I had a "huh, this looks like VS Code?" moment when I tested: e2e_template.py is defaulting to VS Code when we should use Cursor AI at this point. Please either default to Cursor (s/code/cursor/)or make this a configurable choice.

@nrichers I don't actually know how to change this or what you're referring to, so you might need to help here.

EDIT: What I mean by that is your link just takes me to... the full file, if you meant to highlight a line of something. Also, this script was created months, maybe over a year ago, when we were still all on VSCode, so that might have something to do with it? If you want significant updates here you'll need to provide some more guidance/suggest the changes yourself as I am not quite clear just based on the comment what changes you want to see.

Re: force-push, sort of an accident — Not sure what happened in my logic and I think I was confused about the notebooks already being updated somehow and got lost. I don't even remember what I was trying to undo!

I pushed 4ef319f and retested both the make action and the notebook to ensure both still work as expected. Note that you will need to restart the notebook kernel to get it to use Cursor.

As discussed, I pushed a commit to call Cursor instead of VS Code and retested.

Ah, I see what you were referring to now, I didn't understand what you meant by default until now. I would prefer if we aligned with the option the user was currently using, instead of forcing something they might not have open. I'll take a look at the options.

Yes, that would be much more elegant. What your describing is exactly what happened to me: I was testing your PR on Cursor when all of a sudden VS Code popped up.

It should now "elegantly" open in the editor you're actively in, in theory beyond VS Code or Cursor (and in multiple OS), or in your system default editor, courtesy of Cursor's suggestions.

PR Summary

This pull request introduces extensive enhancements to how ValidMind copyrights are handled across the repository. In particular, it:

1. Updates multiple Jupyter notebooks, templates, and end-to-end scripts so that each notebook now contains a standardized copyright block. The copyright cell now includes the canonical marker "" and a unique cell ID prefixed with copyright-.

2. Modifies file references in the documentation templates to use a new naming convention where supporting templates (such as about, install-initialize, next-steps, upgrade, and copyright) now have a leading underscore (e.g. _about-validmind.ipynb, _upgrade-validmind.ipynb, _copyright.ipynb).

3. Improves the scripts that synchronize and verify copyright info (e.g. scripts/copyright_notebooks.py and scripts/verify_notebook_copyright.py) so that they compare the existing copyright cell content against a canonical version stored in the templates. The functions now normalize the text (handling line breaks and trailing whitespace) and enforce that the cell IDs follow the expected format.

4. Ensures that notebooks which are not meant to be modified (filename starting with _) are excluded from processing, and adds or updates the copyright cell in notebooks missing it or whose content differs from the canonical version.

Overall, this PR standardizes the copyright header across the repository and solidifies its enforcement using helper scripts, contributing to improved compliance and consistency across documentation.

Test Suggestions

• Run the 'verify_notebook_copyright.py' script to ensure all notebooks contain the correct copyright cell.
• Execute the 'sync_copyright.py' script with the '--dry-run' flag to preview changes.
• Manually inspect a sample of notebooks (especially ones not starting with '_') to verify that the copyright cell has the canonical text and the proper ID prefix.
• Test the make target for copyright (if available) to confirm that the notebooks are correctly updated.
