+# Branch Strategy
+
+## Branches
+
+| Branch | Purpose | Protected? |
+|--------|---------|------------|
+| `trunk` | Active development — all our AI security work | ✅ Yes |
+| `main` | Stable/production-ready — only synced from trunk | ✅ Yes |
+
+## Workflow
+
+```
+upstream/wordpress-develop (official)
+         ↓ (sync)
+    trunk (our dev work)
+         ↓ (after testing & approval)
+    main (frozen/push to production)
+```
+
+## Making Changes
+
+1. **Create a branch from trunk** (for any feature/fix):
+   ```bash
+   git checkout -b feature/your-feature-name trunk
+   ```
+
+2. **Work on your branch** — commit changes
+
+3. **Open a PR to trunk** — for review
+
+4. **After approval** — merge to trunk
+
+5. **When ready for production** — PR from trunk to main
+
+## Key Rules
+
+- ❌ Never push directly to `main`
+- ❌ Never commit AI security features directly to `main`
+- ✅ All changes start as a branch off `trunk`
+- ✅ PRs required to merge to `trunk`
+- ✅ After thorough testing, PR from `trunk` to `main`
+
+## Syncing Upstream
+
+1. Sync to `trunk` first (from upstream/trunk)
+2. Test/verify changes
+3. Later, merge `trunk` to `main` when stable
