+# WebDAV Sync Workflow
+
+## ⚠️ CRITICAL RULE: VERIFY BEFORE EXECUTING
+**ALWAYS run `help <command>` first.**
+**If `help <command>` returns nothing, the command does NOT exist.**
+**Never invent commands — terminal crashes.**
+
+## 1. Install & Configure
+- `webdav-config` — configure WebDAV connection
+- `webdav-status` — verify connection
+
+## 2. Verified Commands ONLY
+| Command | Verify With | Purpose |
+|---------|-------------|---------|
+| `webdav-ls` | `help webdav-ls` | List files on server |
+| `webdav-backup` | `help webdav-backup` | Backup VFS to WebDAV |
+| `webdav-backup-list` | `help webdav-backup-list` | List backups |
+| `webdav-restore` | `help webdav-restore` | Restore from backup |
+| `webdav-push` | `help webdav-push` | Push VFS to server |
+| `webdav-pull` | `help webdav-pull` | Pull from server |
+
+## 3. What Does NOT Exist
+There is **NO CLI delete** for WebDAV files. These will CRASH:
+- `webdav-browser` ❌
+- `webdav-explorer` ❌
+- `webdav-delete` ❌
+- `webdav-rm` ❌
+
+## 4. Deleting Files
+Since `curl` is also blocked, there is **no automated way** to delete WebDAV backups from the terminal. Use the WebDAV web interface outside the terminal.
+
+## 5. For VFS Files (local filesystem)
+Use `rm <file>` — this is a real command. Verify: `help rm`
+\ No newline at end of file
