+## Branch Management
+
+- Default development branch is `develop`
+- Main release branch is `main`
+- Branch protection rules are enforced:
+  - `main`: Requires PR review (1 approval), admin enforcement, no deletion, no force push
+  - `develop`: Protected from deletion but allows force push
+- PRs follow the pattern: commit to `develop` → open PR to `main` → merge once approved
+- Branch deletion on merge is disabled to preserve branch history
