# Step 2 — Implementation Detail

1. Documented terraform fmt -check, terraform init -backend=false, and terraform validate commands in README.md and the guide.
2. Documented optional credentialed terraform plan with a saved plan file and no apply operation.
3. Added scripts/validate_artifacts.py to verify required requirements, architecture, guide, and Terraform sections.
4. Added pytest coverage for required files, four workflow phases, and the no-apply validation rule.
