Commands or code

Before I confirm the scope, could you share:
1. Which system and terminal are you using?
2. What exact command triggered the error?
3. What are the outputs of node -v and npm -v?
4. Does the project use npm, pnpm, or yarn?
5. Is this happening locally, in CI, or during deployment?

Risk notes

Confirm the real project environment, account permissions, platform rules, and output quality before delivery. Do not ship AI-generated changes without human review, and do not claim indexing, income, deployment success, or ranking improvements without measured evidence.
