# Description of Changes
**Summary**
- Enforce wheels-only installs for CI/dev workflows where feasible and
pin `pip` to a specific, patched VCS commit as an interim mitigation.
- Replace the explicit `pip==25.2` entry with a VCS-pinned `pip`
reference in `.github/scripts/requirements_dev.in` and the regenerated
`.github/scripts/requirements_dev.txt`.
- Refresh and re-hash multiple development dependency pins in the locked
`requirements_dev.txt` to ensure reproducible installs and reduce
exposure to vulnerable transitive packages.
- Add notes and guidance for maintainers on reverting the VCS pin once
an official pip release contains the fix.
**Why the change was made**
- CVE-2025-8869 allows malicious sdists to include links that escape the
intended extraction directory, enabling arbitrary file overwrite during
`pip install`. CI and developer automation that installs dev
dependencies are at risk if they process attacker-controlled sdists.
- This PR reduces immediate attack surface by preferring wheel
installations where possible and pinning pip to a known patched commit
until an official fixed pip release is available.

# Description of Changes
- **What was changed**
- Added the `--strip-extras` option to the `pip-compile` commands in
`.github/scripts/requirements_pre_commit.txt` and
`.github/scripts/requirements_sync_readme.txt`.
- Bumped versions of CI and development dependencies:
- In `.github/scripts`: `filelock`, `identify`, `platformdirs`,
`pre-commit`, `tomlkit`
- In `testing/cucumber/requirements.txt`: `certifi`,
`charset-normalizer`, `pillow`, `pycryptodome`, `pypdf`, `reportlab`,
`typing-extensions`, and others
- Regenerated hashes for all updated packages.
- Added new batch script `scripts/generate_requirements.bat` to automate
requirement regeneration
- **Why the change was made**
- Keep dependencies up-to-date with latest patch releases to address
security fixes and compatibility improvements.
- Reduce lockfile size and remove unneeded extras by stripping optional
markers.
- Ensure CI and test environments use the most current, secure versions
of tooling.
