Subject: [PATCH 01/30] style: fix Annotated pattern in audit_logs.py to
 resolve Ruff B008 and maintain compatibility

Refactor `app/api/audit_logs.py` to use the `Annotated` type hint pattern while maintaining default values for dependencies using module-level singletons.

- Resolves B008: Function-call in default argument.
- Maintains compatibility with decorators (e.g., `@require_login`) that call the function without explicitly providing the `db` argument.
- Uses standard FastAPI patterns for query parameters with constant defaults.
- No changes to API runtime behavior.

Extracted file chunk saving and duplicate detection logic into separate helper functions (`_save_upload_file_chunks` and `_check_for_exact_duplicate`) to improve readability and maintainability of the `ui_upload` endpoint in `app/api/files.py`.

Subject: [PATCH 03/30] perf(onedrive): use async httpx for token refresh

Replaces the synchronous `requests.post` and `requests.get` calls in
`app/api/onedrive.py:test_onedrive_token` with an asynchronous
`httpx.AsyncClient` implementation. This unblocks the FastAPI event loop
when this endpoint is hit.

Tests were updated to mock `httpx.AsyncClient` and a sync wrapper using `asyncio.run` was added to integration tests to maintain test coverage without massive test refactoring.

Subject: [PATCH 05/30] perf(onedrive): use async httpx for token refresh

Replaces the synchronous `requests.post` and `requests.get` calls in
`app/api/onedrive.py:test_onedrive_token` with an asynchronous
`httpx.AsyncClient` implementation. This unblocks the FastAPI event loop
when this endpoint is hit.

Tests were updated to mock `httpx.AsyncClient` and a sync wrapper using `asyncio.run` was added to integration tests to maintain test coverage without massive test refactoring.

Replaces the synchronous `requests.post` and `requests.get` calls in
`app/api/onedrive.py:test_onedrive_token` with an asynchronous
`httpx.AsyncClient` implementation. This unblocks the FastAPI event loop
when this endpoint is hit.

Fixed unused requests import in `app/api/onedrive.py` and sorted imports in the testing files updated previously to adhere to the repository formatting (`ruff check --fix`).

Subject: [PATCH 07/30] perf: optimize url upload with async i/o

Replaced synchronous `requests.get` and `open().write` in the `process_url` endpoint with `httpx.AsyncClient` and `aiofiles.open`. This prevents the FastAPI event loop from blocking during large file downloads.

Updated test suite in `tests/test_url_upload.py` to use `AsyncMock` to mock `httpx.AsyncClient.stream` contexts and async generators properly, covering all original conditions and HTTP error handling paths.

Subject: [PATCH 08/30] perf: optimize url upload with async i/o

Replaced synchronous `requests.get` and `open().write` in the `process_url` endpoint with `httpx.AsyncClient` and `aiofiles.open`. This prevents the FastAPI event loop from blocking during large file downloads.

Updated test suite in `tests/test_url_upload.py` to use `AsyncMock` to mock `httpx.AsyncClient.stream` contexts and async generators properly, covering all original conditions and HTTP error handling paths.

Added dependencies `aiofiles` and `types-aiofiles` to resolve MyPy typing CI failures, and mitigated CodeQL security alerts regarding user-provided path extensions by leveraging `os.path.basename` around the generated target file paths.

Subject: [PATCH 09/30] perf: optimize url upload with async i/o

Replaced synchronous `requests.get` and `open().write` in the `process_url` endpoint with `httpx.AsyncClient` and `aiofiles.open`. This prevents the FastAPI event loop from blocking during large file downloads.

Updated test suite in `tests/test_url_upload.py` to use `AsyncMock` to mock `httpx.AsyncClient.stream` contexts and async generators properly, covering all original conditions and HTTP error handling paths.

Added dependencies `aiofiles` and `types-aiofiles` to resolve MyPy typing CI failures, and mitigated CodeQL security alerts regarding user-provided path extensions by leveraging `os.path.basename` around the generated target file paths, and filtering out non-alphanumerics from the file extension.

Subject: [PATCH 10/30] perf(onedrive): use async httpx for token refresh

Replaces the synchronous `requests.post` and `requests.get` calls in
`app/api/onedrive.py:test_onedrive_token` with an asynchronous
`httpx.AsyncClient` implementation. This unblocks the FastAPI event loop
when this endpoint is hit.

Fixed unused requests import in `app/api/onedrive.py` and sorted imports in the testing files updated previously to adhere to the repository formatting (`ruff check --fix`). Tests in `test_api_onedrive_extended.py` were also migrated to use AsyncMock properly.

Subject: [PATCH 15/30] perf: optimize url upload with async i/o

Replaced synchronous `requests.get` and `open().write` in the `process_url` endpoint with `httpx.AsyncClient` and `aiofiles.open`. This prevents the FastAPI event loop from blocking during large file downloads.

Updated test suite in `tests/test_url_upload.py` to use `AsyncMock` to mock `httpx.AsyncClient.stream` contexts and async generators properly, covering all original conditions and HTTP error handling paths.

Added dependencies `aiofiles` and `types-aiofiles` to resolve MyPy typing CI failures, and mitigated CodeQL security alerts regarding user-provided path extensions by deriving the extension from original_filename and filtering out all non-alphanumerics.

Added a new test file `tests/test_api_saved_searches.py` containing a comprehensive test suite for the CRUD operations provided in `app/api/saved_searches.py`. The suite validates happy paths, error conditions (like missing filters, name limits, duplicates), and user isolation using an in-memory SQLite database.

Added a new test file `tests/test_api_saved_searches.py` containing a comprehensive test suite for the CRUD operations provided in `app/api/saved_searches.py`. The suite validates happy paths, error conditions (like missing filters, name limits, duplicates), and user isolation using an in-memory SQLite database. Fixed Ruff formatting error that caused the CI pipeline to fail in the previous commit.

Subject: [PATCH 27/30] feat(tasks): extract and map embedded PDF metadata in
 upload_to_email

Implement extraction of embedded PDF metadata using pypdf, mapping
/Title, /Author, /Subject, /Keywords to filename, absender,
document_type, and tags respectively. JSON metadata takes precedence;
PDF metadata fills missing fields only.
