[ ] Add Profile builder - [ ] Diagnostics UI ### Priority 2: Enhanced Features - [ ] Full profile template engine with variable substitution - [ ] Macro execution framework - [ ] Remote catalog synchronization - [ ] Module dependency graph - [ ] Health alerts and notifications ### Priority 3: Security - [ ] Enable signature verification by default - [ ] Create keyring package with official keys - [ ] Implement module sandboxing - [ ] ACL comprehensive testing --- ## Dependencies **Package**: `secubox-core` **Depends**: - `libubox` - Core OpenWrt library - `libubus` - ubus communication - `libuci` - UCI configuration - `rpcd` -
