Evidence boundaries
- Screenshots show visible changed and restored page states. They do not independently prove every recorded browser action.
- ZIP export and import used Playground's native same-platform tools. The ZIP is not published or retained as a public artifact.
- Test does not validate production backup completeness, cross-host portability, restore permissions, production recovery procedures, malware detection, real-device behavior, business transactions, or recovery time objectives.
- Playground uses browser-hosted WebAssembly and SQLite. It does not reproduce a typical PHP and MySQL or MariaDB hosting stack.
- Site Health findings describe this disposable environment. They are not a security or performance assessment of another WordPress site.
