## Recommended Branch Protection (main branch)

1. **Require pull request before merging**
   - Require 1 approval
   - Dismiss stale reviews on new commits

2. **Require status checks**
   - Lint
   - Type check
   - Tests
   - Security scan

3. **Require signed commits** (optional but recommended)

4. **Do not allow bypassing above settings**
