Kubernetes YAML pitfalls Playbook

Execution steps

1. Validate input locally. Start with a validator or parser-friendly converter.
2. Locate root cause. Use line/position/error token to isolate one failing place.
3. Apply a minimal fix. Do not refactor all content at once.
4. Re-validate and continue. Once clean, convert/export safely.
