Build

Shipping is a chain of small proofs. Keep the architecture plain, automate the repeatable checks, and make rollback boring.

Production checklist

• Define the user-visible outcome.
• Keep configuration outside source code.
• Run type checks, lint, tests, and a production build.
• Package the same artifact you intend to run.
• Add a health endpoint and bounded logs.
• Expose only required ports.
• Configure automatic restart and TLS renewal.
• Verify the public URL from outside the server.
• Write down update, rollback, and backup commands.

Prefer reversible changes

Deploy a new image, check it, then remove old artifacts later. Keep content and configuration in version control; keep secrets and generated state out.

Next step

Choose one narrow outcome, create a clean baseline, and ask Codex to carry it through verification—not merely code generation.
