This file appears to exist only to trigger CI/security workflows and is not referenced or used anywhere in the repository. Keeping an unused top-level test.txt adds noise to the repo history; consider removing it (or replacing with a change that has lasting value, e.g., a docs note under .github//docs/ if you need a persistent artifact).

Suggested change

	Test file to trigger security workflow
	Repository note
	This file is kept only as a small, human-readable note rather than as a CI or
	security-workflow trigger artifact.
	If a workflow needs a persistent artifact in the future, prefer adding
	repository documentation in a more purposeful location such as `.github/` or
	`docs/`.
