Inventory windows and command surfaces
List every window or webview label, the content it can load and the operations it needs. Separate local application views from any remote-content surface. Include auxiliary windows such as settings, authentication and previews, since they can have a different trust level from the main workspace.
Inventory plugin permissions and your own Rust commands. Follow the current Tauri capability reference for the installed version, including its rules for custom command manifests. A capability file listing plugin permissions should not be mistaken for proof that every registered application command is denied unless listed.
Calculate the effective permission set
Review overlapping capabilities together. Permissions attached through several files can combine for one window, so a narrow individual file may not represent the effective boundary. Use exact labels and platform restrictions appropriate to the app, and avoid broad wildcard access without a documented need.
Remote API access deserves a separate review. Only grant it when the product requires it, and check the targeted platform constraints described by Tauri. A trusted host name is insufficient if the allowed page can contain third-party frames or content capable of reaching an unintended command.
Keep command implementation defensive
Validate argument type, size and allowed resource at the native entry point. A file-export command should operate within the intended user-selected destination rather than accept unrestricted paths from arbitrary frontend state. Scope checks must handle traversal and platform path differences correctly.
Apply account and tenant authorization on the backend for online operations. Moving an HTTP request into Rust does not make the requesting user entitled to every object. Likewise, capabilities do not repair unsafe native code or a command that intentionally bypasses its own scope.
Test denied and allowed operations
Build an owned test matrix for each window and platform. Confirm necessary operations succeed, unexpected commands are rejected and resources outside the allowed scope remain inaccessible. Include window creation and navigation behavior because a label-based boundary can be undermined by overly powerful window management.
Inspect generated schemas and the configuration selected by the actual release build. Then build, package and sign through normal native tooling. A development-only configuration is not evidence for the distributed app. Retain private symbols where needed and record the final package bytes.
CloneGuard can identify project hints, screen supported assets and organize this review. It does not prove Tauri capability correctness or execute permission tests automatically. Keep native boundary validation separate from source-map exposure and from any future reconstruction-resistance experiment.
Practical checklist
- List windows, content origins and native entry points.
- Review merged capability and custom-command permissions.
- Test native resource scopes and rejected arguments.
- Validate the actual release configuration on each target.
