- Updated `test-and-publish.yml` to include coverage report uploads
  for all tested Python versions.
- Stored coverage reports under `coverage/py<python-version>` for
  organized access and tracking.

…ncies

- Added `diff-cover` (>=10.2.0) as a development dependency in `pyproject.toml`.
- Modified `test-and-publish.yml` to add a new step for running `diff-cover`
  during pull request workflows.
  - Ensures new code meets a minimum 90% coverage threshold.
  - Generates a Markdown report for coverage in modified code sections.

…iguration

- Added `scripts` as a root directory for Pyright with default settings.
- Retained configurations for `examples` with Python 3.11 specified.

…verage checks

- Introduced a Python script to analyze function coverage for specified classes
  using `coverage.py` JSON output.
- Validates minimum coverage thresholds for each function and identifies
  uncovered classes or insufficiently covered functions.
- Supports generating a Markdown report for detailed coverage insights.
- Handles invalid or missing JSON inputs gracefully with meaningful error
  messages.

Assisted-by: Codex

- Updated `noxfile.py` with a new `class-coverage` session to analyze coverage
  for specified client classes using `coverage.json`.
- Updated README with instructions for using `class-coverage` to monitor
  per-function coverage and reuse existing coverage data without rerunning
  tests.
- Added utility methods in `noxfile.py` to streamline dependency installation,
  pytest argument management, and coverage file handling.

- Updated `test-and-publish.yml` with a new step to check class function
  coverage for `PdfRestClient` and `AsyncPdfRestClient`.
- Ensured minimum 90% coverage thresholds for specified classes.
- Configured Markdown reporting for detailed class function coverage data.

Assisted-by: Codex

- Add translate-to-file tests with pages/output defaults verified

- Add async summarize/markdown/ocr/extract payload branch coverage

- Add async redaction apply coverage for rgb_color serialization

Assisted-by: Codex

- Add tests to ensure `prepare_request` rejects endpoints without a leading `/`.
- Validate iterator-based file uploads for stream detection in both sync
  and async methods.
- Cover cases where the client raises errors for non-JSON success or error
  responses, verifying payload content.

Assisted-by: Codex

- Add tests ensuring `create_from_paths` supports content-type-only uploads.
- Add async test verifying `create_from_paths` supports metadata in requests.
- These directly exercise the two missing branches in _parse_path_spec
  and validate that the multipart payload includes the right
  Content-Type and custom headers.

Assisted-by: Codex

- Moved `test_live_convert_to_png` and `test_live_async_convert_to_png`
  from `tests/test_convert_to_png.py` to a new file
  `tests/live/test_live_convert_to_png.py`.
- Simplified `test_convert_to_png.py` by removing live test cases.

…tion

- Changed `git fetch` depth from `1` to `0` for full history in diff-cover.
- Full history needed for diff-cover to find the merge base.
- Updated diff-cover report generation to use
  `--format markdown:<file-path>`, avoiding warning of deprecated
  option.

…ver fetch

- Updated `git fetch` logic to handle shallow repositories properly,
  fetching full history if needed to find the merge base.
- Ensures compatibility with diff-cover requirements for pull requests.

Assisted-by: Codex

- Replaced by test coverage and the class-coverage nox session.
- Removed `scripts/check_test_parity.sh` and all references to it across
  documentation (`README.md`, `AGENTS.md`, and `TESTING_GUIDELINES.md`).
- Updated `TESTING_GUIDELINES.md` to include instructions for running
  `uvx nox -s class-coverage` to enforce minimum function-level coverage
  on key client classes (`PdfRestClient` and `AsyncPdfRestClient`).
