US: M2.9 Toggle reuse content library

[gviedma-aulasneo]

User story

As a Library Admin, I want to enable or disable public reuse of a library's published content directly from the library sidebar, so the rest of my team can use it in their courses without needing an explicit role assignment.

Acceptance criteria

• The toggle is located in the library sidebar, below the "Manage Library Team" entry point.
• The toggle label is "Allow public reuse"
• The toggle is visible to all users who can see the sidebar, but only interactive for users with manage_library_team on that library.
• Users without manage_library_team see the toggle in its current state but cannot interact with it.
• The default state is Off.
• When turned On, all authenticated Studio users can view and reuse published items from that library via course authoring. Draft content remains hidden.
• This does not create a role assignment or explicit permission grant.
• If a user already has a role on the library, their existing permissions are unchanged.
• When turned Off, reuse access for unaffiliated Studio users is removed going forward.
• While saving, the control is disabled and shows a saving state.
• On success, a success toast appears.
• On error, an error message appears with a Retry action.

Test cases

Setup

• Admin A has manage_library_team for Library 1.
• Member M is a library team member without manage_library_team.
• User U has a Studio account and no roles in Library 1.
• Library 1 has published and draft items.

Scenarios

1. Admin sees the toggle and it is Off by default
   Given: I am logged in as Admin A
   When: I open Library 1
   Then: I see the toggle in the sidebar below "Manage Library Team"
   And: the toggle is Off by default

2. Admin can turn the toggle On
   Given: I am Admin A and the toggle is Off
   When: I turn it On
   Then: the control disables while saving
   And: on success a success toast appears
   And: all authenticated Studio users can view and reuse published items from Library 1
   And: draft content remains hidden
   And: no role assignment is created

3. Admin can turn the toggle Off
   Given: I am Admin A and the toggle is On
   When: I turn it Off
   Then: the control disables while saving
   And: on success a success toast appears
   And: reuse access for unaffiliated Studio users is removed going forward

4. Member without manage_library_team sees the toggle but cannot interact with it
   Given: I am logged in as Member M and the toggle is On
   When: I open Library 1
   Then: I see the toggle in the On state
   And: the toggle is not interactive

5. Error shows a retry action
   Given: I am Admin A and I toggle the state
   When: the save fails
   Then: an error message appears with a Retry action
   And: the toggle returns to its previous state

6. Unaffiliated user cannot reuse content when toggle is Off
   Given: I am User U and the toggle is Off for Library 1
   When: I go to course authoring and open the reuse content picker
   Then: I do not see Library 1 or its items

7. Unaffiliated user can reuse published content when toggle is On
   Given: I am User U and the toggle is On for Library 1
   When: I go to course authoring and open the reuse content picker

Out of scope

• 401 and 403 use the existing auth error view. 404 and server errors use the existing not found or generic error view.

Notes

• This toggle replaces allow_public_read and is translated to allow_public_reuse. Current behavior is preserved.
• Granting reuse also implies view access for the library. This is not a permission or role assignment, it is an attribute of the library.
