| # Builds the multi-arch (amd64 + arm64) image from the repo Dockerfile. | |
| # * PR → build only (catches cross-arch build breaks early, e.g. an | |
| # amd64-only step slipping back in). Nothing is pushed. | |
| # * push to dev → push `:dev` + `:sha-<short>`. Pre-release, for deploying a | |
| # branch to a real instance to test it before it reaches main. | |
| # Deliberately does NOT move `:edge` or `:latest`. | |
| # * push to main → push `:edge` + `:sha-<short>` (bleeding edge). | |
| # * push a `vX.Y.Z` tag → push `:X.Y.Z`, `:X.Y`, and `:latest`, then cut a GitHub | |
| # Release. So `:latest` always tracks the newest *release*, | |
| # never raw main. | |
| # | |
| # Pin a deployment to `:sha-<short>`, never to `:dev` or `:edge` — those move under | |
| # you, and then nothing records which commit an instance is actually running. | |
