# Security Review

## Scope

Project:

```text
Opera Cache Cleaner
```

Reviewed version or commit:

```text
1.0.0 local workspace
```

## Code Patterns Checked

- [x] No `eval`.
- [x] No dynamic `Function` constructor.
- [x] No unsafe HTML injection found in the reviewed code.
- [x] No shell execution.
- [x] No external network calls.
- [x] No secrets committed in the current source files.
- [x] No unsafe file writes. Browser data changes are limited to cache removal.

## Dependency Review

Command:

```bash
No dependency audit command exists because the project has no package manifest or external dependencies.
```

Result:

```text
Not applicable.
```

## Runtime Review

- [x] Manifest uses least-privilege permissions for the current feature set.
- [x] No host permissions are declared.
- [x] Local storage is used only for selected range, timer settings, and last run timestamp.
- [x] Cache clearing uses `chrome.browsingData.remove({ since }, { cache: true })`.

## Release Notes

Known residual risks:

```text
No automated browser-extension integration tests exist. Perform an unpacked-extension smoke test in Opera before release.
```
