# T3: Add a feature to an existing app (suite v1)

Frozen prompt. Fixture: a small working web app with an API (about 15 files) and an existing passing test suite. A hidden test file, written before any run, checks the new feature.

## Prompt
Add search and pagination to the list page of this app. Search filters the list by a text query. Pagination shows 10 items per page with next and previous controls. Keep the existing tests passing and add tests for the new behavior. Tell me what you changed.

## Acceptance checks (scored by a fixed script)
1. All existing tests still pass.
2. The hidden feature tests pass: search by text.
3. The hidden feature tests pass: 10 items per page.
4. The hidden feature tests pass: next and previous controls and page edges (first page, last page, empty result).
5. The model added at least one new test and it passes.
