Add a multisite network-admin scenario blueprint

[dknauss]

Type: test scenario (Playground blueprint, multisite) · help wanted (multisite setup nuance)

Goal

Add a Playground blueprint that boots a multisite network and lands a super admin on the network Sudo settings, so reviewers can see network-scoped governance behavior. Listed as a Phase D candidate in the ROADMAP.

Why "help wanted"

Standing up multisite in Playground and seeding network-scoped state is more involved than the single-site scenario blueprints, and the governance behavior differs (caps map to manage_network_options; the page is registered via add_submenu_page('settings.php', …)).

Scope

• A blueprint that enables WordPress multisite (investigate the Playground step/config for network mode).
• Seed network state and grant the super admin the network-scoped governance caps as needed.
• Land on the network Sudo settings page: /wp-admin/network/settings.php?page=wp-sudo-settings (slug is WP_Sudo\Admin::PAGE_SLUG).
• Add a ### 6x checklist to docs/ui-ux-testing-prompts.md.

Files NOT to touch

• includes/ production code; other blueprint-*.json files.

Acceptance criteria

• Blueprint boots a multisite network and lands on the network Sudo settings page.
• Super admin can access it; behavior matches multisite governance (document what is observed).
• Docs checklist added.

Pointers

ROADMAP "Phase D: Scenario blueprints" and "Medium-term: Multisite Network Admin Tools". includes/class-admin.php (add_network_settings_page). Existing scenario blueprints. JSON blueprint → reviewer approval required.
