| 6 | # plan what changed since each Worker's live commit, and pending migrations |

| 8 | # migrate pending D1 migrations, before any code, once check and plan pass |
| 9 | # core, edge, front the units of each stage, in jobs that share a build; |
| 10 | # a stage starts only when the one before it succeeded |
| 11 | # smoke sign-in, sign-up and the waitlist still work on g1t.sh |
| 12 | # |
| 13 | # Each run that deploys is one production deployment of g1t.sh, made by the |
| 14 | # jobs that name `environment: production` (one per run, however many jobs): |
| 15 | # in progress when the first starts, then a success or a failure when the |
| 16 | # run ends. It shows on the project's Deployments page and as the commit's |
| 17 | # `deploy / production` check. The plan job reads production's secrets |
| 18 | # with `deployment: false`, so a dry run or a change that deploys nothing |
| 19 | # makes no deployment. |
| 20 | # |
| 21 | # Needs the repository secret CLOUDFLARE_API_TOKEN (a Production row, with |
| 22 | # Containers write), the variable CLOUDFLARE_ACCOUNT_ID, and |
| 23 | # api.cloudflare.com among the project's workflow-only domains for |
| 24 | # deploy.yml in production (Settings, Guardrails), and |
| 25 | # registry.cloudflare.com there too, to find, pull and push the runner's |
| 26 | # image. A job that must build that image (the `runner-image` group) does |
| 27 | # so with its own Docker Engine, on a larger machine. Optionally, the |
| 28 | # secret STATUS_DEPLOY_TOKEN (the status Worker's secret of the same name) |
| 29 | # and status.g1t.sh among the same workflow-only domains, so status.g1t.sh |
