/**
 * 03-admin-plugins.spec.ts
 *
 * What: Verifies all five peptiderepo plugins are active in wp-admin and
 *       their admin pages load without PHP errors. Catches activation failures
 *       or missing plugin files after a deploy.
 * Who triggers it: Playwright chromium project (post-auth setup).
 * Dependencies: wp-admin authenticated session (from global.setup.ts).
 *
 * Plugin admin page slugs:
 *   - peptide-search-ai       → ?page=peptide-search-ai
 *   - pr-autoblogger          → ?page=pr-autoblogger
 *   - peptide-repo-core       → ?page=peptide-repo-core  (if admin page exists)
 *
 * @see C:\Users\ongte\apps\Peptide Repo CTO\app-maps\

   *
   * This test guards against the v0.19.1 regression class: Board submenu was
   * registered before the parent top-level menu page existed (both at admin_menu
   * priority 10), causing WordPress to fall back to the `admin_page_*` hookname.
   * At request time WP recomputed the hookname, found nothing, and called
   * wp_die("Invalid plugin page"). The fix (v0.19.1) moves the board hook to
   * priority 11 so the parent menu slot is populated first.
   *
   * Selector sourced from templates/admin/board-page.php: `<div id="prab-board" ...>`.
   *
   * NOTE: This test cannot be validated against prod until v0.19.1 is deployed.
   * It is included in the deploy-gate smoke suite so the bug class becomes
   * un-shippable in future. The spec compiles and lists cleanly; the test will
   * run correctly once the fix is live.
