We currently have commits (especially in the notes/ directory which contains Claude chat exports) which include gitlab access tokens. We should check the entire repository for any other sensitive information, and force a history rewrite to redact this information from the repo without removing the files entirely. For now notes/ has been excluded via .gitignore, but this does not remove the history. Once redactions are made (as have been done manually in some of the current files), the .gitignore exclusion can be removed. It may make sense to include a Makefile target to handle automatically redacting this information, for use prior to committing any further exports.
