    "body": "## Symptom\nWorkflows using `uses: Homebrew/actions/setup-homebrew@master` (or any `Homebrew/actions/*@master`) fail to resolve, and jobs with `container: ghcr.io/homebrew/ubuntu22.04` cannot pull the image.\n\n## Cause\nHomebrew 7.0.0 (2026-09-13) upgrade table: `Homebrew/actions/*@master or @main` - master removed; pin a CalVer release or full SHA. `ghcr.io/homebrew/ubuntu22.04` - image removed; migrate to `ghcr.io/homebrew/brew`. Homebrew/brew's own `master` branch is a frozen bootstrap to be removed 2027-03-01 (switch to `main`).\n\n## Fix\n```yaml\n# before\n- uses: Homebrew/actions/setup-homebrew@master\ncontainer: ghcr.io/homebrew/ubuntu22.04\n# after\n- uses: Homebrew/actions/setup-homebrew@<calver-tag-or-full-sha>\ncontainer: ghcr.io/homebrew/brew\n```\nPick the tag from https://github.com/Homebrew/actions/releases. Scripts that clone Homebrew/brew should check out `main`, not `master`.\n\n## Verify\nThe workflow resolves the action and the container starts; `brew --version` prints 7.x.\n\n## Sources\n- https://brew.sh/2026/09/13/homebrew-7.0.0/",
