The BasePaginator previously assumed that API responses would always be dictionaries containing a list under the specified data key. This assumption could lead to confusing `AttributeError`s (e.g., `'str' object has no attribute 'get'`) when the API returned unexpected types like lists or scalars. This change adds explicit type validation in `_extract_items`. It now raises a descriptive `TypeError` if: 1. The response payload is not a dictionary. 2. The extracted items under `data_key` are not a list. This improves robustness and debuggability when dealing with malformed responses or unexpected API behavior. Added `tests/unit/test_paginator_robustness.py` to cover these sad paths. Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com>

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs.

Applied `black` and `isort` to `imednet/core/paginator.py` and `tests/unit/test_paginator_robustness.py` to fix CI failures. Original context: Harden BasePaginator against invalid API responses by adding explicit type validation in `_extract_items`. It now raises a descriptive `TypeError` if the response payload is not a dictionary or if the extracted items are not a list.

🛑 Vulnerability: The
BasePaginatorimplicitly assumed API responses were always dictionaries, leading to obscureAttributeErrors when the API returned lists, strings, or other types. It also assumed the data underdata_keywas always a list.🛡️ Defense: Modified
imednet/core/paginator.pyto explicitly validate that the response payload is a dictionary and the extracted items are a list. It now raises a clearTypeErrorwith helpful context if these expectations are not met.🔬 Verification: Added
tests/unit/test_paginator_robustness.pywhich mocks the client to return invalid response types (list, scalar, invalid data key) and asserts that the expectedTypeErroris raised. Ranpytest tests/unit/test_paginator_robustness.pyto confirm.📊 Impact: eliminating fragility in pagination logic by converting runtime crashes into handled exceptions. Increases code confidence by handling known "sad paths".
