 Work must happen on the current feature branch for the task.
 
+## Git Workflow Policy

+- `develop` is the integration branch.
+- `main` is reserved for stable releases.
+- For non-trivial changes, Codex MUST work on a dedicated task branch.
+- Allowed task branch prefixes: `feature/`, `fix/`, `docs/`, `chore/`.
+- Codex MUST NOT merge into `develop` or `main`.
+- Codex may commit only on the current task branch after required checks pass.
+- The human operator reviews, merges, pushes, and deletes branches.
+
 Allowed branch prefixes when a new branch is explicitly needed:
 
 - `feature/`
 - `fix/`
-- `hotfix/`
 - `chore/`
 - `docs/`
-- `refactor/`
 
 Do not merge task branches into `develop`. Leave integration to the repository owner or a separate explicit request.

+- replace the console email backend with real SMTP settings and a valid sender address;
+- publish only nginx and terminate HTTPS at nginx or a trusted upstream reverse proxy;
+- keep `collectstatic --noinput` in the deployment flow before `up -d`;
+- persist the PostgreSQL named volume and configure tested backups before accepting bookings;
+- create the first admin account explicitly with `python manage.py createsuperuser`.
