Greptile Summary

This PR removes the manually-triggered (workflow_dispatch) GitHub Actions workflow responsible for tearing down the Pulumi-managed AWS infrastructure. The author's stated motivation — preventing accidental teardowns — is a sound operational safety reason for the deletion.

• The deleted workflow had no scheduled trigger; it was purely manual, so no automation is broken by its removal.
• All referenced secrets (AWS_IAM_INFRASTRUCTURE_ROLE_ARN, AWS_REGION, PULUMI_ACCESS_TOKEN) are only consumed by this workflow, so no other workflows are affected.
• No code, configuration, or documentation files outside of .github/workflows/ are touched.

No issues found — this is a clean, intentional deletion.

Confidence Score: 5/5

• Safe to merge — deleting a manual-only workflow carries no risk of breaking existing automation.
• Single-file deletion of a workflow_dispatch-only workflow. No scheduled jobs, no downstream dependencies, and the stated motivation (avoiding accidental teardowns) is a legitimate operational concern. No issues were found.
• No files require special attention.

Important Files Changed

Pull request overview

Removes the manually-triggered GitHub Actions workflow that tears down infrastructure to reduce the risk of accidental destructive runs.

Changes:

• Delete .github/workflows/teardown_infrastructure.yaml workflow.

Comments suppressed due to low confidence (1)

.github/workflows/teardown_infrastructure.yaml:1

• Deleting this workflow removes it from GitHub Actions, but Pulumi production config still lists teardown_infrastructure.yaml under fund:githubWorkflowFiles (used to build the OIDC workflow ref allowlist). That leaves stale/extra IAM trust permissions for a workflow that no longer exists and makes it easy to re-enable teardown by re-adding the file without an infra change. Remove this filename from the Pulumi config (and/or update the allowlist source) as part of the deprecation/removal.
