 ## What This Is
 
@@ -55,3 +63,9 @@ User login credentials are deliberately separate from runtime agent config:
 - Selection: `AX_ENV`, `AX_USER_ENV`, `axctl login --env`, and user-authored commands that take `--env`
 
 Do not put reusable user PATs in `.ax/config.toml` or `~/.ax/config.toml`. User PATs bootstrap and mint agent credentials; agent runtime work should use agent PAT profiles or project-local agent runtime config.
+
+## How to ship
+
+1. Branch off `dev/staging` (or `main` for tight hotfixes).
+2. PR against `main`. CI runs pytest + ruff. Merge → PyPI publish on tag.
+3. `ax-cli` does not use `aws/prod` — that branch exists for historical alignment only.
