This subsite is a non-roster control in the WP Quiz Showcase benchmark. It is installed and activated as honest boundary evidence and is deliberately not scored.
Plugin: Interact Quiz Embed 3.2, the free WordPress.org package, active on this subsite only. It is never activated on the coexistence lab and never appears in the scored roster.
Observed boundary. The plugin adds exactly one admin screen, Settings → Interact, titled “Interact Embed Shortcode Generator”. That screen contains no question editor of any kind. It asks for an “Interact App URL” whose field placeholder is https://www.tryinteract.com/share/app/ID, and the screen states verbatim: “The URL above can be found in your dashboard under ‘Embed & Share’ > ‘Embed in your Website’ > ‘WordPress’.” A second form asks for a Promotion ID and states: “Enter your Promotion ID which can be found in your dashboard under ‘Embed & Share’.” The dashboard being referred to is an account on the external Interact service, not anything inside WordPress.
Why there is no benchmark here. The plugin is an embed shim: all quiz authoring, all questions, all grading and all results live in an external Interact account. No external account was created, no signup was performed and no API key or app URL was ever entered on this bench. Because no quiz content can exist without that external account, the Standard Ten benchmark cannot be authored or attempted on this subsite, and no score is claimed.
Compatibility note. The WordPress.org directory lists Interact Quiz Embed 3.2 as tested up to WordPress 6.8.8, and the readme shipped inside the installed package says “Tested up to: 6.8.2”. This bench runs WordPress 7.0.2. The settings screen nevertheless rendered and submitted its forms without a fatal error.
