo doesn't run a live service.
