Context

As a community member or admin
I want to set the communities nominated page collection
so it receives proper emphasis on the Content Translation dashboard

Communities can only nominate 1 collection at a time.

Solution

Community Configuration

Since local customization is not available when current wiki != target language. We'll could expose the featured collections through a MW API. CC doesn't have an API.

See example: https://gerrit.wikimedia.org/r/c/mediawiki/extensions/ContentTranslation/+/1193885

Other considerations

It is possible that communities will want to include text and or metadata with their featured collections.

---

Derived Requirement

Allow a community to nominate exactly one featured collection for a target language so it can be emphasized on the Content Translation dashboard.
The nominated collection must be configurable via Community Configuration and exposed through a MediaWiki API so it can be consumed cross-wiki when the current wiki differs from the target language.
The system must enforce a single active nomination at any time and support future extensibility for optional descriptive text or metadata associated with the nominated collection.

Test Steps

Test Case 1: Verify a community can nominate a single featured collection

Preconditions:

• User has appropriate permissions to edit Community Configuration for the target language.

1. Navigate to the Community Configuration interface for featured collections.
2. Select a collection to nominate as the featured collection.
3. Save the configuration.
4. ✅❓❌⬜ AC1: Confirm exactly one collection is marked as nominated and saved successfully.

Test Case 2: Verify only one featured collection can be nominated at a time

1. In Community Configuration, attempt to nominate a second collection while one is already nominated.
2. Save the configuration.
3. ✅❓❌⬜ AC2: Confirm the system enforces a single nomination (either by replacing the existing nomination or preventing multiple selections).

Test Case 3: Verify nominated collection is exposed via MediaWiki API

1. Make an API request that retrieves the featured collection for a given target language.
2. Inspect the API response.
3. ✅❓❌⬜ AC3: Confirm the response includes the nominated collection and accurately reflects the Community Configuration setting.

Test Case 4: Verify cross-wiki access to nominated collection

1. Open the Content Translation dashboard on a wiki that is not the target language wiki.
2. Set a translation pair whose target language has a nominated featured collection.
3. Observe the featured collection data used by the dashboard.
4. ✅❓❌⬜ AC4: Confirm the nominated collection is retrieved via the API and used correctly despite being on a different wiki.
