name: Deploy one production instance

# The body of a production deploy, for one geographic instance. `deploy-prd.yml`
# calls it once per instance — `us` on every green CI run, `eu` once the EU
# instance exists — so the two share one set of steps and differ only in the
# alchemy stage (`prd` / `prd-eu`), the GitHub environment, the Infisical
# environment (same variable names, that instance's values) and the AWS region.
# A caller passes the commit to deploy explicitly: inside a reusable workflow
# `github.sha` is still the default-branch head, not the commit CI ran against.

Disable credential persistence on checkout.

actions/checkout persists the GitHub token in .git/config by default. Later steps install dependencies and run bun run alchemy:deploy:prd in the same job. Repository-controlled or third-party code in these steps can read the persisted token. The deployment does not require Git authentication after checkout.
