 - **Personas** (`tests/Fixtures/personas/`): one per stack, each requiring only the top package of its stack and built like the fixture plugins, so each production build holds exactly its scoped closure and nothing unscoped. The shared persona runs in plain PHP; the core persona boots its components and runs a migration, and the settings persona saves and rejects a value through `options.php`, both where WooCommerce is absent; the woocommerce persona saves a settings tab and product data through WooCommerce's screens and logs to WooCommerce's log; the bootstrap persona runs on PHP 7.4, which many sites still run.
 - **Prefer-lowest lane** (`tests/bin/prefer-lowest.sh`): consumer-a runs with its runtime packages locked at the lowest versions its constraints allow, so a minimum too low to work fails before a consumer installs it. For the core, settings and woocommerce personas, which like every persona list their stack's mirrors as `vcs` repositories, the script keeps only the tested package on the path repository and locks every other framework package from its mirror at the lowest allowed tag, so they run only where the mirrors carry release tags.
 - **CI** runs the Integration tests once for the newest release of every WordPress branch from the floor up, read from WordPress's version API, so a new release joins without a change here; WordPress trunk runs nightly, outside pull requests.
-- **PHP 7.4 tests** (`tests/Php74/`) run with the host's PHP against a PHP 7.4 site with WordPress 6.3, through WP-CLI in its environment: the bootstrap persona passes its floors there, and a copy that needs a newer PHP shows WordPress core's message through the notice markup WordPress before 6.4 needs, both with the updater hooked.
+- **PHP 7.4 tests** (`tests/Php74/`) run with the host's PHP against a PHP 7.4 site with WordPress 6.3, through WP-CLI in its environment: the bootstrap persona passes its floors there, and a copy that needs a newer PHP shows WordPress core's message through the notice markup WordPress before 6.4 needs, both with the updater hooked; consumer-a, below its floors there, keeps its safeguard's export lock.
 - **Type tests** (`tests/PHPStan/`) are files PHPStan analyzes during `lint:php`: `assertType()` calls pin inferred types, and each expected error carries a `@phpstan-ignore` naming its identifier, so the run fails when the error disappears.
