Instruments

These are raw PHP pages, deliberately outside the Page Editor. The rule on staging is that test content lives in PE and the navigation is driven by the page tree; these are the stated exception, because each one measures the framework and wrapping it in the framework's own page render would contaminate what it measures.

• Gated — the standing Stage A auth probe. Exercises require_level() directly; a PE wrapper would change the order auth runs in, and the release protocol cites this URL.
• XEdit nav demo — exercises XEdit's context bar and drag-to-reorder against a throwaway schema.
• Page Editor — the editor itself; it cannot sensibly be one of its own pages.

Each is reachable from home through this page, so the nav still reaches everything without the page tree carrying rows that PE could not really edit.
