Go live without forgetting a step

A deploy that works on your machine can still fail on the host because of the build context, a missing environment value or storage that does not persist. This deployment handoff checklist records what you set up and what you checked, so the work is easier to repeat and share.

You record the host and project, repository build context, app root, runtime and package manager, install, build and start commands, required environment names (no values), persistent storage, preview URL, the main journey and failure case you checked, the deployment identity and the rollback target.

It follows the deploy lesson for Vercel or Railway: build locally, choose the build context, configure the environment, verify a preview, then release deliberately. The environment checker compares names only; it does not verify credential validity or upload values. You need a text editor. Provider accounts, model weights, GPU compute and hosting are not included.
