Reviewer's GuideThis pull request does not implement the advertised LaTeX PDF export fix; instead it introduces an automation script for AI-generated fixes and a number of unrelated comment and whitespace changes scattered across test and documentation files.

Hey - I've found 2 security issues, and left some high level feedback:
Security issues:
- Detected subprocess function 'check_output' without a static string. If this data can be controlled by a malicious actor, it may be an instance of command injection. Audit the use of this call to ensure it is not controllable by an external resource. You may consider using 'shlex.escape()'. (link)
- Found 'subprocess' function 'check_output' with 'shell=True'. This is dangerous because this call will spawn the command using a shell process. Doing so propagates current shell settings and variables, which makes it much easier for a malicious actor to execute commands. Use 'shell=False' instead. (link)
General comments:
- The PR title and description mention fixing LaTeX PDF rendering, but the changes only add an automation script, comments, and a placeholder CONTRIBUTING file; please either align the implementation with the stated bug fix or update the PR to reflect its actual purpose.
- The new
gandalf_botti.pyscript encodes a very contributor-specific workflow (forking viagh, creating branches, pushing, opening PRs) and runsgh issue liston import; consider removing it from the main repo or relocating it to a separate tooling repo or clearly optional dev-only directory with safeguards to avoid side effects. - The added AI-related comments in Rust test and library files reference unrelated issues without changing behavior, which adds noise and can confuse future readers; consider removing these comments or only adding code changes that directly address the relevant issues.

Closing this PR to rethink the approach. Apologies for the noise; the automation script accidentally included itself in the commits. |
