+# Branch Protection Rules
+
+Recommended branch protection configuration for the RocketRide Server repository.
+
+## `develop` Branch (Primary Integration Branch)
+
+### Required Settings
+
+| Setting | Value | Rationale |
+|---------|-------|-----------|
+| Require pull request reviews | Yes | All changes must be peer-reviewed |
+| Required approving reviews | 1 | Minimum one approval before merge |
+| Dismiss stale reviews on new pushes | Yes | Force re-review after changes |
+| Require review from CODEOWNERS | Yes | Enforces team-based ownership (see `.github/CODEOWNERS`) |
+| Require status checks to pass | Yes | Prevents merging broken code |
+| Require branches to be up to date | Yes | Ensures CI runs against latest develop |
+| Require linear history | Yes | Keeps history clean (squash or rebase merges only) |
+| Require signed commits | No | Optional; not all contributors have GPG keys configured |
+| Include administrators | Yes | Rules apply to everyone, including admins |
+| Restrict who can push | Yes | Only merge via PR; no direct pushes |
+| Allow force pushes | No | Never allow force pushes to develop |
+| Allow deletions | No | Prevent accidental branch deletion |
+
+### Required Status Checks
+
+These checks must pass before a PR can merge to `develop`:
+
+- `CI OK` (from `ci.yml` — the gatekeeper job that aggregates all CI results)
+- `Detect secrets` (from `gitleaks.yml`)
+- `Review dependencies` (from `dependency-review.yml`)
+- `Validate PR title` (from `pr-checks.yml`)
+
+### Optional but Recommended Status Checks
+
+- `Python coverage` (from `coverage.yml` — advisory, not blocking)
+
+## `main` Branch (Production)
+
+Apply the same settings as `develop`, with these additions:
+
+| Setting | Value | Rationale |
+|---------|-------|-----------|
+| Required approving reviews | 2 | Higher bar for production releases |
+| Restrict pushes to specific teams | DevOps only | Only release managers can merge to main |
+
+## How to Configure in GitHub UI
+
+1. Go to **Settings** > **Branches** > **Add branch protection rule**
+2. Enter the branch name pattern (e.g., `develop`)
+3. Enable each setting from the tables above
+4. Under **Require status checks to pass before merging**:
+   - Search for and add each required check by name
+   - Enable **Require branches to be up to date before merging**
+5. Click **Create** (or **Save changes** if editing)
+
+### Using GitHub CLI
+
+You can also configure branch protection via `gh`:
+
+```bash
+gh api repos/{owner}/{repo}/branches/develop/protection \
+  --method PUT \
+  --field required_status_checks='{"strict":true,"contexts":["CI OK","Detect secrets","Review dependencies","Validate PR title"]}' \
+  --field enforce_admins=true \
+  --field required_pull_request_reviews='{"required_approving_review_count":1,"dismiss_stale_reviews":true,"require_code_owner_reviews":true}' \
+  --field restrictions=null \
+  --field required_linear_history=true \
+  --field allow_force_pushes=false \
+  --field allow_deletions=false
+```
+
+## Rulesets (GitHub Rulesets Alternative)
+
+GitHub Rulesets provide a newer, more flexible alternative to branch protection rules.
+They support targeting multiple branches, bypass lists, and organization-level policies.
+
+To use rulesets instead, go to **Settings** > **Rules** > **Rulesets** > **New ruleset**.
+The same settings from the tables above apply; rulesets simply offer a more granular UI.
